This commit adds the `MINIO_KMS_REPLICATE_KEYID` env. variable.
By default - if not specified or not set to `off` - MinIO will
replicate the KMS key ID of an object.
If `MINIO_KMS_REPLICATE_KEYID=off`, MinIO does not include the
object's KMS Key ID when replicating an object. However, it always
sets the SSE-KMS encryption header. This ensures that the object
gets encrypted using SSE-KMS. The target site chooses the KMS key
ID that gets used based on the site and bucket config.

This commit allows clients to provide a set of intermediate CA
certificates (up to `MaxIntermediateCAs`) that the server will
use as intermediate CAs when verifying the trust chain from the
client leaf certificate up to one trusted root CA.
This is required if the client leaf certificate is not issued by
a trusted CA directly but by an intermediate CA. Without this commit,
MinIO rejects such certificates.

Reject new lock requests immediately when 1000 goroutines are queued
for the local lock mutex.
We do not reject unlocking, refreshing, or maintenance; they add to the count.
The limit is set to allow for bursty behavior but prevent requests from
overloading the server completely.
Currently, DeleteObjects() tries to find the object's pool before
sending a delete request. This only works well when an object has
multiple versions in different pools since looking for the pool does
not consider the version-id. When an S3 client wants to
remove a version-id that exists in pool 2, the delete request will be
directed to pool one because it has another version of the same object.
This commit will remove looking for pool logic and will send a delete
request to all pools in parallel. This should not cause any performance
regression in most of the cases since the object will unlikely exist
in only one pool, and the performance price will be similar to
getPoolIndex() in that case.
Earlier, cluster and bucket metrics were named
`minio_usage_last_activity_nano_seconds`.
The bucket level is now named as
`minio_bucket_usage_last_activity_nano_seconds`

When compression is enabled, the final object size is not calculated in
that case, we need to make sure that the provided buffer is always
more significant than the shard size, the bitrot will always calculate
the hash of blocks with shard size, except the last block.
Before https://github.com/minio/minio/pull/20575, files could pick up indices
from unrelated files if no index was added.
This would result in these files not being consistent across a set.
When loading, search for the compression indicators and check if they
are within the problematic date range, and clean up any parts that have
an index but shouldn't.
The test validates that the signature matches the one in files stored without an index.
Bumps xlMetaVersion, so this check doesn't have to be made for future versions.
It is possible delete marker was received on old pool as decom

If one object has many parts where all parts are readable but some parts
are missing from some drives, this object can be sometimes un-healable,
which is wrong.
This commit will avoid reading from drives that have missing, corrupted or
outdated xl.meta. It will also check if any part is unreadable to avoid
healing in that case.
we do not need to hold the read locks at the higher
layer instead before reading the body, instead hold
the read locks properly at the time of renamePart()

This API had missing permissions checking, allowing a user to change
their policy mapping by:
1. Craft iam-info.zip file: Update own user permission in

2. Upload it via `mc admin cluster iam import nobody iam-info.zip`
Here `nobody` can be a user with pretty much any kind of permission (but
not anonymous) and this ends up working.

`mc admin heal ALIAS/bucket/object` does not have any flag to heal

Golang http.Server will call SetReadDeadline overwriting the previous

The code assigns corrupted state to a drive for any unexpected error,

Update github.com/cosnicolaou/pbzip2 to latest version for
significant performance improvements. This update brings a 45%
reduction in processing time.
Previously, not setting http.Config.HTTPTimeout for logger webhook
was resulting in a timeout of 0, and causing "deadline exceeded"
errors in log webhook.
This change introduces a new env variable for configuring log webhook
timeout and more importantly sets it when the config is initialised.
Manual heal can return XMinioHealInvalidClientToken if the manual
healing is started in the first node, and the next mc call to get the
heal status is landed on another node. The reason is that redirection
based on the token ID is not able to redirect requests to the first node
due to a typo.
This also affects the batch cancel command if the batch is being done in
the first node, the user will never be able to cancel it due to the same
bug.
HTTP likes to slap an infinite read deadline on a connection and
do a blocking read while the response is being written.
This effectively means that a reading deadline becomes the
request-response deadline.
Instead of enforcing our timeout, we pass it through and keep
"infinite deadline" is sticky on connections.
However, we still "record" when reads are aborted, so we never overwrite that.
The HTTP server should have `ReadTimeout` and `IdleTimeout` set for the deadline to be effective.
Use --idle-timeout for incoming connections.
Since DeadlineConn would send deadline updates directly upstream,
it would race with Read/Write operations. The stdlib will perform a read,
but do an async SetReadDeadLine(unix(1)) to cancel the Read in
`abortPendingRead`. In this case, the Read may override the
deadline intended to cancel the read.
Stop updating deadlines if a deadline in the past is seen and when Close is called.
A mutex now protects all upstream deadline calls to avoid races.
This should fix the short-term buildup of...

When listing objects with metadata, avoid returning an "expires" time
metadata value when its value is the zero time as this means that no
expires value is set on the object.
The condition were incorrect as we were comparing the filter
value against the modification time object.
For example if created after filter date is after modification
time of object, that means object was created before the filter
time and should be skipped while replication because as per the
filter we need only the objects created after the filter date.

VerifyFile is only called during a heal deep scan (bitrot check).
HealObject() will fail in that case and will mark all disks corrupted and

It is a bit rare for HealObject to be called with a deep scan flag. It
is called when a HealObject with a normal scan (e.g. new drive healing)
detects a bitrot corruption, therefore healing objects with a detected
bitrot corruption will fail.
in cases where we cannot possibly know a way to read and
construct the object, it is impossible to achieve any form of
quorum via xl.meta while we have sufficient responses from
all the drives, we should return object not found.

A batch job will fail if the retry attempt is not provided. The reason
is that the code mistakenly gets the retry attempts from the job status
rather than the job yaml file.
This will also set a default empty prefix for batch expiration.
Also this will avoid trimming the prefix since the yaml decoder already
does that if no quotes were provided, and we should not trim if quotes
were provided and the user provided a leading or a trailing space.

Currently, the bucket events and replication targets are only reloaded

This commit simplifies and optimizes the decryption of large (multipart)
objects. This PR does two things:
- Re-write the init logic for the decryption reader
- Reduce the number of OEK decryptions
Before, the init logic copied some SSE HTTP request headers to
parse them later. This is simplified to parsing them right away. This
removes some fields from the decryption reader struct.
Further, the decryption reader decrypted the OEK using the client-provided
key (SSE-C) or the KMS (SSE-S3 / SSE-KMS) for each part. This is redundant
since the OEK is the same for all parts. In particular, a KMS call might be a
network request. Now, the OEK is decrypted once for the entire multipart object.
This should improve latency when reading encrypted multipart objects
and reduce requests to the KMS.

For a non-tiered object, MinIO requires that EcM (# of data blocks) of
xl.meta agree, corresponding to the number of data blocks needed to
read this object.
OTOH, tiered objects have metadata in the hot tier and data in the
warm tier. The data and its integrity are offloaded to the warm tier. This
allows us to reduce the read quorum from EcM (typically > N/2, where N -
erasure stripe width) to N/2 + 1. The simple majority of metadata
ensures consensus on what the object is and where it is
located.

Everything until `fstat` is the `os.Open` call.
Looking at the code: https://github.com/golang/go/blob/master/src/os/file_unix.go#L212-L243
It seems for every file it "tries" to see if it is pollable. This causes `syscall.SetNonblock(fd, true)` to be called. This is the first `F_SETFL`.
It then calls `f.pfd.Init("file", true)`. This will attempt to set it as pollable using `epoll_ctl`. This will always fail for files. It therefore calls `syscall.SetNonblock(fd, false)` resulting in the second `F_SETFL`.
If we set the `O_NONBLOCK` call on the initial open, we should avoid the 4 `fcntl` syscalls per file.
I don't see any way to avoid the `epoll_ctl` call, since kind is either `kindOpenFile` or `kindNonBlock`, so "pollable" will always be true. However avoiding 4 of 6 syscalls still seems worth it.
This should not have any effect, since files will end up with "nonblock" anyway.

When a fresh drive healing is finished, add more checks for the drive listing
errors. If any, re-list and heal again. Although this is an infrequent use
case to have listPathRaw() returning nil when minDisks is set to 1, we
still need to handle all possible use cases to avoid missing healing
any object.
Also, check for HealObject result to decide of an object is healed in the
fresh disk since HealObject returns nil if an object is healed in any
disk, and not in the new fresh drive.
In regular listing, this commit will avoid showing an object when its
latest version has a pending or failed deletion. In replicated setup.
It will also prevent showing older versions in the same case.
Also, sort the error map for multiple sites in ascending order
of deployment IDs, so that the error message generated is always
definitive order and same.

In addition to the metrics, add a new API that reads the batch status

completion.
Also add the batch type in the batch id, the reason is that the batch

do not know the type of batch job anymore, hence a difficulty to locate
the job report

Add a queue cleaner in reconnected that will pop old messages so `handleMessages` can
send messages without blocking and exit appropriately for the connection to be re-established.
Messages are likely dropped by the remote, but we may have some that can succeed,
so we only drop when running out of space.
Add the inlined data as base64 encoded field and try to add a string version if feasible.
Example:
```
λ xl-meta -data xl.meta
{
"8e03504e-1123-4957-b272-7bc53eda0d55": {
"bitrot_valid": true,
"bytes": 58,
"data_base64": "Z29sYW5nLm9yZy94L3N5cyB2MC4xNS4wIC8=",
"data_string": "golang.org/x/sys v0.15.0 /"
}
```
The string will have quotes, newlines escaped to produce valid JSON.
If content isn't valid utf8 or the encoding otherwise fails, only the base64 data will be added.
`-export` can still be used separately to extract the data as files (including bitrot).
* Prevents blocking when losing quorum (standard on cluster restarts).
* Time out to prevent endless buildup. Timed-out remote locks will be canceled because they miss the refresh anyway.
* Reduces latency for all calls since the wall time for the roundtrip to remotes no longer adds to the requests.
since the connection is active, the
response recorder body can grow endlessly
causing leak, as this bytes buffer is
never given back to GC due to an goroutine.
skip healing properly in scanner when drive is hotplugged
due to how the state is passed around the SkipHealing
might not be the true state() of the system always, causing
a situation where we might healing from the scanner on the
same drive which is being. Due to this competing heals get
triggered that slow each other down.
due to a historic bug in CopyObject() where
an inlined object loses its metadata, the
check causes an incorrect fallback verifying
data-dir.
CopyObject() bug was fixed in ffa91f9794 however
the occurrence of this problem is historic, so
the aforementioned check is stretching too much.
Bonus: simplify fileInfoRaw() to read xl.json as well,
also recreate buckets properly.
* Multipart SSEC checksums were not transferred.
* Remove key mismatch logging. This key is user-controlled with SSEC.
* If the source is SSEC and the destination reports ErrSSEEncryptedObject,
assume replication is good.
avoid concurrent callers for LoadUser() to even initiate
object read() requests, if an on-going operation is in progress.
this avoids many callers hitting the drives causing I/O

This commit fixes an issue in the KES client configuration
that can cause the following error when connecting to KES:
```
ERROR Failed to connect to KMS: failed to generate data key with KMS key: tls: client certificate is required
```
The Go TLS stack seems to not send a client certificate if it
thinks the client certificate cannot be validated by the peer.
In case of an API key, we don't care about this since we use
public key pinning and the X.509 certificate is just a transport
encoding.
The `GetClientCertificate` seems to be honored always such that
this error does not occur.

the reason for this is to avoid STS mappings to be

and all the credentials only loaded successfully
are properly handled.
This also avoids unnecessary cache store which was
implemented earlier for optimization.
Directory objects are used by applications that simulate the folder
structure of an on-disk filesystem. These are zero-byte objects with names
ending with '/'. They are only used to check whether a 'folder' exists in

This commit will fix one rare case of a multipart object that

It turned out that a six years old code was marking a drive offline

This can affect reading a subsequent part, though having enough shards,
but unable to construct because one drive was marked offline earlier.
This commit will remove the drive marking offline code. It will also
close the bitrotstreaming reader before marking it as nil.

Currently, on enabling callhome (or restarting the server), the callhome

It will be a better user experience to perform the first callhome
execution immediately after enabling it (or on server start if already
enabled).
Also, generate audit event on callhome execution, setting the error

Replace the `io.Pipe` from streamingBitrotWriter -> CreateFile with a fixed size ring buffer.
This will add an output buffer for encoded shards to be written to disk - potentially via RPC.
This will remove blocking when `(*streamingBitrotWriter).Write` is called, and it writes hashes and data.
With current settings, the write looks like this:
```
Outbound
┌───────────────────┐ ┌────────────────┐ ┌───────────────┐ ┌────────────────┐
│ │ Parr. │ │ (http body) │ │ │ │
│ Bitrot Hash │ Write │ Pipe │ Read │ HTTP buffer │ Write (syscall) │ TCP Buffer │
│ Erasure Shard │ ──────────► │ (unbuffered) │ ────────────► │ (64K Max) │ ───────────────────► │ (4MB) │
│ │ │ │ │ (io.Copy) │ │ │
└───────────────────┘ └────────────────┘ └───────────────┘ └────────────────┘
```
We write a Hash (32 bytes). Since the pipe is unbuffered, it will block until the 32 bytes have
been delivered to the TCP buffer, and the next Read hits the Pipe.
Then we write the shard data. This will typically be bigger than 64KB, so it will block until two blocks
have been read from the pipe.
When we insert a ring buffer:
```
Outbound
┌───────────────────┐ ┌────────────────┐ ┌───────────────┐ ┌────────────────┐
│ │ │ │ (http body) │ │ │ │
│ Bitrot Hash │ Write │ Ring Buffer │ Read │ HTTP buffer │ Write (syscall) │ TCP Buffer │
│ Erasure Shard │ ──────────► │ (2MB) │ ────────────► │ (64K Max) │ ───────────────────► │ (4MB) │
│ │ │ │ │ (io.Copy) │ │ │
└───────────────────┘ └────────────────┘ └───────────────┘ └────────────────┘
```
The hash+shard will fit within the ring buffer, so writes will not block - but will complete after a
memcopy. Reads can fill the 64KB buffer if there is data for it.
If the network is congested, the ring buffer will become filled, and all syscalls will be on full buffers.
Only when the ring buffer is filled will erasure coding start blocking.
Since there is always "space" to write output data, we remove the parallel writing since we are
always writing to memory now, and the goroutine synchronization overhead probably not worth taking.
If the output were blocked in the existing, we would still wait for it to unblock in parallel write, so it would
make no difference there - except now the ring buffer smoothes out the load.
There are some micro-optimizations we could look at later. The biggest is that, in most cases,
we could encode directly to the ring buffer - if we are not at a boundary. Also, "force filling" the
Read requests (i.e., blocking until a full read can be completed) could be investigated and maybe
allow concurrent memory on read and write.
Metrics being added:
- read_tolerance: No of drive failures that can be tolerated without
disrupting read operations
- write_tolerance: No of drive failures that can be tolerated without
disrupting write operations
- read_health: Health of the erasure set in a pool for read operations
(1=healthy, 0=unhealthy)
- write_health: Health of the erasure set in a pool for write operations
(1=healthy, 0=unhealthy)
Adds regression test for #19699
Failures are a bit luck based, since it requires objects to be placed on different sets.
However this generates a failure prior to #19699
* Revert "Revert "Fix incorrect merging of slash-suffixed objects (#19699)""
This reverts commit f30417d9a8.
* Don't override when suffix doesn't match. Instead rely on quorum for each.
Instead of having "online" and "healing" as two metrics, replace with a
single metric "health" which can have following values:
0 = offline
1 = healthy
2 = healing
If two objects share everything but one object has a slash prefix, those would be merged in listings,
with secondary properties used for a tiebreak.
Example: An object with the key `prefix/obj` would be merged with an object named `prefix/obj/`.
While this violates the [no object can be a prefix of another](https://min.io/docs/minio/linux/operations/concepts/thresholds.html#conflicting-objects), let's resolve these.
If we have an object with 'name' and a directory named 'name/' discard the directory only - but allow objects
of 'name' and 'name/' (xldir) to be uniquely returned.
Regression from #15772
canceled callers might linger around longer,
can potentially overwhelm the system. Instead
provider a caller context and canceled callers
don't hold on to them.
Bonus: we have no reason to cache errors, we should
never cache errors otherwise we can potentially have
quorum errors creeping in unexpectedly. We should
let the cache when invalidating hit the actual resources
instead.
LastPong is saved as nanoseconds after a connection or reconnection but
saved as seconds when receiving a pong message. The code deciding if
a pong is too old can be skewed since it assumes LastPong is only in
seconds.

This commit adds support for MinKMS. Now, there are three KMS
implementations in `internal/kms`: Builtin, MinIO KES and MinIO KMS.
Adding another KMS integration required some cleanup. In particular:
- Various KMS APIs that haven't been and are not used have been
removed. A lot of the code was broken anyway.
- Metrics are now monitored by the `kms.KMS` itself. For basic
metrics this is simpler than collecting metrics for external
servers. In particular, each KES server returns its own metrics
and no cluster-level view.
- The builtin KMS now uses the same en/decryption implemented by
MinKMS and KES. It still supports decryption of the previous
ciphertext format. It's backwards compatible.
- Data encryption keys now include a master key version since MinKMS
supports multiple versions (~4 billion in total and 10000 concurrent)
per key name.

AWS S3 returns the actual object size as part of XML

Returning errors on listings is impossible with the current API, so document that.

ILM actions due to ExpiredObjectDeleteAllVersions and

Note: This applies to object versions which may not have retention
configured on them. This applies to all object versions in this bucket,
including those created before the retention config was applied.
Per-bucket metrics endpoints always start with /bucket and the bucket
name is appended to the path. e.g. if the collector path is /bucket/api,
the endpoint for the bucket "mybucket" would be

When listing, with drives returning `errFileNotFound,` `errVolumeNotFound`, or `errUnformattedDisk,`,
we could get below `minDisks` drives being left.
This would result in a quorum never being reachable for any object. Therefore, the listing
would continue, but no results would ever be produced.
Include `fnf` in the mindisk check since it is incremented on these errors. This will stop
listing when minDisks are left.
Allow `opts.minDisks` to not return errVolumeNotFound or errFileNotFound and return that.
That will allow for good results even if disks return something else.
We switch `errUnformattedDisk` to a regular error. If we have enough of those, we should just fail.
Typically not all drives are connected, so we delay 3 minutes before resuming.
This greatly reduces risk of starting to list unconnected drives, or drives we risk being disconnected soon.
This delay is not applied when starting with an admin call.
ConsoleUI like applications rely on combination of
ListServiceAccounts() and InfoServiceAccount() to populate
UI elements, however individually these calls can be slow
causing the entire UI to load sluggishly.
i.e., this rule element doesn't apply to DEL markers.
This is a breaking change to how ExpiredObejctDeleteAllVersions
functions today. This is necessary to avoid the following highly probable
footgun scenario in the future.
Scenario:
The user uses tags-based filtering to select an object's time to live(TTL).
The application sometimes deletes objects, too, making its latest
version a DEL marker. The previous implementation skipped tag-based filters
if the newest version was DEL marker, voiding the tag-based TTL. The user is
surprised to find objects that have expired sooner than expected.
* Add DelMarkerExpiration action
This ILM action removes all versions of an object if its
the latest version is a DEL marker.
```xml
<DelMarkerObjectExpiration>
<Days> 10 </Days>
</DelMarkerObjectExpiration>
```
1. Applies only to objects whose,
• The latest version is a DEL marker.
• satisfies the number of days criteria
2. Deletes all versions of this object
3. Associated rule can't have tag-based filtering
Includes,

At server startup, LDAP configuration is validated against the LDAP
server. If the LDAP server is down at that point, we need to cleanly
disable LDAP configuration. Previously, LDAP would remain configured but
error out in strange ways because initialization did not complete
without errors.
When importing access keys (i.e. service accounts) for LDAP accounts,
we are requiring groups to exist under one of the configured group base
DNs. This is not correct. This change fixes this by only checking for
existence and storing the normalized form of the group DN - we do not
return an error if the group is not under a base DN.
Test is updated to illustrate an import failure that would happen
without this change.
Existing IAM import logic for LDAP creates new mappings when the
normalized form of the mapping key differs from the existing mapping key
in storage. This change effectively replaces the existing mapping key by
first deleting it and then recreating with the normalized form of the
mapping key.
For e.g. if an older deployment had a policy mapped to a user DN -
`UID=alice1,OU=people,OU=hwengg,DC=min,DC=io`
instead of adding a mapping for the normalized form -
`uid=alice1,ou=people,ou=hwengg,dc=min,dc=io`
we should replace the existing mapping.
This ensures that duplicates mappings won't remain after the import.
Some additional cleanup cases are also covered. If there are multiple
mappings for the name normalized key such as:
`UID=alice1,OU=people,OU=hwengg,DC=min,DC=io`
`uid=alice1,ou=people,ou=hwengg,DC=min,DC=io`
`uid=alice1,ou=people,ou=hwengg,dc=min,dc=io`
we check if the list of policies mapped to all these keys are exactly
the same, and if so remove all of them and create a single mapping with
the normalized key. However, if the policies mapped to such keys differ,
the import operation returns an error as the server cannot automatically
pick the "right" list of policies to map.
When inspecting files like `.minio.sys/pool.bin` that may be present on multiple sets, use signature to separate them.
Also fixes null versions to actually be useful with `-export -combine`.
`minio_cluster_webhook_queue_length` was wrongly defined as `counter`
where-as it should be `gauge`
Following were wrongly defined as `gauge` when they should actually be
`counter`:
- minio_bucket_replication_sent_bytes
- minio_bucket_replication_received_bytes
- minio_bucket_replication_total_failed_bytes
- minio_bucket_replication_total_failed_count
When LDAP is enabled, previously we were:
- rejecting creation of users and groups via the IAM import functionality
- throwing a `not a valid DN` error when non-LDAP group mappings are present
This change allows for these cases as we need to support situations
where the MinIO server contains users, groups and policy mappings
created before LDAP was enabled.
instead upon any error in renameData(), we still
preserve the existing dataDir in some form for
recoverability in strange situations such as out
of disk space type errors.
Bonus: avoid running list and heal() instead allow
versions disparity to return the actual versions,
uuid to heal. Currently limit this to 100 versions
and lesser disparate objects.

RenameData could start operating on inline data after timing out
and the call returned due to WithDeadline.
This could cause a buffer to write to the inline data being written.
Since no writes are in `RenameData` and the call is canceled,
this doesn't present a corruption issue. But a race is a race and
should be fixed.
Copy inline data to a fresh buffer.
This PR makes a feasible approach to handle all the scenarios
that we must face to avoid returning "panic."
Instead, we must return "errServerNotInitialized" when a
bucketMetadataSys.Get() is called, allowing the caller to
retry their operation and wait.
Bonus fix the way data-usage-cache stores the object.
Instead of storing usage-cache.bin with the bucket as
`.minio.sys/buckets`, the `buckets` must be relative
to the bucket `.minio.sys` as part of the object name.
Otherwise, there is no way to decommission entries at
`.minio.sys/buckets` and their final erasure set positions.
A bucket must never have a `/` in it. Adds code to read()
from existing data-usage.bin upon upgrade.

If there are multiple existing DN mappings for the same normalized DN,
if they all have the same policy mapping value, we pick one of them of
them instead of returning an import error.
This is a change to IAM export/import functionality. For LDAP enabled
setups, it performs additional validations:
- for policy mappings on LDAP users and groups, it ensures that the
corresponding user or group DN exists and if so uses a normalized form
of these DNs for storage
- for access keys (service accounts), it updates (i.e. validates
existence and normalizes) the internally stored parent user DN and group
DNs.
This allows for a migration path for setups in which LDAP mappings have
been stored in previous versions of the server, where the name of the
mapping file stored on drives is not in a normalized form.
An administrator needs to execute:
`mc admin iam export ALIAS`
followed by
`mc admin iam import ALIAS /path/to/export/file`
The validations are more strict and returns errors when multiple
mappings are found for the same user/group DN. This is to ensure the
mappings stored by the server are unambiguous and to reduce the
potential for confusion.
Bonus **bug fix**: IAM export of access keys (service accounts) did not
export key name, description and expiration. This is fixed in this
change too.
Reading the list metacache is not protected by a lock; the code retries when it fails
to read the metacache object, however, it forgot to re-read the metacache object
from the drives, which is necessary, especially if the metacache object is inlined.
This commit will ensure that we always re-read the metacache object from the drives
when it is retrying.
When resuming a versioned listing where `version-id-marker=null`, the `null` object would
always be returned, causing duplicate entries to be returned.
Add check against empty version

on setups with 1000's of drives these are all
quite expensive operations.
The rest of the peer clients were not consistent across nodes. So, meta cache requests

This fixes a regression from #19358 which prevents policy mappings
created in the latest release from being displayed in policy entity
listing APIs.
This is due to the possibility that the base DNs in the LDAP config are
not in a normalized form and #19358 introduced normalized of mapping
keys (user DNs and group DNs). When listing, we check if the policy
mappings are on entities that parse as valid DNs that are descendants of
the base DNs in the config.

This commit replaces the `KMS.Stat` API call with a

checks fail in cases where the KMS backend is offline.

Instead of relying on user input values, we use the DN value returned by
the LDAP server.
This handles cases like when a mapping is set on a DN value
`uid=svc.algorithm,OU=swengg,DC=min,DC=io` with a user input value (with
unicode variation) of `uid=svc﹒algorithm,OU=swengg,DC=min,DC=io`. The
LDAP server on lookup of this DN returns the normalized value where the
unicode dot character `SMALL FULL STOP` (in the user input), gets
replaced with regular full stop.
Bonus: remove persistent md5sum calculation, turn-off

Object names of directory objects qualified for ExpiredObjectAllVersions
must be encoded appropriately before calling on deletePrefix on their
erasure set.
e.g., a directory object and regular objects with overlapping prefixes
could lead to the expiration of regular objects, which is not the
intention of ILM.
```
bucket/dir/ ---> directory object
bucket/dir/obj-1
```
When `bucket/dir/` qualifies for expiration, the current implementation would
remove regular objects under the prefix `bucket/dir/`, in this case,
`bucket/dir/obj-1`.
In handlers related to health diagnostics e.g. CPU, Network, Partitions,

This commit will always ensure that a pool's canceled/failed/completed

This commit changes how MinIO generates the object encryption key (OEK)
when encrypting an object using server-side encryption.
This change is fully backwards compatible. Now, MinIO generates
the OEK as following:
```
Nonce = RANDOM(32) // generate 256 bit random value
OEK = HMAC-SHA256(EK, Context || Nonce)
```
Before, the OEK was computed as following:
```
Nonce = RANDOM(32) // generate 256 bit random value
OEK = SHA256(EK || Nonce)
```
The new scheme does not technically fix a security issue but
uses a more familiar scheme. The only requirement for the
OEK generation function is that it produces a (pseudo)random value
for every pair (`EK`,`Nonce`) as long as no `EK`-`Nonce` combination
is repeated. This prevents a faulty PRNG from repeating or generating
a "bad" key.
The previous scheme guarantees that the `OEK` is a (pseudo)random
value given that no pair (`EK`,`Nonce`) repeats under the assumption
that SHA256 is indistinguable from a random oracle.
The new scheme guarantees that the `OEK` is a (pseudo)random value
given that no pair (`EK`, `Nonce`) repeats under the assumption that
SHA256's underlying compression function is a PRF/PRP.
While the later is a weaker assumption, and therefore, less likely
to be false, both are considered true. SHA256 is believed to be
indistinguable from a random oracle AND its compression function
is assumed to be a PRF/PRP.
As far as the OEK generating is concerned, the OS random number
generator is not required to be pseudo-random but just non-repeating.
Apart from being more compatible to standard definitions and
descriptions for how to generate crypto. keys, this change does not
have any impact of the actual security of the OEK key generation.

When an object qualifies for both tiering and expiration rules and is
past its expiration date, it should be expired without requiring to tier
it, even when tiering event occurs before expiration.
Merging same-object - multiple versions from different pools would not always result in correct ordering.
When merging keep inputs separate.

configure batch size to send audit/logger events
in batches instead of sending one event per connection.
this is mainly to optimize the number of requests
we make to webhook endpoint.
Currently, the progress of the batch job is saved in inside the job
request object, which is normally not supported by MinIO. Though there
is no apparent bug, it is better to fix this now.
Batch progress is saved in .minio.sys/batch-jobs/reports/

our PoolNumber calculation was costly,
while we already had this information per
endpoint, we needed to deduce it appropriately.
This PR addresses this by assigning PoolNumbers
field that carries all the pool numbers that
belong to a server.
properties.PoolNumber still carries a valid value
only when len(properties.PoolNumbers) == 1, otherwise
properties.PoolNumber is set to math.MaxInt (indicating
that this value is undefined) and then one must rely
on properties.PoolNumbers for server participation
in multiple pools.
addresses the issue originating from #11327
simplify audit webhook worker model
fixes couple of bugs like
- ping(ctx) was creating a logger without updating
number of workers leading to incorrect nWorkers
scaling, causing an additional worker that is not
tracked properly.
- h.logCh <- entry could potentially hang for when
the queue is full on heavily loaded systems.
there can be a sudden spike in tiny allocations,
due to too much auditing being done, also don't hang
on the
```
h.logCh <- entry
```
after initializing workers if you do not have a way to
dequeue for some reason.
This commits adds support for using the `--endpoint` arg when creating a
tier of type `azure`. This is needed to connect to Azure's Gov Cloud
instance. For example,
```
mc ilm tier add azure TARGET TIER_NAME \
--account-name ACCOUNT \
--account-key KEY \
--bucket CONTAINER \
--endpoint https://ACCOUNT.blob.core.usgovcloudapi.net
--prefix PREFIX \
--storage-class STORAGE_CLASS
```
Prior to this, the endpoint was hardcoded to `https://ACCOUNT.blob.core.windows.net`.
The docs were even explicit about this, stating that `--endpoint` is:
"Required for `s3` or `minio` tier types. This option has no effect for any
other value of `TIER_TYPE`."
Now, if the endpoint arg is present it will be used. If not, it will
fall back to the same default behavior of `ACCOUNT.blob.core.windows.net`.
Remove api.expiration_workers config setting which was inadvertently left behind. Per review comment
https://github.com/minio/minio/pull/18926, expiration_workers can be configured via ilm.expiration_workers.
ext4, xfs support this behavior however
btrfs, nfs may not support it properly.
in-case when we see Nlink < 2 then we know
that we need to fallback on readdir()
fixes a regression from #19100fixes#19181
The middleware sets up tracing, throttling, gzipped responses and
collecting API stats.
Additionally, this change updates the names of handler functions in
metric labels to be the same as the name derived from Go lang reflection
on the handler name.
The metric api labels are now stored in memory the same as the handler
name - they will be camelcased, e.g. `GetObject` instead of `getobject`.
For compatibility, we lowercase the metric api label values when emitting the metrics.
- Use a shared worker pool for all ILM expiry tasks
- Free version cleanup executes in a separate goroutine
- Add a free version only if removing the remote object fails
- Add ILM expiry metrics to the node namespace
- Move tier journal tasks to expiryState
- Remove unused on-disk journal for tiered objects pending deletion
- Distribute expiry tasks across workers such that the expiry of versions of
the same object serialized
- Ability to resize worker pool without server restart
- Make scaling down of expiryState workers' concurrency safe; Thanks

With this commit, MinIO generates root credentials automatically
and deterministically if:
- No root credentials have been set.
- A KMS (KES) is configured.
- API access for the root credentials is disabled (lockdown mode).
Before, MinIO defaults to `minioadmin` for both the access and
secret keys. Now, MinIO generates unique root credentials
automatically on startup using the KMS.
Therefore, it uses the KMS HMAC function to generate pseudo-random
values. These values never change as long as the KMS key remains
the same, and the KMS key must continue to exist since all IAM data
is encrypted with it.
Backward compatibility:
This commit should not cause existing deployments to break. It only
changes the root credentials of deployments that have a KMS configured
(KES, not a static key) but have not set any admin credentials. Such
implementations should be rare or not exist at all.
Even if the worst case would be updating root credentials in mc
or other clients used to administer the cluster. Root credentials
are anyway not intended for regular S3 operations.

Both are not configured by default, since we do not yet know

we should do this to ensure that we focus on
data healing as primary focus, fixing metadata

the main reason is metadata inconsistencies can
cause data availability issues, which must be
avoided at all cost.

that involves "metadata-only" heal, for now we do
not expect to have these checks.

This change makes the label names consistent with the handler names.
This is in preparation to use reflection based API handler function
names for the api labels so they will be the same as tracing, auditing
and logging names for these API calls.
Moved different dashboards to their specific directories. Also
mentioned that these dashbards are examples of how to create

Streams can return errors if the cancelation is picked up before the response
stream close is picked up. Under extreme load, this could lead to missing
responses.
Send server mux ack async so a blocked send cannot block newMuxStream
call. Stream will not progress until mux has been acked.
in k8s things really do come online very asynchronously,
we need to use implementation that allows this randomness.
To facilitate this move WriteAll() as part of the
websocket layer instead.
Bonus: avoid instances of dnscache usage on k8s
New disk healing code skips/expires objects that ILM supposed to expire.
Add more visibility to the user about this activity by calculating those
objects and print it at the end of healing activity.
This PR fixes a bug that perhaps has been long introduced,
with no visible workarounds. In any deployment, if an entire
erasure set is deleted, there is no way the cluster recovers.
Currently, if one object tag matches with one lifecycle tag filter, ILM
will select it, however, this is wrong. All the Tag filters in the
lifecycle document should be satisfied.
This change is to decouple need for root credentials to match between
site replication deployments.
Also ensuring site replication config initialization is re-tried until
it succeeds, this deoendency is critical to STS flow in site replication
scenario.
Currently, we read from `/proc/diskstats` which is found to be
un-reliable in k8s environments. We can read from `sysfs` instead.
Also, cache the latest drive io stats to find the diff and update
the metrics.
* Remove lock for cached operations.
* Rename "Relax" to `ReturnLastGood`.
* Add `CacheError` to allow caching values even on errors.
* Add NoWait that will return current value with async fetching if within 2xTTL.
* Make benchmark somewhat representative.

```
* Remove `storageRESTClient.scanning`. Nonsensical - RPC clients will not have any idea about scanning.
* Always fetch remote diskinfo metrics and cache them. Seems most calls are requesting metrics.
* Do async fetching of usage caches.
It also fixes a long-standing bug in expiring transitioned objects.
The expiration action was deleting the current version in the case'
of tiered objects instead of adding a delete marker.
only enable md5sum if explicitly asked by the client, otherwise
its not necessary to compute md5sum when SSE-KMS/SSE-C is enabled.
this is continuation of #17958
If network conditions have filled the output queue before a reconnect happens blocked sends could stop reconnects from happening. In short `respMu` would be held for a mux client while sending - if the queue is full this will never get released and closing the mux client will hang.
A) Use the mux client context instead of connection context for sends, so sends are unblocked when the mux client is canceled.
B) Use a `TryLock` on "close" and cancel the request if we cannot get the lock at once. This will unblock any attempts to send.
data-dir not being present is okay, however we can still
rely on the `rename()` atomic call instead of relying on
write xl.meta write which may truncate the io.EOF.
Add a new function logger.Event() to send the log to Console and
http/kafka log webhooks. This will include some internal events such as
disk healing and rebalance/decommissioning
the PR in #16541 was incorrect and hand wrong assumptions
about the overall setup, revert this since this expectation
to have offline servers is wrong and we can end up with a
bigger chicken and egg problem.
This reverts commit 5996c8c4d5.
Bonus:
- preserve disk in globalLocalDrives properly upon connectDisks()
- do not return 'nil' from newXLStorage(), getting it ready for
the next set of changes for 'format.json' loading.
The previous logic of calculating per second values for disk io stats
divides the stats by the host uptime. This doesn't work in k8s
environment as the uptime is of the pod, but the stats (from
/proc/diskstats) are from the host.
Fix this by storing the initial values of uptime and the stats at the
timme of server startup, and using the difference between current and
initial values when calculating the per second values.
globalLocalDrives seem to be not updated during the
HealFormat() leads to a requirement where the server
needs to be restarted for the healing to continue.

where `a/prefix` is an object which does not have `/` at the end,
we do not have to aggressively recursively delete all the sub-folders
as well. Instead convert the call into self contained to deleting
'xl.meta' and then subsequently attempting to Remove the parent.
Bonus: enable audit alerts for object versions
beyond the configured value, default is '100'
versions per object beyond which scanner will
alert for each such objects.
when we expand via pools, there is no reason to stick
with the same distributionAlgo as the rest. Since the
algo only makes sense with-in a pool not across pools.
This allows for newer pools to use newer codepaths to
avoid legacy file lookups when they have a pre-existing
deployment from 2019, they can expand their new pool
to be of a newer distribution format, allowing the
pool to be more performant.
Fix reported races that are actually synchronized by network calls.

This read will always happen after the write, since there is a network call in between.
However a disconnect could come in while we are setting up the call, so we protect against that with extra checks.
- bucket metadata does not need to look for legacy things
anymore if b.Created is non-zero
- stagger bucket metadata loads across lots of nodes to
avoid the current thundering herd problem.
- Remove deadlines for RenameData, RenameFile - these
calls should not ever be timed out and should wait
until completion or wait for client timeout. Do not
choose timeouts for applications during the WRITE phase.
- increase R/W buffer size, increase maxMergeMessages to 30
We have observed cases where a blocked stream will block for cancellations.
This happens when response channel is blocked and we want to push an error.
This will have the response mutex locked, which will prevent all other operations until upstream is unblocked.
Make this behavior non-blocking and if blocked spawn a goroutine that will send the response and close the output.
Still a lot of "dancing". Added a test for this and reviewed.
Depending on when the context cancelation is picked up the handler may return and close the channel before `SubscribeJSON` returns, causing:
```

this fixes rare bugs we have seen but never really found a
reproducer for
- PutObjectRetention() returning 503s
- PutObjectTags() returning 503s
- PutObjectMetadata() updates during replication returning 503s
These calls return errors, and this perpetuates with
no apparent fix.
This PR fixes with correct quorum requirement.
To force limit the duration of STS accounts, the user can create a new
policy, like the following:
{
"Version": "2012-10-17",
"Statement": [{
"Effect": "Allow",
"Action": ["sts:AssumeRoleWithWebIdentity"],
"Condition": {"NumericLessThanEquals": {"sts:DurationSeconds": "300"}}
}]
}
And force binding the policy to all OpenID users, whether using a claim name or role
ARN.
disk tokens usage is not necessary anymore with the implementation
of deadlines for storage calls and active monitoring of the drive
for I/O timeouts.
Functionality kicking off a bad drive is still supported, it's just that
we do not have to serialize I/O in the manner tokens would do.
Recycle would always be called on the dummy value `any(newRT())` instead of the actual value given to the recycle function.
Caught by race tests, but mostly harmless, except for reduced perf.
Other minor cleanups. Introduced in #18940 (unreleased)
Interpret `null` inline policy for access keys as inheriting parent
policy. Since MinIO Console currently sends this value, we need to honor it
for now. A larger fix in Console and in the server are required.
Fixes#18939.
Allow internal types to support a `Recycler` interface, which will allow for sharing of common types across handlers.
This means that all `grid.MSS` (and similar) objects are shared across in a common pool instead of a per-handler pool.
Add internal request reuse of internal types. Add for safe (pointerless) types explicitly.
Only log params for internal types. Doing Sprint(obj) is just a bit too messy.
With this change, only a user with `UpdateServiceAccountAdminAction`
permission is able to edit access keys.
We would like to let a user edit their own access keys, however the
feature needs to be re-designed for better security and integration with
external systems like AD/LDAP and OpenID.
This change prevents privilege escalation via service accounts.
for actionable, inspections we have `mc support inspect`
we do not need double logging, healing will report relevant
errors if any, in terms of quorum lost etc.
Each Put, List, Multipart operations heavily rely on making
GetBucketInfo() call to verify if bucket exists or not on
a regular basis. This has a large performance cost when there
are tons of servers involved.
We did optimize this part by vectorizing the bucket calls,
however its not enough, beyond 100 nodes and this becomes
fairly visible in terms of performance.
- healing must not set the write xattr
because that is the job of active healing
to update. what we need to preserve is
permanent deletes.
- remove older env for drive monitoring and
enable it accordingly, as a global value.
local disk metrics were polluting cluster metrics
Please remove them instead of adding relevant ones.
- batch job metrics were incorrectly kept at bucket
metrics endpoint, move it to cluster metrics.
- add tier metrics to cluster peer metrics from the node.
- fix missing set level cluster health metrics
Do not rely on `connChange` to do reconnects.
Instead, you can block while the connection is running and reconnect
when handleMessages returns.
Add fully async monitoring instead of monitoring on the main goroutine
and keep this to avoid full network lockup.
it is entirely possible that a rebalance process which was running
when it was asked to "stop" it failed to write its last statistics
to the disk.
After this a pool expansion can cause disruption and all S3 API
calls would fail at IsPoolRebalancing() function.
This PRs makes sure that we update rebalance.bin under such
conditions to avoid any runtime crashes.
add new update v2 that updates per node, allows idempotent behavior
new API ensures that
- binary is correct and can be downloaded checksummed verified
- committed to actual path
- restart returns back the relevant waiting drives
do not need to be defensive in our approach,
we should simply override anything everything
in import process, do not care about what
currently exists on the disk - backup is the
source of truth.
Right now the format.json is excluded if anything within `.minio.sys` is requested.
I assume the check was meant to exclude only if it was actually requesting it.
- Move RenameFile to websockets
- Move ReadAll that is primarily is used
for reading 'format.json' to to websockets
- Optimize DiskInfo calls, and provide a way
to make a NoOp DiskInfo call.
Add separate reconnection mutex
Give more safety around reconnects and make sure a state change isn't missed.
Tested with several runs of `λ go test -race -v -count=500`
Adds separate mutex and doesn't mix in the testing mutex.
AlmosAll uses of NewDeadlineWorker, which relied on secondary values, were used in a racy fashion,
which could lead to inconsistent errors/data being returned. It also propagates the deadline downstream.
Rewrite all these to use a generic WithDeadline caller that can return an error alongside a value.
Remove the stateful aspect of DeadlineWorker - it was racy if used - but it wasn't AFAICT.

Probably back from #17701
protection was in place. However, it covered only some
areas, so we re-arranged the code to ensure we could hold
locks properly.
Along with this, remove the DataShardFix code altogether,
in deployments with many drive replacements, this can affect
and lead to quorum loss.
Also limit the amount of concurrency when sending
binary updates to peers, avoid high network over
TX that can cause disconnection events for the
node sending updates.
Race checks would occasionally show race on handleMsgWg WaitGroup by debug messages (used in test only).
Use the `connMu` mutex to protect this against concurrent Wait/Add.

New API now verifies any hung disks before restart/stop,
provides a 'per node' break down of the restart/stop results.
Provides also how many blocked syscalls are present on the
drives and what users must do about them.
Adds options to do pre-flight checks to provide information
to the user regarding any hung disks. Provides 'force' option
to forcibly attempt a restart() even with waiting syscalls
on the drives.
When rejecting incoming grid requests fill out the rejection reason and log it once.
This will give more context when startup is failing. Already logged after a retry on caller.
On a policy detach operation, if there are no policies remaining
attached to the user/group, remove the policy mapping file, instead of
leaving a file containing an empty list of policies.
Healing dangling buckets is conservative, and it is a typical use case to
fail to remove a dangling bucket because it contains some data because
healing danging bucket code is not allowed to remove data: only healing
the dangling object is allowed to do so.
reference format is constant for any lifetime of
a minio cluster, we do not have to ever replace
it during HealFormat() as it will never change.
additionally we should simply reject reference
formats that we do not understand early on.
GetActualSize() was heavily relying on o.Parts()
to be non-empty to figure out if the object is multipart or not,
However, we have many indicators of whether an object is multipart
or not.
Blindly assuming that o.Parts == nil is not a multipart, is an
incorrect expectation instead, multipart must be obtained via
- Stored metadata value indicating this is a multipart encrypted object.
- Rely on <meta>-actual-size metadata to get the object's actual size.
This value is preserved for additional reasons such as these.
- ETag != 32 length
support proxying of tagging requests in active-active replication
Note: even if proxying is successful, PutObjectTagging/DeleteObjectTagging
will continue to report a 404 since the object is not present locally.
New intervals:
[1024B, 64KiB)
[64KiB, 256KiB)
[256KiB, 512KiB)
[512KiB, 1MiB)
The new intervals helps us see object size distribution with higher
resolution for the interval [1024B, 1MiB).
- HealFormat() was leaking healthcheck goroutines for
disks, we are only interested in enabling healthcheck
for the newly formatted disk, not for existing disks.
- When disk is a root-disk a random disk monitor was
leaking while we ignored the drive.
- When loading the disk for each erasure set, we were
leaking goroutines for the prepare-storage.go disks
which were replaced via the globalLocalDrives slice
- avoid disk monitoring utilizing health tokens that
would cause exhaustion in the tokens, prematurely
which were meant for incoming I/O. This is ensured
by avoiding writing O_DIRECT aligned buffer instead
write 2048 worth of content only as O_DSYNC, which is
sufficient.
Add a hidden configuration under the scanner sub section to configure if
the scanner should sleep between two objects scan. The configuration has
only effect when there is no drive activity related to s3 requests or
healing.
By default, the code will keep the current behavior which is doing
sleep between objects.
To forcefully enable the full scan speed in idle mode, you can do this:
`mc admin config set myminio scanner idle_speed=full`

SUBNET now has a v2 of license that is returned in the new key

`(*xlStorageDiskIDCheck).CreateFile` wraps the incoming reader in `xioutil.NewDeadlineReader`.
The wrapped reader is handed to `(*xlStorage).CreateFile`. This performs a Read call via `writeAllDirect`,
which reads into an `ODirectPool` buffer.
`(*DeadlineReader).Read` spawns an async read into the buffer. If a timeout is hit while reading,
the read operation returns to `writeAllDirect`. The operation returns an error and the buffer is reused.
However, if the async `Read` call unblocks, it will write to the now recycled buffer.
Fix: Remove the `DeadlineReader` - it is inherently unsafe. Instead, rely on the network timeouts.
This is not a disk timeout, anyway.
Regression in https://github.com/minio/minio/pull/17745
This patch adds the targetID to the existing notification target metrics
and deprecates the current target metrics which points to the overall
event notification subsystem
historically, we have always kept storage-rest-server
and a local storage API separate without much trouble,
since they both can independently operate due to no
special state() between them.
however, over some time, we have added state()
such as
- drive monitoring threads now there will be "2" of
them per drive instead of just 1.
- concurrent tokens available per drive are now twice
instead of just single shared, allowing unexpectedly
high amount of I/O to go through.
- applying serialization by using walkMutexes can now
be adequately honored for both remote callers and local
callers.
Regression from #18285. CopyObject options were inheriting source MTime
for metadata timestamps if unspecified, removing this prevented metadata
updates from being applied on target.
The metrics `minio_bucket_replication_received_bytes` and
`minio_bucket_replication_sent_bytes` are additive in nature
and rendering the value as is looks fine.
Also added sort order for few graphs for better reading of tool
tips as keeping ones with highest value at top helps.

moveToTrash() function moves a folder to .trash, for example, when

This allows batch replication to basically do not
attempt to copy objects that do not have read quorum.
This PR also allows walk() to provide custom

This is to basically disable all pre-signed URLs that are older than 10 minutes.
AWS S3 closes keep-alive connections frequently
leading to frivolous logs filling up the MinIO

Ignore such transient errors, let MinIO retry

When minio runs with MINIO_CI_CD=on, it is expected to communicate
with the locally running SUBNET. This is happening in the case of MinIO
via call home functionality. However, the subnet-related functionality inside the
console continues to talk to the SUBNET production URL. Because of this,
the console cannot be tested with a locally running SUBNET.
Set the env variable CONSOLE_SUBNET_URL correctly in such cases.
(The console already has code to use the value of this variable
as the subnet URL)
Optionally allows customers to enable
- Enable an external cache to catch GET/HEAD responses
- Enable skipping disks that are slow to respond in GET/HEAD

Bonus: allow replication to attempt Deletes/Puts when

to ensure that MinIO can rewrite the namespace with the
latest version that exists on the source.
This PR adds a WebSocket grid feature that allows servers to communicate via
a single two-way connection.
There are two request types:
* Single requests, which are `[]byte => ([]byte, error)`. This is for efficient small
roundtrips with small payloads.
* Streaming requests which are `[]byte, chan []byte => chan []byte (and error)`,
which allows for different combinations of full two-way streams with an initial payload.
Only a single stream is created between two machines - and there is, as such, no
server/client relation since both sides can initiate and handle requests. Which server
initiates the request is decided deterministically on the server names.
Requests are made through a mux client and server, which handles message
passing, congestion, cancelation, timeouts, etc.
If a connection is lost, all requests are canceled, and the calling server will try
to reconnect. Registered handlers can operate directly on byte
slices or use a higher-level generics abstraction.
There is no versioning of handlers/clients, and incompatible changes should
be handled by adding new handlers.
The request path can be changed to a new one for any protocol changes.
First, all servers create a "Manager." The manager must know its address
as well as all remote addresses. This will manage all connections.
To get a connection to any remote, ask the manager to provide it given
the remote address using.
```
func (m *Manager) Connection(host string) *Connection
```
All serverside handlers must also be registered on the manager. This will
make sure that all incoming requests are served. The number of in-flight
requests and responses must also be given for streaming requests.
The "Connection" returned manages the mux-clients. Requests issued
to the connection will be sent to the remote.
* `func (c *Connection) Request(ctx context.Context, h HandlerID, req []byte) ([]byte, error)`
performs a single request and returns the result. Any deadline provided on the request is
forwarded to the server, and canceling the context will make the function return at once.
* `func (c *Connection) NewStream(ctx context.Context, h HandlerID, payload []byte) (st *Stream, err error)`
will initiate a remote call and send the initial payload.
```Go
// A Stream is a two-way stream.
// All responses *must* be read by the caller.
// If the call is canceled through the context,
//The appropriate error will be returned.
type Stream struct {
// Responses from the remote server.
// Channel will be closed after an error or when the remote closes.
// All responses *must* be read by the caller until either an error is returned or the channel is closed.
// Canceling the context will cause the context cancellation error to be returned.
Responses <-chan Response
// Requests sent to the server.
// If the handler is defined with 0 incoming capacity this will be nil.
// Channel *must* be closed to signal the end of the stream.
// If the request context is canceled, the stream will no longer process requests.
Requests chan<- []byte
}
type Response struct {
Msg []byte
Err error
}
```
There are generic versions of the server/client handlers that allow the use of type
safe implementations for data types that support msgpack marshal/unmarshal.
With an odd number of drives per erasure set setup, the write/quorum is

Immediate transition use case and is mostly used to fill warm
backend with a lot of data when a new deployment is created
Currently, if the transition queue is complete, the transition will be
deferred to the scanner; change this behavior by blocking the PUT request
until the transition queue has a new place for a transition task.
Currently, once the audit becomes offline, there is no code that tries
to reconnect to the audit, at the same time Send() quickly returns with
an error without really trying to send a message the audit endpoint; so
the audit endpoint will never be online again.
Fixing this behavior; the current downside is that we miss printing some
logs when the audit becomes offline; however this information is
available in prometheus
Later, we can refactor internal/logger so the http endpoint can send errors to
console target.
Currently if the object does not exist in quorum disks of an erasure
set, the dangling code is never called because the returned error will
be errFileNotFound or errFileVersionNotFound;
With this commit, when errFileNotFound or errFileVersionNotFound is
returning when trying to calculate the quorum of a given object, the
code checks if a disk returned nil, which means a stale object exists in
that disk, that will trigger deleteIfDangling() function
This commit splits the liveness and readiness
handler into two separate handlers. In K8S, a
liveness probe is used to determine whether the
pod is in "live" state and functioning at all.
In contrast, the readiness probe is used to
determine whether the pod is ready to serve
requests.
A failing liveness probe causes pod restarts while
a failing readiness probe causes k8s to stop routing
traffic to the pod. Hence, a liveness probe should
be as robust as possible while a readiness probe
should be used to load balancing.

sendfile implementation to perform DMA on all platforms
Go stdlib already supports sendfile/splice implementations
for
- Linux
- Windows
- *BSD
- Solaris
Along with this change however O_DIRECT for reads() must be
removed as well since we need to use sendfile() implementation
The main reason to add O_DIRECT for reads was to reduce the
chances of page-cache causing OOMs for MinIO, however it would
seem that avoiding buffer copies from user-space to kernel space
this issue is not a problem anymore.
There is no Go based memory allocation required, and neither
the page-cache is referenced back to MinIO. This page-
cache reference is fully owned by kernel at this point, this
essentially should solve the problem of page-cache build up.

remote targets go AWOL.
resync status may not be upto-date by

This is primarily to handle a case where a policy mapping update

have the stale mapping in memory because STS creds/mappings were never
periodically scanned from storage.

AccountInfo is quite frequently called by the Console UI

- Bucket usage info is cached for up to 10 seconds
- Prefix usage (optional) info is cached for up to 10 secs
Failure to update after cache expiration, would still
allow login which would end up providing information
previously cached.
This allows for seamless responsiveness for the Console UI
logins, and overall responsiveness on a heavily loaded

When using a chain provider all providers do not return a valid
access and secret key, an anonymous request is sent, which makes it hard
for users to figure out what is going on
In the case of S3 tiering, when AWS IAM temporary account generation returns
an error, an anonymous login will be used because of the chain provider.
Avoid this and use the AWS IAM provider directly to get a good error
message.
This helps reduce disk operations as these periodic routines would not
run concurrently any more.
Also add expired STS purging periodic operation: Since we do not scan
the on-disk STS credentials (and instead only load them on-demand) a
separate routine is needed to purge expired credentials from storage.
Currently this runs about a quarter as often as IAM refresh.
Also fix a bug where with etcd, STS accounts could get loaded into the
iamUsersMap instead of the iamSTSAccountsMap.
This allows scanner to avoid lengthy scans, skip
things appropriately and also not lose metrics in
any manner.
reduce longer deadlines for usage-cache loads/saves
to match the disk timeout which is 2minutes now per
IOP.
In situations with large number of STS credentials on disk, IAM load
time is high. To mitigate this, STS accounts will now be loaded into
memory only on demand - i.e. when the credential is used.
In each IAM cache (re)load we skip loading STS credentials and STS
policy mappings into memory. Since STS accounts only expire and cannot
be deleted, there is no risk of invalid credentials being reused,
because credential validity is checked when it is used.
Currently we have IOPs of these patterns
```

Fix drive rotational calculation status
If a MinIO drive path is mounted to a partition and not a real disk,
getting the rotational status would fail because Linux does not expose
that status to partition; In other words,
/sys/block/drive-partition-name/queue/rotational does not exist;
To fix the issue, the code will search for the rotational status of the
disk that hosts the partition, and this can be calculated from the
real path of /sys/class/block/<drive-partition-name>

There is some consistent confusion between the Community Helm Chart in this repo and the MinIO Kubernetes Operator Helm Chart.
This change seeks to clarify the differences between the two charts and which ones are community maintained vs MinIO maintained.

Send() is synchronous and can affect the latency of S3 requests when the

Avoid checking if the HTTP target is online or not and increase the

Also, avoid logs flooding when the audit target is down.
Limit large uploads (> 128MiB) to a max of 10 workers, intent is to avoid
larger uploads from using all replication bandwidth, giving room for smaller

Revert "don't error when asked for 0-based range on empty objects (#17708)"
This reverts commit 7e76d66184.
There is no valid way to specify offsets in a 0-byte file. Blame it on the [RFC](https://datatracker.ietf.org/doc/html/rfc7233#section-4.4)
> The 416 (Range Not Satisfiable) status code indicates that none of the ranges in the
> request's Range header field (Section 3.1) overlap the current extent of the selected resource...
A request for "bytes=0-" is a request for the first byte of a resource. If the resource is 0-length,
the range [0,0] does not overlap the resource content and the server responds with an error.
In a reverse proxying setup, a proxy in front of MinIO may attempt to
request objects in slices for enhanced cache efficiency. Since such a
a proxy cannot have prior knowledge of how large a requested resource is,
it usually sends a header of the form:
Range: 0-$slice_size
... and, depending on the size of the resource, expects either:
- an empty response, if $resource_size == 0
- a full response, if $resource_size <= $slice_size
- a partial response, if $resource_size > $slice_size
Prior to this change, MinIO would respond 416 Range Not Satisfiable if a
client tried to request a range on an empty resource. This behavior is
technically consistent with RFC9110[1] – However, it renders sliced
reverse proxying, such as implemented in Nginx, broken in the case of
empty files. Nginx itself seems to break this convention to enable
"useful" responses in these cases, and MinIO should probably do that
too.
[1]: https://www.rfc-editor.org/rfc/rfc9110#byte.ranges
sending whitespace character with CompleteMultipartUpload()
with 200 OK was an AWS S3 compatible implementation detail,
and it was expected that the client SDK must look for both
successful XML as well as error XML for 200 OK.
But this is not useful anymore on MinIO, since we do not
have any large delayed coalescing of parts anymore.
users/customers do not have a reasonable number of buckets anymore,
this is why we must avoid overpopulating cluster endpoints, instead
move the bucket monitoring to a separate endpoint.
some of it's a breaking change here for a couple of metrics, but
it is imperative that we do it to improve the responsiveness of
our Prometheus cluster endpoint.
Bonus: Added new cluster metrics for usage, objects and histograms

Sometimes IAM fails to load certain items, which could be a user,
a service account or a policy but with not enough information for
us to debug.
This commit will create a more descriptive error to make it easier to

objects/versions that are not expired via NewerNoncurrentVersions
must be properly returned to be applied under further ILM actions.
this would cause legitimately expired objects to be missed
from expiration.
this randomness is needed to avoid scanning

in the same order.

allowing a wider spread of ILM, replication
checks.
Additionally do not loop over twice to fill

A new middleware function is added for admin handlers, including options
for modifying certain behaviors. This admin middleware:
- sets the handler context via reflection in the request and sends AuditLog
- checks for object API availability (skipping it if a flag is passed)
- enables gzip compression (skipping it if a flag is passed)
- enables header tracing (adding body tracing if a flag is passed)
While the new function is a middleware, due to the flags used for
conditional behavior modification, which is used in each route registration
call.
To try to ensure that no regressions are introduced, the following
changes were done mechanically mostly with `sed` and regexp:
- Remove defer logger.AuditLog in admin handlers
- Replace newContext() calls with r.Context()
- Update admin routes registration calls
Bonus: remove unused NetSpeedtestHandler
Since the new adminMiddleware function checks for object layer presence
by default, we need to pass the `noObjLayerFlag` explicitly to admin
handlers that should work even when it is not available. The following
admin handlers do not require it:
- ServerInfoHandler
- StartProfilingHandler
- DownloadProfilingHandler
- ProfileHandler
- SiteReplicationDevNull
- SiteReplicationNetPerf
- TraceHandler
For these handlers adminMiddleware does not check for the object layer
presence (disabled by passing the `noObjLayerFlag`), and for all other
handlers, the pre-check ensures that the handler is not called when the
object layer is not available - the client would get a
ErrServerNotInitialized and can retry later.
This `noObjLayerFlag` is added based on existing behavior for these
handlers only.
Add check every 2 minutes to see if a write+read operation can complete.
If disk is unresponsive for 2 minutes or returns errFaultyDisk, take it offline.
Simplify MRF queueing and add backlog handler
- Limit re-tries to 3 to avoid repeated re-queueing. Fall offs

- Change MRF to have each node process only its MRF entries.
- Collect MRF backlog by the node to allow for current backlog visibility

It can be observed how now restarting the service is
much snappier.

one-way replication or when replication was disabled).
In such cases, mark version purge complete.
Since `addCustomerHeaders` middleware was after the `httpTracer`
middleware, the request ID was not set in the http tracing context. By
reordering these middleware functions, the request ID header becomes
available. We also avoid setting the tracing context key again in
`newContext`.
Bonus: All middleware functions are renamed with a "Middleware" suffix
to avoid confusion with http Handler functions.

For policy attach/detach API to work correctly the server should hold a

Bonus: Additionally, the server responds with the actual (or net)

performed, the server will respond that B was attached successfully.
A continuation of PR #17479 for rebalance behavior must

Fixes bug where rebalance would ignore rebalancing object
versions after one of the version returned "ObjectNotFound"
while decommissioning it can so happen that the non-current
versions are all expired but there is a DEL marker as the
latest version.
For such objects, we should not decommission them instead
calculate the remaining versions and if the remaining versions
is one and that version is a DEL marker consider such
an object not to be scheduled for decommissioning.
With the current asynchronous behaviour in sending notification events
to the targets, we can't provide guaranteed delivery as the systems
might go for restarts.
For such event-driven use-cases, we can provide an option to enable
synchronous events where the APIs wait until the event is successfully
sent or persisted.
This commit adds 'MINIO_API_SYNC_EVENTS' env which when set to 'on'
will enable sending/persisting events to targets synchronously.
A state is updated with a delete marker, which does not have parity or

an inconsistent state() with mtime while the

and if etag matches we are guaranteed that we

PUT calls cannot afford to have large latency build-ups due
to contentious usage.json, or worse letting them fail with
some unexpected error, this can happen when this file is
concurrently being updated via scanner or it is being
healed during a disk replacement heal.
However, these are fairly quick in theory, stressed clusters
can quickly show visible latency this can add up leading to
invalid errors returned during PUT.
It is perhaps okay for us to relax this error return requirement
instead, make sure that we log that we are proceeding to take in
the requests while the quota is using an older value for the quota
enforcement. These things will reconcile themselves eventually,
via scanner making sure to overwrite the usage.json.
Bonus: make sure that storage-rest-client sets ExpectTimeouts to
be 'true', such that DiskInfo() call with contextTimeout does
not prematurely disconnect the servers leading to a longer
healthCheck, back-off routine. This can easily pile up while also
causing active callers to disconnect, leading to quorum loss.
DiskInfo is actively used in the PUT, Multipart call path for
upgrading parity when disks are down, it in-turn shouldn't cause
more disks to go down.
Removes the bloom filter since it has so limited usability, often gets saturated anyway and adds a bunch of complexity to the scanner.
Also removes a tiny bit of CPU by each write operation.
Global leader lock was first designated to only acquired once
until the node is killed. However, currently, the code acquires
it repeatedly during the lifetime of the server, now there is a
goroutine leak.
if the certs are the same in an environment where the
cert files are symlinks (e.g Kubernetes), then we resort
to reloading certs every 15mins - we can avoid reload

for contending with the lock must happen when necessary.
remote error is not required to be passed back to the
client - this is mostly because we have healing that should
eventually, catch up on this and heal the bucket.
Ensure delete marker replication success, especially since the
recent optimizations to heal on HEAD, LIST and GET can force
replication attempts on delete marker before underlying object
version could have synced.
Move to using `xl.meta` data structure to keep temporary partInfo,
this allows for a future change where we move to different parts to
different drives.
PUT shall only proceed if pre-conditions are met, the new
code uses

to verify if the object indeed needs to be replicated
or not, allowing us to avoid StatObject() call.

Theory: Both objects are written with the same timestamp due to lower timer resolution on Windows. This results in secondary resolution, which is deterministic, but random.
Solution: Instead of hacking in a wait we request the specific version we want. Should still keep the test relevant.
Bonus: Remote action dependency for vulncheck
If replication config could not be read from bucket metadata for some
reason, issue a panic so that unexpected replication outcomes can
be avoided for replicated buckets.
For similar reasons, adding a panic while fetching object-lock config

to avoid relying on scanner-calculated replication metrics.
This will improve the accuracy of the replication stats reported.
This PR also adds on to #15556 by handing replication
traffic that could not be queued by available workers to the
MRF queue so that entries in `PENDING` status are healed faster.
500k is a reasonable limit for any single MinIO
cluster deployment, in future we may increase this
value.
However for now we are going to keep this limit.
When healing is parallelized by setting the ` _MINIO_HEAL_WORKERS`
environment variable, multiple goroutines may race while updating the disk's
healing tracker. This change serializes only these concurrent updates using a
channel. Note, the healing tracker is still not concurrency safe in other contexts.
This PR is a continuation of the previous change instead
of returning an error, instead trigger a spot heal on the
'xl.meta' and return only after the healing is complete.
This allows for future GETs on the same resource to be
consistent for any version of the object.
xl.meta gets written and never rolled back, however
we definitely need to validate the state that is
persisted on the disk, if there are inconsistencies
- more than write quorum we should return an error
to the client
- if write quorum was achieved however there are
inconsistent xl.meta's we should simply trigger
an MRF on them
The `clusterInfo` struct in admin-handlers is same as
madmin.ClusterRegistrationInfo, except for small differences in field
names.
Removing this and using madmin.ClusterRegistrationInfo in its place will
help in following ways:
- The JSON payload generated by mc in case of cluster registration will
be consistent (same keys) with cluster.info generated by minio as part
of the profile and inspect zip
- health-analyzer can parse the cluster.info using the same struct and
won't have to define it's own
Currently, there is a short time window where the code is allowed
to save the status of a replication resync. Currently, the window is
`now.Sub(st.EndTime) <= resyncTimeInterval`. Also, any failure to
write in the backend disks is not retried.
Refactor the code a little bit to rely on the last timestamp of a
successful write of the resync status of any given bucket in the
backend disks.
When replication is enabled in a particular bucket, the listing will send
objects to bucket replication, but it is also sending prefixes for non
recursive listing which is useless and shows a lot of error logs.
This commit will ignore prefixes.

A lot of warning messages are printed in CI/CD failures generated by go
test. Avoid that by requiring at least Error level for logging when
doing go test.
inlined data often is bigger than the allowed
O_DIRECT alignment, so potentially we can write
'xl.meta' without O_DSYNC instead we can rely on
O_DIRECT + fdatasync() instead.
This PR allows O_DIRECT on inlined data that
would gain the benefits of performing O_DIRECT,
eventually performing an fdatasync() at the end.
Performance boost can be observed here for small
objects < 128KiB. The performance boost is mainly
seen on HDD, and marginal on NVMe setups.

When a node finds a change in the other replication cluster and applies
to itself will already notify other peers. No need for all nodes in a
given cluster to do site replication healing, only one node is
sufficient.
This PR improves the replication failure healing by persisting
most recent failures to disk and re-queuing them until the replication
is successful.
While this does not eliminate the need for healing during a full scan,
queuing MRF vastly improves the ETA to keeping replicated buckets
in sync as it does not wait for the scanner visit to detect unreplicated
object versions.
competing calls on the same object on versioned bucket
mutating calls on the same object may unexpected have
higher delays.
This can be reproduced with a replicated bucket
overwriting the same object writes, deletes repeatedly.
For longer locks like scanner keep the 1sec interval
This PR fixes possible leaks that may emanate from not
listening on context cancelation or timeouts.

The bottom line is delete markers are a nuisance,
most applications are not version aware and this
has simply complicated the version management.
AWS S3 gave an unnecessary complication overhead
for customers, they need to now manage these
markers by applying ILM settings and clean
them up on a regular basis.
To make matters worse all these delete markers
get replicated as well in a replicated setup,
requiring two ILM settings on each site.
This PR is an attempt to address this inferior
implementation by deviating MinIO towards an
idempotent delete marker implementation i.e
MinIO will never create any more than single
consecutive delete markers.
This significantly reduces operational overhead
by making versioning more useful for real data.
This is an S3 spec deviation for pragmatic reasons.
Queue failed/pending replication for healing during listing and GET/HEAD
API calls. This includes healing of existing objects that were never
replicated or those in the middle of a resync operation.
This PR also fixes a bug in ListObjectVersions where lifecycle filtering

The path is marked dirty automatically when healObject() is called, which is
wrong. HealObject() is called during self-healing and this will lead to
an increase in the false positive result of the bloom filter.
Also move NSUpdated() from renameData() and call it directly in
CompleteMultipart and PutObject, this is not a functional change but
it will make it less prone to errors in the future.

This PR changes the handling of bucket deletes for site
replicated setups to hold on to deleted bucket state until
it syncs to all the clusters participating in site replication.
Currently, if one server in a distributed setup fails to upgrade
due to any reasons, it is not possible to upgrade again unless
nodes are restarted.
To fix this, split the upgrade process into two steps :
- download the new binary on all servers
- If successful, overwrite the old binary with the new one
This commit replaces `ioutil.TempDir` with `t.TempDir` in tests. The
directory created by `t.TempDir` is automatically removed when the test
and all its subtests complete.
Prior to this commit, temporary directory created using `ioutil.TempDir`
needs to be removed manually by calling `os.RemoveAll`, which is omitted
in some tests. The error handling boilerplate e.g.
defer func() {
if err := os.RemoveAll(dir); err != nil {
t.Fatal(err)
}
}
is also tedious, but `t.TempDir` handles this for us nicely.

Add cluster info to inspect and profiling archive.

a/b/c/d/ where `a/b/c/` exists results in additional syscalls
such as an Lstat() call to verify if the `a/b/c/` exists
and its a directory.
We do not need to do this on MinIO since the parent prefixes
if exist, we can simply return success without spending
additional syscalls.
Also this implementation attempts to simply use Access() calls
to avoid os.Stat() calls since the latter does memory allocation
for things we do not need to use.
Access() is simpler since we have a predictable structure on
the backend and we know exactly how our path structures are.

Do completely independent multipart uploads.
In distributed mode, a lock was held to merge each multipart
upload as it was added. This lock was highly contested and
retries are expensive (timewise) in distributed mode.
Instead, each part adds its metadata information uniquely.
This eliminates the per object lock required for each to merge.
The metadata is read back and merged by "CompleteMultipartUpload"
without locks when constructing final object.

Uploading a part object can leave an inconsistent state inside
.minio.sys/multipart where data are uploaded but xl.meta is not
committed yet.
Do not list upload-ids that have this state in the multipart listing.
The default replica value is 16 (right now) which can lead to massive
resource consumption on one node in smaller clusters. The idea for this
addition is to allow users to specify how the pods (replicas) are being
spread across the cluster. It gives more control over this Helm Release
in smaller clusters where most worker nodes have taints.
As this Kubernetes feature exists since Kubernetes 1.19 and is only
useful for a replica count > 1, this was taken into account.
Since this is a MinIO specific extension in the replication config,
default this to Disabled to allow other sdks to be used to configure
replication rules.

Use losetup to create fake disks, start a MinIO cluster, umount
one disk, and fails if the mount point directory will have format.json
recreated. It should fail because the mount point directory will belong
to the root disk after unmount.
Add up to 256 bytes of padding for compressed+encrypted files.
This will obscure the obvious cases of extremely compressible content
and leave a similar output size for a very wide variety of inputs.
This does *not* mean the compression ratio doesn't leak information
about the content, but the outcome space is much smaller,
so often *less* information is leaked.
Make bucket requests sent after decommissioning is started are not
created in a suspended pool. Therefore listing buckets should avoid
suspended pools as well.
Rename Trigger -> Event to be a more appropriate
name for the audit event.
Bonus: fixes a bug in AddMRFWorker() it did not
cancel the waitgroup, leading to waitgroup leaks.
There is no point in compressing very small files.
Typically the effective size on disk will be the same due to disk blocks.
So don't waste resources on extremely small files.
We don't check on multipart. 1) because we don't know and 2) this is very likely a big object anyway.

If more than 1M folders (objects or prefixes) are found at the top level in a bucket allow it to be compacted.

GetDiskInfo() uses timedValue to cache the disk info for one second.
timedValue behavior was recently changed to return an old cached value
when calculating a new value returns an error.
When a mount point is empty, GetDiskInfo() will return errUnformattedDisk,
timedValue will return cached disk info with unexpected IsRootDisk value,
e.g. false if the mount point belongs to a root disk. Therefore, the mount
point will be considered a valid disk and will be formatted as well.
This commit will also add more defensive code when marking root disks:
always mark a disk offline for any GetDiskInfo() error except
errUnformattedDisk. The server will try anyway to reconnect to those
disks every 10 seconds.

delete's are okay to be allowed since decommission is

site replication errors were printed at

capture all of them at a common place.
This PR also enhances the code to show
partial success and errors as well.
`mc admin heal -r <alias>` in a multi setup pools returns incorrectly
grey objects. The reason is that erasure-server-pools.HealObject() runs
HealObject in all pools and returns the result of the first nil
error. However, in the lower erasureObject level, HealObject() returns
nil if an object does not exist + missing error in each disk of the object
in that pool, therefore confusing mc.
Make erasureObject.HealObject() to return not found error in the lower
level, so at least erasureServerPools will know what pools to ignore.
`config.ResolveConfigParam` returns the value of a configuration for any
subsystem based on checking env, config store, and default value. Also returns info
about which config source returned the value.
This is useful to return info about config params overridden via env in the user
APIs. Currently implemented only for OpenID subsystem, but will be extended for
others subsequently.
If sending a white space during a long S3 handler call fails,
the whitespace goroutine forgets to return a result to the caller.
Therefore, the complete multipart handler will be blocked.
Remember to send the header written result to the caller
or/and close the channel.

this allows for customers to use `mc admin service restart`

after upgrade MinIO will re-read the /etc/default/minio for any
newer environment variables.
As long as `MINIO_CONFIG_ENV_FILE=/etc/default/minio` is set, this
is honored.
Currently minio_s3_requests_errors_total covers 4xx and
5xx S3 responses which can be confusing when s3 applications
sent a lot of HEAD requests with obvious 404 responses or
when the replication is enabled.
Add
- minio_s3_requests_4xx_errors_total
- minio_s3_requests_5xx_errors_total
to help users monitor 4xx and 5xx HTTP status codes separately.
peerOnlineCounter was making NxN calls to many peers, this
can be really long and tedious if there are random servers
that are going down.
Instead we should calculate online peers from the point of
view of "self" and return those online and offline appropriately
by performing a healthcheck.
The 'go mod vendor' command generates a directory called
'vendor' in the main module's root directory, which includes
the required packages to support builds. Therefore, we can
include the 'vendor' directory in .gitignore completely,

PR #15041 fixed replicating 'null' version however
due to a regression from #14994 caused the target

bi-directional replication and cause double replication.
This PR fixes this properly by making sure we replicate
the correct versions on the objects.
mergeEntryChannels has the potential to perpetually
wait on the results channel, context might be closed
and we did not honor the caller context canceling.
The S3 service can be frozen indefinitely if a client or mc asks for object
perf API but quits early or has some networking issues. The reason is
that partialWrite() can block indefinitely.
This commit makes partialWrite() listens to context cancellation as well. It
also renames deadlinedCtx to healthCtx since it covers handler context
cancellation and not only not only the speedtest deadline.
In a streaming response, the client knows the size of a streamed
message but never checks the message size. Add the check to error
out if the response message is truncated.
Indexed streams would be decoded by the legacy loader if there
was an error loading it. Return an error when the stream is indexed
and it cannot be loaded.
Fixes "unknown minor metadata version" on corrupted xl.meta files and
returns an actual error.
We need to make sure if we cannot read bucket metadata
for some reason, and bucket metadata is not missing and
returning corrupted information we should panic such

readAllXL would return inlined data for outdated disks
causing "read" to return incorrect content to the client,
this PR fixes this behavior by making sure we skip such
outdated disks appropriately based on the latest ModTime
on the disk.
Main motivation is move towards a common backend format
for all different types of modes in MinIO, allowing for
a simpler code and predictable behavior across all features.
This PR also brings features such as versioning, replication,
transitioning to single drive setups.
Following code can reproduce an unending go-routine buildup,
while keeping connections established due to lack of client
not closing the connections.

Without this PR all MinIO deployments can be put into
denial of service attacks, causing entire service to be
unavailable.
We bring in two timeouts at this stage to control such
go-routine build ups, new change
- IdleTimeout (to kill off idle connections)
- ReadHeaderTimeout (to kill off connections that are too slow)
This new change also brings two hidden options to make any
additional relevant changes if desired in some setups.
It would seem like the PR #11623 had chewed more
than it wanted to, non-fips build shouldn't really
be forced to use slower crypto/sha256 even for
presumed "non-performance" codepaths. In MinIO
there are really no "non-performance" codepaths.
This assumption seems to have had an adverse
effect in certain areas of CPU usage.
This PR ensures that we stick to sha256-simd
on all non-FIPS builds, our most common build
to ensure we get the best out of the CPU at
any given point in time.

this PR also fixes a situation where incorrect
partsMetadata slice was used where fi.Data was
re-used from a single drive causing duplication
of the shards across all drives.
This happens for situations where shouldHeal()
returns true for all drives > parityBlocks.
To avoid this we should never attempt to heal on all
drives > parityBlocks, unless we are doing metadata

If one or more pools reach 85% usage in a set, we will only
use pools that have more free space.
In case all pools are above 85% we allow all of them to be used
with the regular distribution.
When a server pool with a different number of sets is added they are
not compensated when choosing a destination pool for new objects.
This leads to the unbalanced placement of objects with smaller pools
getting a bigger number of objects since we only compare the destination
sets directly.
This change will compensate for differences in set sizes when choosing
the destination pool.
Different set sizes are already compensated by fewer disks.
updating metadata with CopyObject on a versioned bucket
causes the latest version to be not readable, this PR fixes
this properly by handling the inline data bug fix introduced
in PR #14780.
This bug affects only inlined data.
* Do not use inline data size in xl.meta quorum calculation
Data shards of one object can different inline/not-inline decision
in multiple disks. This happens with outdated disks when inline
decision changes. For example, enabling bucket versioning configuration
will change the small file threshold.
When the parity of an object becomes low, GET object can return 503
because it is not unable to calculate the xl.meta quorum, just because
some xl.meta has inline data and other are not.
So this commit will be disable taking the size of the inline data into
consideration when calculating the xl.meta quorum.
* Add tests for simulatenous inline/notinline object

current implementation relied on recursively calling one bucket

when there are 100's of buckets which would mean 100*peerCount
amount of network operations.
This PR attempts to reduce this entire call into `peerCount`
amount of network calls only. This functionality addresses also a
concern where the Prometheus metrics would significantly slow
down when one of the peers is offline.

If LDAP is enabled, STS security token policy is evaluated using a
different code path and expects ldapUser claim to exist in the security
token. This means other STS temporary accounts generated by any Assume
Role function, such as AssumeRoleWithCertificate, won't be allowed to do any
operation as these accounts do not have LDAP user claim.
Since IsAllowedLDAPSTS() is similar to IsAllowedSTS(), this commit will
merge both.
Non harmful changes:
- IsAllowed for LDAP will start supporting RoleARN claim
- IsAllowed for LDAP will not check for parent claim anymore. This check doesn't
seem to be useful since all STS login compare access/secret/security-token
with the one saved in the disk.
- LDAP will support $username condition in policy documents.

anything that is stuck on the disk today can cause latency
spikes for all incoming S3 I/O, we need to have this
de-coupled so that we can make sure that latency in loading
credentials are not reflected back to the S3 API calls.
The approach this PR takes is by checking if the calls were
updated just in case when the IAM load was in progress,
so that we can use merge instead of "replacement" to avoid
missing state.
When configuring a new target, such as an audit target, the server waits
until all audit events are sent to the audit target before doing the
swap from the old to the new audit target. Therefore current S3 operations
can suffer from this since the audit swap lock will be held.
This behavior is unnecessary as the new audit target can enter in a
functional mode immediately and the old audit will just cancel itself
at its own pace.
Object tags can have special characters such as whitespace. However
the current code doesn't properly consider those characters while

The test expects from DeleteFile to return errDiskNotFound when the disk
is not available. It calls os.RemoveAll() to remove one disk after XL storage
initialization. However, this latter contains some goroutines which can
race with os.RemoveAll() and then the test fails sporadically with
returning random errors.
The commit will tweak the initialization routine of the XL storage to
only run deletion of temporary and metacache data in the background,
so TestXLStorageDeleteFile won't fail anymore.
currently, we allowed buckets to be listed from the
API call if and when the user has ListObject()
permission at the global level, this is okay to be
extended to GetBucketLocation() as well since
GetBucketLocation() is a "read" call and allowing "reads"
on a bucket has an implicit assumption that ListBuckets()
should be allowed.
This makes discoverability of access for read-only users
becomes easier or users with specific restrictions on their
policies.

PR #14828 introduced prefix-level exclusion of versioning

temporary prefix in a bucket. These objects are
'renamed' to a different prefix on Job commit.
Object storage admins are forced to configure
separate ILM policies to expire these objects
and their versions to reclaim space.
Our solution:
This can be avoided by simply marking objects
under these prefixes to be excluded from versioning,
as shown below. Consequently, these objects are
excluded from replication, and don't require ILM
policies to prune unnecessary versions.

<ExcludedPrefixes>
<Prefix>app2-jobs/*/__magic/</Prefix>
</ExcludedPrefixes>
<!-- .. up to 10 prefixes in all -->

```
Note: `ExcludeFolders` excludes all folders in a bucket
from versioning. This is required to prevent the parent
folders from accumulating delete markers, especially
those which are shared across spark workloads
spanning projects/teams.

instead of base64 equivalent on the disk.
- relax requirements for Deleting a service account, allow

The site replication status call was using a loop iteration variable sent
directly into go-routines instead of being passed as an argument. As the
variable is being updated in the loop, previously launched go routines do not
necessarily use the value at the time they were launched.
This PR fixes two issues
- The first fix is a regression from #14555, the fix itself in #14555
is correct but the interpretation of that information by the
object layer code for "replication" was not correct. This PR
tries to fix this situation by making sure the "Delete" replication
works as expected when "VersionPurgeStatus" is already set.
Without this fix, there is a DELETE marker created incorrectly on
the source where the "DELETE" was triggered.
- The second fix is perhaps an older problem started since we inlined-data
on the disk for small objects, CopyObject() incorrectly inline's
a non-inlined data. This is due to the fact that we have code where
we read the `part.1` under certain conditions where the size of the
`part.1` is less than the specific "threshold".
This eventually causes problems when we are "deleting" the data that
is only inlined, which means dataDir is ignored leaving such
dataDir on the disk, that looks like an inconsistent content on
the namespace.

It is wasteful to allow parallel upgrades of MinIO server. This also generates
weird error invoked by selfupdate module when it happens such as:
'rename /opt/bin/.minio.old /opt/bin/..minio.old.old'
currently filterPefix was never used and set
that would filter out entries when needed
when `prefix` doesn't end with `/` - this
often leads to objects getting Walked(), Healed()
that were never requested by the caller.
without this wait there is a potential for some objects
that are in actively being decommissioned would cancel,
however the decommission status might wrongly conclude
this as "Complete".
To avoid this make sure to add waitgroups on the parallel
workers, allowing parallel copies to complete fully before
we return.

This commit adds two new functions to the
internal `etag` package:
- `ETag.Format`
- `Decrypt`
The `Decrypt` function decrypts an encrypted
ETag using a decryption key. It returns not
encrypted / multipart ETags unmodified.
The `Decrypt` function is mainly used when
handling SSE-S3 encrypted single-part objects.
In particular, the ETag of an SSE-S3 encrypted
single-part object needs to be decrypted since
S3 clients expect that this ETag is equal to the
content MD5.
The `ETag.Format` method also covers SSE ETag handling.
MinIO encrypts all ETags of SSE single part objects.
However, only the ETag of SSE-S3 encrypted single part
objects needs to be decrypted.
The ETag of an SSE-C or SSE-KMS single part object
does not correspond to its content MD5 and can be
a random value.
The `ETag.Format` function formats an ETag such that
it is an AWS S3 compliant ETag. In particular, it
returns non-encrypted ETags (single / multipart)
unmodified. However, for encrypted ETags it returns
the trailing 16 bytes as ETag. For encrypted ETags
the last 16 bytes will be a random value.
The main purpose of `Format` is to format ETags
such that clients accept them as well-formed AWS S3
ETags.
It differs from the `String` method since `String`
will return string representations for encrypted
ETags that are not AWS S3 compliant.

The deployment id was being written to the health report towards the end
of the handler. Because of this, if there was a timeout in any of the

This commit simplifies the ETag decryption and size adjustment
when listing object parts.
When listing object parts, MinIO has to decrypt the ETag of all
parts if and only if the object resp. the parts is encrypted using
SSE-S3.
In case of SSE-KMS and SSE-C, MinIO returns a pseudo-random ETag.
This is inline with AWS S3 behavior.
Further, MinIO has to adjust the size of all encrypted parts due to
the encryption overhead.
The ListObjectParts does specifically not use the KMS bulk decryption
API (4d2fc530d0) since the ETags of all
parts are encrypted using the same object encryption key. Therefore,
MinIO only has to connect to the KMS once, even if there are multiple
parts resp. ETags. It can simply reuse the same object encryption key.

This commit adds support for encrypted KES
client private keys.
Now, it is possible to encrypt the KES client
private key (`MINIO_KMS_KES_KEY_FILE`) with
a password.
For example, KES CLI already supports the
creation of encrypted private keys:
```
kes identity new --encrypt --key client.key --cert client.crt MinIO
```
To decrypt an encrypted private key, the password
needs to be provided:
```
MINIO_KMS_KES_KEY_PASSWORD=<password>

This commit optimises the ETag decryption when
listing objects.
When MinIO lists objects, it has to decrypt the
ETags of single-part SSE-S3 objects.
It does not need to decrypt ETags of
- plaintext objects => Their ETag is not encrypted
- SSE-C objects => Their ETag is not the content MD5
- SSE-KMS objects => Their ETag is not the content MD5
- multipart objects => Their ETag is not encrypted
Hence, MinIO only needs to make a call to the KMS
when it needs to decrypt a single-part SSE-S3 object.
It can resolve the ETags off all other object types
locally.
This commit implements the above semantics by
processing an object listing in batches.
If the batch contains no single-part SSE-S3 object,
then no KMS calls will be made.
If the batch contains at least one single-part
SSE-S3 object we have to make at least one KMS call.
No we first filter all single-part SSE-S3 objects
such that we only request the decryption keys for
these objects.
Once we know which objects resp. ETags require a
decryption key, MinIO either uses the KES bulk
decryption API (if supported) or decrypts each
ETag serially.
This commit is a significant improvement compared
to the previous listing code. Before, a single
non-SSE-S3 object caused MinIO to fall-back to
a serial ETag decryption.
For example, if a batch consisted of 249 SSE-S3
objects and one single SSE-KMS object, MinIO would
send 249 requests to the KMS.
Now, MinIO will send a single request for exactly
those 249 objects and skip the one SSE-KMS object
since it can handle its ETag locally.
Further, MinIO would request decryption keys
for SSE-S3 multipart objects in the past - even
though multipart ETags are not encrypted.
So, if a bucket contained only multipart SSE-S3
objects, MinIO would make totally unnecessary
requests to the KMS.
Now, MinIO simply skips these multipart objects
since it can handle the ETags locally.

In bulk ETag decryption, do not rely on the etag to check if it is
encrypted or not to decide if we should set the actual object size in
ObjectInfo. The reason is that multipart objects ETags are not
encrypted.
Always get the actual object size in that case.
This commit fixes a subtle bug in the ETag
`IsEncrypted` implementation.
An encrypted ETag may contain random bytes,
i.e. some randomness used for encryption.
This random value can contain a '-' byte
simple due to being randomly generated.
Before, the `IsEncrypted` implementation
incorrectly assumed that an encrypted ETag
cannot contain a '-' since it would be a
multipart ETag. Multipart ETags have a
16 byte value followed by a '-' and the part number.
For example:
```
059ba80b807c3c776fb3bcf3f33e11ae-2
```
However, the following encrypted ETag
```
20000f00db2d90a7b40782d4cff2b41a7799fc1e7ead25972db65150118dfbe2ba76a3c002da28f85c840cd2001a28a9
```
also contains a '-' byte but is not a multipart ETag.
This commit fixes the `IsEncrypted` implementation
simply by checking whether the ETag is at least 32
bytes long. A valid multipart ETag is never 32 bytes
long since a part number must be <= 10000.
However, an encrypted ETag must be at least 32 bytes
long. It contains the encrypted ETag bytes (16 bytes)
and the authentication tag added by the AEAD cipher (again
16 bytes).

This commit adds support for bulk ETag
decryption for SSE-S3 encrypted objects.
If KES supports a bulk decryption API, then
MinIO will check whether its policy grants
access to this API. If so, MinIO will use
a bulk API call instead of sending encrypted
ETags serially to KES.
Note that MinIO will not use the KES bulk API
if its client certificate is an admin identity.
MinIO will process object listings in batches.
A batch has a configurable size that can be set
via `MINIO_KMS_KES_BULK_API_BATCH_SIZE=N`.
It defaults to `500`.

ListObjects, ListObjectsV2 calls are being heavily taxed when
there are many versions on objects left over from a previous

This commit fixes two bugs in the `PutObjectPartHandler`.
First, `PutObjectPart` should return SSE-KMS headers
when the object is encrypted using SSE-KMS.
Before, this was not the case.
Second, the ETag should always be a 16 byte hex string,
perhaps followed by a `-X` (where `X` is the number of parts).
However, `PutObjectPart` used to return the encrypted ETag
in case of SSE-KMS. This leaks MinIO internal etag details
through the S3 API.
The combination of both bugs causes clients that use SSE-KMS
to fail when trying to validate the ETag. Since `PutObjectPart`
did not send the SSE-KMS response headers, the response looked
like a plaintext `PutObjectPart` response. Hence, the client
tries to verify that the ETag is the content-md5 of the part.
This could never be the case, since MinIO used to return the
encrypted ETag.
Therefore, clients behaving as specified by the S3 protocol
tried to verify the ETag in a situation they should not.

Fix `panic: "POST /minio/peer/v21/signalservice?signal=2": sync: WaitGroup is reused before previous Wait has returned`
Log entries already on the channel would cause `logEntry` to increment the
waitgroup when sending messages, after Cancel has been called.
Instead of tracking every single message, just check the send goroutine. Faster
and safe, since it will not decrement until the channel is closed.

tmp = buf[want:]
```
Would potentially crash when `buf` is truncated for some reason
and does not have the expected bytes, this is of course considered
not normal and is an odd situation. But we do not need to crash
here instead allow for errors to be returned and let callers handle
the errors.
This PR simply adds a warning message when it detects older kernel
versions and warn's them about potential performance issues on this
kernel.
The issue can be seen only with parallel I/O across all drives
on denser setups such as 90 drives or 45 drives per server configurations.
This type of code is not necessary, read's of all
metadata content at `.minio.sys/config` automatically
triggers healing when necessary in the GetObjectNInfo()
call-path.
Having this code is not useful and this also adds to
the overall startup time of MinIO when there are lots
of users and policies.
The main goal of this PR is to solve the situation where disks stop
responding to operations. This generally causes an FD build-up and
eventually will crash the server.
This adds detection of hung disks, where calls on disk get stuck.
We add functionality to `xlStorageDiskIDCheck` where it keeps
track of the number of concurrent requests on a given disk.
A total number of 100 operations are allowed. If this limit is reached
we will block (but not reject) new requests, but we will monitor the
state of the disk.
If no requests have been completed or updated within a 15-second
window, we mark the disk as offline. Requests that are blocked will be
unblocked and return an error as "faulty disk".
New requests will be rejected until the disk is marked OK again.
Once a disk has been marked faulty, a check will run every 5 seconds that
will attempt to write and read back a file. As long as this fails the disk will
remain faulty.
To prevent lots of long-running requests to mark the disk faulty we
implement a callback feature that allows updating the status as parts
of these operations are running.
We add a reader and writer wrapper that will update the status of each
successful read/write operation. This should allow fine enough granularity
that a slow, but still operational disk will not reach 15 seconds where
50 operations have not progressed.
Note that errors themselves are not enough to mark a disk faulty.
A nil (or io.EOF) error will mark a disk as "good".
* Make concurrent disk setting configurable via `_MINIO_DISK_MAX_CONCURRENT`.
* de-couple IsOnline() from disk health tracker
The purpose of IsOnline() is to ensure that we
reconnect the drive only when the "drive" was
- disconnected from network we need to validate
if the drive is "correct" and is the same drive
which belongs to this server.
- drive was replaced we have to format it - we
support hot swapping of the drives.
IsOnline() is not meant for taking the drive offline
when it is hung, it is not useful we can let the
drive be online instead "return" errors for relevant
calls.

Possible future Improvements:
* Unify the REST server and local xlStorageDiskIDCheck. This would also improve stats significantly.
* Allow reads/writes to be aborted by the context.
* Add usage stats, concurrent count, blocked operations, etc.
Even if we specify the target namespace by `helm install --namespace`,
the StatefulSet is created on the default namespace. Since this resource
references the ServiceAccount created on the target namespace, pods are
hindered to be created. To avoid this, we deploy the StatefulSet to the
target namespace of helm.
This commit replaces the KMS / KES environment
variables with `MINIO_KMS_SECRET_KEY` when testing
healing on CI.
This change is necessary since KES `0.18.0` introduced
some API breaking changes and the healing tests run
a test (`verify-3604`) that requires an older MinIO
version (e.g. `2021-11-24T23-19-33Z`) which is not
able to parse a KES error as expected.
This commit allows the KES instance at `https://play.min.io:7373`
to get updated to newer versions.

Data usage does not always contain tiering info even if the data usage
information is valid. Avoid a crash in that case.
(e.g. the scanner scanned the namespace, the user enables tiering,
prometheus scrapes the server before the scanner gets a chance to
update the data usage with new tiering information)
Healing decisions would align with skipped folder counters. This can lead to files
never being selected for heal checks on "clean" paths.
Use different hashing methods and take objectHealProbDiv into account when

This is a side-affect of the optimization done in PR #13544 which
causes a certain type of delete operations on given object versions
can cause lastVersion indication to be skipped, which leads to
an `xl.meta` where Versions[] slice is empty while the entire
file is intact by itself.
This PR tries to ensure that such files are visible and deletable
by regular means of listing as null 'delete-marker' and also
avoid the situation where this potential issue might arise.
When scanning using normal mode, HealObject() can report an
error saying that it found a corrupted part. This doesn't have
when HealObject() is called with bitrot scan flag. However, when
this happens, we can still restart HealObject() with the bitrot scan.
This is also important because this means the scanner and the
new disks healer will not be able to heal an object that doesn't
exist in a specific disk and has corruption in another disk.
Also without this PR, mc admin heal command without bitrot will report
an error.
This commit removes some duplicate code that
converts KES API errors.
This code was added since KES `0.18.0` changed
some exported API errors. However, the KES SDK
handles this error conversion itself.
Therefore, it is not necessary to duplicate this
behavior in MinIO.

In the testing mode, reformatting disks will fail because the healing
code will complain if one disk is in root mode. This commit will
automatically set all disks as non-root if MINIO_CI_CD is set.
Currently, when applying any dynamic config, the system reloads and
re-applies the config of all the dynamic sub-systems.
This PR refactors the code in such a way that changing config of a given
dynamic sub-system will work on only that sub-system.
An onlineDisk means its a valid disk but it may be a
re-connected disk, this PR verifies that based on LastConn()
to only trigger MRF. Current code would again re-load the
disk 'format.json' which is not necessary and perhaps an
unnecessary call.
A potential side affect of this is closing perfectly online
disks and getting re-replaced by reloading 'format.json'.
This PR tries to avoid this situation by making sure MRF
is triggered but not reloading 'format.json' because of MRF.
The `LookupConfig` code was not using `GetWithDefault`, because of which
some of the config values were being returned as empty string, and calls

If the policy fails MinIO's minimum threshold for a valid policy,
they'll still (correctly) fail, but policies with a : (and probably a
/) should be allowed since they work with standard MC/MinIO

Only the first `listAndHeal` would ever be able to write on errCh, blocking all others infinitely.
Instead read all errors but return the first non-nil, if any.
The intention appears to be that this should cancel on any error,
so that part is kept.

Deleting bulk objects had an issue since the relevant versionID

Some users running MinIO claim that their system became slow. One
way to investigate is to look at this Prometheus history of the number of
the requests reaching the server. The existing current S3 requests metric
is not enough because it can increase of the system really becomes slow,
due to disk issues for example.

would spend up to 2-3secs when there are 3000+ drives

DeleteMarkers do not have a default quorum, i.e it is possible that
DeleteMarkers were created with n/2+1 quorum as well to make sure
that we satisfy situations such as those we need to make sure delete
markers only expect n/2 read quorum.
Additionally we should also look at additional metadata on the
actual objects that might have been "erasure" upgraded with new
parity when disks are down.
In such a scenario do not default to the standard storage class
parity, instead use the parityBlocks present on the FileInfo to
ensure that we are dealing with the correct quorum for READs and
DELETEs.
Retry listings, when no next marker is returned and the result isn't truncated.

The healing code repeatedly tries to heal a root disk when it is empty
the reason is that connectEndpoint() returns errUnformattedDisk even

some upgraded objects might not get listed due

This change allows the MinIO server to lookup users in different directory

This PR removes an unnecessary state that gets
passed around for DiskIDs, which is not necessary
since each disk exactly knows which pool and which
set it belongs to on a running system.
Currently cached DiskId's won't work properly
because it always ends up skipping offline disks
and never runs healing when disks are offline, as
it expects all the cached diskIDs to be present
always. This also sort of made things in-flexible
in terms perhaps a new diskID for `format.json`.
(however this is not a big issue)
This is an unnecessary requirement that healing
via scanner needs all drives to be online, instead
healing should trigger even when partial nodes
and drives are available this ensures that we
keep the SLA in-tact on the objects when disks
are offline for a prolonged period of time.
Wrong resource is being fetched, since idx is incremented, but mapID is reused.

- create internal erasure volumes only if the disk is unformatted
- return a copy of format data in xlStorage.ReadAll
- parse env vars only once, to be re-used by xl-storage
This speed-up is intended for faster startup times
for almost all MinIO operations. Changes here are
- Drives are not re-read for 'format.json' on a regular
basis once read during init is remembered and refreshed
at 5 second intervals.
- Do not do O_DIRECT tests on drives with existing 'format.json'
only fresh setups need this check.
- Parallelize initializing erasureSets for multiple sets.
- Avoid re-reading format.json when migrating 'format.json'
from really old V1->V2->V3
- Keep a copy of local drives for any given server in memory
for a quick lookup.
this helps in caching the resolved values early on, avoids
causing further resolution for individual nodes when
object layer comes online.
this can speed up our startup time during, upgrades etc by
an order of magnitude.
additional changes in connectLoadInitFormats() and parallelize
all calls that might be potentially blocking.
- Site replication was missing replicating users,

When calculating signatures empty part ETags were not discarded, leading
to a different signature compared to freshly created ones.
This would mean that after a heal signature of the healed metadata would be
different. Fixing the calculation of signature will make these consistent.
Furthermore when inconsistent entries, with zero version ID, with the same
mod times but different signatures, the one with the lowest signature would
be picked for quorum check. Since this is 50/50, we fall back to a simple
quorum count on all signatures.
Each of these fixes by themselves will lead to quorum. Tests were added
for regressions and expected outcomes.
When the replication rule is based on tag matches, the replication process
should pick up targets matching the tags specified in the replication
rule.
Fixing regression due to #12880
repeated reads on single large objects in HPC like

NVMe servers benefit always from keeping O_DIRECT on.
map labels might have been referenced else, this
can lead to concurrent access at lower layers.
avoid this by copying the information while
concurrently serving the metrics.
The code was not properly deciding if a lock needs to be removed
when it doesn't have quorum anymore. After this commit, a lock will be
forcefully unlocked if nodes reporting they are not able to find a lock
internally breaks the quorum.
Simplify the code as well.
do not allow mutation to pool command line when there are
unfinished decommissions in place, disallow such scenarios
to avoid user mistakes.
also add testcases to cover all relevant scenarios.
When reading input for PutObject or PutObjectPart add a readahead buffer for big inputs.
This will make network reads+hashing separate run async with erasure coding and writes. This will reduce overall latency in distributed setups where the input is from upstream and writes go to other servers.
We will read at 2 buffers ahead, meaning one will always be ready/waiting and one is currently being read from.
This improves PutObject and PutObjectParts for these cases.
When deleting multiple versions it "gives" up with an errFileVersionNotFound if
a version cannot be found. This effectively skips deleting other versions
sent in the same request.
This can happen on inconsistent objects. We should ignore errFileVersionNotFound
and continue with others.
We already ignore these at the caller level, this PR is continuation of 54a9877
This PR simplifies few things
- Multipart parts are renamed, upon failure are unrenamed() keep this
multipart specific behavior it is needed and works fine.
- AbortMultipart should blindly delete once lock is acquired instead
of re-reading metadata and calculating quorum, abort is a delete()
operation and client has no business looking for errors on this.
- Skip Access() calls to folders that are operating on
`.minio.sys/multipart` folder as well.
Large clusters with multiple sets, or multi-pool setups at times might
fail and report unexpected "file not found" errors. This can become
a problem during startup sequence when some files need to be created
at multiple locations.
- This PR ensures that we nil the erasure writers such that they
are skipped in RenameData() call.
- RenameData() doesn't need to "Access()" calls for `.minio.sys`
folders they always exist.
- Make sure PutObject() never returns ObjectNotFound{} for any
errors, make sure it always returns "WriteQuorum" when renameData()
fails with ObjectNotFound{}. Return appropriate errors for all
other cases.
Currently tag removal leaves replication state as `PENDING`
because the `HEAD` api returns just a tag count but not the
actual tags, and this is treated as a no-op

In a multi-pool setup when disks are coming up, or in a single pool
setup let's say with 100's of erasure sets with a slow network.
It's possible when healing is attempted on `.minio.sys/config`
folder, it can lead to healing unexpectedly deleting some policy
files as dangling due to a mistake in understanding when `isObjectDangling`
is considered to be 'true'.
This issue happened in commit 30135eed86
when we assumed the validMeta with empty ErasureInfo is considered
to be fully dangling. This implementation issue gets exposed when
the server is starting up.
This is most easily seen with multiple-pool setups because of the
disconnected fashion pools that come up. The decision to purge the
object as dangling is taken incorrectly prior to the correct state
being achieved on each pool, when the corresponding drive let's say
returns 'errDiskNotFound', a 'delete' is triggered. At this point,
the 'drive' comes online because this is part of the startup sequence
as drives can come online lazily.
This kind of situation exists because we allow (totalDisks/2) number
of drives to be online when the server is being restarted.
Implementation made an incorrect assumption here leading to policies
getting deleted.
Added tests to capture the implementation requirements.

- This allows site-replication to be configured when using OpenID or the

- When using OpenID as the external identity provider, STS and service accounts
are replicated.
- Currently this change dis-allows root service accounts from being
replicated (TODO: discuss security implications).
- This speeds up running the linters during local development. With a fully
cached run, linter completes in 8 seconds.
- Any caching issues if present would be local and would not impact CI anyway
which always starts with a clean state.
It is possible that GetLock() call remembers a previously
failed releaseAll() when there are networking issues, now
this state can have potential side effects.
This PR tries to avoid this side affect by making sure
to initialize NewNSLock() for each GetLock() attempts
made to avoid any prior state in the memory that can
interfere with the new lock grants.
The current usage of assuming `default` parity of `4` is not correct
for all objects stored on MinIO, objects in .minio.sys have maximum
parity, healing won't trigger on these objects due to incorrect
verification of quorum.
time.Format() is not necessary prematurely for JSON
marshalling, since JSON marshalling indeed defaults
to RFC3339Nano.
This also ensures the 'time' is remembered until its
logged and it is the same time when the 'caller'
invoked 'log' functions.
The AddUser() API endpoint was accepting a policy field.
This API is used to update a user's secret key and account

user value exists for the credential, which corresponds to the user for whom the
credentials are created. The access policy is mapped to this parent-user and is
persisted. This helps ensure that all STS credentials of a user have the same
policy assignment at all times.
Before this change, for an OIDC STS credential, when the policy claim changes in
the provider (when not using RoleARNs), the change would not take effect on
existing credentials, but only on new ones.
To support existing STS credentials without parent-user policy mappings, we
lookup the policy in the policy claim value. This behavior should be deprecated
when such support is no longer required, as it can still lead to stale
policy mappings.
Additionally this change also simplifies the implementation for all non-RoleARN
STS credentials. Specifically, for AssumeRole (internal IDP) STS credentials,
policies are picked up from the parent user's policies; for
AssumeRoleWithCertificate STS credentials, policies are picked up from the
parent user mapping created when the STS credential is generated.
AssumeRoleWithLDAP already picks up policies mapped to the virtual parent user.
A corner case can occur where the delete-marker was propagated
but the metadata could not be updated on the primary. Sending
a RemoveObject call with the Delete marker version would end
up permanently deleting the version on target. Instead, perform
a Stat on the delete-marker version on target and redo replication
only if the delete-marker is missing on target.
After the introduction of Refresh logic in locks, the data scanner can
quit when the data scanner lock is not able to get refreshed. In that
case, the context of the data scanner will get canceled and
runDataScanner() will quit. Another server would pick the scanning
routine but after some time, all nodes can just have all scanning
routine aborted, as described above.
This fix will just run the data scanner in a loop.
Return as soon as an AND fails and whenever an OR succeeds. Faster and more flexible.
For example makes `select * from S3object where _2 != '' AND _2 > 1` able to operate on empty fields.
Followup to #13900
minisign v0.10.0 tool broke compatibility, that leads
to our library failing to parse the newer signatures.
This PR
fixes - https://github.com/minio/operator/issues/913

A workaround for users facing this problem is to unset

```
or set it to `empty` string then signature verification
is skipped automatically.
These changes have been migrated from the previous chart: https://github.com/helm/charts/tree/master/stable/minio
Added `GCS` support for gateway mode in the helm chart.
Added a new GCS block under the gateway key to the house
the GCS-specific variables.
The gateway-deployment template now sets the env var: GOOGLE_APPLICATION_CREDENTIALS as a path to the

- Allow proper SRError to be propagated to
handlers and converted appropriately.
- Make sure to enable object locking on buckets
when requested in MakeBucketHook.
- When DNSConfig is enabled attempt to delete it
first before deleting buckets locally.
- Rename MaxNoncurrentVersions tag to NewerNoncurrentVersions
Note: We apply overlapping NewerNoncurrentVersions rules such that
we honor the highest among applicable limits. e.g if 2 overlapping rules
are configured with 2 and 3 noncurrent versions to be retained, we
will retain 3.
- Expire newer noncurrent versions after noncurrent days
- MinIO extension: allow noncurrent days to be zero, allowing expiry
of noncurrent version as soon as more than configured
NewerNoncurrentVersions are present.
- Allow NewerNoncurrentVersions rules on object-locked buckets
- No x-amz-expiration when NewerNoncurrentVersions configured
- ComputeAction should skip rules with NewerNoncurrentVersions > 0
- Add unit tests for lifecycle.ComputeAction
- Support lifecycle rules with MaxNoncurrentVersions
- Extend ExpectedExpiryTime to work with zero days
- Fix all-time comparisons to be relative to UTC
- This introduces a new admin API with a query parameter (v=2) to return a
response with the timestamps
- Older API still works for compatibility/smooth transition in console
- allow any regular user to change their own password
- allow STS credentials to create users if permissions allow
Bonus: do not allow changes to sts/service account credentials (via add user API)
ListObjects() should never list a delete-marked folder

an S3 API behaves for ListObjects() without

- deleting policies was deleting all LDAP
user mapping, this was a regression introduced
in #13567
- deleting of policies is properly sent across

- remove unexpected errors instead embed the real

- deleteBucket() should be called for cleanup
if client abruptly disconnects
- out of disk errors should be sent to client
properly and also cancel the calls
- limit concurrency to available MAXPROCS not
32 for auto-tuned setup, if procs are beyond
32 then continue normally. this is to handle
smaller setups.

Return errors when untar fails at once.
Current error handling was quite a mess. Errors are written
to the stream, but processing continues.
Instead, return errors when they occur and transform
internal errors to bad request errors, since it is likely a
problem with the input.
Fixes#13832
Sometimes, we see an error message like "Server expects 'storage' API
version 'v41', instead found 'v41'" shows a more generic error message
with the path of the REST call.
The earlier approach of using a license token for
communicating with SUBNET is being replaced
with a simpler mechanism of API keys. Unlike the
license which is a JWT token, these API keys will
be simple UUID tokens and don't have any embedded
information in them. SUBNET would generate the
API key on cluster registration, and then it would
be saved in this config, to be used for subsequent
communication with SUBNET.
Following scenario such as objects that exist inside a
prefix say `folder/` must be included in the listObjects()
response.
```
2aa16073-387e-492c-9d59-b4b0b7b6997a v2 DEL folder/
a5b9ce68-7239-4921-90ab-20aed402c7a2 v1 PUT folder/
f2211798-0eeb-4d9e-9184-fcfeae27d069 v1 PUT folder/1.txt
```
Current master does not handle this scenario, because it
ignores the top level delete-marker on folders. This is
however unexpected. It is expected that list-objects returns
the top level prefix in this situation.
```
aws s3api list-objects --bucket harshavardhana --prefix unique/ \
--delimiter / --profile minio --endpoint-url http://localhost:9000
{
"CommonPrefixes": [
{
"Prefix": "unique/folder/"
}
]
}
```
There are applications in the wild such as Hadoop s3a connector
that exploit this behavior and expect the folder to be present
in the response.
This also makes the behavior consistent with AWS S3.

- Allows setting a role policy parameter when configuring OIDC provider
- When role policy is set, the server prints a role ARN usable in STS API requests
- The given role policy is applied to STS API requests when the roleARN parameter is provided.
- Service accounts for role policy are also possible and work as expected.
- New sub-system has "region" and "name" fields.
- `region` subsystem is marked as deprecated, however still works, unless the
new region parameter under `site` is set - in this case, the region subsystem is
ignored. `region` subsystem is hidden from top-level help (i.e. from `mc admin
config set myminio`), but appears when specifically requested (i.e. with `mc
admin config set myminio region`).
- MINIO_REGION, MINIO_REGION_NAME are supported as legacy environment variables for server region.
- Adds MINIO_SITE_REGION as the current environment variable to configure the
server region and MINIO_SITE_NAME for the site name.
The index was converted directly from bytes to binary. This would fail a roundtrip through json.

FileInfo quorum shouldn't be passed down, instead

This PR also changes other functions that rely on
wrong quorum calculation.
Update tests as well to handle the proper requirement. All
these changes are needed when migrating from older deployments
where we used to set N/2 quorum for reads to EC:4 parity in
newer releases.
dataDir loosely based on maxima is incorrect and does not
work in all situations such as disks in the following order
- xl.json migration to xl.meta there may be partial xl.json's
leftover if some disks are not yet connected when the disk
is yet to come up, since xl.json mtime and xl.meta is
same the dataDir maxima doesn't work properly leading to
quorum issues.
- its also possible that XLV1 might be true among the disks
available, make sure to keep FileInfo based on common quorum
and skip unexpected disks with the older data format.
Also, this PR tests upgrade from older to a newer release if the
data is readable and matches the checksum.
NOTE: this is just initial work we can build on top of this to do further tests.
there is a corner case where the new check
doesn't work where dataDir has changed, especially
when xl.json -> xl.meta healing happens, if some
healing is partial this can make certain backend
files unreadable.
This PR fixes and updates unit-tests
This unit allows users to limit the maximum number of noncurrent
versions of an object.
To enable this rule you need the following *ilm.json*
```
cat >> ilm.json <<EOF

"Status": "Enabled",
"Filter": {
"Prefix": "user-uploads/"
},

}
}
]
}
EOF
mc ilm import myminio/mybucket < ilm.json
```
currently getReplicationConfig() failure incorrectly
returns error on unexpected buckets upon upgrade, we
should always calculate usage as much as possible.
listing can fail and it is allowed to be retried,
instead of returning right away return an error at
the end - heal the rest of the buckets and objects,
and when we are retrying skip the buckets that
are already marked done by using the tracked buckets.

}
```
xlMetaV2VersionHeader is <= 30 bytes serialized. Deserialized struct
can easily be reused and does not contain pointers, so efficient as a
slice (single allocation)
This allows quickly parsing everything as slices of bytes (no copy).
Versions are always *saved* sorted by modTime, newest *first*.
No more need to sort on load.
* Allows checking if a version exists.
* Allows reading single version without unmarshal all.
* Allows reading latest version of type without unmarshal all.
* Allows reading latest version without unmarshal of all.
* Allows checking if the latest is deleteMarker by reading first entry.
* Allows adding/updating/deleting a version with only header deserialization.
* Reduces allocations on conversion to FileInfo(s).
This will help other projects like `health-analyzer` to verify that the
struct was indeed populated by the minio server, and is not
default-populated during unmarshalling of the JSON.

legacy objects in 'xl.json' after upgrade, should have

enabled and the object should have been overwritten with
another version of an object.

This commit makes the MinIO server behavior more consistent
w.r.t. key usage verification.
When MinIO verifies the client certificates it also checks
that the client certificate is valid of client authentication
(or any (i.e. wildcard) usage).
However, the MinIO server used to not verify the client key usage
when client certificate verification was disabled.
Now, the MinIO server verifies the client key usage even when
client certificate verification has been disabled. This makes
the MinIO behavior more consistent from a client's perspective.
Now, a client certificate has to be valid for client authentication
in all cases.

Looks like policy restriction was not working properly
for normal users when they are not svc or STS accounts.
- svc accounts are now properly fixed to get
right permissions when its inherited, so
we do not have to set 'owner = true'
- sts accounts have always been using right
permissions, do not need an explicit lookup
- regular users always have proper policy mapping
- avoids relying in listQuorum from the underlying listObjects()
and potentially missing entries if any.
- avoid the entire merging logic etc, listing raw set by set
and loading whatever is found is cleaner when dealing with
a large cluster for IAM metadata.

This was a regression introduced in '14bb969782'
this has the potential to cause corruption when
there are concurrent overwrites attempting to update
the content on the namespace.
This PR adds a situation where PutObject(), CopyObject()
compete properly for the same locks with NewMultipartUpload()
however it ends up turning off competing locks for the actual
object with GetObject() and DeleteObject() - since they do not
compete due to concurrent I/O on a versioned bucket it can lead
to loss of versions.
This PR fixes this bug with multi-pool setup with replication
that causes corruption of inlined data due to lack of competing
locks in a multi-pool setup.
Instead CompleteMultipartUpload holds the necessary
locks when finishing the transaction, knowing the exact
location of an object to schedule the multipart upload
doesn't need to compete in this manner, a pool id location
for existing object.
This reverts commit 91567ba916.
Revert because the error was incorrectly converted, there are
callers that rely on errConfigNotFound and it also took away
the migration code.
Instead the correct fix is PutBucketTaggingHandler() which
is already added.
also remove HealObjects() code from dataScanner running another
listing from the data-scanner is super in-efficient and in-fact
this code is redundant since we already attempt to heal all
dangling objects anyways.
- Supports object locked buckets that require
PutObject() to set content-md5 always.
- Use SSE-S3 when S3 gateway is being used instead

- globalNotificationSys
- globalTargetSys

DeleteObject() on existing objects before `xl.json` to
`xl.meta` change were not working, not sure when this
regression was added. This PR fixes this properly.
Also this PR ensures that we perform rename of xl.json
to xl.meta only during "write" phase of the call i.e
either during Healing or PutObject() overwrites.
Also handles few other scenarios during migration where
`backendEncryptedFile` was missing deleteConfig() will
fail with `configNotFound` this case was not ignored,
which can lead to failure during upgrades.
once we have competed for locks, verify if the
context is still valid - this is to ensure that
we do not start readdir() or read() calls on the
drives on canceled connections.
This commit brings two locks instead of single lock for
WalkDir() calls on top of c25816eabc.
The main reason is to avoid contention between readMetadata()
and ListDir() calls, ListDir() can take time on prefixes that
are huge for readdir() but this shouldn't end up blocking
all readMetadata() operations, this allows for more room for
I/O while not overly penalizing all listing operations.
This commit fixes an issue in the `AssumeRoleWithCertificate`
handler.
Before clients received an error when they send
a chain of X.509 certificates (their client certificate as
well as intermediate / root CAs).
Now, client can send a certificate chain and the server
will only consider non-CA / leaf certificates as possible
client certificate candidates. However, the client still
can only send one certificate.

Some identity providers like GitLab do not provide
information about group membership as part of the
identity token claims. They only expose it via OIDC compatible
'/oauth/userinfo' endpoint, as described in the OpenID
Connect 1.0 sepcification.
But this of course requires application to make sure to add
additional accessToken, since idToken cannot be re-used to
perform the same 'userinfo' call. This is why this is specialized
requirement. Gitlab seems to be the only OpenID vendor that requires
this support for the time being.

Don't perform an independent evaluation of inlining, but mirror the decision made when uploading the object.

Replication was not working properly for encrypted
objects in single PUT object for preserving etag,
We need to make sure to preserve etag such that replication
works properly and not gets into infinite loops of copying

This will allow objects to relinquish read lock held during
replication earlier if the target is known to be down

This commit adds a new STS API for X.509 certificate
authentication.
A client can make an HTTP POST request over a TLS connection
and MinIO will verify the provided client certificate, map it to an
S3 policy and return temp. S3 credentials to the client.
So, this STS API allows clients to authenticate with X.509
certificates over TLS and obtain temp. S3 credentials.

#11878 added "keepHTTPResponseAlive" to CreateFile requests.
The problem is that it will begin writing to the response before the
body is read after 10 seconds. This will abort the writes on the
client-side, since it assumes the server has received what it wants.
The proposed solution here is to monitor the completion of the body
before beginning to send keepalive pings.
Fixes observed high number of goroutines stuck in `io.Copy` in
`github.com/minio/minio/cmd.(*xlStorage).CreateFile` and
`(*storageRESTClient).CreateFile` stuck in `http.DrainBody`.
In the event when a lock is not refreshed in the cluster, this latter
will be automatically removed in the subsequent cleanup of non
refreshed locks routine, but it forgot to clean the local server,
hence having the same weird stale locks present.
This commit will remove the lock locally also in remote nodes, if
removing a lock from a remote node will fail, it will be anyway
removed later in the locks cleanup routine.
Currently in master this can cause existing

We are observing heavy system loads, potentially
locking the system up for periods when concurrent

We place a per-disk lock on walk IO operations.
This will minimize the impact of concurrent listing

Single list operations should remain largely unaffected.
Some applications albeit poorly written rather than using headObject

- multiple-pools optimization deletes don't need to hold
read locks verifying objects across namespace and pools.
baseDir is empty if the top level prefix does not

this healing optimization caused multiple
regressions in healing
- delete-markers incorrectly missing
heal and returning incorrect healing
results to client.
- missing individual 'parts' such
as for restored object or simply
for all objects just missing few parts.
This optimization is not necessary, we
should proceed to verify all cases possible
not just when metadata is inconsistent.
destination path and old path will be similar
when healing occurs, this can lead to healed
parts being again purged leading to always an
inconsistent state on an object which might
further cause reduction in quorum eventually.
delete-markers missing on drives were
not healed due to few things

fixes#12787
- delete-markers are incorrectly reported
as corrupt with wrong data sent to client
'mc admin heal -r' on objects with delete
marker will report as 'grey' incorrectly.
- do not heal delete-markers during HeadObject()
this can lead to inconsistent order of heals
on the object, although this is not an issue
in terms of order of versions it is rather
simpler to keep the same order on all drives.
- defaultHealResult() should handle 'err == nil'
case such that valid cases should be handled
as 'drive' status OK.
- remove use of getOnlineDisks() instead rely on fallbackDisks()
when disk return errors like diskNotFound, unformattedDisk
use other fallback disks to list from, instead of paying the
price for checking getOnlineDisks()
- optimize getDiskID() further to avoid large write locks when
looking formatLastCheck time window
This new change allows for a more relaxed fallback for listing
allowing for more tolerance and also eventually gain more
consistency in results even if using '3' disks by default.

Also additionally allow users to specify

the console UI etc.
This needs to be done additionally for any
MinIO deployments that might have a much more

This allows remote bucket admin to identify the origin of transitioned
objects by simply inspecting the object prefixes.
e.g let's take a remote tier TIER-1 pointing to a remote bucket (prefix)
testbucket/testprefix-1. The remote bucket admin can list all transitioned objects
from a MinIO deployment identified by '2e78e906-1c5d-4f94-8689-9df44cafde39' and
source bucket 'mybucket' like so,
```
$ ./mc ls -r minio-tier-target/testbucket/testprefix-1/2e78e906-1c5d-4f94-8689-9df44cafde39/mybucket/

Ensure that hostnames / ip addresses are not printed in the subnet
health report. Anonymize them by replacing them with `servern` where `n`

This is done by building a `host anonymizer` map that maps every
possible value containing the host e.g. host, host:port,
http://host:port, etc to the corresponding anonymized name and using
this map to replace the values at the time of health report generation.
A different logic is used to anonymize host names in the `procinfo`
data, as the host names are part of an ellipses pattern in the process
start command. Here we just replace the prefix/suffix of the ellipses
pattern with their hashes.

Each multipart upload is holding a read lock for the entire upload
duration of each part.
This makes it impossible for other parts to complete until all currently
uploading parts have released their locks.
It will also make it impossible for new parts to start as long as the
write lock is still being requested, essentially deadlocking uploads
until all that may have been granted a read lock has been completed.
Refactor to only hold the upload id lock while reading and writing
the metadata, but hold a part id lock while the part is being uploaded.

Real-time metrics calculated in-memory rely on the initial
replication metrics saved with data usage. However, this can
lag behind the actual state of the cluster at the time of server
restart leading to inaccurate Pending size/counts reported to
Prometheus. Dropping the Pending metrics as this can be more
reliably monitored by applications with replication notifications.

LDAPusername is the simpler form of LDAPUser (userDN),
using a simpler version is convenient from policy
conditions point of view, since these are unique id's
used for LDAP login.
In cases where a cluster is degraded, we do not uphold our consistency
guarantee and we will write fewer erasure codes and rely on healing
to recreate the missing shards.
In some cases replacing known bad disks in practice take days.
We want to change the behavior of a known degraded system to keep
the erasure code promise of the storage class for each object.
This will create the objects with the same confidence as a fully
functional cluster. The tradeoff will be that objects created
during a partial outage will take up slightly more space.
This means that when the storage class is EC:4, there should
always be written 4 parity shards, even if some disks are unavailable.
When an object is created on a set, the disks are immediately
checked. If any disks are unavailable additional parity shards
will be made for each offline disk, up to 50% of the number of disks.
We add an internal metadata field with the actual and intended
erasure code level, this can optionally be picked up later by
the scanner if we decide that data like this should be re-sharded.
Bonus change LDAP settings such as user, group mappings
are now listed as part of `mc admin user list` and
`mc admin group list`
Additionally this PR also deprecates the `/v2` API
that is no longer in use.
A configured audit logger or HTTP logger is validated during MinIO
server startup. Relax the timeout to 10 seconds in that case, otherwise,
both loggers won't be used.
1 second could be too low for a busy HTTP endpoint.
This commit fixes a bug causing the MinIO server to compute
the ETag of a single-part object as MD5 of the compressed
content - not as MD5 of the actual content.
This usually does not affect clients since the MinIO appended
a `-1` to indicate that the ETag belongs to a multipart object.
However, this behavior was problematic since:
- A S3 client being very strict should reject such an ETag since
the client uploaded the object via single-part API but got
a multipart ETag that is not the content MD5.
- The MinIO server leaks (via the ETag) that it compressed the
object.
This commit addresses both cases. Now, the MinIO server returns
an ETag equal to the content MD5 for single-part objects that got
compressed.

A lot of healing is likely to be on non-existing objects and
locks are very expensive and will slow down scanning

Compressed files always start at the beginning of a part so no additional offset should be added.
Previous PR #12351 added functions to read from the reader
stream to reduce memory usage, use the same technique in
few other places where we are not interested in reading the
data part.
in setups with lots of drives the server
startup is slow, initialize all local drives
in parallel before registering with muxer.
this speeds up when there are multiple pools
and large collection of drives.
multi-disk clusters initialize buffer pools
per disk, this is perhaps expensive and perhaps
not useful, for a running server instance. As this
may disallow re-use of buffers across sets,
this change ensures that buffers across sets
can be re-used at drive level, this can reduce
quite a lot of memory on large drive setups.
In lieu of new changes coming for server command line, this
change is to deprecate strict requirement for distributed setups
to provide root credentials.
Bonus: remove MINIO_WORM warning from April 2020, it is time to

However, this slice is also used for closing the writers, so close is never called on these.

Bonus: purge unused function deleteEmptyDir()

available - print enough information for administrator
to notice the errors in console.
Bonus: for really large streams use larger buffer for
writes.
- GetObject() should always use a common dataDir to
read from when it starts reading, this allows the
code in erasure decoding to have sane expectations.
- Healing should always heal on the common dataDir, this
allows the code in dangling object detection to purge
dangling content.
These both situations can happen under certain types of
retries during PUT when server is restarting etc, some
namespace entries might be left over.
attempt a delete on remote DNS store first before
attempting locally, because removing at DNS store

This commit adds support for SSE-KMS bucket configurations.
Before, the MinIO server did not support SSE-KMS, and therefore,
it was not possible to specify an SSE-KMS bucket config.
Now, this is possible. For example:
```
mc encrypt set sse-kms some-key <alias>/my-bucket
```
Further, this commit fixes an issue caused by not supporting
SSE-KMS bucket configuration and switching to SSE-KMS as default
SSE method.
Before, the server just checked whether an SSE bucket config was
present (not which type of SSE config) and applied the default
SSE method (which was switched from SSE-S3 to SSE-KMS).
This caused objects to get encrypted with SSE-KMS even though a
SSE-S3 bucket config was present.
This issue is fixed as a side-effect of this commit.

A cache structure will be kept with a tree of usages.
The cache is a tree structure where each keeps track
of its children.
An uncompacted branch contains a count of the files
only directly at the branch level, and contains link to
children branches or leaves.
The leaves are "compacted" based on a number of properties.
A compacted leaf contains the totals of all files beneath it.
A leaf is only scanned once every dataUsageUpdateDirCycles,
rarer if the bloom filter for the path is clean and no lifecycles
are applied. Skipped leaves have their totals transferred from
the previous cycle.
A clean leaf will be included once every healFolderIncludeProb
for partial heal scans. When selected there is a one in
healObjectSelectProb that any object will be chosen for heal scan.
Compaction happens when either:
- The folder (and subfolders) contains less than dataScannerCompactLeastObject objects.
- The folder itself contains more than dataScannerCompactAtFolders folders.
- The folder only contains objects and no subfolders.
- A bucket root will never be compacted.
Furthermore, if a has more than dataScannerCompactAtChildren recursive
children (uncompacted folders) the tree will be recursively scanned and the
branches with the least number of objects will be compacted until the limit
is reached.
This ensures that any branch will never contain an unreasonable amount
of other branches, and also that small branches with few objects don't
take up unreasonable amounts of space.
Whenever a branch is scanned, it is assumed that it will be un-compacted
before it hits any of the above limits. This will make the branch rebalance
itself when scanned if the distribution of objects has changed.
TLDR; With current values: No bucket will ever have more than 10000
child nodes recursively. No single folder will have more than 2500 child
nodes by itself. All subfolders are compacted if they have less than 500
objects in them recursively.
We accumulate the (non-deletemarker) version count for paths as well,
since we are changing the structure anyway.
MRF does not detect when a node is disconnected and reconnected quickly
this change will ensure that MRF is alerted by comparing the last disk
reconnection timestamp with the last MRF check time.

This change fixes handling of these types of queries:
- Double quoted column names with special characters:
SELECT "column.name" FROM s3object
- Double quoted column names with reserved keywords:
SELECT "CAST" FROM s3object
- Table name as prefix for column names:
SELECT S3Object."CAST" FROM s3object
This commit adds a self-test for all bitrot algorithms:
- SHA-256
- BLAKE2b
- HighwayHash
The self-test computes an incremental checksum of pseudo-random
messages. If a bitrot algorithm implementation stops working on
some CPU architecture or with a certain Go version this self-test
will prevent the server from starting and silently corrupting data.
For additional context see: minio/highwayhash#19
Metrics calculation was accumulating inital usage across all nodes
rather than using initial usage only once.
Also fixing:
- bug where all peer traffic was going to the same node.
- reset counters when replication status changes from
PENDING -> FAILED
This PR fixes
- close leaking bandwidth report channel leakage
- remove the closer requirement for bandwidth monitor
instead if Read() fails remember the error and return
error for all subsequent reads.
- use locking for usage-cache.bin updates, with inline
data we cannot afford to have concurrent writes to
usage-cache.bin corrupting xl.meta
implementation in #11949 only catered from single
node, but we need cluster metrics by capturing
from all peers. introduce bucket stats API that
will be used for capturing in-line bucket usage
as well eventually
Current implementation heavily relies on readAllFileInfo
but with the advent of xl.meta inlined with data, we cannot
easily avoid reading data when we are only interested is
updating metadata, this leads to invariably write
amplification during metadata updates, repeatedly reading
data when we are only interested in updating metadata.
This PR ensures that we implement a metadata only update
API at storage layer, that handles updates to metadata alone
for any given version - given the version is valid and
present.
This helps reduce the chattiness for following calls..
- PutObjectTags
- DeleteObjectTags
- PutObjectLegalHold
- PutObjectRetention
- ReplicateObject (updates metadata on replication status)
- collect real time replication metrics for prometheus.
- add pending_count, failed_count metric for total pending/failed replication operations.
- add API to get replication metrics
- add MRF worker to handle spill-over replication operations
- multiple issues found with replication
- fixes an issue when client sends a bucket
name with `/` at the end from SetRemoteTarget
API call make sure to trim the bucket name to
avoid any extra `/`.
- hold write locks in GetObjectNInfo during replication
to ensure that object version stack is not overwritten
while reading the content.
- add additional protection during WriteMetadata() to
ensure that we always write a valid FileInfo{} and avoid
ever writing empty FileInfo{} to the lowest layers.

current master breaks this important requirement
we need to preserve legacyXLv1 format, this is simply
ignored and overwritten causing a myriad of issues
by leaving stale files on the namespace etc.
for now lets still use the two-phase approach of
writing to `tmp` and then renaming the content to
the actual namespace.
versionID is the one that needs to be preserved and as
well as overwritten in case of replication, transition
etc - dataDir is an ephemeral entity that changes
during overwrites - make sure that versionID is used
to save the object content.
this would break things if you are already running
the latest master, please wipe your current content
and re-do your setup after this change.
upgrading from 2yr old releases is expected to work,
the issue was we were missing checksum info to be
passed down to newBitrotReader() for whole bitrot
calculation
Ensure that we don't use potentially broken algorithms for critical functions, whether it be a runtime problem or implementation problem for a specific platform.
It is inefficient to decide to heal an object before checking its
lifecycle for expiration or transition. This commit will just reverse
the order of action: evaluate lifecycle and heal only if asked and
lifecycle resulted a NoneAction.
replication didn't work as expected when deletion of
delete markers was requested in DeleteMultipleObjects
API, this is due to incorrect lookup elements being
used to look for delete markers.
This allows us to speed up or slow down sleeps
between multiple scanner cycles, helps in testing
as well as some deployments might want to run
scanner more frequently.
This change is also dynamic can be applied on
a running cluster, subsequent cycles pickup
the newly set value.
using Lstat() is causing tiny memory allocations,
that are usually wasted and never used, instead
we can simply uses Access() call that does 0
memory allocations.
This feature brings in support for auto extraction
of objects onto MinIO's namespace from an incoming
tar gzipped stream, the only expected metadata sent
by the client is to set `snowball-auto-extract`.
All the contents from the tar stream are saved as
folders and objects on the namespace.
fixes#8715
service accounts were not inheriting parent policies
anymore due to refactors in the PolicyDBGet() from
the latest release, fix this behavior properly.
The local node name is heavily used in tracing, create a new global
variable to store it. Multiple goroutines can access it since it won't be
changed later.
In #11888 we observe a lot of running, WalkDir calls.
There doesn't appear to be any listerners for these calls, so they should be aborted.
Ensure that WalkDir aborts when upstream cancels the request.
Fixes#11888
The background healing can return NoSuchUpload error, the reason is that
healing code can return errFileNotFound with three parameters. Simplify
the code by returning exact errUploadNotFound error in multipart code.
Also ensure that a typed error is always returned whatever the number of
parameters because it is better than showing internal error.
For large objects taking more than '3 minutes' response
times in a single PUT operation can timeout prematurely
as 'ResponseHeader' timeout hits for 3 minutes. Avoid
this by keeping the connection active during CreateFile
phase.
baseDirFromPrefix(prefix) for object names without
parent directory incorrectly uses empty path, leading
to long listing at various paths that are not useful
for healing - avoid this listing completely if "baseDir"
returns empty simple use the "prefix" as is.
this improves startup performance significantly
For large objects taking more than '3 minutes' response
times in a single PUT operation can timeout prematurely

this by keeping the connection active during CreateFile

some SDKs might incorrectly send duplicate
entries for keys such as "conditions", Go
stdlib unmarshal for JSON does not support
duplicate keys - instead skips the first
duplicate and only preserves the last entry.
This can lead to issues where a policy JSON
while being valid might not properly apply
the required conditions, allowing situations
where POST policy JSON would end up allowing
uploads to unauthorized buckets and paths.
This PR fixes this properly.
This commit adds a `MarshalText` implementation
to the `crypto.Context` type.
The `MarshalText` implementation replaces the
`WriteTo` and `AppendTo` implementation.
It is slightly slower than the `AppendTo` implementation

However, the `AppendTo` benchmark used a pre-allocated buffer. While
this improves its performance it does not match the actual usage of
`crypto.Context` which is passed to a `KMS` and always encoded into
a newly allocated buffer.
Therefore, this change seems acceptable since it should not impact the
actual performance but reduces the overall code for Context marshaling.
When an object is removed, its parent directory is inspected to check if
it is empty to remove if that is the case.
However, we can use os.Remove() directly since it is only able to remove
a file or an empty directory.
RenameData renames xl.meta and data dir and removes the parent directory
if empty, however, there is a duplicate check for empty dir, since the
parent dir of xl.meta is always the same as the data-dir.
Some old AWS SDKs send BucketLifecycleConfiguration as the root tag in
the bucket lifecycle document. This PR will support both
LifecycleConfiguration and BucketLifecycleConfiguration.
on freshReads if drive returns errInvalidArgument, we
should simply turn-off DirectIO and read normally, there
are situations in k8s like environments where the drives
behave sporadically in a single deployment and may not
have been implemented properly to handle O_DIRECT for
reads.
This PR adds deadlines per Write() calls, such
that slow drives are timed-out appropriately and
the overall responsiveness for Writes() is always
up to a predefined threshold providing applications
sustained latency even if one of the drives is slow
to respond.

MRF was starting to heal when it receives a disk connection event, which
is not good when a node having multiple disks reconnects to the cluster.
Besides, MRF needs Remove healing option to remove stale files.
- write in o_dsync instead of o_direct for smaller
objects to avoid unaligned double Write() situations
that may arise for smaller objects < 128KiB
- avoid fallocate() as its not useful since we do not
use Append() semantics anymore, fallocate is not useful
for streaming I/O we can save on a syscall
- createFile() doesn't need to validate `bucket` name
with a Lstat() call since createFile() is only used
to write at `minioTmpBucket`
- use io.Copy() when writing unAligned writes to allow
usage of ReadFrom() from *os.File providing zero
buffer writes().

This commit fixes a security issue in the signature v4 chunked
reader. Before, the reader returned unverified data to the caller
and would only verify the chunk signature once it has encountered
the end of the chunk payload.
Now, the chunk reader reads the entire chunk into an in-memory buffer,
verifies the signature and then returns data to the caller.
In general, this is a common security problem. We verifying data
streams, the verifier MUST NOT return data to the upper layers / its
callers as long as it has not verified the current data chunk / data
segment:
```
func (r *Reader) Read(buffer []byte) {
if err := r.readNext(r.internalBuffer); err != nil {
return err
}
if err := r.verify(r.internalBuffer); err != nil {
return err
}
copy(buffer, r.internalBuffer)
}
```
For operations that require the object to exist make it possible to
detect if the file isn't found in *any* pool.
This will allow these to return the error early without having to re-check.
Cases where we have applications making request
for `//` in object names make sure that all
are normalized to `/` and all such requests that
are prefixed '/' are removed. To ensure a
consistent view from all operations.
Some deployments have low parity (EC:2), but we really do not need to
save our config data with the same parity configuration.
N/2 would be better to keep MinIO configurations intact when unexpected
a number of drives fail.
This commit disables the Hashicorp Vault
support but provides a way to temp. enable
it via the `MINIO_KMS_VAULT_DEPRECATION=off`
Vault support has been deprecated long ago
and this commit just requires users to take
action if they maintain a Vault integration.
This commit adds FIPS-specifc build tags to the madmin

This change should affect all new uploads, previous uploads should
continue to work with business as usual. But dramatic improvements can
be seen with these changes.
A group can have multiple policies, a user subscribed to readwrite &

However, the current code only returns one policy for one group.
This commit disables SHA-3 for OpenID when building a
FIPS-140 2 compatible binary. While SHA-3 is a
crypto. hash function accepted by NIST there is no
FIPS-140 2 compliant implementation available when
using the boringcrypto Go branch.
Therefore, SHA-3 must not be used when building
a FIPS-140 2 binary.
* Provide information on *actively* healing, buckets healed/queued, objects healed/failed.
* Add concurrent healing of multiple sets (typically on startup).
* Add bucket level resume, so restarts will only heal non-healed buckets.
* Print summary after healing a disk is done.
currently when one of the peer is down, the
drives from that peer are reported as '0/0'
offline instead we should capture/filter the
drives from the peer and populate it appropriately
such that `mc admin info` displays correct info.
This commit adds the `FromContentMD5` function to
parse a client-provided content-md5 as ETag.
Further, it also adds multipart ETag computation
for future needs.
prometheus metrics was using total disks instead
of online disk count, when disks were down, this
PR fixes this and also adds a new metric for
total_disk_count
Creating notification events for replica creation
is not particularly useful to send as the notification
event generated at source already includes replication
completion events.
For applications using replica cluster as failover, avoiding
duplicate notifications for replica event will allow seamless
failover.
also re-use storage disks for all `mc admin server info`
calls as well, implement a new LocalStorageInfo() API
call at ObjectLayer to lookup local disks storageInfo
also fixes bugs where there were double calls to StorageInfo()
While starting up a request that needs all IAM data will start another load operation if the first on startup hasn't finished. This slows down both operations.
Block these requests until initial load has completed.
Blocking calls will be ListPolicies, ListUsers, ListServiceAccounts, ListGroups - and the calls that eventually trigger these. These will wait for the initial load to complete.
Fixes issue seen in #11305
Implicit permissions for any user is to be allowed to
change their own password, we need to restrict this
further even if there is an implicit allow for this
scenario - we have to honor Deny statements if they
are specified.
ListObjectVersions would skip past the object in the marker when version id is specified.
Make `listPath` return the object with the marker and truncate it if not needed.
Avoid having to parse unintended objects to find a version marker.
The previous code was iterating over replies from peers and assigning
pool numbers to them, thus missing to add it for the local server.
Fixed by iterating over the server properties of all the servers
including the local one.
There was an io.LimitReader was missing for the 'length'
parameter for ranged requests, that would cause client to
get truncated responses and errors.
fixes#11651
The base profiles contains no valuable data, don't record them.
Reduce block rate by 2 orders of magnitude, should still capture just as valuable data with less CPU strain.
most of the delete calls today spend time in
a blocking operation where multiple calls need
to be recursively sent to delete the objects,
instead we can use rename operation to atomically
move the objects from the namespace to `tmp/.trash`
we can schedule deletion of objects at this
location once in 15, 30mins and we can also add
wait times between each delete operation.
this allows us to make delete's faster as well
less chattier on the drives, each server runs locally
a groutine which would clean this up regularly.
This commit removes the `GetObject` method
from the `ObjectLayer` interface.
The `GetObject` method is not longer used by
the HTTP handlers implementing the high-level
S3 semantics. Instead, they use the `GetObjectNInfo`
method which returns both, an object handle as well
as the object metadata.
Therefore, it is no longer necessary that a concrete
`ObjectLayer` implements `GetObject`.
store the cache in-memory instead of disks to avoid large
write amplifications for list heavy workloads, store in
memory instead and let it auto expire.
This commit replaces the usage of
github.com/minio/sha256-simd with crypto/sha256
of the standard library in all non-performance
critical paths.
This is necessary for FIPS 140-2 compliance which
requires that all crypto. primitives are implemented
by a FIPS-validated module.
Go can use the Google FIPS module. The boringcrypto
branch of the Go standard library uses the BoringSSL
FIPS module to implement crypto. primitives like AES
or SHA256.
We only keep github.com/minio/sha256-simd when computing
the content-SHA256 of an object. Therefore, this commit
relies on a build tag `fips`.
When MinIO is compiled without the `fips` flag it will
use github.com/minio/sha256-simd. When MinIO is compiled
with the fips flag (go build --tags "fips") then MinIO
uses crypto/sha256 to compute the content-SHA256.
Instead of using O_SYNC, we are better off using O_DSYNC
instead since we are only ever interested in data to be
persisted to disk not the associated filesystem metadata.
For reads we ask customers to turn off noatime, but instead
we can proactively use O_NOATIME flag to avoid atime updates
upon reads.
This removes the Content-MD5 response header on Range requests in Azure
Gateway mode. The partial content MD5 doesn't match the full object MD5
in metadata.
This commit adds a new package `etag` for dealing
with S3 ETags.
Even though ETag is often viewed as MD5 checksum of
an object, handling S3 ETags correctly is a surprisingly
complex task. While it is true that the ETag corresponds
to the MD5 for the most basic S3 API operations, there are
many exceptions in case of multipart uploads or encryption.
In worse, some S3 clients expect very specific behavior when
it comes to ETags. For example, some clients expect that the
ETag is a double-quoted string and fail otherwise.
Non-AWS compliant ETag handling has been a source of many bugs
in the past.
Therefore, this commit adds a dedicated `etag` package that provides
functionality for parsing, generating and converting S3 ETags.
Further, this commit removes the ETag computation from the `hash`
package. Instead, the `hash` package (i.e. `hash.Reader`) should
focus only on computing and verifying the content-sha256.
One core feature of this commit is to provide a mechanism to
communicate a computed ETag from a low-level `io.Reader` to
a high-level `io.Reader`.
This problem occurs when an S3 server receives a request and
has to compute the ETag of the content. However, the server
may also wrap the initial body with several other `io.Reader`,
e.g. when encrypting or compressing the content:
```
reader := Encrypt(Compress(ETag(content)))
```
In such a case, the ETag should be accessible by the high-level
`io.Reader`.
The `etag` provides a mechanism to wrap `io.Reader` implementations
such that the `ETag` can be accessed by a type-check.
This technique is applied to the PUT, COPY and Upload handlers.
server startup code expects the object layer to properly
convert error into a proper type, so that in situations when
servers are coming up and quorum is not available servers
wait on each other.
using isServerResolvable for expiration can lead to chicken
and egg problems, a lock might expire knowingly when server
is booting up causing perpetual locks getting expired.
- In username search filter and username format variables we support %s for
replacing with the username.
- In group search filter we support %s for username and %d for the full DN of
the username.
root-disk implemented currently had issues where root
disk partitions getting modified might race and provide
incorrect results, to avoid this lets rely again back on
DeviceID and match it instead.
In-case of containers `/data` is one such extra entity that
needs to be verified for root disk, due to how 'overlay'
filesystem works and the 'overlay' presents a completely
different 'device' id - using `/data` as another entity
for fallback helps because our containers describe 'VOLUME'
parameter that allows containers to automatically have a
virtual `/data` that points to the container root path this
can either be at `/` or `/var/lib/` (on different partition)
also additionally make sure errors during deserializer closes
the reader with right error type such that Write() end
actually see the final error, this avoids a waitGroup usage
and waiting.
reduce the page-cache pressure completely by moving
the entire read-phase of our operations to O_DIRECT,
primarily this is going to be very useful for chatty
metadata operations such as listing, scanner, ilm, healing
like operations to avoid filling up the page-cache upon
repeated runs.
since we have changed our default envs to MINIO_ROOT_USER,
MINIO_ROOT_PASSWORD this was not supported by minio-go
credentials package, update minio-go to v7.0.10 for this
support. This also addresses few bugs related to users
had to specify AWS_ACCESS_KEY_ID as well to authenticate
with their S3 backend if they only used MINIO_ROOT_USER.
We can use this metric to check if there are too many S3 clients in the
queue and could explain why some of those S3 clients are timing out.
```
minio_s3_requests_waiting_total{server="127.0.0.1:9000"} 9981
```
If max_requests is 10000 then there is a strong possibility that clients
are timing out because of the queue deadline.
If the periodic `case <-t.C:` save gets held up for a long time it will end up
synchronize all disk writes for saving the caches.
We add jitter to per set writes so they don't sync up and don't hold a
lock for the write, since it isn't needed anyway.
If an outage prevents writes for a long while we also add individual
waits for each disk in case there was a queue.
Furthermore limit the number of buffers kept to 2GiB, since this could get
huge in large clusters. This will not act as a hard limit but should be enough
for normal operation.
in the case of active-active replication.
This PR also has the following changes:
- add docs on replication design
- fix corner case of completing versioned delete on a delete marker
when the target is down and `mc rm --vid` is performed repeatedly. Instead
the version should still be retained in the `PENDING|FAILED` state until
replication sync completes.
- remove `s3:Replication:OperationCompletedReplication` and
`s3:Replication:OperationFailedReplication` from ObjectCreated
events type
currently crawler waits for an entire readdir call to
return until it processes usage, lifecycle, replication
and healing - instead we should pass the applicator all
the way down to avoid building any special stack for all
the contents in a single directory.
This allows for
- no need to remember the entire list of entries per directory
before applying the required functions
- no need to wait for entire readdir() call to finish before
applying the required functions
This PR fixes
- allow 's3:versionid` as a valid conditional for
Get,Put,Tags,Object locking APIs
- allow additional headers missing for object APIs
- allow wildcard based action matching
additionally simply timedValue to have RWMutex
to avoid concurrent calls to DiskInfo() getting
serialized, this has an effect on all calls that
use GetDiskInfo() on the same disks.
Such as getOnlineDisks, getOnlineDisksWithoutHealing
The function used for getting host information
(host.SensorsTemperaturesWithContext) returns warnings in some cases.
Returning with error in such cases means we miss out on the other useful
information already fetched (os info).
If the OS info has been succesfully fetched, it should always be
included in the output irrespective of whether the other data (CPU
sensors, users) could be fetched or not.
To avoid large delays in metacache cleanup, use rename
instead of recursive delete calls, renames are cheaper
move the content to minioMetaTmpBucket and then cleanup
this folder once in 24hrs instead.
If the new cache can replace an existing one, we should
let it replace since that is currently being saved anyways,
this avoids pile up of 1000's of metacache entires for
same listing calls that are not necessary to be stored
on disk.
Skip notifications on objects that might have had
an error during deletion, this also avoids unnecessary
replication attempt on such objects.
Refactor some places to make sure that we have notified
the client before we
- notify
- schedule for replication
- lifecycle etc.
continuation of PR#11491 for multiple server pools and
bi-directional replication.
Moving proxying for GET/HEAD to handler level rather than
server pool layer as this was also causing incorrect proxying
of HEAD.
Also fixing metadata update on CopyObject - minio-go was not passing
source version ID in X-Amz-Copy-Source header
filter out relevant objects for each pool to
avoid calling, further delete operations on
subsequent pools where some of these objects
might not exist.
This is mainly useful to avoid situations
during bi-directional bucket replication.
top-level options shouldn't be passed down for
GetObjectInfo() while verifying the objects in
different pools, this is to make sure that
we always get the value from the pool where
the object exists.
This change moves away from a unified constructor for plaintext and encrypted
usage. NewPutObjReader is simplified for the plain-text reader use. For
encrypted reader use, WithEncryption should be called on an initialized PutObjReader.
Plaintext:
func NewPutObjReader(rawReader *hash.Reader) *PutObjReader
The hash.Reader is used to provide payload size and md5sum to the downstream
consumers. This is different from the previous version in that there is no need
to pass nil values for unused parameters.
Encrypted:
func WithEncryption(encReader *hash.Reader,
key *crypto.ObjectKey) (*PutObjReader, error)
This method sets up encrypted reader along with the key to seal the md5sum
produced by the plain-text reader (already setup when NewPutObjReader was
called).
Usage:
```
pReader := NewPutObjReader(rawReader)
// ... other object handler code goes here
// Prepare the encrypted hashed reader
pReader, err = pReader.WithEncryption(encReader, objEncKey)
```
NoncurrentVersionExpiry can remove single delete markers according to
S3 spec:
```
The NoncurrentVersionExpiration action in the same Lifecycle
configuration removes noncurrent objects 30 days after they become
noncurrent. Thus, in this example, all object versions are permanently
removed 90 days after object creation. You will have expired object
delete markers, but Amazon S3 detects and removes the expired object
delete markers for you.
```
Collection of SMART information doesn't work in certain scenarios e.g.
in a container based setup. In such cases, instead of returning an error
(without any data), we should only set the error on the smartinfo
struct, so that other important drive hw info like device, mountpoint,
etc is retained in the output.
The code inside the `hotfix` taget is overriding the values set at the
beginning of the Makefile affecting other make targets as well.
For example, running `TAG=mytag make docker` also ends up tagging
the docker image as a hotfix instead of `mytag`.
Using the `eval` function inside the `hotfix` target fixes this.
during rolling upgrade, provide a more descriptive error
message and discourage rolling upgrade in such situations,
allowing users to take action.
additionally also rename `slashpath -> pathutil` to avoid
a slighly mis-pronounced usage of `path` package.
When lifecycle decides to Delete an object and not a version in a
versioned bucket, the code should create a delete marker and not
removing the scanned version.
This commit fixes the issue.
The connections info of the processes takes up a huge amount of space,
and is not important for adding any useful health checks. Removing it
will significantly reduce the size of the subnet health report.
- lock maintenance loop was incorrectly sleeping
as well as using ticker badly, leading to
extra expiration routines getting triggered
that could flood the network.
- multipart upload cleanup should be based on
timer instead of ticker, to ensure that long
running jobs don't get triggered twice.
- make sure to get right lockers for object name
Replaces #11449
Does concurrent healing but limits concurrency to 50 buckets.
Aborts on first error.
`errgroup.Group` is extended to facilitate this in a generic way.
We use multiple libraries in health info, but the returned error does
not indicate exactly what library call is failing, hence adding named
tags to returned errors whenever applicable.
After recent refactor where lifecycle started to rely on ObjectInfo to
make decisions, it turned out there are some issues calculating
Successor Modtime and NumVersions, hence the lifecycle is not working as
expected in a versioning bucket in some cases.
This commit fixes the behavior.
When a directory object is presented as a `prefix`
param our implementation tend to only list objects
present common to the `prefix` than the `prefix` itself,
to mimic AWS S3 like flat key behavior this PR ensures
that if `prefix` is directory object, it should be
automatically considered to be part of the eventual
listing result.

This commit refactors the SSE implementation and add
S3-compatible SSE-KMS context handling.
SSE-KMS differs from SSE-S3 in two main aspects:
1. The client can request a particular key and
specify a KMS context as part of the request.
2. The ETag of an SSE-KMS encrypted object is not
the MD5 sum of the object content.
This commit only focuses on the 1st aspect.
A client can send an optional SSE context when using
SSE-KMS. This context is remembered by the S3 server
such that the client does not have to specify the
context again (during multipart PUT / GET / HEAD ...).
The crypto. context also includes the bucket/object
name to prevent renaming objects at the backend.
Now, AWS S3 behaves as following:
- If the user does not provide a SSE-KMS context
it does not store one - resp. does not include
the SSE-KMS context header in the response (e.g. HEAD).
- If the user specifies a SSE-KMS context without
the bucket/object name then AWS stores the exact
context the client provided but adds the bucket/object
name internally. The response contains the KMS context
without the bucket/object name.
- If the user specifies a SSE-KMS context with
the bucket/object name then AWS again stores the exact
context provided by the client. The response contains
the KMS context with the bucket/object name.
This commit implements this behavior w.r.t. SSE-KMS.
However, as of now, no such object can be created since
the server rejects SSE-KMS encryption requests.
This commit is one stepping stone for SSE-KMS support.

This commit fixes a bug in the S3 gateway that causes
GET requests to fail when the object is encrypted by the
gateway itself.
The gateway was not able to GET the object since it always
specified a `If-Match` pre-condition checking that the object
ETag matches an expected ETag - even for encrypted ETags.
The problem is that an encrypted ETag will never match the ETag
computed by the backend causing the `If-Match` pre-condition
to fail.
This commit fixes this by not sending an `If-Match` header when
the ETag is encrypted. This is acceptable because:
1. A gateway-encrypted object consists of two objects at the backend
and there is no way to provide a concurrency-safe implementation
of two consecutive S3 GETs in the deployment model of the S3
gateway.
Ref: S3 gateways are self-contained and isolated - and there may
be multiple instances at the same time (no lock across
instances).
2. Even if the data object changes (concurrent PUT) while gateway
A has download the metadata object (but not issued the GET to
the data object => data race) then we don't return invalid data
to the client since the decryption (of the currently uploaded data)
will fail - given the metadata of the previous object.
Currently, it is not possible to create a delete-marker when xl.meta
does not exist (no version is created for that object yet). This makes a
problem for replication and mc mirroring with versioning enabled.
This also follows S3 specification.
github.com/ncw/directio doesn't support OpenBSD, but OpenBSD has

This commit deprecates the native Hashicorp Vault
support and removes the legacy Vault documentation.
The native Hashicorp Vault documentation is marked as
outdated and deprecated for over a year now. We give
another 6 months before we start removing Hashicorp Vault
support and show a deprecation warning when a MinIO server
starts with a native Vault configuration.
currently we had a restriction where older setups would
need to follow previous style of "stripe" count being same

expanded for older setups with newer constraints of
common parity ratio.
In PR #11165 due to incorrect proxying for 2

yet replicated
Additionally, fix metadata comparisons when
deciding to do full replication vs metadata copy.
fixes#11340
Previously we added heal trigger when bit-rot checks
failed, now extend that to support heal when parts
are not found either. This healing gets only triggered
if we can successfully decode the object i.e read
quorum is still satisfied for the object.
under large deployments loading credentials might be
time consuming, while this is okay and we will not
respond quickly for `mc admin user list` like queries
but it is possible to support `mc admin user info`
just like how we handle authentication by fetching
the user directly from persistent store.
additionally support service accounts properly,
reloaded from etcd during watch() - this was missing
This PR is also half way remedy for #11305
This change allows the MinIO server to be configured with a special (read-only)
LDAP account to perform user DN lookups.
The following configuration parameters are added (along with corresponding
environment variables) to LDAP identity configuration (under `identity_ldap`):
- lookup_bind_dn / MINIO_IDENTITY_LDAP_LOOKUP_BIND_DN
- lookup_bind_password / MINIO_IDENTITY_LDAP_LOOKUP_BIND_PASSWORD
- user_dn_search_base_dn / MINIO_IDENTITY_LDAP_USER_DN_SEARCH_BASE_DN
- user_dn_search_filter / MINIO_IDENTITY_LDAP_USER_DN_SEARCH_FILTER
This lookup-bind account is a service account that is used to lookup the user's
DN from their username provided in the STS API. When configured, searching for
the user DN is enabled and configuration of the base DN and filter for search is
required. In this "lookup-bind" mode, the username format is not checked and must
not be specified. This feature is to support Active Directory setups where the
DN cannot be simply derived from the username.
When the lookup-bind is not configured, the old behavior is enabled: the minio
server performs LDAP lookups as the LDAP user making the STS API request and the
username format is checked and configuring it is required.
STS tokens can be obtained by using local APIs
once the remote JWT token is presented, current
code was not validating the incoming token in the
first place and was incorrectly making a network
operation using that token.
For the most part this always works without issues,
but under adversarial scenarios it exposes client
to hand-craft a request that can reach internal
services without authentication.
This kind of proxying should be avoided before
validating the incoming token.
The user can see __XLDIR__ prefix in mc admin heal when the command
heals an empty object with a trailing slash. This commit decodes the
name of the object before sending it back to the upper level.
In-case user enables O_DIRECT for reads and backend does
not support it we shall proceed to turn it off instead
and print a warning. This validation avoids any unexpected
downtimes that users may incur.
DNSCache dialer is a global value initialized in
init(), whereas `go` keeps `var =` before `init()`
, also we don't need to keep proxy routers as
global entities - register the forwarder as
necessary to avoid crashes.
```
mc admin config set alias/ storage_class standard=EC:3
```
should only succeed if parity ratio is valid for all
server pools, if not we should fail proactively.
This PR also needs to bring other changes now that
we need to cater for variadic drive counts per pool.

- GetObjectWithPartNumber()
- CopyObjectPartWithOffsets()
- CopyObjectWithMetadata()
- PutObjectPart,PutObject with truncated streams

Delete marker can have `metaSys` set to nil, that
can lead to crashes after the delete marker has
been healed.
Additionally also fix isObjectDangling check
for transitioned objects, that do not have parts
should be treated similar to Delete marker.
During expansion we need to validate if
- new deployment is expanded with newer constraints
- existing deployment is expanded with older constraints
- multiple server pools rejected if they have different
deploymentID and distribution algo
to verify moving content and preserving legacy content,
we have way to detect the objects through readdir()
this path is not necessary for most common cases on
newer setups, avoid readdir() to save multiple system
calls.
also fix the CheckFile behavior for most common
use case i.e without legacy format.
If an erasure set had a drive replacement recently, we don't
need to attempt healing on another drive with in the same erasure
set - this would ensure we do not double heal the same content
and also prioritizes usage for such an erasure set to be calculated
sooner.
For objects with `N` prefix depth, this PR reduces `N` such network
operations by converting `CheckFile` into a single bulk operation.
Reduction in chattiness here would allow disks to be utilized more
cleanly, while maintaining the same functionality along with one
extra volume check stat() call is removed.
Update tests to test multiple sets scenario
Fixes support for using multiple base DNs for user search in the LDAP directory
allowing users from different subtrees in the LDAP hierarchy to request
credentials.
- The username in the produced credentials is now the full DN of the LDAP user
to disambiguate users in different base DNs.
parentDirIsObject is not using set level understanding
to check for parent objects, without this it can lead to
objects that can actually reside on a separate set as
objects and would conflict.
Current implementation requires server pools to have
same erasure stripe sizes, to facilitate same SLA
and expectations.
This PR allows server pools to be variadic, i.e they
do not have to be same erasure stripe sizes - instead
they should have SLA for parity ratio.
If the parity ratio cannot be guaranteed by the new
server pool, the deployment is rejected i.e server
pool expansion is not allowed.
This ensures that all the prometheus monitoring and usage

A lot of memory is consumed when uploading small files in parallel, use

Synchronous replication can be enabled by setting the --sync
flag while adding a remote replication target.
This PR also adds proxying on GET/HEAD to another node in a
active-active replication setup in the event of a 404 on the current node.
This PR refactors the way we use buffers for O_DIRECT and
to re-use those buffers for messagepack reader writer.
After some extensive benchmarking found that not all objects
have this benefit, and only objects smaller than 64KiB see
this benefit overall.
Benefits are seen from almost all objects from
1KiB - 32KiB
Beyond this no objects see benefit with bulk call approach
as the latency of bytes sent over the wire v/s streaming
content directly from disk negate each other with no
remarkable benefits.
All other optimizations include reuse of msgp.Reader,
msgp.Writer using sync.Pool's for all internode calls.
30 seconds white spaces is long for some setups which time out when no
read activity in short time, reduce the subnet health white space ticker
to 5 seconds, since it has no cost at all.
Use separate sync.Pool for writes/reads
Avoid passing buffers for io.CopyBuffer()
if the writer or reader implement io.WriteTo or io.ReadFrom
respectively then its useless for sync.Pool to allocate
buffers on its own since that will be completely ignored
by the io.CopyBuffer Go implementation.
Improve this wherever we see this to be optimal.
This allows us to be more efficient on memory usage.
```
385 // copyBuffer is the actual implementation of Copy and CopyBuffer.
386 // if buf is nil, one is allocated.
387 func copyBuffer(dst Writer, src Reader, buf []byte) (written int64, err error) {
388 // If the reader has a WriteTo method, use it to do the copy.
389 // Avoids an allocation and a copy.
390 if wt, ok := src.(WriterTo); ok {
391 return wt.WriteTo(dst)
392 }
393 // Similarly, if the writer has a ReadFrom method, use it to do the copy.
394 if rt, ok := dst.(ReaderFrom); ok {
395 return rt.ReadFrom(src)
396 }
```
From readahead package
```
// WriteTo writes data to w until there's no more data to write or when an error occurs.
// The return value n is the number of bytes written.
// Any error encountered during the write is also returned.
func (a *reader) WriteTo(w io.Writer) (n int64, err error) {
if a.err != nil {
return 0, a.err
}
n = 0
for {
err = a.fill()
if err != nil {
return n, err
}
n2, err := w.Write(a.cur.buffer())
a.cur.inc(n2)
n += int64(n2)
if err != nil {
return n, err
}

with changes present to automatically throttle crawler
at runtime, there is no need to have an environment
value to disable crawling. crawling is a fundamental
piece for healing, lifecycle and many other features
there is no good reason anyone would need to disable
this on a production system.

globalSubscribers.NumSubscribers() is heavily used in S3 requests and it

Rewrite parentIsObject() function. Currently if a client uploads
a/b/c/d, we always check if c, b, a are actual objects or not.
The new code will check with the reverse order and quickly quit if
the segment doesn't exist.
So if a, b, c in 'a/b/c' does not exist in the first place, then returns
false quickly.
The only purpose of check-dir flag in
ReadVersion is to return 404 when
an object has xl.meta but without data.
This is causing an extract call to the disk
which can be penalizing in case of busy system
where disks receive many concurrent access.
mc admin trace does not show the correct handler name in the output: it
is printing `maxClients' for all handlers. The reason is that the wrong
order of handler wrapping.
Fixes two problems
- Double healing when bitrot is enabled, instead heal attempt
once in applyActions() before lifecycle is applied.
- If applyActions() is successful and getSize() returns proper
value, then object is accounted for and should be removed
from the oldCache namespace map to avoid double heal attempts.
main reason is that HealObjects starts a recursive listing
for each object, this can be a really really long time on
large namespaces instead avoid recursive listing just
perform HealObject() instead at the prefix.
delete's already handle purging dangling content, we
don't need to achieve this by doing recursive listing,
this in-turn can delay crawling significantly.
Optimizations include
- do not write the metacache block if the size of the
block is '0' and it is the first block - where listing
is attempted for a transient prefix, this helps to
avoid creating lots of empty metacache entries for
`minioMetaBucket`
- avoid the entire initialization sequence of cacheCh
, metacacheBlockWriter if we are simply going to skip
them when discardResults is set to true.
- No need to hold write locks while writing metacache
blocks - each block is unique, per bucket, per prefix
and also is written by a single node.
current implementation was incorrect, it in-fact
assumed only read quorum number of disks. in-fact
that value is only meant for read quorum good entries
from all online disks.
This PR fixes this behavior properly.
This commit refactors the code in `cmd/crypto`
and separates SSE-S3, SSE-C and SSE-KMS.
This commit should not cause any behavior change
except for:
- `IsRequested(http.Header)`
which now returns the requested type {SSE-C, SSE-S3,
SSE-KMS} and does not consider SSE-C copy headers.
However, SSE-C copy headers alone are anyway not valid.
Additional cases handled
- fix address situations where healing is not
triggered on failed writes and deletes.
- consider object exists during listing when
metadata can be successfully decoded.
always find the right set of online peers for remote listing,
this may have an effect on listing if the server is down - we
should do this to avoid always performing transient operations
on bucket->peerClient that is permanently or down for a long
period.
additionally also configure http2 healthcheck
values to quickly detect unstable connections
and let them timeout.
also use single transport for proxying requests
with missing nextMarker with delimiter based listing,
top level prefixes beyond 4500 or max-keys value
wouldn't be sent back for client to ask for the next
batch.
reproduced at a customer deployment, create prefixes
as shown below
```
for year in $(seq 2017 2020)
do
for month in {01..12}
do for day in {01..31}
do
mc -q cp file myminio/testbucket/dir/day_id=$year-$month-$day/;
done
done
done
```
Then perform
```
aws s3api --profile minio --endpoint-url http://localhost:9000 list-objects \
--bucket testbucket --prefix dir/ --delimiter / --max-keys 1000
```
You shall see missing NextMarker, this would disallow listing beyond max-keys
requested and also disallow beyond 4500 (maxKeyObjectList) prefixes being listed
because client wouldn't know the NextMarker available.
This PR addresses this situation properly by making the implementation
more spec compatible. i.e NextMarker in-fact can be either an object, a prefix
with delimiter depending on the input operation.
This issue was introduced after the list caching changes and has been present
for a while.
regression was introduced by cce5d7152a
which incorrectly implemented the tests and fixed a wrong requirement,
CompleteMultipart should never succeed in the tests.
issue was introduced in #11106 the following
pattern
<-t.C // timer fired
if !t.Stop() {
<-t.C // timer hangs
}
Seems to hang at the last `t.C` line, this
issue happens because a fired timer cannot be
Stopped() anymore and t.Stop() returns `false`
leading to confusing state of usage.
Refactor the code such that use timers appropriately
with exact requirements in place.
Both Azure & S3 gateways call for object information before returning
the stream of the object, however, the object content/length could be
modified meanwhile, which means it can return a corrupted object.
Use ETag to ensure that the object was not modified during the GET call
Currently, the test doesn't complete nor abort the multipart upload
after tesing the list operation. It caused the `cleanup()` to fail since
the object can't not be deleted which causes the bucket deletion to
fail.
This PR adds a `CompleteMultipartUpload` call to commit the object so
the cleanup can successfully delete the object and bucket.
crawler should only ListBuckets once not for each serverPool,
buckets are same across all pools, across sets and ListBuckets
always returns an unified view, once list buckets returns
sort it by create time to scan the latest buckets earlier
with the assumption that latest buckets would have lesser
content than older buckets allowing them to be scanned faster
and also to be able to provide more closer to latest view.
When searching the caches don't copy the ids, instead inline the loop.
```
Benchmark_bucketMetacache_findCache-32 19200 63490 ns/op 8303 B/op 5 allocs/op
Benchmark_bucketMetacache_findCache-32 20338 58609 ns/op 111 B/op 4 allocs/op
```
Add a reasonable, but still the simplistic benchmark.
Bonus - make nicer zero alloc logging
With new refactor of bucket healing, healing bucket happens
automatically including its metadata, there is no need to
redundant heal buckets also in ListBucketsHeal remove
it.
optimization mainly to avoid listing the entire
`.minio.sys/buckets/.minio.sys` directory, this
can get really huge and comes in the way of startup
routines, contents inside `.minio.sys/buckets/.minio.sys`
are rather transient and not necessary to be healed.
Tests environments (go test or manual testing) should always consider
the passed disks are root disks and should not rely on disk.IsRootDisk()
function. The reason is that this latter can return a false negative
when called in a busy system. However, returning a false negative will
only occur in a testing environment and not in a production, so we can
accept this trade-off for now.
Perform cleanup operations on copied data. Avoids read locking
data while determining which caches to keep.
Also, reduce the log(N*N) operation to log(N*M) where M caches
with the same root or below when checking potential replacements.
This refactor is done for few reasons below
- to avoid deadlocks in scenarios when number
of nodes are smaller < actual erasure stripe
count where in N participating local lockers
can lead to deadlocks across systems.
- avoids expiry routines to run 1000 of separate
network operations and routes per disk where
as each of them are still accessing one single
local entity.
- it is ideal to have since globalLockServer
per instance.
- In a 32node deployment however, each server
group is still concentrated towards the
same set of lockers that partipicate during
the write/read phase, unlike previous minio/dsync
implementation - this potentially avoids send
32 requests instead we will still send at max
requests of unique nodes participating in a
write/read phase.
- reduces overall chattiness on smaller setups.
The bucket forwarder handler considers MakeBucket to be always local but

till now we used to match the inode number of the root
drive and the drive path minio would use, if they match

this may not be true in all situations such as running

disk detection might fail.
partNumber was miscalculting the start and end of parts when partNumber

Due to botched upstream renames of project repositories
and incomplete migration to go.mod support, our current
dependency version of `go.mod` had bugs i.e it was

which leads to some rare bugs

fixes#10497
- accountInfo API that returns information about
user, access to buckets and the size per bucket
- addUser - user is allowed to change their secretKey
- getUserInfo - returns user info if the incoming
is the same user requesting their information
In some cases a writer could be left behind unclosed, leaking compression blocks.
Always close and set compression concurrency to 2 which should be fine to keep up.
Due to https://github.com/philhofer/fwd/issues/20 when skipping a metadata entry that is >2048 bytes and the buffer is full (2048 bytes) the skip will fail with `io.ErrNoProgress`.
Enlarge the buffer so we temporarily make this much more unlikely.
If it still happens we will have to rewrite the skips to reads.

dangling object when deleted means object doesn't exist
anymore, so we should return appropriate errors, this
allows crawler heal to ensure that it removes the tracker
for dangling objects.
AZURE_STORAGE_ACCOUNT and AZURE_STORAGE_KEY are used in

it is possible to set them if you want the gateway's own credentials to be

dangling objects when removed `mc admin heal -r` or crawler
auto heal would incorrectly return error - this can interfere
with usage calculation as the entry size for this would be
returned as `0`, instead upon success use the resultant
object size to calculate the final size for the object
and avoid reporting this in the log messages
Also do not set ObjectSize in healResultItem to be '-1'
this has an effect on crawler metrics calculating 1 byte
less for objects which seem to be missing their `xl.meta`

useful cache so in that case, we will list all objects/folders.
"hw.physmem" only reports reasonable results on 32 bit systems and is
kept to not break binary compatibility. On other systems, it reports
"-1". "hw.phymem64" reports reasonable results on all systems.
MinIO getHwPhysmem method currently uses the deprecated
"hw.physmem" key which results in a parse error (due to the -1).
This pull request asks for changing this. The change was tested
successfully on NetBSD/amd64 9.1.
Add shortcut for `APN/1.0 Veeam/1.0 Backup/10.0`
It requests unique blocks with a specific prefix. We skip
scanning the parent directory for more objects matching the prefix.
Allow each crawler operation to sleep up to 10 seconds on very heavily loaded systems.
This will of course make minimum crawler speed less, but should be more effective at stopping.
Delete marker replication is implemented for V2
configuration specified in AWS spec (though AWS
allows it only in the V1 configuration).
This PR also brings in a MinIO only extension of
replicating permanent deletes, i.e. deletes specifying
version id are replicated to target cluster.
This will make the health check clients 'silent'.
Use `IsNetworkOrHostDown` determine if network is ok so it mimics the functionality in the actual client.
this is needed such that we make sure to heal the
users, policies and bucket metadata right away as
we do listing based on list cache which only lists
'3' sufficiently good drives, to avoid possibly
losing access to these users upon upgrade make
sure to heal them.
If a scanning server shuts down unexpectedly we may have "successful" caches that are incomplete on a set.
In this case mark the cache with an error so it will no longer be handed out.
Add `MINIO_API_EXTEND_LIST_CACHE_LIFE` that will extend
the life of generated caches for a while.
This changes caches to remain valid until no updates have been
received for the specified time plus a fixed margin.
This also changes the caches from being invalidated when the *first*
set finishes until the *last* set has finished plus the specified time
has passed.
Similar to #10775 for fewer memory allocations, since we use
getOnlineDisks() extensively for listing we should optimize it
further.
Additionally, remove all unused walkers from the storage layer
A new field called AccessKey is added to the ReqInfo struct and populated.
Because ReqInfo is added to the context, this allows the AccessKey to be
accessed from 3rd-party code, such as a custom ObjectLayer.

On extremely long running listings keep the transient list 15 minutes after last update instead of using start time.
Also don't do overlap checks on transient lists.
Add trashcan that keeps recently updated lists after bucket deletion.
All caches were deleted once a bucket was deleted, so caches still running would report errors. Now they are canceled.
Fix `.minio.sys` not being transient.
Bonus fixes, remove package retry it is harder to get it
right, also manage context remove it such that we don't have
to rely on it anymore instead use a simple Jitter retry.
WriteAll saw 127GB allocs in a 5 minute timeframe for 4MiB buffers
used by `io.CopyBuffer` even if they are pooled.
Since all writers appear to write byte buffers, just send those
instead and write directly. The files are opened through the `os`
package so they have no special properties anyway.
This removes the alloc and copy for each operation.
REST sends content length so a precise alloc can be made.
this reduces allocations in order of magnitude
Also, revert "erasure: delete dangling objects automatically (#10765)"
affects list caching should be investigated.
Add store and a forward option for a single part
uploads when an async mode is enabled with env
MINIO_CACHE_COMMIT=writeback
It defaults to `writethrough` if unspecified.
Bonus fixes, we do not need reload format anymore
as the replaced drive is healed locally we only need
to ensure that drive heal reloads the drive properly.
We preserve the UUID of the original order, this means
that the replacement in `format.json` doesn't mean that
the drive needs to be reloaded into memory anymore.

Gist of improvements:
* Cross-server caching and listing will use the same data across servers and requests.
* Lists can be arbitrarily resumed at a constant speed.
* Metadata for all files scanned is stored for streaming retrieval.
* The existing bloom filters controlled by the crawler is used for validating caches.
* Concurrent requests for the same data (or parts of it) will not spawn additional walkers.
* Listing a subdirectory of an existing recursive cache will use the cache.
* All listing operations are fully streamable so the number of objects in a bucket no
longer dictates the amount of memory.
* Listings can be handled by any server within the cluster.
* Caches are cleaned up when out of date or superseded by a more recent one.
only newly replaced drives get the new `format.json`,
this avoids disks reloading their in-memory reference
format, ensures that drives are online without
reloading the in-memory reference format.
keeping reference format in-tact means UUIDs
never change once they are formatted.
lockers currently might leave stale lockers,
in unknown ways waiting for downed lockers.

Test TestDialContextWithDNSCacheRand was failing sometimes because it depends

Allow requests to come in for users as soon as object

Go stdlib resolver doesn't support caching DNS
resolutions, since we compile with CGO disabled
we are more probe to DNS flooding for all network
calls to resolve for DNS from the DNS server.
Under various containerized environments such as
VMWare this becomes a problem because there are
no DNS caches available and we may end up overloading
the kube-dns resolver under concurrent I/O.
To circumvent this issue implement a DNSCache resolver
which resolves DNS and caches them for around 10secs
with every 3sec invalidation attempted.
connect disks pre-emptively upon startup, to ensure we have

we need to do this to avoid long wait times for server to

fashion
Only use dynamic delays for the crawler. Even though the max wait was 1 second the number
of waits could severely impact crawler speed.
Instead of relying on a global metric, we use the stateless local delays to keep the crawler
running at a speed more adjusted to current conditions.
The only case we keep it is before bitrot checks when enabled.
This PR fixes a hang which occurs quite commonly at higher concurrency
by allowing following changes
- allowing lower connections in time_wait allows faster socket open's
- lower idle connection timeout to ensure that we let kernel

- increase somaxconn to 4096 instead of 2048 to allow larger tcp
syn backlogs.

This commit fixes a misuse of the `http.ResponseWriter.WriteHeader`.
A caller should **either** call `WriteHeader` exactly once **or**
write to the response writer and causing an implicit 200 OK.
Writing the response headers more than once causes a `http: superfluous
response.WriteHeader call` log message. This commit fixes this
by preventing a 2nd `WriteHeader` call being forwarded to the underlying
`ResponseWriter`.

After #10594 let's invalidate the bloom filters to force the next cycles to go through all data.
There is a small chance that the linked PR could have caused missing bloom filter data.
This will invalidate the current bloom filters and make the crawler go through everything.
Routing using on source IP if found. This should distribute
the listing load for V1 and versioning on multiple nodes
evenly between different clients.
If source IP is not found from the http request header, then falls back

context canceled errors bubbling up from the network

a health check routine avoid this potential occurrence.
isEnded() was incorrectly calculating if the current healing sequence is
ended or not. h.currentStatus.Items could be empty if healing is very
slow and mc admin heal consumed all items.
As the bulk/recursive delete will require multiple connections to open at an instance,
The default open connections limit will be reached which results in the following error
```FATAL: sorry, too many clients already```
By setting the open connections to a reasonable value - `2`, We ensure that the max open connections
will not be exhausted and lie under bounds.
The queries are simple inserts/updates/deletes which is operational and sufficient with the
the maximum open connection limit is 2.
Fixes#10553
Allow user configuration for MaxOpenConnections
It is possible the heal drives are not reported from
the maintenance check because the background heal
state simply relied on the `format.json` for capturing
unformatted drives. It is possible that drives might
be still healing - make sure that applications which
rely on cluster health check respond back this detail.
Also, revamp the way ListBuckets work make few portions
of the healing logic parallel
- walk objects for healing disks in parallel
- collect the list of buckets in parallel across drives
- provide consistent view for listBuckets()
Healing was not working correctly in the distributed mode because
errFileVersionNotFound was not properly converted in storage rest
client.
Besides, fixing the healing delete marker is not working as expected.

It was observed in VMware vsphere environment during a
pod replacement, `mc admin info` might report incorrect
offline nodes for the replaced drive. This issue eventually
goes away but requires quite a lot of time for all servers
to be in sync.
This PR fixes this behavior properly.
If the ILM document requires removing noncurrent versions, the
the server should be able to remove 'null' versions as well.
'null' versions are created when versioning is not enabled
or suspended.
The entire encryption layer is dependent on the fact that
KMS should be configured for S3 encryption to work properly
and we only support passing the headers as is to the backend
for encryption only if KMS is configured.
Make sure that this predictability is maintained, currently
the code was allowing encryption to go through and fail
at later to indicate that KMS was not configured. We should
simply reply "NotImplemented" if KMS is not configured, this
allows clients to simply proceed with their tests.
This is to ensure that Go contexts work properly, after some
interesting experiments I found that Go net/http doesn't
cancel the context when Body is non-zero and hasn't been
read till EOF.
The following gist explains this, this can lead to pile up
of go-routines on the server which will never be canceled
and will die at a really later point in time, which can
simply overwhelm the server.
https://gist.github.com/harshavardhana/c51dcfd055780eaeb71db54f9c589150
To avoid this refactor the locking such that we take locks after we
have started reading from the body and only take locks when needed.
Also, remove contextReader as it's not useful, doesn't work as expected
context is not canceled until the body reaches EOF so there is no point
in wrapping it with context and putting a `select {` on it which
can unnecessarily increase the CPU overhead.
We will still use the context to cancel the lockers etc.
Additional simplification in the locker code to avoid timers
as re-using them is a complicated ordeal avoid them in
the hot path, since locking is very common this may avoid
lots of allocations.
This commit fixes the nats TLS tests by generating new certificates
(root CA, server and client) - each valid for 10y. The new certificates
don't have a common name (deprecated by X.509) but SANs instead.

only have a common name and no SAN. See: https://golang.org/doc/go1.15#commonname

```
When specifying the number of days in the NoncurrentVersionTransition
and NoncurrentVersionExpiration actions in a Lifecycle configuration,
note the following:
It is the number of days from when the version of the object becomes
noncurrent (that is, when the object is overwritten or deleted), that
Amazon S3 will perform the action on the specified object or objects.
Amazon S3 calculates the time by adding the number of days specified in
the rule to the time when the new successor version of the object is
created and rounding the resulting time to the next day midnight UTC.
For example, in your bucket, suppose that you have a current version of
an object that was created at 1/1/2014 10:30 AM UTC. If the new version
of the object that replaces the current version is created at 1/15/2014
10:30 AM UTC, and you specify 3 days in a transition rule, the
transition date of the object is calculated as 1/19/2014 00:00 UTC.

inconsistent drive healing when one of the drive is offline
while a new drive was replaced, this change is to ensure
that we can add the offline drive back into the mix by
healing it again.
Add context to all (non-trivial) calls to the storage layer.
Contexts are propagated through the REST client.
- `context.TODO()` is left in place for the places where it needs to be added to the caller.
- `endWalkCh` could probably be removed from the walkers, but no changes so far.
The "dangerous" part is that now a caller disconnecting *will* propagate down, so a
"delete" operation will now be interrupted. In some cases we might want to disconnect
this functionality so the operation completes if it has started, leaving the system in a cleaner state.
This commit refactors the certificate management implementation
in the `certs` package such that multiple certificates can be
specified at the same time. Therefore, the following layout of
the `certs/` directory is expected:
```
certs/
│
├─ public.crt
├─ private.key
├─ CAs/ // CAs directory is ignored
│ │
│ ...
│
├─ example.com/
│ │
│ ├─ public.crt
│ └─ private.key
└─ foobar.org/
│
├─ public.crt
└─ private.key
...
```
However, directory names like `example.com` are just for human
readability/organization and don't have any meaning w.r.t whether
a particular certificate is served or not. This decision is made based
on the SNI sent by the client and the SAN of the certificate.
***
The `Manager` will pick a certificate based on the client trying
to establish a TLS connection. In particular, it looks at the client
hello (i.e. SNI) to determine which host the client tries to access.
If the manager can find a certificate that matches the SNI it
returns this certificate to the client.
However, the client may choose to not send an SNI or tries to access
a server directly via IP (`https://<ip>:<port>`). In this case, we
cannot use the SNI to determine which certificate to serve. However,
we also should not pick "the first" certificate that would be accepted
by the client (based on crypto. parameters - like a signature algorithm)
because it may be an internal certificate that contains internal hostnames.
We would disclose internal infrastructure details doing so.
Therefore, the `Manager` returns the "default" certificate when the
client does not specify an SNI. The default certificate the top-level
`public.crt` - i.e. `certs/public.crt`.
This approach has some consequences:
- It's the operator's responsibility to ensure that the top-level
`public.crt` does not disclose any information (i.e. hostnames)
that are not publicly visible. However, this was the case in the
past already.
- Any other `public.crt` - except for the top-level one - must not
contain any IP SAN. The reason for this restriction is that the
Manager cannot match a SNI to an IP b/c the SNI is the server host
name. The entire purpose of SNI is to indicate which host the client
tries to connect to when multiple hosts run on the same IP. So, a
client will not set the SNI to an IP.
If we would allow IP SANs in a lower-level `public.crt` a user would
expect that it is possible to connect to MinIO directly via IP address
and that the MinIO server would pick "the right" certificate. However,
the MinIO server cannot determine which certificate to serve, and
therefore always picks the "default" one. This may lead to all sorts
of confusing errors like:
"It works if I use `https:instance.minio.local` but not when I use
`https://10.0.2.1`.
These consequences/limitations should be pointed out / explained in our
docs in an appropriate way. However, the support for multiple
certificates should not have any impact on how deployment with a single
certificate function today.

- do not fail the healthcheck if heal status
was not obtained from one of the nodes,
if many nodes fail then report this as a
catastrophic error.
- add "x-minio-write-quorum" value to match

- admin info now states if a drive is healing
where madmin.Disk.Healing is set to true
and madmin.Disk.State is "ok"
Currently, cache purges are triggered as soon as the low watermark is exceeded.
To reduce IO this should only be done when reaching the high watermark.
This simplifies checks and reduces all calls for a GC to go through
`dcache.diskSpaceAvailable(size)`. While a comment claims that
`dcache.triggerGC <- struct{}{}` was non-blocking I don't see how
that was possible. Instead, we add a 1 size to the queue channel
and use channel semantics to avoid blocking when a GC has
already been requested.
`bytesToClear` now takes the high watermark into account to it will
not request any bytes to be cleared until that is reached.
This commit reduces the retry delay when retrying a request
to a KES server by:
- reducing the max. jitter delay from 3s to 1.5s
- skipping the random delay when there are more KES endpoints
available.
If there are more KES endpoints we can directly retry to the request
by sending it to the next endpoint - as pointed out by @krishnasrinivas
- delete-marker should be created on a suspended bucket as `null`
- delete-marker should delete any pre-existing `null` versioned
object and create an entry `null`
When checking parts we already do a stat for each part.
Since we have the on disk size check if it is at least what we expect.
When checking metadata check if metadata is 0 bytes.
The `getNonLoopBackIP` may grab an IP from an interface that
doesn't allow binding (on Windows), so this test consistently fails.
We exclude that specific error.

This commit addresses a maintenance / automation problem when MinIO-KES
is deployed on bare-metal. In orchestrated env. the orchestrator (K8S)
will make sure that `n` KES servers (IPs) are available via the same DNS
name. There it is sufficient to provide just one endpoint.
ListObjectsV1 requests are actually redirected to a specific node,
depending on the bucket name. The purpose of this behavior was
to optimize listing.
However, the current code sends a Bad Gateway error if the
target node is offline, which is a bad behavior because it means
that the list request will fail, although this is unnecessary since
we can still use the current node to list as well (the default behavior
without using proxying optimization)
Currently, you can see mint fails when there is one offline node, after
this PR, mint will always succeed.
We can reduce this further in the future, but this is a good
value to keep around. With the advent of continuous healing,
we can be assured that namespace will eventually be
consistent so we are okay to avoid the necessity to
a list across all drives on all sets.
Bonus Pop()'s in parallel seem to have the potential to
wait too on large drive setups and cause more slowness
instead of gaining any performance remove it for now.
Also, implement load balanced reply for local disks,
ensuring that local disks have an affinity for
- cleanupStaleMultipartUploads()
If DiskInfo calls failed the information returned was used anyway
resulting in no endpoint being set.
This would make the drive be attributed to the local system since
`disk.Endpoint == disk.DrivePath` in that case.
Instead, if the call fails record the endpoint and the error only.
bonus make sure to ignore objectNotFound, and versionNotFound
errors properly at all layers, since HealObjects() returns
objectNotFound error if the bucket or prefix is empty.
When crawling never use a disk we know is healing.
Most of the change involves keeping track of the original endpoint on xlStorage
and this also fixes DiskInfo.Endpoint never being populated.
Heal master will print `data-crawl: Disk "http://localhost:9001/data/mindev/data2/xl1" is
Healing, skipping` once on a cycle (no more often than every 5m).
We should only enforce quotas if no error has been returned.
firstErr is safe to access since all goroutines have exited at this point.
If `firstErr` hasn't been set by something else return the context error if cancelled.
Keep dataUpdateTracker while goroutine is starting.
This will ensure the object is updated one `start` returns

I have built a fuzz test and it crashes heavily in seconds and will OOM shortly after.
It seems like supporting Parquet is basically a completely open way to crash the
server if you can upload a file and run s3 select on it.
Until Parquet is more hardened it is DISABLED by default since hostile
crafted input can easily crash the server.
If you are in a controlled environment where it is safe to assume no hostile
content can be uploaded to your cluster you can safely enable Parquet.
To enable Parquet set the environment variable `MINIO_API_SELECT_PARQUET=on`
while starting the MinIO server.
Furthermore, we guard parquet by recover functions.
newDynamicTimeout should be allocated once, in-case
of temporary locks in config and IAM we should
have allocated timeout once before the `for loop`
This PR doesn't fix any issue as such, but provides
enough dynamism for the timeout as per expectation.
Based on our previous conversations I assume we should send the version
id when healing an object.
Maybe we should even list object versions and heal all?
In a non recursive mode, issuing a list request where prefix
is an existing object with a slash and delimiter is a slash will
return entries in the object directory (data dir IDs)

use `/etc/hosts` instead of `/` to check for common
device id, if the device is same for `/etc/hosts`
and the --bind mount to detect root disks.
Bonus enhance healthcheck logging by adding maintenance
tags, for all messages.
adds a feature where we can fetch the MinIO
command-line remotely, this
is primarily meant to add some stateless
nature to the MinIO deployment in k8s
environments, MinIO operator would run a
webhook service endpoint
which can be used to fetch any environment
value in a generalized approach.
It is possible in situations when server was deployed
in asymmetric configuration in the past such as
```
minio server ~/fs{1...4}/disk{1...5}
```
Results in setDriveCount of 10 in older releases
but with fairly recent releases we have moved to
having server affinity which means that a set drive
count ascertained from above config will be now '4'
While the object layer make sure that we honor
`format.json` the storageClass configuration however
was by mistake was using the global value obtained
by heuristics. Which leads to prematurely using
lower parity without being requested by the an
administrator.
This PR fixes this behavior.
Bonus also fix a bug where we did not purge relevant
service accounts generated by rotating credentials
appropriately, service accounts should become invalid
as soon as its corresponding parent user becomes invalid.
Since service account themselves carry parent claim always
we would never reach this problem, as the access get
rejected at IAM policy layer.

when source and destination are same and versioning is enabled
on the destination bucket - we do not need to re-create the entire
object once again to optimize on space utilization.
Cases this PR is not supporting
- any pre-existing legacy object will not
be preserved in this manner, meaning a new
dataDir will be created.
- key-rotation and storage class changes
of course will never re-use the dataDir
conflicting files can exist on FS at
`.minio.sys/buckets/testbucket/policy.json/`, this is an
expected valid scenario for FS mode allow it to work,
i.e ignore and move forward
With reduced parity our write quorum should be same
as read quorum, but code was still assuming
```
readQuorum+1
```
In all situations which is not necessary.
Generalize replication target management so
that remote targets for a bucket can be
managed with ARNs. `mc admin bucket remote`
command will be used to manage targets.
Context timeout might race on each other when timeouts are lower
i.e when two lock attempts happened very quickly on the same resource
and the servers were yet trying to establish quorum.
This situation can lead to locks held which wouldn't be unlocked
and subsequent lock attempts would fail.
This would require a complete server restart. A potential of this
issue happening is when server is booting up and we are trying
to hold a 'transaction.lock' in quick bursts of timeout.
replace dummy buffer with nullReader{} instead,
to avoid large memory allocations in memory
constrainted environments. allows running
obd tests in such environments.
Currently, listing directories on HDFS incurs a per-entry remote Stat() call
penalty, the cost of which can really blow up on directories with many
entries (+1,000) especially when considered in addition to peripheral
calls (such as validation) and the fact that minio is an intermediary to the
client (whereas other clients listed below can query HDFS directly).
Because listing directories this way is expensive, the Golang HDFS library
provides the [`Client.Open()`] function which creates a [`FileReader`] that is
able to batch multiple calls together through the [`Readdir()`] function.
This is substantially more efficient for very large directories.
In one case we were witnessing about +20 seconds to list a directory with 1,500
entries, admittedly large, but the Java hdfs ls utility as well as the HDFS
library sample ls utility were much faster.

If there are many listeners to bucket notifications or to the trace
subsystem, healing fails to work properly since it suspends itself when
the number of concurrent connections is above a certain threshold.
These connections are also continuous and not costly (*no disk access*),
it is okay to just ignore them in waitForLowHTTPReq().
this is to detect situations of corruption disk
format etc errors quickly and keep the disk online
in such scenarios for requests to fail appropriately.
String x might contain trimming spaces. And it needs to be trimmed. For
example, in csv files, there might be trimming spaces in a field that
ought to meet a query condition that contains the value without
trimming spaces. This applies to both intCast and floatCast functions.
Fixes two different types of problems
- continuation of the problem seen in FS #9992
as not fixed for erasure coded deployments,
reproduced this issue with spark and its fixed now
- another issue was leaking walk go-routines which
would lead to high memory usage and crash the system
this is simply because all the walks which were purged
at the top limit had leaking end walkers which would
consume memory endlessly.
closes#9966closes#10088
not all claims need to be present for
the JWT claim, let the policies not
exist and only apply which are present
when generating the credentials
once credentials are generated then
those policies should exist, otherwise
the request will fail.
- copyObject in-place decryption failed
due to incorrect verification of headers
- do not decode ETag when object is encrypted
with SSE-C, so that pre-conditions don't fail
prematurely.
This PR adds support for healing older
content i.e from 2yrs, 1yr. Also handles
other situations where our config was
not encrypted yet.
This PR also ensures that our Listing
is consistent and quorum friendly,
such that we don't list partial objects
In federated NAS gateway setups, multiple hosts in srvRecords
was picked at random which could mean that if one of the
host was down the request can indeed fail and if client
retries it would succeed. Instead allow server to figure
out the current online host quickly such that we can
exclude the host which is down.
At the max the attempt to look for a downed node is to
300 millisecond, if the node is taking longer to respond
than this value we simply ignore and move to the node,
total attempts are equal to number of srvRecords if no
server is online we simply fallback to last dialed host.
healing was not working properly when drives were
replaced, due to the error check in root disk
calculation this PR fixes this behavior
This PR also adds additional fix for missing
metadata entries from .minio.sys as part of
disk healing as well.
Added code to ignore and print more context
sensitive errors for better debugging.
This PR is continuation of fix in 7b14e9b660
Enforce bucket quotas when crawling has finished.
This ensures that we will not do quota enforcement on old data.
Additionally, delete less if we are closer to quota than we thought.
for users who don't have access to HDFS rootPath '/'

for which they have access to, allowing all writes to be
performed at `/path`.
NOTE: once configured in this manner you need to make
sure command line is correctly specified, otherwise
your data might not be visible
closes#10011
this PR to allow legacy support for big-data
applications which run older Java versions
which do not support the secure ciphers
currently defaulted in MinIO. This option
allows optionally to turn them off such
that client and server can negotiate the
best ciphers themselves.
This env is purposefully not documented,
meant as a last resort when client
application cannot be changed easily.
- admin info node offline check is now quicker
- admin info now doesn't duplicate the code
across doing the same checks for disks
- rely on StorageInfo to return appropriate errors
instead of calling locally.
- diskID checks now return proper errors when
disk not found v/s format.json missing.
- add more disk states for more clarity on the
underlying disk errors.
while we handle all situations for writes and reads
on older format, what we didn't cater for properly
yet was delete where we only ended up deleting
just `xl.meta` - instead we should allow all the
deletes to go through for older format without
versioning enabled buckets.
This commit fixes a dependency resolution problem w.r.t. minio => etcd.
Building any project depending on minio (e.g. mc) currently fails with
latest master since the module replace directive is not honored for
transitive / indirect dependencies.
This commit fixes this by adding the etcd module directly instead of
using a module replace instruction.
CORS is notorious requires specific headers to be
handled appropriately in request and response,
using cors package as part of handlerFunc() for
options method lacks the necessary control this
package needs to add headers.
Without instantiating a new rest client we can
have a recursive error which can lead to
healthcheck returning always offline, this can
prematurely take the servers offline.
gorilla/mux broke their recent release 1.7.4 which we
upgraded to, we need the current workaround to ensure
that our regex matches appropriately.
An upstream PR is sent, we should remove the
workaround once we have a new release.
- reduce locker timeout for early transaction lock
for more eagerness to timeout
- reduce leader lock timeout to range from 30sec to 1minute
- add additional log message during bootstrap phase
Main issue is that `t.pool[params]` should be `t.pool[oldest]`.
We add a bit more safety features for the code.
* Make writes to the endTimerCh non-blocking in all cases
so multiple releases cannot lock up.
* Double check expectations.
* Shift down deletes with copy instead of truncating slice.
* Actually delete the oldest if we are above total limit.
* Actually delete the oldest found and not the current.
* Unexport the mutex so nobody from the outside can meddle with it.
This commit adds a new admin API for creating master keys.
An admin client can send a POST request to:
```
/minio/admin/v3/kms/key/create?key-id=<keyID>
```
The name / ID of the new key is specified as request
query parameter `key-id=<ID>`.
Creating new master keys requires KES - it does not work with
the native Vault KMS (deprecated) nor with a static master key
(deprecated).
Further, this commit removes the `UpdateKey` method from the `KMS`
interface. This method is not needed and not used anymore.

etcd v3.5.0 will now have a properly imported versioned path
this fixes our pending migration to newer repo
Use a separate client for these calls that can take a long time.
Add request context to these so they are canceled when the client
disconnects instead except for ListObject which doesn't have any equivalent.
Healing an object which has multiple versions was not working because
the healing code forgot to consider errFileVersionNotFound error as a
use case that needs healing
Currently, lifecycle expiry is deleting all object versions which is not
correct, unless noncurrent versions field is specified.
Also, only delete the delete marker if it is the only version of the
given object.
- additionally upgrade to msgp@v1.1.2
- change StatModTime,StatSize fields as
simple Size/ModTime
- reduce 50000 entries per List batch to 10000
as client needs to wait too long to see the
first batch some times which is not desired
and it is worth we write the data as soon
as we have it.
object KMS is configured with auto-encryption,
there were issues when using docker registry -
this has been left unnoticed for a while.
This PR fixes an issue with compatibility.
Additionally also fix the continuation-token implementation
infinite loop issue which was missed as part of #9939
Also fix the heal token to be generated as a client
facing value instead of what is remembered by the
server, this allows for the server to be stateless
regarding the token's behavior.
When manual healing is triggered, one node in a cluster will
become the authority to heal. mc regularly sends new requests
to fetch the status of the ongoing healing process, but a load
balancer could land the healing request to a node that is not
doing the healing request.
This PR will redirect a request to the node based on the node
index found described as part of the client token. A similar
technique is also used to proxy ListObjectsV2 requests
by encoding this information in continuation-token
The S3 specification says that versions are ordered in the response of
list object versions.
mc snapshot needs this to know which version comes first especially when
two versions have the same exact last-modified field.
Readiness as no reasoning to be cluster scope
because that is not how the k8s networking works
for pods, all the pods to a deployment are not
sharing the network in a singleton. Instead they
are run as local scopes to themselves, with
readiness failures the pod is potentially taken
out of the network to be resolvable - this
affects the distributed setup in myriad of
different ways.
Instead readiness should behave like liveness
with local scope alone, and should be a dummy
implementation.
This PR all the startup times and overal k8s
startup time dramatically improves.
Added another handler called as `/minio/health/cluster`
to understand the cluster scope health.
Walk() functionality was missing on gateway
implementations leading to missing functionality
for the browser UI such as remove multiple objects,
download as zip file etc.
This PR brings a generic implementation across
all gateway's, it is not required to repeat the
same code in all gateway's
The default behavior is to cache each range requested
to cache drive. Add an environment variable
`MINIO_RANGE_CACHE` - when set to off, it disables
range caching and instead downloads entire object
in the background.
Fixes#9870
Bonus fix during versioning merge one of the PR was missing
the offline/online disk count fix from #9801 port it correctly
over to the master branch from release.
Additionally, add versionID support for MRF
Fixes#9910Fixes#9931
Users having endpoints with this format http://url:80 or http://url:443
will face signature mismatch error.
The reason is that S3 spec ignores :80 or :443 port in the endpoint
when calculating the signature, so this PR will just strip them.
This PR has the following changes
- Removing duplicate lookupConfigs() calls.
- Deprecate admin config APIs for NAS gateways. This will avoid repeated reloads of the config from the disk.
- WatchConfigNASDisk will be removed
- Migration guide for NAS gateways users to migrate to ENV settings.
NOTE: THIS PR HAS A BREAKING CHANGE

Looking into full disk errors on zoned setup. We don't take the
5% space requirement into account when selecting a zone.
The interesting part is that even considering this we don't
know the size of the object the user wants to upload when
they do multipart uploads.
It seems quite defensive to always upload multiparts to
the zone where there is the most space since all load will
be directed to a part of the cluster.
In these cases we make sure it can at least hold a 1GiB file
and we disadvantage fuller zones more by subtracting the
expected size before weighing.
- x-amz-storage-class specified CopyObject
should proceed regardless, its not a precondition
- sourceVersionID is specified CopyObject should
proceed regardless, its not a precondition
This PR fixes all the below scenarios
and handles them correctly.
- existing data/bucket is replaced with
new content, no versioning enabled old
structure vanishes.
- existing data/bucket - enable versioning
before uploading any data, once versioning
enabled upload new content, old content
is preserved.
- suspend versioning on the bucket again, now
upload content again the old content is purged
since that is the default "null" version.
Additionally sync data after xl.json -> xl.meta
rename(), to avoid any surprises if there is a
crash during this rename operation.
- Add changes to ensure remote disks are not
incorrectly taken online if their order has
changed or are incorrect disks.
- Bring changes to peer to detect disconnection
with separate Health handler, to avoid a
rather expensive call GetLocakDiskIDs()
- Follow up on the same changes for Lockers
as well
Just like GET/DELETE APIs it is possible to preserve
client supplied versionId's, of course the versionIds
have to be uuid, if an existing versionId is found
it is overwritten if no object locking policies
are found.
- PUT /bucketname/objectname?versionId=<id>
- POST /bucketname/objectname?uploads=&versionId=<id>
- PUT /bucketname/objectname?verisonId=<id> (with x-amz-copy-source)
Fixes potentially infinite allocations, especially in FS mode,
since lookups live up to 30 minutes. Limit walk pool sizes to 50
max parameter entries and 4 concurrent operations with the same
parameters.
Fixes#9835
PutObject on multiple-zone with versioning would not
overwrite the correct location of the object if the
object has delete marker, leading to duplicate objects
on two zones.
This PR fixes by adding affinity towards delete marker
when GetObjectInfo() returns error, use the zone index
which has the delete marker.
Bonus change to use channel to serialize triggers,
instead of using atomic variables. More efficient
mechanism for synchronization.

In the Current bug we were re-using the context
from previously granted lockers, this would
lead to lock timeouts for existing valid
read or write locks, leading to premature
timeout of locks.
This bug affects only local lockers in FS
or standalone erasure coded mode. This issue
is rather historical as well and was present
in lsync for some time but we were lucky to
not see it.
Similar changes are done in dsync as well
to keep the code more familiar
Fixes#9827
When updating all servers following the constructions of mc update,
only the endpoint server will be updated successfully.

- Implement a new xl.json 2.0.0 format to support,
this moves the entire marshaling logic to POSIX
layer, top layer always consumes a common FileInfo
construct which simplifies the metadata reads.
- Implement list object versions
- Migrate to siphash from crchash for new deployments
for object placements.
Fixes#2111
Historically due to lack of support for middlewares
we ended up writing wrapped handlers for all
middlewares on top of the gorilla/mux, this causes
multiple issues when we want to let's say
- Overload r.Body with some custom implementation
to track the incoming Reads()
- Add other sort of top level checks to avoid
DDOSing the server with large incoming HTTP
bodies.
Since 1.7.x release gorilla/mux provides proper
use of middlewares, which are honored by the muxer
directly. This makes sure that Go can honor its
own internal ServeHTTP(w, r) implementation where
Go net/http can wrap into its own customer readers.
This PR as a side-affect fixes rare issues of client
hangs which were reported in the wild but never really
understood or fixed in our codebase.

PR #9801 while it is correct, the loop isEndpointConnected()
was changed to rely on endpoint.String() which has the host
information as well, which is not correct value as input to
detect if the disk is down or up, if endpoint is local use
its local path value instead.
This commit changes the data key generation such that
if a MinIO server/nodes tries to generate a new DEK
but the particular master key does not exist - then
MinIO asks KES to create a new master key and then
requests the DEK again.
From now on, a SSE-S3 master key must not be created
explicitly via: `kes key create <key-name>`.
Instead, it is sufficient to just set the env. var.
```
export MINIO_KMS_KES_KEY_NAME=<key-name>
```
However, the MinIO identity (mTLS client certificate)
must have the permission to access the `/v1/key/create/`
API. Therefore, KES policy for MinIO must look similar to:
```
[
/v1/key/create/<key-name-pattern>
/v1/key/generate/<key-name-pattern>
/v1/key/decrypt/<key-name-pattern>
]
```
However, in our guides we already suggest that.
See e.g.: https://github.com/minio/kes/wiki/MinIO-Object-Storage#kes-server-setup
***
The ability to create master keys on request may also be
necessary / useful in case of SSE-KMS.
Current code was relying on globalEndpoints as
the source of secondary truth to obtain
the missing endpoints list when the disk
is offline, this is problematic
- there is no way to know if the getDisks()
returned endpoints total is same as the
ones list of globalEndpoints and it
belongs to a particular set.
- there is no order guarantee as getDisks()
is ordered as per format.json, globalEndpoints
may not be, so potentially end up including
incorrect endpoints.
To fix this bring getEndpoints() just like getDisks()
to ensure that consistently ordered endpoints are
always available for us to ensure that returned values
are consistent with what each erasure set would observe.
Uploading files with names that could not be written to disk
would result in "reduce your request" errors returned.
Instead check explicitly for disallowed characters and reject
files with `Object name contains unsupported characters.`
At a customer setup with lots of concurrent calls
it can be observed that in newRetryTimer there
were lots of tiny alloations which are not
relinquished upon retries, in this codepath
we were only interested in re-using the timer
and use it wisely for each locker.

Manual healing (as background healing) creates a heal task with a
possiblity to override healing options, such as deep or normal mode.
Use a pointer type in heal opts so nil would mean use the default

aws cli fails to set a bucket encryption configuration to MinIO server.
The reason is that aws cli does not send MD5-Content header. It seems
that MD5-Content is not required anymore.
This commit also returns Not Implemented header early to help mint tests
to ignore testing this API in gateway modes.
CopyObject was not correctly figuring out the correct
destination object location and would end up creating
duplicate objects on two different zones, reproduced
by doing encryption based key rotation.
Advantages avoids 100's of stats which are needed for each
upload operation in FS/NAS gateway mode when uploading a large
multipart object, dramatically increases performance for
multipart uploads by avoiding recursive calls.
For other gateway's simplifies the approach since
azure, gcs, hdfs gateway's don't capture any specific
metadata during upload which needs handler validation
for encryption/compression.
Erasure coding was already optimized, additionally
just avoids small allocations of large data structure.
Fixes#7206
GetDiskID() in storage rest client does not really issue a REST request
to the remote disk, but returns an in-memory value instead.
However, GetDiskID() should return an error when format.json is not
found or for other similar issues (unmounted disks, etc..)
GetDiskID() is only called when formatting disks and getting storage
informatio, hence this commit should not have a performance degradation.
Additionally also fix STS logs to filter out LDAP
password to be sent out in audit logs.

If the requested server is part of the set this will always read
from the local disk, even if the disk contains a parity shard.
In default setup there is a 50% chance that at least
one shard that otherwise would have been fetched remotely
will be read locally instead.
It basically trades RPC call overhead for reed-solomon.
On distributed localhost this seems to be fairly break-even,
with a very small gain in throughput and latency.

For easy management of this a generic helper has been added.
The documentation states that `nVolumeNameSize` and `nFileSystemNameSize` are:
> The length of a volume name buffer, in TCHARs. The maximum buffer size is MAX_PATH+1.
It seems like we allocated too little for them before, so expand it to 260 wchars.
some clients such as veeam expect the x-amz-meta to
be sent in lower cased form, while this does indeed
defeats the HTTP protocol contract it is harder to
change these applications, while these applications
get fixed appropriately in future.
x-amz-meta is usually sent in lowercased form
by AWS S3 and some applications like veeam
incorrectly end up relying on the case sensitivity
of the HTTP headers.
Bonus fixes
- Fix the iso8601 time format to keep it same as
AWS S3 response
- Increase maxObjectList to 50,000 and use
maxDeleteList as 10,000 whenever multi-object
deletes are needed.
No one really uses FS for large scale accounting
usage, neither we crawl in NAS gateway mode. It is
worthwhile to simply disable this feature as its
not useful for anyone.
Bonus disable bucket quota ops as well in, FS
and gateway mode
size calculation in crawler was using the real size
of the object instead of its actual size i.e either
a decrypted or uncompressed size.
this is needed to make sure all other accounting
such as bucket quota and mcs UI to display the
correct values.
This PR adds a new configuration parameter which allows readiness
check to respond within 10secs, this can be reduced to a lower value
if necessary using
```
mc admin config set api ready_deadline=5s
```
or
```
export MINIO_API_READY_DEADLINE=5s
```
net/http exposes ErrorLog but it is log.Logger
instance not an interface which can be overridden,
because of this reason the logging is interleaved
sometimes with TLS with messages like this on the
server
```
http: TLS handshake error from 139.178.70.188:63760: EOF
```
This is bit problematic for us as we need to have
consistent logging view for allow --json or --quiet
flags.
With this PR we ensure that this format is adhered to.
When running a zoned setup simply uploading will run
the system out of memory very fast.
Root cause: nFileSystemNameSize is a DWORD and
not a pointer. No idea how this didn't crash hard.
Furthermore replace poor mans utf16 -> string

This commit fixes a layout issue w.r.t. the KMS
Quickstart guide. The problem seems to be caused
by docs server not converting the markdown into html

This commit fixes this by converting the ordered list
into subsections.
Groups information shall be now stored as part of the
credential data structure, this is a more idiomatic
way to support large LDAP groups.
Avoids the complication of setups where LDAP groups
can be in the range of 150+ which may lead to excess

we shall save the group information on the server as
part of the credential data structure.
Bonus change support multiple mapped policies, across
all types of users.
This PR is a continuation from #9586, now the
entire parsing logic is fully merged into
bucket metadata sub-system, simplify the
quota API further by reducing the remove
quota handler implementation.
This commit simplifies the KMS configuration guide by
adding a get started section that uses our KES play instance
at `https://play.min.io:7373`.
Further, it removes sections that we don't recommend for production
anyways (MASTER_KEY).
Shuffling arguments that we pass to MinIO server are supported. However,
when that happens, Prometheus returns wrong information about disks usage
and online/offline status.
The commit fixes the issue by avoiding relying on xl.endpoints since
it is not ordered.
this is a major overhaul by migrating off all
bucket metadata related configs into a single
object '.metadata.bin' this allows us for faster
bootups across 1000's of buckets and as well
as keeps the code simple enough for future
work and additions.
Additionally also fixes#9396, #9394
To avoid this issue with refCounter refactor the code
such that
- locker() always increases refCount upon success
- unlocker() always decrements refCount upon success

are never granted two write lockers in any situation.
Thanks to @vcabbage for writing a nice reproducer.

There is a disparency of behavior under Linux & Windows about
the returned error when trying to rename a non existant path.
err := os.Rename("/path/does/not/exist", "/tmp/copy")
Linux:
isSysErrNotDir(err) = false
os.IsNotExist(err) = true
Windows:
isSysErrNotDir(err) = true
os.IsNotExist(err) = true
ENOTDIR in Linux is returned when the destination path
of the rename call contains a file in one of the middle
segments of the path (e.g. /tmp/file/dst, where /tmp/file
is an actual file not a directory)
However, as shown above, Windows has more scenarios when
it returns ENOTDIR. For example, when the source path contains
an inexistant directory in its path.
In that case, we want errFileNotFound returned and not
errFileAccessDenied, so this commit will add a further check to close
the disparency between Windows & Linux.
This commit updates the two client env. variables:
```
KES_CLIENT_TLS_KEY_FILE
KES_CLIENT_TLS_CERT_FILE
```
The KES CLI client expects the client key and certificate
as `KES_CLIENT_KEY` resp. `KES_CLIENT_CERT`.
The `ioutil.NopCloser(reader)` was hiding nested hash readers.
We make it an `io.Closer` so it can be attached without wrapping
and allows for nesting, by merging the requests.
test is failing in Azure gateway as a mapping from
x-amz-storage-class to Azure storage tier is failing
and there is no way to not send storage class in s3cmd.
The `keepHTTPResponseAlive` would cause errors to be
returned with status OK.
- Add '32' as a filler byte until a response is ready
- '0' to indicate the response is ready to be consumed
- '1' to indicate response has an error which needs
to be returned to the caller
Clear out 'file not found' errors from dir walker, since it may be
in a folder that has been deleted since it was scanned.
s3:HardwareInfo was removed recently. Users having that admin action
stored in the backend will have an issue starting the server.
To fix this, we need to avoid returning an error in Marshal/Unmarshal
when they encounter an invalid action and validate only in specific
location.
Currently the validation is done and in ParseConfig().
This PR is to ensure that we call the relevant object
layer APIs for necessary S3 API level functionalities
allowing gateway implementations to return proper
errors as NotImplemented{}
This allows for all our tests in mint to behave
appropriately and can be handled appropriately as
well.
S3 is now natively supported by B2 cloud storage provider
there is no reason to use specialized gateway for B2 anymore,
our current S3 gateway with caching would work with B2.
Resolves#8584
requests in federated setups for STS type calls which are
performed at '/' resource should be routed by the muxer,
the assumption is simply such that requests without a bucket
in a federated setup cannot be proxied, so serve them at
current server.
This commit makes the KES client use HTTP/2
when establishing a connection to the KES server.
This is necessary since the next KES server release
will require HTTP/2.
We should allow quorum errors to be send upwards
such that caller can retry while reading bucket
encryption/policy configs when server is starting
up, this allows distributed setups to load the
configuration properly.
Current code didn't facilitate this and would have
never loaded the actual configs during rolling,
server restarts.
This commit updates the KMS guide to reflect the
latest changes in KES. Based on internal design
meetings we made some adjustments to the overall
KES configuration.
This commit ensures that the KMS guide contains
a working KES demo-setup with Vault.
In large setups this avoids unnecessary data transfer
across nodes and potential locks.
This PR also optimizes heal result channel, which should
be avoided for each queueHealTask as its expensive
to create/close channels for large number of objects.
This PR allows setting a "hard" or "fifo" quota
restriction at the bucket level. Buckets that
have reached the FIFO quota configured, will
automatically be cleaned up in FIFO manner until
bucket usage drops to configured quota.
If a bucket is configured with a "hard" quota
ceiling, all further writes are disallowed.
ResponseWriter & RecordAPIStats has similar role, merge them.
This commit will also fix wrong auditing for STS and Web and others
since they are using ResponseWriter instead of the RecordAPIStats.
A user can incorrectly mounts a newly fresh disk. MinIO will detect
that it is writing with a rootfs disk and will mark it down. However,
it is hard for the user to understand what's going on.
This commit will just print a notice so it will be easy to spot
such use case.
- elasticsearch client should rely on the SDK helpers
instead of pure HTTP calls.
- webhook shouldn't need to check for IsActive() for

symmetric value automatically.
Fixes#9416
By monitoring PUT/DELETE and heal operations it is possible
to track changed paths and keep a bloom filter for this data.
This can help prioritize paths to scan. The bloom filter can identify
paths that have not changed, and the few collisions will only result
in a marginal extra workload. This can be implemented on either a
bucket+(1 prefix level) with reasonable performance.
The bloom filter is set to have a false positive rate at 1% at 1M
entries. A bloom table of this size is about ~2500 bytes when serialized.
To not force a full scan of all paths that have changed cycle bloom
filters would need to be kept, so we guarantee that dirty paths have
been scanned within cycle runs. Until cycle bloom filters have been
collected all paths are considered dirty.
this commit avoids lots of tiny allocations, repeated
channel creates which are performed when filtering
the incoming events, unescaping a key just for matching.
also remove deprecated code which is not needed
anymore, avoids unexpected data structure transformations
from the map to slice.
we have policy available for sub-admin users to set/get/delete

re-implement the cache purging routine to
avoid using ioutil.ReadDir which can lead
to high allocations when there are cache
directories with lots of content, or
when cache is installed in memory constrainted

Instead rely on a callback function where we
are not using memory no-more than 8KiB per
cycle.

- keep long running obd network tests alive
- fix error - wrong number of parents in process OBD info
- ensure that osinfo does not error out when inside containers

The generic client transport uses a default limit of 64 conns per transport.
This could end up limiting and throttling usage, and artificially slowing
down the performance of MinIO even on hardware capable of doing better.
New value defaults to 100K events by default,
but users can tune this value upto any value
they seem necessary.

This PR fixes couple of behaviors with service accounts
- not need to have session token for service accounts
- service accounts can be generated by any user for themselves
implicitly, with a valid signature.
- policy input for AddNewServiceAccount API is not fully typed
allowing for validation before it is sent to the server.
- also bring in additional context for admin API errors if any
when replying back to client.
- deprecate GetServiceAccount API as we do not need to reply
back session tokens
- Introduced a function `FetchRegisteredTargets` which will return
a complete set of registered targets irrespective to their states,
if the `returnOnTargetError` flag is set to `False`
- Refactor NewTarget functions to return non-nil targets
- Refactor GetARNList() to return a complete list of configured targets
Picking up all support files from the builder image has the advantage
that the Dockerfile is now fully selfcontained and can be also
run just standalone.
This allows also cross-compilation and pushing with the proper manifests
with Docker Buildkit:
```
docker buildx create --name xbuilder
docker buildx use xbuilder
docker buildx build -f Dockerfile.minio --platform linux/arm/v7,linux/amd64 --progress plain --push -t minio/minio .
```
which also has the advantage that the Dockerfile is the same
for all platforms.

This commit fixes a performance issue caused
by too many calls to the external KMS - i.e.
for single-part PUT requests.
In general, the issue is caused by a sub-optimal
code structure. In particular, when the server
encrypts an object it requests a new data encryption
key from the KMS. With this key it does some key
derivation and encrypts the object content and
ETag.
However, to behave S3-compatible the MinIO server
has to return the plaintext ETag to the client
in case SSE-S3.
Therefore, the server code used to decrypt the
(previously encrypted) ETag again by requesting
the data encryption key (KMS decrypt API) from
the KMS.
This leads to 2 KMS API calls (1 generate key and
1 decrypt key) per PUT operation - while only
one KMS call is necessary.
This commit fixes this by fetching a data key only
once from the KMS and keeping the derived object
encryption key around (for the lifetime of the request).
This leads to a significant performance improvement
w.r.t. to PUT workloads:
```
Operation: PUT
Operations: 161 -> 239
Duration: 28s -> 29s
* Average: +47.56% (+25.8 MiB/s) throughput, +47.56% (+2.6) obj/s
* Fastest: +55.49% (+34.5 MiB/s) throughput, +55.49% (+3.5) obj/s
* 50% Median: +58.24% (+32.8 MiB/s) throughput, +58.24% (+3.3) obj/s
* Slowest: +1.83% (+0.6 MiB/s) throughput, +1.83% (+0.1) obj/s
```

In addition to the above, if the user is mapped to a policy or

make rest of the Walk() function more predictable,
it was observed that in nominal deployments even
without much workload the drives are generally

it is good for all other I/O, it may simply slow
down Listing immensely which is not useful.

In FS mode under Windows, removing an object will not automatically.
remove parent empty prefixes.
The reason is that path.Dir() was used, however filepath.Dir() is
more appropriate since filepath is physical (meaning it operates
on OS filesystem paths)
This is not caught because failure for Windows CI is not caught.
fs-v1 in server mode only checks to see if the path exist, so that it

NAS gateway creates non-multipart-uploads with mode 0666.
But multipart-uploads are created with a differing mode of 0644.
Both modes should be equal! Else it leads to files with different
permissions based on its file-size. This patch solves that by
using 0666 for both cases.
This is to improve responsiveness for all
admin API operations and allowing callers
to cancel any on-going admin operations,
if they happen to be waiting too long.

As an optimization of the healing, HealObjects() avoid sending an
object to the background healing subsystem when the object is
present in all disks.
However, HealObjects() should have checked the scan type, if this
deep, always pass the object to the healing subsystem.
Currently, a tree walking, needed to a list objects in a specific
set quits listing as long as it finds no entries in a disk, which
is wrong.
This affected background healing, because the latter is using
tree walk directly. If one object does not exist in the first
disk for example, it will be seemed like the object does not
exist at all and no healing work is needed.
This commit fixes the behavior.
The staleness of a lock should be determined by
the quorum number of entries returning stale,
this allows for situations when locks are held
when nodes are down - we don't accidentally
clear locks unintentionally when they are valid
and correct.
Also lock maintenance should be run by all servers,
not one server, stale locks need to be run outside
the requirement for holding distributed locks.

This commit fixes the env. variable in the
KMS guide used to specify the CA certificates
for the KES server.
Before the env. variable `MINIO_KMS_KES_CAPATH` has
been used - which works in non-containerized environments
due to how MinIO merges the config file and environment
variables. In containerized environments (e.g. docker)
this does not work and trying to specify `MINIO_KMS_KES_CAPATH`
instead of `MINIO_KMS_KES_CA_PATH` eventually leads to MinIO not
trusting the certificate presented by the kes server.
See: cfd12914e1/cmd/crypto/config.go (L186)

This translation was broken, fix it.
Bulk delete API was using cleanupObjectsBulk() which calls posix
listing and delete API to remove objects internal files in the
backend (xl.json and parts) one by one.
Add DeletePrefixes in the storage API to remove the content
of a directory in a single call.
Also use a remove goroutine for each disk to accelerate removal.
Currently the code assumed some orthogonal requirements
which led situations where when we have a setup where
we have let's say for example 168 drives, the final
set_drive_count chosen was 14. Indeed 168 drives are
divisible by 12 but this wasn't allowed due to an
unexpected requirement to have 12 to be a perfect modulo
of 14 which is not possible. This assumption was incorrect.
This PR fixes this old assumption properly, also adds
few tests and some negative tests as well. Improvements
are seen in error messages as well.
- Remove the requirement to honor storage class for deletes
- Improve `posix.DeleteFileBulk` code to Stat the volumeDir
only once per call, rather than for all object paths.
Recent modification in the code led to incorrect calculation
of offline disks.
This commit saves the endpoint list in a xlObjects then we know
the name of each disk.
lock ownership is limited to endpoints on first zone,
as we do not hold locks on other zones in an expanded
setup. current code unintentionally expired active locks
when it couldn't see ownership from the secondary zone
which leads to unexpected bugs as locking fails to work
as expected.

Metrics used to have its own code to calculate offline disks.
StorageInfo() was avoided because it is an expensive operation
by sending calls to all nodes.
To make metrics & server info share the same code, a new
argument `local` is added to StorageInfo() so it will only
query local disks when needed.
Metrics now calls StorageInfo() as server info handler does
but with the local flag set to false.

Add dummy calls which respond success when ACL's

to fully implement the functionality just that
we can respond with success for default ACLs
Avoid GetObjectNInfo call from cache in CopyObjectHandler
- in the case of server side copy with metadata replacement,
the reader returned from cache is never consumed, but the net
effect of GetObjectNInfo from cache layer, is cache holding a
write lock to fill the cache. Subsequent stat operation on cache in
CopyObject is not able to acquire a read lock, thus causing the hang.

we don't need to validateFormats again once we have obtained
reference format, because it is possible that at this stage
another server is doing a disk heal during startup, once
in a while due to delays we get false positives and our
server doesn't start.
Format in quorum as reference format can be assumed as valid
and we proceed further, until and unless HealFormat re-inits
the disks after a successful heal.
Also use separate port for healing tests to avoid any
conflicts with regular build testing.

RegisterNotificationTargets() cleans up all connections

change maxActiveIOCount to 3, meaning it will pause

Remove the random sleep. This is running in 4 goroutines,
so mostly doing nothing.
We use the getSize latency to estimate system load,
meaning when there is little load on the system and
we get the result fast we sleep a little.
If it took a long time we have high load and release
ourselves longer.
We are sleeping inside the mutex so this affects all
goroutines doing IO.

This is to fix a situation where an object name incorrectly

This commit fixes typos in the displayed server info
w.r.t. the KMS and removes the update status.
For more information about why the update status
is removed see: PR #8943
This commit removes the `Update` functionality
from the admin API. While this is technically
a breaking change I think this will not cause
any harm because:
- The KMS admin API is not complete, yet.
At the moment only the status can be fetched.
- The `mc` integration hasn't been merged yet.
So no `mc` client could have used this API
in the past.
The `Update`/`Rewrap` status is not useful anymore.
It provided a way to migrate from one master key version
to another. However, KES does not support the concept of
key versions. Instead, key migration should be implemented
as migration from one master key to another.
Basically, the `Update` functionality has been implemented just
for Vault.

XL crawling wrongly returns a zero buckets count when
there are no objects uploaded in the server yet. The reason is
data of the crawler of posix returns invalid result when all
disks has zero objects.
A simple fix is to always pick the crawling result of the first
disk but choose over the result of the disk which has the most
objects in it.
looks like 1024 buffer size is not enough in
all situations, use 8192 instead which
can satisfy all the rare situations that
may arise in base64 decoding.
multi-delete API failed with write quorum errors
under following situations
- list of files requested for delete doesn't exist
anymore can lead to quorum errors and failure
- due to usage of query param for paths, for really

malformed as unexpected.
This was reproduced with warp

Choosing maxAllowedIOError is arbitrary and
prone to errors, when drives might be perfectly
capable of taking I/O with only few locations
return I/O error. This is a hindrance of sort
where backend filesystems like ZFS can automatically
fix and handle these scenarios.
The added problem with current approach that we
take the drive offline, making it virtually impossible
to bring it online without restart the server which
is not desirable on a busy cluster. Remove this state
such that let the backend return error appropriately
to caller and let the caller decide what to do with
the error.
return http.ErrServerClosed with proper body when
server is shutting down, allowing more context instead

code of this form is always racy, when the
map itself is being written to as well
```
func (r Map) retMap() map[string]string {

return r.internalMap
}
func (r Map) addMap(k, v string) {
.. lock ..
r.internalMap[k] = v
}

Anyone reading from `retMap()` is not protected
because of locking and we need to make sure
to avoid code in this manner. Always safe to
copy the map and return.
Zone abstraction of object layer was returning `nil`

However using MakeVolBulk() is not appropriate in the
case of a user migrating from a version which does not

MakeVolBulk() exits early when an error is occured:
errVolumeExists in this case, which is expected since
some directories such as tmp/ already exist.
This commit will avoid use MakeVolBulk and use MakeVol
instead.
Also the PR will make each node creates meta volumes
in its local disks and stop relying on the first disk

Currently when connections to vault fail, client

Re-purpose *crypto.Error* type to send appropriate
errors back to the client.
In existing functionality we simply return a generic
error such as "MalformedPolicy" which indicates just
a generic string "invalid resource" which is not very
meaningful when there might be multiple types of errors
during policy parsing. This PR ensures that we send
these errors back to client to indicate the actual
error, brings in two concrete types such as
- iampolicy.Error
- policy.Error

If two distinct clusters are started with different domains
along with single common domain, this situation was leading
to conflicting buckets getting created on different clusters

with one common domain, but each cluster may have their own
domains.

This is to ensure that when we have multiple tenants
deployed all sharing the same etcd for global bucket
should avoid listing each others buckets, this leads
to information leak which should be avoided unless
etcd is not namespaced for IAM assets in which case
it can be assumed that its a federated setup.
Federated setup and namespaced IAM assets on etcd
is not supported since namespacing is only useful
when you wish to separate the tenants as isolated
instances of MinIO.
This PR allows a new type of behavior, primarily
driven by the usecase of m3(mkube) multi-tenant
deployments with global bucket support.
Currently all bucket events are sent to all watchers

- .minio.sys is updated to indicate if backend is encrypted
or not.
The approach is that now safe mode is only invoked when
we cannot read the config or under some catastrophic
situations, but not under situations when config entries
are invalid or unreachable. This allows for maximum
availability for MinIO and not fail on our users unlike
most of our historical releases.
This commit adds support for the minio/kes KMS.
See: https://github.com/minio/kes
In particular you can configure it as KMS by:
- `export MINIO_KMS_KES_ENDPOINT=` // Server URL
- `export MINIO_KMS_KES_KEY_FILE=` // TLS client private key
- `export MINIO_KMS_KES_CERT_FILE=` // TLS client certificate
- `export MINIO_KMS_KES_CA_PATH=` // Root CAs issuing server cert
- `export MINIO_KMS_KES_KEY_NAME=` // The name of the (default)
master key
Admin data usage info API returns the following
(Only FS & XL, for now)
- Number of buckets
- Number of objects
- The total size of objects
- Objects histogram
- Bucket sizes
In replica sets, hosts resolve to localhost
IP automatically until the deployment fully
comes up. To avoid this issue we need to
wait for such resolution.

- old mc is used against new minio release which is incompatible
returns an appropriate for client action.
- any older servers talking to each other, report appropriate error
- incompatible peer servers should report error and reject the calls

This is to avoid making calls to backend and requiring
gateways to allow permissions for ListBuckets() operation
just for Liveness checks, we can avoid this and make
our liveness checks to be more performant.

On Kubernetes/Docker setups DNS resolves inappropriately
sometimes where there are situations same endpoints with
multiple disks come online indicating either one of them
is local and some of them are not local. This situation
can never happen and its only a possibility in orchestrated
deployments with dynamic DNS. Following code ensures that we
treat if one of the endpoint says its local for a given host
it is true for all endpoints for the same host. Following code
ensures that this assumption is true and it works in all
scenarios and it is safe to assume for a given host.
This PR also adds validation such that we do not crash the
server if there are bugs in the endpoints list in dsync
initialization.

Minio V2 listing uses object names/prefixes as continuation tokens. This
is problematic when object names contain some characters that are forbidden
in XML documents. This PR will use base64 encoded form of continuation

errors.errorString() cannot be marshalled by gob
encoder, so using a slice of []error would fail
to be encoded. This leads to no errors being
generated instead gob.Decoder on the storage-client

handling such translations and register this type
for gob encoding support.

Updates #7475
The Java implementation has a 128KB buffer and a message must be emitted before that is used. #7475 therefore limits the message size to 128KB. But up to 256 bytes are written to the buffer in each call. This means we must emit a message before shorter than 128KB.
Therefore we change the limit to 128KB minus 256 bytes.

Add LDAP based users-groups system
This change adds support to integrate an LDAP server for user
authentication. This works via a custom STS API for LDAP. Each user
accessing the MinIO who can be authenticated via LDAP receives
temporary credentials to access the MinIO server.
LDAP is enabled only over TLS.
User groups are also supported via LDAP. The administrator may
configure an LDAP search query to find the group attribute of a user -
this may correspond to any attribute in the LDAP tree (that the user
has access to view). One or more groups may be returned by such a
query.
A group is mapped to an IAM policy in the usual way, and the server
enforces a policy corresponding to all the groups and the user's own
mapped policy.
When LDAP is configured, the internal MinIO users system is disabled.
It looks like from implementation point of view fastjson
parser pool doesn't behave the same way as expected
when dealing many `xl.json` from multiple disks.
The fastjson parser pool usage ends up returning incorrect

to older entries. This led to the subtle bug where checksum
info is duplicated from a previous xl.json read of a different
file from different disk.
With this PR, liveness check responds with 200 OK with "server-not-

This PR also updates sample Swarm yaml files to use correct values
for healthcheck fields.

This commit adds an admin API route and handler for
requesting status information about a KMS key.
Therefore, the client specifies the KMS key ID (when
empty / not set the server takes the currently configured
default key-ID) and the server tries to perform a dummy encryption,
re-wrap and decryption operation. If all three succeed we know that
the server can access the KMS and has permissions to generate, re-wrap
and decrypt data keys (policy is set correctly).
This is a defensive change to avoid any future issues,
from this part of the code. New change also ensures
to populate UUID if present for the right disk.
This commit fixes the web ZIP download handler for

A possible fix for #8071
There are multiple possibilities for running MinIO within
a container e.g. configurable address, non-root user etc.
This makes it difficult to identify actual IP / Port to
use to check healthcheck status from within a container.
It is simpler to use external healthcheck mechanisms
like healthcheck command in docker-compose to check
for MinIO health status. This is similar to how checks
work in Kubernetes as well.
This PR removes the healthcheck script used inside
Docker container and ad documentation on how to
use docker-compose based healthcheck mechanism.

When a peer client which higher version sends a request to a peer
server with lower version, the returned status code is 200 OK instead
of 405 code. The reason is that the peer client request reaches the
browser handler, which registers itself by '/minio' route but without
any other constraints. Adding filtering by user agent header to the
browser route so internal requests to old endpoints versions return
405 error code.
This is a behavior change from AWS S3, but it is done with
better judgment on our end to allow the listing of buckets only
which user has access to.
The advantage is this declutters the UI for users and only
lists bucket which they have access to.
Precursor for this feature to be applicable is a policy
must have the following actions
```
s3:ListAllMyBuckets
```
and
```
s3:ListBucket
```
enabled in the policy.

When checking if federation is necessary, the code compares
the SRV record stored in etcd against the list of endpoints
that the MinIO server is exposing. If there is an intersection
in this list the request is forwarded.
The SRV record includes both the host and the port, but the
intersection check previously only looked at the IP address. This
would prevent federation from working in situations where the endpoint
IP is the same for multiple MinIO servers. Some examples of where this
can occur are:
- running mulitiple copies of MinIO on the same host
- using multiple MinIO servers behind a NAT with port-forwarding
Since MinIO by default is not fully S3 compatible, this fact should be
specified in a prominent place in the quick start guide so people
new to MinIO don't have to spend hours figuring it out the hard way.
This commit adds a new method `UpdateKey` to the KMS
interface.
The purpose of `UpdateKey` is to re-wrap an encrypted
data key (the key generated & encrypted with a master key by e.g.
Vault).
For example, consider Vault with a master key ID: `master-key-1`
and an encrypted data key `E(dk)` for a particular object. The
data key `dk` has been generated randomly when the object was created.
Now, the KMS operator may "rotate" the master key `master-key-1`.
However, the KMS cannot forget the "old" value of that master key
since there is still an object that requires `dk`, and therefore,
the `D(E(dk))`.
With the `UpdateKey` method call MinIO can ask the KMS to decrypt
`E(dk)` with the old key (internally) and re-encrypted `dk` with
the new master key value: `E'(dk)`.
However, this operation only works for the same master key ID.
When rotating the data key (replacing it with a new one) then
we perform a `UnsealKey` operation with the 1st master key ID
and then a `GenerateKey` operation with the 2nd master key ID.
This commit also updates the KMS documentation and removes
the `encrypt` policy entry (we don't use `encrypt`) and
add a policy entry for `rewarp`.
After some extensive refactors, it turned out empty directories
are not healed and heal status is also not reported correctly.
This commit fixes it and adds the appropriate unit tests
This PR fixes relying on r.Context().Done()

This is also a refactor which is already done
in the new config migration change. Attempt
to avoid any network I/O during Unmarshal of
JSON from disk, instead do it later when
updating the in-memory data structure.
In situations such as when client uploading data,
prematurely disconnects from server such as pressing
ctrl-c before uploading all the data. Under this
situation in distributed setup we prematurely
disconnect disks causing a reconnect loop. This has
an adverse affect we end up leaving a lot of files
in temporary location which ideally should have been
cleaned up when Put() prematurely fails.
This is also a regression which got introduced in #7610

- User identity file is now versioned.
- Migrate old data to the new format.
Calling ListMultipartUploads fails if an upload is aborted while a
part is being uploaded because the directory for the upload exists
(since fsRenameFile ends up calling os.MkdirAll) but the meta JSON file
doesn't. To fix this we make sure an upload hasn't been aborted during
PutObjectPart by checking the existence of the directory for the upload
while moving the temporary part file into it.

This PR fixes a security issue where an IAM user based
on his policy is granted more privileges than restricted
by the users IAM policy.
This is due to an issue of prefix based Matcher() function
which was incorrectly matching prefix based on resource
prefixes instead of exact match.
Previously the read/write lock applied both for gateway use cases as
well the object store use case. Nothing from sys is touched or looked
at in the gateway usecase though, so we don't need to lock. Don't lock
to make the gateway policy getting a little more efficient, particularly
as where this is called from (checkRequestAuthType) is quite common.
etcd when used in federated setups, currently
mandates that all clusters should have same
config.json, which is too restrictive and makes
federation a restrictive environment.
This change makes it apparent that each cluster
needs to be independently managed if necessary
from `mc admin info` command line.
Each cluster with in federation can have their
own root credentials and as well as separate
regions. This way buckets get further restrictions
and allows for root creds to be not common
across clusters/data centers.
Existing data in etcd gets migrated to backend
on each clusters, upon start. Once done
users can change their config entries
independently.
This allows MinIO containers to run properly without
expecting higher privileges in situations where following
restrictions on containers are used
- docker run --user uid:gid
- docker-compose up (with docker-compose.yml with user)

command: minio server /data

This patch includes the following changes in event store interface
- Removes memory store. We will not persist events in memory anymore, if `queueDir` is not set.
- Orders the events before replaying to the broker.
The problem in current code was we were removing
an entry from a lock lockerMap without considering
the fact that different entry for same resource is
a possibility due the nature of locks that can be
acquired in parallel before we decide if the lock
is considered stale
A sequence of events is as follows
- Lock("resource")
- lockMaintenance(finds a long lived lock in this "resource")
- Owner node rebooted which now retruns Expired() as true for
this "resource"
- Unlock("resource") which succeeded in quorum
- Now by this time application retried and acquired a new
Lock() on the same "resource"
- Now that we have Expired() true from the previous call,
we proceed to purge the entry from the local lockMap()
local lockMap reports a different entry for the expired
UID which results in a spurious log entry.
This PR removes this logging as this situation is an
expected scenario.

and that seems to cause problems.
Currently we used to reload users every five minutes,
regardless of etcd is configured or not. But with etcd
configured we can do this more asynchronously to trigger
a refresh by using the watch API

One user has seen this following error log:

2: cmd/xl-v1-metadata.go:501:cmd.writeUniqueXLMetadata.func1()
This can happen when CompleteMultipartUpload fails with write quorum,
the S3 client will retry (since write quorum is 500 http response),
however the second call of CompleteMultipartUpload will fail because
this latter doesn't truly use a random uuid under .minio.sys/tmp/
directory but pick the upload id.
This commit fixes the behavior to choose a random uuid for generating
xl.json
Since AssumeRole API was introduced we have a wrong route
match which results in certain clients failing to upload objects
using multipart because, multipart POST conflicts with STS POST
AssumeRole API.
Write a proper matcher function which verifies the route more
appropriately such that both can co-exist.
Other listing optimizations include
- remove double sorting while filtering object entries
- improve error message when upload-id is not in quorum
- use jsoniter for full unmarshal json, instead of gjson
- remove unused code
Allow server to start if one of the local nodes in docker/kubernetes setup is successfully resolved
- The rule is that we need atleast one local node to work. We dont need to resolve the
rest at that point.
- In a non-orchestrational setup, we fail if we do not have atleast one local node up
and running.
- In an orchestrational setup (docker-swarm and kubernetes), We retry with a sleep of 5
seconds until any one local node shows up.

When the first login attempt is failed(due to incorrect secretkey)
and the next attempt is successful. Error message shown for
the previous attempts should go away.
Fixes#7514
In distributed mode, use REST API to acquire and manage locks instead
of RPC.
RPC has been completely removed from MinIO source.
Since we are moving from RPC to REST, we cannot use rolling upgrades as the
nodes that have not yet been upgraded cannot talk to the ones that have
been upgraded.
We expect all minio processes on all nodes to be stopped and then the
upgrade process to be completed.
Also force http1.1 for inter-node communication
common prefixes in bucket name if already created
are disallowed when etcd is configured due to the
prefix matching issue. Make sure that when we look
for bucket we are only interested in exact bucket
name not the prefix.
- [x] Support bucket and regular object operations
- [x] Supports Select API on HDFS
- [x] Implement multipart API support
- [x] Completion of ListObjects support
As a part of #7302, MinIO server's (configured with https) response when it
encounters http request has changed from 403 to 400 and the custom message
"SSL Required" is removed.
Accordingly healthcheck script is updated to check for status 400 before
trying https request.
Fixes#7517
Currently, the backend minio server uses the same data directory
as the mint test itself, causing `s3 sync` to fail often.
Now `minio` backend will use a different data directory `/data`
instead of `/mint/data`
There is no written specification about how to encode key names
when url encoding type is passed.
However, this change will encode URLs as url.QueryEscape() does
while considering AWS S3 exceptions.
This commit adds a unit test for the vault
config verification (which covers also `IsEmpty()`).
Vault-related code is hard to test with unit tests
since a Vault service would be necessary. Therefore
this commit only adds tests for a fraction of the code.
Fixes#7409
Most hadoop distributions hortonworks, cloudera all
depend on aws-sdk-java 1.7.x to 1.10.x - the releases
which have bugs related case sensitive check for
ETag header. Go changes the case of the headers set
to be canonical but only preserves them when set
through a direct map.
This fixes most compatibility issues we have had
in the past supporting older hadoop distributions.
This commit fixes a privilege escalation issue against
the S3 and web handlers. An authenticated IAM user
can:
- Read from or write to the internal '.minio.sys'
bucket by simply sending a properly signed
S3 GET or PUT request. Further, the user can
- Read from or write to the internal '.minio.sys'
bucket using the 'Upload'/'Download'/'DownloadZIP'
API by sending a "browser" request authenticated
with its JWT token.
This commit fixes another privilege escalation issue
abusing the inter-node communication of distributed
servers to obtain/modify the server configuration.
The inter-node communication is authenticated using
JWT-Tokens. Further, IAM users accessing the cluster
via the web UI also get a JWT token and the browser
will add this "user" JWT token to each the request.
Now, a user can extract that JWT token an can craft
HTTP POST requests for the inter-node communication
API endpoint. Since the server accepts ANY valid
JWT token it also accepts inter-node commands from
an authenticated user such that the user can execute
arbitrary commands bypassing the IAM policy engine
and impersonate other users, change its own IAM policy
or extract the admin access/secret key.
This is fixed by only accepting "admin" JWT tokens
(tokens containing the admin access key - and therefore
were generated with the admin secret key). Consequently,
only the admin user can execute such inter-node commands.
Simplify the cmd/http package overall by removing
custom plain text v/s tls connection detection, by
migrating to go1.12 and choose minimum version
to be go1.12
Also remove all the vendored deps, since they
are not useful anymore.
A race is detected between a bytes.Buffer generated with cmd/rpc.Pool
and http2 module. An issue is raised in golang (https://github.com/golang/go/issues/31192).
Meanwhile, this commit disables Pool in RPC code and it generates a
new 1kb of bytes.Buffer for each RPC call.
Before this commit, nodes wait indefinitely without showing any
indicate error message when a node is started with different access
and secret keys.
This PR will show '401 Unauthorized' in this case.
Currently message is set to error type value.
Message field is not used in error logs. it is used only in the case of info logs.
This PR sets error message field to store error type correctly.
Copying an encrypted SSEC object when this latter is uploaded using
multipart mechanism was failing because ETag in case of encrypted
multipart upload is not encrypted.
This PR fixes the behavior.
This fixes varying pids for server-respawns. And avoids duplicate process
creating multiple pids when the server restart signal is triggered with
service restart enabled.
Fixes#7350
It is required to set the environment variable in the case of distributed
minio. LoadCredentials is used to notify peers of the change and will not work if
environment variable is set. so, this function will never be called.
In scenario 1
```
- bucket/object-prefix
- bucket/object-prefix/object
```
Server responds with `XMinioParentIsObject`
In scenario 2
```
- bucket/object-prefix/object
- bucket/object-prefix
```
Server responds with `XMinioObjectExistsAsDirectory`
Fixes#6566
Healing scan used to read all objects parts to check for bitrot
checksum. This commit will add a quicker way of healing scan
by only checking if parts are actually present in disks or not.
We should internally handle when http2 input stream has smaller
content than its content-length header
Upstream issue reported https://github.com/golang/go/issues/30648
This a change which we need to handle internally until Go fixes it
correctly, till now our code doesn't expect a custom error to be returned.
- Also, switch to jstream to generate internal record representation
from CSV/JSON readers
- This fixes a bug in which JSON output objects have their keys
reversed from the order they are specified in the Select columns.
- Also includes a fix for tests.
CopyObject precondition checks into GetObjectReader
in order to perform SSE-C pre-condition checks using the
last 32 bytes of encrypted ETag rather than the decrypted
ETag
This also necessitates moving precondition checks for
gateways to gateway layer rather than object handler check
if a bucket with `Captialized letters` is created, `InvalidBucketName` error
will be returned.
In the case of pre-existing buckets, it will be listed.
Fixes#6938
Prevents deferred close functions from being called while still
attempting to copy reader to snappyWriter.
Reduces code duplication when compressing objects.
This change allows indefinitely running go-routines to cleanup
gracefully.
This channel is now closed at the beginning of each test so that
long-running go-routines quit and a new one is assigned.
The side affect of this change memory
increase, but this is a trade-off between
performance and actual memory usage.
For all practical scenarios this should be
an adequate change.
Currently windows support was relying on Symlink as
a way to detect a drive, this doesn't work in latest
Windows 2016, fix this to use a proper mechanism by
using win32 APIs.
Additionally also add support for detecting bind mounts
on Linux.
- The events will be persisted in queueStore if `queueDir` is set.
- Else, if queueDir is not set events persist in memory.
The events are replayed back when the mqtt broker is back online.
Clients like AWS SDK Java and AWS cli XML parsers are
unable to handle on `\r\n` characters to avoid these
errors send XML header first and write white space characters
instead.
Also handle cases to avoid double WriteHeader calls
- Current implementation was spawning renewer goroutines
without waiting for the lease duration to end. Remove vault renewer
and call vault.RenewToken directly and manage reauthentication if
lease expired.
Go script makes it easy to read/maintain. Also updated the timeout
in Dockerfiles from 5s to default 30s and test interval to 1m
Higher timeout makes sense as server may sometimes respond slowly
if under high load as reported in #6974Fixes#6974
We should change the logic for both isObject()
and isObjectDir() leaf detection to be done
with quorum, due to how our directory navigation
works - this allows for properly deleting all
the dangling directories or objects if any.
This commit fixes a nil pointer dereference issue
that can occur when the Vault KMS returns e.g. a 404
with an empty HTTP response. The Vault client SDK
does not treat that as error and returns nil for
the error and the secret.
Further it simplifies the token renewal and
re-authentication mechanism by using a single
background go-routine.
The control-flow of Vault authentications looks
like this:
1. `authenticate()`: Initial login and start of background job
2. Background job starts a `vault.Renewer` to renew the token
3. a) If this succeeds the token gets updated
b) If this fails the background job tries to login again
4. If the login in 3b. succeeded goto 2. If it fails
goto 3b.
Currently, we were sending errors in Select binary format,
which is incompatible with AWS S3 behavior, errors in binary
are sent after HTTP status code is already 200 OK - i.e it
happens during the evaluation of the record reader.
This commit increases storage REST requests to 5 minutes, this includes
the opening TCP connection, and sending/receiving data. This will reduce
clients receiving errors when the server is under high load.
Different gateway implementations due to different backend
API errors, might return different unsupported errors at
our handler layer. Current code posed a problem for us because
this information was lost and we would convert it to InternalError
in this situation all S3 clients end up retrying the request.
To avoid this unexpected situation implement a way to support
this cleanly such that the underlying information is not lost
which is returned by gateway.
Bucket metadata healing in the current code was executed multiple
times each time for a given set. Bucket metadata just like
objects are hashed in accordance with its name on any given set,
to allow hashing to play a role we should let the top level
code decide where to navigate.
Current code also had 3 bucket metadata files hardcoded, whereas
we should make it generic by listing and navigating the .minio.sys
to heal such objects.
We also had another bug where due to isObjectDangling changes
without pre-existing bucket metadata files, we were erroneously
reporting it as grey/corrupted objects.
This PR fixes all of the above items.
This PR also adds some comments and simplifies
the code. Primary handling is done to ensure
that we make sure to honor cached buffer.
Added unit tests as well
Fixes#7141
- Staging buffer is flushed every 500ms. In cases where the result
records are slowly generated (e.g. when a where condition
matches very few records), this change causes the server to send
results even though the staging buffer is not full.
- Refactor messageWriter code to use simpler channel based
co-ordination instead of atomic variables.
foo.CORRUPTED should never be created because when
multiple sets are involved we would hash the file
to wrong a location, this PR removes the code.
But allows DeleteBucket() to work properly to delete
dangling buckets/objects. Also adds another option
to Healing where a user needs to specify `--remove`
such that all dangling objects will be deleted with
user confirmation.
This change adds support for casting strings to Timestamp via CAST:
`CAST('2010T' AS TIMESTAMP)`
It also implements the following date-time functions:
- UTCNOW()
- DATE_ADD()
- DATE_DIFF()
- EXTRACT()
For values passed to these functions, date-types are automatically
inferred.
ListObjectParts is using xl.readXLMetaParts which picks the first
xl meta found in any disk, which is an inconsistent information.
E.g.: In a middle of a multipart upload, one node can go offline
and get back later with an outdated multipart information.
This commit fixes the computation of Before/After healing state
for empty directories.
Issues before the commit:
- Before state doesn't reflect the real status (no StatVol() called)
- For any MakeVol() error, healObjectDir is exited directly, which is
wrong.
Currently during a heal of a bucket, if one disk is offline an empty endpoint entry is added.
Then another entry with the missing endpoint is also added.
This results in more entries than disks being added.
Code that adds empty endpoint has been removed.
Collect historic cpu and mem stats. Also, use actual values
instead of formatted strings while returning to the client. The string
formatting prevents values from being processed by the server or
by the client without parsing it.
This change will allow the values to be processed (eg.
compute rolling-average over the lifetime of the minio server)
and offloads the formatting to the client.
We made a change previously in #7111 which moved support
for AWS envs only for AWS S3 endpoint. Some users requested
that this be added back to Non-AWS endpoints as well as
they require separate credentials for backend authentication
from security point of view.
More than one client can't use the same clientID for MQTT connection.
This causes problem in distributed deployments where config is shared
across nodes, as each Minio instance tries to connect to MQTT using the
same clientID.
This commit removes the clientID field in config, and allows
MQTT client to create random clientID for each node.
Batching records into a single SQL Select message in the response
leads to significant speed up as the message header overhead is made
negligible.
This change leads to a speed up of 3-5x for queries that select many
small records.
- New parser written from scratch, allows easier and complete parsing
of the full S3 Select SQL syntax. Parser definition is directly
provided by the AST defined for the SQL grammar.
- Bring support to parse and interpret SQL involving JSON path
expressions; evaluation of JSON path expressions will be
subsequently added.
- Bring automatic type inference and conversion for untyped
values (e.g. CSV data).
This situation happens only in gateway nas which supports
etcd based `config.json` to support all FS mode features.
The issue was we would try to migrate something which doesn't
exist when etcd is configured which leads to inconsistent
server configs in memory.
This PR fixes this situation by properly loading config after
initialization, avoiding backend disk config migration to be
done only if etcd is not configured.
If it does happen that we have a lot files in '.minio.sys/tmp',
minio startup might block deleting this folder. Rename and
delete in background instead to allow Minio to start serving
requests.
To avoid a large number of concurrent connections between minio
servers and to reduce CPU pressure, it is better to limit the number
of objects healed in parallel to number_of_CPUs.
Requirements like being able to run minio gateway in ec2
pointing to a Minio deployment wouldn't work properly
because IAM creds take precendence on ec2.
Add checks such that we only enable AWS specific features
if our backend URL points to actual AWS S3 not S3 compatible
endpoints.
Returning unexpected errors can cause problems for config handling,
which is what led gateway deployments with etcd to misbehave and
had stopped working properly
- Default support for S3 dualstack endpoints (IPv6 support)
- Support granular policy conditionals in List operations
- Support proxy cookies for stickiness
Deployment ID is not copied into new formats after healing format. Although,
this is not critical since a new deployment ID will be generated and set in the
next cluster restart, it is still much better if we don't change the deployment
id of a cluster for a better tracking.
Fix regexp matcher for special assets for the browser to clash with
less of the object namespace.
Assets should now be loaded with the /minio/ prefix. Previously,
favicon.ico (and others) could be loaded at any path matching
/minio/*/favicon.ico. This clashes with a large part of the object
namespace. With this change, /minio/favicon.ico will serve the favicon
but not /minio/mybucket/favicon.ico
Fixes#7077
This changes causes `getRootCAs` to always load system-wide CAs.
Any additional custom CAs (at `certs/CA/`) are added to the certificate pool
of system CAs.
The previous behavior was incorrect since all no system-wide CAs were
loaded if either there were CAs under `certs/CA` or the `certs/CA`
directory didn't exist at all.
Also add a cross compile script to test always cross
compilation for some well known platforms and architectures
, we support out of box compilation of these platforms even
if we don't make an official release build.
This script is to avoid regressions in this area when we
add platform dependent code.
This PR supports iam and bucket policies to have
policy variable replacements in resource and
condition key values.
For example
- ${aws:username}
- ${aws:userid}
Health checking programs very frequently use /minio/health/live
to check health, hence we can avoid doing StorageInfo() and
ListBuckets() for FS/Erasure backend.
* Use 0-byte file for bitrot verification of whole-file-bitrot files
Also pass the right checksum information for bitrot verification
* Copy xlMeta info from latest meta except []checksums and []Parts while healing
Simplify parallelReader.Read() which also fixes previous
implementation where it was returning before all the parallel
reading go-routines had terminated which caused race conditions.
When auto-encryption is turned on, we pro-actively add SSEHeader
for all PUT, POST operations. This is unusual for V2 signature
calculation because V2 signature doesn't have a pre-defined set
of signed headers in the request like V4 signature. According to
V2 we should canonicalize all incoming supported HTTP headers.
Make sure to validate signatures before we mutate http headers
This commit adds some documentation about the design of the
SSE-C and SSE-S3 implementation. It describes how the Minio server
encrypt objects and manages keys.
Deprecate the use of Admin Peers concept and migrate all peer
communication to Notification subsystem. This finally allows
for a common subsystem for all peer notification in case of
distributed server deployments.
Before this change the CopyObjectHandler and the CopyObjectPartHandler
both looked for a `versionId` parameter on the `X-Amz-Copy-Source` URL
for the version of the object to be copied on the URL unescaped version
of the header. This meant that files that had question marks in were
truncated after the question mark so that files with `?` in their
names could not be server side copied.
After this change the URL unescaping is done during the parsing of the
`versionId` parameter which fixes the problem.
This change also introduces the same logic for the
`X-Amz-Copy-Source-Version-Id` header field which was previously
ignored, namely returning an error if it is present and not `null`
since minio does not currently support versions.

When source is encrypted multipart object and the parts are not
evenly divisible by DARE package block size, target encrypted size
will not necessarily be the same as encrypted source object.
This commit removes old code preventing PUT requests with '/' as a path,
because this is not needed anymore after the introduction of the virtual
host style in Minio server code.
'PUT /' when global domain is not configured already returns 405 Method
Not Allowed http error.
This PR adds pass-through, single encryption at gateway and double
encryption support (gateway encryption with pass through of SSE
headers to backend).
If KMS is set up (either with Vault as KMS or using
MINIO_SSE_MASTER_KEY),gateway will automatically perform
single encryption. If MINIO_GATEWAY_SSE is set up in addition to
Vault KMS, double encryption is performed.When neither KMS nor
MINIO_GATEWAY_SSE is set, do a pass through to backend.
When double encryption is specified, MINIO_GATEWAY_SSE can be set to
"C" for SSE-C encryption at gateway and backend, "S3" for SSE-S3
encryption at gateway/backend or both to support more than one option.
Fixes#6323, #6696
This is part of implementation for mc admin health command. The
ServerDrivesPerfInfo() admin API returns read and write speed
information for all the drives (local and remote) in a given Minio
server deployment.
Part of minio/mc#2606
It can happen with erroneous clients which do not send `Host:`
header until 4k worth of header bytes have been read. This can lead
to Peek() method of bufio to fail with ErrBufferFull.
To avoid this we should make sure that Peek buffer is as large as
our maxHeaderBytes count.

MinIO cannot make the determination as to whether your application's usage of MinIO is in compliance with the AGPLv3 license requirements. You should instead rely on your own legal counsel or licensing specialists to audit and ensure your application is in compliance with the licenses of MinIO and all other open-source projects with which your application integrates or interacts. We understand that AGPLv3 licensing is complex and nuanced. It is for that reason we strongly encourage using experts in licensing to make any such determinations around compliance instead of relying on apocryphal or anecdotal advice.
[MinIO Commercial Licensing](https://min.io/pricing) is the best option for applications that trigger AGPLv3 obligations (e.g. open sourcing your application). Applications using MinIO - or any other OSS-licensed code - without validating their usage do so at their own risk.

We are not making any statements or representations about the suitability of this code or build in relation to the FIPS 140-2 standard. Interested users will have to evaluate for themselves whether this is useful for their own purposes.
Minio is an object storage server released under Apache License v2.0. It is compatible with Amazon S3 cloud storage service. It is best suited for storing unstructured data such as photos, videos, log files, backups and container / VM images. Size of an object can range from a few KBs to a maximum of 5TB.
MinIO is a High Performance Object Storage released under GNU Affero General Public License v3.0. It is API compatible with Amazon S3 cloud storage service. Use MinIO to build high performance infrastructure for machine learning, analytics and application data workloads. To learn more about what MinIO is doing for AI storage, go to [AI storage documentation](https://min.io/solutions/object-storage-for-ai).
This README provides quickstart instructions on running MinIO on bare metal hardware, including container-based installations. For Kubernetes environments, use the [MinIO Kubernetes Operator](https://github.com/minio/operator/blob/master/README.md).
## Container Installation
Use the following commands to run a standalone MinIO server as a container.
Standalone MinIO servers are best suited for early development and evaluation. Certain features such as versioning, object locking, and bucket replication
require distributed deploying MinIO with Erasure Coding. For extended development and production, deploy MinIO with Erasure Coding enabled - specifically,
with a *minimum* of 4 drives per MinIO server. See [MinIO Erasure Code Overview](https://min.io/docs/minio/linux/operations/concepts/erasure-coding.html)
for more complete documentation.
## Docker Container
### Stable
```
docker pull minio/minio
docker run -p 9000:9000 minio/minio server /data
Run the following command to run the latest stable image of MinIO as a container using an ephemeral data volume:
```sh
podman run -p 9000:9000 -p 9001:9001 \
quay.io/minio/minio server /data --console-address ":9001"
```
### Edge
```
docker pull minio/minio:edge
docker run -p 9000:9000 minio/minio:edge server /data
```
Note: Docker will not display the autogenerated keys unless you start the container with the `-it`(interactive TTY) argument. Generally, it is not recommended to use autogenerated keys with containers. Please visit Minio Docker quickstart guide for more information [here](https://docs.minio.io/docs/minio-docker-quickstart-guide)
The MinIO deployment starts using default root credentials `minioadmin:minioadmin`. You can test the deployment using the MinIO Console, an embedded
object browser built into MinIO Server. Point a web browser running on the host machine to <http://127.0.0.1:9000> and log in with the
root credentials. You can use the Browser to create buckets, upload objects, and browse the contents of the MinIO server.
You can also connect using any S3-compatible tool, such as the MinIO Client `mc` commandline tool. See
[Test using MinIO Client `mc`](#test-using-minio-client-mc) for more information on using the `mc` commandline tool. For application developers,
see <https://min.io/docs/minio/linux/developers/minio-drivers.html> to view MinIO SDKs for supported languages.
> NOTE: To deploy MinIO on with persistent storage, you must map local persistent directories from the host OS to the container using the `podman -v` option. For example, `-v /mnt/data:/data` maps the host OS drive at `/mnt/data` to `/data` on the container.
## macOS
### Homebrew
Install minio packages using [Homebrew](http://brew.sh/)
Use the following commands to run a standalone MinIO server on macOS.

Use the following commands to compile and run a standalone MinIO server from source. Source installation is only intended for developers and advanced users. If you do not have a working Golang environment, please follow [How to install Golang](https://golang.org/doc/install). Minimum version required is [go1.21](https://golang.org/dl/#stable)
```sh
go get -u github.com/minio/minio
go install github.com/minio/minio@latest
```
## Allow port access for Firewalls
The MinIO deployment starts using default root credentials `minioadmin:minioadmin`. You can test the deployment using the MinIO Console, an embedded web-based object browser built into MinIO Server. Point a web browser running on the host machine to <http://127.0.0.1:9000> and log in with the root credentials. You can use the Browser to create buckets, upload objects, and browse the contents of the MinIO server.
By default Minio uses the port 9000 to listen for incoming connections. If your platform blocks the port by default, you may need to enable access to the port.
You can also connect using any S3-compatible tool, such as the MinIO Client `mc` commandline tool. See [Test using MinIO Client `mc`](#test-using-minio-client-mc) for more information on using the `mc` commandline tool. For application developers, see <https://min.io/docs/minio/linux/developers/minio-drivers.html> to view MinIO SDKs for supported languages.

See [MinIO Erasure Code Overview](https://min.io/docs/minio/linux/operations/concepts/erasure-coding.html) for more complete documentation.
For hosts with iptables enabled (RHEL, CentOS, etc), you can use `iptables`command to enable all traffic coming to specific ports. Use below command to allow
access to port 9000
MinIO strongly recommends *against* using compiled-from-source MinIO servers for production environments.
```sh
iptables -A INPUT -p tcp --dport 9000 -j ACCEPT
service iptables restart
```
## Deployment Recommendations
Below command enables all incoming traffic to ports ranging from 9000 to 9010.
### Allow port access for Firewalls

## Test using Minio Browser
Minio Server comes with an embedded web based object browser. Point your web browser to http://127.0.0.1:9000 ensure your server has started successfully.
For hosts with iptables enabled (RHEL, CentOS, etc), you can use `iptables` command to enable all traffic coming to specific ports. Use below command to allow
access to port 9000
## Test using Minio Client `mc`
`mc` provides a modern alternative to UNIX commands like ls, cat, cp, mirror, diff etc. It supports filesystems and Amazon S3 compatible cloud storage services. Follow the Minio Client [Quickstart Guide](https://docs.minio.io/docs/minio-client-quickstart-guide) for further instructions.
```sh
iptables -A INPUT -p tcp --dport 9000 -j ACCEPT
service iptables restart
```
## Pre-existing data
When deployed on a single drive, Minio server lets clients access any pre-existing data in the data directory. For example, if Minio is started with the command `minio server /mnt/data`, any pre-existing data in the `/mnt/data` directory would be accessible to the clients.
Below command enables all incoming traffic to ports ranging from 9000 to 9010.
The above statement is also valid for all gateway backends.
```sh
iptables -A INPUT -p tcp --dport 9000:9010 -j ACCEPT
service iptables restart
```
## Test MinIO Connectivity
### Test using MinIO Console
MinIO Server comes with an embedded web based object browser. Point your web browser to <http://127.0.0.1:9000> to ensure your server has started successfully.
> NOTE: MinIO runs console on random port by default, if you wish to choose a specific port use `--console-address` to pick a specific interface and port.
### Things to consider
MinIO redirects browser access requests to the configured server port (i.e. `127.0.0.1:9000`) to the configured Console port. MinIO uses the hostname or IP address specified in the request when building the redirect URL. The URL and port *must* be accessible by the client for the redirection to work.
For deployments behind a load balancer, proxy, or ingress rule where the MinIO host IP address or port is not public, use the `MINIO_BROWSER_REDIRECT_URL` environment variable to specify the external hostname for the redirect. The LB/Proxy must have rules for directing traffic to the Console port specifically.
For example, consider a MinIO deployment behind a proxy `https://minio.example.net`, `https://console.minio.example.net` with rules for forwarding traffic on port :9000 and :9001 to MinIO and the MinIO Console respectively on the internal network. Set `MINIO_BROWSER_REDIRECT_URL` to `https://console.minio.example.net` to ensure the browser receives a valid reachable URL.
`mc` provides a modern alternative to UNIX commands like ls, cat, cp, mirror, diff etc. It supports filesystems and Amazon S3 compatible cloud storage services. Follow the MinIO Client [Quickstart Guide](https://min.io/docs/minio/linux/reference/minio-mc.html#quickstart) for further instructions.
## Upgrading MinIO
Upgrades require zero downtime in MinIO, all upgrades are non-disruptive, all transactions on MinIO are atomic. So upgrading all the servers simultaneously is the recommended way to upgrade MinIO.
> NOTE: requires internet access to update directly from <https://dl.min.io>, optionally you can host any mirrors at <https://my-artifactory.example.com/minio/>
- For deployments that installed the MinIO server binary by hand, use [`mc admin update`](https://min.io/docs/minio/linux/reference/minio-mc-admin/mc-admin-update.html)
```sh
mc admin update <minio alias, e.g., myminio>
```
- For deployments without external internet access (e.g. airgapped environments), download the binary from <https://dl.min.io> and replace the existing MinIO binary let's say for example `/opt/bin/minio`, apply executable permissions `chmod +x /opt/bin/minio` and proceed to perform `mc admin service restart alias/`.
- For installations using Systemd MinIO service, upgrade via RPM/DEB packages **parallelly** on all servers or replace the binary lets say `/opt/bin/minio` on all nodes, apply executable permissions `chmod +x /opt/bin/minio` and process to perform `mc admin service restart alias/`.
### Upgrade Checklist
- Test all upgrades in a lower environment (DEV, QA, UAT) before applying to production. Performing blind upgrades in production environments carries significant risk.
- Read the release notes for MinIO *before* performing any upgrade, there is no forced requirement to upgrade to latest release upon every release. Some release may not be relevant to your setup, avoid upgrading production environments unnecessarily.
- If you plan to use `mc admin update`, MinIO process must have write access to the parent directory where the binary is present on the host system.
- `mc admin update` is not supported and should be avoided in kubernetes/container environments, please upgrade containers by upgrading relevant container images.
- **We do not recommend upgrading one MinIO server at a time, the product is designed to support parallel upgrades please follow our recommended guidelines.**
