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.
* return errFaultyDisk for DiskInfo() call

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.
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
calculating the cycle.

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 a distributed setup, a DiskInfo REST call to an unformatted disk
returns an error with no disk information, such as the disk endpoint
URL, which is unexpected.
metadata headers can have headers without values
as per AWS S3 spec however, we need to skip some
headers that do not have values that potentially
can have empty values set.
small setups do not return appropriate errors when speedtest
cannot run on small tiny setups, allow the tests to fail
appropriately more pro-actively.
many users bring toy setups, this PR simply returns an error
in such situations.
healing disks take active I/O it is possible
that deleted objects might stay in .trash
folder for a really long time until the drive
is fully healed.
this PR changes it such that we are making sure
we purge the active content written to these
disks as well.
- speedtest logs calls that were canceled
spuriously, in situations where it should
be ignored.
- all errors of interest are always sent back
to the client there is no need to log them
on the server console.
- PUT failures should negate the increments
such that GET is not attempted on unsuccessful
calls.
- do not attempt MRF on speedtest objects.
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.
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.
Regression from #13990
When more than one gateway reads and writes from the same mount point
and there is a load balancer pointing to those gateways. Each gateway
will try to create its own temporary append file but fails to clear it later
when not needed.
This commit creates a routine that checks all upload IDs saved in
multipart directory and remove any stale entry with the same upload id
in the memory and in the temporary background append folder as well.
Enabled with `mc admin config set alias/ api gzip_objects=on`
Standard filtering applies (1K response minimum, not compressed content
type, not range request, gzip accepted by client).
The current code considers a pool with all root disks to be as part
of a testing environment even if there are other pools with mounted
disks. This will result to illegitimate writing in root disks.
Fix this by simplifing the logic: require MINIO_CI_CD in order to skip
root disk check.
MinIO configuration is loaded after the initialization of the server
handlers, which will miss the initialization of the bucket forwarder
handler.
Though the federation is deprecated, let's fix this for the time being.
S3 spec returns x-amz-restore header in HEAD/GET object with the
following format:
```
x-amz-restore: ongoing-request="false", expiry-date="Fri, 21 Dec 2012
00:00:00 GMT"
```
This commit adds quotes as the current code does not support it. It will
also supports the old format saved in the disk (in xl.meta) for backward
compatibility.
A regression removed support of federation in the gateway mode.
Enable it again.
Federation is deprecated for a while but let's fix this for the time being.
Deleting bulk objects had an issue since the relevant versionID
is not passed through the layers to ensure that the dangling
object purge actually works cleanly.
This is a continuation of quorum related error returned by
multi-object delete API from #14248
This PR ensures that we pass down correct information as
well as extend the scope of dangling object detection.
When setting a config of a particular sub-system, validate the existing
config and notification targets of only that sub-system, so that
existing errors related to one sub-system (e.g. notification target
offline) do not result in errors for other sub-systems.
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.
startup speed-up, currently getFormatErasureInQuorum()
would spend up to 2-3secs when there are 3000+ drives
for example in a setup, simplify this implementation
to use drive counts.
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.
This can happen when an object is queued, but no info can be fetched.
Fixes#14190
The healing code repeatedly tries to heal a root disk when it is empty
the reason is that connectEndpoint() returns errUnformattedDisk even
if the disk is a root disk. Changing that to returning another error
will avoid queueing the disk to the healing code in each connect disks
iteration.
some upgraded objects might not get listed due
to different quorum ratios across objects.
make sure to list all objects that satisfy the
maximum possible quorum.
This change allows the MinIO server to lookup users in different directory
sub-trees by allowing specification of multiple search bases separated by
semicolons.
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.
Regression caused by #13454 - that part didn't optimize anything anyway.
Publish storage functions latency to help compare the performance

- 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,
groups when an empty site was added.
- Add site replication for groups and users when they
are disabled and enabled.
- Add support for replicating bucket quota config.
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
workloads, need the following option to disable
O_DIRECT for a more effective usage of the kernel
page-cache.
However this optional should be used in very specific
situations only, and shouldn't be enabled on all
servers.
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.
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
internal IDentity Provider.
- Internal IDP IAM users and groups will now be replicated to all members of the
set of replicated sites.
- 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).
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.
The AddUser() API endpoint was accepting a policy field.
This API is used to update a user's secret key and account
status, and allows a regular user to update their own secret key.
The policy update is also applied though does not appear to
be used by any existing client-side functionality.
This fix changes the accepted request body type and removes
the ability to apply policy changes as that is possible via the
policy set API.
NOTE: Changing passwords can be disabled as a workaround
for this issue by adding an explicit "Deny" rule to disable the API
for users.
This PR is an attempt to make this configurable
as not all situations have same level of tolerable
delta, i.e disks are replaced days apart or even
hours.
There is also a possibility that nodes have drifted
in time, when NTP is not configured on the system.
data shards were wrong due to a healing bug
reported in #13803 mainly with unaligned object
sizes.
This PR is an attempt to automatically avoid
these shards, with available information about
the `xl.meta` and actually disk mtime.
- When using MinIO's internal IDP, STS credential permissions did not check the
groups of a user.
- Also fix bug in policy checking in AccountInfo call
Also log all the missed events and logs instead of silently
swallowing the events.
Bonus: Extend the logger webhook to support mTLS
similar to audit webhook target.
- r.ulock was not locked when r.UsageCache was being modified
Bonus:
- simplify code by removing some unnecessary clone methods - we can
do this because go arrays are values (not pointers/references) that are
automatically copied on assignment.
- remove some unnecessary map allocation calls
data-structures were repeatedly initialized
this causes GC pressure, instead re-use the
collectors.
Initialize collectors in `init()`, also make
sure to honor the cache semantics for performance
requirements.
Avoid a global map and a global lock for metrics
lookup instead let them all be lock-free unless
the cache is being invalidated.
When STS credentials are created for a user, a unique (hopefully stable) parent
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.
- 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
if latest is delete marker and delimiter is not provided.
ListObjectVersions() should list a delete-marked folder
even if latest is delete marker and delimiter is not
provided.
Enhance further versioning listing on the buckets
request.Form uses less memory allocation and avoids gorilla mux matching
with weird characters in parameters such as '\n'
- Remove Queries() to avoid matching
- Ensure r.ParseForm is called to populate fields
- Add a unit test for object names with '\n'
delete marked objects should not be considered
for listing when listing is delimited, this issue
as introduced in PR #13804 which was mainly to
address listing of directories in listing when
delimited.
This PR fixes this properly and adds tests to
ensure that we behave in accordance with how
an S3 API behaves for ListObjects() without
versions.
Save part.1 for writebacks in a separate folder
and move it to cache dir atomically while saving
the cache metadata. This is to avoid GC mistaking
part.1 as orphaned cache entries and purging them.
This PR also fixes object size being overwritten during
retries for write-back mode.
- deleting policies was deleting all LDAP
user mapping, this was a regression introduced
in #13567
- deleting of policies is properly sent across
all sites.
- remove unexpected errors instead embed the real
errors as part of the 500 error response.
- 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.
fixes#13834
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.
single object delete was not working properly
on a bucket when versioning was suspended,
current version 'null' object was never removed.
added unit tests to cover the behavior
fixes#13783
totalDrives reported in speedTest result were wrong
for multiple pools, this PR fixes this.
Bonus: add support for configurable storage-class, this
allows us to test REDUCED_REDUNDANCY to see further
maximum throughputs across the cluster.
- 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`).

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.

currently getReplicationConfig() failure incorrectly
returns error on unexpected buckets upon upgrade, we
should always calculate usage as much as possible.

and when we are retrying skip the buckets that
are already marked done by using the tracked buckets.

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 adding/updating/deleting a version with only header deserialization.
* Reduces allocations on conversion to FileInfo(s).

default-populated during unmarshalling of the JSON.

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.

Borrowed idea from Go's usage of this
optimization for ReadFrom() on client

io.Copy() allocates for generic copy
from a reader to writer.

- Ensure all actions accessing storage lock properly.
- Behavior change: policies can be deleted only when they
are not associated with any active credentials.
- The race happens with a goroutine that refreshes IAM cache data from storage.
- It could lead to deleted users re-appearing as valid live credentials.
- This change also causes CI to run tests without a race flag (in addition to
running it with).
deleting collection of versions belonging
to same object, we can avoid re-reading
the xl.meta from the disk instead purge
all the requested versions in-memory,
the tradeoff is to allocate a map to de-dup
the versions, allow disks to be read only
once per object.
additionally reduce the data transfer between
nodes by shortening msgp data values.
- combine similar looking functionalities into single
handlers, and remove unnecessary proxying of the
requests at handler layer.
- remove bucket forwarding handler as part of default setup
add it only if bucket federation is enabled.

Removes RLock/RUnlock for updating metadata,
since we already take a write lock to update
metadata, this change removes reading of xl.meta
as well as an additional lock, the performance gain
should increase 3x theoretically for
- PutObjectRetention
- PutObjectLegalHold
This optimization is mainly for Veeam like
workloads that require a certain level of iops
from these API calls, we were losing iops.
read/writers are not concurrent in handlers
and self contained - no need to use atomics on
them.
avoids unnecessary contentions where it's not
required.
Logger targets were not race protected against concurrent updates from for example `HTTPConsoleLoggerSys`.
Restrict direct access to targets and make slices immutable so a returned slice can be processed safely without locks.
As we use etcd's watch interface, we do not need the
network notifications as they are no-ops anyway.
Bonus: Remove globalEtcdClient global usage in IAM
IAMSys is a higher-level object, that should not be called by the lower-level
storage API interface for IAM. This is to prepare for further improvements in
IAM code.
etcd operations, get/put/delete, should be logged when failed
with errors other than not found error. It will make it easier to
see connections issues from MinIO to etcd.
Refresh was doing a linear scan of all locked resources. This was adding

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
of SSE-KMS for auto-encryption.
This PR however also proceeds to simplify the loading
of various subsystems such as
- globalNotificationSys
- globalTargetSys
converge them directly into single bucket metadata sys
loader, once that is loaded automatically every other
target should be loaded and configured properly.

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

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.

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

Replication was not working properly for encrypted

We need to make sure to preserve etag such that replication

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

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

that such type of listObjects() always behaves similar to a
headObject() call.
this addresses a regression from #12984
which only addresses flat key from single

added extra tests as well to cover all
these scenarios.
- deletes should always Sweep() for tiering at the
end and does not need an extra getObjectInfo() call
- puts, copy and multipart writes should conditionally
do getObjectInfo() when tiering targets are configured
- introduce 'TransitionedObject' struct for ease of usage
and understanding.
- 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
end with `/` this causes large recursive listings
without any filtering, to fix this filtering make
sure to set the filter prefix appropriately.
also do not navigate folders at top level that do
not match the filter prefix, entries don't need
to match prefix since they are never prefixed
with the prefix anyways.
The previous code removes SVC/STS accounts for ldap users that do not
exist anymore in LDAP server. This commit will actually re-evaluate
filter as well if it is changed and remove all local SVC/STS accounts
beloning to the ldap user if the latter is not eligible for the
search filter anymore.
For example: the filter selects enabled users among other criteras in
the LDAP database, if one ldap user changes his status to disabled
later, then associated SVC/STS accounts will be removed because that user
does not meet the filter search anymore.

This happens because of a change added where any sub-credential

always be an owner, you cannot generate credentials with lower
session policy to restrict their access.
This doesn't affect user service accounts created with regular
users, LDAP or OpenID
Use `readMetadata` when reading version
information without data requested.
Reduces IO on inlined data.
Bonus: Inline compressed data as well when
compression is enabled.
- avoid extra lookup for 'xl.meta' since we are
definitely sure that it doesn't exist.
- use this in newMultipartUpload() as well
- also additionally do not write with O_DSYNC
to avoid loading the drives, instead create
'xl.meta' for listing operations without
O_DSYNC since these are ephemeral objects.
- do the same with newMultipartUpload() since
it gets synced when the PutObjectPart() is
attempted, we do not need to tax newMultipartUpload()
instead.
removes unexpected features from regular putObject() such as
- increasing parity when disks are down, avoids
a lot of DiskInfo() calls.
- triggering MRF for metacache objects
if disks are offline
- avoiding renames from temporary location
to actual namespace, not needed since
metacache files are unique.
Disregard interfaces that are down when selecting bind addresses
Windows often has a number of disabled NICs used for VPN and other services.
This often causes minio to select an address for contacting the console that is on a disabled (virtual) NIC.
This checks if the interface is up before adding it to the pool on Windows.

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
disksWithAllParts() does not know-how
to deal with delete markers, add support
for that.
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.
When configured in Lookup Bind mode, the server now periodically queries the
LDAP IDP service to find changes to a user's group memberships, and saves this
info to update the access policies for all temporary and service account
credentials belonging to LDAP users.
Add a new goroutine file which has another printing format. We need it

when TLS is configured using IPs directly

the server is configured with TLS certs but
the certs only have domain certs.
Also additionally allow users to specify
a public accessible URL for console to talk
to MinIO i.e `MINIO_SERVER_URL` this would
allow them to use an external ingress domain
to talk to MinIO. This internally fixes few
problems such as presigned URL generation on
the console UI etc.
This needs to be done additionally for any
MinIO deployments that might have a much more
stricter requirement when running in standalone
mode such as FS or standalone erasure code.
This method is used to add expected expiration and transition time
for an object in GET/HEAD Object response headers.
Also fixed bugs in lifecycle.PredictTransitionTime and
getLifecycleTransitionTier in handling current and
non-current versions.
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/
[2021-07-12 17:15:50 PDT] 160B 48/fb/48fbc0e6-3a73-458b-9337-8e722c619ca4

```
In case of non-distributed setup, if the server start command contains a
`--console-address` flag and its value contains a hostname, it is not
getting anonymized.
Fixed by replacing the console host also with `server1`
This commit gathers MRF metrics from
all nodes in a cluster and return it to the caller. This will show information about the
number of objects in the MRF queues
waiting to be healed.
In case of replication healing, we always store completed status in the
object metadata, which is wrong because replication could fail in the
further retries.
Ensure that hostnames / ip addresses are not printed in the subnet
health report. Anonymize them by replacing them with `servern` where `n`
represents the position of the server in the pool.
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.
Gzip responses if appropriate, except GetObject requests.
List reponses has an almost 10:1 compression ratio with no

previous PR incorrectly changed rename() from
tmp to -> tmp/.trash/uuid, since it is self
referential - to clear this up make sure its
renamed to a separate folder and deleted
in background - just like before.
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.

It makes sense that a node that has multiple disks starts when one
disk fails, returning an i/o error for example. This commit will make this

Due to incorrect KMS context constructed, we need to add

to fix already migrated deployments.
Bonus remove double migration is avoided in gateway mode
for etcd, instead do it once in iam.Init(), also simplify
the migration by not migrating STS users instead let the
clients regenerate them.
- Adds versioning support for S3 based remote tiers that have versioning
enabled. This ensures that when reading or deleting we specify the specific
version ID of the object. In case of deletion, this is important to ensure that
the object version is actually deleted instead of simply being marked for
deletion.
- Stores the remote object's version id in the tier-journal. Tier-journal file
version is not bumped up as serializing the new struct version is
compatible with old journals without the remote object version id.
- `storageRESTVersion` is bumped up as FileInfo struct now includes a
`TransitionRemoteVersionID` member.
- Azure and GCS support for this feature will be added subsequently.

Also adding an API to allow resyncing replication when
existing object replication is enabled and the remote target
is entirely lost. With the `mc replicate reset` command, the
objects that are eligible for replication as per the replication
config will be resynced to target if existing object replication
is enabled on the rule.
This is to ensure that there are no projects
that try to import `minio/minio/pkg` into
their own repo. Any such common packages should
go to `https://github.com/minio/pkg`
IAM not initialized doesn't mean we can't still
read the content from the disk, we should just
allow the request to go-through if object layer
is initialized.
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

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.

multi-disk clusters initialize buffer pools

not useful, for a running server instance. As this

this change ensures that buffers across sets

quite a lot of memory on large drive setups.
In lieu of new changes coming for server command line, this

Bonus: for really large streams use larger buffer for

- 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.

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.

the overall complexity within the MinIO server and there
is no need to maintain two separate client implementations.

This commit enforces the usage of AES-256
for config and IAM data en/decryption in FIPS
mode.
Further, it improves the implementation of
`fips.Enabled` by making it a compile time
constant. Now, the compiler is able to evaluate
the any `if fips.Enabled { ... }` at compile time
and eliminate unused code.

p.writers is a verbatim value of bitrotWriter
backed by a pipe() that should never be nil'ed,
instead use the captured errors to skip the writes.
additionally detect also short writes, and reject
them as errors.
currently GetUser() returns 403 when IAM is not initialized
this can lead to applications crashing, instead return 503
so that the applications can retry and backoff.

as there is no automatic way to detect if there
is a root disk mounted on / or /var for the container
environments due to how the root disk information
is masked inside overlay root inside container.
this PR brings an environment variable to set
root disk size threshold manually to detect the
root disks in such situations.
This commit fixes a bug in the single-part object decryption
that is triggered in case of SSE-KMS. Before, it was assumed
that the encryption is either SSE-C or SSE-S3. In case of SSE-KMS
the SSE-C branch was executed. This lead to an invalid SSE-C
algorithm error.
This commit fixes this by inverting the `if-else` logic.
Now, the SSE-C branch only gets executed when SSE-C headers
are present.

This commit fixes a bug introduced by af0c65b.
When there is no / an empty client-provided SSE-KMS
context the `ParseMetadata` may return a nil map
(`kms.Context`).
When unsealing the object key we must check that
the context is nil before assigning a key-value pair.

UpdateServiceAccount ignores updating fields when not passed from upper
layer, such as empty policy, empty account status, and empty secret key.
This PR will check for a secret key only if it is empty and add more
check on the value of the account status.

This commit adds basic SSE-KMS support.
Now, a client can specify the SSE-KMS headers
(algorithm, optional key-id, optional context)
such that the object gets encrypted using the
SSE-KMS method. Further, auto-encryption now
defaults to SSE-KMS.
This commit does not try to do any refactoring
and instead tries to implement SSE-KMS as a minimal
change to the code base. However, refactoring the entire
crypto-related code is planned - but needs a separate
effort.

It is possible in some scenarios that in multiple pools,
two concurrent calls for the same object as a multipart operation
can lead to duplicate entries on two different pools.
This PR fixes this
- hold locks to serialize multiple callers so that we don't race.
- make sure to look for existing objects on the namespace as well
not just for existing uploadIDs
When running MinIO server without LDAP/OpenID, we should error out when
the code tries to create a service account for a non existant regular
user.
Bonus: refactor the check code to be show all cases more clearly

avoid time_wait build up with getObject requests if there are
pending callers and they timeout, can lead to time_wait states
Bonus share the same buffer pool with erasure healing logic,
additionally also fixes a race where parallel readers were
never cleanup during Encode() phase, because pipe.Reader end
was never closed().
Added closer right away upon an error during Encode to make
sure to avoid racy Close() while stream was still being
Read().
This commit fixes a bug when parsing the env. variable
`MINIO_KMS_SECRET_KEY`. Before, the env. variable
name - instead of its value - was parsed. This (obviously)
did not work properly.

cleanup functions should never be cleaned before the reader is
instantiated, this type of design leads to situations where order
of lockers and places for them to use becomes confusing.
Allow WithCleanupFuncs() if the caller wishes to add cleanupFns
to be run upon close() or an error during initialization of the
reader.
Also make sure streams are closed before we unlock the resources,
this allows for ordered cleanup of resources.
upon errors to acquire lock context would still leak,
since the cancel would never be called. since the lock
is never acquired - proactively clear it before returning.
failed queue should be used for retried requests to
avoid cascading the failures into incoming queue, this
would allow for a more fair retry for failed replicas.
Additionally also avoid taking context in queue task
to avoid confusion, simplifies its usage.
There can be situations where replication completed but the
`X-Amz-Replication-Status` metadata update failed such as
when the server returns 503 under high load. This object version will
continue to be picked up by the scanner and replicateObject would perform
no action since the versions match between source and target.
The metadata would never reflect that replication was successful
without this fix, leading to repeated re-queuing.
This commit enhances the docs about IAM encryption.
It adds a quick-start section that explains how to
get started quickly with `MINIO_KMS_SECRET_KEY`
instead of setting up KES.
It also removes the startup message that gets printed
when the server migrates IAM data to plaintext.
We will point this out in the release notes.

OpenID connect generated service accounts do not work
properly after console logout, since the parentUser state
is lost - instead use sub+iss claims for parentUser, according
to OIDC spec both the claims provide the necessary stability
across logins etc.
Currently, only credentials could be updated with
`mc admin bucket remote edit`.
Allow updating synchronous replication flag, path,
bandwidth and healthcheck duration on buckets, and
a flag to disable proxying in active-active replication.
* lock: Always cancel the returned Get(R)Lock context
There is a leak with cancel created inside the locking mechanism. The
cancel purpose was to cancel operations such erasure get/put that are
holding non-refreshable locks.
This PR will ensure the created context.Cancel is passed to the unlock
API so it will cleanup and avoid leaks.
* locks: Avoid returning nil cancel in local lockers
Since there is no Refresh mechanism in the local locking mechanism, we
do not generate a new context or cancel. Currently, a nil cancel
function is returned but this can cause a crash. Return a dummy function
instead.

This commit reverts a change that added support for
parsing base64-encoded keys set via `MINIO_KMS_MASTER_KEY`.
The env. variable `MINIO_KMS_MASTER_KEY` is deprecated and
should ONLY support parsing existing keys - not the new format.
Any new deployment should use `MINIO_KMS_SECRET_KEY`. The legacy
env. variable `MINIO_KMS_MASTER_KEY` will be removed at some point
in time.
