Publish storage functions latency to help compare the performance
of different disks in a single deployment.
e.g.:
```
minio_node_disk_latency_us{api="storage.WalkDir",disk="/tmp/xl/1",server="localhost:9001"} 226
minio_node_disk_latency_us{api="storage.WalkDir",disk="/tmp/xl/2",server="localhost:9002"} 1180
minio_node_disk_latency_us{api="storage.WalkDir",disk="/tmp/xl/3",server="localhost:9003"} 1183
minio_node_disk_latency_us{api="storage.WalkDir",disk="/tmp/xl/4",server="localhost:9004"} 1625
```
- 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

- Remove Queries() to avoid matching

delete marked objects should not be considered
for listing when listing is delimited, this issue
as introduced in PR #13804 which was mainly to

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

- 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.

- 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.
This would result in `Error: invalid input: magic number mismatch` when reading back.
On non-erasure backends store index as base64.
The httpStreamResponse should not return until CloseWithError has been called.
Instead keep track of write state and skip writing/flushing if an error has occurred.
Fixes#13743
Regression from #13597 (not released)
Go's atomic.Value does not support `nil` type,
concrete type is necessary to avoid any panics with
the current implementation.
Also remove boolean to turn-off tracking of freezeCount.
an active running speedTest will reject all
new S3 requests to the server, until speedTest
is complete.
this is to ensure that speedTest results are
accurate and trusted.

FileInfo quorum shouldn't be passed down, instead
inferred after obtaining a maximally occurring FileInfo.
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
{
"Rules": [
{
"ID": "test-max-noncurrent",
"Status": "Enabled",
"Filter": {
"Prefix": "user-uploads/"
},
"NoncurrentVersionExpiration": {
"MaxNoncurrentVersions": 5
}
}
]
}
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.

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.

legacy objects in 'xl.json' after upgrade, should have
following sequence of events - bucket should have versioning
enabled and the object should have been overwritten with
another version of an object.
this situation was not handled, which would lead to older
objects to stay perpetually with "legacy" dataDir, however
these objects were readable by all means - there weren't

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.

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.
Improvements observed for 1kiB object reads.

```
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
up to significant delays in locking on high load systems with long
running requests.
Add a secondary index for O(log(n)) UID -> resource lookups.
Multiple resources are stored in consecutive strings.
Bonus fixes:
* On multiple Unlock entries unlock the write locks we can.
* Fix `expireOldLocks` skipping checks on entry after expiring one.
* Return fast on canTakeUnlock/canTakeLock.
* Prealloc some places.
We do not reliably know the length of compressed data, including headers.

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 added in #12947 when this part of the

Bonus:
- fix: AssumeRoleWithCertificate policy mapping and reload
AssumeRoleWithCertificate was not mapping to correct
policies even after successfully generating keys, since
the claims associated with this API were never looked up
properly. Ensure that policies are set appropriately.
- GetUser() API was not loading policies correctly based
on AccessKey based mapping which is true with OpenID
and AssumeRoleWithCertificate API.

Bonus: reduce retry duration for listing to 200ms
additionally optimize for IP only setups, avoid doing
unnecessary lookups if the Dial addr is an IP.

This also allows for overwrites which may not be possible

This PR brings two optimizations mainly
for page-cache build-up and how to avoid
getting OOM killed in the process. Although
these memories are reclaimable Linux is not
fast enough to reclaim them as needed on a
very busy system. fadvise is a system call
implemented in Linux to advise page-cache to
avoid overload as we get significant amount
of requests on the server.
- FADV_SEQUENTIAL tells that all I/O from now
is going to be sequential, allowing for more
resposive throughput.
- FADV_NOREUSE tells kernel to start removing
things for this 'fd' from page-cache.
An endpoint can be empty when a disk is offline or something

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.
fixes#13252
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.

When unable to load existing metadata new versions
would not be written. This would leave objects in a
permanently unrecoverable state
Instead, start with clean metadata and write the incoming data.
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.
Leads to some objects being inlined or not based on new metrics. Instead respect previous decision.
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
due to ETag mismatches.
This will allow objects to relinquish read lock held during
replication earlier if the target is known to be down
without waiting for connection timeout when replication
is attempted.
Stop async listing if we have not heard back from the client for 3 minutes.
This will stop spending resources on async listings when they are unlikely to get used.
If the client returns a new listing will be started on the second request.
Stop saving cache metadata to disk. It is cleared on restarts anyway. Removes all
load/save functionality
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.
For more details and examples refer to the docs/sts/tls.md
documentation.

Azure storage SDK uses http.Request feature which panics when the
request contains r.Form popuplated.
Azure gateway code creates a new request, however it modifies the

This commit simplifies shouldMeterRequest() to avoid setting
request.Form and avoid the crash.
console service should be shutdown last once all shutdown

A multi resources lock is a single lock UID with multiple associated

#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
parent users to stop working and lead to
credentials getting overwritten.

We are observing heavy system loads, potentially
locking the system up for periods when concurrent
listing operations are performed.
We place a per-disk lock on walk IO operations.
This will minimize the impact of concurrent listing
operations on the entire system and de-prioritize
them compared to other operations.
Single list operations should remain largely unaffected.
Some applications albeit poorly written rather than using headObject
rely on listObjects to check for existence of object, this unusual
request always has prefix=(to actual object) and max-keys=1

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

- 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

Disregard interfaces that are down when selecting bind addresses

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.

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

This needs to be done additionally for any
MinIO deployments that might have a much more
stricter requirement when running in standalone

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/

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.

with console addition users cannot login with
root credentials without etcd persistent layer,
allow a dummy store such that such functionalities
can be supported when running as non-persistent
manner, this enables all calls and operations.
MinIO might be running inside proxies, and
console while being on another port might not be
reachable on a specific port behind such proxies.
For such scenarios customize the redirect URL
such that console can be redirected to correct
proxy endpoint instead.

Download files from *any* bucket/path as an encrypted zip file.
The key is included in the response but can be separated so zip
and the key doesn't have to be sent on the same channel.
Requires https://github.com/minio/pkg/pull/6
Additional support for vendor-specific admin API
integrations for OpenID, to ensure validity of
credentials on MinIO.
Every 5minutes check for validity of credentials
on MinIO with vendor specific IDP.
DiskInfo() calls can stagger and wait if run
serially timing out 10secs per drive, to avoid
this lets check DiskInfo in parallel to avoid
delays when nodes get disconnected.
Fixes brought forward from https://github.com/minio/minio/pull/12605
Fixes resolution when an object is in prefix of another and one zone returns the directory and another the object.
Fixes resolution on single entries that arrive first, so resolution doesn't depend on order.
auditLog should be attempted right before the
return of the function and not multiple times
per function, this ensures that we only trigger
it once per function call.
if object was uploaded with multipart. This is to ensure that
GetObject calls with partNumber in URI request parameters
have same behavior on source and replication target.
also do not incorrectly double count
objExists unless its selected and it
matches with previous entry.
Bonus: change listQuorum to match with
AskDisks to ensure that we atleast by
default choose all the "drives" that
we asked is consistent.
Bonus: remove kms_kes as sub-system, since its ENV only.
- also fixes a crash with etcd cluster without KMS
configured and also if KMS decryption is missing.
backend-encrypted doesn't need to be explicitly healed anymore
since this file is deleted upon upgrade and migration to the
KMS based encrypted config/IAM credentials.

Create write lock on PutObject and CopyObject when on multi-pool setup.
Use the same lock as NewMultipartUpload so all creation calls share the same lock.
This feature also changes the default port where
the browser is running, now the port has moved
to 9001 and it can be configured with
```
--console-address ":9001"
```
When no results are sent `result.end` is never sent, so the list becomes hot until the list is full.
Break immediately when channel is closed.
Fixes#12518
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.
