- re-use net/url parsed value for http.Request{}

"consoleAdmin" was used as the policy for root derived accounts, but this
lead to unexpected bugs when an administrator modified the consoleAdmin
policy
This change avoids evaluating a policy for root derived accounts as by
default no policy is mapped to the root user. If a session policy is
attached to a root derived account, it will be evaluated as expected.
This PR changes the handling of bucket deletes for site
replicated setups to hold on to deleted bucket state until
it syncs to all the clusters participating in site replication.
Currently, if one server in a distributed setup fails to upgrade
due to any reasons, it is not possible to upgrade again unless
nodes are restarted.
To fix this, split the upgrade process into two steps :
- download the new binary on all servers
- If successful, overwrite the old binary with the new one
This commit replaces `ioutil.TempDir` with `t.TempDir` in tests. The
directory created by `t.TempDir` is automatically removed when the test
and all its subtests complete.
Prior to this commit, temporary directory created using `ioutil.TempDir`
needs to be removed manually by calling `os.RemoveAll`, which is omitted
in some tests. The error handling boilerplate e.g.
defer func() {
if err := os.RemoveAll(dir); err != nil {
t.Fatal(err)
}
}
is also tedious, but `t.TempDir` handles this for us nicely.

Add cluster info to inspect and profiling archive.
In addition to the existing data generation for both inspect and profiling,
cluster.info file is added. This latter contains some info of the cluster.
The generation of cluster.info is is done as the last step and it can fail
if it exceed 10 seconds.
a/b/c/d/ where `a/b/c/` exists results in additional syscalls
such as an Lstat() call to verify if the `a/b/c/` exists
and its a directory.
We do not need to do this on MinIO since the parent prefixes
if exist, we can simply return success without spending
additional syscalls.
Also this implementation attempts to simply use Access() calls
to avoid os.Stat() calls since the latter does memory allocation
for things we do not need to use.
Access() is simpler since we have a predictable structure on
the backend and we know exactly how our path structures are.
A huge number of goroutines would build up from various monitors
When creating test filesystems provide a context so they can shut down when no longer needed.
Do completely independent multipart uploads.
In distributed mode, a lock was held to merge each multipart
upload as it was added. This lock was highly contested and
retries are expensive (timewise) in distributed mode.
Instead, each part adds its metadata information uniquely.
This eliminates the per object lock required for each to merge.
The metadata is read back and merged by "CompleteMultipartUpload"
without locks when constructing final object.

Uploading a part object can leave an inconsistent state inside
.minio.sys/multipart where data are uploaded but xl.meta is not
committed yet.
Do not list upload-ids that have this state in the multipart listing.
Add up to 256 bytes of padding for compressed+encrypted files.
This will obscure the obvious cases of extremely compressible content
and leave a similar output size for a very wide variety of inputs.
This does *not* mean the compression ratio doesn't leak information
about the content, but the outcome space is much smaller,
so often *less* information is leaked.
Make bucket requests sent after decommissioning is started are not
created in a suspended pool. Therefore listing buckets should avoid
suspended pools as well.
Rename Trigger -> Event to be a more appropriate
name for the audit event.
Bonus: fixes a bug in AddMRFWorker() it did not
cancel the waitgroup, leading to waitgroup leaks.
There is no point in compressing very small files.
Typically the effective size on disk will be the same due to disk blocks.
So don't waste resources on extremely small files.
We don't check on multipart. 1) because we don't know and 2) this is very likely a big object anyway.
This commit adds a minimal set of KMS-related metrics:

# TYPE minio_cluster_kms_online gauge

# HELP minio_cluster_kms_request_error Number of KMS requests that failed with a well-defined error
# TYPE minio_cluster_kms_request_error counter

# HELP minio_cluster_kms_request_success Number of KMS requests that succeeded
# TYPE minio_cluster_kms_request_success counter
minio_cluster_kms_request_success{server="127.0.0.1:9000"} 348031

Currently, we report whether the KMS is available and how many requests
succeeded/failed. However, KES exposes much more metrics that can be
exposed if necessary. See: https://pkg.go.dev/github.com/minio/kes#Metric

If more than 1M folders (objects or prefixes) are found at the top level in a bucket allow it to be compacted.
While very suboptimal structure we should limit memory usage at some point.
GetDiskInfo() uses timedValue to cache the disk info for one second.
timedValue behavior was recently changed to return an old cached value
when calculating a new value returns an error.
When a mount point is empty, GetDiskInfo() will return errUnformattedDisk,
timedValue will return cached disk info with unexpected IsRootDisk value,
e.g. false if the mount point belongs to a root disk. Therefore, the mount
point will be considered a valid disk and will be formatted as well.
This commit will also add more defensive code when marking root disks:
always mark a disk offline for any GetDiskInfo() error except
errUnformattedDisk. The server will try anyway to reconnect to those
disks every 10 seconds.
it is not safe to pass around sync.Map
through pointers, as it may be concurrently
updated by different callers.
this PR simplifies by avoiding sync.Map
altogether, we do not need sync.Map
to keep object->erasureMap association.

The current code uses approximation using a ratio. The approximation
can skew if we have multiple pools with different disk capacities.
Replace the algorithm with a simpler one which counts data
disks and ignore parity disks.
fix: allow certain mutation on objects during decommission
currently by mistake deletion of objects was skipped,
if the object resided on the pool being decommissioned.
delete's are okay to be allowed since decommission is
designed to run on a cluster with active I/O.
Small uploads spend a significant amount of time (~5%) fetching disk info metrics. Also maps are allocated for each call.
Add a 100ms cache to disk metrics.
versioned buckets were not creating the delete markers
present in the versioned stack of an object, this essentially
would stop decommission to succeed.
This PR fixes creating such delete markers properly during
a decommissioning process, adds tests as well.
Current code incorrectly passed the
config asset object name while decommissioning,
make sure that we pass the right object name
to be hashed on the newer set of pools.
This PR fixes situations after a successful
decommission, the users and policies might go
missing due to wrong hashed set.
also use designated names for internal
calls
- storageREST calls are storageR
- lockREST calls are lockR
- peerREST calls are just peer
Named in this fashion to facilitate wildcard matches
by having prefixes of the same name.
Additionally, also enable funcNames for generic handlers
that return errors, currently we disable '<unknown>'
In a replicated setup, when an object is updated in one cluster but
still waiting to be replicated to the other cluster, GET requests with
if-match, and range headers will likely fail. It is better to proxy
requests instead.
Also, this commit avoids printing verbose logs about precondition &
range errors.
fix: change timedvalue to return previous cached value
caller can interpret the underlying error and decide
accordingly, places where we do not interpret the
errors upon timedValue.Get() - we should simply use
the previously cached value instead of returning "empty".
Bonus: remove some unused code
Add a generic handler that adds a new tracing context to the request if
tracing is enabled. Other handlers are free to modify the tracing
context to update information on the fly, such as, func name, enable
body logging etc..
With this commit, requests like this
```
curl -H "Host: ::1:3000" http://localhost:9000/
```
will be traced as well.
Directories markers are not healed when healing a new fresh disk. A
a proper fix would be moving object names encoding/decoding to erasure

Bonus changes:
- re-use transport for bucket replication clients, also site replication clients.
- use 32KiB buffer for all read and writes at transport layer seems to help
TLS read connections.
- Do not have 'MaxConnsPerHost' this is problematic to be used with net/http
connection pooling 'MaxIdleConnsPerHost' is enough.
- Always reformat all disks when a new disk is detected, this will
ensure new uploads to be written in new fresh disks
- Always heal all buckets first when an erasure set started to be healed
- Use a lock to prevent two disks belonging to different nodes but in
the same erasure set to be healed in parallel
- Heal different sets in parallel
Bonus:
- Avoid logging errUnformattedDisk when a new fresh disk is inserted but
not detected by healing mechanism yet (10 seconds lag)
site replication errors were printed at
various random locations, repeatedly - this
PR attempts to remove double logging and
capture all of them at a common place.
This PR also enhances the code to show
partial success and errors as well.
`mc admin heal -r <alias>` in a multi setup pools returns incorrectly
grey objects. The reason is that erasure-server-pools.HealObject() runs
HealObject in all pools and returns the result of the first nil
error. However, in the lower erasureObject level, HealObject() returns
nil if an object does not exist + missing error in each disk of the object
in that pool, therefore confusing mc.
Make erasureObject.HealObject() to return not found error in the lower
level, so at least erasureServerPools will know what pools to ignore.
`config.ResolveConfigParam` returns the value of a configuration for any
subsystem based on checking env, config store, and default value. Also returns info
about which config source returned the value.
This is useful to return info about config params overridden via env in the user
APIs. Currently implemented only for OpenID subsystem, but will be extended for
others subsequently.
If sending a white space during a long S3 handler call fails,
the whitespace goroutine forgets to return a result to the caller.
Therefore, the complete multipart handler will be blocked.
Remember to send the header written result to the caller
or/and close the channel.
- currently subnet health check was freezing and calling
locks at multiple locations, avoid them.
- throw errors if first attempt itself fails with no results
Erasure SD DeleteObjects() is only inheriting bucket versioning status
from the handler layer.
Add the missing versioning prefix evaluation for each object that will
deleted.
PR #15052 caused a regression, add the missing metrics back.
Bonus:
- internode information should be only for distributed setups
- update the dashboard to include 4xx and 5xx error panels.
this allows for customers to use `mc admin service restart`
directly even when performing RPM, DEB upgrades. Upon such 'restart'
after upgrade MinIO will re-read the /etc/default/minio for any
newer environment variables.
As long as `MINIO_CONFIG_ENV_FILE=/etc/default/minio` is set, this
is honored.
Currently minio_s3_requests_errors_total covers 4xx and
5xx S3 responses which can be confusing when s3 applications
sent a lot of HEAD requests with obvious 404 responses or
when the replication is enabled.
Add
- minio_s3_requests_4xx_errors_total
- minio_s3_requests_5xx_errors_total
to help users monitor 4xx and 5xx HTTP status codes separately.
peerOnlineCounter was making NxN calls to many peers, this
can be really long and tedious if there are random servers
that are going down.
Instead we should calculate online peers from the point of
view of "self" and return those online and offline appropriately
by performing a healthcheck.
* Add periodic callhome functionality
Periodically (every 24hrs by default), fetch callhome information and
upload it to SUBNET.
New config keys under the `callhome` subsystem:
enable - Set to `on` for enabling callhome. Default `off`
frequency - Interval between callhome cycles. Default `24h`
* Improvements based on review comments
- Update `enableCallhome` safely
- Rename pctx to ctx
- Block during execution of callhome
- Store parsed proxy URL in global subnet config
- Store callhome URL(s) in constants
- Use existing global transport
- Pass auth token to subnetPostReq
- Use `config.EnableOn` instead of `"on"`
* Use atomic package instead of lock
* Use uber atomic package
* Use `Cancel` instead of `cancel`

PR #15041 fixed replicating 'null' version however
due to a regression from #14994 caused the target
versions for these 'null' versioned objects to have
different 'versions', this may cause confusion with
bi-directional replication and cause double replication.
This PR fixes this properly by making sure we replicate
the correct versions on the objects.
mergeEntryChannels has the potential to perpetually
wait on the results channel, context might be closed
and we did not honor the caller context canceling.
The S3 service can be frozen indefinitely if a client or mc asks for object
perf API but quits early or has some networking issues. The reason is
that partialWrite() can block indefinitely.
This commit makes partialWrite() listens to context cancellation as well. It
also renames deadlinedCtx to healthCtx since it covers handler context
cancellation and not only not only the speedtest deadline.
In a streaming response, the client knows the size of a streamed
message but never checks the message size. Add the check to error
out if the response message is truncated.
Indexed streams would be decoded by the legacy loader if there
was an error loading it. Return an error when the stream is indexed
and it cannot be loaded.
Fixes "unknown minor metadata version" on corrupted xl.meta files and
returns an actual error.
We need to make sure if we cannot read bucket metadata
for some reason, and bucket metadata is not missing and
returning corrupted information we should panic such
handlers to disallow I/O to protect the overall state
on the system.
In-case of such corruption we have a mechanism now
to force recreate the metadata on the bucket, using
`x-minio-force-create` header with `PUT /bucket` API
call.
Additionally fix the versioning config updated state
to be set properly for the site replication healing
to trigger correctly.
readAllXL would return inlined data for outdated disks
causing "read" to return incorrect content to the client,
this PR fixes this behavior by making sure we skip such
outdated disks appropriately based on the latest ModTime
on the disk.
Main motivation is move towards a common backend format
for all different types of modes in MinIO, allowing for
a simpler code and predictable behavior across all features.
This PR also brings features such as versioning, replication,
transitioning to single drive setups.
Following code can reproduce an unending go-routine buildup,
while keeping connections established due to lack of client
not closing the connections.

Without this PR all MinIO deployments can be put into
denial of service attacks, causing entire service to be
unavailable.
We bring in two timeouts at this stage to control such
go-routine build ups, new change
- IdleTimeout (to kill off idle connections)
- ReadHeaderTimeout (to kill off connections that are too slow)
This new change also brings two hidden options to make any
additional relevant changes if desired in some setups.
It would seem like the PR #11623 had chewed more
than it wanted to, non-fips build shouldn't really
be forced to use slower crypto/sha256 even for
presumed "non-performance" codepaths. In MinIO
there are really no "non-performance" codepaths.
This assumption seems to have had an adverse
effect in certain areas of CPU usage.
This PR ensures that we stick to sha256-simd
on all non-FIPS builds, our most common build
to ensure we get the best out of the CPU at
any given point in time.
- Adds an STS API `AssumeRoleWithCustomToken` that can be used to
authenticate via the Id. Mgmt. Plugin.
- Adds a sample identity manager plugin implementation
- Add doc for plugin and STS API
- Add an example program using go SDK for AssumeRoleWithCustomToken
this PR also fixes a situation where incorrect
partsMetadata slice was used where fi.Data was
re-used from a single drive causing duplication
of the shards across all drives.
This happens for situations where shouldHeal()
returns true for all drives > parityBlocks.
To avoid this we should never attempt to heal on all
drives > parityBlocks, unless we are doing metadata
migration from xl.json -> xl.meta
If one or more pools reach 85% usage in a set, we will only
use pools that have more free space.
In case all pools are above 85% we allow all of them to be used
with the regular distribution.
When a server pool with a different number of sets is added they are
not compensated when choosing a destination pool for new objects.
This leads to the unbalanced placement of objects with smaller pools
getting a bigger number of objects since we only compare the destination
sets directly.
This change will compensate for differences in set sizes when choosing
the destination pool.
Different set sizes are already compensated by fewer disks.
updating metadata with CopyObject on a versioned bucket
causes the latest version to be not readable, this PR fixes
this properly by handling the inline data bug fix introduced
in PR #14780.
This bug affects only inlined data.
* Do not use inline data size in xl.meta quorum calculation
Data shards of one object can different inline/not-inline decision
in multiple disks. This happens with outdated disks when inline
decision changes. For example, enabling bucket versioning configuration
will change the small file threshold.
When the parity of an object becomes low, GET object can return 503
because it is not unable to calculate the xl.meta quorum, just because
some xl.meta has inline data and other are not.
So this commit will be disable taking the size of the inline data into
consideration when calculating the xl.meta quorum.
* Add tests for simulatenous inline/notinline object

current implementation relied on recursively calling one bucket
at a time across all peers, this would be very slow and chatty
when there are 100's of buckets which would mean 100*peerCount
amount of network operations.
This PR attempts to reduce this entire call into `peerCount`
amount of network calls only. This functionality addresses also a
concern where the Prometheus metrics would significantly slow
down when one of the peers is offline.

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

this PR fixes all the usage comprehensively
anything that is stuck on the disk today can cause latency
spikes for all incoming S3 I/O, we need to have this
de-coupled so that we can make sure that latency in loading
credentials are not reflected back to the S3 API calls.
The approach this PR takes is by checking if the calls were
updated just in case when the IAM load was in progress,
so that we can use merge instead of "replacement" to avoid
missing state.
The test expects from DeleteFile to return errDiskNotFound when the disk
is not available. It calls os.RemoveAll() to remove one disk after XL storage
initialization. However, this latter contains some goroutines which can
race with os.RemoveAll() and then the test fails sporadically with
returning random errors.
The commit will tweak the initialization routine of the XL storage to
only run deletion of temporary and metacache data in the background,
so TestXLStorageDeleteFile won't fail anymore.
currently, we allowed buckets to be listed from the
API call if and when the user has ListObject()
permission at the global level, this is okay to be
extended to GetBucketLocation() as well since
GetBucketLocation() is a "read" call and allowing "reads"
on a bucket has an implicit assumption that ListBuckets()
should be allowed.
This makes discoverability of access for read-only users
becomes easier or users with specific restrictions on their
policies.
This PR simplifies few things by splitting
the locks between audit, logger targets to

- This change renames the OPA integration as Access Management Plugin - there is
nothing specific to OPA in the integration, it is just a webhook.
- OPA configuration is automatically migrated to Access Management Plugin and
OPA specific configuration is marked as deprecated.

In case of multi-pools setup, GetObjectNInfo returns a GetObjectReader
but it unlocks the read lock when quitting GetObjectNInfo. This should
not happen, unlock should only happen when GetObjectReader is closed.
- do not need to restrict prefix exclusions that do not

- multiple delete objects was incorrectly creating a

creating a proper versioned delete marker.
- do not suspend paths on the excluded prefixes during
delete operations to avoid creating `null` delete markers,
honor suspension of versioning only at bucket level for
delete markers.
PR #14828 introduced prefix-level exclusion of versioning
and replication - however our site replication implementation
since it defaults versioning on all buckets did not allow
changing versioning configuration once the bucket was created.
This PR changes this and ensures that such changes are honored
and also propagated/healed across sites appropriately.
Spark/Hadoop workloads which use Hadoop MR
Committer v1/v2 algorithm upload objects to a
temporary prefix in a bucket. These objects are
'renamed' to a different prefix on Job commit.
Object storage admins are forced to configure
separate ILM policies to expire these objects
and their versions to reclaim space.
Our solution:
This can be avoided by simply marking objects
under these prefixes to be excluded from versioning,
as shown below. Consequently, these objects are
excluded from replication, and don't require ILM
policies to prune unnecessary versions.
- MinIO Extension to Bucket Version Configuration
```xml
<VersioningConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<Status>Enabled</Status>
<ExcludeFolders>true</ExcludeFolders>
<ExcludedPrefixes>
<Prefix>app1-jobs/*/_temporary/</Prefix>
</ExcludedPrefixes>
<ExcludedPrefixes>
<Prefix>app2-jobs/*/__magic/</Prefix>
</ExcludedPrefixes>
<!-- .. up to 10 prefixes in all -->
</VersioningConfiguration>
```
Note: `ExcludeFolders` excludes all folders in a bucket
from versioning. This is required to prevent the parent
folders from accumulating delete markers, especially
those which are shared across spark workloads
spanning projects/teams.
- To enable version exclusion on a list of prefixes
```
mc version enable --excluded-prefixes "app1-jobs/*/_temporary/,app2-jobs/*/_magic," --exclude-prefix-marker myminio/test

happen when a new deployment is brought in place of a site that
is lost/destroyed and needs to delink old deployment from site
replication.
console logging peer API was broken as it would
timeout after 15minutes, this never really worked

do not modify opts.UserDefined after object-handler

When a decommission task is successfully completed, failed, or canceled,
this commit allows restarting the decommission again. Restarting is not
allowed when there is an ongoing decommission task.
this PR introduces a few changes such as
- sessionPolicyName is not reused in an extracted manner
to apply policies for incoming authenticated calls,
instead uses a different key to designate this
information for the callers.
- this differentiation is needed to ensure that service
account updates do not accidentally store JSON representation
instead of base64 equivalent on the disk.
- relax requirements for Deleting a service account, allow
deleting a service account that might be unreadable, i.e
a situation where the user might have removed session policy
which now carries a JSON representation, making it unparsable.
- introduce some constants to reuse instead of strings.

space characters at the beginning or at the end can lead to
confusion under various UI elements in differentiating the
actual name of "policy, user or group" - to avoid this behavior
this PR onwards we shall reject such inputs for newer entries.
existing saved entries will behave as is and are going to be
operable until they are removed/renamed to something more
meaningful.
- When using multiple providers, claim-based providers are not allowed. All
providers must use role policies.
- Update markdown config to allow `details` HTML element
this is allowed as long as order is preserved as is
on an existing setup, the new command line is updated
in `pool.bin` to facilitate future decommission's on
these pools.
introduce x-minio-force-create environment variable
to force create a bucket and its metadata as required,
it is useful in some situations when bucket metadata
needs recovery.
improvements in this PR include
- decommission objects that have __XLDIR__ suffix
- decommission objects that have `null` version on
a versioned bucket.
- make sure to look for any "decom" failures to ensure
that we do not wrong conclude decom as complete without
all files getting copied over.
- break out eagerly upon first error for objects with
multiple versions, leave the object as is for support
debugging and analysis.
heal bucket metadata and IAM entries for
sites participating in site replication from
the site with the most updated entry.

The site replication status call was using a loop iteration variable sent
directly into go-routines instead of being passed as an argument. As the
variable is being updated in the loop, previously launched go routines do not
necessarily use the value at the time they were launched.
This PR fixes two issues
- The first fix is a regression from #14555, the fix itself in #14555
is correct but the interpretation of that information by the
object layer code for "replication" was not correct. This PR
tries to fix this situation by making sure the "Delete" replication
works as expected when "VersionPurgeStatus" is already set.
Without this fix, there is a DELETE marker created incorrectly on
the source where the "DELETE" was triggered.
- The second fix is perhaps an older problem started since we inlined-data
on the disk for small objects, CopyObject() incorrectly inline's
a non-inlined data. This is due to the fact that we have code where
we read the `part.1` under certain conditions where the size of the
`part.1` is less than the specific "threshold".
This eventually causes problems when we are "deleting" the data that
is only inlined, which means dataDir is ignored leaving such
dataDir on the disk, that looks like an inconsistent content on
the namespace.
fixes#14767
It is wasteful to allow parallel upgrades of MinIO server. This also generates
weird error invoked by selfupdate module when it happens such as:
'rename /opt/bin/.minio.old /opt/bin/..minio.old.old'
currently filterPefix was never used and set
that would filter out entries when needed
when `prefix` doesn't end with `/` - this
often leads to objects getting Walked(), Healed()
that were never requested by the caller.
without this wait there is a potential for some objects
that are in actively being decommissioned would cancel,
however the decommission status might wrongly conclude
this as "Complete".
To avoid this make sure to add waitgroups on the parallel
workers, allowing parallel copies to complete fully before
we return.
In previous releases, mc admin user list would return the list of users
that have policies mapped in IAM database. However, this was removed but
this commit will bring it back until we revamp this.
- This change switches to a new parquet library
- SelectObjectContent now takes a single lock at the beginning and holds it
during the operation. Previously the operation took a lock every time the
parquet library performed a Seek on the underlying object stream.
- Add basic support for LogicalType annotations for timestamps.
Execute the object, drive and net speedtests as part of the healthinfo
(if requested by the client), and include their result in the response.
The options for the speedtests have been picked from the default values
used by `mc support perf` command.
This commit improves the listing of encrypted objects:
- Use `etag.Format` and `etag.Decrypt`
- Detect SSE-S3 single-part objects in a single iteration
- Fix batch size to `250`
- Pass request context to `DecryptAll` to not waste resources
when a client cancels the operation.
