time.Format() is not necessary prematurely for JSON
marshalling, since JSON marshalling indeed defaults
to RFC3339Nano.
This also ensures the 'time' is remembered until its
logged and it is the same time when the 'caller'
invoked 'log' functions.
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.
Return as soon as an AND fails and whenever an OR succeeds. Faster and more flexible.
For example makes `select * from S3object where _2 != '' AND _2 > 1` able to operate on empty fields.
Followup to #13900
- 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
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.
- 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.
This unit allows users to limit the maximum number of noncurrent
versions of an object.

- Go might reset the internal http.ResponseWriter() to `nil`
after Write() failure if the go-routine has returned, do not
flush() such scenarios and avoid spurious flushes() as
returning handlers always flush.
- fix some racy tests with the console
- avoid ticker leaks in certain situations
This feature is useful in situations when console is exposed
over multiple intranent or internet entities when users are
connecting over local IP v/s going through load balancer.

Borrowed idea from Go's usage of this
optimization for ReadFrom() on client
side, we should re-use the 32k buffers
io.Copy() allocates for generic copy
from a reader to writer.
the performance increase for reads for
really tiny objects is at this range

Preemptively disable AVX512 until https://github.com/golang/go/issues/49233 has been resolved.
This potentially affects reedsolomon, simdjson, sha256-simd, md5-simd packages.
Init order requires a separate package since main itself is initialized last, but imports are initialized in the order they are imported from main (confirmed).
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.
various situations where the client is retrying the request
server going through shutdown might incorrectly send 403
which is a non-retriable error, this PR allows for clients

additionally optimize for IP only setups, avoid doing

it would seem like using `bufio.Scan()` is very

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.
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.
- 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.
json.Unmarshal expects a pointer receiver, otherwise
kms.Context unmarshal fails with lack of pointer receiver,
this becomes complicated due to type aliasing over
map[string]string - fix it properly.
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.

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.

Use a single allocation for reading the file, not the growing buffer of `io.ReadAll`.
Reuse the write buffer if we can when writing metadata in RenameData.
A multi resources lock is a single lock UID with multiple associated
resources. This is created for example by multi objects delete
operation. This commit changes the behavior of Refresh() to iterate over
all locks having the same UID and refresh them.
Bonus: Fix showing top locks for multi delete objects
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.
- remove sourceCh usage from healing

- use read locks to lookup globalHealConfig
- fix healing resolver to pick candidates quickly

unexpectedly skipping.
healObject() should be non-blocking to ensure
that scanner is not blocked for a long time,
this adversely affects performance of the scanner

subsequently.
This PR allows for a non-blocking behavior for
healing, dropping operations that cannot be queued
anymore.
When reading `TrafficMeter` values, there was a value receiver.
This means that receivers are copied unsafely when invoked.
Fixes race seen with `-race` build.
This ensures that the deprecation warning is shown when the setting is actually
used in a configuration - instead of showing up whenever LDAP is enabled.
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.
Traffic metering was not protected against concurrent updates.
