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.
The code was not properly deciding if a lock needs to be removed
when it doesn't have quorum anymore. After this commit, a lock will be
forcefully unlocked if nodes reporting they are not able to find a lock
internally breaks the quorum.
Simplify the code as well.

- 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).
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.
To enable this rule you need the following *ilm.json*
```

- 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
after this change.

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
when they retry an attempt to go to another healthy pod

load-balanced setup.
also simplify readerLocks to be just like

3DES is enabled by default in Golang, this commit will use

maybe many certs talking to common DNS endpoint it is
better to allow Dialer to choose appropriate public cert.
additionally optimize for IP only setups, avoid doing
unnecessary lookups if the Dial addr is an IP.
allow support for multiple listeners on same socket,
this is mainly meant for future purposes.
it would seem like using `bufio.Scan()` is very
slow for heavy concurrent I/O, ie. when r.Body

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

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

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.

This happens because of a change added where any sub-credential
with parentUser == rootCredential i.e (MINIO_ROOT_USER) will
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
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.
- Show notice when `MINIO_IDENTITY_LDAP_STS_EXPIRY` or the
corresponding to the configuration option is used at server startup.
- Once support is removed, the default will be fixed at 1 hour.
- Users may specify expiry directly in the STS API.
- Update docs and help message
- Adds example in ldap.go to configure expiry in STS API.
when TLS is configured using IPs directly
might interfere and not work properly when
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.
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.
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.
fixes#12661
Additional support for vendor-specific admin API
integrations for OpenID, to ensure validity of

Every 5minutes check for validity of credentials

auditLog should be attempted right before the

per function, this ensures that we only trigger
it once per function call.
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.
This feature also changes the default port where
