This change uses the updated ldap library in minio/pkg (bumped
up to v3). A new config parameter is added for LDAP configuration to
specify extra user attributes to load from the LDAP server and to store
them as additional claims for the user.
A test is added in sts_handlers.go that shows how to access the LDAP
attributes as a claim.
This is in preparation for adding SSH pubkey authentication to MinIO's SFTP
integration.
Typically not all drives are connected, so we delay 3 minutes before resuming.
This greatly reduces risk of starting to list unconnected drives, or drives we risk being disconnected soon.
This delay is not applied when starting with an admin call.
This PR makes a feasible approach to handle all the scenarios
that we must face to avoid returning "panic."
Instead, we must return "errServerNotInitialized" when a
bucketMetadataSys.Get() is called, allowing the caller to
retry their operation and wait.
Bonus fix the way data-usage-cache stores the object.
Instead of storing usage-cache.bin with the bucket as
`.minio.sys/buckets`, the `buckets` must be relative
to the bucket `.minio.sys` as part of the object name.
Otherwise, there is no way to decommission entries at
`.minio.sys/buckets` and their final erasure set positions.
A bucket must never have a `/` in it. Adds code to read()
from existing data-usage.bin upon upgrade.
Create new code paths for multiple subsystems in the code. This will
make maintaing this easier later.
Also introduce bugLogIf() for errors that should not happen in the first
place.
When returning the status of a decommissioned pool, a pool with zero
time StartedTime will be considered an active pool, which is unexpected.
This commit will always ensure that a pool's canceled/failed/completed
status is returned.
there can be a sudden spike in tiny allocations,
due to too much auditing being done, also don't hang
on the
```
h.logCh <- entry
```
after initializing workers if you do not have a way to
dequeue for some reason.
Add a new function logger.Event() to send the log to Console and
http/kafka log webhooks. This will include some internal events such as
disk healing and rebalance/decommissioning
it is entirely possible that a rebalance process which was running
when it was asked to "stop" it failed to write its last statistics
to the disk.
After this a pool expansion can cause disruption and all S3 API
calls would fail at IsPoolRebalancing() function.
This PRs makes sure that we update rebalance.bin under such
conditions to avoid any runtime crashes.
With an odd number of drives per erasure set setup, the write/quorum is
the half + 1; however the decommissioning listing will still list those
objects and does not consider those as stale.
Fix it by using (N+1)/2 formula.

There is a fundamental race condition in `newErasureServerPools`, where setObjectLayer is
called before the poolMeta has been loaded/populated.
We add a placeholder value to this field but disable all saving of the value, so we don't risk
overwriting the value on disk. Once the value has been loaded or created, it is replaced with
the proper value, which will also be saved.
Also fixes various accesses of `poolMeta` that were done without locks.
We make the `poolMeta.IsSuspended` return false, even if we shouldn't risk out-of-bounds
reads anymore.
- remove targetClient for passing around via replicationObjectInfo{}
- remove cloing to object info unnecessarily
- remove objectInfo from replicationObjectInfo{} (only require necessary fields)
current decommission traces were missing for
- Skipped ILM expired versions
- Skipped single DELETE marked version
- A success or failure in decommissioning DELETE marker
- allow additional info to be shared in DecomStatus() API
A continuation of PR #17479 for rebalance behavior must
also match the decommission behavior.
Fixes bug where rebalance would ignore rebalancing object
versions after one of the version returned "ObjectNotFound"
while decommissioning it can so happen that the non-current
versions are all expired but there is a DEL marker as the
latest version.
For such objects, we should not decommission them instead
calculate the remaining versions and if the remaining versions
is one and that version is a DEL marker consider such
an object not to be scheduled for decommissioning.
