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.
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.
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.
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"
A state is updated with a delete marker, which does not have parity or
data blocks defined, which can cause the integer divide by zero panics.
This commit fixes to avoid panics.
