Set object's modTime when being restored
restored here refers to making a temporary local copy in the hot tier
for a tiered object using the RestoreObject API
we have been using an LRU caching for internode
auth tokens, migrate to using a typed implementation
and also do not cache auth tokens when its an error.
This fixes a regression from #19358 which prevents policy mappings
created in the latest release from being displayed in policy entity
listing APIs.
This is due to the possibility that the base DNs in the LDAP config are
not in a normalized form and #19358 introduced normalized of mapping
keys (user DNs and group DNs). When listing, we check if the policy
mappings are on entities that parse as valid DNs that are descendants of
the base DNs in the config.
Test added that demonstrates a failure without this fix.
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.
This commit replaces the `KMS.Stat` API call with a
`KMS.GenerateKey` call. This approach is more reliable
since data key generation also works when the KMS backend
is unavailable (temp. offline), but KES has cached the
key. Ref: KES offline caching.
With this change, it is less likely that MinIO readiness
checks fail in cases where the KMS backend is offline.

Make sure to pass a nil pointer as a Transport to minio-go when the API config
is not initialized, this will make sure that we do not pass an interface
with a known type but a nil value.
This will also fix the update of the API remote_transport_deadline
configuration without requiring the cluster restart.
Use `ODirectPoolSmall` buffers for inline data in PutObject.
Add a separate call for inline data that will fetch a buffer for the inline data before unmarshal.
This fixes a bug where STS Accounts map accumulates accounts in memory
and never removes expired accounts and the STS Policy mappings were not
being refreshed.
The STS purge routine now runs with every IAM credentials load instead
of every 4th time.
The listing of IAM files is now cached on every IAM load operation to
prevent re-listing for STS accounts purging/reload.
Additionally this change makes each server pick a time for IAM loading
that is randomly distributed from a 10 minute interval - this is to
prevent server from thundering while performing the IAM load.
On average, IAM loading will happen between every 5-15min after the
previous IAM load operation completes.
If site replication enabled across sites, replicate the SSE-C
objects as well. These objects could be read from target sites
using the same client encryption keys.

Instead of relying on user input values, we use the DN value returned by
the LDAP server.
This handles cases like when a mapping is set on a DN value
`uid=svc.algorithm,OU=swengg,DC=min,DC=io` with a user input value (with
unicode variation) of `uid=svc﹒algorithm,OU=swengg,DC=min,DC=io`. The
LDAP server on lookup of this DN returns the normalized value where the
unicode dot character `SMALL FULL STOP` (in the user input), gets
replaced with regular full stop.
Bonus: remove persistent md5sum calculation, turn-off
sha256 as well. Instead we always enable crc32c which
is enough for payload verification also support for
trailing headers checksum.
Fix races in IAM cache
Fixes#19344
On the top level we only grab a read lock, but we write to the cache if we manage to fetch it.
a03dac41eb/cmd/iam-store.go (L446) is also flipped to what it should be AFAICT.
Change the internal cache structure to a concurrency safe implementation.
Bonus: Also switch grid implementation.
we must attempt to convert all errors at storage-rest-client
into StorageErr() regardless of what functionality is being
called in, this PR fixes this for multiple callers including
some internally used functions.
- old version was unable to retain messages during config reload
- old version could not go from memory to disk during reload
- new version can batch disk queue entries to single for to reduce I/O load
- error logging has been improved, previous version would miss certain errors.
- logic for spawning/despawning additional workers has been adjusted to trigger when half capacity is reached, instead of when the log queue becomes full.
- old version would json marshall x2 and unmarshal 1x for every log item. Now we only do marshal x1 and then we GetRaw from the store and send it without having to re-marshal.
panic seen due to premature closing of slow channel while listing is still sending or
list has already closed on the sender's side:

Object names of directory objects qualified for ExpiredObjectAllVersions
must be encoded appropriately before calling on deletePrefix on their
erasure set.
e.g., a directory object and regular objects with overlapping prefixes
could lead to the expiration of regular objects, which is not the
intention of ILM.
```
bucket/dir/ ---> directory object
bucket/dir/obj-1
```
When `bucket/dir/` qualifies for expiration, the current implementation would
remove regular objects under the prefix `bucket/dir/`, in this case,
`bucket/dir/obj-1`.
In handlers related to health diagnostics e.g. CPU, Network, Partitions,
etc, globalMinioHost was being passed as the addr, resulting in empty
value for the same in the health report.
Using globalLocalNodeName instead fixes the issue.
IAM loading is a lazy operation, allow these
fallbacks to be in place when we cannot find
in-memory state().
this allows us to honor the request even if pay
a small price for lookup and populating the data.
When objects have more versions than their ILM policy expects to retain
via NewerNoncurrentVersions, but they don't qualify for expiry due to
NoncurrentDays are configured in that rule.
In this case, applyNewerNoncurrentVersionsLimit method was enqueuing empty
tasks, which lead to a panic (panic: runtime error: index out of range [0] with
length 0) in newerNoncurrentTask.OpHash method, which assumes the task
to contain at least one version to expire.
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.
we were prematurely not writing 4k pages while we
could have due to the fact that most buffers would
be multiples of 4k upto some number and there shall
be some remainder.
We only need to write the remainder without O_DIRECT.
