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.

User doesn't need to remember and enter the server values,
rather they can select from the pre populated list.

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.
As total drives count, online vs offline are per node basis, its
corect to select node for which graphs need to be rendered.
Set prometheus scrape jobs to fetch metrics from all nodes. A sample
scrape job for node metrics could be as below
```

scheme: https
tls_config:
insecure_skip_verify: true
static_configs:

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.

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.
This commit changes how MinIO generates the object encryption key (OEK)
when encrypting an object using server-side encryption.
This change is fully backwards compatible. Now, MinIO generates
the OEK as following:
```
Nonce = RANDOM(32) // generate 256 bit random value
OEK = HMAC-SHA256(EK, Context || Nonce)
```
Before, the OEK was computed as following:
```
Nonce = RANDOM(32) // generate 256 bit random value
OEK = SHA256(EK || Nonce)
```
The new scheme does not technically fix a security issue but
uses a more familiar scheme. The only requirement for the
OEK generation function is that it produces a (pseudo)random value
for every pair (`EK`,`Nonce`) as long as no `EK`-`Nonce` combination
is repeated. This prevents a faulty PRNG from repeating or generating
a "bad" key.
The previous scheme guarantees that the `OEK` is a (pseudo)random
value given that no pair (`EK`,`Nonce`) repeats under the assumption
that SHA256 is indistinguable from a random oracle.
The new scheme guarantees that the `OEK` is a (pseudo)random value
given that no pair (`EK`, `Nonce`) repeats under the assumption that
SHA256's underlying compression function is a PRF/PRP.
While the later is a weaker assumption, and therefore, less likely
to be false, both are considered true. SHA256 is believed to be
indistinguable from a random oracle AND its compression function
is assumed to be a PRF/PRP.
As far as the OEK generating is concerned, the OS random number
generator is not required to be pseudo-random but just non-repeating.
Apart from being more compatible to standard definitions and
descriptions for how to generate crypto. keys, this change does not
have any impact of the actual security of the OEK key generation.
