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.

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.
at scale customers might start with failed drives,
causing skew in the overall usage ratio per EC set.
make this configurable such that customers can turn
this off as needed depending on how comfortable they
are.
Cosmetic change, but breaks up a big code block and will make a goroutine
dumps of streams are more readable, so it is clearer what each goroutine is doing.
Currently, the code relies on object parity to decide whether it is a
delete marker or a regular object. In the case of a delete marker, the
return quorum is half of the disks in the erasure set. However, this
calculation must be corrected with objects with EC = 0, mainly
because EC is not a one-time fixed configuration.
Though all data are correct, the manifested symptom is a 503 with an
EC=0 object. This bug was manifested after we introduced the
fast Get Object feature that does not read all data from all disks in
case of inlined objects
Metrics v3 is mainly a reorganization of metrics into smaller groups of
metrics and the removal of internal aggregation of metrics received from
peer nodes in a MinIO cluster.
This change adds the endpoint `/minio/metrics/v3` as the top-level metrics
endpoint and under this, various sub-endpoints are implemented. These
are currently documented in `docs/metrics/v3.md`
The handler will serve metrics at any path
`/minio/metrics/v3/PATH`, as follows:
when PATH is a sub-endpoint listed above => serves the group of
metrics under that path; or when PATH is a (non-empty) parent
directory of the sub-endpoints listed above => serves metrics
from each child sub-endpoint of PATH. otherwise, returns a no
resource found error
All available metrics are listed in the `docs/metrics/v3.md`. More will
be added subsequently.
When an object qualifies for both tiering and expiration rules and is
past its expiration date, it should be expired without requiring to tier
it, even when tiering event occurs before expiration.
Merging same-object - multiple versions from different pools would not always result in correct ordering.
When merging keep inputs separate.

configure batch size to send audit/logger events
in batches instead of sending one event per connection.
this is mainly to optimize the number of requests
we make to webhook endpoint.
Currently, the progress of the batch job is saved in inside the job
request object, which is normally not supported by MinIO. Though there
is no apparent bug, it is better to fix this now.
Batch progress is saved in .minio.sys/batch-jobs/reports/

our PoolNumber calculation was costly,
while we already had this information per
endpoint, we needed to deduce it appropriately.
This PR addresses this by assigning PoolNumbers
field that carries all the pool numbers that
belong to a server.
properties.PoolNumber still carries a valid value
only when len(properties.PoolNumbers) == 1, otherwise
properties.PoolNumber is set to math.MaxInt (indicating
that this value is undefined) and then one must rely
on properties.PoolNumbers for server participation
in multiple pools.
addresses the issue originating from #11327
simplify audit webhook worker model
fixes couple of bugs like
- ping(ctx) was creating a logger without updating
number of workers leading to incorrect nWorkers
scaling, causing an additional worker that is not
tracked properly.
- h.logCh <- entry could potentially hang for when
the queue is full on heavily loaded systems.
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.
