configs from 2020 server throws an
error due to deprecation of the keys
however an attempt is made to parse
them, we should have chosen existing
defaults - this PR fixes that.
Fix drive rotational calculation status
If a MinIO drive path is mounted to a partition and not a real disk,
getting the rotational status would fail because Linux does not expose
that status to partition; In other words,
/sys/block/drive-partition-name/queue/rotational does not exist;
To fix the issue, the code will search for the rotational status of the
disk that hosts the partition, and this can be calculated from the
real path of /sys/class/block/<drive-partition-name>
Keys are helpful to ensure the strict ordering of messages, however currently the
code uses a random request id for every log, hence using the request-id
as a Kafka key is not serve any purpose;
This commit removes the usage of the key, to also fix the audit issue from
internal subsystem that does not have a request ID.
This commit updates the minio/kes-go dependency
to v0.2.0 and updates the existing code to work
with the new KES APIs.
The `SetPolicy` handler got removed since it
may not get implemented by KES at all and could
not have been used in the past since stateless KES
is read-only w.r.t. policies and identities.

Two fields in lifecycles made GOB encoding consistently fail with `gob: type lifecycle.Prefix has no exported fields`.
This meant that in distributed systems listings would never be able to continue and would restart on every call.
Fix issues and be sure to log these errors at least once per bucket. We may see some connectivity errors here, but we shouldn't hide them.
Bonus:
- avoid calling DiskInfo() calls when missing blocks
instead heal the object using MRF operation.
- change the max_sleep to 250ms beyond that we will
not stop healing.
Send() is synchronous and can affect the latency of S3 requests when the
logger buffer is full.
Avoid checking if the HTTP target is online or not and increase the
workers anyway since the buffer is already full.
Also, avoid logs flooding when the audit target is down.
slower drives get knocked off because they are too slow via
active monitoring, we do not need to block calls arbitrarily.
Serializing adds latencies for already slow calls, remove
it for SSDs/NVMEs
Also, add a selection with context when writing to `out <-`
channel, to avoid any potential blocks.
Now it would list details of all KMS instances with additional
attributes `endpoint` and `version`. In the case of k8s-based
deployment the list would consist of a single entry.

Also shutdown poll add jitter, to verify if the shutdown
sequence can finish before 500ms, this reduces the overall
time taken during "restart" of the service.
Provides speedup for `mc admin service restart` during
active I/O, also ensures that systemd doesn't treat the
returned 'error' as a failure, certain configurations in
systemd can cause it to 'auto-restart' the process by-itself
which can interfere with `mc admin service restart`.
It can be observed how now restarting the service is
much snappier.
DNS refresh() in-case of MinIO can safely re-use
the previous values on bare-metal setups, since
bare-metal arrangements do not change DNS in any
manner commonly.
This PR simplifies that, we only ever need DNS caching
on bare-metal setups.
- On containerized setups do not enable DNS
caching at all, as it may have adverse effects on
the overall effectiveness of k8s DNS systems.
k8s DNS systems are dynamic and expect applications
to avoid managing DNS caching themselves, instead
provide a cleaner container native caching
implementations that must be used.
- update IsDocker() detection, including podman runtime
- move to minio/dnscache fork for a simpler package

This change adds a `Secret` property to `HelpKV` to identify secrets
like passwords and auth tokens that should not be revealed by the server
in its configuration fetching APIs. Configuration reporting APIs now do
not return secrets.
With the current asynchronous behaviour in sending notification events
to the targets, we can't provide guaranteed delivery as the systems
might go for restarts.
For such event-driven use-cases, we can provide an option to enable
synchronous events where the APIs wait until the event is successfully
sent or persisted.
This commit adds 'MINIO_API_SYNC_EVENTS' env which when set to 'on'
will enable sending/persisting events to targets synchronously.
- lifecycle must return InvalidArgument for rule errors
- do not return `null` versionId in HTTP header
- reject mixed SSE uploads with correct error message
PUT calls cannot afford to have large latency build-ups due
to contentious usage.json, or worse letting them fail with
some unexpected error, this can happen when this file is
concurrently being updated via scanner or it is being
healed during a disk replacement heal.
However, these are fairly quick in theory, stressed clusters
can quickly show visible latency this can add up leading to
invalid errors returned during PUT.
It is perhaps okay for us to relax this error return requirement
instead, make sure that we log that we are proceeding to take in
the requests while the quota is using an older value for the quota
enforcement. These things will reconcile themselves eventually,
via scanner making sure to overwrite the usage.json.
Bonus: make sure that storage-rest-client sets ExpectTimeouts to
be 'true', such that DiskInfo() call with contextTimeout does
not prematurely disconnect the servers leading to a longer
healthCheck, back-off routine. This can easily pile up while also
causing active callers to disconnect, leading to quorum loss.
DiskInfo is actively used in the PUT, Multipart call path for
upgrading parity when disks are down, it in-turn shouldn't cause
more disks to go down.
