This change adds a consistent nonce to ensure
that multipart uploads are deterministic on a
per-part basis.
Thanks to @klauspost for the work here minio/sio@3cd3734
locks handed by different pools would become non-compete for
multi-object delete request, this is wrong for obvious
reasons.
New locking implementation and revamp will rewrite multi-object
lock anyway, this is a workaround for now.
Currently, the bucket events and replication targets are only reloaded
with buckets that failed to load during the first cluster startup,
which is wrong because if one bucket change was done in one node but
that node was not able to notify other nodes; the other nodes will
reload the bucket metadata config but fails to set the events and bucket
targets in the memory.
when a hung drive is hot-unplugged, the server might go
into a loop where the previous `format.json` is somehow
still accessible to the process, we try to re-init() drives,
but that seems to cause a previous goroutine to hang around
since it is not canceled away when the drive is closed.
Bonus: add deadline for immediate purge routine, to unblock
it if the drive is blocking mutations.
if a user policy is found, avoid reading from the drives
for missing group mappings, group mappings are not mandatory
and conditional.
This PR restores the older behavior while making sure that
if a direct user policy is not found, we would still attempt
to load from the group from the drives.
This commit simplifies and optimizes the decryption of large (multipart)
objects. This PR does two things:
- Re-write the init logic for the decryption reader
- Reduce the number of OEK decryptions
Before, the init logic copied some SSE HTTP request headers to
parse them later. This is simplified to parsing them right away. This
removes some fields from the decryption reader struct.
Further, the decryption reader decrypted the OEK using the client-provided
key (SSE-C) or the KMS (SSE-S3 / SSE-KMS) for each part. This is redundant
since the OEK is the same for all parts. In particular, a KMS call might be a
network request. Now, the OEK is decrypted once for the entire multipart object.
This should improve latency when reading encrypted multipart objects
and reduce requests to the KMS.

Use Walk(), which is a recursive listing with versioning, to check if
the bucket has some objects before being removed. This is beneficial
because the bucket can contain multiple dangling objects in multiple
drives.
Also, this will prevent a bug where a bucket is deleted in a deployment
that has many erasure sets but the bucket contains one or few objects
not spread to enough erasure sets.
Currently, retry healing of a new drive healing does not reset
HealedBuckets means that the next healing retry will skip those
buckets. The commit will fix this behavior.
Also, the skipped objects counter will include objects uploaded
that are uploaded after the healing is started.
sftp sends local requests to the S3 port while passing the session token
header when the account corresponds to a service account. However, this
is not permitted and will throw an error: "The security token included in the
request is invalid"
This commit will avoid passing the session token to the upper layer that
initializes MinIO client to avoid this error.
Sometimes, we need historical information in .healing.bin, such as the
number of expired objects that the healing avoids to heal and that can
create drive usage disparency in the same erasure set. For that reason,
this commit will not remove .healing.bin anymore and it will have a new
field called Finished so we know healing is finished in that drive.
Services are unfrozen before `initBackgroundReplication` is finished. This means that
the globalReplicationStats write is racy. Switch to an atomic pointer.
Provide the `ReplicationPool` with the stats, so it doesn't have to be grabbed
from the atomic pointer on every use.
All other loads and checks are nil, and calls return empty values when stats
still haven't been initialized.
* Allow a maximum of 10 seconds to start profiling operations.
* Download up to 16 profiles concurrently, but only allow 10 seconds for
each (does not include write time).
* Add cluster info as the first operation.
* Ignore remote download errors.
* Stop remote profiles if the request is terminated.
If the site replication is enabled and the code tries to extract jwt
claims while the site replication service account credentials are still
not loaded yet, the code will enter an infinite loop, causing in a
high CPU usage.
Another possibility of the infinite loop is having some service accounts
created by an old deployment version where the service account JWT was
signed by the root credentials, but not anymore.
This commit will remove the possibility of the infinite loop in the code
and add root credential fallback to extract claims from old service
accounts.
move away from map[string]interface{} to map[string]string
to simplify the audit, and also provide concise information.
avoids large allocations under load(), reduces the amount
of audit information generated, as the current implementation
was a bit free-form. instead all datastructures must be
flattened.
Previously, we checked if we had a quorum on the DataDir value.
We are removing this check, which allows reading objects with different
DataDir values in a few drives (due to a rebalance-stop race bug)
provided their eTags or ModTimes match.
Since a lot of operations load from storage, do remote calls, add a 10 second timeout to each operation.
This should make `mc admin info` return values even under extreme conditions.
