endpoint, additionally add prometheus as part of
diagnostics canned policy.

This commit changes the config/IAM encryption
process. Instead of encrypting config data
(users, policies etc.) with the root credentials
MinIO now encrypts this data with a KMS - if configured.
Therefore, this PR moves the MinIO-KMS configuration (via
env. variables) to a "top-level" configuration.
The KMS configuration cannot be stored in the config file
since it is used to decrypt the config file in the first
place.
As a consequence, this commit also removes support for
Hashicorp Vault - which has been deprecated anyway.

* fix: pick valid FileInfo additionally based on dataDir
historically we have always relied on modTime
to be consistent and same, we can now add additional
reference to look for the same dataDir value.
A dataDir is the same for an object at a given point in
time for a given version, let's say a `null` version
is overwritten in quorum we do not by mistake pick
up the fileInfo's incorrectly.
* make sure to not preserve fi.Data

InfoServiceAccount admin API does not correctly calculate the policy for
a given service account in case if the policy is implied. Fix it.

avoid potential for duplicates under multi-pool
setup, additionally also make sure CompleteMultipart
is using a more optimal API for uploadID lookup
and never delete the object there is a potential
to create a delete marker during complete multipart.

This is an optimization by reducing one extra system call,
and many network operations. This reduction should increase
the performance for small file workloads.
When an error is reported it is ignored and zipping continues with the next object.
However, if there is an error it will write a response to `writeWebErrorResponse(w, err)`, but responses are still being built.
Fixes#12082
Bonus: Exclude common compressed image types.
Thanks to @Alevsk for noticing this nuanced behavior
change between releases from 03-04 to 03-20, make sure
that we handle the legacy path removal as well.
also make sure to close the channel on the producer
side, not in a separate go-routine, this can lead
to races between a writer and a closer.

This is an optimization to save IOPS. The replication
failures will be re-queued once more to re-attempt
replication. If it still does not succeed, the replication
status is set as `FAILED` and will be caught up on
scanner cycle.
For InfoServiceAccount API, calculating the policy before showing it to
the user was not correctly done (only UX issue, not a security issue)
This commit fixes it.
policy might have an associated mapping with an expired
user key, do not return an error during DeletePolicy
for such situations - proceed normally as its an
expected situation.
This commit introduces a new package `pkg/kms`.
It contains basic types and functions to interact
with various KMS implementations.
This commit also moves KMS-related code from `cmd/crypto`
to `pkg/kms`. Now, it is possible to implement a KMS-based
config data encryption in the `pkg/config` package.
This commit introduces a new package `pkg/fips`
that bundles functionality to handle and configure
cryptographic protocols in case of FIPS 140.
If it is compiled with `--tags=fips` it assumes
that a FIPS 140-2 cryptographic module is used
to implement all FIPS compliant cryptographic
primitives - like AES, SHA-256, ...
In "FIPS mode" it excludes all non-FIPS compliant
cryptographic primitives from the protocol parameters.
- Add 32-bit checksum (32 LSB part of xxhash64) of the serialized metadata.
This will ensure that we always reject corrupted metadata.
- Add automatic repair of inline data, so the data structure can be used.
If data was corrupted, we remove all unreadable entries to ensure that operations
can succeed on the object. Since higher layers add bitrot checks this is not a big problem.
Cannot downgrade to v1.1 metadata, but since that isn't released, no need for a major bump.
only in case of S3 gateway we have a case where we
need to allow for SSE-S3 headers as passthrough,
If SSE-C headers are passed then they are rejected
if KMS is not configured.
This code is necessary for `mc admin update` command
to work with fips compiled binaries, with fips tags
the releaseInfo will automatically point to fips
specific binaries.
This commit fixes a bug in the put-part
implementation. The SSE headers should be
set as specified by AWS - See:
https://docs.aws.amazon.com/AmazonS3/latest/API/API_UploadPart.html
Now, the MinIO server should set SSE-C headers,
like `x-amz-server-side-encryption-customer-algorithm`.
Fixes#11991
locks can get relinquished when Read() sees io.EOF
leading to prematurely closing of the readers
concurrent writes on the same object can have
undesired consequences here when these locks
are relinquished.
EOF may be sent along with data so queue it up and
return it when the buffer is empty.
Also, when reading data without direct io don't add a buffer
that only results in extra memcopy.
Multiple disks from the same set would be writing concurrently.

This commit adds a self-test for all bitrot algorithms:
- SHA-256
- BLAKE2b
- HighwayHash
The self-test computes an incremental checksum of pseudo-random
messages. If a bitrot algorithm implementation stops working on
some CPU architecture or with a certain Go version this self-test
will prevent the server from starting and silently corrupting data.
For additional context see: minio/highwayhash#19
Metrics calculation was accumulating inital usage across all nodes
rather than using initial usage only once.
Also fixing:
- bug where all peer traffic was going to the same node.
- reset counters when replication status changes from
PENDING -> FAILED
