This commit enhances the docs about IAM encryption.
It adds a quick-start section that explains how to
get started quickly with `MINIO_KMS_SECRET_KEY`
instead of setting up KES.
It also removes the startup message that gets printed
when the server migrates IAM data to plaintext.
We will point this out in the release notes.

With this change, MinIO's ILM supports transitioning objects to a remote tier.
This change includes support for Azure Blob Storage, AWS S3 compatible object
storage incl. MinIO and Google Cloud Storage as remote tier storage backends.
Some new additions include:
- Admin APIs remote tier configuration management
- Simple journal to track remote objects to be 'collected'
This is used by object API handlers which 'mutate' object versions by
overwriting/replacing content (Put/CopyObject) or removing the version
itself (e.g DeleteObjectVersion).
- Rework of previous ILM transition to fit the new model
In the new model, a storage class (a.k.a remote tier) is defined by the
'remote' object storage type (one of s3, azure, GCS), bucket name and a
prefix.
* Fixed bugs, review comments, and more unit-tests
- Leverage inline small object feature
- Migrate legacy objects to the latest object format before transitioning
- Fix restore to particular version if specified
- Extend SharedDataDirCount to handle transitioned and restored objects
- Restore-object should accept version-id for version-suspended bucket (#12091)
- Check if remote tier creds have sufficient permissions
- Bonus minor fixes to existing error messages

This is a minor change to call out the new documentation and warn
users to change their bookmarks. Once we are ready to set up
some redirects, we can remove this page from Gluegun TOC.
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.
- collect real time replication metrics for prometheus.
- add pending_count, failed_count metric for total pending/failed replication operations.
- add API to get replication metrics
- add MRF worker to handle spill-over replication operations
- multiple issues found with replication
- fixes an issue when client sends a bucket
name with `/` at the end from SetRemoteTarget
API call make sure to trim the bucket name to
avoid any extra `/`.
- hold write locks in GetObjectNInfo during replication
to ensure that object version stack is not overwritten
while reading the content.
- add additional protection during WriteMetadata() to
ensure that we always write a valid FileInfo{} and avoid
ever writing empty FileInfo{} to the lowest layers.

prometheus metrics was using total disks instead
of online disk count, when disks were down, this
PR fixes this and also adds a new metric for
total_disk_count
- In username search filter and username format variables we support %s for
replacing with the username.
- In group search filter we support %s for username and %d for the full DN of
the username.
in the case of active-active replication.
This PR also has the following changes:
- add docs on replication design
- fix corner case of completing versioned delete on a delete marker
when the target is down and `mc rm --vid` is performed repeatedly. Instead
the version should still be retained in the `PENDING|FAILED` state until
replication sync completes.
- remove `s3:Replication:OperationCompletedReplication` and
`s3:Replication:OperationFailedReplication` from ObjectCreated
events type
This commit deprecates the native Hashicorp Vault
support and removes the legacy Vault documentation.
The native Hashicorp Vault documentation is marked as
outdated and deprecated for over a year now. We give
another 6 months before we start removing Hashicorp Vault
support and show a deprecation warning when a MinIO server
starts with a native Vault configuration.
This change allows the MinIO server to be configured with a special (read-only)
LDAP account to perform user DN lookups.
The following configuration parameters are added (along with corresponding
environment variables) to LDAP identity configuration (under `identity_ldap`):
- lookup_bind_dn / MINIO_IDENTITY_LDAP_LOOKUP_BIND_DN
- lookup_bind_password / MINIO_IDENTITY_LDAP_LOOKUP_BIND_PASSWORD
- user_dn_search_base_dn / MINIO_IDENTITY_LDAP_USER_DN_SEARCH_BASE_DN
- user_dn_search_filter / MINIO_IDENTITY_LDAP_USER_DN_SEARCH_FILTER
This lookup-bind account is a service account that is used to lookup the user's
DN from their username provided in the STS API. When configured, searching for
the user DN is enabled and configuration of the base DN and filter for search is
required. In this "lookup-bind" mode, the username format is not checked and must
not be specified. This feature is to support Active Directory setups where the
DN cannot be simply derived from the username.
When the lookup-bind is not configured, the old behavior is enabled: the minio
server performs LDAP lookups as the LDAP user making the STS API request and the
username format is checked and configuring it is required.
Fixes support for using multiple base DNs for user search in the LDAP directory
allowing users from different subtrees in the LDAP hierarchy to request
credentials.
- The username in the produced credentials is now the full DN of the LDAP user
to disambiguate users in different base DNs.
Current implementation requires server pools to have
same erasure stripe sizes, to facilitate same SLA
and expectations.
This PR allows server pools to be variadic, i.e they
do not have to be same erasure stripe sizes - instead
they should have SLA for parity ratio.
If the parity ratio cannot be guaranteed by the new
server pool, the deployment is rejected i.e server
pool expansion is not allowed.
Synchronous replication can be enabled by setting the --sync
flag while adding a remote replication target.
This PR also adds proxying on GET/HEAD to another node in a
active-active replication setup in the event of a 404 on the current node.
Use separate sync.Pool for writes/reads
Avoid passing buffers for io.CopyBuffer()
if the writer or reader implement io.WriteTo or io.ReadFrom
respectively then its useless for sync.Pool to allocate
buffers on its own since that will be completely ignored
by the io.CopyBuffer Go implementation.
Improve this wherever we see this to be optimal.
This allows us to be more efficient on memory usage.
```
385 // copyBuffer is the actual implementation of Copy and CopyBuffer.
386 // if buf is nil, one is allocated.
387 func copyBuffer(dst Writer, src Reader, buf []byte) (written int64, err error) {
388 // If the reader has a WriteTo method, use it to do the copy.
389 // Avoids an allocation and a copy.
390 if wt, ok := src.(WriterTo); ok {
391 return wt.WriteTo(dst)
392 }
393 // Similarly, if the writer has a ReadFrom method, use it to do the copy.
394 if rt, ok := dst.(ReaderFrom); ok {
395 return rt.ReadFrom(src)
396 }
```
From readahead package
```
// WriteTo writes data to w until there's no more data to write or when an error occurs.
// The return value n is the number of bytes written.
// Any error encountered during the write is also returned.
func (a *reader) WriteTo(w io.Writer) (n int64, err error) {
if a.err != nil {
return 0, a.err
}
n = 0
for {
err = a.fill()
if err != nil {
return n, err
}
n2, err := w.Write(a.cur.buffer())
a.cur.inc(n2)
n += int64(n2)
if err != nil {
return n, err
}
