Cancel old logger/audit targets outside lock (#14927)
When configuring a new target, such as an audit target, the server waits
until all audit events are sent to the audit target before doing the
swap from the old to the new audit target. Therefore current S3 operations
can suffer from this since the audit swap lock will be held.

This behavior is unnecessary as the new audit target can enter in a
functional mode immediately and the old audit will just cancel itself
at its own pace.

lifecycle: Support tags with special characters (#14906)
Object tags can have special characters such as whitespace. However
the current code doesn't properly consider those characters while
evaluating the lifecycle document.

ObjectInfo.UserTags contains an url encoded form of object tags
(e.g. key+1=val)

This commit fixes the issue by using the tags package to parse object tags.

logger lock should be more granular (#14901)
This PR simplifies few things by splitting
the locks between audit, logger targets to
avoid potential contention between them.

any failures inside audit/logger HTTP
targets must only log to console instead
of other targets to avoid cyclical dependency.

avoids unneeded atomic variables instead
uses RWLock to differentiate a more common
read phase v/s lock phase.

fix: multiple fixes in prefix exclude implementation (#14877)
- do not need to restrict prefix exclusions that do not
  have `/` as suffix, relax this requirement as spark may
  have staging folders with other autogenerated characters
  , so we are better off doing full prefix March and skip. 

- multiple delete objects was incorrectly creating a
  null delete marker on a versioned bucket instead of
  creating a proper versioned delete marker.

- do not suspend paths on the excluded prefixes during
  delete operations to avoid creating `null` delete markers,
  honor suspension of versioning only at bucket level for
  delete markers.

feat: implement prefix-level versioning exclusion (#14828)
Spark/Hadoop workloads which use Hadoop MR 
Committer v1/v2 algorithm upload objects to a 
temporary prefix in a bucket. These objects are 
'renamed' to a different prefix on Job commit. 
Object storage admins are forced to configure 
separate ILM policies to expire these objects 
and their versions to reclaim space.

Our solution:

This can be avoided by simply marking objects 
under these prefixes to be excluded from versioning, 
as shown below. Consequently, these objects are 
excluded from replication, and don't require ILM 
policies to prune unnecessary versions.

-  MinIO Extension to Bucket Version Configuration
```xml
<VersioningConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/"> 
        <Status>Enabled</Status>
        <ExcludeFolders>true</ExcludeFolders>
        <ExcludedPrefixes>
          <Prefix>app1-jobs/*/_temporary/</Prefix>
        </ExcludedPrefixes>
        <ExcludedPrefixes>
          <Prefix>app2-jobs/*/__magic/</Prefix>
        </ExcludedPrefixes>

        <!-- .. up to 10 prefixes in all -->     
</VersioningConfiguration>
```
Note: `ExcludeFolders` excludes all folders in a bucket 
from versioning. This is required to prevent the parent 
folders from accumulating delete markers, especially
those which are shared across spark workloads 
spanning projects/teams.

- To enable version exclusion on a list of prefixes

```
mc version enable --excluded-prefixes "app1-jobs/*/_temporary/,app2-jobs/*/_magic," --exclude-prefix-marker myminio/test

etag: add Format and Decrypt functions (#14659)
This commit adds two new functions to the
internal `etag` package:
 - `ETag.Format`
 - `Decrypt`

The `Decrypt` function decrypts an encrypted
ETag using a decryption key. It returns not
encrypted / multipart ETags unmodified.

The `Decrypt` function is mainly used when
handling SSE-S3 encrypted single-part objects.
In particular, the ETag of an SSE-S3 encrypted
single-part object needs to be decrypted since
S3 clients expect that this ETag is equal to the
content MD5.

The `ETag.Format` method also covers SSE ETag handling.
MinIO encrypts all ETags of SSE single part objects.
However, only the ETag of SSE-S3 encrypted single part
objects needs to be decrypted.
The ETag of an SSE-C or SSE-KMS single part object
does not correspond to its content MD5 and can be
a random value.
The `ETag.Format` function formats an ETag such that
it is an AWS S3 compliant ETag. In particular, it
returns non-encrypted ETags (single / multipart)
unmodified. However, for encrypted ETags it returns
the trailing 16 bytes as ETag. For encrypted ETags
the last 16 bytes will be a random value.

The main purpose of `Format` is to format ETags
such that clients accept them as well-formed AWS S3
ETags.
It differs from the `String` method since `String`
will return string representations for encrypted
ETags that are not AWS S3 compliant.

kes: add support for encrypted private keys (#14650)
This commit adds support for encrypted KES
client private keys.

Now, it is possible to encrypt the KES client
private key (`MINIO_KMS_KES_KEY_FILE`) with
a password.

For example, KES CLI already supports the
creation of encrypted private keys:
```
kes identity new --encrypt --key client.key --cert client.crt MinIO
```

To decrypt an encrypted private key, the password
needs to be provided:
```
MINIO_KMS_KES_KEY_PASSWORD=<password>
```

etag: fix incorrect multipart detection (#14631)
This commit fixes a subtle bug in the ETag
`IsEncrypted` implementation.

An encrypted ETag may contain random bytes,
i.e. some randomness used for encryption.
This random value can contain a '-' byte
simple due to being randomly generated.

Before, the `IsEncrypted` implementation
incorrectly assumed that an encrypted ETag
cannot contain a '-' since it would be a
multipart ETag. Multipart ETags have a
16 byte value followed by a '-' and the part number.
For example:
```
059ba80b807c3c776fb3bcf3f33e11ae-2
```

However, the following encrypted ETag
```
20000f00db2d90a7b40782d4cff2b41a7799fc1e7ead25972db65150118dfbe2ba76a3c002da28f85c840cd2001a28a9
```
also contains a '-' byte but is not a multipart ETag.

This commit fixes the `IsEncrypted` implementation
simply by checking whether the ETag is at least 32
bytes long. A valid multipart ETag is never 32 bytes
long since a part number must be <= 10000.

However, an encrypted ETag must be at least 32 bytes
long. It contains the encrypted ETag bytes (16 bytes)
and the authentication tag added by the AEAD cipher (again
16 bytes).

add support for SSE-S3 bulk ETag decryption (#14627)
This commit adds support for bulk ETag
decryption for SSE-S3 encrypted objects.

If KES supports a bulk decryption API, then
MinIO will check whether its policy grants
access to this API. If so, MinIO will use
a bulk API call instead of sending encrypted
ETags serially to KES.

Note that MinIO will not use the KES bulk API
if its client certificate is an admin identity.

MinIO will process object listings in batches.
A batch has a configurable size that can be set
via `MINIO_KMS_KES_BULK_API_BATCH_SIZE=N`.
It defaults to `500`.

This env. variable is experimental and may be
renamed / removed in the future.

Fix waitgroup add after wait on config reload (#14584)
Fix `panic: "POST /minio/peer/v21/signalservice?signal=2": sync: WaitGroup is reused before previous Wait has returned`

Log entries already on the channel would cause `logEntry` to increment the

Instead of tracking every single message, just check the send goroutine. Faster

Add local disk health checks (#14447)
The main goal of this PR is to solve the situation where disks stop 
responding to operations. This generally causes an FD build-up and 
eventually will crash the server.

This adds detection of hung disks, where calls on disk get stuck.

We add functionality to `xlStorageDiskIDCheck` where it keeps 
track of the number of concurrent requests on a given disk.

A total number of 100 operations are allowed. If this limit is reached 
we will block (but not reject) new requests, but we will monitor the 
state of the disk.

If no requests have been completed or updated within a 15-second 
window, we mark the disk as offline. Requests that are blocked will be 
unblocked and return an error as "faulty disk".

New requests will be rejected until the disk is marked OK again.

Once a disk has been marked faulty, a check will run every 5 seconds that 
will attempt to write and read back a file. As long as this fails the disk will 
remain faulty.

To prevent lots of long-running requests to mark the disk faulty we 
implement a callback feature that allows updating the status as parts 
of these operations are running.

We add a reader and writer wrapper that will update the status of each 
successful read/write operation. This should allow fine enough granularity 
that a slow, but still operational disk will not reach 15 seconds where 
50 operations have not progressed.

Note that errors themselves are not enough to mark a disk faulty. 
A nil (or io.EOF) error will mark a disk as "good".

* Make concurrent disk setting configurable via `_MINIO_DISK_MAX_CONCURRENT`.

* de-couple IsOnline() from disk health tracker

The purpose of IsOnline() is to ensure that we
reconnect the drive only when the "drive" was

- disconnected from network we need to validate
  if the drive is "correct" and is the same drive
  which belongs to this server.

- drive was replaced we have to format it - we
  support hot swapping of the drives.

IsOnline() is not meant for taking the drive offline
when it is hung, it is not useful we can let the
drive be online instead "return" errors for relevant
calls.

* return errFaultyDisk for DiskInfo() call

Co-authored-by: Harshavardhana <harsha@minio.io>

Possible future Improvements:

* Unify the REST server and local xlStorageDiskIDCheck. This would also improve stats significantly.
* Allow reads/writes to be aborted by the context.
* Add usage stats, concurrent count, blocked operations, etc.

speed up startup sequence for all operations (#14148)
This speed-up is intended for faster startup times
for almost all MinIO operations. Changes here are

- Drives are not re-read for 'format.json' on a regular
  basis once read during init is remembered and refreshed
  at 5 second intervals.

- Do not do O_DIRECT tests on drives with existing 'format.json'
  only fresh setups need this check.

- Parallelize initializing erasureSets for multiple sets.

- Avoid re-reading format.json when migrating 'format.json'
  from really old V1->V2->V3

- Keep a copy of local drives for any given server in memory
  for a quick lookup.

  NewerNoncurrentVersions are present.
- Allow NewerNoncurrentVersions rules on object-locked buckets

license which is a JWT token, these API keys will 
be simple UUID tokens and don't have any embedded

API key on cluster registration, and then it would 
be saved in this config, to be used for subsequent

fix: multi-pool setup make sure acquire locks properly (#13280)
This was a regression introduced in '14bb969782'
this has the potential to cause corruption when
there are concurrent overwrites attempting to update
the content on the namespace.

This PR adds a situation where PutObject(), CopyObject()
compete properly for the same locks with NewMultipartUpload()
however it ends up turning off competing locks for the actual
object with GetObject() and DeleteObject() - since they do not
compete due to concurrent I/O on a versioned bucket it can lead
to loss of versions.

This PR fixes this bug with multi-pool setup with replication
that causes corruption of inlined data due to lack of competing
locks in a multi-pool setup.

Instead CompleteMultipartUpload holds the necessary
locks when finishing the transaction, knowing the exact
location of an object to schedule the multipart upload
doesn't need to compete in this manner, a pool id location
for existing object.

But this of course requires application to make sure to add

sts: add support for certificate-based authentication (#12748)
This commit adds a new STS API for X.509 certificate
authentication.

A client can make an HTTP POST request over a TLS connection
and MinIO will verify the provided client certificate, map it to an 
S3 policy and return temp. S3 credentials to the client.

So, this STS API allows clients to authenticate with X.509
certificates over TLS and obtain temp. S3 credentials.

For more details and examples refer to the docs/sts/tls.md

[LDAP] Support syncing user-group memberships with LDAP service (#12785)
When configured in Lookup Bind mode, the server now periodically queries the
LDAP IDP service to find changes to a user's group memberships, and saves this
info to update the access policies for all temporary and service account
credentials belonging to LDAP users.

use expected MinIO URLs for console (#12770)
when TLS is configured using IPs directly
might interfere and not work properly when
the server is configured with TLS certs but
the certs only have domain certs.

Also additionally allow users to specify
a public accessible URL for console to talk
to MinIO i.e `MINIO_SERVER_URL` this would
allow them to use an external ingress domain
to talk to MinIO. This internally fixes few
problems such as presigned URL generation on
the console UI etc.

This needs to be done additionally for any
MinIO deployments that might have a much more
stricter requirement when running in standalone
mode such as FS or standalone erasure code.

Anonymize hosts in subnet health report (#12627)
Ensure that hostnames / ip addresses are not printed in the subnet
health report. Anonymize them by replacing them with `servern` where `n`
represents the position of the server in the pool.

This is done by building a `host anonymizer` map that maps every
possible value containing the host e.g. host, host:port,
http://host:port, etc to the corresponding anonymized name and using
this map to replace the values at the time of health report generation.

A different logic is used to anonymize host names in the `procinfo`
data, as the host names are part of an ellipses pattern in the process
start command. Here we just replace the prefix/suffix of the ellipses
pattern with their hashes.

61175ef091 Migrate to govendor to avoid limitations of godep
- over the course of a project history every maintainer needs to update
  its dependency packages, the problem essentially with godep is manipulating
  GOPATH - this manipulation leads to static objects created at different locations
  which end up conflicting with the overall functionality of golang.

  This also leads to broken builds. There is no easier way out of this other than
  asking developers to do 'godep restore' all the time. Which perhaps as a practice
  doesn't sound like a clean solution. On the other hand 'godep restore' has its own
  set of problems.

- govendor is a right tool but a stop gap tool until we wait for golangs official
  1.5 version which fixes this vendoring issue once and for all.

- govendor provides consistency in terms of how import paths should be handled unlike
  manipulation GOPATH.

  This has advantages
    - no more compiled objects being referenced in GOPATH and build time GOPATH
      manging which leads to conflicts.
    - proper import paths referencing the exact package a project is dependent on.

 govendor is simple and provides the minimal necessary tooling to achieve this.

 For now this is the right solution.
