xl: Implement posix.DeletePrefixes to enhance delete perf (#9100)
Bulk delete API was using cleanupObjectsBulk() which calls posix
listing and delete API to remove objects internal files in the
backend (xl.json and parts) one by one.

Add DeletePrefixes in the storage API to remove the content
of a directory in a single call.

Also use a remove goroutine for each disk to accelerate removal.

Add a generic Walk()'er to list a bucket, optinally prefix (#9026)
This generic Walk() is used by likes of Lifecyle, or
KMS to rotate keys or any other functionality which
relies on this functionality.

allow rolling upgrades, remove same MinIO version requirement (#9033)
Upgrades between releases are failing due to strict
rule to avoid rolling upgrades, it is enough to
bump up APIs between versions to allow for quorum
failure and wait times. Authentication failures are
catastrophic in nature which leads to server not
be able to upgrade properly.

fix: multi-delete API write quorum failures (#8926)
multi-delete API failed with write quorum errors
under following situations

- list of files requested for delete doesn't exist
  anymore can lead to quorum errors and failure
- due to usage of query param for paths, for really
  long paths MinIO server rejects these requests as
  malformed as unexpected.

This was reproduced with warp

jwt: Simplify JWT parsing (#8802)
JWT parsing is simplified by using a custom claim
data structure such as MapClaims{}, also writes
a custom Unmarshaller for faster unmarshalling.

- Avoid as much reflections as possible
- Provide the right types for functions as much
  as possible
- Avoid strings.Join, strings.Split to reduce
  allocations, rely on indexes directly.

Harshavardhana 0879a4f743 rest/storage: Remove racy LastError usage (#8817)
instead perform a liveness check call to
verify if server is online and print relevant
errors.

Also introduce a StorageErr string error type
instead of errors.New() deprecate usage of
VerifyFileError, DeleteFileError for gob,
change in datastructure also requires bump in
storage REST version to v13.

Harshavardhana 4e63e0e372 Return appropriate errors API versions changes across REST APIs (#8480)
This PR adds code to appropriately handle versioning issues
that come up quite constantly across our API changes. Currently
we were also routing our requests wrong which sort of made it
harder to write a consistent error handling code to appropriately
reject or honor requests.

This PR potentially fixes issues

 - old mc is used against new minio release which is incompatible
   returns an appropriate for client action.
 - any older servers talking to each other, report appropriate error
 - incompatible peer servers should report error and reject the calls
   with appropriate error

Harshavardhana ff5bf51952 admin/heal: Fix deep healing to heal objects under more conditions (#8321)
- Heal if the part.1 is truncated from its original size
- Heal if the part.1 fails while being verified in between
- Heal if the part.1 fails while being at a certain offset

Other cleanups include make sure to flush the HTTP responses
properly from storage-rest-server, avoid using 'defer' to
improve call latency. 'defer' incurs latency avoid them
in our hot-paths such as storage-rest handlers.

Fix error handling in DeleteFileBulk storage handler (#8327)
errors.errorString() cannot be marshalled by gob
encoder, so using a slice of []error would fail
to be encoded. This leads to no errors being
generated instead gob.Decoder on the storage-client
would see an io.EOF

To avoid such bugs introduce a typed error for
handling such translations and register this type
for gob encoding support.

posix.VerifyFile() doesn't know how to check if a file

an error so healing empty parts can work properly.

Harshavardhana 16c648b109 Remove "Connection" close instead reduce MaxConns per host (#7654)
This is necessary to avoid connection build up between servers
unexpectedly for example in a situation where 16 servers are
talking to each other and one server now allows a maximum of

15*4096 = 61440 idle connections

Will be kept in pool. Such a large pool is perhaps inefficient for
many reasons and also affects overall system resources.

This PR also reduces idleConnection timeout from 120 secs to 60 secs.

Lock: Use REST API instead of RPC (#7469)
In distributed mode, use REST API to acquire and manage locks instead
of RPC.

RPC has been completely removed from MinIO source.

Since we are moving from RPC to REST, we cannot use rolling upgrades as the
nodes that have not yet been upgraded cannot talk to the ones that have
been upgraded.

We expect all minio processes on all nodes to be stopped and then the
upgrade process to be completed.

Also force http1.1 for inter-node communication

Andreas Auernhammer 9a740736a4 fix privilege escalation against inter-node communication (#7474)
This commit fixes another privilege escalation issue
abusing the inter-node communication of distributed
servers to obtain/modify the server configuration.

The inter-node communication is authenticated using
JWT-Tokens. Further, IAM users accessing the cluster
via the web UI also get a JWT token and the browser
will add this "user" JWT token to each the request.

Now, a user can extract that JWT token an can craft
HTTP POST requests for the inter-node communication
API endpoint. Since the server accepts ANY valid
JWT token it also accepts inter-node commands from
an authenticated user such that the user can execute
arbitrary commands bypassing the IAM policy engine
and impersonate other users, change its own IAM policy
or extract the admin access/secret key.

This is fixed by only accepting "admin" JWT tokens
(tokens containing the admin access key - and therefore
were generated with the admin secret key). Consequently,
only the admin user can execute such inter-node commands.
