Anis Elleuch b05825ffe8 s3: Fix precondition failed in CopyObjectPart when src is encrypted (#7276)
CopyObject precondition checks into GetObjectReader
in order to perform SSE-C pre-condition checks using the
last 32 bytes of encrypted ETag rather than the decrypted
ETag

This also necessitates moving precondition checks for
gateways to gateway layer rather than object handler check

Harshavardhana 30135eed86 Redo how to handle stale dangling files (#7171)
foo.CORRUPTED should never be created because when
multiple sets are involved we would hash the file
to wrong a location, this PR removes the code.

But allows DeleteBucket() to work properly to delete
dangling buckets/objects. Also adds another option
to Healing where a user needs to specify `--remove`
such that all dangling objects will be deleted with
user confirmation.

poornas 5a80cbec2a Add double encryption at S3 gateway. (#6423)
This PR adds pass-through, single encryption at gateway and double
encryption support (gateway encryption with pass through of SSE
headers to backend).

If KMS is set up (either with Vault as KMS or using
MINIO_SSE_MASTER_KEY),gateway will automatically perform
single encryption. If MINIO_GATEWAY_SSE is set up in addition to
Vault KMS, double encryption is performed.When neither KMS nor
MINIO_GATEWAY_SSE is set, do a pass through to backend.

When double encryption is specified, MINIO_GATEWAY_SSE can be set to
"C" for SSE-C encryption at gateway and backend, "S3" for SSE-S3
encryption at gateway/backend or both to support more than one option.

Fixes #6323, #6696

Harshavardhana 12a6523fb2 Do not delete parts in multipart if 0 bytes (#6855)
This can create inconsistencies i.e Parts might have
lesser number of parts than ChecksumInfos. This will
result in object to be not readable.

This PR also allows for deleting previously created
corrupted objects.

poornas 5f6d717b7a Fix: Preserve MD5Sum for SSE encrypted objects (#6680)
To conform with AWS S3 Spec on ETag for SSE-S3 encrypted objects,
encrypt client sent MD5Sum and store it on backend as ETag.Extend
this behavior to SSE-C encrypted objects.

Harshavardhana 36990aeafd Avoid double bucket validation in DeleteObjectHandler (#6720)
On a heavily loaded server, getBucketInfo() becomes slow,
one can easily observe deleting an object causes many
additional network calls.

This PR is to let the underlying call return the actual
error and write it back to the client.

Anis Elleuch 6590aba6d2 xl: PUT an empty dir on an existing prefix succeed (#6658)
This commit fixes a regression introduced in f187a16962
the regression returned AccessDenied when a client is trying to create an empty
directory on a existing prefix, though it should return 200 OK to be close as
much as possible to S3 specification.

Anis Elleuch 362ebdcbab xl: Add '.CORRUPTED' prefix to corrupted objects (#6592)

Anis Elleuch f187a16962 xl: Require full write quorum in rename() as general rule (#6535)
Simplify the logic of using rename() in xl. Currently, renaming
doesn't require the source object/dir to be existent in at least
read quorum disks, since there is no apparent reason for it
to be as a general rule, this commit will just simplify the
logic to avoid possible inconsistency in the backend in the future.

Anis Elleuch ea9408ccbb worm: when enabled, avoid renaming the existing object in tmp directory (#6560)
In XL PutObject & CompleteMultipartUpload, the existing object is renamed
to the temporary directory before checking if worm is enabled or not.

Most of the times, this doesn't cause an issue unless two uploads to the
same location occurs at the same time. Since there is no locking in object
handlers, both uploads will reach XL layer. The second client acquiring
write lock in put object or complete upload in XL will rename the object
to the temporary directory before doing the check and returning the error (wrong!).

This commit fixes then the behavior: no rename to temporary directory if
worm is enabled.

Anis Elleuch 6d5f2a4391 Better support of empty directories (#5890)
Better support of HEAD and listing of zero sized objects with trailing
slash (a.k.a empty directory). For that, isLeafDir function is added
to indicate if the specified object is an empty directory or not. Each
backend (xl, fs) has the responsibility to store that information.
Currently, in both of XL & FS, an empty directory is represented by
an empty directory in the backend.

isLeafDir() checks if the given path is an empty directory or not,
since dir listing is costly if the latter contains too many objects,
readDirN() is added in this PR to list only N number of entries.
In isLeadDir(), we will only list one entry to check if a directory
is empty or not.
