19004113f3 vfs_gpfs: Do not map DELETE sharemode access to WRITE
A SMB client can deny the WRITE sharemode, but still grant the DELETE
sharemode. Mapping the requested DELETE access to WRITE access breaks
this case. Fix this by removing the incorrect mapping from DELETE access
to WRITE access.

62d73f5b93 vfs_gpfs: handle EACCES when fetching DOS attributes from xattr
When trying to fetch the DOS attributes via gpfswrap_get_winattrs_path()
if the filesystem doesn't grant READ_ATTR to the file the function fails
with EACCESS.

But according to MS-FSA 2.1.5.1.2.1 "Algorithm to Check Access to an
Existing File" FILE_LIST_DIRECTORY on a directory implies
FILE_READ_ATTRIBUTES for directory entries.

So if the user can open the parent directory for reading this implies
FILE_LIST_DIRECTORY and we can safely call gpfswrap_get_winattrs_path()
with DAC_OVERRIDE_CAPABILITY.

2e8cdda787 vfs_gpfs: remove updating btime from stat VFS calls
This is now handled by the vfs_gpfs_(f)get_dos_attributes. Getting rid
of this in the stat VFS functions is a huge performance saver. perf
report found that in a kernel copy workload smbd was spending
considerable CPU time in vfs_gpfs_(f|l)stat -> gpfs_get_winattrs.

Most of the time the VFS stat caller is not interested in the btime. The
SMB frontend processing around btime is designed to fetch btime together
with DOS attributes via dos_mode() in all places that need these
attributes. That's the way it is implemented in the default VFS module
and that's what vfs_gpfs now does as well for performance reasons.

This makes vfs_gpfs_fstat a null op and I'm therefor removing it.

adf4cea1db vfs_gpfs: update btime in vfs_gpfs_(f)get_dos_attributes
This paves the way for removing btime updates from the stat VFS
functions.

This way we behave like the default VFS module where DOS attributes and
btime are fetched from the same backing store and the frontend is
designed around using dos_mode() -> SMB_VFS_GET_ATTRIBUTES to update
both attributes as necessary in the SMB processing.

6f3b421c4a s3/vfs: merge offline functionality into DOS attributes handling
The offline VFS functions predate the SMB_VFS_{GET|SET}_DOS_ATTRIBUTES()
functions, now that we have these, we can use them for the offline
attribute as well.

The primary reason for this is: performance. Merging both functions has
the benefit that in VFS modules that use same backing store bits for
both offline attribute and DOS attributes (like gpfs), we avoid calling
the backing store twice in dos_mode() and file_set_dosmode().

This commit modifies all existing users of the offline attribute to
adapt to the change, the next commit will then remove the obsolete
offline functions.
