8d22b9edff Revert "smbd: fullpath based on fsp->fsp_name may contain an @GMT token"
This reverts commit e593c38f5a8602be497a29e145ccdd4f9cc595e7.

As stated in the original commit message, "When canonicalize_snapshot_path()
starts actually stripping off @GMT tokens, we can remove this again."

canonicalize_snapshot_path() now strips off @GMT tokens from
any SMB1 names, so this is now not needed anymore.

2992891e27 s3: smbd: Move the initialization of the filename and the call to canonicalize_snapshot_path() *before* zero-length string checks.
canonicalize_snapshot_path() may eat the incoming pathname in total
for SMB1, so we need to check after that call.

Fix the zero-length string check to look at state->smb_fname->base_name
instead of state->orig_path.

55877f958a smbd: remove processing of @GMT tokens from the SMB2 server
Setting this flag was a hokey hack to trigger @GMT token processing in
filename_convert(). Now that all internal processing is based on struct
smb_filename.NTTIME twrp, we can remove this hack.

With this change, paths containing @GMT tokens received over SMB2 are
subsequently processed unchanged, the @GMT token is not stripped and will hit
the filesystem, mostly resulting in NT_STATUS_NOT_FOUND failures which is the
same behaviour as Windows.

6e364c5453 smbd: strip @GMT token in canonicalize_snapshot_path()
smbd and all previous-versions implementing VFS modules have been patched to
work with struct smb_filename.NTTIME twrp, so we can now safely strip @GMT
tokens from paths.

This also means that "@GMT-something/foo" and "foo" will both come out as "foo",
so we have to take care of the stat-cache now and change it to take and use an
additional twrp arg.

At the same time remove @GMT stripping from shadow_copy2. In theory this could
be made a seperate commit, but due to the absolute path and pstripped logic, it
felt too cumbersome to attempt this.

Leaving the exercize of removing the now unneeded stripped logic to a future
patchset.

Use smb_fname->twrp instead if the @GMT token and assert both the twrp value and
the converted @GMT string token have the same value.

With this commit passing CI (which it did), we can somewhat safely assume that
anything that calls into the VFS stack is correctly passing struct
smb_filename.twrp from unix_convert() to the VFS without loosing the twrp value
in one of the myriad places where we copy the original struct smb_filename value
one way or another.

b74653f2cd smbd: add twrp arg to synthetic_smb_fname()
Most places take twrp from a local struct smb_filename variable that the
function is working on. Some don't for various reasons:

o synthetic_smb_fname_split() is only called in very few places where we don't
  expect twrp paths

o implementations of SMB_VFS_GETWD(), SMB_VFS_FS_CAPABILITIES() and
  SMB_VFS_REALPATH() return the systems view of cwd and realpath without twrp info

o VFS modules implementing previous-versions support (vfs_ceph_snapshots,
  vfs_shadow_copy2, vfs_snapper) synthesize raw paths that are passed to VFS NEXT
  functions and therefor do not use twrp

o vfs_fruit: macOS doesn't support VSS

o vfs_recycle: in recycle_create_dir() we need a raw OS path to create a directory

o vfs_virusfilter: a few places where we need raw OS paths

o vfs_xattr_tdb: needs a raw OS path for SMB_VFS_NEXT_STAT()

o printing and rpc server: don't support VSS

o vfs_default_durable_reconnect: no Durable Handles on VSS handles, this might
  be enhances in the future. No idea if Windows supports this.

o get_real_filename_full_scan: hm.... FIXME??

o get_original_lcomp: working on a raw path

o msdfs: doesn't support VSS

o vfs_get_ntquota: synthesizes an smb_filename from ".", so doesn't support VSS
  even though VFS modules implement it

o fd_open: conn_rootdir_fname is a raw path

o msg_file_was_renamed: obvious

o open_np_file: pipes don't support VSS

o Python bindings: get's a raw path from the caller

o set_conn_connectpath: raw path

o set_conn_connectpath: raw path

o torture: gets raw paths from the caller
