3d3d01cda8 s3: smbd: Tweak openat_pathref_dirfsp_nosymlink() to NULL out fsp->fsp_name after calling fd_close() on intermediate directories, rather than before.
vfs_virusfilter expects a non-NULL fsp->fsp_name to use for printing debugs
(it always indirects fsp->fsp_name). vfs_fruit also does the same, so would
also crash in fruit_close() with 'debug level = 10' and vfs_default:VFS_OPEN_HOW_RESOLVE_NO_SYMLINKS = no
set (we don't test with that which is why we haven't noticed
this before).

98d84192a0 s3:utils:mdsearch go to cmdline_messaging_context_free
mdsearch utility would exit earlier with failure in several cases like:
a. samba server is not running yet,
[~] # mdsearch -Uuser%password1 ${server} Public '*=="Samba"'
main: Cannot connect to server: NT_STATUS_CONNECTION_REFUSED

b. spotlight backend service is not ready yet,
[~] # mdsearch -Uuser%password1 ${server} Public '*=="Samba"'
Failed to connect mdssvc

c. mdsearch utility paramters is not as expecred,
[~] # mdsearch -Uuser%password1 ${server} share_not_exist '*=="Samba"'
mdscli_search failed

And in the mean while once mdsearch utility exit earlier with failure,
the lock files are left behind in the directory 'msg.sock' and 'msg.lock'.
If a script to run mdsearch utility in a loop,
this might result in used space slowly growing-up on underlying filesystem.

Supposed to add a new label 'fail_free_messaging',
make it go through the cmdline_messaging_context_free() which deletes the
lock files in the directory msg.sock and msg.lock before mdsearch utility
is exiting with failure.

de5d31f452 s3:smbstatus: go to cmdline_messaging_context_free
If the locking.tdb is not found,
(for example, fresh new installed samba server is not running yet)
smbstatus utility would exit earlier,
and lock files are left behind in the directory 'msg.sock' and 'msg.lock'.
Consider that a script to run smbstatus utility in a loop,
this might result in used space slowly growing-up on the underlying filesystem.
Since the samba server is not running yet,
there is no cleanupd daemon could delete these files to reclaim space.

Supposed to use 'ret = 0; goto done;' instead of exit(0),
this would go through the cmdline_messaging_context_free() which deletes
the lock files in the directory msg.sock and msg.lock before smbstatus
utility is exiting.

2fe95f6a30 s3: smbd: Ensure check_fsp_ntquota_handle() doesn't send SMB1 error packets.
check_fsp_ntquota_handle() is called from SMB2 codepaths as
well as from SMB1. Even in the SMB1 cases the callers of
check_fsp_ntquota_handle() handle sendng the error packet when
check_fsp_ntquota_handle returns false so on a 'return false'
we'd end up sending an error packet twice.

The SMB2 callers of check_fsp_ntquota_handle()
already check that fsp is valid, so there's
no danger of us sending an SMB1 error packet
over the SMB2 stream (so I'm not classing
this as a bug to be back-ported).

Fix check_fsp_ntquota_handle() by inlineing
the check_fsp_open() functionality without
the reply_nterror() calls.

This will allow the next commit to move check_fsp_open()
with the implicit reply_nterror() and also check_fsp()
(which calls check_fsp_open()) into the SMB1 smb1_reply.c
file as SMB1-only code.
