Shyam Prasad N ba978e8325 cifs: cifs_ses_mark_for_reconnect should also update reconnect bits
Recent restructuring of cifs_reconnect introduced a helper func
named cifs_ses_mark_for_reconnect, which updates the state of tcp
session for all the channels of a session for reconnect.

However, this does not update the session state and chans_need_reconnect
bitmask. This change fixes that.

Also, cifs_mark_tcp_sess_for_reconnect should mark set the bitmask
for all channels when the whole session is marked for reconnect.
Fixed that here too.

Shyam Prasad N 080dc5e565 cifs: take cifs_tcp_ses_lock for status checks
While checking/updating status for tcp ses, smb ses or tcon,
we take GlobalMid_Lock. This doesn't make any sense.
Replaced it with cifs_tcp_ses_lock.

Ideally, we should take a spin lock per struct.
But since tcp ses, smb ses and tcon objects won't add up to a lot,
I think there should not be too much contention.

Also, in few other places, these are checked without locking.
Added locking for these.

checkpatch complains about source files with filenames (e.g. in
these cases just below the SPDX header in comments at the top of
various files in fs/cifs). It also is helpful to change this now
so will be less confusing when the parent directory is renamed
e.g. from fs/cifs to fs/smb_client (or fs/smbfs)

Roberto Bergantinos Corpas a3713ec3d7 cifs`: handle ERRBaduid for SMB1
If server returns ERRBaduid but does not reset transport connection,
we'll keep sending command with a non-valid UID for the server as long
as transport is healthy, without actually recovering. This have been
observed on the field.

This patch adds ERRBaduid handling so that we set CifsNeedReconnect.

map_and_check_smb_error() can be modified to extend use cases.

Joe Perches a0a3036b81 cifs: Standardize logging output
Use pr_fmt to standardize all logging for fs/cifs.

Some logging output had no CIFS: specific prefix.

Now all output has one of three prefixes:

o CIFS:
o CIFS: VFS:
o Root-CIFS:

Miscellanea:

o Convert printks to pr_<level>
o Neaten macro definitions
o Remove embedded CIFS: prefixes from formats
o Convert "illegal" to "invalid"
o Coalesce formats
o Add missing '\n' format terminations
o Consolidate multiple cifs_dbg continuations into single calls

Jeff Layton cce0244ab0 cifs: change ERRnomem error mapping from ENOMEM to EREMOTEIO
Sometimes, the server will report an error that basically indicates
that it's running out of resources. These include these under SMB1:

NT_STATUS_NO_MEMORY
NT_STATUS_SECTION_TOO_BIG
NT_STATUS_TOO_MANY_PAGING_FILES

...and this one under SMB2:

STATUS_NO_MEMORY

Currently, this gets mapped to ENOMEM by the client, but that's
confusing as an ENOMEM error is typically an indicator that the
client is out of memory.

Change these errors to instead map to EREMOTEIO to indicate that
the problem is actually server-side and not on the client.

Joe Perches f96637be08 [CIFS] cifs: Rename cERROR and cFYI to cifs_dbg
It's not obvious from reading the macro names that these macros
are for debugging.  Convert the names to a single more typical
kernel style cifs_dbg macro.

	cERROR(1, ...)   -> cifs_dbg(VFS, ...)
	cFYI(1, ...)     -> cifs_dbg(FYI, ...)
	cFYI(DBG2, ...)  -> cifs_dbg(NOISY, ...)

Move the terminating format newline from the macro to the call site.

Add CONFIG_CIFS_DEBUG function cifs_vfs_err to emit the
"CIFS VFS: " prefix for VFS messages.

Size is reduced ~ 1% when CONFIG_CIFS_DEBUG is set (default y)

$ size fs/cifs/cifs.ko*
   text    data     bss     dec     hex filename
 265245	   2525	    132	 267902	  4167e	fs/cifs/cifs.ko.new
 268359    2525     132  271016   422a8 fs/cifs/cifs.ko.old

Other miscellaneous changes around these conversions:

o Miscellaneous typo fixes
o Add terminating \n's to almost all formats and remove them
  from the macros to be more kernel style like.  A few formats
  previously had defective \n's
o Remove unnecessary OOM messages as kmalloc() calls dump_stack
o Coalesce formats to make grep easier,
  added missing spaces when coalescing formats
o Use %s, __func__ instead of embedded function name
o Removed unnecessary "cifs: " prefixes
o Convert kzalloc with multiply to kcalloc
o Remove unused cifswarn macro

Jeff Layton 4f2b86aba8 cifs: change DOS/NT/POSIX mapping of ERRnoresource
ERRnoresource is an ERRSRV level (aka server-side) error and means "No
resources currently available for request". Currently that maps to POSIX
-ENOBUFS. No NT errors map to it currently.

NT_STATUS_INSUFFICIENT_RESOURCES and NT_STATUS_INSUFF_SERVER_RESOURCES
are also similar in meaning. Currently the client maps those to
ERRnomem, which maps to -ENOMEM in POSIX.

All of these mappings seem to be quite wrong to me and are confusing for
users. All of the above errors indicate problems on the server, not the
client. Reporting -ENOMEM or -ENOBUFS implies that the client is running
out of resources.

This patch changes those mappings. The NT_* errors are changed to map to
the SRV level ERRnoresource. That error is in turn changed to return
-EREMOTEIO which is the only POSIX error I could find that conveys that
something went wrong on the server. While we're at it, change the SMB2
equivalent error to return the same.

We can also eliminate the check for a receive_len that's too big or too

socket if that occurs, while setting the midStatus to MALFORMED. It'll
never call this code if that's the case.

Finally do a little cleanup. Use "goto out" on errors so that the flow
of code in the normal case is more evident. Also switch the logErr
variable in map_smb_to_linux_error to a bool.

Jeff Layton 820a803ffa cifs: keep BCC in little-endian format
This is the same patch as originally posted, just with some merge
conflicts fixed up...

Currently, the ByteCount is usually converted to host-endian on receive.
This is confusing however, as we need to keep two sets of routines for
accessing it, and keep track of when to use each routine. Munging
received packets like this also limits when the signature can be
calulated.

Simplify the code by keeping the received ByteCount in little-endian
format. This allows us to eliminate a set of routines for accessing it
and we can now drop the *_le suffixes from the accessor functions since
that's now implied.

While we're at it, switch all of the places that read the ByteCount
directly to use the get_bcc inline which should also clean up some
unaligned accesses.

This patch should replace the patch I sent a couple of weeks ago to

Currently we set this in cifs_find_tcp_session, but that's more of a

Have it call cifs_convert_address and then set the port.

This also allows us to skip passing in the port as a separate parm to
cifs_find_tcp_session.

Also, change cifs_convert_address take a struct sockaddr * rather than
void * to make it clearer how this function should be called.

index suitable for stuffing into the sin6_scope_id field.

This should allow people to mount servers on IPv6 link-local addresses.

Jeff Layton c4a2c08db7 cifs: make cnvrtDosUnixTm take a little-endian args and an offset
The callers primarily end up converting the args from le anyway. Also,
most of the callers end up needing to add an offset to the result. The
exception to these rules is cnvrtDosCifsTm, but there are no callers of
that function, so we might as well remove it.

Christoph had noticed too many ifdefs in the CIFS code making it
hard to read.  This patch removes about a quarter of them from
the C files in cifs by improving a few key ifdefs in the .h files.

Steve French 1fb64bfc45 [CIFS] when mount helper missing fix slash wrong direction in share
Kernel bugzilla bug #9228

If mount helper (mount.cifs) missing, mounts with form like
//10.11.12.13/c$ would not work (only mounts with slash e.g.
//10.11.12.13\\c$ would work) due to problem with slash supposed
to be converted to backslash by the mount helper (which is not
there).

If we fail on converting an IPv4 address in in4_pton then
try to canonicalize the first slash (ie between sharename
and host ip address) if necessary.  If we have to retry
to check for IPv6 address the slash is already converted
if necessary.
