This is the first chunk of SMB2 patches. It allows:
1) mount a network share,
2) stat inode information,
3) send echo message,
4) display statistics.
The patchset implements the approach of having ops structure of
protocol-specific callbacks that is used by the generic code.
Changes since version #1:
- add patch that fixes Get/FreeXid
- add patch that prefixes existing CIFS STATUS_ codes with NT_
Pavel Shilovsky (23):
CIFS: Rename Get/FreeXid and make them work with unsigned int
CIFS: Rename 7 error codes to NT_ style
CIFS: Add SMB2 status codes
CIFS: Make transport routines work with SMB2
CIFS: Add SMB2 credits support
CIFS: Make demultiplex_thread work with SMB2 code
CIFS: Respect SMB2 header/max header size
CIFS: Add capability to send SMB2 negotiate message
CIFS: Add session setup/logoff capability for SMB2
CIFS: Add tree connect/disconnect capability for SMB2
CIFS: Process reconnects for SMB2 shares
CIFS: Move getting dfs referalls to ops struct
CIFS: Move informational tcon calls to ops struct
CIFS: Move is_path_accessible to ops struct
CIFS: Add SMB2 support for is_path_accessible
CIFS: Move query inode info code to ops struct
CIFS: Query SMB2 inode info
CIFS: Move building path to root to ops struct
CIFS: Add SMB2 support for build_path_to_root
CIFS: Move echo code to osp struct
CIFS: Add echo request support for SMB2
CIFS: Move clear/print_stats code to ops struct
CIFS: Allow SMB2 statistics to be tracked
Steve French (1):
CIFS: Map SMB2 status codes to POSIX errors

For SMB2 protocol we can add more than one credit for one received
request: it depends on CreditRequest field in SMB2 response header.
Also we divide all requests by type: echos, oplocks and others. Each
type uses its own slot pull.

From: Pavel Shilovsky <piastry-7qunaywFIewox3rIn2DAYQ@public.gmane.org>
and add negotiate request type to let set_credits know that
we are only on negotiate stage and no need to make a decision
about disabling echos and oplocks.

Yes, it makes sense. I've fixed it in smb2-mount branch and will
respost when we finish with other patches from the series.

Looks fine, but I wonder whether we'd be better off just getting rid of
the above warning and the lock_cmd field. The lock_cmd is only used
there, and that firing off warnings just because the call took more
than 1s seems goofy to me. We know that writes long past the EOF can
take a very long time with MS servers. Is the above warning really of
value?
That's a minor nit though and something we can remove later if we
decide to.

It would also be good to turn that into a #define'ed constant and use it in the check below.

It might save a few cycles (and memory) to make the above an array of
__le16's and go ahead and __constant_cpu_to_le16 the values. Then you
wouldn't need to convert the values in the headers below.

The 9 here should probably be a preprocessor constant:
#define SMB2_ERROR_STRUCTURE_SIZE2 __constant_le16_to_cpu(9)
Then you could just compare that to a bare pdu->StructureSize2

Does RFC1001 apply here? The error message above could be clearer.

I wonder...should we also convert the STATUS_* constants to LE values?

Is a stack trace likely to be helpful here? I wouldn't think so...

Printing the actual value might be helpful.

Ditto...

Again, some info that would help us to debug this situation might be

It is probably fine if it makes the cifs code a little cleaner, but I
am more concerned about optimizing the smb2.1/smb3 code than
optimizing the cifs code at this point. I don't

Yeah, agreed. I wouldn't mess with smb1 at this point for this, let's
focus on fixing up the smb2 code. If we need to make changes to the
smb1 code in order to facilitate the smb2 changes then that's fine, but
I'd refrain from doing anything unnecessary to the smb1 code at this
point.
