a013689ddb [CIFS] Fix cifsd so shuts down when signing fails during mount
Fixes two problems:
1) we dropped down to negotiating lanman if we did not recognize the
mechanism (krb5 e.g.)
2) we did not stop cifsd (thus will fail when doing rmod cifs with
slab free errors) when we fail tcon but have a bad session (which is
the case in which signing is required but we don't allow signing on
the client)

It also turns on extended security flag in the header when passing
"sec=krb5" on mount command (although kerberos support is not done of
course)

to put DCE/RPC over CIFS or run CIFS named

796e5661f6 [CIFS] Change semaphore to mutex for cifs lock_sem
Originally at http://lkml.org/lkml/2006/9/2/86

The recent change to "allow Windows blocking locks to be cancelled via a
CANCEL_LOCK call" introduced a new semaphore in struct cifsFileInfo,
lock_sem.  However, semaphores used as mutexes are deprecated these days,
and there's no reason to add a new one to the kernel.  Therefore, convert
lock_sem to a struct mutex (and also fix one indentation glitch on one of
the lines changed anyway).

9ac00b7d96 [CIFS] Do not send newer QFSInfo to legacy servers which can not support it
Fix dialect negotiation to save off when we have negotiated lanman.
This allows us to avoid sending some somewhat newer requests that the server
can not handle and go directly to the older version (infolevel) of the same
call. Make sure we try to negotiate a level which allows us to get the
server OS (which we check so we can detect Win9x vs. other legacy servers
and eventually work around the Win9x DOS time bug (they reverse date/time
fields).

5815449d1b [CIFS] SessionSetup cleanup part 2
The cifs session setup code has three cases, and a fourth for backlevel
LANMAN2 style session setup needed to be added.  This new session setup
implmentation will eventually replace the other three and should be
easier to read while fixing a few minor problems (not setting
the LARGE READ/WRITEX flags when NTLMSSP was negotiated for example) and
adding support for NTLMv2 (which will be added with the next patch. In the
meantime, this code is marked in an CONFIG_CIFS_EXPERIMENTAL block and will
not be turned on by default until it is tested against more server types.

a10faeb2a3 [CIFS] Support for mounting to older, pre-CIFS servers added. This
allows specifying an RFC1001 target "called" name (netbios name of the
server, which can now be pecified as mount option "servernetbiosname"
but will eventually be passed in automatically on retry of host down
error messages caused when server refuses to handle default server
name and can not handle port 445). This is an important step, but
additional testing and fixup is needed to add remaining function needed
for these.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
