(cherry picked from 89b57148115479eef074b8d3f86c4c86c96ac969 commit)
NTLMv2 authentication (stronger authentication than default NTLM) which
many servers support now works. There was a problem with the construction
of the security blob in the older code. Currently requires
/proc/fs/cifs/Experimental to be set to 2
and
/proc/fs/cifs/SecurityFlags to be set to 0x4004 (to require using
NTLMv2 instead of default of NTLM)
Next we will check signing to make sure optional NTLMv2 packet signing also
works.

Fixes oops to OS/2 on ls and removes redundant NTCreateX calls to servers
which do not support NT SMBs. Key operations to OS/2 work.

to return . and .. as well as updates to changelog and cifs readme.

- slow down negprot 1ms during mount when RFC1001 over port 139
to give buggy servers time to clear sess_init
- remap some plausible but incorrect SMB return codes to the
right ones in truncate and hardlink paths

Samba (version 3) server support for this is also currently being
done. This client code is in an experimental path (requires enabling
/proc/fs/cifs/Experimental) while it is being tested.

case when Unix Extensions is not enabled and setuids is enabled. This is
necessary to fix the hole in which chown could be allowed for non-root
users in some cases if root mounted, and also to display the mode and uid
properly in some cases.

umount or readdir e.g.) so the client recognizes the new file on

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.
