Steve French 50c2f75388 [CIFS] whitespace/formatting fixes
This should be the last big batch of whitespace/formatting fixes.
checkpatch warnings for the cifs directory are down about 90% and
many of the remaining ones are harder to remove or make the code
harder to read.

Steve French 8e6f195af0 [CIFS] Fix oops when Windows server sent bad domain name null terminator
Fixes RedHat bug 211672

Windows sends one byte (instead of two) of null to terminate final Unicode
string (domain name) in session setup response in some cases - this caused
cifs to misalign some informational strings (making it hard to convert
from UCS16 to UTF8).

Thanks to Shaggy for his help and Akemi Yagi for debugging/testing

Steve French 6e659c6399 [CIFS] Fix mount failure when domain not specified
Fixes Samba bugzilla #4176

    When users do not specify their domain on mount, 2.6.18 started sending
    default domain instead of a null domain (which was the only way on some
    servers to use a default domain).  Users of 2.6.18 who did not specify
    their domain name on mounts to certain common Windows servers that were
    members of a domain, but not the domain controller, would get mount
    failures which they did not get in 2.6.18

    This fixes that issue and should remove complaints about mount
    behavior changing.

Serge E. Hallyn 96b644bdec [PATCH] namespaces: utsname: use init_utsname when appropriate
In some places, particularly drivers and __init code, the init utsns is the
appropriate one to use.  This patch replaces those with a the init_utsname
helper.

Changes: Removed several uses of init_utsname().  Hope I picked all the
	right ones in net/ipv4/ipconfig.c.  These are now changed to
	utsname() (the per-process namespace utsname) in the previous
	patch (2/7)

Steve French 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).

Steve French 1717ffc588 [CIFS] NTLMv2 support part 5
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.
