4e1e7fb9e8 bundle up Unix SET_PATH_INFO args into a struct and change name
We'd like to be able to use the unix SET_PATH_INFO_BASIC args to set
file times as well, but that makes the argument list rather long. Bundle
up the args for unix SET_PATH_INFO call into a struct. For now, we don't
actually use the times fields anywhere. That will be done in a follow-on
patch.

67750fb9e0 [CIFS] when not using unix extensions, check for and set ATTR_READONLY on create and mkdir
When creating a directory on a CIFS share without POSIX extensions,
and the given mode has no write bits set, set the ATTR_READONLY bit.

When creating a file, set ATTR_READONLY if the create mode has no write
bits set and we're not using unix extensions.

There are some comments about this being problematic due to the VFS
splitting creates into 2 parts. I'm not sure what that's actually
talking about, but I'm assuming that it has something to do with how
mknod is implemented. In the simple case where we have no unix
extensions and we're just creating a regular file, there's no reason
we can't set ATTR_READONLY.

38e2aff670 [CIFS] Do not negotiate new POSIX_PATH_OPERATIONS_CAP yet
Samba server now expects that clients which send the new
POSIX_PATH_OPERATIONS_CAP send all opens with this new
SMB - and expects that clients that could send the new
posix open/create but don't as indicating that they really
want Windows semantics on that handle (which allows Samba
to support clients which want to support both types of
behaviors on different handles on the same mount)

We will put this capability back in the SetFSInfo
negotiation with servers like Samba when the
new POSIXCreate (create/open/mkdir) code is finished.

c7af1857ef [CIFS] Fix set file size to zero when doing chmod to Samba 3.0.26pre
In fixing a bug Samba 3.0.26pre allowed some clients (including Linux cifs
client) to change file size to zero in SET_FILE_UNIX_BASIC (which Linux cifs
client uses for chmod).

The server has been "fixed" now but that also fixes the client to net send
file size zero on chmod.

Fixes Samba bugzilla bug # 4418.

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).

0753ca7bc2 [CIFS] Change pragma pack(1) to attribute(packed) to allow cifs on arm to access
unaligned structures coming in off the wire

gcc on arm processors generates very odd code with pragma pack specified -
although it does pack the structures in some sense - it does not allow you
to access unaligned elements in nested structures at the right offset as other
architectures do.  Oddly enough though, specifying the structures as packed
the long way - one by one with the packed attribute does work.  Rather than
fighting over whether this is a gcc bug or some obscure side effect
of pragma pack, it is easier to do what most (all but 96 other places in
the kernel) do - and replace pragma pack with dozens of attribute(packed)
structure qualifiers.  Much more verbose ... but at least it works.
