* [CIFS] Fix SMB2 negotiation support to select only one dialect (based on vers=)Steve French2012-10-011-28/+12
| | | | | | | | | | | | | | | Based on whether the user (on mount command) chooses: vers=3.0 (for smb3.0 support) vers=2.1 (for smb2.1 support) or (with subsequent patch, which will allow SMB2 support) vers=2.0 (for original smb2.02 dialect support) send only one dialect at a time during negotiate (we had been sending a list).

* cifs: replace kvec array in readdata with a single kvecJeff Layton2012-09-251-6/+6

* cifs: convert async read code to use pages array without kmappingJeff Layton2012-09-251-1/+5
| | | | | | | | Replace the "marshal_iov" function with a "read_into_pages" function. That function will copy the read data off the socket and into the pages array, kmapping and reading pages one at a time. Signed-off-by: Jeff Layton <jlayton@redhat.com>

* cifs: change cifs_call_async to use smb_rqst structsJeff Layton2012-09-251-4/+11
| | | | | | | | | | | For now, none of the callers populate rq_pages. That will be done for writes in a later patch. While we're at it, change the prototype of setup_async_request not to need a return pointer argument. Just return the pointer to the mid_q_entry or an ERR_PTR.

* CIFS: Enable signing in SMB2Pavel Shilovsky2012-09-251-6/+46
| | | | | | | | | | | | | | Use hmac-sha256 and rather than hmac-md5 that is used for CIFS/SMB. Signature field in SMB2 header is 16 bytes instead of 8 bytes. Automatically enable signing by client when requested by the server when signing ability is available to the client.
