2012-10-01[CIFS] Fix SMB2 negotiation support to select only one dialect (based on vers=)Steve French1-28/+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).

2012-09-24cifs: replace kvec array in readdata with a single kvecJeff Layton1-6/+6
The array is no longer needed. We just need a single kvec to hold the header for signature checking. Signed-off-by: Jeff Layton <jlayton@redhat.com>
2012-09-24cifs: convert async read code to use pages array without kmappingJeff Layton1-1/+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>

2012-09-24cifs: change cifs_call_async to use smb_rqst structsJeff Layton1-4/+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.

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.
