* SMB2 FSCTL and IOCTL worker functionSteve French2013-06-271-0/+23
| | | | | | | | | | | | | | | | | | | | | | | This worker function is needed to send SMB2 fsctl (and ioctl) requests including: validating negotiation info (secure negotiate) querying the servers network interfaces copy offload (refcopy) Followon patches for the above three will use this. This patch also does general validation of the response. In the future, as David Disseldorp notes, for the copychunk ioctl case, we will want to enhance the response processing to allow returning the chunk request limits to the caller (even though the server returns an error, in that case we would return data that the caller could use - see 2.2.32.1). See MS-SMB2 Section 2.2.31 for more details on format of fsctl. Acked-by: Pavel Shilovsky <piastry@etersoft.ru> Signed-off-by: Steve French <smfrench@gmail.com>

* Update headers to update various SMB3 ioctl definitionsSteve French2013-06-241-1/+47
| | | | | | | | | | | | MS-SMB2 Section 2.2.31 lists fsctls. Update our list of valid cifs/smb2/smb3 fsctls and some related structs based on more recent version of docs. Additional detail on less common ones can be found in MS-FSCC section 2.3. CopyChunk (server side copy, ie refcopy) will depend on a few of these Signed-off-by: Steve French <smfrench@gmail.com>

* [CIFS] Fix SMB2 negotiation support to select only one dialect (based on vers=)Steve French2012-10-011-1/+11
| | | | | | | | | | | | | | | 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: Map SMB2 status codes to POSIX errorsSteve French2012-07-241-0/+56
Add mapping table for 32 bit SMB2 status codes to linux errors. Note that SMB2 does not use DOS/OS2 errors (ever) so mapping to DOS/OS2 errors as a common network subset (as we do for cifs) doesn't help. And note that the set of status codes is much more complete here.
