2013-07-10CIFS: Reconnect durable handles for SMB2Pavel Shilovsky1-1/+7
On reconnects, we need to reopen file and then obtain all byte-range locks held by the client. SMB2 protocol provides feature to make this process atomic by reconnecting to the same file handle with all it's byte-range locks. This patch adds this capability for SMB2 shares.

2013-06-26SMB2 FSCTL and IOCTL worker functionSteve French1-0/+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>

2013-06-24Update headers to update various SMB3 ioctl definitionsSteve French1-1/+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>

2012-10-01[CIFS] Fix SMB2 negotiation support to select only one dialect (based on vers=)Steve French1-1/+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).

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.
