2013-03-06CIFS: Fix missing of oplock_read value in smb30_values structurePavel Shilovsky1-0/+1
Cc: stable@vger.kernel.org Signed-off-by: Pavel Shilovsky <piastry@etersoft.ru> Signed-off-by: Steve French <sfrench@us.ibm.com>
2013-01-01CIFS: Don't let read only caching for mandatory byte-range locked filesPavel Shilovsky1-0/+2
If we have mandatory byte-range locks on a file we can't cache reads because pagereading may have conflicts with these locks on the server. That's why we should allow level2 oplocks for files without mandatory locks only.

2012-12-09Do not send SMB2 signatures for SMB3 framesSteve French1-0/+68
Restructure code to make SMB2 vs. SMB3 signing a protocol specific op. SMB3 signing (AES_CMAC) is not enabled yet, but this restructuring at least makes sure we don't send an smb2 signature on an smb3 signed connection. A followon patch will add AES_CMAC and enable smb3 signing. Signed-off-by: Steve French <smfrench@gmail.com> Acked-by: Jeff Layton <jlayton@samba.org>
2012-12-05Add SMB2.02 dialect supportSteve French1-0/+17

2012-12-05CIFS: Make use of common cifs_build_path_to_root for CIFS and SMB2Steve French1-18/+0

2012-10-01[CIFS] Fix SMB2 negotiation support to select only one dialect (based on vers=)Steve French1-0/+19
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).

2012-05-23CIFS: Introduce SMB2 mounts as vers=2.1Steve French1-0/+27
As with Linux nfs client, which uses "nfsvers=" or "vers=" to indicate which protocol to use for mount, specifying "vers=2.1" will force an SMB2 mount. When vers is not specified CIFS is used "vers=1" We can eventually autonegotiate down from SMB2 to CIFS when SMB2 is stable enough to make it the default, but this is for the future. At that time we could also implement a "maxprotocol" mount option as smbclient and Samba have today, but that would be premature until SMB2 is stable. Intially the SMB2 Kconfig option will depend on "BROKEN" until the merge is complete, and then be "EXPERIMENTAL" When it is no longer experimental we can consider changing the default protocol to attempt first.
