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.
