SMB3 uses a much faster method of signing (which is also better in other ways), AES-CMAC. With the kernel now supporting AES-CMAC since last release, we are overdue to allow SMB3 signing (today only CIFS and SMB2 and SMB2.1, but not SMB3 and SMB3.1 can sign) - and we need this also for checking secure negotation and also per-share encryption (two other new SMB3 features which we need to implement). This patch needs some work in a few areas - for example we need to move signing for SMB2/SMB3 from per-socket to per-user (we may be able to use the "nosharesock" mount option in the interim for the multiuser case), and Shirish found a bug in the earlier authentication overhaul (setting signing flags properly) - but those can be done in followon patches.
