Merge tag '4.18-rc3-smb3fixes' of git://git.samba.org/sfrench/cifs-2.6

Pull cifs fixes from Steve French:
 "Five smb3/cifs fixes for stable (including for some leaks and memory
  overwrites) and also a few fixes for recent regressions in packet
  signing.

  Additional testing at the recent SMB3 test event, and some good work
  by Paulo and others spotted the issues fixed here. In addition to my
  xfstest runs on these, Aurelien and Stefano did additional test runs
  to verify this set"
