Pull ksmbd fixes from Steve French:
 "Ten fixes for the ksmbd kernel server, for improved security and
  additional buffer overflow checks:

   - a security improvement to session establishment to reduce the
     possibility of dictionary attacks

   - fix to ensure that maximum i/o size negotiated in the protocol is
     not less than 64K and not more than 8MB to better match expected
     behavior

   - fix for crediting (flow control) important to properly verify that
     sufficient credits are available for the requested operation

   - seven additional buffer overflow, buffer validation checks"
