  ksmbd: add buffer validation in session setup (2021-10-20 00:07:10 -0500)

----------------------------------------------------------------
Ten fixes for the ksmbd kernel server:
- 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

Regression test results for current linux-next:
