  ksmbd: use LOOKUP_BENEATH to prevent the out of share access
(2021-09-24 21:25:23 -0500)

----------------------------------------------------------------
Five fixes for the ksmbd kernel server, including three security fixes:
- removing follow symlinks support
- converting to use LOOKUP_BENEATH to prevent out of share access
- SMB3 compounding security fix
-fix for returning the default streams correctly, fixing a bug when
writing ppt or doc files from some clients
- logging more clearly that ksmbd is experimental (at module load time)

Functional testing passed (e.g.
http://smb3-test-rhel-75.southcentralus.cloudapp.azure.com/#/builders/8/builds/73).
Additional patches are being reviewed, addressing the remaining
potential overflows found in the security reviews.
