[GIT PULL] SELinux patches for v5.18

[Paul Moore]

Linus,

We've got a number of SELinux patches queued up for v5.18, the
highlights are below:

- Fixup the security_fs_context_parse_param() LSM hook so it executes
all of the LSM hook implementations unless a serious error occurs.  We
also correct the SELinux hook implementation so that it returns zero
on success.

- In addition to a few SELinux mount option parsing fixes, we
simplified the parsing by moving it earlier in the process.  The logic
was that it was unlikely an admin/user would use the new mount API and
not have the policy loaded before passing the SELinux options.

- Properly fixed the LSM/SELinux/SCTP hooks with the addition of the
security_sctp_assoc_established() hook.  This work was done in
conjunction with the netdev folks and should complete the move of the
SCTP labeling from the endpoints to the associations.

- Fixed a variety of sparse warnings caused by changes in the "__rcu"
markings of some core kernel structures.

- Ensure we access the superblock's LSM security blob using the
stacking-safe accessors.

- Added the ability for the kernel to always allow FIOCLEX and
FIONCLEX if the "ioctl_skip_cloexec" policy capability is specified.

- Various constifications improvements, type casting improvements,
additional return value checks, and dead code/parameter removal.

- Documentation fixes.

Please merge.
-Paul
