[GIT PULL] SELinux patches for v5.4

[Paul Moore]

Hi Linus,

Eight SELinux patches for v5.4, the highlights are listed below and
all pass the selinux-testsuite, please merge for v5.4.

- Add LSM hooks, and SELinux access control hooks, for dnotify,
fanotify, and inotify watches.  This has been discussed with both the
LSM and fs/notify folks and everybody is good with these new hooks.

- The LSM stacking changes missed a few calls to current_security() in
the SELinux code; we fix those and remove current_security() for good.

- Improve our network object labeling cache so that we always return
the object's label, even when under memory pressure.  Previously we
would return an error if we couldn't allocate a new cache entry, now
we always return the label even if we can't create a new cache entry
for it.

- Convert the sidtab atomic_t counter to a normal u32 with
READ/WRITE_ONCE() and memory barrier protection.

- A few patches to policydb.c to clean things up (remove forward
declarations, long lines, bad variable names, etc.).

Thanks,
-Paul
