Merge tag 'selinux-pr-20200330' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux

Pull SELinux updates from Paul Moore:
 "We've got twenty SELinux patches for the v5.7 merge window, the
  highlights are below:

   - Deprecate setting /sys/fs/selinux/checkreqprot to 1.

     This flag was originally created to deal with legacy userspace and
     the READ_IMPLIES_EXEC personality flag. We changed the default from
     1 to 0 back in Linux v4.4 and now we are taking the next step of
     deprecating it, at some point in the future we will take the final
     step of rejecting 1.

   - Allow kernfs symlinks to inherit the SELinux label of the parent
     directory. In order to preserve backwards compatibility this is
     protected by the genfs_seclabel_symlinks SELinux policy capability.

   - Optimize how we store filename transitions in the kernel, resulting
     in some significant improvements to policy load times.

   - Do a better job calculating our internal hash table sizes which
     resulted in additional policy load improvements and likely general
     SELinux performance improvements as well.

   - Remove the unused initial SIDs (labels) and improve how we handle
     initial SIDs.

   - Enable per-file labeling for the bpf filesystem.

   - Ensure that we properly label NFS v4.2 filesystems to avoid a
     temporary unlabeled condition.

   - Add some missing XFS quota command types to the SELinux quota
     access controls.

   - Fix a problem where we were not updating the seq_file position
     index correctly in selinuxfs.

   - We consolidate some duplicated code into helper functions.

   - A number of list to array conversions.

   - Update Stephen Smalley's email address in MAINTAINERS"

+What:		/sys/fs/selinux/checkreqprot
+Date:		April 2005 (predates git)
+KernelVersion:	2.6.12-rc2 (predates git)
+Contact:	selinux@vger.kernel.org
+Description:
+
+	The selinuxfs "checkreqprot" node allows SELinux to be configured
+	to check the protection requested by userspace for mmap/mprotect
+	calls instead of the actual protection applied by the kernel.
+	This was a compatibility mechanism for legacy userspace and
+	for the READ_IMPLIES_EXEC personality flag.  However, if set to
+	1, it weakens security by allowing mappings to be made executable
+	without authorization by policy.  The default value of checkreqprot
+	at boot was changed starting in Linux v4.4 to 0 (i.e. check the
+	actual protection), and Android and Linux distributions have been
+	explicitly writing a "0" to /sys/fs/selinux/checkreqprot during
+	initialization for some time.  Support for setting checkreqprot to 1
+	will be	removed in a future kernel release, at which point the kernel
+	will always cease using checkreqprot internally and will always
+	check the actual protections being applied upon mmap/mprotect calls.
+	The checkreqprot selinuxfs node will remain for backward compatibility
+	but will discard writes of the "0" value and will reject writes of the
+	"1" value when this mechanism is removed.
