Paul Moore 4c0ddc8712 selinux: add proper NULL termination to the secclass_map permissions 
commit e4c82eafb609c2badc56f4e11bc50fcf44b8e9eb upstream.

This patch adds the missing NULL termination to the "bpf" and
"perf_event" object class permission lists.

This missing NULL termination should really only affect the tools
under scripts/selinux, with the most important being genheaders.c,
although in practice this has not been an issue on any of my dev/test
systems.  If the problem were to manifest itself it would likely
result in bogus permissions added to the end of the object class;
thankfully with no access control checks using these bogus
permissions and no policies defining these permissions the impact
would likely be limited to some noise about undefined permissions
during policy load.

Fixes: ec27c3568a ("selinux: bpf: Add selinux check for eBPF syscall operations")
Fixes: da97e18458 ("perf_event: Add support for LSM and SELinux checks")

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
