Merge tag 'selinux-pr-20180530' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux

Pull SELinux fix from Paul Moore:
 "One more small fix for SELinux: a small string length fix found by
  KASAN.

  I dislike sending patches this late in the release cycle, but this
  patch fixes a legitimate problem, is very small, limited in scope, and
  well understood.

  There are two threads with more information on the problem, the latest
  is linked below:

    https://marc.info/?t=152723737400001&r=1&w=2

  Stephen points out in the thread linked above:

   'Such a setxattr() call can only be performed by a process with
    CAP_MAC_ADMIN that is also allowed mac_admin permission in SELinux
    policy. Consequently, this is never possible on Android (no process
    is allowed mac_admin permission, always enforcing) and is only
    possible in Fedora/RHEL for a few domains (if enforcing)'"

e9d33f149f selftests/intel_pstate: Improve test, minor fixes
A few changes improve the overall usability of the test:
* fix a hard-coded maximum frequency (3300),
* don't adjust the CPU frequency if only evaluating results,
* fix a comparison for multiple frequencies.

A symptom of that last issue looked like this:
  ./run.sh: line 107: [: too many arguments
  ./run.sh: line 110: 3099
  3099
  3100-3100: syntax error in expression (error token is \"3099
  3100-3100\")

Because a check will count how many differente frequencies
there are among the CPUs of the system, and after they are
tallied another read is performed, which might produce
different results.

84092dbcf9 selftests: cgroup: add memory controller self-tests
Cgroups are used for controlling the physical resource distribution
(memory, CPU, io, etc) and often are used as basic building blocks
for large distributed computing systems. Even small differences
in the actual behavior may lead to significant incidents.

The codebase is under the active development, which will unlikely
stop at any time soon. Also it's scattered over different kernel
subsystems, which makes regressions more probable.

Given that, the lack of any tests is crying.

This patch implements some basic tests for the memory controller,
as well as a minimal required framework. It doesn't pretend for a
very good coverage, but pretends to be a starting point.

Hopefully, any following significant changes will include corresponding
tests.

Tests for CPU and io controllers, as well as cgroup core
are next in the todo list.

Delete RUN_TESTS and EMIT_TESTS overrides and use common defines in
lib.mk. Common defines work after making the change the test to run
with ratio=2 as the default mode to be able to invoke the test without
the "-r 2" argument from the common RUN_TESTS and EMIT_TESTS.

The run_full_tests target now calls the test with "-r 10".

addee42aaa selftests: mount: delete RUN_TESTS and EMIT_TESTS overrides
Delete RUN_TESTS and EMIT_TESTS overrides and use common defines in
lib.mk. Add new run_tests.sh to do the dependency checks the custom
RUN_TESTS did. Common defines work with the run_tests.sh set as the
TEST_PROGS and defining unprivileged-remount-test in TEST_GEN_FILES.

Kselftest framework builds and installs TEST_GEN_FILES and doesn't run
them via RUN_TESTS and include it in EMIT_TESTS. With this change the
new run_tests.sh runs the test after checking dependencies.

This change also adds Skip handling to return kselftest skip code when
test is skipped to clearly identify when the test is skipped instead of
reporting it as failed.

Output with this change:

TAP version 13
selftests: mount: run_tests.sh
========================================
WARN: No /proc/self/uid_map exist, test skipped.

3c07aaef65 selftests: kselftest: change KSFT_SKIP=4 instead of KSFT_PASS
KSFT_SKIP points to KSFT_PASS resulting in reporting skipped tests as
Passed, when test programs exit with KSFT_SKIP or call ksft_exit_skip().
If tests are skipped because of unmet dependencies and/or unsupported
configuration, reporting them as passed leads to too many false positives.

Fix it to return a skip code of 4 to clearly differentiate the skipped
tests.
