2020-10-29	selftests/lkdtm: Use "comm" instead of "diff" for dmesg	Kees Cook
	[ Upstream commit d00451c8118f8f7ab8e057bc6ee2f8b7d70b6a1c ] Instead of full GNU diff (which smaller boot environments may not have), use "comm" which is more available.

2020-08-19	selftests/lkdtm: Reset WARN_ONCE to avoid false negatives	Kees Cook
	[ Upstream commit 4fccc8c0ff740e62343b6de38426a48b345b95f4 ] Since we expect to see warnings every time for many tests, just reset the WARN_ONCE flags each time the script runs.

2020-05-08	selftests/lkdtm: Don't clear dmesg when running tests	Michael Ellerman
	It is Very Rude to clear dmesg in test scripts. That's because the script may be part of a larger test run, and clearing dmesg potentially destroys the output of other tests. We can avoid using dmesg -c by saving the content of dmesg before the test, and then using diff to compare that to the dmesg afterward, producing a log with just the added lines.

2020-01-10	selftests/lkdtm: Add tests for LKDTM targets	Kees Cook
	This adds a basic framework for running all the "safe" LKDTM tests. This will allow easy introspection into any selftest logs to examine the results of most LKDTM tests. Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
