2022-02-14	fortify: Update compile-time tests for Clang 14	Kees Cook	1	-2/+6
	Clang 14 introduces support for compiletime_assert(). Update the compile-time warning regex to catch Clang's variant of the warning text in preparation for Clang supporting CONFIG_FORTIFY_SOURCE.

2021-10-18	fortify: Add compile-time FORTIFY_SOURCE tests	Kees Cook	1	-0/+62
	While the run-time testing of FORTIFY_SOURCE is already present in LKDTM, there is no testing of the expected compile-time detections. In preparation for correctly supporting FORTIFY_SOURCE under Clang, adding additional FORTIFY_SOURCE defenses, and making sure FORTIFY_SOURCE doesn't silently regress with GCC, introduce a build-time test suite that checks each expected compile-time failure condition. As this is relatively backwards from standard build rules in the sense that a successful test is actually a compile _failure_, create a wrapper script to check for the correct errors, and wire it up as a dummy dependency to lib/string.o, collecting the results into a log file artifact.
