Pull gcc plugin fix from Kees Cook: "Lift gcc test into Kconfig. This is for better behavior when the kernel is built with Clang, reported by Stefan Agner" * tag 'gcc-plugins-v4.19-rc1-fix' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: gcc-plugins: Disable when building under Clang

gcc-plugins: Disable when building under Clang

2018-08-23T17:06:12Z

Prior to doing compiler feature detection in Kconfig, attempts to build GCC plugins with Clang would fail the build, much in the same way missing GCC plugin headers would fail the build. However, now that this logic has been lifted into Kconfig, add an explicit test for GCC (instead of duplicating it in the feature-test script).

gcc-plugins: Clean up the cgraph_create_edge* macros

Drop useless redefinitions of cgraph_create_edge* macros. Drop the unused nest argument. Also support gcc-8, which doesn't have freq argument. Signed-off-by: Alexander Popov Signed-off-by: Kees Cook

gcc-plugins: remove unused GCC_PLUGIN_SUBDIR

2018-07-03T02:27:00Z

GCC_PLUGIN_SUBDIR has never been used. If you really need this in the future, please re-add it then. For now, the code is unused. Remove. 'export HOSTLIBS' is not necessary either. Signed-off-by: Masahiro Yamada Signed-off-by: Kees Cook

gcc-plugins: test plugin support in Kconfig and clean up Makefile

2018-06-11T00:16:22Z

Run scripts/gcc-plugin.sh from Kconfig so that users can enable GCC_PLUGINS only when the compiler supports building plugins. Kconfig defines a new symbol, PLUGIN_HOSTCC. This will contain the compiler (g++ or gcc) used for building plugins, or empty if the plugin can not be supported at all. This allows us to remove all ugly testing in Makefile.gcc-plugins.

kcov: test compiler capability in Kconfig and correct dependency

2018-06-11T00:14:08Z

As Documentation/kbuild/kconfig-language.txt notes, 'select' should be be used with care - it forces a lower limit of another symbol, ignoring the dependency. Currently, KCOV can select GCC_PLUGINS even if arch does not select HAVE_GCC_PLUGINS. This could cause the unmet direct dependency. Now that Kconfig can test compiler capability, let's handle this in a more sophisticated way. There are two ways to enable KCOV; use the compiler that natively supports -fsanitize-coverage=trace-pc, or build the SANCOV plugin if the compiler has ability to build GCC plugins. Hence, the correct dependency for KCOV is: depends on CC_HAS_SANCOV_TRACE_PC || GCC_PLUGINS You do not need to build the SANCOV plugin if the compiler already supports -fsanitize-coverage=trace-pc. Hence, the select should be: select GCC_PLUGIN_SANCOV if !CC_HAS_SANCOV_TRACE_PC With this, GCC_PLUGIN_SANCOV is selected only when necessary, so scripts/Makefile.gcc-plugins can be cleaner. I also cleaned up Kconfig and scripts/Makefile.kcov as well. Signed-off-by: Masahiro Yamada Reviewed-by: Kees Cook

security: convert security hooks to use hlist

2018-03-31T02:18:27Z

This changes security_hook_heads to use hlist_heads instead of the circular doubly-linked list heads. This should cut down the size of the struct by about half. In addition, it allows mutation of the hooks at the tail of the callback list without having to modify the head. The longer-term purpose of this is to enable making the heads read only.

gcc-plugins: Use dynamic initializers

2018-02-06T01:27:46Z

GCC 8 changed the order of some fields and is very picky about ordering in static initializers, so instead just move to dynamic initializers, and drop the redundant already-zero field assignments. Suggested-by: Valdis Kletnieks Signed-off-by: Kees Cook
