Hi Linus, Please pull these gcc-plugin changes for v5.1-rc1. This adds additional type coverage to the existing structleak plugin and adds a large set of selftests to help evaluate stack variable zero-initialization coverage (which can be used to test whatever instrumentation might be performing zero-initialization: either with the structleak plugin or with Clang's coming "-ftrivial-auto-var-init=zero" option).
Note that there is a minor conflict seen in linux-next with KASAN changes in -mm, which removes the !KASAN_EXTRA depends from structleak. sfr's resolution is correct: https://lkml.kernel.org/r/[email protected] Thanks! -Kees The following changes since commit 49a57857aeea06ca831043acbb0fa5e0f50602fd: Linux 5.0-rc3 (2019-01-21 13:14:44 +1300) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git tags/gcc-plugins-v5.1-rc1 for you to fetch changes up to 50ceaa95ea09703722b30b4afa617c972071cd7f: lib: Introduce test_stackinit module (2019-03-04 09:29:52 -0800) ---------------------------------------------------------------- increased structleak coverage - And scalar and array initialization coverage - Refactor Kconfig to make options more clear - Add self-test module for testing automatic initialization ---------------------------------------------------------------- Kees Cook (2): gcc-plugins: structleak: Generalize to all variable types lib: Introduce test_stackinit module lib/Kconfig.debug | 10 + lib/Makefile | 1 + lib/test_stackinit.c | 378 ++++++++++++++++++++++++++++++++ scripts/Makefile.gcc-plugins | 2 + scripts/gcc-plugins/Kconfig | 58 ++++- scripts/gcc-plugins/structleak_plugin.c | 36 ++- 6 files changed, 463 insertions(+), 22 deletions(-) create mode 100644 lib/test_stackinit.c -- Kees Cook
