Hi Linus, Please pull these changes for v5.2-rc1. This is effectively part of my gcc-plugins tree, but as this adds some Clang support, it felt weird to still call it "gcc-plugins". :) This consolidates Kconfig for the existing stack variable initialization (via structleak and stackleak gcc plugins) and adds Alexander Potapenko's support for Clang's new similar functionality.
Thanks! -Kees The following changes since commit 8c2ffd9174779014c3fe1f96d9dc3641d9175f00: Linux 5.1-rc2 (2019-03-24 14:02:26 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git tags/meminit-v5.2-rc1 for you to fetch changes up to 709a972efb01efaeb97cad1adc87fe400119c8ab: security: Implement Clang's stack initialization (2019-04-24 14:00:56 -0700) ---------------------------------------------------------------- compiler-based memory initialization - Consolidate memory initialization Kconfigs (Kees) - Implement support for Clang's stack variable auto-init (Alexander) ---------------------------------------------------------------- Kees Cook (3): security: Create "kernel hardening" config area security: Move stackleak config to Kconfig.hardening security: Implement Clang's stack initialization Makefile | 5 ++ scripts/gcc-plugins/Kconfig | 126 ++-------------------------------- security/Kconfig | 2 + security/Kconfig.hardening | 164 ++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 177 insertions(+), 120 deletions(-) create mode 100644 security/Kconfig.hardening -- Kees Cook
