Subject: [PATCH v2 0/3] ubsan: Split out bounds checker
v2:
- clarify Kconfig help text (aryabinin)
- add reviewed-by
- aim series at akpm, which seems to be where ubsan goes through?
v1: https://lore.kernel.org/lkml/20191120010636.27368-1-keescook@chromium.org
This splits out the bounds checker so it can be individually used. This
is expected to be enabled in Android and hopefully for syzbot. Includes
LKDTM tests for behavioral corner-cases (beyond just the bounds checker).

Kees Cook (3):
ubsan: Add trap instrumentation option
ubsan: Split "bounds" checker from other options
lkdtm/bugs: Add arithmetic overflow and array bounds checks
