Subject: [PATCH v3 0/6] ubsan: Split out bounds checker
Date: Wed, 15 Jan 2020 17:23:15 -0800 [thread overview]
Message-ID: <20200116012321.26254-1-keescook@chromium.org> (raw)
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),
and adjusts ubsan and kasan slightly for correct panic handling.
-Kees
v3:
- use UBSAN menuconfig (will)
- clean up ubsan report titles (dvyukov)
- fix ubsan/kasan "panic" handling
- add Acks
v2: https://lore.kernel.org/lkml/20191121181519.28637-1-keescook@chromium.org
v1: https://lore.kernel.org/lkml/20191120010636.27368-1-keescook@chromium.org
Kees Cook (6):
ubsan: Add trap instrumentation option
ubsan: Split "bounds" checker from other options
lkdtm/bugs: Add arithmetic overflow and array bounds checks
ubsan: Check panic_on_warn
kasan: Unset panic_on_warn before calling panic()
ubsan: Include bug type in report header
