Subject: [PATCH 0/3] ubsan: Split out bounds checker
Date: Tue, 19 Nov 2019 17:06:33 -0800 [thread overview]
Message-ID: <20191120010636.27368-1-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.
