Subject: [PATCH 0/3] kunit: fix a UAF bug and do some optimization
Date: Wed, 9 Mar 2022 01:47:02 +0000 [thread overview]
Message-ID: <20220309014705.1265861-1-liupeng256@huawei.com> (raw)
This series is to fix UAF when running kfence test case test_gfpzero,
which is time costly. This UAF bug can be easily triggered by setting
CONFIG_KFENCE_DYNAMIC_OBJECTS = 65535. Furthermore, some optimization
for kunit tests has been done.
