Subject: [PATCH 0/2] Make kcov work properly with KASLR enabled
Date: Sun, 11 Dec 2016 03:50:54 +0300 [thread overview]
Message-ID: <1481417456-28826-1-git-send-email-alex.popov@linux.com> (raw)
If CONFIG_RANDOMIZE_BASE is enabled, kcov currently reports kernel addresses
including the random offset which breaks the coverage-guided fuzzing on x86_64 and
AArch64. Fix that by subtracting kaslr_offset() return value.
