Subject: [PATCH RFC 0/3] kcov: collect coverage from usb and vhost
Date: Thu, 17 Oct 2019 19:44:12 +0200 [thread overview]
Message-ID: <cover.1571333592.git.andreyknvl@google.com> (raw)
This patchset extends kcov to allow collecting coverage from the USB
subsystem and vhost workers. See the first patch description for details
about the kcov extension. The other two patches apply this kcov extension
to USB and vhost.
These patches have been used to enable coverage-guided USB fuzzing with
syzkaller for the last few years, see the details here:
https://github.com/google/syzkaller/blob/master/docs/linux/external_fuzzing_usb.md
