[Xen-devel] [PATCH 0/4] fuzz: basic AFL support

[Wei Liu <wei.liu2@xxxxxxxxxx>]

Provide simple stub programs for AFL fuzzer. For usage, please see README.afl.

This series doesn't aim to improve fuzzing targets. It is just demonstration
for how we could use the same fuzzing code for both oss-fuzz and AFL.

The stub programs are identical in libefl and x86 emulator at the moment, but
they will likely diverge in the future. The duplication of code is deliberate.

Julien, FYI I think the in-tree libfdt could have something similar, too.

Wei.
