Fuzzing FreeBSD w/ AFL
======================

This project is used to store the various information and scripts that
I have used in fuzzing FreeBSD.

This project started when someone reported that fsck_ffs couldn't
repair a file system they had, but as we all know, file systems are
often large, and contain data the people don't want to share, making
getting test cases more difficult than most.  I decided to see if
fuzzing was able to reproduce their failure, and the very first
failure was the reported, but it also managed to find some more.

Building
--------

There is a script `build.sh` that will set the compiler correctly when
building parts of the FreeBSD source tree.  You do have to be careful
when doing this as there are sometimes dependencies that need to be
built as well, e.g. `libufs` for `fsck_ffs`.
