How to set up syzkaller

Generic setup instructions for fuzzing Linux kernel are outlined here. For other OS kernels check: Akaros, FreeBSD, Fuchsia, NetBSD, OpenBSD, Windows.

After following these instructions you should be able to run syz-manager, see it executing programs and be able to access statistics exposed at http://127.0.0.1:56741:

$ ./bin/syz-manager -config=my.cfg

2017/06/14 16:40:35 executed 15504, cover 132403, crashes 0, repro 0

At this point it's important to ensure that syzkaller is able to collect code coverage of the executed programs (unless you specified "cover": false in the config or coverage is not yet supported for the kernel you're fuzzing). The cover counter on the web page should be non zero.

More information on the configuration file format is available here.
