AFL Fuzzing scripts

To use these, you need to install afl (of course), and xterm. A tiling window manager helps manage many concurrent fuzzer instances.

Note, afl sometimes requires system configuration, if you find AFL quitting prematurely, try manually launching it and addressing any error messages.

Fuzz the parser

$ sh ./tools/afl/prepare_to_fuzz.sh
$ export NFUZZ=1
$ sh ./tools/afl/fuzz.sh parser
Ctrl+C when done to close all fuzzer terminals.
$ sh ./tools/afl/aggregate_cases.sh parser
$ ls ./fuzz_out/parser_aggregated/

Fuzz the unmarshaller

$ janet ./tools/afl/generate_unmarshal_testcases.janet
$ sh ./tools/afl/prepare_to_fuzz.sh
$ export NFUZZ=1
$ sh ./tools/afl/fuzz.sh unmarshal
Ctrl+C when done to close all fuzzer terminals.
$ sh ./tools/afl/aggregate_cases.sh unmarshal
$ ls ./fuzz_out/unmarshal_aggregated/
