-Fuzzers
-=======
-
-This directory contains a collection of fuzzing tools. Each tests a different
-entry point to the code.
-
-Usage notes:
-
-1. Install AFL:
-
- .. code::
-
- apt-get install afl
-
-2. Build the fuzzers:
-
- .. code::
-
- make fuzzers
-
-3. Some of the tests (eg ``fuzz_decrypt`` and ``fuzz_group_decrypt``) require a
- session file. You can create one by pickling an Olm session.
-
-4. Make some work directories:
-
- .. code::
-
- mkdir -p fuzzing/in fuzzing/out
-
-5. Generate starting input:
-
- .. code::
-
- echo "Test" > fuzzing/in/test
-
-6. Run the test under ``afl-fuzz``:
-
- .. code::
-
- afl-fuzz -i fuzzing/in -o fuzzing/out -- \
- ./build/fuzzers/fuzz_<fuzzing_tool> [<test args>]
-
-7. To resume with the data produced by an earlier run:
-
- .. code::
-
- afl-fuzz -i- -o existing_output_dir [...etc...]
-
-8. If it shows failures, pipe the failure case into
- ``./build/fuzzers/debug_<fuzzing_tool>``, fix, and repeat.
