brainflow-fuzz

an attempt to fuzz stream write/read

Test cpp harness locally

1. git clone https://github.com/brainflow-dev/brainflow.git

2. mkdir build

3. cd build

4. cmake -DCMAKE_CXX_COMPILER=afl-clang-fast++ ..

5. create Makefile & save

6. Prepare harness.cpp

test_harness: harness.cpp
	afl-clang-fast++ -v harness.cpp $(INC) ./CMakeFiles/BoardController.dir/third_party/ant_neuro/eemagine/sdk/wrapper.cc.o -o harness  $(INCC) $(INCCC) -I../third_party/json/

7. run afl-fuzz with default settings: AFL_AUTORESEUME=1 afl-fuzz -D -L0 -i samples/ -t 80 -o sync_dir -M fuzzer00 -- ./harness @@

Compile the test binary if compiled successfully

1. make test_brain
2. ./test test

Test files against python

1. python -m pip install brainflow
2. run brainflow.py <CRASHER_NAME> script with a sample
3. some files are working on python library, some of them are crashing on cpp

Reproducing id:000016,sig:07,src:000010,time:28990834,execs:64400173,op:MOpt_havoc,rep:8 (576) file

1. This file also crashes cpp one but in python it is acting little bit weird, i couldnt manage to find the right time to analyze it to find out the root cause yet. You have to test this file with full path of brainflow.py for ex: /home/user/brainflow.py id:000016,sig:07,src:000010,time:28990834,execs:64400173,op:MOpt_havoc,rep:8
