# 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](./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.cpp)
```

# Test files against python
1) `python -m pip install brainflow`
2) run `brainflow.py ` 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`
