Build

mkdir build && cd build
# Without custom mutator (libfuzzer modify the buffer randomly)
cmake ..
# TODO: TBC. `wasm-tools mutate` is not supported yet
# With custom mutator (wasm-tools mutate)
cmake .. -DCUSTOM_MUTATOR=1
make -j$(nproc)

Manually generate wasm file in build

# wasm-tools smith generate some valid wasm file
# The generated wasm file is in corpus_dir under build
# N - Number of files to be generated
./smith_wasm.sh N 

# running

bash cd build ./wasm-mutate-fuzz CORPUS_DIR


## Fuzzing Server

shell

  1. Installation Dependent Environment $ cd server $ pip install -r requirements.txt

  2. Database Migration $ python3 app/manager.py db init $ python3 app/manager.py db migrate
    $ python3 app/manager.py db upgrade

  3. Change localhost to your machine's IP address $ cd ../portal $ vim .env # Change localhost to your machine's IP address # http://:16667

  4. Run Server and Portal $ cd .. # Switch to the original directory If you want to customize the front-end deployment port: # defaut 9999 $ vim .env # Please change the portal_port to the port you want to use

  5. The server is deployed on port 16667 by default, If you want to change the server deployment port:

    $ vim .env # Please change the server_port to the port you want to use 
    $ vim portal/.env # Please change the VITE_SERVER_URL to the port you want to use  # http://ip:<port>
    

    If your network needs to set up a proxy

    $ vim .env # Change proxy to your proxy address
    

    $ docker-compose up --build -d Wait for completion, Access the port set by env ```
