rust-fuzzer-gen

Convert libFuzzer fuzz_target! files to Unit Tests #[test] for Rust.

Setup

• Rust nightly

  rustup install nightly
  rustup default nightly

• cargo-fuzz

  cargo install cargo-fuzz

Usage

NOTE The process is subject to change as the project matures.

Getting Repo

mkdir -p data && cd data
git clone https://github.com/marshallpierce/rust-base64
cd ..

Transforming Fuzzers

cargo run data/rust-base64

This step does two things data/rust-base64

1. modify fuzzer files in \fuzz and copy a backup \fuzz-bak
2. generate unit tests \tests-gen based on \fuzz

To restore to previous stage, use rm fuzz tests-gen -rf && mv fuzz-bak fuzz.

Fuzzing with data recorded

cd data/rust-base64
cargo fuzz run roundtrip > record.txt
head record.txt

Using as a package

cargo install --git https://github.com/SecurityLab-UCD/rust-fuzzer-gen.git
