Work in progress continuous fuzzing infrastructure. Mainly build and maintained to continuously fuzz Bitcoin Core but support for adding and fuzzing other projects is available (see projects/).

docker build --tag fuzzor-base:latest --file infra/Dockerfile.base .

cd projects/bitcoin
docker build --tag fuzzor-bitcoin:latest .

docker run -it fuzzor-bitcoin:latest

FUZZ=txgraph ./out/libfuzzer_asan/fuzz

• Automatic bug reports
• Automatic coverage report creation
• Support for major fuzzing engines (AFL++, libFuzzer, honggfuzz, Native Golang)
• Crash deduplication
• Corpus minimization with all supported engines
• Real-time ensemble fuzzing
• Coverage based campaign scheduling
• Support for experimental fuzzing engines (e.g. fuzz driven characterization testing with SemSan)

• Support for more fuzzing engines (e.g. Radamsa, libafl_libfuzzer, libafl-fuzz, ...)
• Snapshot fuzzing support (e.g. using full-system libafl_qemu and/or nyx)
• Concolic fuzzing engine support
• Automatic bug triaging
• Automatic pull request fuzzing

CI is self-hosted on AWS with RunsOn.
