These are fuzzing targets for fuzzing orion.
Fuzzing is done using honggfuzz-rs.
To start fuzzing, you must install the same version of honggfuzz as the one specified in the Cargo.toml:
cargo install --force honggfuzz --vers 0.5.51
By default, the master branch of orion is used for fuzzing. If another version needs to be fuzzed, specify the version
in the Cargo.toml accordingly.
Some fuzzing targets use sodiumoxide to cross-verify results. Any target that uses sodiumoxide requires libsodium to be installed on the system as well.
To fuzz with ASan (with ODR violation detection turned off):
RUSTFLAGS="-Z sanitizer=address" ASAN_OPTIONS="detect_odr_violation=0" cargo +nightly hfuzz run aead
To fuzz with LeakSanitizer:
RUSTFLAGS="-Z sanitizer=leak" cargo +nightly hfuzz run aead
Some of the targets do some heavy processing, so specifying the timeout can be required:
RUSTFLAGS="-Z sanitizer=address" ASAN_OPTIONS="detect_odr_violation=0" HFUZZ_RUN_ARGS="-t 30" cargo +nightly hfuzz run aead
where -t 30 is in seconds.
All the above examples run the aead target. This can be any fuzzing target in src/ that is not util.
HFUZZ_RUN_ARGS="--minimize" cargo hfuzz run aead
