XCM Simulator Fuzzer

This project will fuzz-test the XCM simulator. It can catch reachable panics, timeouts as well as integer overflows and underflows.

Install dependencies

cargo install honggfuzz

Run the fuzzer

In this directory, run this command:

cargo hfuzz run xcm-fuzzer

Run a single input

In this directory, run this command:

cargo hfuzz run-debug xcm-fuzzer hfuzz_workspace/xcm-fuzzer/fuzzer_input_file

Generate coverage

In this directory, run these four commands:

RUSTFLAGS="-Zprofile -Ccodegen-units=1 -Copt-level=0 -Clink-dead-code -Coverflow-checks=off -Zpanic_abort_tests -Cpanic=abort" CARGO_INCREMENTAL=0 SKIP_WASM_BUILD=1 CARGO_HOME=./cargo cargo build
../../../target/debug/xcm-fuzzer hfuzz_workspace/xcm-fuzzer/input/
zip -0 ccov.zip `find ../../../target/ \( -name "*.gc*" -o -name "test-*.gc*" \) -print`
grcov ccov.zip -s ../../../ -t html --llvm --branch --ignore-not-existing -o ./coverage

The code coverage will be in ./coverage/index.html.
