libfuzzer-sys
CrateBarebones wrapper around LLVM's libFuzzer runtime library.
The CPP parts are extracted from compiler-rt git repository with git filter-branch
.
libFuzzer relies on LLVM sanitizer support. The Rust compiler has built-in support for LLVM sanitizer support, for now, it's limited to Linux. As a result, libfuzzer-sys
only works on Linux.
cargo fuzz
!The recommended way to use this crate with cargo fuzz
!.
This crate can also be used manually as following:
First create a new cargo project:
$ cargo new --bin fuzzed $ cd fuzzed
Then add a dependency on the fuzzer-sys
crate and your own crate:
[dependencies] libfuzzer-sys = "0.4.0" your_crate = { path = "../path/to/your/crate" }
Change the fuzzed/src/main.rs
to fuzz your code:
#![no_main] use libfuzzer_sys::fuzz_target; fuzz_target!(|data: &[u8]| { // code to fuzz goes here });
Build by running the following command:
$ cargo rustc -- \ -C passes='sancov' \ -C llvm-args='-sanitizer-coverage-level=3' \ -C llvm-args='-sanitizer-coverage-inline-8bit-counters' \ -Z sanitizer=address
And finally, run the fuzzer:
$ ./target/debug/fuzzed
./update-libfuzzer.sh <github.com/llvm-mirror/llvm-project SHA1>
