[LSC] Add LOCAL_LICENSE_KINDS to external/rust/crates/libfuzzer-sys am: 276f901c04 am: 31b9bb6b3b am: f15f241abf Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/libfuzzer-sys/+/1588729 MUST ONLY BE SUBMITTED BY AUTOMERGER Change-Id: Ic9a0f6447dda760b778b6bd225d6f33d4370a3a1
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 = "0.3.0" 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' \ -Z sanitizer=address
And finally, run the fuzzer:
$ ./target/debug/fuzzed
./update-libfuzzer.sh <github.com/llvm-mirror/llvm-project SHA1>
