0.4.6
Released 2023-01-26.
Fixed
- Fixed a potential name conflict in functions generated by the
fuzz_target!macro. - Fixed potential stale builds when updating custom libfuzzers to link against.
0.4.5
Released 2022-10-18.
Added
- Added the ability to tell libfuzzer whether to keep files inputs in the corpus
or not. See the
Corpustype and extended documentation for thefuzz_target!macro for details.
Changed
- Ensured that there is always at least one inline-never frame on the stack per fuzz target. This helps prevent oss-fuzz from "deduplicating" different bugs from different fuzz targets into the same bug.
0.4.4
Released 2022-09-01.
Changed
- Updated to
libFuzzercommitdf90d22(release/15.x). - LLVM 16's upcoming change to build requirements to C++17
necessitate reflecting those changes. (
libFuzzerupdates contain C++14 code) - Drastically reduce build times by using parallel C++ compilation jobs
- Updated
randdependency from 0.8.3 to 0.8.5 - Updated
flate2dependency from 1.0.20 to 1.0.24
0.4.3
Released 2020-03-03.
Changed
- Updated to
libFuzzercommit60e32a1.
Fixed
- Fixed an issue where the
fuzz_target!macro would sometimes expand to versions of itself that were not$crateprefixed and would result in "error: cannot find macrofuzz_targetin this scope" if the caller didn't import the macro but used the qualified version of it instead.
0.4.2
Released 2020-05-26.
Changed
- Improved performance of checking for whether
cargo fuzzis requesting thestd::fmt::Debugoutput of an input or not. This is always false during regular fuzzing, so making this check faster should give slightly better fuzzing throughput.
0.4.1
Released 2020-05-13.
Added
- Added support for defining custom mutators. See the documentation for the
fuzz_mutator!macro for details.
Changed
- Upgraded libfuzzer to llvm/llvm-project's 70cbc6d.
0.4.0
Released 2021-02-24.
Changed
- The public
arbitrarydependency was updated to version 1.0.
0.3.5
Released 2020-11-18.
Changed
0.3.4
Released 2020-08-22.
Changed
- Updated
arbitrarydependency to 0.4.6
0.3.3
Released 2020-07-27.
Changed
-
Upgraded libfuzzer to commit 4a4cafa.
Notably, this pulls in the new Entropic engine for libFuzzer, which should boost fuzzing efficiency when enabled. You can enable Entropic by passing
-entropic=1to your built fuzz targets (although, note that it is still labeled "experimental").
0.3.2
Released 2020-03-18.
Changed
- Upgraded the
arbitrarydependency re-export to version 0.4.1.
0.3.1
Released 2020-02-27.
Changed
- Fixed a fuzzing performance issue where libfuzzer could unnecessarily spend
time exploring all the ways that an
Arbitraryimplementation could fail to construct an instance of itself because the fuzzer provided too few bytes. See https://github.com/rust-fuzz/libfuzzer/issues/59 for details.
0.3.0
Released 2019-01-22.
Changed
- Now works with and re-exports
arbitraryversions 0.4.x.
0.2.1
Released 2019-01-16.
Added
- Added support for the
CUSTOM_LIBFUZZER_STD_CXX=<lib>environment variable during builds that already use a custom libFuzzer checkout withCUSTOM_LIBFUZZER_PATH. This allows you to explicitly choose to link LLVM or GNU C++ standard libraries.
0.2.0
Released 2020-01-14.
Changed
- Using
arbitrary0.3.x now. It is re-exported aslibfuzzer_sys::arbitrary.
Added
- You can enable support for
#[derive(Arbitrary)]with the"arbitrary-derive"cargo feature. This is a synonym for thearbitrarycrate's"derive"cargo feature.
