descriptionLow-level bolts to create fuzzers and so much more
AFLplusplus (aflpp)



LibAFL_bolts: OS and Fuzzer Dev's Libary Collection.

LibAFL logo

The libafl_bolts crate exposes a lot of low-level features of LibAFL for projects that are unrelated to fuzzing, or just fuzzers completely different to LibAFL. Some cross-platform things in bolts include (but are not limited to):

  • SerdeAnyMap: a map that stores and retrieves elements by type and is serializable and deserializable
  • ShMem: A cross-platform (Windows, Linux, Android, MacOS) shared memory implementation
  • LLMP: A fast, lock-free IPC mechanism via SharedMap
  • Core_affinity: A maintained version of core_affinity that can be used to get core information and bind processes to cores
  • Rands: Fast random number generators for fuzzing (like RomuRand)
  • MiniBSOD: get and print information about the current process state including important registers.
  • Tuples: Haskel-like compile-time tuple lists
  • Os: OS specific stuff like signal handling, windows exception handling, pipes, and helpers for fork

For bugs, feel free to open issues or contact us directly. Thank you for your support. <3

Even though we will gladly assist you in finishing up your PR, try to

  • keep all the crates compiling with stable rust (hide the eventual non-stable code under cfgs)
  • run cargo nightly fmt on your code before pushing
  • check the output of cargo clippy --all or ./
  • run cargo build --no-default-features to check for no_std compatibility (and possibly add #[cfg(feature = "std")]) to hide parts of your code.

Some of the parts in this list may be hard, don't be afraid to open a PR if you cannot fix them by yourself, so we can help.
