American fuzzy lop is a security-oriented fuzzer that employs a novel type of compile-time instrumentation and genetic algorithms to automatically discover clean, interesting test cases that trigger new internal states in the targeted binary. This substantially improves the functional coverage for the fuzzed code. The compact synthesized corpora produced by the tool are also useful for seeding other, more labor- or resource-intensive testing regimes down the road.

Compared to other instrumented fuzzers, afl-fuzz is designed to be practical: it has modest performance overhead, uses a variety of highly effective fuzzing strategies and effort minimization tricks, requires essentially no configuration, and seamlessly handles complex, real-world use cases - say, common image parsing or file compression libraries.

- updated to 4.01c
  - fixed */build_...sh scripts to work outside of git
  - new custom_mutator: libafl with token fuzzing :)
  - afl-fuzz:
    - when you just want to compile once and set CMPLOG, then just
      set -c 0 to tell afl-fuzz that the fuzzing binary is also for
      CMPLOG.
    - new commandline options -g/G to set min/max length of generated
      fuzz inputs
    - you can set the time for syncing to other fuzzer now with
      AFL_SYNC_TIME
    - reintroduced AFL_PERSISTENT and AFL_DEFER_FORKSRV to allow
      persistent mode and manual forkserver support if these are not
      in the target binary (e.g. are in a shared library)
    - add AFL_EARLY_FORKSERVER to install the forkserver as earliest as
      possible in the target (for afl-gcc-fast/afl-clang-fast/
      afl-clang-lto)
    - "saved timeouts" was wrong information, timeouts are still thrown
      away by default even if they have new coverage (hangs are always
      kept), unless AFL_KEEP_TIMEOUTS are set
    - AFL never implemented auto token inserts (but user token inserts,
      user token overwrite and auto token overwrite), added now!
    - fixed a mutation type in havoc mode
    - Mopt fix to always select the correct algorithm
    - fix effector map calculation (deterministic mode)
    - fix custom mutator post_process functionality
    - document and auto-activate pizza mode on condition
  - afl-cc:
    - due a bug in lld of llvm 15 LTO instrumentation wont work atm :-(
    - converted all passed to use the new llvm pass manager for llvm 11+
