American fuzzy lop is a security-oriented fuzzer
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.

Revision 82 (latest revision is 83)
- updated to 4.20c + A new forkserver communication model is now introduced. afl-fuzz is backward compatible to old compiled targets if they are not built for CMPLOG/Redqueen, but new compiled targets will not work with old afl-fuzz versions! + Recompile all targets that are instrumented for CMPLOG/Redqueen! - AFL++ now supports up to 4 billion coverage edges, up from 6 million. - New compile option: `make PERFORMANCE=1` - this will enable special CPU dependent optimizations that make everything more performant - but the binaries will likely won't work on different platforms. Also enables a faster hasher if the CPU requirements are met. - The persistent record feature (see config.h) was expanded to also support replay, thanks to @quarta-qti ! - afl-fuzz: - the new deterministic fuzzing feature is now activated by default, deactivate with -z. Parameters -d and -D are ignored. - small improvements to CMPLOG/redqueen - workround for a bug with MOpt -L when used with -M - in the future we will either remove or rewrite MOpt. - fix for `-t xxx+` feature - -e extension option now saves the queue items, crashes, etc. with the extension too - fixes for trimmming, correct -V time and reading stats on resume by eqv thanks a lot! - afl-cc: - added collision free caller instrumentation to LTO mode. activate with `AFL_LLVM_LTO_CALLER=1`. You can set a max depth to go through single block functions with `AFL_LLVM_LTO_CALLER_DEPTH` (default 0) - fixes for COMPCOV/LAF and most other modules - fix for GCC_PLUGIN cmplog that broke on std::strings (forwarded request 1167801 from msmeissn)
