- 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)
