- updated to 2.67c
- Support for improved afl++ snapshot module:
https://github.com/AFLplusplus/AFL-Snapshot-LKM
- Due to the instrumentation needing more memory, the initial memory sizes
for -m have been increased
- afl-fuzz:
- added -F option to allow -M main fuzzers to sync to foreign fuzzers,
e.g. honggfuzz or libfuzzer
- added -b option to bind to a specific CPU
- eliminated CPU affinity race condition for -S/-M runs
- expanded havoc mode added, on no cycle finds add extra splicing and
MOpt into the mix
- fixed a bug in redqueen for strings and made deterministic with -s
- llvm_mode:
- now supports llvm 12
- support for AFL_LLVM_ALLOWLIST/AFL_LLVM_DENYLIST (previous
AFL_LLVM_WHITELIST and AFL_LLVM_INSTRUMENT_FILE are deprecated and
are matched to AFL_LLVM_ALLOWLIST). The format is compatible to llvm
sancov, and also supports function matching :)
- added neverzero counting to trace-pc/pcgard
- fixes for laf-intel float splitting (thanks to mark-griffin for
reporting)
- fixes for llvm 4.0
- skipping ctors and ifuncs for instrumentation
- LTO: switch default to the dynamic memory map, set AFL_LLVM_MAP_ADDR
for a fixed map address (eg. 0x10000)
- LTO: improved stability for persistent mode, no other instrumentation
has that advantage
- LTO: fixed autodict for long strings
- LTO: laf-intel and redqueen/cmplog are now applied at link time (forwarded request 827912 from msmeissn)
