TODO list for AFL++

Roadmap 2.67+

  • expand on AFL_LLVM_INSTRUMENT_FILE to also support sancov allowlist format
  • AFL_MAP_SIZE for qemu_mode and unicorn_mode
  • CPU affinity for many cores? There seems to be an issue > 96 cores

Further down the road

afl-fuzz:

  • setting min_len/max_len/start_offset/end_offset limits for mutation output

llvm_mode:

  • LTO - imitate sancov

gcc_plugin:

  • (wait for submission then decide)
  • laf-intel
  • better instrumentation (seems to be better with gcc-9+)

better documentation:

  • flow graph
  • short intro
  • faq (how to increase stability, speed, many parallel ...)

qemu_mode:

  • update to 5.x (if the performance bug if gone)
  • non colliding instrumentation
  • rename qemu specific envs to AFL_QEMU (AFL_ENTRYPOINT, AFL_CODE_START/END, AFL_COMPCOV_LEVEL?)
  • add AFL_QEMU_EXITPOINT (maybe multiple?), maybe pointless as we have persistent mode
  • add/implement AFL_QEMU_INST_LIBLIST and AFL_QEMU_NOINST_PROGRAM
  • add/implement AFL_QEMU_INST_REGIONS as a list of _START/_END addresses
