Marcus Meissner (msmeissn) about 2 years ago (revision 154)

- updated to 4.03c
  - Building now gives a build summary what succeeded and what not
  - afl-fuzz:
    - added AFL_NO_STARTUP_CALIBRATION to start fuzzing at once instead
      of calibrating all initial seeds first. Good for large queues
      and long execution times, especially in CIs.
    - default calibration cycles set to 7 from 8, and only add 5 cycles
      to variables queue items instead of 12.
  - afl-cc:
    - fixed off-by-one bug in our pcguard implemenation, thanks for
      @tokatoka for reporting
    - fix for llvm 15 and reenabling LTO, thanks to nikic for the PR!
    - better handling of -fsanitize=..,...,.. lists
    - support added for LLVMFuzzerRunDriver()
    - fix gcc_mode cmplog
    - obtain the map size of a target with setting AFL_DUMP_MAP_SIZE=1
      note that this will exit the target before main()
  - qemu_mode:
    - added AFL_QEMU_TRACK_UNSTABLE to log the addresses of unstable
      edges (together with AFL_DEBUG=1 afl-fuzz). thanks to
      worksbutnottested!
  - afl-analyze broke at some point, fix by CodeLogicError, thank you!
  - afl-cmin/afl-cmin.bash now have an -A option to allow also crashing
    and timeout inputs
  - unicorn_mode:
    - updated upstream unicorn version
    - fixed builds for aarch64
    - build now uses all available cores

- updated to 4.02c
  - afl-cc:
    - important fix for the default pcguard mode when LLVM IR vector
      selects are produced, thanks to @juppytt for reporting!
  - gcc_plugin:
    -   Adacore submitted CMPLOG support to the gcc_plugin! :-)
  - llvm_mode:
    -   laf cmp splitting fixed for more comparison types
  - frida_mode:
    -   now works on Android!
  - afl-fuzz:
    - change post_process hook to allow returning NULL and 0 length to
      tell afl-fuzz to skip this mutated input

Marcus Meissner (msmeissn) over 2 years ago (revision 150)

- 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+

Aaron Puchert (aaronpuchert) over 2 years ago (revision 146)

- Fix build with armv7l on Leap: we have afl-llvm-rt-lto{,-32}.o.
- Fix build with ppc64le: we don't seem to have the 32-bit object
  files available there and there is also no gcc-32bit.

Marcus Meissner (msmeissn) almost 3 years ago (revision 145)

- updated to 4.00c
  - complete documentation restructuring, made possible by Google Season
    of Docs :) thank you Jana!
  - we renamed several UI and fuzzer_stat entries to be more precise,
    e.g. "unique crashes" -> "saved crashes", "total paths" ->
    "corpus count", "current path" -> "current item".
    This might need changing custom scripting!
  - Nyx mode (full system emulation with snapshot capability) has been
    added - thanks to @schumilo and @eqv!
  - unicorn_mode:
    -   Moved to unicorn2! by Ziqiao Kong (@lazymio)
    -   Faster, more accurate emulation (newer QEMU base), risc-v support
    -   removed indirections in rust callbacks
  - new binary-only fuzzing mode: coresight_mode for aarch64 CPUs :)
    thanks to RICSecLab submitting!
  - if instrumented libaries are dlopen()'ed after the forkserver you
    will now see a crash. Before you would have colliding coverage.
    We changed this to force fixing a broken setup rather then allowing
    ineffective fuzzing.
  - See docs/best_practices.md how to fix such setups.
  - afl-fuzz:
    -   cmplog binaries will need to be recompiled for this version
        (it is better!)
    -   fix a regression introduced in 3.10 that resulted in less
        coverage being detected. thanks to Collin May for reporting!
    -   ensure all spawned targets are killed on exit
    -   added AFL_IGNORE_PROBLEMS, plus checks to identify and abort on
        incorrect LTO usage setups and enhanced the READMEs for better
        information on how to deal with instrumenting libraries
    -   fix -n dumb mode (nobody should use this mode though)
