- 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

- 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!

- 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) (forwarded request 950196 from msmeissn)

- New selective instrumentation option with __AFL_COVERAGE_* commands
to be placed in the source code.
Check out instrumentation/README.instrument_list.md
- afl-fuzz
- Making AFL_MAP_SIZE (mostly) obsolete - afl-fuzz now learns on
start the target map size
- upgraded cmplog/redqueen: solving for floating point, solving
transformations (e.g. toupper, tolower, to/from hex, xor,
arithmetics, etc.). This is costly hence new command line option
`-l` that sets the intensity (values 1 to 3). Recommended is 2.
- added `AFL_CMPLOG_ONLY_NEW` to not use cmplog on initial seeds
from `-i` or resumes (these have most likely already been done)
- fix crash for very, very fast targets+systems (thanks to mhlakhani
for reporting)
- on restarts (`-i`)/autoresume (AFL_AUTORESUME) the stats are now
reloaded and used, thanks to Vimal Joseph for this patch!
- changed the meaning of '+' of the '-t' option, it now means to
auto-calculate the timeout with the value given being the max
timeout. The original meaning of skipping timeouts instead of
abort is now inherent to the -t option.
- if deterministic mode is active (`-D`, or `-M` without `-d`) then
we sync after every queue entry as this can take very long time
otherwise
- added minimum SYNC_TIME to include/config.h (30 minutes default)
- better detection if a target needs a large shared map

abort is now inherent to the -t option.
- if deterministic mode is active (`-D`, or `-M` without `-d`) then
we sync after every queue entry as this can take very long time
otherwise
- added minimum SYNC_TIME to include/config.h (30 minutes default)
- better detection if a target needs a large shared map
- fix for `-Z`
- fixed a few crashes
OBS-URL: https://build.opensuse.org/package/show/devel:tools/afl?expand=0&rev=125
- updated to 3.0c
- llvm_mode/ and gcc_plugin/ moved to instrumentation/
- examples/ renamed to utils/
- moved libdislocator, libtokencap and qdbi_mode to utils/
- all compilers combined to afl-cc which emulates the previous ones
- afl-llvm/gcc-rt.o merged into afl-compiler-rt.o
- afl-fuzz
- not specifying -M or -S will now auto-set "-S default"
- deterministic fuzzing is now disabled by default and can be enabled with
-D. It is still enabled by default for -M.
- a new seed selection was implemented that uses weighted randoms based on
a schedule performance score, which is much better that the previous
walk the whole queue approach. Select the old mode with -Z (auto enabled
with -M)
- Marcel Boehme submitted a patch that improves all AFFast schedules :)
- the default schedule is now FAST
- memory limits are now disabled by default, set them with -m if required
- rpc.statsd support, for stats and charts, by Edznux, thanks a lot!
- reading testcases from -i now descends into subdirectories
- allow the -x command line option up to 4 times
- loaded extras now have a duplication protection
- If test cases are too large we do a partial read on the maximum
supported size
- longer seeds with the same trace information will now be ignored
for fuzzing but still be used for splicing
- crashing seeds are now not prohibiting a run anymore but are
skipped - they are used for splicing, though
- update MOpt for expanded havoc modes
- setting the env var AFL_NO_AUTODICT will not load an LTO autodictionary
- added NO_SPLICING compile option and makefile define (forwarded request 855999 from msmeissn)

- 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)

AFL_LLVM_INSTRUMENT_FILE and AFL_GCC_INSTRUMENT_FILE
- warn on deprecated environment variables
- afl-fuzz:
- -S secondary nodes now only sync from the main node to increase
performance, the -M main node still syncs from everyone. Added checks
that ensure exactly one main node is present and warn otherwise
- Add -D after -S to force a secondary to perform deterministic fuzzing
- If no main node is present at a sync one secondary node automatically
becomes a temporary main node until a real main nodes shows up
- Fixed a mayor performance issue we inherited from AFLfast
- switched murmur2 hashing and random() for xxh3 and xoshiro256**,
resulting in an up to 5.5% speed increase
- Resizing the window does not crash afl-fuzz anymore
- Ensure that the targets are killed on exit
- fix/update to MOpt (thanks to arnow117)
- added MOpt dictionary support from repo
- added experimental SEEK power schedule. It is EXPLORE with ignoring
the runtime and less focus on the length of the test case
- llvm_mode:
- the default instrumentation is now PCGUARD if the llvm version is >= 7,
as it is faster and provides better coverage. The original afl
instrumentation can be set via AFL_LLVM_INSTRUMENT=AFL. This is
automatically done when the instrument_file list feature is used.
- PCGUARD mode is now even better because we made it collision free - plus
it has a fixed map size, so it is also faster! :)
- some targets want a ld variant for LD that is not gcc/clang but ld,
added afl-ld-lto to solve this
- lowered minimum required llvm version to 3.4 (except LLVMInsTrim, which (forwarded request 818318 from msmeissn)

- afl-fuzz:
- AFL_MAP_SIZE was not working correctly
- better python detection
- an old, old bug in afl that would show negative stability in rare
circumstances is now hopefully fixed
- AFL_POST_LIBRARY was deprecated, use AFL_CUSTOM_MUTATOR_LIBRARY
instead (see docs/custom_mutators.md)
- llvm_mode:
- afl-clang-fast/lto now do not skip single block functions. This
behaviour can be reactivated with AFL_LLVM_SKIPSINGLEBLOCK
- if LLVM 11 is installed the posix shm_open+mmap is used and a fixed
address for the shared memory map is used as this increases the
fuzzing speed
- InsTrim now has an LTO version! :-) That is the best and fastest mode!
- fixes to LTO mode if instrumented edges > MAP_SIZE
- CTX and NGRAM can now be used together
- CTX and NGRAM are now also supported in CFG/INSTRIM mode
- AFL_LLVM_LAF_TRANSFORM_COMPARES could crash, fixed
- added AFL_LLVM_SKIP_NEVERZERO to skip the never zero coverage counter
implementation. For targets with few or no loops or heavily called
functions. Gives a small performance boost.
- qemu_mode:
- add information on PIE/PIC load addresses for 32 bit
- better dependency checks
- gcc_plugin:
- better dependency checks
- unicorn_mode:
- validate_crash_callback can now count non-crashing inputs as crash as well

- llvm_mode LTO mode:
- now requires llvm11 - but compiles all targets! :)
- autodictionary feature added, enable with `AFL_LLVM_LTO_AUTODICTIONARY`
- variable map size usage
- afl-fuzz:
- variable map size support added (only LTO mode can use this)
- snapshot feature usage now visible in UI
- Now setting `-L -1` will enable MOpt in parallel to normal mutation.
Additionally, this allows to run dictionaries, radamsa and cmplog.
- fix for cmplog/redqueen mode if stdin was used
- fix for writing a better plot_data file
- qemu_mode: fix for persistent mode (which would not terminate or get stuck)
- compare-transform/AFL_LLVM_LAF_TRANSFORM_COMPARES now transforms also
static global and local variable comparisons (cannot find all though)
- extended forkserver: map_size and more information is communicated to
afl-fuzz (and afl-fuzz acts accordingly)
- new environment variable: AFL_MAP_SIZE to specify the size of the shared map
- if AFL_CC/AFL_CXX is set but empty afl compilers did fail, fixed
(this bug is in vanilla afl too)
- added NO_PYTHON flag to disable python support when building afl-fuzz
