- Added a check for AFL_HARDEN combined with AFL_USE_*SAN. Suggested by Hanno Boeck.
- Made several other cosmetic adjustments to cycle timing in the wake of the big tweak made in 2.31b.
- Version 2.31b:
- Changed havoc cycle counts for a marked performance boost, especially
with -S / -d. See the discussion of FidgetyAFL in:
https://groups.google.com/forum/#!topic/afl-users/fOPeb62FZUg
While this does not implement the approach proposed by the authors of
the CCS paper, the solution is a result of digging into that research;
more improvements may follow as I do more experiments and get more
definitive data.
- Version 2.30b:
- Made minor improvements to persistent mode to avoid the remote
possibility of "no instrumentation detected" issues with very low
instrumentation densities.

Reported by Jakub Wilk and Daniel Stender.
- Made persistent mode bitmaps a bit more consistent and adjusted the way
this is shown in the UI, especially in persistent mode.
- Version 2.29b:
- Made a minor #include fix to llvm_mode. Suggested by Jonathan Metzman.
- Made cosmetic updates to the docs.

* Fixed a minor issue with malloc(0) in libdislocator
* Changed the clobber pattern in libdislocator to a slightly more
reliable one
* Added a note about THP performance
* Added a somewhat unofficial support for running afl-tmin with a
baseline "mask" that causes it to minimize only for edges that
are unique to the input file, but not to the "boring" baseline.
* "Fixed" a getPassName() problem with never versions of clang.455996ec4b501d4c50da1313978bd08678ba182.39bdimstar_suse147789757752c02c42137ca7e6edf4480793ebc2.41bmaxlin_factory- update to 2.41b:

inputs are now binned as "hangs" only if they exceed a far more generous
time limit than the one used to reject slow paths.
- update to 2.40b:
- Fixed a minor oversight in the insertion strategy for dictionary words.
Spotted by Andrzej Jackowski.

- all:
- big code changes to make afl-fuzz thread-safe so afl-fuzz can spawn
multiple fuzzing threads in the future or even become a library
- afl basic tools now report on the environment variables picked up
- more tools get environment variable usage info in the help output
- force all output to stdout (some OK/SAY/WARN messages were sent to
stdout, some to stderr)
- uninstrumented mode uses an internal forkserver ("fauxserver")
- now builds with `-D_FORTIFY_SOURCE=2`
- drastically reduced number of (de)allocations during fuzzing
- afl-fuzz:
- python mutator modules and custom mutator modules now use the same
interface and hence the API changed
- AFL_AUTORESUME will resume execution without the need to specify `-i -`
- added experimental power schedules (-p):
- mmopt: ignores runtime of queue entries, gives higher weighting to
the last 5 queue entries

runtime
- llvm_mode:
- added SNAPSHOT feature (using https://github.com/AFLplusplus/AFL-Snapshot-LKM)

easier: DEFAULT, CFG (INSTRIM), LTO, CTX, NGRAM-x (x=2-16)
- made USE_TRACE_PC compile obsolete
- LTO collision free instrumented added in llvm_mode with afl-clang-lto -
note that this mode is amazing, but quite some targets won't compile

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
- more refactoring (forwarded request 795493 from msmeissn)79549477fa9af715afae54a2165c47f7927dbb2.65cdimstar_suse- updated to 2.65c
- 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.

- better dependency checks
- gcc_plugin:
- better dependency checks
- unicorn_mode:
- validate_crash_callback can now count non-crashing inputs as crash as well
- better submodule handling (forwarded request 805785 from msmeissn)8057876d99881c19893bc5910837898b7ee0b92.66cdimstar_suse- updated to 2.66c
- renamed blacklist/whitelist to ignorelist/instrumentlist ->
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)8183251cba31032ea50e49bea977cf0420b80b2.67cdimstar_suse- updated to 2.67c

- 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 :)

- 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)8279140d026e50ed9e20f66a5e81c74c77b9112.68cdimstar_suse- updated to 2.68c

custom_mutators/ (see custom_mutators/README.md) - or get it here:
https://github.com/AFLplusplus/Grammar-Mutator
- a few QOL changes for Apple and its outdated gmake
- afl-fuzz:
- fix for auto dictionary entries found during fuzzing to not throw out
a -x dictionary
- added total execs done to plot file
- AFL_MAX_DET_EXTRAS env variable added to control the amount of
deterministic dict entries without recompiling.
- AFL_FORKSRV_INIT_TMOUT env variable added to control the time to wait
for the forkserver to come up without the need to increase the overall
timeout.
- bugfix for cmplog that results in a heap overflow based on target data
(thanks to the magma team for reporting!)
- write fuzzing setup into out/fuzzer_setup (environment variables and
command line)
- custom mutators:
- added afl_custom_fuzz_count/fuzz_count function to allow specifying
the number of fuzz attempts for custom_fuzz
- llvm_mode:
- ported SanCov to LTO, and made it the default for LTO. better
instrumentation locations
- Further llvm 12 support (fast moving target like afl++ :-) )

- 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)8560033d07e873b06b3441070e7b6eb6bb59243.10cRBrownSUSE- update to 3.10c

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
- fix for `-Z`
- fixed a few crashes8759497f5a05221f1576acc954841ca903a41a3.11cRBrownSUSE- updated to 3.11c
- afl-fuzz:
- better auto detection of map size
- fix sanitizer settings (bug since 3.10c)
- fix an off-by-one overwrite in cmplog
- add non-unicode variants from unicode-looking dictionary entries
- Rust custom mutator API improvements
- Imported crash stats painted yellow on resume (only new ones are red)
- afl-cc:
- added AFL_NOOPT that will just pass everything to the normal
gcc/clang compiler without any changes - to pass weird configure
scripts
- fixed a crash that can occur with ASAN + CMPLOG together plus
better support for unicode (thanks to @stbergmann for reporting!)
- fixed a crash in LAF transform for empty strings
- handle erroneous setups in which multiple afl-compiler-rt are
compiled into the target. This now also supports dlopen()
instrumented libs loaded before the forkserver and even after the
forkserver is started (then with collisions though)
- the compiler rt was added also in object building (-c) which
should have been fixed years ago but somewhere got lost :(
- Renamed CTX to CALLER, added correct/real CTX implementation to
CLASSIC
- qemu_mode:
- added AFL_QEMU_EXCLUDE_RANGES env by @realmadsci, thanks!
- if no new/updated checkout is wanted, build with:
NO_CHECKOUT=1 ./build_qemu_support.sh
- we no longer perform a "git drop"
- afl-cmin: support filenames with spaces
- afl-3.0c-fix-paths.patch: refreshed (forwarded request 879398 from msmeissn)87939947a25c4dc123fb7ba4ea3d9b657671a23.12cRBrownSUSE- updated to 3.12c
- afl-fuzz:
- added AFL_TARGET_ENV variable to pass extra env vars to the target
(for things like LD_LIBRARY_PATH)
- fix map detection, AFL_MAP_SIZE not needed anymore for most cases
- fix counting favorites (just a display thing)
- afl-cc:
- fix cmplog rtn (rare crash and not being able to gather ptr data)
- fix our own PCGUARD implementation to compile with llvm 10.0.1
- link runtime not to shared libs
- ensure shared libraries are properly built and instrumented
- AFL_LLVM_INSTRUMENT_ALLOW/DENY were not implemented for LTO, added
- show correct LLVM PCGUARD NATIVE mode when auto switching to it
and keep fsanitize-coverage-*list=...
Short mnemnonic NATIVE is now also accepted.

- move AFL_PRELOAD and AFL_USE_QASAN logic inside afl-qemu-trace
- add AFL_QEMU_CUSTOM_BIN
- unicorn_mode
- accidently removed the subfolder from github, re-added
- added DEFAULT_PERMISSION to config.h for all files created, default
to 0600 (forwarded request 881188 from msmeissn)881268adf61607e46eb48a424e9f50d01c50583.12cRBrownSUSE- Fix packaging on aarch64 and %{arm} (forwarded request 881925 from Guillaume_G)88192677811a2fda1763331dccd4d94c11b47a3.12cRBrownSUSE- install `afl-clang-lto`, recommended by upstream as the best variant

- Note: plot_data switched to relative time from unix time in 3.10
- frida_mode - new mode that uses frida to fuzz binary-only targets,
it currently supports persistent mode and cmplog.
thanks to @WorksButNotTested!
- create a fuzzing dictionary with the help of CodeQL thanks to
@microsvuln! see utils/autodict_ql
- afl-fuzz:
- added patch by @realmadsci to support @@ as part of command line
options, e.g. `afl-fuzz ... -- ./target --infile=@@`
- add recording of previous fuzz attempts for persistent mode
to allow replay of non-reproducable crashes, see
AFL_PERSISTENT_RECORD in config.h and docs/envs.h
- fixed a bug when trimming for stdin targets
- cmplog -l: default cmplog level is now 2, better efficiency.
level 3 now performs redqueen on everything. use with care.
- better fuzzing strategy yield display for enabled options
- ensure one fuzzer sync per cycle
- fix afl_custom_queue_new_entry original file name when syncing
from fuzzers
- fixed a crash when more than one custom mutator was used together
with afl_custom_post_process
- on a crashing seed potentially the wrong input was disabled
- added AFL_EXIT_ON_SEED_ISSUES env that will exit if a seed in
-i dir crashes the target or results in a timeout. By default
afl++ ignores these and uses them for splicing instead.
- added AFL_EXIT_ON_TIME env that will make afl-fuzz exit fuzzing
after no new paths have been found for n seconds
- when AFL_FAST_CAL is set a variable path will now be calibrated
8 times instead of originally 40. Long calibration is now 20.

(like afl-fuzz does) - note that afl-cmin.bash does not!
- afl_analyze:
- fix timeout handling (forwarded request 907257 from msmeissn)907258b567db90a386b5bb7044540191bda8873.14cdimstar_suse- enable gcc-plugin on factory

- 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

- 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!

- 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)95019741f14a22723c16a75da3f426eb0b76264.00cdimstar_suse966170607281e8e5dc2490060f77c2be1056584.00cdimstar_suse- Add llvm14-fix-build.patch: fix build with LLVM 14.

- 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

- 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.
