Tue Jun 8 09:06:11 UTC 2021 - Andreas Schwab <schwab@suse.de>
- Fix filelist for riscv64
-------------------------------------------------------------------
Tue Jun 1 10:36:06 UTC 2021 - Marcus Meissner <meissner@suse.com>
- updated to 3.13c
- 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.
- added AFL_TRY_AFFINITY to try to bind to CPUs but don't error if
it fails
- afl-cc:
- We do not support llvm versions prior 6.0 anymore
- added thread safe counters to all modes (`AFL_LLVM_THREADSAFE_INST`),
note that this disables NeverZero counters.

Tue Mar 16 07:43:01 UTC 2021 - Marcus Meissner <meissner@suse.com>
- 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
-------------------------------------------------------------------

- update to 3.10c
- Mac OS ARM64 support
- Android support fixed and updated by Joey Jiaojg - thanks!
- 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
- fix for `-Z`
- fixed a few crashes
- switched to an even faster RNG
- added hghwng's patch for faster trace map analysis

- cmplog/redqueen can now process basic libc++ and libstdc++
std::string comparisons (no position or length type variants)
- added support for __afl_coverage_interesting() for LTO and our
own PCGUARD (llvm 10.0.1+), read more about this function and
selective coverage in instrumentation/README.instrument_list.md
- added AFL_LLVM_INSTRUMENT option NATIVE for native clang pc-guard
support (less performant than our own), GCC for old afl-gcc and
CLANG for old afl-clang
- fixed a potential crash in the LAF feature
- workaround for llvm bitcast lto bug
- workaround for llvm 13
- qemuafl
- QASan (address sanitizer for Qemu) ported to qemuafl!

- Updated utils/afl_frida to be 5% faster, 7% on x86_x64
- Added `AFL_KILL_SIGNAL` env variable (thanks @v-p-b)
- @Edznux added a nice documentation on how to use rpc.statsd with
afl++ in docs/rpc_statsd.md, thanks!
-------------------------------------------------------------------

- 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

- instrumentation
- We received an enhanced gcc_plugin module from AdaCore, thank you
very much!!
- not overriding -Ox or -fno-unroll-loops anymore
- we now have our own trace-pc-guard implementation. It is the same as
-fsanitize-coverage=trace-pc-guard from llvm 12, but: it is a) inline
and b) works from llvm 10.0.1 + onwards :)
- new llvm pass: dict2file via AFL_LLVM_DICT2FILE, create afl-fuzz
-x dictionary of string comparisons found during compilation
- LTO autodict now also collects interesting cmp comparisons,
std::string compare + find + ==, bcmp

- updated to 2.68c
- added the GSoC excellent afl++ grammar mutator by Shengtuo to our
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

Wed Aug 19 14:35:25 UTC 2020 - Marcus Meissner <meissner@suse.com>
- 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
to prevent llvm optimizing away the splits
- LTO: autodictionary mode is a fixed default now

-------------------------------------------------------------------
Thu Jul 2 09:59:38 UTC 2020 - Marcus Meissner <meissner@suse.com>
- 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
needs 3.8.0)
- instrument_file list feature now supports wildcards (thanks to sirmc)
- small change to cmplog to make it work with current llvm 11-dev
- added AFL_LLVM_LAF_ALL, sets all laf-intel settings
- LTO instrument_files functionality rewritten, now main, _init etc functions
need not to be listed anymore
- fixed crash in compare-transform-pass when strcasecmp/strncasecmp was
tried to be instrumented with LTO
- fixed crash in cmplog with LTO
- enable snapshot lkm also for persistent mode
- Unicornafl
- Added powerPC support from unicorn/next
- rust bindings!
- CMPLOG/Redqueen now also works for MMAP sharedmem
- ensure shmem is released on errors
- we moved radamsa to be a custom mutator in ./custom_mutators/. It is not
compiled by default anymore.
- allow running in /tmp (only unsafe with umask 0)
- persistent mode shared memory testcase handover (instead of via
files/stdin) - 10-100% performance increase
- General support for 64 bit PowerPC, RiscV, Sparc etc.
- fix afl-cmin.bash
- slightly better performance compilation options for afl++ and targets
- fixed afl-gcc/afl-as that could break on fast systems reusing pids in
the same second
- added lots of dictionaries from oss-fuzz, go-fuzz and Jakub Wilk
- added former post_library examples to examples/custom_mutators/
- Dockerfile upgraded to Ubuntu 20.04 Focal and installing llvm 11 and
gcc 10 so afl-clang-lto can be build
-------------------------------------------------------------------
Fri May 15 09:24:47 UTC 2020 - Marcus Meissner <meissner@suse.com>
- 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.
- 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
- better submodule handling
- afl-showmap: fix for -Q mode
- added examples/afl_network_proxy which allows to fuzz a target over the
network (not fuzzing tcp/ip services but running afl-fuzz on one system
and the target being on an embedded device)
- added examples/afl_untracer which does a binary-only fuzzing with the
modifications done in memory (intel32/64 and aarch64 support)
- added examples/afl_proxy which can be easily used to fuzz and instrument
non-standard things
- all:
- forkserver communication now also used for error reporting
- fix 32 bit build options
- make clean now leaves qemu-3.1.1.tar.xz and the unicornafl directory
intact if in a git/svn checkout - unless "deepclean" is used
-------------------------------------------------------------------

- updated to 2.64c
- 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:

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
-------------------------------------------------------------------
Sun Apr 12 11:04:35 UTC 2020 - Marcus Meissner <meissner@suse.com>
- updated to 2.63c

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
- Added llvm_mode NGRAM prev_loc coverage by Adrean Herrera
(https://github.com/adrianherrera/afl-ngram-pass/), activate by setting
AFL_LLVM_INSTRUMENT=NGRAM-<value> or AFL_LLVM_NGRAM_SIZE=<value>
- Added llvm_mode context sensitive branch coverage, activated by setting
AFL_LLVM_INSTRUMENT=CTX or AFL_LLVM_CTX=1
- llvm_mode InsTrim mode:

should be
3. (major) incorrect prev_loc was written, fixed!
- afl-clang-fast:
- show in the help output for which llvm version it was compiled for

Thu Aug 25 12:45:55 UTC 2016 - meissner@suse.com
- Version 2.32b:
- 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.
- Fixed a minor glitch with a leftover process in persistent mode.

it out with AFL_LD_PRELOAD=/path/to/libdislocator.so when running
afl-fuzz.
- Version 2.23b:
- Improved the stability metric for persistent mode binaries. Problem
spotted by Kurt Roeckx.
- Made a related improvement that may bring the metric to 100% for those
targets.
- Version 2.22b:
- Mentioned the potential conflicts between MSAN / ASAN and FORTIFY_SOURCE.
There is no automated check for this, since some distros may implicitly
set FORTIFY_SOURCE outside of the compiler's argv[].
- Populated the support for AFL_LD_PRELOAD to all companion tools.
- Made a change to the handling of ./afl-clang-fast -v. Spotted by
Jan Kneschke.

docs. Courtesy Sam Hakim and David A. Wheeler.
* Refactored afl-tmin to reduce the number of execs in common use cases.
Ideas from Jonathan Neuschafer and Turo Lamminen.
* Added a note about CLAs at the bottom of README.
* Renamed testcases_readme.txt to README.testcases for some semblance of
consistency.
* Made assorted updates to docs.
- includes changes from 1.59b
