------------------------------------------------------------------- Mon Jun 10 08:12:20 UTC 2024 - Marcus Meissner <meissner@suse.com> - updated to 4.21c * afl-fuzz - fixed a regression in afl-fuzz that resulted in a 5-10% performace loss do a switch from gettimeofday() to clock_gettime() which should be rather three times faster. The reason for this is unknown. - new queue selection algorithm based on 2 core years of queue data analysis. gives a noticable improvement on coverage although the results seem counterintuitive :-) - added AFL_DISABLE_REDUNDANT for huge queues - added `AFL_NO_SYNC` environment variable that does what you think it does - fix AFL_PERSISTENT_RECORD - run custom_post_process after standard trimming - prevent filenames in the queue that have spaces - minor fix for FAST schedules - more frequent stats update when syncing (todo: check performance impact) - now timing of calibration, trimming and syncing is measured seperately, thanks to @eqv! - -V timing is now accurately the fuzz time (without syncing), before long calibration times and syncing could result in now fuzzing being made when the time was already run out until then, thanks to @eqv! - fix -n uninstrumented mode when ending fuzzing - enhanced the ASAN configuration - make afl-fuzz use less memory with cmplog and fix a memleak * afl-cc: - re-enable i386 support that was accidently disabled - fixes for LTO and outdated afl-gcc mode for i386 - fix COMPCOV split compare for old LLVMs - disable xml/curl/g_ string transform functions because we do not check for null pointers ... TODO - ensure shared memory variables are visible in weird build setups - compatability to new LLVM 19 changes * afl-cmin - work with input files that have a space * afl-showmap - fix memory leak on shmem testcase usage (thanks to @ndrewh) - minor fix to collect coverage -C (thanks to @bet4it) * Fixed a shmem mmap bug (that rarely came up on MacOS) * libtokencap: script generate_libtoken_dict.sh added by @a-shvedov ------------------------------------------------------------------- Mon Apr 15 09:44:22 UTC 2024 - Marcus Meissner <meissner@suse.com> - updated to 4.20c + A new forkserver communication model is now introduced. afl-fuzz is backward compatible to old compiled targets if they are not built for CMPLOG/Redqueen, but new compiled targets will not work with old afl-fuzz versions! + Recompile all targets that are instrumented for CMPLOG/Redqueen! - AFL++ now supports up to 4 billion coverage edges, up from 6 million. - New compile option: `make PERFORMANCE=1` - this will enable special CPU dependent optimizations that make everything more performant - but the binaries will likely won't work on different platforms. Also enables a faster hasher if the CPU requirements are met. - The persistent record feature (see config.h) was expanded to also support replay, thanks to @quarta-qti ! - afl-fuzz: - the new deterministic fuzzing feature is now activated by default, deactivate with -z. Parameters -d and -D are ignored. - small improvements to CMPLOG/redqueen - workround for a bug with MOpt -L when used with -M - in the future we will either remove or rewrite MOpt. - fix for `-t xxx+` feature - -e extension option now saves the queue items, crashes, etc. with the extension too - fixes for trimmming, correct -V time and reading stats on resume by eqv thanks a lot! - afl-cc: - added collision free caller instrumentation to LTO mode. activate with `AFL_LLVM_LTO_CALLER=1`. You can set a max depth to go through single block functions with `AFL_LLVM_LTO_CALLER_DEPTH` (default 0) - fixes for COMPCOV/LAF and most other modules - fix for GCC_PLUGIN cmplog that broke on std::strings - afl-whatsup: - now also displays current average speed - small bugfixes - Fixes for aflpp custom mutator and standalone tool - Minor edits to afl-persistent-config - Prevent temporary files being left behind on aborted afl-whatsup - More CPU benchmarks added to benchmark/ ------------------------------------------------------------------- Mon Feb 5 10:30:56 UTC 2024 - Marcus Meissner <meissner@suse.com> - updated to 4.10c - afl-fuzz: - default power schedule is now EXPLORE, due a fix in fast schedules explore is slightly better now. - fixed minor issues in the mutation engine, thanks to @futhewo for reporting! - better deterministic fuzzing is now available, benchmarks have shown to improve fuzzing. Enable with -D. Thanks to @kdsjZh for the PR! - afl-cc: - large rewrite by @SonicStark which fixes a few corner cases, thanks! - LTO mode now requires llvm 12+ - workaround for ASAN with gcc_plugin mode - instrumentation: - LLVM 18 support, thanks to @devnexen! - Injection (SQL, LDAP, XSS) fuzzing feature now available, see `instrumentation/README.injections.md` how to activate/use/expand. - compcov/LAF-intel: - floating point splitting bug fix by @hexcoder - due a bug in LLVM 17 integer splitting is disabled there! - when splitting floats was selected, integers were always split as well, fixed to require AFL_LLVM_LAF_SPLIT_COMPARES or _ALL as it should - dynamic instrumentation filtering for LLVM NATIVE, thanks @Mozilla! see utils/dynamic_covfilter/README.md - qemu_mode: - plugins are now activated by default and a new module is included that produces drcov compatible traces for lighthouse/lightkeeper/... thanks to @JRomainG to submitting! - updated Nyx checkout (fixes a bug) and some QOL - updated the custom grammar mutator - document afl-cmin does not work on macOS (but afl-cmin.bash does) ------------------------------------------------------------------- Sun Dec 17 12:08:00 UTC 2023 - Marcus Meissner <meissner@suse.com> - updated to 4.09c - afl-fuzz: - fixed the new mutation implementation for two bugs - added `AFL_FINAL_SYNC` which forces a final fuzzer sync (also for `-F`) before terminating. - added AFL_IGNORE_SEED_PROBLEMS to skip over seeds that time out instead of exiting with an error message - allow -S/-M naming up to 50 characters (from 24) - CMPLOG: - added scale support (-l S) - skip unhelpful insertions (u8) - added --version and --help command line parameters - fixed endless loop when reading malformed dictionaries - new custom mutator function: post_run - thanks to yangzao! - afl-whatsup: - detect instanced that are starting up and show them as such as not dead - now also shows coverage reached - option -m shows only very relevant stats - option -n will not use color in the output - instrumentation: - fix for a few string compare transform functions for LAF - we are instrumenting __cxx internal functions again. this might break a few targets, please report if so. - frida_mode: - fixes support for large map offsets - support for AFL_FUZZER_LOOPCOUNT for afl.rs and LLVMFuzzerTestOneInput - afl-cmin/afl-cmin.bash: prevent unneeded file errors - added new tool afl-addseeds that adds new seeds to a running campaign - added benchmark/benchmark.py if you want to see how good your fuzzing speed is in comparison to other setups. ------------------------------------------------------------------- Fri Aug 11 08:06:00 UTC 2023 - Marcus Meissner <meissner@suse.com> - updated to 4.08c - afl-fuzz: - new mutation engine: mutations that favor discovery more paths are prefered until no new finds for 10 minutes then switching to mutations that favor triggering crashes. Modes and switch time can be configured with `-P`. Also input mode for the target can be defined with `-a` to be `text` or `binary` (defaults to `generic`) - new custom mutator that has the new afl++ engine (so it can easily incorporated into new custom mutators), and also comes with a standalone command line tool! See custom_mutators/aflpp/standalone/ - display the state of the fuzzing run in the UI :-) - fix timeout setting if '+' is used or a session is restarted - -l X option to enable base64 transformation solving - allow to disable CMPLOG with '-c -' (e.g. afl.rs enforces '-c 0' on every instance which is counterproductive). - afl-cmin/afl-cmin.bash: - fixed a bug inherited from vanilla AFL where a coverage of map[123] = 11 would be the same as map[1123] = 1 - warn on crashing inputs - adjust threads if less inputs than threads specified - afl-cc: - fixed an off-by-one instrumentation of iselect, hurting coverage a bit.

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 - printing suggestions for mistyped `AFL_` env variables - added Rust bindings for custom mutators (thanks @julihoh) - afl-cc - allow instrumenting LLVMFuzzerTestOneInput - fixed endless loop for allow/blocklist lines starting with a comment (thanks to Zherya for reporting) - cmplog/redqueen now also tracks floating point, _ExtInt() + 128bit - 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!

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/.

Suggested by Pedro Corte-Real. * Upstreamed several minor changes developed by Franjo Ivancic to allow AFL to be built as a library. This is fairly use-specific and may have relatively little appeal to general audiences. ------------------------------------------------------------------- Sun Feb 28 13:59:04 UTC 2016 - astieger@suse.com - afl 2.05b: * Put __sanitizer_cov_module_init & co behind #ifdef to avoid problems with ASAN. ------------------------------------------------------------------- Wed Feb 24 21:52:33 UTC 2016 - astieger@suse.com - afl 2.04b: * remove indirect-calls coverage from -fsanitize-coverage * LLVM: Added experimental -fsanitize-coverage=trace-pc support - LLVM: better support non-standard map sizes - LLVM: use thread-local execution tracing - Force-disabled symbolization for ASAN - Added AFL_LD_PRELOAD to allow LD_PRELOAD to be set for targets without affecting AFL itself - Fixed a "lcamtuf can't count to 16" bug in the havoc stage. ------------------------------------------------------------------- Tue Feb 16 15:37:01 UTC 2016 - astieger@suse.com - afl 2.01b: - updates to color handling - Fixed an installation issue with afl-as ------------------------------------------------------------------- Thu Feb 11 12:21:39 UTC 2016 - astieger@suse.com - afl 1.99b: - Revamp the output and the internal logic of afl-analyze. - Clean up color handling code - added support for background colors. ------------------------------------------------------------------- Wed Feb 10 20:25:47 UTC 2016 - astieger@suse.com - afl 1.98b: - new tool afl-analyze ------------------------------------------------------------------- Sat Dec 19 15:45:22 UTC 2015 - mpluskal@suse.com - Update to 1.96b * Added -fpic to CFLAGS for the clang plugin, as suggested by Hanno Boeck. * Made another clang change (IRBuilder) suggested by Jeff Trull. * Fixed several typos, spotted by Jakub Wilk. * Added support for AFL_SHUFFLE_QUEUE, based on discussions with Christian Holler. ------------------------------------------------------------------- Fri Nov 13 09:06:47 UTC 2015 - astieger@suse.com - afl 1.95b: * Fixed a harmless bug when handling -B * Made the exit message a bit more accurate when AFL_EXIT_WHEN_DONE is set. * Added some error-checking for old-style forkserver syntax. * Switched from exit() to _exit() in injected code to avoid snafus with destructors in C++ code. * Made a change to avoid spuriously setting __AFL_SHM_ID when AFL_DUMB_FORKSRV is set in conjunction with -n. ------------------------------------------------------------------- Fri Oct 2 15:11:23 UTC 2015 - astieger@suse.com - afl 1.94b: * Changed allocator alignment to improve support for non-x86 systems (now that llvm_mode makes this more feasible). * Fixed an obscure bug that would affect people trying to use afl-gcc with $TMP set but $TMPDIR absent. ------------------------------------------------------------------- Mon Sep 7 13:22:07 UTC 2015 - astieger@suse.com - afl 1.92b: * C++ fix (namespaces) ------------------------------------------------------------------- Thu Sep 3 14:32:09 UTC 2015 - astieger@suse.com - afl 1.91b: * C++ instrumentation fixes - includes changes from 1.90b: * documentation updates * Fixed a potential problem with deferred mode signatures getting optimized out by the linker (with --gc-sections). ------------------------------------------------------------------- Wed Sep 2 07:57:31 UTC 2015 - astieger@suse.com - afl 1.89b: * Revamped the support for persistent and deferred forkserver modes.
