Revisions of afl
- updated to 2.58c - reverted patch to not unlink and recreate the input file, it resulted in performance loss of ~10% - added test/test-performance.sh script - (re)added gcc_plugin, fast inline instrumentation is not yet finished, however it includes the whitelisting and persistance feature! by hexcoder- - gcc_plugin tests added to testing framework - jump to 2.57 instead of 2.55 to catch up with Google's versioning - persistent mode for QEMU (see qemu_mode/README.md) - custom mutator library is now an additional mutator, to exclusivly use it - add AFL_CUSTOM_MUTATOR_ONLY (that will trigger the previous behaviour) - new library qemu_mode/unsigaction which filters sigaction events - afl-fuzz: new command line option -I to execute a command on a new crash - no more unlinking the input file, this way the input file can also be a - FIFO or disk partition - setting LLVM_CONFIG for llvm_mode will now again switch to the selected - llvm version. If your setup is correct. - fuzzing strategy yields for custom mutator were missing from the UI, added them :) - added "make tests" which will perform checks to see that all functionality - is working as expected. this is currently the starting point, its not complete :) - added mutation documentation feature ("make document"), creates afl-fuzz-document - and saves all mutations of the first run on the first file into out/queue/mutations - libtokencap and libdislocator now compile to the afl_root directory and are - installed to the .../lib/afl directory when present during make install - more BSD support, e.g. free CPU binding code for FreeBSD (thanks to devnexen) - reducing duplicate code in afl-fuzz - added "make help" - removed compile warnings from python internal stuff - added man page for afl-clang-fast[++] - updated documentation - Wine mode to run Win32 binaries with the QEMU instrumentation (-W) - CompareCoverage for ARM target in QEMU/Unicorn
afl 2.51b
- include docs/README
- Version 2.49b - Added AFL_TMIN_EXACT to allow path constraint for crash minimization. - Added dates for releases (retroactively for all of 2017). - Version 2.48b - Added AFL_ALLOW_TMP to permit some scripts to run in /tmp. - Fixed cwd handling in afl-analyze (similar to the quirk in afl-tmin). - Made it possible to point -o and -f to the same file in afl-tmin. - Version 2.47b - Fixed cwd handling in afl-tmin. Spotted by Jakub Wilk. - Version 2.46b - libdislocator now supports AFL_LD_NO_CALLOC_OVER for folks who do not want to abort on calloc() overflows. - Made a minor fix to libtokencap. Reported by Daniel Stender. - Added a small JSON dictionary, inspired on a dictionary done by Jakub Wilk. (forwarded request 512610 from msmeissn)
- update to 2.45b: - Added strstr, strcasestr support to libtokencap. Contributed by Daniel Hodson. - Fixed a resumption offset glitch spotted by Jakub Wilk. - There are definitely no bugs in afl-showmap -c now.
afl 2.44b
- update to 2.41b: - Addressed a major user complaint related to timeout detection. Timing out 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. - Made a small improvement to the havoc block insertion strategy. - Adjusted color rules for "is it done yet?" indicators.

- update to 2.39b: - Improved error reporting in afl-cmin. Suggested by floyd. - Made a minor tweak to trace-pc-guard support. Suggested by kcc. - Added a mention of afl-monitor. - update to 2.38b: * Added -mllvm -sanitizer-coverage-block-threshold=0 to trace-pc-guard mode * Fixed a cosmetic bad free() bug when aborting -S sessions * Made a small change to afl-whatsup to sort fuzzers by name. * 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.

- 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. 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. - Version 2.28b: - Added "life pro tips" to docs/. - Moved testcases/_extras/ to dictionaries/ for visibility. - Made minor improvements to install scripts. - Added an important safety tip. - Version 2.27b: - Added libtokencap, a simple feature to intercept strcmp / memcmp and generate dictionary entries that can help extend coverage.
