* Pure Python (3.6) port of benchmark.sh as benchmark.py, no other changes * Test standard and persistent modes separately * Add support for multi-core benchmarking * Save the results to a json file * Allow config of all experiment params, average across runs * Add start_time_of_run and total_execs_per_sec, cleanup for PR * benchmark: cleanup, add results, add a data exploration notebook * benchmark: add a README, lower default runs from 5 to 3 * benchmark: notebook wording tweaks * copy 'detect_leaks=0' from ASAN to LSAN fix for issue #1733, set "detect_leaks=0" when ASAN_OPTIONS contains it and LSAN_OPTIONS are not set. * fix of fix: make sure ASAN_OPTIONS and LSAN_OPTIONS agree on leak detection * fix lsan fix * clang-format 16->17 * Add missing initialisation for havoc_queued during the custom mutator's stage. * fix dictionary and cmin * Use direct call to write to OpenBSD The linker on OpenBSD emits a warning when linking this file: warning: syscall() may go away, please rewrite code to use direct calls * Fix possible doc inconsistency for custom mutator's queue_get function. * update todos * benchmark: Add support for COMPARISON file * benchmark: show the number of cores used in COMPARISON * benchmark: lower minimum Python version to 3.8 * benchmark: use afl's execs/s; increase CPU model width * benchmark: disallow duplicate entries for the same CPU in COMPARISON * Update benchmark.py * fix inf in stats * Fix benchmark.py * missing closing parenthesis * Update benchmark.py * benchmark: remove self-calculation of execs/sec * benchmark: update COMPARISON * benchmark: Update Jupyter notebook and results file. * benchmark: rename afl_execs_per_sec to execs_per_sec * benchmark: update README * update * add benchmark * nits * add benchmarks * Update unicornafl ref * Pass correct Nyx ID when creating a Nyx runner * Fix typo in docker pull command, add exampe to mount current dir as volume (#1914) * mini fix * add custom_post_run.c * update afl-fuzz-run * update python module * format code * update * merge function * changes * code format * improve cmplog * nit * nit * fix * fix * Stop hardcoding the path /usr/local/lib/afl in afl-ld-lto.c and respect the configured PREFIX. * Add benchmark for Raspberry Pi 5 * ryzen 5950 benchmark * add missing raspery5 * comparison -> comparison.md * removing options "-Wl,-rpath" "LLVM_LIBDIR" when using gcc * fixing -Wl,-rpath=<LLVM_LIBDIR> * nits * fix * afl-cc fixes * nit * add n_fuzz to ignore_timeouts * fix * Fix #1927 * in-depth blog post * add AFL_FUZZER_LOOPCOUNT * AFL_FUZZER_LOOPCOUNT * fix 2 mutation bugs * v4.09c release * v4.10a init * switch to explore powerschedule as default * fix MUT_INSERTASCIINUM * fix MUT_STRATEGY_ARRAY_SIZE * fix bad fix for MUT_STRATEGY_ARRAY_SIZE * remove afl-network-client on uninstall * update nyx * Improve binary-only related docs * llvm 18 build fixes. * code format * Fix custom_send link Add a leading '/' to walk in the repo root instead of current dir. * Use ../ instead * initial simple injection detection support * inject docs * fix for issue #1916, iLLVM crash in split-floatingpoint-compares * LLVM 17 bug workaround * finish injection implementation * remove tmp todo * update changelog * forgot to add the injection pass * Output afl-clang-fast stuffs only if necessary (#1912) * afl-cc header * afl-cc common declarations - Add afl-cc-state.c - Strip includes, find_object, debug/be_quiet/have_*/callname setting from afl-cc.c - Use debugf_args in main - Modify execvp stuffs to fit new aflcc struct * afl-cc show usage * afl-cc mode selecting 1. compiler_mode by callname in argv[0] 2. compiler_mode by env "AFL_CC_COMPILER" 3. compiler_mode/instrument_mode by command line options "--afl-..." 4. instrument_mode/compiler_mode by various env vars including "AFL_LLVM_INSTRUMENT" 5. final checking steps 6. print "... - mode: %s-%s\n" 7. determine real argv[0] according to compiler_mode * afl-cc macro defs * afl-cc linking behaviors * afl-cc fsanitize behaviors * afl-cc misc * afl-cc body update * afl-cc all-in-one formated with custom-format.py * nits --------- Co-authored-by: vanhauser-thc <vh@thc.org> * changelog * update grammar mutator * lto llvm 12+ * docs(custom_mutators): fix missing ':' (#1953) * Fix broken LTO mode and response file support (#1948) * Strip `-Wl,-no-undefined` during compilation (#1952) Make the compiler wrapper stripping `-Wl,-no-undefined` in addition to `-Wl,--no-undefined`. Both versions of the flag are accepted by clang and, therefore, used by building systems in the wild (e.g., samba will not build without this fix). * Remove dead code in write_to_testcase (#1955) The custom_mutators_count check in if case is duplicate with if condition. The else case is custom_mutators_count == 0, neither custom_mutator_list iteration nor sent check needed.
