Instead of modifying in_buf directly, we write the update out to the disk when trimming is complete, and then the caller is responsible for refreshing the in-memory buffer from the file. This is still a bit sketchy because it does need to modify q->len in order to notify the upper layers that something changed, and it could end up telling upper layer code that the q->len is *bigger* than the buffer (q->testcase_buf) that contains it, which is asking for trouble down the line somewhere... * Fix an unlikely situation Put back some `unlikely()` calls that were in the e9d2f72382cab75832721d859c3e731da071435d commit that was reverted. * add some comments * typo * Exit on time (#904) * Variable AFL_EXIT_ON_TIME description has been added. Variables AFL_EXIT_ON_TIME and afl_exit_on_time has been added. afl->exit_on_time variable initialization has been added. The asignment of a value to the afl->afl_env.afl_exit_on_time variable from environment variables has been added. Code to exit on timeout if new path not found has been added. * Type of afl_exit_on_time variable has been changed. Variable exit_on_time has been added to the afl_state_t structure. * Command `export AFL_EXIT_WHEN_DONE=1` has been added. * Millisecond to second conversion has been added. Call get_cur_time() has been added. * Revert to using the saved current time value. * Useless check has been removed. * fix new path to custom-mutators * ensure crashes/README.txt exists * fix * Changes to bump FRIDA version and to clone FRIDA repo in to build directory rather than use a submodule as the FRIDA build scripts don't like it (#906) Co-authored-by: Your Name <you@example.com> * Fix numeric overflow in cmplog implementation (#907) Co-authored-by: Your Name <you@example.com> * testcase fixes for unicorn * remove merge conflict artifacts * fix afl-plot * Changes to remove binaries from frida_mode (#913) Co-authored-by: Your Name <you@example.com> * Frida cmplog fail fast (#914) * Changes to remove binaries from frida_mode * Changes to make cmplog fail fast Co-authored-by: Your Name <you@example.com> * afl-plot: relative time * arch linux and mac os support for afl-system-config * typo * code-format * update documentation * github workflow for qemu * OSX-specific improvements (#912) * Fix afl-cc to work correctly by default on OSX using xcode - CLANG_ENV_VAR must be set for afl-as to work - Use clang mode by default if no specific compiler selected * Add OSX-specific documentation for configuring shared memory * Fixes to memory operands for complog (#916) Co-authored-by: Your Name <you@example.com> * fix a few cur_time uses * added bounds check to pivot_inputs (fixes #921) * additional safety checks for restarts * restrict afl-showmap in_file size * fix seed crash disable * add warning for afl-showmap partial read * no core dumps * AFL_PRINT_FILENAMES added * more documentation for AFL_EXIT_ON_TIME * Flushing for AFL_PRINT_FILENAMES * FASAN Support (#918) * FASAN Support * Fix handling of Address Sanitizer DSO * Changes to identification of Address Sanitizer DSO Co-authored-by: Your Name <you@example.com> * Support for x86 (#920) Co-authored-by: Your Name <you@example.com> * Update frida_mode readme (#925) * libqasan: use syscalls for read and write * update readme * Minor integration tweaks (#926) Co-authored-by: Your Name <you@example.com> * merge * fix afl-fuzz.c frida preload * cleaned up AFL_PRINT_FILENAMES env * Changes to have persistent mode exit at the end of the loop (#928) Co-authored-by: Your Name <you@example.com> * fix llvm-dict2file * push to stable (#931) (#932) * sync (#886) * Create FUNDING.yml * Update FUNDING.yml * moved custom_mutator examples * unicorn speedtest makefile cleanup * fixed example location * fix qdbi * update util readme * Frida persistent (#880) * Added x64 support for persistent mode (function call only), in-memory teest cases and complog * Review changes, fix NeverZero and code to parse the .text section of the main executable.

Efficiency: avoid looping over the whole llvm module N times, when once is also enough. Bitwidth: Previously, due to fallthrough in switch-case, all comparisons were split to 8-bit, which might not be desirable e.g., 16 or 32 bit might be enough. So now all comparison are split until they are smaller or equal to the target bitwidth, which is controlled through the `AFL_LLVM_LAF_SPLIT_COMPARES_BITW` environment variable. * fixed miscompilation due to incorrectly trying to split a signed comparison operator * minor formatting updates and use IRBuilder when inserting multiple instructions * added @hexcoder-'s test-int_cases.c to make test * Avoid recursion; switch to smallvector in splitAndSimplify; use switch case for icmp type; * Fixed issue when splitting < where the inverse comparison was not further split * some cleanup * code format * fix to instrument global c++ namespace functions * update changelog * document frida changes * Fix typo in README.md (#974) * adapt for LLVM 3.8.0 * fix README * little inline * Add debug output to alert user to calibration progress/issues (#969) * aflppdriver help output * code format * afl-cmin/afl-cmin.bash/afl-showmap -i descend into subdirectories * make afl-cmin actually work with subdirectories * correct map size for small targets * Perf regression4 (#979) * Added test for libjpeg * Added proj4 test * Added missing members to x86/64 context * Changes to use memfd and hashtable cache * Removed redundant check Co-authored-by: Your Name <you@example.com> * improve documentation * typo * reverse read the queue n resumes * frida fix * cmplog fix for qemu and frida * Misc (#986) * Changes to fix accidental ranges deletion and add support for SCAS/CMPS * Fix syscall issues on OSX * Changes to more closely match QEMU mode * Changes to use double hashing on cmplog * Changes to use msync * Review changes Co-authored-by: Your Name <you@example.com> * force disable llvm instrumentation for frida * non-unix compat * fix afl-showmap * frida fix * fix frida * rust bindings update * rust bindings update * Added JS support (#992) * Added JS support * Added some documentation Co-authored-by: Your Name <you@example.com> * unicorn rust bindings improvements * typo * updated uc rust bindings * test laf splitting: set default for char type explicitly to signed * Improved FRIDA mode scripting support (#994) Co-authored-by: Your Name <you@example.com> * Select (#995) * favor unfuzzed * fix * reinit table after a new fuzz Co-authored-by: hexcoder- <heiko@hexco.de> Co-authored-by: Dominik Maier <domenukk@gmail.com> Co-authored-by: WorksButNotTested <62701594+WorksButNotTested@users.noreply.github.com> Co-authored-by: Your Name <you@example.com> Co-authored-by: Dmitry Zheregelya <zheregelya.d@gmail.com> Co-authored-by: hexcoder <hexcoder-@users.noreply.github.com> Co-authored-by: Andrea Fioraldi <andreafioraldi@gmail.com> Co-authored-by: David CARLIER <devnexen@gmail.com> Co-authored-by: realmadsci <71108352+realmadsci@users.noreply.github.com> Co-authored-by: Roman M.

Instead of modifying in_buf directly, we write the update out to the disk when trimming is complete, and then the caller is responsible for refreshing the in-memory buffer from the file. This is still a bit sketchy because it does need to modify q->len in order to notify the upper layers that something changed, and it could end up telling upper layer code that the q->len is *bigger* than the buffer (q->testcase_buf) that contains it, which is asking for trouble down the line somewhere... * Fix an unlikely situation Put back some `unlikely()` calls that were in the e9d2f72382cab75832721d859c3e731da071435d commit that was reverted. * typo * Exit on time (#904) * Variable AFL_EXIT_ON_TIME description has been added.

Variable exit_on_time has been added to the afl_state_t structure. * Command `export AFL_EXIT_WHEN_DONE=1` has been added. * Millisecond to second conversion has been added.

2021-01-07User defined kill signal value (#678)buherator
* Adding AFL_KILL_SIGNAL environment variable Controlling the kill signal used to end forked processes. * Checking validity of AFL_KILL_SIGNAL env variable This commit also sets a valid value in the environment to avoid duplicating code in at_exit(). Changing data type of fsrv->kill_signal to u8 to match last_kill_signal. * Adding afl_kill_signal to AFL (environment) state This commit simply introduces a struct member for future use. The env variable is not used from the afl struct but from fsrv, where its validity is checked, resulting in a FATAL in case of errors.

2020-08-23Option for specifying forkserver initialization timeout via environment ↵Marius Muench
variable (#522) * Addition of AFL_FORKSRV_INIT_TMOUT env var This commit introduces a new environment variable which allows to specify the timespan AFL should wait for initial contact with the forkserver. This is useful for fuzz-targets requiring a rather long setup time before the actual fuzzing can be started (e.g., unicorn). * add .swp files to .gitignore * Inherit init_tmout in afl_fsrv_init_dup Without this patch, the forkserver would spawn with a timeout of 0 in cmplog mode, leading to an immediate crash. Additionally, this commit removes a spurious whitespace. * Initialize afl->fsrv.init_tmout in afl_fsrv_init Not all afl-components will need the new AFL_FORKSRV_INIT_TMOUT environment variable. Hence, it's initialized to the safe "default" value from before in afl_fsrv_init now.
