2024-03-14Fix invalid range for del_len_limitgnbon
2024-03-13Add -l option for adjustable block deletiongnbon
- Introduce the -l option to set min block deletion length using powers of 2 (e.g., 1, 2, 4, 8, 16, ...). - This enables a trade-off between minimization thoroughness and speed. - Adjusting del_len_limit allows for faster processing, as doubling it roughly halves the minimization time.

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.

Under most circumstances, clang already adds this (e.g. when building with pc-table), but there are some circumstances where it isn't added automatically. * Add visibility declaration to __afl_connected When building with hidden visibility, the use of __AFL_LOOP inside such code can cause linker errors due to __afl_connected being declared "hidden". * Update docs to clarify that CODE_COVERAGE=1 is required for dynamic_covfilter * nits * nyx build script updates * test error output * debug ci * debug ci * Improve afl-cc (#1975) * update response file support - full support of rsp file - fix some segv issues * Improve afl-cc - remove dead code about allow/denylist options of sancov - missing `if (!aflcc->have_msan)` - add docs for each function - typo * enable nyx * debug ci * debug ci * debug ci * debug ci * debug ci * debug ci * debug ci * debug ci * fix ci * clean test script * NO_NYX * NO_NYX * fix ci * debug ci * fix ci * finalize ci fix * Enhancement on Deterministic stage (#1972) * fuzzer: init commit based on aflpp 60dc37a8cf09f8e9048e4b6a2204d6c90b27655a * fuzzers: adding the skip variables and initialize * log: profile the det/havoc finding * log: add profile log output * fuzzers: sperate log/skipdet module * fuzzers: add quick eff_map calc * fuzzers: add skip_eff_map in fuzz_one * fuzzers: mark whole input space in eff_map * fuzzers: add undet bit threshold to skip some seeds * fuzzers: fix one byte overflow * fuzzers: fix overflow * fix code format * add havoc only again * code format * remove log to INTROSPECTION, rename skipdet module * rename skipdet module * remove log to stats * clean redundant code * code format * remove redundant code format check * remove redundant doc * remove redundant objects * clean files * change -d to default skipdet * disable deterministic when using CUSTOM_MUTATOR * revert fix * final touches for skipdet * remove unused var * remove redundant eff struct (#1977) * update QEMU-Nyx submodule (#1978) * update QEMU-Nyx submodule (#1980) * Fix type in AFL_NOOPT env variable in afl-cc help message (#1982) * nits * 2024 v4.10c release * fixes --------- Signed-off-by: Xeonacid <h.dwwwwww@gmail.com> Co-authored-by: Sonic <50692172+SonicStark@users.noreply.github.com> Co-authored-by: Xeonacid <h.dwwwwww@gmail.com> Co-authored-by: Nils Bars <nils.bars@rub.de> Co-authored-by: Jean-Romain Garnier <7504819+JRomainG@users.noreply.github.com> Co-authored-by: Jean-Romain Garnier <jean-romain.garnier@airbus.com> Co-authored-by: Sergej Schumilo <sergej@schumilo.de> Co-authored-by: Christian Holler (:decoder) <choller@mozilla.com> Co-authored-by: Han Zheng <35988108+kdsjZh@users.noreply.github.com> Co-authored-by: Khaled Yakdan <yakdan@code-intelligence.com>

2022-10-24AFL_FORK_SERVER_KILL_SIGNAL backwards compatiblityNils Bars
If `AFL_KILL_SIGNAL` is set, `AFL_FORK_SERVER_KILL_SIGNAL` is set to the same value.
2022-10-21Add AFL_FORK_SERVER_KILL_SIGNAL environment variable.Nils Bars
The AFL_FORK_SERVER_KILL_SIGNAL variable allows to configure the signal used to kill the fork server on termination.
2022-10-20Fix child reaping on fuzzer terminationNils Bars
This commit contains the following changes: - Call `waitpid()` on the child and the fork server when terminating the fuzzer; thus, we do not end up with zombies. - Rename `fsrv.kill_signal` to `fsrv.child_kill_signal`, since the documentation states that the signal is used to terminate the *child*. - Use SIGTERM instead of fsrv.(child)_kill_signal, thus the fork server can always reap the child.

2021-04-02 Add support for standalone leak-sanitizer, introducting the environmentJoshua Rogers
variable AFL_USE_LSAN. AFL_USE_LSAN introduces the macro __AFL_CHECK_LEAK() which will check for a memory leak when the macro is run. This is especially helpful when using __AFL_LOOP(). If __AFL_LEAK_CHECK() is not used when AFL_USE_LSAN=1 is set, the leak checker will run when the program exits.

2021-03-15Remove AFL_PRELOAD and AFL_USE_QASAN handlersrealmadsci
These are now processed in afl-qemu-trace so that the "copy+paste" code that is in all of the other AFL tools can be removed. This also allows the AFL_USE_QASAN flag to work the same when used with tools like afl-fuzz as it does with afl-qemu-trace. This is important in situations where loading the QASAN library changes the address of your desired entrypoint, or for crash validation using the same environment that afl-fuzz was using. With this change, the same set of environment variables can be used in exactly the same way between afl-fuzz, afl-showmap, and afl-qemu-trace, and you will get exactly the same guest environment.
