From 3d1cc8ec57f0bf07d7834b652ec2db24e7914624 Mon Sep 17 00:00:00 2001 From: van Hauser Date: Tue, 1 Jun 2021 12:16:56 +0200 Subject: v3.13c release (#951) * persistent replay env setup * implementation without testing * complete implemenation, still no test * fix * fixes * fixes * documentation for AFL_PERSISTENT_RECORD * afl-cmin: Allow @@ to be part of an arg The previous implementation of "@@ handling" in afl-cmin differed greatly from how it was handled in afl-fuzz and how the documentation presented it. It used to require that the @@ be its own argument separated by whitespace and could not be used in situations like "--file=@@". This change standardizes it to just look for @@ to be *in* an argument in the same manner that afl-cmin.bash does, so that it will have the expected and documented behavior. * triage_crashes.sh: Allow @@ to be part of an arg * triage_crashes.sh: Fix error reporting * afl-showmap: Allow @@ to be part of an arg The previous implementation of "@@ handling" in afl-showmap differed greatly from how it was handled in afl-fuzz and how the documentation presented it. It used to require that the @@ be its own argument separated by whitespace and could not be used in situations like "--file=@@". This change standardizes it to use detect_file_args() like everybody else does, so that it will have the expected and documented behavior. * afl-showmap: Unwind a change to keep it pre-C99 compatible * v3.13a init * ifdef for record * changelog info * AFL_PERSISTENT_RECORD not a default * Add support for FRIDA mode * support libraries for find_afl_binary * remove warnings * update dynamic list * update changelog * try to trigger github actions * try to trigger github actions * android: support host and target 32bit build * remove InsTrim * Fix support for afl-cmin and updated README * integrate frida_mode, code-format * update README * Update custom_mutators.md * fix compilation for llvm 3.8.0 * pass lib -ldl only on Linux platforms * typos * simpler argument processing * -m32 support for docker container * restructure havoc * add introspection * ensure one fuzzer sync per cycle, cycle introspection * remove unneeded var * add parallel builds * add parallel builds * Add network_proxy build targets to gitignore (#852) All other build targets in utils/ are ignored except for these due to the lack of file extension. * Fixes: 6d2ac3e3140 ("fix grammar download script") The git submodle entry point is "grammar_mutator" not "grammar-mutator" The build script fails without this * fix #if A == B always evalutes to true * try to avoid CI build failure by updating apt packages * fix k-ctx * Initialalize the autodict-ql Initialalize the autodict-ql add codeql scripts * update the codes, readme - add readme - add required qlpack.yml * update readme update readme * Update readme Update readme * Update readme Update readme * rename python file rename python file * update update * Add shell command Add shell command * update readme update readme * Add support for standalone leak-sanitizer, introducting the environment 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. * Replace __AFL_CHECK_LEAK with __AFL_LEAK_CHECK to be more proper. Fix spelling mistakes. Correctly call LSAN_ERROR not MSAN_ERROR. * Some updates on readme Some updates on readme * Update readme Update readme * Updates update * finalize 1 commit final things * space space * remove things remove things * Add python scripts Add python scripts * Update python scripts Update python scripts * new commit - change strings new commit - change strings * update qlpack name update qlpack name * remove unessential things remove unessential things from scripts * remove dirs remove dirs * Update readme Update readme * Add note Add note * Add ` Add ` * change cur change current dir * Fix typos, Use symbolize=0 for LSAN, Remove syntactic sugar. * Remove check for exit_code on LSAN and replace it with check for symbolize=0. * Move definition of __AFL_LEAK_CHECK inside ifguards, use LSAN_OPTIONS=print_suppressions=0 * revert Heiko's commit * Fix Haiku references, no and missing defines for USEMMAP * cleanup * Add -lnetwork to dependencies for Haiku * fix conflict * Fix undeclared SYS_write on Haiku * Declare private api __kern_write for Haiku * better MacOs msg * Haiku: create directory for debug_server, if not present * add missing env * better understandable directory creation logic * android: disable sigaction inside debuggerd check https://github.com/google/AFL/blob/master/docs/INSTALL#L173 * fix forkserver timeout error msg * removed -lc++ linking for lto * fix afl_custom_queue_new_entry when syncing * update grammar-mutator, show better fuzzing strategy yields * Update ideas.md Hey, I noticed there was a spelling error in above documentation for GSOC '21.

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.
