* 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. Signed-off-by: Xeonacid <h.dwwwwww@gmail.com> * update qemuafl * WIP: Add ability to generate drcov trace using QEMU backend (#1956) * Document new drcov QEMU plugin * Add link to lightkeeper for QEMU drcov file loading --------- Co-authored-by: Jean-Romain Garnier <jean-romain.garnier@airbus.com> * code format * changelog * sleep on uid != 0 afl-system-config * fix segv about skip_next, warn on unsupported cases of linking options (#1958) * todos * ensure afl-cc only allows available compiler modes * update grammar mutator * disable aslr on apple * fix for arm64 * help selective instrumentation * typos * macos * add compiler test script * apple fixes * bump nyx submodules (#1963) * fix docs * update changelog * update grammar mutator * improve compiler test script * gcc asan workaround (#1966) * fix github merge fuckup * fix * Fix afl-cc (#1968) - Check if too many cmdline params here, each time before insert a new param. - Check if it is "-fsanitize=..." before we do sth. - Remove improper param_st transfer. * Avoid adding llvmnative instrumentation when linking rust sanitizer runtime (#1969) * Dynamic instrumentation filtering for LLVM native (#1971) * Add two dynamic instrumentation filter methods to runtime * Always use pc-table with native pcguard * Add make_symbol_list.py and README * changelog * todos * new forkserver check * fix * nyx test for CI * improve nyx docs * Fixes to afl-cc and documentation (#1974) * Always compile with -ldl when building for CODE_COVERAGE When building with CODE_COVERAGE, the afl runtime contains code that calls `dladdr` which requires -ldl. 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>

2021-05-07Fix memory errors when trim causes testcase growth (#881) (#903)realmadsci
* Revert "fixed potential double free in custom trim (#881)" This reverts commit e9d2f72382cab75832721d859c3e731da071435d. * Revert "fix custom trim for increasing data" This reverts commit 86a8ef168dda766d2f25f15c15c4d3ecf21d0667. * Fix memory errors when trim causes testcase growth Modify trim_case_custom to avoid writing into in_buf because some custom mutators can cause the testcase to grow rather than shrink. 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.
