2021-03-02cpu-exec: Add AFL_QEMU_EXCLUDE_RANGESrealmadsci
This environment variable allows rejection of specific regions from instrumentation. It takes priority over AFL_INST_LIBS and AFL_QEMU_INST_RANGES, so it can be used to poke a "hole" in previously included sections.

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.

2020-09-08rewrite gcc pluginAlexandre Oliva
When we started using AFL, it did not have an integrated GCC plugin. There was one proposed by Austin Seipp, but for various reasons we ended up using some of its infrastructure (runtime and wrapper), but writing the GCC plugin proper from scratch. With AFL++'s renewed interest in a GCC plugin, we rebased ours, with some features that are or were missing in the one that was integrated: * efficient, fully-functional inline and out-of-line instrumentation Inline instrumentation was work in progress in the original plugin. Controlled by AFL_GCC_OUT_OF_LINE. * reproducible instrumentation Obey -frandom-seed for pseudorandom number generation. * licensing clarity and strict compliance GPLv3+ for the plugin, that uses GCC internals; add a copy of the license, as required. * allow/deny list support Copied and adjusted from the LLVM plugin implementation. * neverZero support Not as compact as the asm-wrapper version, but likely more efficient. Both are quite thread-unsafe, with different caveats. Controlled with AFL_GCC_SKIP_NEVERZERO.

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.
