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.

AFL++ Examples
Here's a quick overview of the stuff you can find in this directory:
-
aflpp_driver - easily instrument LLVMFuzzerTestOneInput() harnesses.
-
afl_network_proxy - fuzz a target over the network: afl-fuzz on a host, target on an embedded system.
-
plot_ui - simple UI window utility to display the plots generated by afl-plot
-
afl_proxy - skeleton file example to show how to fuzz something where you gather coverage data via different means, e.g., hw debugger
-
afl_untracer - fuzz binary-only libraries much faster but with less coverage than QEMU mode
-
analysis_scripts - random -o out analysis scripts
-
argv_fuzzing - a simple wrapper to allow cmdline to be fuzzed (e.g., to test setuid programs).
-
asan_cgroups - a contributed script to simplify fuzzing ASAN binaries with robust memory limits on Linux.
-
autodict_ql - generate dictionary files from source code.
-
bash_shellshock - a simple hack used to find a bunch of post-Shellshock bugs in bash.
-
canvas_harness - a test harness used to find browser bugs with a corpus generated using simple image parsing binaries & afl-fuzz.
-
clang_asm_normalize - a script that makes it easy to instrument hand-written assembly, provided that you have clang.
-
crash_triage - a very rudimentary example of how to annotate crashes with additional gdb metadata.
-
custom_mutators - examples for the AFL++ custom mutator interface in C and Python. Note: They were moved to ../custom_mutators/examples/
-
defork - intercept fork() in targets
-
distributed_fuzzing - a sample script for synchronizing fuzzer instances across multiple machines.
-
libdislocator - like ASAN but lightweight.
-
libtokencap - collect string tokens for a dictionary.
-
libpng_no_checksum - a sample patch for removing CRC checks in libpng.
-
persistent_mode - an example of how to use the LLVM persistent process mode to speed up certain fuzzing jobs.
-
qemu_persistent_hook - persistent mode support module for qemu.
-
socket_fuzzing - a LD_PRELOAD library 'redirects' a socket to stdin for fuzzing access with AFL++
Note that the minimize_corpus.sh tool has graduated from the utils/ directory and is now available as ../afl-cmin. The LLVM mode has likewise graduated to ../instrumentation/*.
Most of the tools in this directory are meant chiefly as examples that need to be tweaked for your specific needs. They come with some basic documentation, but are not necessarily production-grade.
