AFL++ is a superior fork to Google's AFL - more speed, more and better
mutations, more and better instrumentation, custom module support, etc.

# TODO list for AFL++
## Must
- hardened_usercopy=0 page_alloc.shuffle=0
- add value_profile but only enable after 15 minutes without finds
- cmplog max items env?
- adapt MOpt to new mutation engine
- Update afl->pending_not_fuzzed for MOpt
- cmplog rtn sanity check on fixed length? currently we ignore the length
- afl-showmap -f support
- afl-fuzz multicore wrapper script
- when trimming then perform crash detection
## Should
- afl-crash-analysis
- test cmplog for less than 16bit
- support persistent and deferred fork server in afl-showmap?
- better autodetection of shifting runtime timeout values
- Update afl->pending_not_fuzzed for MOpt
- afl-plot to support multiple plot_data
- parallel builds for source-only targets
- get rid of check_binary, replace with more forkserver communication
@ -36,7 +25,8 @@ QEMU mode/FRIDA mode:
- non colliding instrumentation
- rename qemu specific envs to AFL_QEMU (AFL_ENTRYPOINT, AFL_CODE_START/END,
AFL_COMPCOV_LEVEL?)
- add AFL_QEMU_EXITPOINT (maybe multiple?)
- add AFL_QEMU_EXITPOINT (maybe multiple?), maybe pointless as there is
persistent mode
## Ideas

# American Fuzzy Lop plus plus (AFL++)
## benchmarking
This directory contains benchmarking tools that allow you to compare one machine
with another in terms of raw ability to execute a fuzzing target repeatedly.
To achieve this, we use a sample program ("test-instr.c") where each path is
equally likely, supply it a single seed, and tell AFL to exit after one run of
deterministic mutations against that seed.
**Note that this is not a real-world scenario!**
Because the target does basically nothing this is rather a stress test on
Kernel I/O / context switching.
For this reason you will not see a difference if you run the multicore test
with 20 or 40 threads - or even see the performance decline the more threads
(`-f` parameter) you use. In a real-world scenario you can expect to gain
exec/s until 40-60 threads (if you have that many available on your CPU).
Usage example:
```
cd aflplusplus/benchmark
python3 benchmark.py
[*] Ready, starting benchmark...
[*] Compiling the test-instr-persist-shmem fuzzing harness for the benchmark to use.
[*] singlecore test-instr-persist-shmem run 1 of 2, execs/s: 124883.62
[*] singlecore test-instr-persist-shmem run 2 of 2, execs/s: 126704.93
[*] Average execs/sec for this test across all runs was: 125794.28
[*] Using 16 fuzzers for multicore fuzzing (use --fuzzers to override).
[*] multicore test-instr-persist-shmem run 1 of 2, execs/s: 1179822.66
[*] multicore test-instr-persist-shmem run 2 of 2, execs/s: 1175584.09
[*] Average execs/sec for this test across all runs was: 1177703.38
[*] Results have been written to the benchmark-results.jsonl file.
[*] Results have been written to the COMPARISON.md file.
```
By default, the script will use a number of parallel fuzzers equal to your
available CPUs/threads (change with `--fuzzers`), and will perform each test
three times and average the result (change with `--runs`).
The script will use multicore fuzzing instead of singlecore by default (change
with `--mode singlecore`) and use a persistent-mode shared memory harness for
optimal speed (change with `--target test-instr`).
Feel free to submit the resulting line for your CPU added to the COMPARISON.md
and benchmark-results.jsonl files back to AFL++ in a pull request.
Each run writes results to [benchmark-results.jsonl](benchmark-results.jsonl)
in [JSON Lines](https://jsonlines.org/) format, ready to be pulled in to other
tools such as [jq -cs](https://jqlang.github.io/jq/) or
[pandas](https://pandas.pydata.org/) for analysis.
## Data analysis
There is sample data in [benchmark-results.jsonl](benchmark-results.jsonl), and
a Jupyter notebook for exploring the results and suggesting their meaning at
[benchmark.ipynb](benchmark.ipynb).

This is the list of all noteworthy changes made in every public
release of the tool. See README.md for the general instruction manual.
### Version ++4.20c (release)
! A new forkserver communication model is now introduced. afl-fuzz is
backward compatible to old compiled targets if they are not built
for CMPLOG/Redqueen, but new compiled targets will not work with
old afl-fuzz versions!
! Recompile all targets that are instrumented for CMPLOG/Redqueen!
- AFL++ now supports up to 4 billion coverage edges, up from 6 million.
- New compile option: `make PERFORMANCE=1` - this will enable special
CPU dependent optimizations that make everything more performant - but
the binaries will likely won't work on different platforms. Also
enables a faster hasher if the CPU requirements are met.
- The persistent record feature (see config.h) was expanded to also
support replay, thanks to @quarta-qti !
- afl-fuzz:
- the new deterministic fuzzing feature is now activated by default,
deactivate with -z. Parameters -d and -D are ignored.
- small improvements to CMPLOG/redqueen
- workround for a bug with MOpt -L when used with -M - in the future
we will either remove or rewrite MOpt.
- fix for `-t xxx+` feature
- -e extension option now saves the queue items, crashes, etc. with the
extension too
- fixes for trimmming, correct -V time and reading stats on resume by eqv
thanks a lot!
- afl-cc:
- added collision free caller instrumentation to LTO mode. activate with
`AFL_LLVM_LTO_CALLER=1`. You can set a max depth to go through single
block functions with `AFL_LLVM_LTO_CALLER_DEPTH` (default 0)
- fixes for COMPCOV/LAF and most other modules
- fix for GCC_PLUGIN cmplog that broke on std::strings
- afl-whatsup:
- now also displays current average speed
- small bugfixes
- Fixes for aflpp custom mutator and standalone tool
- Minor edits to afl-persistent-config
- Prevent temporary files being left behind on aborted afl-whatsup
- More CPU benchmarks added to benchmark/
### Version ++4.10c (release)
- afl-fuzz:
- default power schedule is now EXPLORE, due a fix in fast schedules
explore is slightly better now.
- fixed minor issues in the mutation engine, thanks to @futhewo for
reporting!
- better deterministic fuzzing is now available, benchmarks have shown
to improve fuzzing. Enable with -D. Thanks to @kdsjZh for the PR!
- afl-cc:
- large rewrite by @SonicStark which fixes a few corner cases, thanks!
- LTO mode now requires llvm 12+
- workaround for ASAN with gcc_plugin mode
- instrumentation:
- LLVM 18 support, thanks to @devnexen!
- Injection (SQL, LDAP, XSS) fuzzing feature now available, see
`instrumentation/README.injections.md` how to activate/use/expand.
- compcov/LAF-intel:
- floating point splitting bug fix by @hexcoder
- due a bug in LLVM 17 integer splitting is disabled there!
- when splitting floats was selected, integers were always split as well,
fixed to require AFL_LLVM_LAF_SPLIT_COMPARES or _ALL as it should
- dynamic instrumentation filtering for LLVM NATIVE, thanks @Mozilla!
see utils/dynamic_covfilter/README.md
- qemu_mode:
- plugins are now activated by default and a new module is included that
produces drcov compatible traces for lighthouse/lightkeeper/...
thanks to @JRomainG to submitting!
- updated Nyx checkout (fixes a bug) and some QOL
- updated the custom grammar mutator
- document afl-cmin does not work on macOS (but afl-cmin.bash does)
### Version ++4.09c (release)
- afl-fuzz:
- fixed the new mutation implementation for two bugs
- added `AFL_FINAL_SYNC` which forces a final fuzzer sync (also for `-F`)
before terminating.
- added AFL_IGNORE_SEED_PROBLEMS to skip over seeds that time out instead
of exiting with an error message
- allow -S/-M naming up to 50 characters (from 24)
- CMPLOG:
- added scale support (-l S)
- skip unhelpful insertions (u8)
- added --version and --help command line parameters
- fixed endless loop when reading malformed dictionaries
- new custom mutator function: post_run - thanks to yangzao!
- afl-whatsup:
- detect instanced that are starting up and show them as such as not dead
- now also shows coverage reached
- option -m shows only very relevant stats
- option -n will not use color in the output
- instrumentation:
- fix for a few string compare transform functions for LAF
- we are instrumenting __cxx internal functions again. this might break
a few targets, please report if so.
- frida_mode:
- fixes support for large map offsets
- support for AFL_FUZZER_LOOPCOUNT for afl.rs and LLVMFuzzerTestOneInput
- afl-cmin/afl-cmin.bash: prevent unneeded file errors
- added new tool afl-addseeds that adds new seeds to a running campaign
- added benchmark/benchmark.py if you want to see how good your fuzzing
speed is in comparison to other setups.
### Version ++4.08c (release)
### Version ++4.08a (dev)
- afl-fuzz:
- new mutation engine: mutations that favor discovery more paths are
prefered until no new finds for 10 minutes then switching to mutations
@ -116,14 +15,10 @@
command line tool! See custom_mutators/aflpp/standalone/
- display the state of the fuzzing run in the UI :-)

<summary id="should-you-ever-stop-afl-fuzz-minimize-the-corpus-and-restart">Should you ever stop afl-fuzz, minimize the corpus and restart?</summary><p>
To stop afl-fuzz, minimize it's corpus and restart you would usually do:
```
Control-C # to terminate afl-fuzz
$ afl-cmin -T nproc -i out/default/queue -o minimized_queue -- ./target
$ AFL_FAST_CAL=1 AFL_CMPLOG_ONLY_NEW=1 afl-fuzz -i minimized_queue -o out2 [other options] -- ./target
```
If this improves fuzzing or not is debated and no consensus has been reached
or in-depth analysis been performed.
On the pro side:
* The queue/corpus is reduced (up to 20%) by removing intermediate paths
that are maybe not needed anymore.
On the con side:
* Fuzzing time is lost for the time the fuzzing is stopped, minimized and
restarted.
The the big question:
* Does a minimized queue/corpus improve finding new coverage or does it
hinder it?
The AFL++ team's own limited analysis seem to to show that keeping
intermediate paths help to find more coverage, at least for afl-fuzz.
For honggfuzz in comparison it is a good idea to restart it from time to
time if you have other fuzzers (e.g: AFL++) running in parallel to sync
the finds of other fuzzers to honggfuzz as it has no syncing feature like
AFL++ or libfuzzer.

## MacOS X on x86 and arm64 (M1)
macOS has some gotchas due to the idiosyncrasies of the platform.
MacOS has some gotchas due to the idiosyncrasies of the platform.
macOS supports SYSV shared memory used by AFL++'s instrumentation, but the
default settings aren't sufficient. Before even building, increase
them by running the provided script:
```shell
sudo afl-system-config
```
See
[https://www.spy-hill.com/help/apple/SharedMemory.html](https://www.spy-hill.com/help/apple/SharedMemory.html)
for documentation for the shared memory settings and how to make them permanent.
Next, to build AFL++, install the following packages from brew:
To build AFL, install llvm (and perhaps gcc) from brew and follow the general
instructions for Linux. If possible, avoid Xcode at all cost.
```shell
brew install wget git make cmake llvm gdb coreutils
```
Depending on your macOS system + brew version, brew may be installed in different places.
You can check with `brew info llvm` to know where, then create a variable for it:
Be sure to setup `PATH` to point to the correct clang binaries and use the
freshly installed clang, clang++, llvm-config, gmake and coreutils, e.g.:
```shell
export HOMEBREW_BASE="/opt/homebrew/opt"
```
# Depending on your MacOS system + brew version it is either
export PATH="/opt/homebrew/opt/llvm/bin:$PATH"
# or
export PATH="/usr/local/opt/llvm/bin:$PATH"
# you can check with "brew info llvm"
or
```shell
export HOMEBREW_BASE="/usr/local/opt"
```
Set `PATH` to point to the brew clang, clang++, llvm-config, gmake and coreutils.
Also use the brew clang compiler; the Xcode clang compiler must not be used.
```shell
export PATH="$HOMEBREW_BASE/coreutils/libexec/gnubin:/usr/local/bin:$HOMEBREW_BASE/llvm/bin:$PATH"
export PATH="/usr/local/opt/coreutils/libexec/gnubin:/usr/local/bin:$PATH"
export CC=clang
export CXX=clang++
gmake
cd frida_mode
gmake
cd ..
sudo gmake install
```
Then build following the general Linux instructions.
`afl-gcc` will fail unless you have GCC installed, but that is using outdated
instrumentation anyway. `afl-clang` might fail too depending on your PATH setup.
But you don't want neither, you want `afl-clang-fast` anyway :) Note that
`afl-clang-lto`, `afl-gcc-fast` and `qemu_mode` are not working on MacOS.
If everything worked, you should then have `afl-clang-fast` installed, which you can check with:
The crash reporting daemon that comes by default with MacOS X will cause
problems with fuzzing. You need to turn it off:
```shell
which afl-clang-fast
```
launchctl unload -w /System/Library/LaunchAgents/com.apple.ReportCrash.plist
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.ReportCrash.Root.plist
```
Note that `afl-clang-lto`, `afl-gcc-fast` and `qemu_mode` are not working on macOS.
The crash reporting daemon that comes by default with macOS will cause
problems with fuzzing. You need to turn it off, which you can do with `afl-system-config`.
The `fork()` semantics on macOS are a bit unusual compared to other unix systems
The `fork()` semantics on OS X are a bit unusual compared to other unix systems
and definitely don't look POSIX-compliant. This means two things:
- Fuzzing will be probably slower than on Linux. In fact, some folks report
considerable performance gains by running the jobs inside a Linux VM on
macOS.
MacOS X.
- Some non-portable, platform-specific code may be incompatible with the AFL++
forkserver. If you run into any problems, set `AFL_NO_FORKSRV=1` in the
environment before starting afl-fuzz.

works on both x86 and arm64 MacOS boxes.
MacOS X supports SYSV shared memory used by AFL's instrumentation, but the
default settings aren't usable with AFL++. The default settings on 10.14 seem to
be:
```bash
$ ipcs -M
IPC status from <running system> as of XXX
shminfo:
shmmax: 4194304 (max shared memory segment size)
shmmin: 1 (min shared memory segment size)
shmmni: 32 (max number of shared memory identifiers)
shmseg: 8 (max shared memory segments per process)
shmall: 1024 (max amount of shared memory in pages)
```
To temporarily change your settings to something minimally usable with AFL++,
run these commands as root:
```bash
sysctl kern.sysv.shmmax=8388608
sysctl kern.sysv.shmall=4096
```
If you're running more than one instance of AFL, you likely want to make
`shmall` bigger and increase `shmseg` as well:
```bash
sysctl kern.sysv.shmmax=8388608
sysctl kern.sysv.shmseg=48
sysctl kern.sysv.shmall=98304
```
