These bindings are documented with rustdoc. To view the documentation run

```cargo doc -p custom_mutator --open```.

A minimal example can be found in `example`. Build it using `cargo build --example example_mutator`.
|
||||
|
||||
An example using [lain](https://github.com/microsoft/lain) for structured fuzzing can be found in `example_lain`.
|
||||
Since lain requires a nightly rust toolchain, you need to set one up before you can play with it.
|
||||
|
||||
An example for the use of the post_process function, using [lain](https://github.com/microsoft/lain) with [serde](https://github.com/serde-rs/serde) and [bincode](https://github.com/bincode-org/bincode) can be found in `example_lain_post_process`.
|
||||
In order for it to work you need to:
|
||||
|
||||
- disable input trimming with `AFL_DISABLE_TRIM=1`
|
||||
- provide an initial instance serialized with `bincode` or use the `AFL_NO_STARTUP_CALIBRATION=1` environment variable.
|
||||
|
||||
Note that `bincode` can also be used to serialize/deserialize the lain-generated structure and mutate it rather than generating a new one at each iteration, but it requires some structure serialized with `bincode` as input seed.

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 ++4.33a (dev)
|
||||
- afl-fuzz:
|
||||
- Use `AFL_PRELOAD_DISCRIMINATE_FORKSERVER_PARENT` if you use AFL_PRELOAD
|
||||
to disable fork, see docs (thanks to @alexandredoyen29)
|
||||
- Fix for FAST power schedules (introduced in 4.32c) (thanks to @kcwu)
|
||||
- Colors for NO_UI output (thanks to @smoelius)
|
||||
- Fix potential sync issues when resuming sessions and when instances in a
|
||||
campaign are restarted and skip entries that were synced from itself
|
||||
(thanks to @kcwu for raising the issues and providing support!)
|
||||
- more 64 bit archicture support by @maribu
|
||||
- afl-cc:
|
||||
- Added instrumenting hidden edges (approx 5% edges were not instrumented,
|
||||
LLVM sancov overall misses 8% of edges compared to our implementation)
|
||||
Note that is is currently only implemented for our PCGUARD plugin, not
|
||||
LTO, CLASSIC, etc.!
|
||||
- Fix to make AFL_SAN_NO_INST work with gcc_plugin
|
||||
- MacOS aflpp driver compilation fix (-fsanitize=fuzzer implementation)
|
||||
- Make AFL_DUMP_MAP_SIZE work even if the target has sanitizer issues
|
||||
- qemuafl:
|
||||
- Better MIPS persistent mode support
|
||||
- afl-cmin:
|
||||
- New afl-cmin.py which is much faster, will be executed by default via
|
||||
afl-cmin if it executes successfully (thanks to @kcwu!)
|
||||
- New desocketing library: utils/libaflppdesock
|
||||
- Likely works when all other desocketing options fail
|
||||
|
||||
|
||||
### Version ++4.32c (release)
|
||||
- Fixed a bug where after a fast restart of a full fuzzed corpus afl-fuzz
|
||||
terminates with "need at least one valid input seed that does not crash"
|
||||
- Small improvements to afl-*-config
|
||||
- afl-fuzz:
|
||||
- memory leak fixes by @kcwu - thanks!
|
||||
- many more nits and small memory saves thanks to @kcwu
|
||||
- remove deprecated files from queue/.state
|
||||
- fix bitmap update function if no current trace is present
|
||||
- fix for afl_custom_queue_get
|
||||
- various small nits
|
||||
- afl-cc:
|
||||
- fix pass support for LLVM 20 (passes were run too early)
|
||||
- dropped plugin support for LLVM 13
|
||||
- fix AFL_OLD_FORKSERVER
|
||||
- various minor fixes
|
||||
- frida_mode:
|
||||
- fixes for new MacOS + M4 hardware
|
||||
|
||||
### Version ++4.31c (release)
|
||||
- SAND mode added (docs/SAND.md) for more effecient fuzzing with sanitizers
|
||||
(thanks to @wtdcode !)
|
||||
- afl-fuzz:
|
||||
- splicing phase is now DISABLED by default because research showed
|
||||
it is counterproductive. New command line parameter `-u` to enable
|
||||
it.
|
||||
- Python 3.13+ support
|
||||
- loose file and shared memory permissions on Android and iPhone
|
||||
- afl-cc:
|
||||
- LLVM 20 support (again - please don't change the API all the time ...)
|
||||
- -fsanitize=fuzzer now inserts libAFLDriver.a addtionally early to help
|
||||
compiling if LLVMFuzzerTestOneOnput is in an .a archive
|
||||
- added __sanitizer_weak_hook_* functions (in case that is helpful in
|
||||
weird setups)
|
||||
- fix bug with large map sizes when multiple libraries are loaded after
|
||||
the shared memory was obtained.
|
||||
|
||||
### Version ++4.30c (release)
|
||||
! afl-gcc and afl-clang funcionality is now removed !
|
||||
### Version ++4.22a (dev)

- improved seed selection algorithm
|
||||
- added `AFL_CUSTOM_MUTATOR_LATE_SEND=1` to call the custom send()
|
||||
function after the target has been restarted.
|
||||
- because of bad math and undefined behaviour fixes we have to change
|
||||
the CMPLOG map. **YOU NEED TO RECOMPILE CMPLOG TARGETS**
|
||||
- fixed custom_post_process for calibration
|
||||
- fixes for AFL_EXIT_ON_TIME and AFL_EXIT_WHEN_DONE, changed behaviour of
|
||||
AFL_EXIT_WHEN_DONE to finish when really done :-)

To compile directly on a jailbroken iOS device, it is recommended to use a jailbreak that supports Procursus,
|

as Procursus provides up-to-date pre-built packages for the required tools.
|
||||
|
||||
Ensure `openssh` is installed on your iOS device, then SSH into it.

|
||||
```shell
|

sudo apt install wget git make cmake clang gawk llvm ldid coreutils build-essential xz-utils
|

```
|

```shell

export IOS_SDK_PATH="/usr/share/SDKs/iPhoneOS.sdk"
|

export CC=clang

```
|

Then build following the general Linux instructions.
|
||||
|
||||
**Option 2: Cross-Compilation on macOS for Jailbroken iOS**
|
||||
|
||||
In addition to the packages required for a macOS build, install `ldid` for signing binaries:
|
||||
|
||||
```shell
|
||||
brew install ldid-procursus
|
||||
```

Configure the environment for compilation:

|
||||
export HOST_CC=cc

# SAND: Decoupling Sanitization from Fuzzing for Low Overhead
|
||||
|
||||
- Authors: Ziqiao Kong, Shaohua Li, Heqing Huang, Zhendong Su
|
||||
- Maintainer: [Ziqiao Kong](https://github.com/wtdcode)
|
||||
- Preprint: [arXiv](https://arxiv.org/abs/2402.16497), accepted by ICSE 2025
|
||||
- Main repo (for paper, reproduction, reference or cite): https://github.com/wtdcode/sand-aflpp
|
||||
|
||||
## Motivation
|
||||
|
||||
SAND introduces a new fuzzing workflow that can greatly reduce (or even eliminate) sanitizer overhead and combine different sanitizers in one fuzzing campaign.
|
||||
|
||||
The key point of SAND is that: sanitizing all inputs is wasting fuzzing power, because bug-triggering inputs are extremely rare (~1%). Obviously, not all inputs worth going through sanitizers. Therefore, if we can somehow "predict" if an input could trigger bugs (defined as "execution pattern"), we could greatly save fuzzing power by only sanitizing a small proportion of all inputs. That's exactly how SAND works.
|
||||
|
||||
## Usage
|
||||
|
||||
For a normal fuzzing workflow, we have:
|
||||
|
||||
1. Build target project with AFL_USE_ASAN=1 to get `target_asan`
|
||||
2. Fuzz the target with `afl-fuzz -i seeds -o out -- ./target_asan`
|
||||
|
||||
For SAND fuzzing workflow, this is slightly different:
|
||||
|
||||
1. Build target project _without_ any sanitizers to get `target_native`, which we will define as a "native binary". It is usually done by using `afl-clang-fast/lto(++)` to compile your project _without_ `AFL_USE_ASAN/UBSAN/MSAN`.
|
||||
2. Build target project with AFL_USE_ASAN=1 AFL_LLVM_ONLY_FSRV=1 to get `target_asan`. Do note this step can be repeated for multiple sanitizers, like MSAN, UBSAN etc. It is also possible to have ASAN and UBSAN to build together.
|
||||
3. Fuzz the target with `afl-fuzz -i seeds -o out -w ./target_asan -- ./target_native`. Note `-w` can be specified multiple times.
|
||||
|
||||
Then you get:
|
||||
|
||||
- almost the same performance as `afl-fuzz -i seeds -o out -- ./target_native`
|
||||
- and the same bug-finding capability as `afl-fuzz -i seeds -o out -- ./target_asan`
|
||||
|
||||
## Example Workflow
|
||||
|
||||
Take [test-instr.c](../test-instr.c) as an example.
|
||||
|
||||
1. Build the native binary
|
||||
|
||||
```bash
|
||||
afl-clang-fast test-instr.c -o ./native
|
||||
```
|
||||
|
||||
Just like the normal building process, except using `afl-clang-fast`
|
||||
|
||||
2. Build the sanitizers-enabled binaries.
|
||||
|
||||
```bash
|
||||
AFL_LLVM_ONLY_FSRV=1 AFL_USE_UBSAN=1 AFL_USE_ASAN=1 afl-clang-fast test-instr.c -o ./asanubsan
|
||||
AFL_LLVM_ONLY_FSRV=1 AFL_USE_MSAN=1 afl-clang-fast test-instr.c -o ./msan
|
||||
```
|
||||
|
||||
Do note `AFL_LLVM_ONLY_FSRV=1` is crucial, this enables forkservers but disables pc instrumentation. You are allowed to reuse sanitizers-enabled binaries, i.e. binaries built _without_ `AFL_LLVM_ONLY_FSRV=1`, at a cost of reduced speed.
|
||||
|
||||
3. Start fuzzing
|
||||
|
||||
```bash
|
||||
mkdir /tmp/test
|
||||
echo "a" > /tmp/test/a
|
||||
AFL_NO_UI=1 AFL_SKIP_CPUFREQ=1 afl-fuzz -i /tmp/test -o /tmp/out -w ./asanubsan -w ./msan -- ./native @@
|
||||
```
|
||||
|
||||
That's it!
|
||||
|
||||
## Tips
|
||||
|
||||
### Alternative execution patterns
|
||||
|
||||
By default, SAND uses the hash value of the simplified coverage map as execution pattern, i.e. if an input has a unique simplefied coverage map, it will be sent to sanitizers for inspection. This shall work for most cases. However, if you are strongly worried about missing bugs, try `AFL_SAN_ABSTRACTION=unique_trace afl-fuzz ...`, which filters inputs having a _unique coverage map_. Do note this significantly increases the number of inputs by 4-10 times, leading to much lower throughput. Alternatively, SAND also supports `AFL_SAN_ABSTRACTION=coverage_increase`, which essentially equals to running sanitizers on the corpus and thus having almost zero overhead, but at a cost of missing ~15% bugs in our evaluation.
|
||||
|
||||
### Run as many sanitizers as possible
|
||||
|
||||
Though we just used ASAN as an example, SAND works best if you provide more sanitizers, for example, UBSAN and MSAN.
|
||||
|
||||
You might do it via `afl-fuzz -i seeds -o out -w ./target_asan -w ./target_msan -w ./target_ubsan -- ./target_native`. Don't worry about the slow sanitizers like MSAN, SAND could still run very fast because only rather a few inputs are sanitized.
|
||||
|
||||
### Bugs types
|
||||
|
||||
The execution pattern evaluated in our papers is targeting the common bugs, as ASAN/MSAN/UBSAN catches. For other bug types, you probably need to define new execution patterns and re-evaluate.
|
||||
|
||||
### My throughput is greatly impacted
|
||||
|
||||
Generally, this is due to too many inputs going through sanitizers, for example, because of unstable targets. You could check stats from `plot_file` to confirm this. Try to switch execution patterns as stated above.

This file houses the assembly-level instrumentation injected into fuzzed
|
||||
programs. The instrumentation stores XORed pairs of data: identifiers of the
|
||||
currently executing branch and the one that executed immediately before.
|
||||
|
||||
TL;DR: the instrumentation does shm_trace_map[cur_loc ^ prev_loc]++
|
||||
|
||||
The code is designed for 32-bit and 64-bit x86 systems. Both modes should
|
||||
work everywhere except for Apple systems. Apple does relocations differently
|
||||
from everybody else, so since their OSes have been 64-bit for a longer while,
|
||||
I didn't go through the mental effort of porting the 32-bit code.
|
||||
|
||||
In principle, similar code should be easy to inject into any well-behaved
|
||||
binary-only code (e.g., using DynamoRIO). Conditional jumps offer natural
|
||||
targets for instrumentation, and should offer comparable probe density.

Performances notes
|
||||
------------------
|
||||
|
||||
Contributions to make this code faster are appreciated! Here are some
|
||||
rough notes that may help with the task:
|
||||
|
||||
- Only the trampoline_fmt and the non-setup __afl_maybe_log code paths are
|
||||
really worth optimizing; the setup / fork server stuff matters a lot less
|
||||
and should be mostly just kept readable.
|
||||
|
||||
- We're aiming for modern CPUs with out-of-order execution and large
|
||||
pipelines; the code is mostly follows intuitive, human-readable
|
||||
instruction ordering, because "textbook" manual reorderings make no
|
||||
substantial difference.
|
||||
|
||||
- Interestingly, instrumented execution isn't a lot faster if we store a
|
||||
variable pointer to the setup, log, or return routine and then do a reg
|
||||
call from within trampoline_fmt. It does speed up non-instrumented
|
||||
execution quite a bit, though, since that path just becomes
|
||||
push-call-ret-pop.
|
||||
|
||||
- There is also not a whole lot to be gained by doing SHM attach at a
|
||||
fixed address instead of retrieving __afl_area_ptr. Although it allows us
|
||||
to have a shorter log routine inserted for conditional jumps and jump
|
||||
labels (for a ~10% perf gain), there is a risk of bumping into other
|
||||
allocations created by the program or by tools such as ASAN.
|
||||
|
||||
- popf is *awfully* slow, which is why we're doing the lahf / sahf +
|
||||
overflow test trick. Unfortunately, this forces us to taint eax / rax, but
|
||||
this dependency on a commonly-used register still beats the alternative of
|
||||
using pushf / popf.
|
||||
|
||||
One possible optimization is to avoid touching flags by using a circular
|
||||
buffer that stores just a sequence of current locations, with the XOR stuff
|
||||
happening offline. Alas, this doesn't seem to have a huge impact:
|
||||
|
||||
https://groups.google.com/d/msg/afl-users/MsajVf4fRLo/2u6t88ntUBIJ
|
||||
|
||||
- Preforking one child a bit sooner, and then waiting for the "go" command
|
||||
from within the child, doesn't offer major performance gains; fork() seems
|
||||
to be relatively inexpensive these days. Preforking multiple children does
|
||||
help, but badly breaks the "~1 core per fuzzer" design, making it harder to
|
||||
scale up. Maybe there is some middle ground.
|
||||
|
||||
Perhaps of note: in the 64-bit version for all platforms except for Apple,
|
||||
the instrumentation is done slightly differently than on 32-bit, with
|
||||
__afl_prev_loc and __afl_area_ptr being local to the object file (.lcomm),
|
||||
rather than global (.comm). This is to avoid GOTRELPC lookups in the critical
|
||||
code path, which AFAICT, are otherwise unavoidable if we want gcc -shared to
|
||||
work; simple relocations between .bss and .text won't work on most 64-bit
|
||||
platforms in such a case.
|
||||
|
||||
(Fun fact: on Apple systems, .lcomm can segfault the linker.)
|
||||
|
||||
The side effect is that state transitions are measured in a somewhat
|
||||
different way, with previous tuple being recorded separately within the scope
|
||||
of every .c file. This should have no impact in any practical sense.
|
||||
|
||||
Another side effect of this design is that getenv() will be called once per
|
||||
every .o file when running in non-instrumented mode; and since getenv() tends
|
||||
to be optimized in funny ways, we need to be very careful to save every
|
||||
oddball register it may touch.

american fuzzy lop++ - hashing function
|
||||
---------------------------------------
|
||||
|
||||
The hash32() function is a variant of MurmurHash3, a good
|
||||
non-cryptosafe hashing function developed by Austin Appleby.
|
||||
|
||||
For simplicity, this variant does *NOT* accept buffer lengths
|
||||
that are not divisible by 8 bytes. The 32-bit version is otherwise
|
||||
similar to the original; the 64-bit one is a custom hack with
|
||||
mostly-unproven properties.
|
||||
|
||||
Austin's original code is public domain.
