 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.

+# 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_SAN_NO_INST=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_SAN_NO_INST=1 AFL_USE_UBSAN=1 AFL_USE_ASAN=1 afl-clang-fast test-instr.c -o ./asanubsan
+AFL_SAN_NO_INST=1 AFL_USE_MSAN=1 afl-clang-fast test-instr.c -o ./msan
+```
+
+Do note `AFL_SAN_NO_INST=1` is crucial, this enables forkservers but disables pc instrumentation. Do not reuse sanitizers-enabled binaries built _without_ `AFL_SAN_NO_INST=1`. This will mess up SAND execution pattern.
+
+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.
