 # TODO list for AFL++
 
+## Must
+
+ - afl_fsrv_deinit cmplog
+ - ijon support?
+ - check for null ptr for xml/curl/g_ string transform functions
+ - 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
- - show in the UI when fuzzing is "done"
- - test cmplog for less than 16bit
+ - cmplog: add loop count resolving (byte -> loop cnt change, calc special values)
  - 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

+# 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).

+
+`AFL_CUSTOM_MUTATOR_LATE_SEND` - MUST be set!
+`CUSTOM_SEND_IP` - the IP address to send to (basically only 127.0.0.1 makes sense)
+`CUSTOM_SEND_PORT` - the TCP port to send to
+`CUSTOM_SEND_READ` - if the custom mutator should wait for a reply from the target
+
+Example:
+```
+CUSTOM_SEND_IP=127.0.0.1 CUSTOM_SEND_PORT=8000 CUSTOM_SEND_READ=1 AFL_CUSTOM_MUTATOR_LATE_SEND=1 AFL_CUSTOM_MUTATOR_LIBRARY=custom_send_tcp.so ./afl-fuzz ...

 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:

+    (thanks to @wtdcode !)
+  - afl-fuzz:

+
+### Version ++4.30c (release)
+  ! afl-gcc and afl-clang funcionality is now removed !
+  - afl-fuzz:
+    - fastresume feature added. if you abort fuzzing and resume fuzzing
+      with `-i -` or `AFL_AUTORESUME=1` and the target binary has not changed
+      then a dump will be loaded and the calibration phase skipped.
+      to disable this feature set `AFL_NO_FASTRESUME=1`
+      zlib compression is used if zlib is found at compile time
+    - 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 :-)
+  - frida_mode:
+    - AFL_FRIDA_PERSISTENT_ADDR can now be be any reachable address not just
+      a function entry

+      AFL type forkserver. Useful for symcc/symqemu/nautilus/etc. with
+      AFL_LLVM_INSTRUMENT=CLASSIC
+    - new compile time variable: `AFL_OPT_LEVEL` to set a specific optimization
+      level, default is `3`
+    - correctly explain how to get the correct map size for large targets
+    - small fix for weird LLVM defines in redhat
+  - code formatting updated to llvm 18
+  - improved custom_mutators/aflpp/standalone/aflpp-standalone

+
+### Version ++4.21c (release)
+  * afl-fuzz
+    - fixed a regression in afl-fuzz that resulted in a 5-10% performace loss
+      do a switch from gettimeofday() to clock_gettime() which should be rather
+      three times faster. The reason for this is unknown.
+    - new queue selection algorithm based on 2 core years of queue data
+      analysis. gives a noticable improvement on coverage although the results
+      seem counterintuitive :-)
+    - added AFL_DISABLE_REDUNDANT for huge queues
+    - added `AFL_NO_SYNC` environment variable that does what you think it does
+    - fix AFL_PERSISTENT_RECORD
+    - run custom_post_process after standard trimming
+    - prevent filenames in the queue that have spaces
+    - minor fix for FAST schedules
+    - more frequent stats update when syncing (todo: check performance impact)
+    - now timing of calibration, trimming and syncing is measured seperately,
+      thanks to @eqv!
+    - -V timing is now accurately the fuzz time (without syncing), before
+      long calibration times and syncing could result in now fuzzing being
+      made when the time was already run out until then, thanks to @eqv!
+    - fix -n uninstrumented mode when ending fuzzing
+    - enhanced the ASAN configuration
+    - make afl-fuzz use less memory with cmplog and fix a memleak

+
+### 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
+  - custom mutators:
+    - fixes for aflpp custom mutator and standalone tool
+    - important fix to the symcc custom mutator
+  - 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!

+    - 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

+      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

+  - 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)
+  - afl-fuzz:
+    - new mutation engine: mutations that favor discovery more paths are
+      prefered until no new finds for 10 minutes then switching to mutations
+      that favor triggering crashes. Modes and switch time can be configured
+      with `-P`. Also input mode for the target can be defined with `-a` to
+      be `text` or `binary` (defaults to `generic`)
+    - new custom mutator that has the new afl++ engine (so it can easily
+      incorporated into new custom mutators), and also comes with a standalone
+      command line tool! See custom_mutators/aflpp/standalone/
+    - display the state of the fuzzing run in the UI :-)
+    - fix timeout setting if '+' is used or a session is restarted
+    - -l X option to enable base64 transformation solving
+    - allow to disable CMPLOG with '-c -' (e.g. afl.rs enforces '-c 0' on
+      every instance which is counterproductive).
+  - afl-cmin/afl-cmin.bash:
+    - fixed a bug inherited from vanilla AFL where a coverage of
+      map[123] = 11 would be the same as map[1123] = 1
+    - warn on crashing inputs
+    - adjust threads if less inputs than threads specified
+  - afl-cc:
+    - fixed an off-by-one instrumentation of iselect, hurting coverage a bit.
+      Thanks to @amykweon for spotting and fixing!
+    - @toka fixed a bug in laf-intel signed integer comparison splitting,
+      thanks a lot!!
+    - more LLVM compatability
+  - frida_mode:
+    - support for long form instrumentation on x86_x64 and arm64
+    - renamed utils/get_symbol_addr.sh to utils/frida_get_symbol_addr.sh
+  - qemu_mode:
+    - added qemu_mode/utils/qemu_get_symbol_addr.sh

+# 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.
