-## How to contribute to the docs
-
-We welcome contributions to our docs.
-
-Before creating a new file, please check if your content matches an existing
-file in one the following folders:
-
-* [docs/](docs/) (this is where you can find most of our docs content)
-* [frida_mode/](frida_mode/)
-* [instrumentation/](instrumentation/)
-* [qemu_mode/](qemu_mode/)
-* [unicorn_mode/](unicorn_mode/)
-
-When working on the docs, please keep the following guidelines in mind:
-
-* Edit or create Markdown files and use Markdown markup.
-  * Do: fuzzing_gui_program.md
-  * Don't: fuzzing_gui_program.txt
-* Use underscore in file names.
-  * Do: fuzzing_network_service.md
-  * Don't: fuzzing-network-service.md
-* Use a maximum of 80 characters per line to make reading in a console easier.
-* Make all pull requests against `dev`, see
-  [#how-to-submit-a-pull-request-to-afl](#how-to-submit-a-pull-request-to-afl).
-
-And finally, here are some best practices for writing docs content:
-
-* Use clear and simple language.
-* Structure your content with headings and paragraphs.
-* Use bulleted lists to present similar content in a way that makes it easy to
-  scan.
-* Use numbered lists for procedures or prioritizing.
-* Link to related content, for example, prerequisites or in-depth discussions.
+Remember that AFLplusplus has to build and run on many platforms, so
+generalize your Makefiles/GNUmakefile (or your patches to our pre-existing
+Makefiles) to be as generic as possible.

 # TODO list for AFL++
 
-## Must
+## Roadmap 3.00+
 
- - fast restart of afl-fuzz if cmdline + target hash is the same
- - 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
- - 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
+ - AFL_MAP_SIZE for qemu_mode and unicorn_mode
+ - CPU affinity for many cores? There seems to be an issue > 96 cores
  - afl-plot to support multiple plot_data
- - parallel builds for source-only targets
- - get rid of check_binary, replace with more forkserver communication
- - first fuzzer should be a main automatically? not sure.
-
-## Maybe
-
- - forkserver tells afl-fuzz if cmplog is supported and if so enable
-   it by default, with AFL_CMPLOG_NO=1 (?) set to skip?
- - afl_custom_splice()
- - cmdline option from-to range for mutations
+ - afl_custom_fuzz_splice_optin()
+ - intel-pt tracer
 
 ## Further down the road
 
-QEMU mode/FRIDA mode:
+afl-fuzz:
+ - setting min_len/max_len/start_offset/end_offset limits for mutation output
+ - add __sanitizer_cov_trace_cmp* support via shmem
+
+llvm_mode:
+ - add __sanitizer_cov_trace_cmp* support
+
+qemu_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 we have
+   persistent mode
+ - add/implement AFL_QEMU_INST_LIBLIST and AFL_QEMU_NOINST_PROGRAM
+ - add/implement AFL_QEMU_INST_REGIONS as a list of _START/_END addresses
 
 ## Ideas
 
  - LTO/sancov: write current edge to prev_loc and use that information when
-   using cmplog or __sanitizer_cov_trace_cmp*. maybe we can deduct by follow up
-   edge numbers that both following cmp paths have been found and then disable
-   working on this edge id -> cmplog_intelligence branch
- - use cmplog colorization taint result for havoc locations?
+   using cmplog or __sanitizer_cov_trace_cmp*. maybe we can deduct by follow
+   up edge numbers that both following cmp paths have been found and then
+   disable working on this edge id -> cmplog_intelligence branch

-                        (you should have built afl-plot-ui to use this option)
+The afl_state_dir parameter should point to an existing state directory for any
+active or stopped instance of afl-fuzz; while graph_output_dir should point to
+an empty directory where this tool can write the resulting plots to.
 
 The program will put index.html and three PNG images in the output directory;
 you should be able to view it with any web browser of your choice.

-# 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++ CoreSight mode
-
-CoreSight mode enables binary-only fuzzing on ARM64 Linux using CoreSight (ARM's hardware tracing technology).
-
-NOTE: CoreSight mode is in the early development stage. Not applicable for production use.
-Currently the following hardware boards are supported:
-* NVIDIA Jetson TX2 (NVIDIA Parker)
-* NVIDIA Jetson Nano (NVIDIA Tegra X1)
-* GIGABYTE R181-T90 (Marvell ThunderX2 CN99XX)
-
-## Getting started
-
-Please read the [RICSec/coresight-trace README](https://github.com/RICSecLab/coresight-trace/blob/master/README.md) and check the prerequisites (capstone) before getting started.
-
-CoreSight mode supports the AFL++ fork server mode to reduce `exec` system call
-overhead. To support it for binary-only fuzzing, it needs to modify the target
-ELF binary to re-link to the patched glibc. We employ this design from
-[PTrix](https://github.com/junxzm1990/afl-pt).
-
-Check out all the git submodules in the `cs_mode` directory:
-
-```bash
-git submodule update --init --recursive
-```
-
-### Build coresight-trace
-
-There are some notes on building coresight-trace. Refer to the [README](https://github.com/RICSecLab/coresight-trace/blob/master/README.md) for the details. Run make in the `cs_mode` directory:
-
-```bash
-make build
-```
-
-Make sure `cs-proxy` is placed in the AFL++ root directory as `afl-cs-proxy`.
-
-### Patch COTS binary
-
-The fork server mode requires patchelf and the patched glibc. The dependency build can be done by just run make:
-
-```bash
-make patch TARGET=$BIN
-```
-
-The above make command builds and installs the dependencies to `$PREFIX` (default to `$PWD/.local`) at the first time. Then, it runs `patchelf` to `$BIN` with output `$OUTPUT` (`$BIN.patched` by default).
-
-### Run afl-fuzz
-
-Run `afl-fuzz` with `-A` option to use CoreSight mode.
-
-```bash
-sudo afl-fuzz -A -i input -o output -- $OUTPUT @@
-```
-
-## Environment Variables
-
-There are AFL++ CoreSight mode-specific environment variables for run-time configuration.
-
-* `AFL_CS_CUSTOM_BIN` overrides the proxy application path. `afl-cs-proxy` will be used if not defined.
-
-* `AFLCS_COV` specifies coverage type on CoreSight trace decoding. `edge` and `path` is supported. The default value is `edge`.
-* `AFLCS_UDMABUF` is the u-dma-buf device number used to store trace data in the DMA region. The default value is `0`.
-
-## TODO List
-
-* Eliminate modified glibc dependency
-* Support parallel fuzzing
-
-## Acknowledgements
-
-This project has received funding from the Acquisition, Technology & Logistics Agency (ATLA) under the National Security Technology Research Promotion Fund 2021 (JPJ004596).

-# An AFL++ custom mutator using TritonDSE
-
-## Installing the requirements

-## How to run with an example
-
-```
-../../afl-cc -o ../../test-instr ../../test-instr.c
-mkdir -p in
-echo aaaa > in/in
-AFL_DISABLE_TRIM=1 AFL_CUSTOM_MUTATOR_ONLY=1 AFL_SYNC_TIME=1 AFL_PYTHON_MODULE=aflpp_tritondse PYTHONPATH=. ../../afl-fuzz -i in -o out -- ../../test-instr
-```
-
-Note that this custom mutator works differently, new finds are synced
-after 10-60 seconds to the fuzzing instance. This is necessary because only
-C/C++ custom mutators have access to the internal AFL++ state.
-
-Note that you should run first with `AFL_DEBUG` for 5-10 minutes and see if
-all important libraries and syscalls are hooked (look at `WARNING` and `CRITICAL`
-output during the run, best use with `AFL_NO_UI=1`)

-# ATNwalk: Grammar-Based Fuzzing using Only Bit-Mutations
-
-This is a custom mutator integration of ATNwalk that works by communicating via UNIX domain sockets.
-
-Refer to [https://github.com/atnwalk/testbed](https://github.com/atnwalk/testbed) for detailed instructions on how to get ATNwalk running.
-
-## Build
-
-Just type `make` to build `atnwalk.so`.
-
-## Run
-
-**NOTE:** The commands below just demonstrate an example how running ATNwalk looks like and require a working [testbed](https://github.com/atnwalk/testbed)
-
-```bash
-# create the required a random seed first
-mkdir -p ~/campaign/example/seeds
-cd ~/campaign/example/seeds
-head -c1 /dev/urandom | ~/atnwalk/build/javascript/bin/decode -wb > seed.decoded 2> seed.encoded
-
-# create the required atnwalk directory and copy the seed
-cd ../
-mkdir -p atnwalk/in
-cp ./seeds/seed.encoded atnwalk/in/seed
-cd atnwalk
-
-# assign to a single core when benchmarking it, change the CPU number as required
-CPU_ID=0
-
-# start the ATNwalk server
-nohup taskset -c ${CPU_ID} ${HOME}/atnwalk/build/javascript/bin/server 100 > server.log 2>&1 &

-# Autotokens
-
-This implements an improved autotoken grammar fuzzing idea presented in
-[Token-Level Fuzzing][https://www.usenix.org/system/files/sec21-salls.pdf].
-It is a grammar fuzzer without actually knowing the grammar, but only works
-with text based inputs.
-
-It is recommended to run with together in an instance with `CMPLOG`.
-
-If you have a dictionary (`-x`) this improves this custom grammar mutator.
-
-If **not** running with `CMPLOG`, it is possible to set
-`AFL_CUSTOM_MUTATOR_ONLY` to concentrate on grammar bug classes.
-
-Do **not** set `AFL_DISABLE_TRIM` with this custom mutator!
-
-## Configuration via environment variables
-
-`AUTOTOKENS_ONLY_FAV` - only use this mutator on favorite queue items
-`AUTOTOKENS_COMMENT` - what character or string starts a comment which will be
-                       removed. Default: `/* ... */`
-`AUTOTOKENS_FUZZ_COUNT_SHIFT` - reduce the number of fuzzing performed, shifting
-                                the value by this number, e.g. 1.
-`AUTOTOKENS_AUTO_DISABLE` - disable this module if the seeds are not ascii
-                            (or no input and no (ascii) dictionary)
-`AUTOTOKENS_LEARN_DICT` - learn from dictionaries?
-                          0 = none
-                          1 = only -x or autodict
-                          2 = -x, autodict and `CMPLOG`
-`AUTOTOKENS_CHANGE_MIN` - minimum number of mutations (1-256, default 8)
-`AUTOTOKENS_CHANGE_MAX` - maximum number of mutations (1-4096, default 64)
-`AUTOTOKENS_CREATE_FROM_THIN_AIR` - if only one small start file is present and
-                                    a dictionary loaded then create one initial
-                                    structure based on the dictionary.

-# GramaTron
-
-GramaTron is a coverage-guided fuzzer that uses grammar automatons to perform
-grammar-aware fuzzing.  Technical details about our framework are available in
-the [ISSTA'21 paper](https://nebelwelt.net/files/21ISSTA.pdf). The artifact to
-reproduce the experiments presented in the paper are present in `artifact/`.
-Instructions to run a sample campaign and incorporate new grammars is presented
-below:
-
-## Compiling
-
-Execute `./build_gramatron_mutator.sh`.
-
-## Running
-
-You have to set the grammar file to use with `GRAMATRON_AUTOMATION`:
-
-```
-export AFL_DISABLE_TRIM=1
-export AFL_CUSTOM_MUTATOR_ONLY=1
-export AFL_CUSTOM_MUTATOR_LIBRARY=./gramatron.so
-export GRAMATRON_AUTOMATION=grammars/ruby/source_automata.json
-afl-fuzz -i in -o out -- ./target
-```
-
-## Adding and testing a new grammar
-
-- Specify in a JSON format for CFG. Examples are correspond `source.json` files.
-- Run the automaton generation script (in `src/gramfuzz-mutator/preprocess`)
-  which will place the generated automaton in the same folder.
-
-  ```
-  ./preprocess/prep_automaton.sh <grammar_file> <start_symbol> [stack_limit]
-
-  E.g., ./preprocess/prep_automaton.sh ~/grammars/ruby/source.json PROGRAM
-  ```
-
-- If the grammar has no self-embedding rules, then you do not need to pass the
-  stack limit parameter. However, if it does have self-embedding rules, then you
-  need to pass the stack limit parameter. We recommend starting with `5` and
-  then increasing it if you need more complexity.
-- To sanity-check that the automaton is generating inputs as expected, you can
-  use the `test` binary housed in `src/gramfuzz-mutator`.
-
-  ```
-  ./test SanityCheck <automaton_file>
-
-  E.g., ./test SanityCheck ~/grammars/ruby/source_automata.json
-  ```
