 # TODO list for AFL++
 
+## Must
+
+ - UI revamp
+ - hardened_usercopy=0 page_alloc.shuffle=0
+ - add value_profile but only enable after 15 minutes without finds
+ - cmplog max len, cmplog max items envs?
+ - 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
+ - problem: either -L0 and/or -p mmopt results in zero new coverage
+
+
 ## 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
@@ -25,8 +38,7 @@ QEMU mode/FRIDA mode:

  - rename qemu specific envs to AFL_QEMU (AFL_ENTRYPOINT, AFL_CODE_START/END,

+# 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 ++4.08a (dev)
+### 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.

+  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

+    * Does a minimized queue/corpus improve finding new coverage or does it

+
+  The AFL++ team's own limited analysis seem to to show that keeping

+# Injection fuzzing
+
+Coverage guided fuzzing so far is only able to detect crashes, so usually
+memory corruption issues, or - if implemented by hand in the harness -
+invariants.
+
+This is a proof-of-concept implementation to additionally hunt for injection
+vulnerabilities.
+It works by instrumenting calls to specific functions and parsing the
+query parameter for a specific unescaped dictionary string, and if detected,
+crashes the target.
+
+This has a very low false positive rate.
+But obviously this can only find injection vulnerailities that are suspectible
+to this specific (but most common) issue. Hence in a rare kind of injection
+vulnerability this won't find the bug - and be a false negative.
+But this can be tweaked by the user - see the HOW TO MODIFY section below.
+
+## How to use
+
+Set one or more of the following environment variables for **compiling**
+the target and - *this is important* - when **fuzzing** the target:
+
+ - `AFL_LLVM_INJECTIONS_SQL`
+ - `AFL_LLVM_INJECTIONS_LDAP`
+ - `AFL_LLVM_INJECTIONS_XSS`
+
+Alternatively you can set `AFL_LLVM_INJECTIONS_ALL` to enable all.
+
+## How to modify
+
+If you want to add more fuctions to check for e.g. SQL injections:
+Add these to `instrumentation/injection-pass.cc` and recompile.
+
+If you want to test for more injection inputs:
+Add the dictionary tokens to `src/afl-fuzz.c` and the check for them to
+`instrumentation/afl-compiler-rt.o.c`.
+
+If you want to add new injection targets:
+You will have to edit all three files.
+
+Just search for:
+```
+// Marker: ADD_TO_INJECTIONS
+```
+in the files to see where this needs to be added.
+
+**NOTE:** pull requests to improve this feature are highly welcome :-)

 special way:
