 # TODO list for AFL++
 
+## Must
+
+ - 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
- - 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
@@ -25,8 +39,7 @@ QEMU mode/FRIDA mode:
  - non colliding instrumentation
  - 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 ++4.21c (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
+  * afl-cc:
+    - re-enable i386 support that was accidently disabled
+    - fixes for LTO and outdated afl-gcc mode for i386
+    - fix COMPCOV split compare for old LLVMs
+    - disable xml/curl/g_ string transform functions because we do not check
+      for null pointers ... TODO
+    - ensure shared memory variables are visible in weird build setups
+    - compatability to new LLVM 19 changes
+  * afl-cmin
+    - work with input files that have a space
+  * afl-showmap
+    - fix memory leak on shmem testcase usage (thanks to @ndrewh)
+    - minor fix to collect coverage -C (thanks to @bet4it)
+  * Fixed a shmem mmap bug (that rarely came up on MacOS)
+  * libtokencap: script generate_libtoken_dict.sh added by @a-shvedov

+
+### 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

+  - More CPU benchmarks added to benchmark/
+
+### Version ++4.10c (release)

+    - 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

+      - due a bug in LLVM 17 integer splitting is disabled there!
+      - when splitting floats was selected, integers were always split as well,

+      of exiting with an error message
+    - allow -S/-M naming up to 50 characters (from 24)

+    - 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

+
+  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
+      restarted.
+
+  The the big question:
+    * Does a minimized queue/corpus improve finding new coverage or does it
+      hinder it?
+
+  The AFL++ team's own limited analysis seem to to show that keeping
+  intermediate paths help to find more coverage, at least for afl-fuzz.
+
+  For honggfuzz in comparison it is a good idea to restart it from time to
+  time if you have other fuzzers (e.g: AFL++) running in parallel to sync

+ * t1ha = { Fast Positive Hash, aka "Позитивный Хэш" }
+ * by [Positive Technologies](https://www.ptsecurity.ru)
+ *
+ * Briefly, it is a 64-bit Hash Function:
+ *  1. Created for 64-bit little-endian platforms, in predominantly for x86_64,
+ *     but portable and without penalties it can run on any 64-bit CPU.
+ *  2. In most cases up to 15% faster than City64, xxHash, mum-hash, metro-hash
+ *     and all others portable hash-functions (which do not use specific
+ *     hardware tricks).
+ *  3. Not suitable for cryptography.
+ *
+ * The Future will (be) Positive. Всё будет хорошо.
+ *
+ * ACKNOWLEDGEMENT:
+ * The t1ha was originally developed by Leonid Yuriev (Леонид Юрьев)
+ * for The 1Hippeus project - zerocopy messaging in the spirit of Sparta!

+/*****************************************************************************
+ *
+ * PLEASE PAY ATTENTION TO THE FOLLOWING NOTES
+ * about macros definitions which controls t1ha behaviour and/or performance.
+ *
+ *
+ * 1) T1HA_SYS_UNALIGNED_ACCESS = Defines the system/platform/CPU/architecture
+ *                                abilities for unaligned data access.
+ *
+ *    By default, when the T1HA_SYS_UNALIGNED_ACCESS not defined,
+ *    it will defined on the basis hardcoded knowledge about of capabilities
+ *    of most common CPU architectures. But you could override this
+ *    default behavior when build t1ha library itself:
+ *
+ *      // To disable unaligned access at all.
+ *      #define T1HA_SYS_UNALIGNED_ACCESS 0
+ *
+ *      // To enable unaligned access, but indicate that it significantly slow.
+ *      #define T1HA_SYS_UNALIGNED_ACCESS 1
+ *
+ *      // To enable unaligned access, and indicate that it effecient.
+ *      #define T1HA_SYS_UNALIGNED_ACCESS 2
+ *
+ *
+ * 2) T1HA_USE_FAST_ONESHOT_READ = Controls the data reads at the end of buffer.
+ *
+ *    When defined to non-zero, t1ha will use 'one shot' method for reading
+ *    up to 8 bytes at the end of data. In this case just the one 64-bit read
+ *    will be performed even when the available less than 8 bytes.
+ *
+ *    This is little bit faster that switching by length of data tail.
+ *    Unfortunately this will triggering a false-positive alarms from Valgrind,
+ *    AddressSanitizer and other similar tool.
+ *
+ *    By default, t1ha defines it to 1, but you could override this
+ *    default behavior when build t1ha library itself:
+ *
+ *      // For little bit faster and small code.
+ *      #define T1HA_USE_FAST_ONESHOT_READ 1
+ *
+ *      // For calmness if doubt.
+ *      #define T1HA_USE_FAST_ONESHOT_READ 0
+ *
+ *
+ * 3) T1HA0_RUNTIME_SELECT = Controls choice fastest function in runtime.
+ *
+ *    t1ha library offers the t1ha0() function as the fastest for current CPU.
+ *    But actual CPU's features/capabilities and may be significantly different,
+ *    especially on x86 platform. Therefore, internally, t1ha0() may require
+ *    dynamic dispatching for choice best implementation.
+ *
+ *    By default, t1ha enables such runtime choice and (may be) corresponding
+ *    indirect calls if it reasonable, but you could override this default
+ *    behavior when build t1ha library itself:
+ *
+ *      // To enable runtime choice of fastest implementation.
+ *      #define T1HA0_RUNTIME_SELECT 1
+ *
+ *      // To disable runtime choice of fastest implementation.
+ *      #define T1HA0_RUNTIME_SELECT 0
+ *
+ *    When T1HA0_RUNTIME_SELECT is nonzero the t1ha0_resolve() function could
+ *    be used to get actual t1ha0() implementation address at runtime. This is
+ *    useful for two cases:
+ *      - calling by local pointer-to-function usually is little
+ *        bit faster (less overhead) than via a PLT thru the DSO boundary.
+ *      - GNU Indirect functions (see below) don't supported by environment
+ *        and calling by t1ha0_funcptr is not available and/or expensive.
+ *
+ * 4) T1HA_USE_INDIRECT_FUNCTIONS = Controls usage of GNU Indirect functions.
+ *
+ *    In continue of T1HA0_RUNTIME_SELECT the T1HA_USE_INDIRECT_FUNCTIONS
+ *    controls usage of ELF indirect functions feature. In general, when
+ *    available, this reduces overhead of indirect function's calls though
+ *    a DSO-bundary (https://sourceware.org/glibc/wiki/GNU_IFUNC).
+ *
+ *    By default, t1ha engage GNU Indirect functions when it available
+ *    and useful, but you could override this default behavior when build
+ *    t1ha library itself:
+ *
+ *      // To enable use of GNU ELF Indirect functions.
+ *      #define T1HA_USE_INDIRECT_FUNCTIONS 1
+ *
+ *      // To disable use of GNU ELF Indirect functions. This may be useful
+ *      // if the actual toolchain or the system's loader don't support ones.
+ *      #define T1HA_USE_INDIRECT_FUNCTIONS 0
+ *
+ * 5) T1HA0_AESNI_AVAILABLE = Controls AES-NI detection and dispatching on x86.
+ *
+ *    In continue of T1HA0_RUNTIME_SELECT the T1HA0_AESNI_AVAILABLE controls
+ *    detection and usage of AES-NI CPU's feature. On the other hand, this
+ *    requires compiling parts of t1ha library with certain properly options,
+ *    and could be difficult or inconvenient in some cases.
+ *
+ *    By default, t1ha engade AES-NI for t1ha0() on the x86 platform, but
+ *    you could override this default behavior when build t1ha library itself:
+ *
+ *      // To disable detection and usage of AES-NI instructions for t1ha0().
+ *      // This may be useful when you unable to build t1ha library properly
+ *      // or known that AES-NI will be unavailable at the deploy.
+ *      #define T1HA0_AESNI_AVAILABLE 0
+ *
+ *      // To force detection and usage of AES-NI instructions for t1ha0(),
+ *      // but I don't known reasons to anybody would need this.
+ *      #define T1HA0_AESNI_AVAILABLE 1
+ *
+ * 6) T1HA0_DISABLED, T1HA1_DISABLED, T1HA2_DISABLED = Controls availability of
+ *    t1ha functions.
+ *
+ *    In some cases could be useful to import/use only few of t1ha functions
+ *    or just the one. So, this definitions allows disable corresponding parts
+ *    of t1ha library.
+ *
+ *      // To disable t1ha0(), t1ha0_32le(), t1ha0_32be() and all AES-NI.
+ *      #define T1HA0_DISABLED
+ *
+ *      // To disable t1ha1_le() and t1ha1_be().
+ *      #define T1HA1_DISABLED
+ *
+ *      // To disable t1ha2_atonce(), t1ha2_atonce128() and so on.
+ *      #define T1HA2_DISABLED

+ *   1. The quality of hash is a subject for tradeoffs with performance.

+# 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 :-)

+## 6) Persistent record, and replay
+
+If your software under test requires keeping a state between persistent loop iterations (i.e., a stateful network stack), you can use the `AFL_PERSISTENT_RECORD` variable as described in the [environment variables documentation](../docs/env_variables.md).
+
+When `AFL_PERSISTENT_RECORD` is enabled, replay functionality is also included in the compiler-rt library. To replay a specific record, assign the record number to the AFL_PERSISTENT_REPLAY environment variable (i.e., `RECORD:XXXXX`` -> `AFL_PERSISTENT_REPLAY=XXXXX`), and run the test binary as you would normally do.
+The directory where the record files live can be specified via the `AFL_PERSISTENT_DIR` environment varilable, otherwise by default it will be considered the current directory (`./`).
+
+If your harness reads the input files from arguments using the special `@@` argument you will need to include support by enabling `AFL_PERSISTENT_ARGPARSE` in  `config.h`.
+
+In order to offer transparent support to harnesses using the `@@` command line argument, arguments are parsed by the `__afl_record_replay_init` init function. Since not all systems support passing arguments to initializers, this functionality is disabled by default, it's recommendable to use the `__AFL_FUZZ_TESTCASE_BUF/__AFL_FUZZ_TESTCASE_LEN` shared memory mechanism instead.
+
+## 7) Drop-in persistent loop replay replacement
+
+To use the replay functionality without having to use `afl-cc`, include the [include/record_compat.h](../include/afl-record_compat.h) header file. Together with the [include/afl-persistent-replay.h](../include/afl-persistent-replay.h) header included in it, `afl-record-compat.h` provides a drop-in replacement for the persistent loop mechanism.
+
+```c
+#ifndef __AFL_FUZZ_TESTCASE_LEN
+  // #define AFL_PERSISTENT_REPLAY_ARGPARSE
+  #include "afl-record-compat.h"
+#endif
+
+__AFL_FUZZ_INIT();
+```
+
+A simple example is provided in [persistent_demo_replay.c](../utils/replay_record/persistent_demo_replay.c).
+
+Be aware that the [afl-record-compat.h](../include/afl-record-compat.h) header should only be included in a single compilation unit, or you will end up with clobbered functions and variables.
+
+If you need a cleaner solution, you'll have to move the functions and variables defined in [include/record_compat.h](../include/afl-record-compat.h) and [include/afl-persistent-replay.h](../include/afl-persistent-replay.h) in a C file, and add the relevant declarations to a header file. After including the new header file, the compilation unit resulting from compiling the C file can then be linked with your program.
