These are example and helper files for the custom mutator feature. See docs/custom_mutators.md for more information
Note that if you compile with python3.7 you must use python3 scripts, and if you use python2.7 to compile python2 scripts!
simple_example.c - most simplest example. generates a random sized buffer filled with ‘A’
example.c - this is a simple example written in C and should be compiled to a shared library. Use make to compile it and produce libexamplemutator.so
example.py - this is the template you can use, the functions are there but they are empty
post_library_gif.so.c - fix a fuzz input to ensure it is valid for GIF
post_library_png.so.c - fix a fuzz input to ensure it is valid for PNG
simple-chunk-replace.py - this is a simple example where chunks are replaced
common.py - this can be used for common functions and helpers. the examples do not use this though. But you can :)
wrapper_afl_min.py - mutation of XML documents, loads XmlMutatorMin.py
XmlMutatorMin.py - module for XML mutation
custom_mutator_helpers.h is an header that defines some helper routines like surgical_havoc_mutate() that allow to perform a randomly chosen mutation from a subset of the havoc mutations. If you do so, you have to specify -I /path/to/AFLplusplus/include when compiling.
