# custum mutator: libfuzzer LLVMFuzzerMutate()
|
|
|
|
This uses the libfuzzer LLVMFuzzerMutate() function in llvm 12.
|
|
|
|
just type `make` to build
|
|
|
|
```AFL_CUSTOM_MUTATOR_LIBRARY=custom_mutators/libfuzzer/libfuzzer-mutator.so afl-fuzz ...```
|
|
|
|
Note that is is currently simple and is missing two features:
|
|
* Splicing ("Crossover")
|
|
* Dictionary support
|
|
|
|
To update the source, all that is needed is that FuzzerDriver.cpp has to receive
|
|
```
|
|
#include "libfuzzer.inc"
|
|
```
|
|
before the closing namespace bracket.
|
|
|
|
It is also libfuzzer.inc where the configuration of the libfuzzer mutations
|
|
are done.
