C Sample

This shows a simple persistent harness for unicornafl in C. In contrast to the normal c harness, this harness manually resets the unicorn state on each new input. Thanks to this, we can rerun the testcase in unicorn multiple times, without the need to fork again.

Compiling sample.c

The target can be built using the make command. Just make sure you have built unicorn support first:

cd /path/to/afl/unicorn_mode
./build_unicorn_support.sh

Compiling persistent_target.c

You don't need to compile persistent_target.c since a X86_64 binary version is pre-built and shipped in this sample folder. This file documents how the binary was built in case you want to rebuild it or recompile it for any reason.

The pre-built binary (persistent_target_x86_64.bin) was built using -g -O0 in gcc.

We then load the binary and we execute the main function directly.
