Brief Introduction

This project is for BUAA CST SS lab4.

Toolchain

tool	version
Linux	22.04.1-Ubuntu x86_64 GNU/Linux (ensure Unix-like!)
Clang/Clang++	Ubuntu clang version 12.0.1-19ubuntu3 (not 14!)
llvm-config	12.0.1 (not 14.0.0!)
make	GNU Make 4.3 x86_64
cmake	cmake version 3.22.1 (ensure >= 3.10)

Quickstart

1. Run:

   $ ./run.sh
   

2. Then:

   $ bin/fuzz_main                  // default using example/test.cpp for demo.
   

3. For more clarity:

   $ bin/fuzz_main | grep Parent
   $ bin/fuzz_main | grep Child
   $ cat /tmp/.fuzzlab/logs/test.cpp.elf.log | grep testing
   $ cat /tmp/.fuzzlab/logs/test.cpp.elf.log | grep round
   ...
   

4. For more types of bugs (null-deref, doublefree, divby0, uaf, outofboundary):

   $ ./run.sh 1-nullptr.cpp         // for example, nullptr dereference.
   $ bin/fuzz_main 1-nullptr.cpp.elf
   $ cat /tmp/.fuzzlab/logs/1-nullptr.cpp.elf.log
   $ cat /tmp/.fuzzlab/logs/1-nullptr.cpp.elf.log | grep testing
   $ cat /tmp/.fuzzlab/logs/1-nullptr.cpp.elf.log | grep round
