Finding kernel race bugs through fuzzing


$ source scripts/envsetup.sh

scripts/envsetup.sh sets up necessary environment variables. One should select the kernel version during environment setup, for example, v4.17.

Initialize kernels_repo submodule

Kernel source codes used in this project are in the other reprository which is included as a submodule. To initialize the submodule one should execute git submodule update command as a follow.

$ git submodule update --init --depth=1 kernels_repo

Dependencies

$ sudo apt install zlib libglib-dev python-setuptools quilt libssl-dev dwarfdump

Install toolchains / tools

$ scripts/install.sh

scripts/install.sh then installs all the rest necessary toolchains and tools.

The Razzer’s static analysis is based on the LLVM toolchain and the SVF static analysis tool. See documents in docs/static-analysis.md.

Razzer’s two-phases fuzzing is based on Syzkaller. The deterministic scheduler is implemented using QEMU/KVM. See documents in docs/fuzzing.md.
