Description

syzkaller is an open-source coverage-guided OS kernel fuzzer used to continuously test the Linux kernel. To date syzkaller has found 3000+ bugs in the upstream kernel. The kernel sanitizers are a family of dynamic bug finding tools (KASAN, KMSAN, KCSAN) that detect various types of bugs in the kernel.
In this talk Dmitry will give an overview of new developments in the past year for syzkaller and sanitizers and share some stats for kernel bugs and syzkaller contributions. Then Dmitry will outline the testing process of the syzkaller itself and some nice features that the kernel testing process could borrow. The talk concludes with future work for syzkaller/sanitizers.
