Linux Kernel Debugging: Going Beyond Printk Messages
Knowing how to debug the Linux kernel is an essential skill for every embedded Linux developer. And debugging the Linux kernel with printk messages is a common technique (often a good one). The problem happens when we only know this debugging technique. How to debug a kernel oops message? How to trace and understand the kernel execution? How to identify and analyze a buffer overflow? How to identify a memory leak or a deadlock in kernel space? In many situations, there are more effective kernel debugging tools and techniques, including KGDB, ftrace, addr2line, eBPF, kmemleak, and so on. In this presentation, we will go over these and many other very useful tools to identify and fix problems in the Linux kernel.
