Catch kernel memory defects with KASAN, UBSAN, SLUB debug, and kmemleak.Use static and dynamic Kprobes to trap into kernel/module functions.Explore instrumentation-based printk along with the powerful dynamic debug framework.This book covers the following exciting features: You’ll also discover how to handle kernel lockups, hangs, and the dreaded kernel panic, as well as leverage the venerable GDB tool within the kernel (KGDB), along with much more. Some thorny issues, both debug- and performance-wise, require detailed kernel-level tracing you’ll learn to wield the impressive power of Ftrace and its frontends. ![]() Concurrency tends to be an inherently complex topic, so a chapter on lock debugging will help you to learn precisely what data races are, including using KCSAN to detect them. When the kernel gifts you an Oops, how exactly do you interpret it to be able to debug the underlying issue? We’ve got you covered. Memory-related bugs tend to be a nightmare – two chapters are packed with tools and techniques devoted to debugging them. This book covers many areas in depth, such as instrumentation-based debugging techniques (printk and the dynamic debug framework), and shows you how to use Kprobes. Linux Kernel Debugging is a comprehensive guide to learning all about advanced kernel debugging. Leverage proven tools and advanced techniques to effectively debug Linux kernels and kernel modules What is this book about? This is the code repository for Linux Kernel Debugging, published by Packt.
