Lock debugging within the kernel

As we’ve learned, locking and synchronization design and implementation can tend to become complex, thus increasing the chances of lurking bugs. The kernel has several means to help debug these difficult situations regarding kernel-level locking issues, deadlock being a primary one.

Just in case you haven’t already, do ensure you’ve first read the basics on synchronization, locking, and deadlock guidelines from the previous chapter (Chapter 12, Kernel Synchronization – Part 1, especially the Critical sections, exclusive execution, and atomicity and Concurrency concerns within the Linux kernel sections).

With any debug scenario, there are different points at which debugging occurs, and thus, perhaps differing tools and techniques that could/should be used.

Kaiwan N. Billimoria

Kaiwan N. Billimoria taught himself BASIC programming on his dad's IBM PC back in 1983. He was programming in C and Assembly on DOS until he discovered the joys of Unix, and by around 1997, Linux! Kaiwan has worked on many aspects of the Linux system programming stack, including Bash scripting, system programming in C, kernel internals, device drivers, and embedded Linux work. He has actively worked on several commercial/FOSS projects. His contributions include drivers to the mainline Linux OS and many smaller projects hosted on GitHub. His Linux passion feeds well into his passion for teaching these topics to engineers, which he has done for well over two decades now. He's also the author of Hands-On System Programming with Linux, Linux Kernel Programming (and its Part 2 book) and Linux Kernel Debugging. It doesn't hurt that he is a recreational ultrarunner too.
