Chapter 6: Debugging Kernel Memory Issues – Part 2

Welcome to the second portion of our detailed discussions on a really key topic – understanding and learning how to detect kernel memory corruption defects. In the preceding chapter, we introduced the reason why memory bugs are common and challenging and went on to cover some really important tools and technologies to help catch and defeat them – KASAN and UBSAN (along the way, covering the usage of the newer Clang compiler).

In this chapter, we continue this discussion. Here, we will focus on the following main topics:

Detecting slab memory corruption via SLUB debug
Finding memory leakage issues with kmemleak
Catching memory defects in the kernel – comparison and notes (Part 2)

Kaiwan N. Billimoria

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.
