In Episode 41, Hacking the Linux Kernel, Part 2, I successfully hacked the Linux kernel, both on a native Linux partition, and within a Ubuntu VM on VirtualBox, by using the general directions within the Linux Newbies First Kernel Patch tutorial. This week, I worked towards hacking the Linux kernel using a Yocto-based qemux86 on VirtualBox, as a final step towards actually hacking the kernel on my MinnowBoard.

It’s been a few months since I did any work with my MinnowBoard; time seems to fly by during the summer. In this episode, I pick up where I left off, doing various Yocto builds as I worked towards source-level debug of the Linux kernel. But, I’m having mysterious build failures, with some of the segmentation fault symptoms I had months ago before I RMA’ed my AMD CPU. Could this be raising its ugly head again?

System Management Mode (SMM) is an x86 operating mode in which all normal execution, including the operating system, is suspended. SMM is of interest to cybersecurity specialists (black hat and white hat) because it can also be abused to run high-privileged rootkits. This week, I decided to use SourcePoint to explore some of its mysteries.
