Ubuntu Summit 2022 Day 3 (09 November 2022)
Let's meet the kernel livepatch feature by Marek Maślanka
A kernel livepatch is a powerful feature that allows to patch of a kernel at the runtime. Thanks to kernel livepatch, millions of servers over the world can work continuously without reboots.
In this presentation, I will discuss how the kernel livepatching works under the hood. What are the limitations of the livepatch and what hurdles lurk when preparing a livepatch.
I will also show how to prepare from scratch a simple and advanced livepatch module. How to deal with when a livepatch must get access to non-exported functions of the kernel.
