We are pleased to announce that the Live Patching Microconference has been accepted into the 2019 Linux Plumbers Conference! There are some workloads that require 100% uptime so rebooting for maintenance is not an option. But this can make the system insecure as new security vulnerabilities may have been discovered in the running kernel. Live kernel patching is a technique to update the kernel without taking down the machine. As one can imagine, patching a running kernel is far from trivial. Although it is being used in production today[1][2], there are still many issues that need to be solved.

These include:

• API for state changes made by callbacks [3][4]
• Source-based livepatch creation tooling [5][6] (klp-convert) [7][8]
• Livepatch developers guide
• Userspace live patching

Come and join us in the discussion about changing your running kernel without having to take it down!

We hope to see you there!
