Description
Kernel Live Patching allows fixing kernel bugs without rebooting
or stopping the workload. It is an essential tool to keep modern
data centers health with fast evolving kernels and workloads.
The Live Patching MC at Linux Plumbers 2026 aims to gather
stakeholders and interested parties to discuss proposed features
and outstanding issues in live patching.
Possible topics for this year:
- Test framework for livepatch subsystem and the new klp-build
toolchain - Live Patch compatibility with tracing solutions (kprobe, ftrace,
BPF trampoline, etc.) - Split a live patch module into submodules
- SFrame and livepatch
- Hybrid live patch idea
- Use AI to help build live patch
Work landed based on previous versions of the Live Patching MC:
- Live patching for arm64
- Live patching for Loongarch64
- Live patching for LTO (with klp-build tool chain)
