Description
We want to discuss live patching with clang built LTO kernel. We have managed to make it work on top of kpatch now. We would like to discuss:
How current comparison with vmlinux binary itself not scalable.
How we used clang lto internal flag to compare pre-linker object files.
How new special symbols introduced by lto may complicate live patching and how build system needs to adapt from it.
Whether and how we can improve kpatch to support comparison with vmlinux itself.
