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.
