Project Description

klp-convert is a tool that is trying to be merged into the Linux Kernel to help livepatching non exported functions. Since kallsymsoneachsymbol and kallsymslookup_name were unexported, klp-convert appeared to solve the issue by creating relocation entries for non-export functions in the final livepatch module.

This will help the kernel livepatching team to improve our tooling by not relying in the kallsyms functions anymore.

Goal for this Hackweek

Read and understand klp-convert Comment the patches and help it to get a new iteration of the patchset, and in the future help the feature to be merged
