I implemented libbpf relocation patching support for new classes of instructions and tested against kernel selftests and runqslower program. All of those pass. Thanks a lot, this is going to improve BPF CO-RE experience immensely!

hm... size is useful, actually. Ok, let me play with it, it's hard to get a good idea of BTF from LLVM tests. Verifier will definitely reject such variables, though, so we'll need to do sanitization for sure.
if there is no type information available for extern variables, there is little benefit in having them as DATASEC+VAR. No size, no type. We can get the same information from ELF itself without having to teach verifier and libbpf how to handle these new types. Let's drop this for now? The only potential benefit is having a section name associated with extern, but we can either add that later, or even add it in a way that will require no verifier changes - BTF.ext.
