For pin maps, we only set the pin path and let libbp load to handle it. For tail calls, we find it first and update the element ... WebCilium uses iproute2 loader, also has ELF parsing in golang Goal: everything out of native golang, only debugging generated object files via iproute2/bpftool Both would have same behavior Bindings would be under upstream under tools/lib/bpf/ Challenge: keeping up with libbpf pace, binding test coverage
