Yes, I would like to extend objref infra later once this is accepted. > This might also allow you to refer to this new object type from > nf_tables maps. Yes, but first nft needs to be able to construct some meaningful output again. If we don't attach a specific label (such as filename), we need to be able to reconstruct info based on what we can query via id/tag and bpf syscall. objref infra doesn't help here unless we'll force something like 'nft-defined-objref-name-must-match-elf-binary-name', and I find that terrible. > It would be good to avoid linear rule-based matching to select what > program to run. Hmmm, I did not consider it a huge deal, its an ebpf program so users can dispatch to another program. Objref is nice if the program to run should be selected from a criterion that isn't readily available to a sk_filter program though.
