I tried to integrate this into nftables, but failed to understand how this all is supposed to come together: In nftables, concat is treated like any other expression. Your series seems to require special treatment? At least there are separate "desc" data structures for each. It seems like one can't just replace build_udata callbacks to populate an nftnl_expr_desc object? Cheers, Phil
