Hi, I guess I found another bug: | # nft 'table ip t { chain c { ip saddr { }; }; }' | Error: syntax error, unexpected '}' | table ip t { chain c { ip saddr { }; }; } | ^ Now, this does match what the documentation says (you have to have at least one item in a set literal), but I would think that that also should count as a bug, as (a) it isn't exactly useful to have arbitrary exceptions on what (set) values can be specified and (b) nftables handles empty sets just fine, it's just the input syntax that is complicated.
