I'm getting this here: libxt_mark.c:116:1: warning: ‘mark_mt_xlate_print’ defined but not used [-Wunused-function] mark_mt_xlate_print(const struct xt_entry_match *match, ^ libxt_mark.c:140:1: warning: ‘mark_xlate_print’ defined but not used [-Wunused-function] mark_xlate_print(const struct xt_entry_match *match, ^ These two functions are unused, so there is some problem there. But, anyway after applying you patch I can see: # iptables-translate -I INPUT -m mark --mark 10 nft insert rule ip filter INPUT ct mark & xa counter So this kind of work already. Be careful about shared libraries for extensions (here I have them at /usr/lib/xtables/*.so or maybe you have it at /usr/local/lib/xtables) The thing is that probably you have an older iptables installation, so you iptables-translate binary refers to the old .so file which has no translation. So make sure you don't have several .so in your setup, probably that's the problem. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
