Such change should fix a problem where connection templates don't get full IPv6 address for the real server, only the first 4 bytes are copied and as result it works only for IPv4. > + cp->vport = p->vport; > + ip_vs_addr_set(p->af, &cp->daddr, p->daddr); > cp->dport = dport; > cp->flags = flags; > cp->fwmark = fwmark; > -- > 1.8.1.4 Regards -- Julian Anastasov <ja@ssi.bg> -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Sorry for that, looks like I ran the test build after adapting to current code with a config which didn't actually compile this file. I'll send a v2 after testing a fixed version and I'll also extend the commit message to describe the outcome.
