This passing the "struct ip_vs_iphdr" actually makes sense. It reminds me of the way netfilter/iptables passes the xt_actions_param to each rule. Which contains the same information as ip_vs_iphdr. (note ipvs register at hooks at a lower level and don't get passed the xt_actions_param). Thus, perhaps we should keep these API changes. Even if we decide to optimize ipv6_find_hdr(). (as proposed by my RFC patch) Perhaps we should consider adding a "family" to ip_vs_iphdr, as is done in xt_actions_param. This could help us, with collapsing IPv4 and IPv6 code, but i can see that other structs in IPVS carry this info already, so not sure its relevant. -- 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
