From fc723250c9cb046cc19833a2b1c4309bbf59ac36 Mon Sep 17 00:00:00 2001 From: Hans Schillstrom Date: Mon, 3 Jan 2011 14:44:43 +0100 Subject: IPVS: netns to services part 1 Services hash tables got netns ptr a hash arg, While Real Servers (rs) has been moved to ipvs struct. Two new inline functions added to get net ptr from skb. Since ip_vs is called from different contexts there is two places to dig for the net ptr skb->dev or skb->sk this is handled in skb_net() and skb_sknet() Global functions, ip_vs_service_get() ip_vs_lookup_real_service() etc have got struct net *net as first param. If possible get net ptr skb etc, - if not &init_net is used at this early stage of patching. ip_vs_ctl.c procfs not ready for netns yet. *v3 Comments by Julian - __ip_vs_service_find and __ip_vs_svc_fwm_find are fast path, net_eq(svc->net, net) so the check is at the end now. - net = skb_net(skb) in ip_vs_out moved after check for skb_dst.
