From 6e67e586e7289c144d5a189d6e0fa7141d025746 Mon Sep 17 00:00:00 2001 From: Hans Schillstrom Date: Mon, 3 Jan 2011 14:44:57 +0100 Subject: IPVS: netns, connection hash got net as param. Connection hash table is now name space aware. i.e. net ptr >> 8 is xor:ed to the hash, and this is the first param to be compared. The net struct is 0xa40 in size ( a little bit smaller for 32 bit arch:s) and cache-line aligned, so a ptr >> 5 might be a more clever solution ? All lookups where net is compared uses net_eq() which returns 1 when netns is disabled, and the compiler seems to do something clever in that case. ip_vs_conn_fill_param() have *net as first param now. Three new inlines added to keep conn struct smaller when names space is disabled. - ip_vs_conn_net() - ip_vs_conn_net_set() - ip_vs_conn_net_eq() *v3 moved net compare to the end in "fast path" Signed-off-by: Hans Schillstrom Acked-by: Julian Anastasov Signed-off-by: Simon Horman --- net/netfilter/ipvs/ip_vs_proto_tcp.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'net/netfilter/ipvs/ip_vs_proto_tcp.c') diff --git a/net/netfilter/ipvs/ip_vs_proto_tcp.c b/net/netfilter/ipvs/ip_vs_proto_tcp.c index 757aaaf083bb..d8b3f9f15826 100644 --- a/net/netfilter/ipvs/ip_vs_proto_tcp.c +++ b/net/netfilter/ipvs/ip_vs_proto_tcp.c @@ -620,7 +620,7 @@ tcp_unregister_app(struct net *net, struct ip_vs_app *inc) static int tcp_app_conn_bind(struct ip_vs_conn *cp) { - struct netns_ipvs *ipvs = net_ipvs(&init_net); + struct netns_ipvs *ipvs = net_ipvs(ip_vs_conn_net(cp)); int hash; struct ip_vs_app *inc; int result = 0; -- cgit v1.2.3
