From: Julian Anastasov <ja@xxxxxx> commit fc604767613b6d2036cdc35b660bc39451040a47 ("ipvs: changes for local real server") from 2.6.37 introduced DNAT support to local real server but the IPv6 LOCAL_OUT handler ip_vs_local_reply6() is registered incorrectly as IPv4 hook causing any outgoing IPv4 traffic to be dropped depending on the IP header values. Chris tracked down the problem to CONFIG_IP_VS_IPV6=y Bug report: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1349768 Reported-by: Chris J Arges <chris.j.arges@xxxxxxxxxxxxx> Tested-by: Chris J Arges <chris.j.arges@xxxxxxxxxxxxx> Signed-off-by: Julian Anastasov <ja@xxxxxx> Signed-off-by: Simon Horman <horms@xxxxxxxxxxxx> --- net/netfilter/ipvs/ip_vs_core.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/net/netfilter/ipvs/ip_vs_core.c b/net/netfilter/ipvs/ip_vs_core.c index e683675..5c34e8d 100644 --- a/net/netfilter/ipvs/ip_vs_core.c +++ b/net/netfilter/ipvs/ip_vs_core.c @@ -1906,7 +1906,7 @@ static struct nf_hook_ops ip_vs_ops[] __read_mostly = { { .hook = ip_vs_local_reply6, .owner = THIS_MODULE, - .pf = NFPROTO_IPV4, + .pf = NFPROTO_IPV6, .hooknum = NF_INET_LOCAL_OUT, .priority = NF_IP6_PRI_NAT_DST + 1, }, -- 1.7.10.4 -- 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
