 2.6.32-stable tree

Ok, I was able to reproduce it finally. This fixes it:

---
diff --git a/kernel/sysctl_check.c b/kernel/sysctl_check.c
index b6e7aae..469193c 100644
--- a/kernel/sysctl_check.c
+++ b/kernel/sysctl_check.c
@@ -220,6 +220,7 @@ static const struct trans_ctl_table
trans_net_ipv4_conf_vars_table[] = {
        { NET_IPV4_CONF_PROMOTE_SECONDARIES,    "promote_secondaries" },
        { NET_IPV4_CONF_ARP_ACCEPT,             "arp_accept" },
        { NET_IPV4_CONF_ARP_NOTIFY,             "arp_notify" },
+       { NET_IPV4_CONF_SRC_VMARK,              "src_valid_mark" },
        {}
 };

Note we dont have that code anymore in current tree - thats why it
was missed...
If this works, Greg/Dave - please include it in the -stable patch.

cheers,
jamal
