auditing labeled ipsec

Linux provides two apis to add/delete/manage SAs and spd. One is netlink which was extended to do key management. The other is pfkeyv2, which our setkey and racoon uses. With all that said, I am not able to figure out how to get "auid" from pfkeyv2? I can use NETLINK_CB(skb).loginuid to get it when netlink is used, but I don't think I can use this for pfkeyv2 since I am not using netlink headers. I am using pfkey message headers, such as sadb_msg, which don't include this. Any ideas or suggestions? Regards, Joy
