Ok I can add the netlink_xfrm_socket stuff to upstream.  They will be in 
tonights policy

The unlabeled_t should be gone with the latest policy.

I am not sure about

allow ifconfig_t unconfined_t:udp_socket { read write };
allow ifconfig_t initrc_t:udp_socket { read write };
allow ifconfig_t initrc_t:unix_stream_socket { read write };
allow traceroute_t initrc_t:rawip_socket { read write };
allow traceroute_t initrc_t:udp_socket { read write };
allow traceroute_t user_home_dir_t:dir search;

Could you attach avc messages for these?
