I am trying to restrict an application I have installed to have access to a specific network interface only (tun0).
Are all network interfaces labelled 'automatically' by SELinux with 'netif_xx_t' or do I have to label them manually from the policy file? If I have to do that manually is it done with the network_interface(...) macro?
Also, if I relabel the interface would I have to amend all other policies for applications which need access to that interface (applications which use the 'generic' naming - netif_t) or is this not necessary?
I've seen there is a macro in corenetwork.if.in called 'corenet_all_recvfrom_labelled' - is that macro allowing me to receive packets from labelled interface?
Thanks in advance!

I just wanted to note that I have had much more difficulty knowing if I have control over my network devices since the 2.6.30 kernel. Network control (Internet) is the only reason I use SELinux. If there is new and improved documentation for the usage of the network controls, I would greatly appreciate knowing about it.
