network interfaces. This global mutex will protect all ifnet labels. Acquire the mutex across various MAC activities on interfaces, such as security checks, propagating interface labels to mbufs generated from the interface, retrieving and setting the interface label. Introduce mpo_copy_ifnet_label MAC policy entry point to copy the value of an interface label from one label to another. Use this to avoid performing a label externalize while holding mac_ifnet_mtx; copy the label to a temporary ifnet label and then externalize that. Implement mpo_copy_ifnet_label for various MAC policies that implement interface labeling using generic label copying routines.
