How are you going to white-list network-interface names? On Linux at least you can name them almost anything you want: % sudo ip link set eth3 down % sudo ip link set eth3 name "'deal-with-it'" % sudo ip link show "'deal-with-it'" 5: 'deal-with-it': <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 10000 link/ether xx:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff The only interface-name restrictions iproute2 sets is that they can't contain NUL, slash, or white space, and they can't be longer than 15 characters.
