After a second thought, I'll self-NACK this one: Given that netlink API is completely unrelated to ioctl one, there is no inherent need to do things the same way. Looking at RTM_NEWLINK handler, it seems possible to create interface names containing a colon via netlink. Of course those interfaces are not accessible via ioctl() then, but so are secondary interface addresses which don't have a properly chosen label. Sorry for the noise, Phil
