It's OK: notification of new interfaces comes via netlink, so it gets synchronised via the select() call just like everything else. Have I mentioned yet that Simon is a hero? :-) New code is in git (and I released 2.63test1) change --bind-interfaces to --bind-dynamic as see how it goes. > > Do we have to worry about races outside of dnsmasq?

Because it's using netlink rather than polling, the delay is pretty short (I know that's not a solution to races, but it does help.)
