By "notification" I assume you mean netlink notification. > > Any tricks or APIs to get around this? The question is why does the process in A still care about the device sitting in B? Also, the process should be able to receive a last notification on IFF_UP|IFF_RUNNING before device is finally moved to B. After this point, it should not have any relation to netns A any more, like the device were completely gone.
