How can I get notifications in my kext of network interfaces attaching and detaching? I'm specifically interesting in utun interfaces, which aren't picked up by listening on IONetworkInterface matching notifications. It seems I should be able to listen on the associated kernel event, but I don't see any examples of doing that from kernel space.

I believe you can do that in the kernel using a kernel event socket. You'll need to use the socket kpis to create the in-kernel kernel event socket to listen for notifications (sock_socket, etc... from sys/kpi_socket.h). See: http://developer.apple.com/library/mac/#documentation/Darwin/Reference/Kerne...

I'm not aware of a good example.

I'm just guessing, but doesn't 'scutil' provide notifications (so might have an example of how to code such)? Its code is available. Justin -- Justin C.
