Today I've checked that it really works as I read from the source code. I use this tool to read events: https://gist.github.com/avagin/430ba431fc2972002df40ebe6a048b36 And I see that events from non-network devices are delivered to all sockets, but events from network devices are delivered only to sockets from a network namespace where a device is operated.
