But in a new network namespace these ioctl fail because it is disabled for a namespace different from the init_net_ns. These two lines should not be there as af_inet and af_packet are namespace aware since a long time now. I suppose we forget to remove these lines because we sent the af_packet first, before af_inet was supported. Signed-off-by: Daniel Lezcano Reported-by: Stephane Riviere Signed-off-by: David S.
