Hi, Pavel:

these are failing tests:
	zdtm/transition/socket-tcp, zdtm/transition/socket-tcp6, zdtm/static/socket-tcp6-local, zdtm/static/socket_udplite
	zdtm/static/socket-tcpbuf6, zdtm/static/socket-tcpbuf are failing for the same reason:
		"Can't connect inet socket back: Network is unreachable"

	zdtm/static/packet_sock
		"Error (sockets.c:371): Can't set 263:18 (len 4): Invalid argument" while calling setsockopt() in restore

	zdtm/static/socket-tcp
		"socket-tcp.c:190: can't write (errno = 104 (Connection reset by peer))"

	zdtm/static/socket_udp
		"FAIL: socket_udp.c:96: Can't recv C (errno = 11 (Resource temporarily unavailable))"

Socket is missing in the new network namespace, and connections break, these failings seem reasonable.

maybe we can exclude all socket-tcp*, socket_udp* and packet_sock tests, does that make sense?

Thanks
