28 # Test {ip,udp}:::{send,receive} of IPv4 UDP to a local address.
30 # This may fail due to:
32 # 1. A change to the ip stack breaking expected probe behavior,
33 # which is the reason we are testing.
34 # 2. No physical network interface is plumbed and up.
35 # 3. No other hosts on this subnet are reachable and listening on rpcbind.
36 # 4. An unlikely race causes the unlocked global send/receive
37 # variables to be corrupted.
39 # This test sends a UDP message using perl and checks that at least the
40 # following counts were traced:
42 # 1 x ip:::send (UDP sent to UDP port 33434)
43 # 1 x udp:::send (UDP sent to UDP port 33434)
44 # 1 x ip:::receive (UDP received)
45 # 1 x udp:::receive (UDP received)
47 # A udp:::receive event is expected even if the received UDP packet
48 # elicits an ICMP PORT_UNREACHABLE message since there is no UDP
49 # socket for receiving the packet.
