# Test {ip,udplite}:::{send,receive} of IPv4 UDP-Lite to a local address.
#
# This may fail due to:
#
# 1. A change to the ip stack breaking expected probe behavior,
# which is the reason we are testing.
# 2. No physical network interface is plumbed and up.
# 3. No other hosts on this subnet are reachable and listening on rpcbind.
# 4. An unlikely race causes the unlocked global send/receive
# variables to be corrupted.
#
# This test sends a UDP-Lite message using perl and checks that at least the
# following counts were traced:
#
# 1 x ip:::send (UDPLite sent to UDP-Lite port 33434)
# 1 x udplite:::send (UDPLite sent to UDP-Lite port 33434)
# 1 x ip:::receive (UDP-Lite received)
# 1 x udplite:::receive (UDP-Lite received)
#
# A udplite:::receive event is expected even if the received UDP-Lite packet
# elicits an ICMP PORT_UNREACHABLE message since there is no UDP-Lite
# socket for receiving the packet.
#
if (( $# != 1 )); then
print -u2 "expected one argument: <dtrace-path>"
