+# Test ip:::{send,receive} of IPv4 UDP 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 message using ping and checks that at least the
+# following counts were traced:
+#
+# 1 x ip:::send (UDP sent to ping's base UDP port)
+# 1 x udp:::send (UDP sent to ping's base UDP port)
+# 1 x ip:::receive (UDP received)
+#
+# No udp:::receive event is expected as the response ping -U elicits is
+# an ICMP PORT_UNREACHABLE response rather than a UDP packet, and locally
+# the echo request UDP packet only reaches IP, so the udp:::receive probe
+# is not triggered by it.
+#
+
+if (( $# != 1 )); then
