tests: Use ping timeout instead of deadline.
Browse files Browse the repository at this point in the history 
Many system tests currently use ping with the combination of a
low packet count (-c 3), short interval between sends (-i 0.3)
and a _deadline_ of 2 seconds (-d 2).

This combination of options may lead to a situation where more
than count packets are sent however ping will stop when count
packets are received. This results in a failed test due to how
the result is checked, for example:

    ping6 -q -c 3 -i 0.3 -w 2 fc00::3 | FORMAT_PING
    @@ -1,2 +1,2 @@
    -3 packets transmitted, 3 received, 0% packet loss, time 0ms
    +4 packets transmitted, 3 received, 25% packet loss, time 0ms

To reiterate, in the above example there is no packet loss, but
ping stops after _receiving_ 3 packets, not bothering with
waiting for the response to the fourth packet it just sent out.

If we look at the iputils ping manual for the -w deadline option
we can read that this is expected behavior:

 > Specify a timeout, in seconds, before ping exits regardless of
 > how many packets have been sent or received. In this case ping
 > does not stop after count packet are sent, it waits either for
 > deadline expire or until count probes are answered or for some
 > error notification from network.

To avoid these kinds of failures in checks where a response is
expected, we replace ping -w with ping -W.

We keep ping -w for checks where it is expected to NOT get a
response.
