From 3eaf9f532021326a47f70046b05854d8b1819825 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Fri, 15 Jul 2022 15:21:40 +1000 Subject: tests: Correct determination of host interface name in tests By default, passt itself attaches to the first host interface with a default route. However, when determining the host interface name the tests implicitly select the *last* host interface: they use a jq expression which will list all interfaces with default routes, but the way output detection works in the scripts, it will only pick up the last line. If there are multiple interfaces with default routes on the host, and they each have a different address, this can cause spurious test failures.
