From 76ba129151da6c5f910256dba1743b321af04af5 Mon Sep 17 00:00:00 2001 From: Stewart Addison Date: Tue, 14 Jul 2020 14:30:44 +0100 Subject: [PATCH] net: allow wider regex in interface name Zone IDs on Linux are network interface names. The regex we use to determine valid IPs does not allow for non-alphanumeric characters in the zone ID suffix. Some machines (including the RHEL Linux/s390x machines from Marist) have zone IDs with a '.' character in them which the regex in net.isIP rejects. This changes the regex.
