From 205c8c071e8550b2ddd57cfaa71af7345cfd5fe7 Mon Sep 17 00:00:00 2001 From: Paul Holzinger Date: Tue, 31 May 2022 16:49:40 +0200 Subject: fix podman container restore without CreateNetNS When a container does not use the default podman netns, for example --network none or --network ns:/path a restore would fail because the specgen check validates that c.config.StaticMAC is nil but the unmarshaller sets it to an empty slice. While we could make the check use len() > 0 I feel like it is more common to check with != nil for ip and mac addresses. Adding omitempty tag makes the json marshal/unmarshal work correctly. This should not cause any issues.
