From b5ef10cfeb839dca28ae5376bfabafe29ae07aec Mon Sep 17 00:00:00 2001 From: Christian Poessinger Date: Sat, 17 Oct 2020 20:06:36 +0200 Subject: ifconfig: T2985: support on demand bridge creation The current implementation for bridge based interfaces has an issue which is caused by priority inheritance. We always assumed that the bridge interface will be created last, but this may not be true in all cases, where some interfaces will be created "on demand" - e.g. OpenVPN or late (VXLAN, GENEVE). As we already have a bunch of verify steps in place we should not see a bridge interface leak to the underlaying infrastructure code. This means, whenever an interface will be member of a bridge, and the bridge does yet not exist, we will create it in advance in the interface context, as the bridge code will be run in the same commit but maybe sooner or later. This will also be the solution for T2924. --- src/conf_mode/interfaces-tunnel.py | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/conf_mode/interfaces-tunnel.py') diff --git a/src/conf_mode/interfaces-tunnel.py b/src/conf_mode/interfaces-tunnel.py index f1d885b15..5561514bd 100755 --- a/src/conf_mode/interfaces-tunnel.py +++ b/src/conf_mode/interfaces-tunnel.py @@ -462,7 +462,8 @@ def get_config(config=None): options['tunnel'] = {} # check for bridges - options['bridge'] = is_member(config, ifname, 'bridge') + tmp = is_member(config, ifname, 'bridge') + if tmp: options['bridge'] = next(iter(tmp)) options['interfaces'] = interfaces() for name in ct: -- cgit v1.2.3
