pbr: custom proto tunnels can't be used

Package Name

pbr

Maintainer

Stan Grishin

OpenWrt Version

24.10.2

OpenWrt Target/Subtarget

ramips/mt7621

Steps to Reproduce

1. Add interface with custom tunneling proto, e.g. amneziawg (from other sources)
2. Execute ubus -S call luci.pbr getInterfaces command.
3. Observe that there is no added amneziawg interface in the list of supported interface for PBR

Actual Behaviour

/etc/init.d/pbr contains some code to determine the supported interfaces types. This method is hardcoded and doesn't allow to add custom protocol types.

It would be cool if script contains some sort of hook which can be used to install additional criteria by other packages providing custom tunneling protos.

Confirmation Checklist

• The package is maintained in this repository.
• I understand that issues related to the base OpenWrt repository or LuCI repository will be closed.
• I am reporting an issue for OpenWrt, not an unsupported fork.

Start with /etc/init.d/pbr and the interface detection used by ubus -S call luci.pbr getInterfaces. Trace how supported interface types are determined, then define a hook that other packages can use to register custom tunneling protocols. Done means an added amneziawg interface appears in the supported interface list.
