Did we already document that? > I remember we discussed it, can you share a link to that discussion? Yes, it silently tries outer scopes. The previous discussion is here: https://patchwork.kernel.org/project/netdevbpf/patch/20231130214959.27377-7-donald.hunter@xxxxxxxxx/#25622101 This is the doc patch that describes sub-messages: https://patchwork.kernel.org/project/netdevbpf/patch/20231215093720.18774-4-donald.hunter@xxxxxxxxx/ It doesn't mention searching outer scopes so I can add that to the docs.
