Documentation/Use of new protobuf dissector

In the release notes for 2.6.0 it indicates a new dissector has been added to wireshark for protobuf.

https://www.wireshark.org/docs/relnot...

However, there is no mention of it in either the user or developer documentation.

I have a couple questions:

  1. How to provide the .proto file?
  2. It looks like it doesn't detect fields that contain other fields, and only detects the top level fields. Am I using it wrong?

Thanks.

I would also really like to be able to have a preference where I could e.g. map from UDP port -> .proto file (where presumably the last/root Message type from the file is what would be used). The last comment from last month here https://bugs.wireshark.org/bugzilla/s... gives me hope that Huang Qiangxiong will put up something for review soon.

The 2 issues appear to be related - I don't think you can reliably dissect into embedded messages without knowing the types from the .proto files.

From the source code:

TODO
  Support custom preference settings for embedded messages.
  Dissect message according to '*.proto' files.
