Good day to all,
I have been trying to figure out a behavior for a while now where the 'filter name' (third parameter of proto_register_protocol() function) does not filter the captured messages.
For a brief background, I am studying/using an existing openflow dissector:
https://github.com/CPqD/ofdissectorI have scanned the README.developer and from looking at the ofdissector code, everything seems to be in order.
At first I thought that the 'filter name' should be the same as the first 'prefix' of the display filters registered in hf_register_info declarations. Meaning if the display filters are like 'abc.yyy.xxx', the filter name should be 'abc'.
But I think this does not necessarily need to be the case as I tried changing the prefixes in another of my dissectors and the filter name seems to work fine.
Does anyone have any possible leads/reasons/hypothesis as to where should I be looking to fix this?
Thank you in advance.
Best regards,
David
