How to use add_packet_field in a Wireshark Lua dissector?

QUESTION

How to use add_packet_field in a Wireshark Lua dissector?

Asked 2020-Jul-08 at 21:49

I am stumbling my way through writing a dissector for our custom protocol in Lua. While I have basic field extraction working, many of our fields have scale factors associated with them. I'd like to present the scaled value in addition to the raw extracted value.

It seems to me tree_item:add_packet_field is tailor-made for this purpose. Except I can't get it to work.

I found Mika's blog incredibly helpful, and followed his pattern for breaking my dissector into different files, etc. That's all working.

Given a packet type "my_packet", I have a 14-bit signed integer "AOA" that I can extract just fine

...

Looking at the try_add_packet_field() source code, only certain FT_ types are supported, namely:

FT_BYTES
FT_UINT_BYTES
FT_OID
FT_REL_OID
FT_SYSTEM_ID
FT_ABSOLUTE_TIME
FT_RELATIVE_TIME

None of the other FT_ types are supported [yet], including FT_UINT16, which is the one you're interested in here, i.e., anything else just needs to be done the old fashioned way.

If you'd like this to be implemented, I'd suggest filing a Wireshark enhancement bug request for this over at the Wireshark Bug Tracker.
