LUA: How can I read protocol pref tcp.desegment_tcp_streams?

Question

Hi,

I'm adding some code to a LUA Wireshark postdissector script and I need to check if "Allow subdissector to reassemble TCP streams" is enabled in Preferences -> Protocols -> TCP

I have other areas of code where I create and later read preference values for my subdissector protocol, e.g.

transum.prefs.client_side = Pref.bool( "Client side trace", true, "Uncheck this if the trace was captured adjacent to the service" )
.
.
if transum.prefs.client_side and retran and stream_dir[s] == 0 then

This all works fine. I just can't figure out how to read compiled dissector preferences.

How can I read tcp.desegment_tcp_streams?

Thanks and regards...Paul

Answer 1

There does not appear to be a way to read another dissector's preference from Lua.

But why do you want to? No other dissector reads this preference.

If you really want it, you could always submit an enhancement request (with a use case).
