Hi,
Is there any reason why the preference to let sub dissectors do TCP reasembly shouldn't be default on ?
As this seems to be a very common "misstake" to make.
Best regards
Anders

It's an issue for *all* TCP dissectors that do reassembly, even if they
don't use "tcp_dissect_pdus()".
It might also belong as a FAQ, as users not writing dissectors also run
across it.

You can't. If the user turns that option off, reassembly won't be done
- which is as it should be. The error shouldn't be "Short Frame"; that
happens on some occasions, not all of which are, I think, associated
with TCP reassembly. Part of the problem might, I think, be due to
requiring multiple lengths for tvbuffs, such as "size the packet would
have been had it been reassembled".

Given that reassembly isn't being done, that would be a bug.
