The first packet in a sequence of TCP packets in a reassembled PDU does not get
its reassembled_in property set.
For a very high-level example, say there were 4 packets in a HTTP response
Frame 4322 [TCP segment of a reassembled PDU]
Frame 4323 [TCP segment of a reassembled PDU]
Frame 4325 [TCP segment of a reassembled PDU]
Frame 4326 HTTP/1.1 200 OK
In this example, the protocol tree for frame 4322 will not contain a link to
frame 4326, while the trees for frames 4323 and 4325 do contain a link. Frame
4322 doesn't match the filter: "tcp.reassembled_in". Frame 4323 and frame 4325
both match the filter.
My understanding of TCP isn't deep enough to see what's causing the issue, so I
haven't submitted a patch. However the issue is reproducible in any capture
containing reassembled TCP (such as HTTP responses).
If you can point me to the right place to fix the problem I'll be happy to
supply a patch.
Cheers
Chris
