When a TCP segment contains the end of two or more SSL PDUs, the TCP reassembly code passes that segment up to the SSL dissector multiple times--one for each SSL PDU. The SSL dissector queues the packet for SSL tap listeners each time it is invoked. Therefore a single packet can be processed by SSL tap listeners multiple times. But the tap data that the SSL dissector sends to its tap listeners is a linked list of all PDUs in the packet. The SSL tap listener responsible for populating the Follow SSL Stream dialog did not account for the possibility of seeing a packet multiple times. As a result, it would process the entire linked list of PDUs each time it received a packet, and that would result in some SSL PDUs showing up two or more times in the dialog. This patch fixes the described bug. It also implements a few slight improvements in closely related code. See bugzilla for details. svn path=/trunk/; revision=49387
