I was asking on how to properly do reassembly before I started, but did not get much more that references to tcp_dissect_pdus().
tcp_dissect_pdus() is useful *ONLY* for protocols that: run immediately atop TCP; have, for each PDU, a section at the beginning, guaranteed to be at least N bytes long for some value of N, and from which the length of the PDU can be determined; and is only useful for reassembling pieces of TCP segments into a PDU for those protocols. There are a *lot* of protocols like that, so it's very useful... ...but it's not the only mechanism for doing reassembly, and it shouldn't be suggested to people trying to do other forms of reassembly - for example, protocols running over something other than TCP, or having their own level of fragmentation over and above fragmentation into pieces of TCP segments. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
