Recently (Nov) we added logic that protects against a peer negotiating a timestamp, and then not including a timestamp. This involved in the input path doing a goto done_with_input label. Now I suspect the code was cribbed from one in Rack that has to do with the SYN. This had a bug, i.e. it should have a m_freem(m) before going to the label (bbr had this missing m_freem() but rack did not). This then caused the missing m_freem to show up in both BBR and Rack. Also looking at the code referencing m->m_pkthdr.lro_nsegs later (after processing) is not a good idea, even though its only for logging. Best to copy that off before any frees can take place.
