Dear Members, I'm sorry to write here, but http://bugs.wireshark.org seems to be down.
I have a PCAP file which contains a fragmented 802.11 A-MSDU. At the last frame where reassembly happens, Wireshark tells me: Malformed Packet (Exception occured). After analyzing the issue carefully, I came to the conclusion that there might be a bug in Wireshark. The reason being is that if I change the simulator to write the MSDU subframe header length field in little endian byte order, then the packet validation error goes away. In this case, I can see all MSDUs properly in the reassembled A-MSDU. Unfortunately, at the same time a new error appears due to incorrect MSDU length during dissecting. I think the error is caused by the fact that the packet validator assumes little endian byte order, while the dissecting code *correctly* assumes big endian byte order as required by the standard. I found this to be related to the following bug report: https://www.wireshark.org/lists/wireshark-bugs/201302/msg00166.html I am using Wireshark 2.0.2. Could somebody give me some hints whether I'm right or wrong? Best regards, Levente Meszaros
