Hi, Michael,
I still have difficulty in understanding the code, and very painful in
developing the M2UA V2 dissector.
I found the the explanation of the parameter length definition of V2: the value
of length is only for the value. The parameter hdeader(tag and the length) are
*NOT* included. That is why in V2, the length is 4, not 8.
You stated that "Length=8 is coded nowhere".
Here are my concerns:
1. How does Wireshark know the expected value is 8? How does the "Malformed
pakcet" string come up?
2. I want to decode tvb in V2 way, any way to control the offset? In
packet-m3ua.c #1298~#1323, I do not see any offset control. How does Wireshark
which parameter block it is dissecting?
Maybe my questions are stupid, thanks very much. Michael.
