Hi all,
I'm developing an extension for the GTPv1 dissector and while I was debugging
I've encountered something that it seems to me a bit confusing. In the
dissect_gtp_common function from the packet-gtp.c source, there is a section
that makes the matching between requests and responses. The thing is that I
have a pcap in which I have a create PDP context request with sequence number
equal to 0, then when in the code asks if the message has sequence number, it
never enters in that part because, I guess, that 0 is equal than NULL.
If (seq_no) {
/* matching is done */
}
I don't know If this is a little bug or maybe the sequence number can't be
equal to 0. Can someone help me?
Thanks!
Regards.
