Some questions:
1. Can you provide (or point me to) a capture file (or files) containing the
GSM_CELL_BROADCAST protocol which would exercise the various code paths
code in dissect_gsm_cell_broadcast() ?
It would be helpful if the capture contained a single "page" as well as
multiple pages (which would need to be concatenated (defragmented).
Also: can you provide a capture file with data encoded as SMS_ENCODING_UCS2
?
2. In dissect_cbs_data():
The 'SMS_ENCODING_7BIT' case returns a UTF8 tvb (after unpacking, etc)
The 'SMS_ENCODING_UCS2' case uses iconv to convert to UTF8 but then
discards the converted buffer.
Is there some reason why the UTF8 buffer isn't returned in this case
in a manner similar to that for the SMS_ENCODING_7BIT case ?
3. While testing with the attached capture file I noticed that
the list of 'protocols in the frame' (shown in the details pane) did not
include 'gsm_cell_broadcast'.
After a little poking around I found that this is because
dissect_sabp_Broadcast_Message_Content() in packet-sabp.c calls
dissect_umts_cell_broadcast_message() directly thus bypassing the
Wireshark code which keeps track of the protocols in a frame.
I'm guessing that this case should also be treated as a 'protocol'....
(in a manner similar to that used to call dissect_gsm_cell_broadcast() ?)
Thanks
Bill
