"In general strings are not NULL terminated and are encoded using UTF8."
It also says
Authentication
Over the years, the AIM backend has supported several different
methods for authentication. ...
When a client collects the loginId and password for the user it
should not normalize them in any manner. It also should not
prevent the user from entering certain characters as the AIM
name space is constantly changing. For example, currently the
AIM name space is ASCII based, but in the future that may
change. In general, the client should not perform input
checking and instead allow the backend to reject bad values.
which also suggests not assuming ASCII.
So use ENC_UTF_8 in most cases.
For actual messages, it says:
An IM can be encoded in the following different forms:
Name Value Notes
ASCII 0 ANSI ASCII -- ISO 646
UNICODE 2 ISO 10646.USC-2 Unicode
LATIN_1 3 ISO 8859-1
so, if that's the case, the dissector should choose beween
ENC_ASCII|ENC_NA, ENC_UCS_2|ENC_appropriate_ENDIAN, and
ENC_ISO_8859_1|ENC_NA.
Use tvb_get_string_enc() with an encoding rather than tvb_get_string().

FT_IPXNET
FT_OID
Note: Encoding field set to ENC_NA only if the field was previously TRUE|FALSE|ENC_LITTLE_ENDIAN|ENC_BIG_ENDIAN

Improved AIM protocol dissector:
* Decodes more values acording to official Oscar spec
* Renamed clientautoresp to client_err (as written in spec)
* Fix decoding orror on rendezvous channel
* Other small improvements
svn path=/trunk/; revision=29953
(1) Trailing/leading spaces are removed from 'name's/'blurb's
(2) Duplicate 'blurb's are replaced with NULL
(3) Empty ("") 'blurb's are replaced with NULL
(4) BASE_NONE, NULL, 0x0 are used for 'display', 'strings' and 'bitmask' fields
for FT_NONE, FT_BYTES, FT_IPv4, FT_IPv6, FT_ABSOLUTE_TIME, FT_RELATIVE_TIME,
FT_PROTOCOL, FT_STRING and FT_STRINGZ field types
(5) Only allow non-zero value for 'display' if 'bitmask' is non-zero

The dissect_aim_tlv_value_extended_data function does not work for iChat
generated rendezvous data. So I switched back to the generic value display.
Added another Rendezvous TLV name.

I've extended the AIM dissector with the information available from http://dev.aol.com/aim/oscar .
I've verified most of the additions by sniffing my iChat (OSX 10.4) data traffic.
svn path=/trunk/; revision=26813
most have been tagged unused (few have been deleted if dissector has not been
modified since a long time)
move packet-ssl-utils.c to DISSECTOR_SRC

A patch to the AIM dissector to support Client Auto Response messages. I still don't know the meaning of all the fields as they weren't all mapped but this patch decodes all the important ones.

as the description - some aim_tlv tables have NULL in the end-of-table
entry.
For those that don't, replace "Unknown" with NULL; "Unknown" is now
redundant.

- Dissect ICQ TLV values
- Dissect channel 1 and channel 2 messages correctly in Oscar (required
for dissecting direct connections)
svn path=/trunk/; revision=12072
- Dissect the DC (Direct Connection) info structure
- Dissect the complete buddy icon family (you can now save buddy
icons as .JPG's/.PNG's directly from the capture using the "Export
selected bytes..." option!)
- Add a function that dissects a sequence of TLV's instead of having
while() loops all over the place.
svn path=/trunk/; revision=12063
Remove some code duplication from the Oscar dissector (reduces
the number of lines by 500) by providing a custom registration
function for oscar families (aim_init_family). This also fixes
a number of issues with column names.
Add minor updates such as adding support for the Capability Info
TLV on users.
svn path=/trunk/; revision=12060
Also move ncp222.py, x11-fields, process-x11-fields.pl,
make-reg-dotc, and make-reg-dotc.py.
Adjust #include lines in files that include packet-*.h
files.
