- 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

- Add a function that dissects a sequence of TLV's instead of having
while() loops all over the place.

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.

1. Fix dissection of Check Point vendor ID version field. The length was
wrong.
2. Added dissection of payloads 130 and 131, which were used in early
NAT-T drafts (and are still used by MS and others). They are equal to
payloads 15 & 16, (NAT-D, NAT-OA), respectively.
3. Added ASN.1 decoding of Certificate requests of type X.509
Certificate - Signature (4)
4. Added ASN.1 decoding of ID of type ID_DER_ASN1_DN (9)

within the file) and "burst offset" field (offset of this packet within
the burst).
The burst header is not present if the SYS flag is set in the packet or
if the data offset field is non-zero.
Compute the offset, within a burst packet, of the data, as we advance
through the burst header - and don't advance through the burst header if
it's not present.
Properly display the fields in the "missing fragment list".

make the dissectors "new-style" dissectors and return 0 for packets that
don't look like iSNS. Do this *before* doing TCP reassembly - once
you've done reassembly, it's too late.
Don't set the columns in the main dissector routines - it's also done in
the PDU dissector, which is sufficient. Set the protocol column to
"iSNS", not "isns".

I've written this patch to use the 'Delay since last SR' (DLSR) field found
in SR reports to calculate and report roundtrip-propagation delays. This is
described in rfc 3550, section 6.4.1, inside the description of DLSR.
Only the endpoint can compute the end-end roundtrip delay, and only they
know exactly when the report is received and can compare it with the 'Last
SR timestamp' (LSR) that they set. This patch instead takes the difference
between the capture times of the 2 reports and subtracts the DLSR (the LSR
is checked in case the SR it's referring to wasn't captured). The time
difference represents a roundtrip network delay between the point of capture
and the sender of the SR containing the DLSR.

1. As you said visible fileds are much better.
2. As they became visible I noticed the length and offset of the fields
were wrong, I fixed them.
3. I added few more "essential" fields (as a colleague told me as soon
as you move away from 3G some fileds like username become the most
important)

so that IF kerberos succeeds in decrypting a blob it can print a nice
"[Decrypted using: keytab principal foo/bar@REALM]"
or
"[Decrypted using: key learnt from frame xx]"
This makes it much easier to keep track of what keys decrypt what blob
and is very useful for illustrating the sequence of keys that are exchanged and used in kerberos during the AS/TGS/AP exchanges.

ethereal used to (bug) print in the summary line

make ethereal attempt to automatically detect wether header digest is used or not for iscsi sessions.
This makes ethereal decode the packets properly EVEN for perfectly normal sessions where
the discovery session is performed with no digest but the normal login session negotiates digest.
the detected headerdigest setting is tcp session wide and thus it
it does not work for such initiators (if such exist) that resuse the same socketpair between the discovery and normal login sessions.

If window scaling is NOT offered in the SYN+ACK then window scaling will
not be used at all, so clear it if we saw it offered previously in the SYN packet.
If the window is scaled in a packet, make ethereal display that by appendign the

decode pane.

references to a packet - just re-"decrypt" it (not a lot of work, given
the sophisticated encryption MAPI uses). We don't save decrypted data
for non-trivial encryptions, so there's not much of a reason to save it
here - and the code to save it was at least sometimes not finding it
again, causing crashes.
Set the length and reported length of the decrypted data tvbuff
appropriately.

I (hopefully) didn't changed any protocol fields or preference file names, but only the GUI labels appearing in the protocol display and the protocol preferences.
Also added a note to the protocol preferences (where appropriate), that you have to enable "Allow subdissectors to reassemble TCP streams" at the corresponding protocol settings for TCP reassembling to take effect.
If you encounter any mistakes I've made here, please let me know...

It also says there's some other stuff, such as a client MAC address,

come right after the database offset/length, there's an offset/length
for the NTLMSSP message). Put in a comment about that.

1. define new TDS packet type (17) - NTLM authentication packet. Call
the ntlmssp dissector to dissect it when needed.
2. define new TDS packet type (18) - donno what it is exactly, but it's

3. heuristic in netlib_check_login_pkt should also check port 2433.
4. unify the dissection of msg and err token. They have the same
structure.
