Wireshark · Ethereal-dev: [Ethereal-dev] GIOP Update before release

[Frank Singleton <frank.singleton@xxxxxxxxxxxx>]

Hi,

Just a small update to let you know how things are going
with the GIOP enhancements , and a couple of screen
captures so you can see something real. There have
been some minor changes since this but you get the
idea.

giop.png   - shows IOR decoding
giop3.png  - shows a USER EXCEPTION with 3 members.

I expect to release it in approx 4 weeks.

There is a great deal of the API implemented.
ie: get_CDR_xxx , where xxx is a listed in
chapter 15 of the Corba v2.4.2 Spec.

This covers much (but not all) of

 - primitive data types (including ieee float)
 - some IDL constructed types
 - Encapsulation
 - TypeCodes (eg: tk_float, tk_short etc..)
 - "Any" values.
 - Sequence support

Also handles 

0. Provides get_CDR_XXX API for subdissectors

1. Reading stringified IOR's from
   file to statically associate Repository ID's 
   with Object Keys.

2. Decode IOR's according to IIOP IOR profile.
   eg: like "catior" does
   
3. Allows GIOP subdissectors to register both
   for heuristic and explicit dissection of
   GIOP payload data, via eg: Repository ID's.

4. Monitors REQUEST(resolve) for IOR's to dynamically
   associate Repository ID's with Object Keys. This allows
   us to select the correct sub_dissector, based on object key
   in the packet.

5. More I am sure :-)

I am testing this API against some CORBA traffic. 

This was initially using "omniorb", but now I am writing some 
"test suite" in java to check the API for bugs.


The design base was 0.8.15, but I diffed a recent CVS snapshot
 against the 0.8.15 release and noticed only a small
(few lines) changed.

I will port my code to the to latest CVS release
before final testing.


Also, with the GIOP API stabilizing, I am continuing with
an IDL -> Ethereal Dissector generator . I am not sure that it
will make the release date, but it will follow soon after.
So, hopefully you can take your IDL for some CORBA model
and generate a GIOP subdissector automajically.


Cheers / Frank..
