Ethereal-dev: [Ethereal-dev] [PATCH] decouple dcerpc authentication from packet-dcerpc.c
Note: This archive is from the project's previous web site, ethereal.com. This list is no longer active.
From: Tim Potter <tpot@xxxxxxxxx>
Date: Tue, 15 Jul 2003 15:21:49 +1000
This is something I've been wanting to do for a while. The attached patch
decouples dissection of DCERPC authentication verifiers and payloads from
packet-dcerpc.c by allowing dissector modules to register a table of
handler functions for dissecting the verifiers in bind, bind ack, auth3,
request and response PDUs.
The patch modifies the NTLMSSP dissector to use the new interface. Also
it adds a small bit of extra functionality which I don't think ethereal
supported before - NTLMSSP signing of DCERPC. Previously we only supported
NTLMSSP encryption (sign&seal).
Caveats:
- There are still a few issues to work out with the value_string for the
DCE_C_RPC_AUTHN_PROTOCOL_* constants.
- SPNEGO and secure channel dissections are broken but should be easy to
convert to the new interface.
Again I'm putting this out there for anyone (probably Guy (-:) to comment
on. I'm not 100% happy with the naming of some of the members of the
subdissector_fns structure but that's pretty easy to fix.
Tim.
