the following: It is now possible to enable/disable a particular protocol decoding (i.e. the protocol dissector is void or not). When a protocol is disabled, it is displayed as Data and of course, all linked sub-protocols are disabled as well. Disabling a protocol could be interesting: - in case of buggy dissectors - in case of wrong heuristics - for performance reasons - to decode the data as another protocol (TODO) Currently (if I am not wrong), all dissectors but NFS can be disabled (and dissectors that do not register protocols :-) I do not like the way the RPC sub-dissectors are disabled (in the sub-dissectors) since this could be done in the RPC dissector itself, knowing the sub-protocol hfinfo entry (this is why, I've not modified the NFS one yet). Two functions are added in proto.c : gboolean proto_is_protocol_enabled(int n); void proto_set_decoding(int n, gboolean enabled); and two MACROs which can be used in dissectors: OLD_CHECK_DISPLAY_AS_DATA(index, pd, offset, fd, tree) CHECK_DISPLAY_AS_DATA(index, tvb, pinfo, tree) See also the XXX in proto_dlg.c and proto.c around the new functions. svn path=/trunk/; revision=2267

/*
|
|
* NOTES
|
|
*
|
|
* This module defines routines to disassemble RSVP packets, as defined in
|
|
* RFC 2205. All objects from RC2205 are supported, in IPv4 and IPv6 mode.
|
|
* In addition, the Integrated Services traffic specification objects
|
|
* defined in RFC2210 are also supported.
|
|
*
|
|
* IPv6 support is not completely tested
|
|
*
|
|
* Mar 3, 2000: Added support for MPLS/TE objects, as defined in
|
|
* <draft-ietf-mpls-rsvp-lsp-tunnel-04.txt>
