Re: [libvirt] [PATCH] dissectors: Create dissector for Libvirt RPC

This patch creates basic dissector for Libvirt RPC. The protocol description can be found here: http://libvirt.org/internals/rpc.html Currently, only packet head dissecting is written. To fully dissect packet payloads a more effort is needed, as each function has different arguments (in general). However, this can be good stepping stone for later expansion. Ideally, a script that will generate this dissector from libvirt RPC file would be written. --- Okay, this patch obviously belongs to wireshark mailing list, but before I'll send it there, I guess we should decide if we want it there. I mean there are 2 modes/ways for wireshark dissectors: 1) Place it into wireshark repo as many others. Advantage: wireshark will be shipped with support for libvirt RPC Disadvantage: wireshark will be shipped with support for libvirt RPC In other words, if you look at wireshark releases, they are not as often as ours, so in the end, this dissector will be always one or more step behind current libvirt. But many users will be able to use it right after box open. 2) Dissector as plugin Advantage: we can update it as often as we want Disadvantage: users needs to install a plugin Personally, I prefer 2) as libvirt RPC is expanded pretty often, and I expect this dissector to be used by libvirt developer mainly, for who installing a plugin into wireshark can't be a real problem :)

The table of string for labeling procedures, has been generated by hand, but I intend to write script for that. Currently, only message header is dissected, no payload. Yeah, script will generate structures for that too.
