[Linux-cluster] packet dissectors for totemnet and totemsrp of corosync

[Masatake YAMATO]

I've written wireshark packet dissectors for totemnet and 
totemsrp of corosync.

See the attached png file.

I have already submitted the patch to wireshark developers.

  https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=3232

Currently you have to get the patch from the bugziila and apply it to
the original source code by yourself. I hope the patch is merged in
soon.

The greatest point is this patch supports decryption: you don't have
to turn off "secauth" before capturing. However, "key" is needed to
decrypt the packet.  If you don't specified explicitly in
cluster.conf, the name of cluster is the key. See the bugziila entry
how to give the key to wireshark.

I'm working on upper layer protocols like totempg, cman, "a", clvmd,
and so on.

Enjoy!
