Hello,
I am working on two plugins : the first for Lnet and the second for
Lustre 1.6.5.1 (www.lustre.org). Just to be clear, this mail is not a
submission
request (for now).
The stack of Lustre and Lnet is :
----------
| LUSTRE |
----------
| LNET |
----------
| TCP |
----------
Other native network types are supported by LNET, like Infiniband (OFED),
Quadrics (Elan3, Elan4) or Myricom, etc. However, this plugin is for TCP
only.
It is my first wireshark-plugin, and I think that I have done some
mistakes, so
could you please read the code and tell me if I'm going wrong.
I have questions(problems) too :
1 ) About flow graph : I use dissector_add(..) to add lustre above Lnet,
but I
get some problem when I try to use flow graph :
The flow graph still shows only Lnet information (no Lustre info), and I
have a
similar problem when I switch to black and white after being in color
mode : I lost
Lustre information (however, a refresh works in this case).
2 ) About conversation : I like the key CTRL-1, CTRL-2... To color tcp
conversation, how can I do that with Lnet conversation.
Lnet uses a field to identify a conversation : a 64 bits field :
match_bits , so
I wrote a function : get_Lnet_conv() to find a tcp_conversation and add
the different information about this Lnet conversation in a hash table
(like
packet-afs.c), but I can't find to get something similar to tcp color
conversation.
I have check the code in packet-jxta.c too, but I didn't find what I want.
3 ) About flags, I didn't find a good way to process the flag field (64
bytes flag
field), so I made a loop to add all flags and use TFS() per flag.
Is there a better way to process flags ?
Thanks in advance.
