Subject: wireshark decoding of nfsv4.1

Bruce,

I stumbled upon a bug in wireshark decoding of NFSv4.1 open res
when delegation_type==OPEN_DELEGATE_NONE_EXT where od_whynone
seems to be ignored.

Who owns that code nowadays?

There seems to be a bug in pynfs in this area as well
which I'm trying to debug.

Benny

Apparently the bug was in my server xdr encoding code.
I just submitted a patch to fix that.

I don't know, I see a lot of 4.1 problems, and I don't know if it's the
wireshark version in my distro or if the problems are in upstream. I
haven't had time to fool with it in a few years.

That doesn't sound familiar to me.
