Subject: server rdma todo's

I've got a few very small server-rdma todo's lying around; would you be
the right person to help with them?

- Documentation on nfsrdma security issues. (Examples of setup
that would be secure, under what asssumptions, etc.)
- Fix Kconfig rmda help to mention server too.

What document would this be for? Is there an example of the format for
TCP or UDP?

When do you need this by? We should involve Tom Talpey in this, but he
is away on vacation this week. I think Tucker is on vacation this week
too.

Tucker or I could do that. Which Kconfig did you want to update?

I also need to incorporate Chuck's suggestions into the updated
NFS/RDMA readme.

I'd put in in Documentation/filesystems/ somewhere, maybe with the rdma
howto?

No. I assume (possibly I'm naive) that we all have some idea what the
security model is for tcp and udp. Rdma seems to be very different,
hence worth some explanation.

A more general "linux nfs security issues" document might be a good
thing to do some day....

It's not urgent.

I was just thinking of the SUNRPC_XPRT_RDMA help text.

OK! The latest version I have is what's in the for-2.6.27 branch:

git://linux-nfs.org/~bfields/linux.git for-2.6.27
