OK, thanks very much to you and James for all the explanation. And
actually the IB specs do appear to be available if you give them your
name and address?
So could one of you add some of this (the explanation of the security
issues, at least) to Documentation/filesystems/nfs-rdma.txt?
I'm worried about the fact that the amount of trust required in the
network will vary so much depending on exactly which hardware and kernel
version the user has.
As long as this is relatively specialized hardware, perhaps it's not
such a big deal.... But at the very least I think we should make sure
this is carefully documented.
ok. will do.
