I think my biggest concern is we don't inadvertently open a security
hole on a machine that just happens to have an iwarp card installed,
but has nothing to do with HPC.

The clearest scary path I see is a server listening on a QP and using
IB_ACCESS_REMOTE_WRITE. That sure looks easy to exploit.

A client doing this.. It is alot harder to exploit.. iSER is client
only, so less worrying. Can anyone else think of a way to attack the
client?
