I noticed a similar issue in ipath_iba6110.c around line 599.
Do you want me to correct or do you want to catch it with a single patch?

Intercept socket calls and convert TCP socket operation to
streaming over RDMA.
Allow falling back from rsockets to normal sockets on error
or when trying to bind/connect to a reserved port. This is
needed to handle MPI job startup, where MPI should use rsockets,
but mpiexect needs to communicate
rstream provides an example that uses either rsocket or socket
APIs. The latter allows rstream to be used to verify rsocket
behavior compared to socket.

The following patch set contains an initial implementation of rsockets as
presented at the 2012 OpenFabrics Workshop. A copy of that presentation
is available at:

and a video of the presentation can be found here:
rcopy will copy files from a source system to a specified remote
server. It's essentially a really dumb FTP type program that can
be used to quickly transfer files between systems, which can be
useful to verify data integrity.
(It was easier to create this program than modify an existing FTP

It looks like the call to ib_create_srq() is failing.
What specific HCA type do you have? Do you have up-to-date firmware?
I thought all mthca hardware is SRQ-capable,

If, in ib_link_query_port(), the call to mlx4_MAD_IFC() fails we will
currently do 'return err;' which will leak 'in_mad' and 'out_mad' that
we previously allocated. I believe we should instead do 'goto out;'
where we'll properly free the memory we previously allocated.

I did look at aio and other interfaces, but I didn't try to move beyond the
