Can you try this simple patch and see if it fixes your problem? You will
need to call rdma_accept() or rdma_reject() after receiving a CONNECT_RESPONSE
event. The conn_param to rdma_accept() should be NULL.

Would not cma_rep_recv be required to modify the QP?
Anyway, I'll try.
Hmm, it seems that QP will get modified to RTS on RTU only.
That's bad - I want to move it to RTS on REP, since receive completion
might cross RTU and I want to be able to respond to each send immediately.
No, looking in the code shows that qp will be changed to rtr and then
rts ***before*** sending the RTU since you will call rdma_accept which
in turn will call cma_rep_recv
Or.
