Sockets representing the TCP endpoints for iWARP connections are allocated by the ibcore module. Before this revision they were closed either by the ibcore module or the iw_cxgbe hardware driver depending on the state transitions during connection teardown. This is error prone and there were cases where both iw_cxgbe and ibcore closed the socket leading to double-free panics. The fix is to let ibcore close the sockets it creates and never do it in the driver. - Use sodisconnect instead of soclose (preceded by solinger = 0) in the driver to tear down an RDMA connection abruptly. This does what's intended without releasing the socket's fd reference. - Close the socket in ibcore when the iWARP iw_cm_id is destroyed. This works for all kinds of sockets: clients that initiate connections, listeners, and sockets accepted off of listeners.
