Receipt of CM MAD with other than the Send method for an attribute other than the ClassPortInfo attribute is invalid. CM attributes other than ClassPortInfo only use the send method. The SRP initiator does not maintain a timeout policy for CM connect requests relies on the CM layer to do that. The result was that the SRP initiator hung as the connect request never completed. A new SRP target has been observed to respond to Send CM REQ with GetResp of CM REQ with bad status. This is non conformant with IBA spec but exposes a vulnerability in the current MAD/CM code which will respond to the incoming GetResp of CM REQ as if it was a valid incoming Send of CM REQ rather than tossing this on the floor. It also causes the MAD layer not to retransmit the original REQ even though it has not received a REP.
