Ariel Nahum 504130c039 IB/iser: Protect iser state machine with a mutex ... The iser connection state lookups and transitions are not fully protected. Some transitions are protected with a spinlock, and in some cases the state is accessed unprotected due to specific assumptions of the flow. Introduce a new mutex to protect the connection state access. We use a mutex since we need to also include a scheduling operations executed under the state lock. Each state transition/condition and its corresponding action will be protected with the state mutex. The rdma_cm events handler acquires the mutex when handling connection events. Since iser connection state can transition to DOWN concurrently during connection establishment, we bailout from addr/route resolution events when the state is not PENDING. This addresses a scenario where ep_poll retries expire during CMA connection establishment. In this case ep_disconnect is invoked while CMA events keep coming (address/route resolution, connected, etc...).
