I am seeing Memory Leaks in ib_rdma_bw application at below places when ran with valgrind tool:
1. Memory allocated by aspintf() is not freed, as it goes on heap, caller should call "free" after done with the string. 2. Memory allocated by remote destination filed (struct pp_data *) is not freed. 3. rdma_create_event_channel() calls ucma_init() but rdma_destroy_event_channel() does not call ucma_cleanup(), this results into memory leak at provider's library since it does not call ibv_close_device() and thus unable to do *->free_context(). 4. Memory allocated for (struct cma_id_private *) at RDMA_CM_EVENT_CONNECT_REQUEST event is not getting freed. It is calling rdma_destroy_id but that was for rdma_create_id. Thus one block of cm_id_private still remains allocated. This accounts to ~533 bytes in each iteration. Am I observing correctly?
