ib_ucm_cleanup_events() holds file_mutex while calling ib_destroy_cm_id(). This can deadlock since ib_destroy_cm_id() flushes event handlers, and ib_ucm_event_handler() needs file_mutex, too. Therefore, drop the file_mutex during the call to ib_destroy_cm_id(). Signed-off-by: NMichael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: NRoland Dreier <rolandd@cisco.com>

The ib_cm_establish() function is replaced with a more generic ib_cm_notify(). This routine is used to notify the CM that failover has occurred, so that future CM messages (LAP, DREQ) reach the remote CM. (Currently, we continue to use the original path) This bumps the userspace CM ABI. New alternate path information is captured when a LAP message is sent or received. This allows QP attributes to be initialized for the user when a new path is loaded after failover occurs.

Modifications to the existing rdma header files, core files, drivers, and ulp files to support iWARP, including: - Hook iWARP CM into the build system and use it in rdma_cm. - Convert enum ib_node_type to enum rdma_node_type, which includes the possibility of RDMA_NODE_RNIC, and update everything for this.

The P_Key is provided into a SIDR REQ in two places, once as a parameter, and again in the path record. Remove the P_Key as a parameter and always use the one given in the path record. This change has no practical effect on ABI functionality. Signed-off-by: NSean Hefty <sean.hefty@intel.com> Signed-off-by: NRoland Dreier <rolandd@cisco.com>

Fix race condition during destruction calls to avoid possibility of accessing object after it has been freed. Instead of waking up a wait queue directly, which is susceptible to a race where the object is freed between the reference count going to 0 and the wake_up(), use a completion to wait in the function doing the freeing.

Current IB code doesn't work with userspace programs that listen only to the kernel event netlink socket as it is trying to create its own dev interface. This small patch fixes this problem, and removes some unneeded code as the driver core handles this logic for you automatically.

- Add user specified context to all uCM events. Users will not retrieve any events associated with the context after destroying the corresponding cm_id. - Provide the ib_cm_init_qp_attr() call to userspace clients of the CM. This call may be used to set QP attributes properly before modifying the QP. - Fixes some error handling synchonization and cleanup issues. - Performs some minor code cleanup.
