When dma_alloc_coherent() fails during queue creation, the error\n    path calls the free function with req->ring / rsp->ring still NULL\n    (from kzalloc).  The unconditional dma_free_coherent() with a NULL\n    cpu_addr is undefined behavior and can panic.\n\n 2. The free functions clear req_qid_map / rsp_qid_map under vport_lock,\n    but the create functions protect the same bitmaps with mq_lock.\n    This provides no mutual exclusion.  Additionally, the create error\n    path clears the bit and releases mq_lock before calling the free\n    function, creating a window where another thread can allocate the\n    same que_id and have its ha->req_q_map entry clobbered by the\n    subsequent lockless NULL assignment in the free function.\n\nFix by:\n\n - Guarding dma_free_coherent() with a NULL check on the ring pointer.\n\n - Using mq_lock (the lock held by all creators) in the free functions\n   to atomically NULL the map entry and clear the bitmap bit.\n\n - Removing the now-redundant clear_bit blocks from the create error\n   paths since the free functions handle it atomically."
