-Subject: [PATCH] ide: ahci: reset ncq object to unused on error
-
-When processing NCQ commands, AHCI device emulation prepares a
-NCQ transfer object; To which an aio control block(aiocb) object
-is assigned in 'execute_ncq_command'. In case, when the NCQ
-command is invalid, the 'aiocb' object is not assigned, and NCQ
-transfer object is left as 'used'. This leads to a use after
-free kind of error in 'bdrv_aio_cancel_async' via 'ahci_reset_port'.
-Reset NCQ transfer object to 'unused' to avoid it.

-From: Prasad J Pandit <address@hidden>
-
-When IDE AHCI emulation uses Frame Information Structures(FIS)
-engine for data transfer, the mapped FIS buffer address is stored
-in a static 'bounce.buffer'. When a request is made to map another
-memory region, address_space_map() returns NULL because
-'bounce.buffer' is in_use. It leads to a null pointer dereference
-error while doing 'dma_memory_unmap'. Add a check to avoid it.
