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.
