Send a security protocol command to a device that receives data and/or the result
|
|
of one or more commands sent by SendData.
|
|
|
|
The ReceiveData function sends a security protocol command to the given MediaId.
|
|
The security protocol command sent is defined by SecurityProtocolId and contains
|
|
the security protocol specific data SecurityProtocolSpecificData. The function
|
|
returns the data from the security protocol command in PayloadBuffer.
|
|
|
|
For devices supporting the SCSI command set, the security protocol command is sent
|
|
using the SECURITY PROTOCOL IN command defined in SPC-4.
|
|
|
|
For devices supporting the ATA command set, the security protocol command is sent
|
|
using one of the TRUSTED RECEIVE commands defined in ATA8-ACS if PayloadBufferSize
|
|
is non-zero.
|
|
|
|
If the PayloadBufferSize is zero, the security protocol command is sent using the
|
|
Trusted Non-Data command defined in ATA8-ACS.
|
|
|
|
If PayloadBufferSize is too small to store the available data from the security
|
|
protocol command, the function shall copy PayloadBufferSize bytes into the
|
|
PayloadBuffer and return EFI_WARN_BUFFER_TOO_SMALL.
|
|
|
|
If PayloadBuffer or PayloadTransferSize is NULL and PayloadBufferSize is non-zero,
|
|
the function shall return EFI_INVALID_PARAMETER.
|
|
|
|
If the given MediaId does not support security protocol commands, the function shall
|
|
return EFI_UNSUPPORTED. If there is no media in the device, the function returns
|
|
EFI_NO_MEDIA. If the MediaId is not the ID for the current media in the device,
|
|
the function returns EFI_MEDIA_CHANGED.
|
|
|
|
If the security protocol fails to complete within the Timeout period, the function
|
|
shall return EFI_TIMEOUT.
|
|
|
|
If the security protocol command completes without an error, the function shall
|
|
return EFI_SUCCESS. If the security protocol command completes with an error, the
|
|
function shall return EFI_DEVICE_ERROR.
|
|
|
|
@param This Indicates a pointer to the calling context.
|
|
@param MediaId ID of the medium to receive data from.
|
|
@param Timeout The timeout, in 100ns units, to use for the execution
|
|
of the security protocol command. A Timeout value of 0
|
|
means that this function will wait indefinitely for the
|
|
security protocol command to execute. If Timeout is greater
|
|
than zero, then this function will return EFI_TIMEOUT
|
|
if the time required to execute the receive data command
|
|
is greater than Timeout.
|
|
@param SecurityProtocolId The value of the "Security Protocol" parameter of
|
|
the security protocol command to be sent.
|
|
@param SecurityProtocolSpecificData The value of the "Security Protocol Specific" parameter
|
|
of the security protocol command to be sent.
|
|
@param PayloadBufferSize Size in bytes of the payload data buffer.
|
|
@param PayloadBuffer A pointer to a destination buffer to store the security
|
|
protocol command specific payload data for the security
|
|
protocol command. The caller is responsible for having
|
|
either implicit or explicit ownership of the buffer.
|
|
@param PayloadTransferSize A pointer to a buffer to store the size in bytes of the
|
|
data written to the payload data buffer.
|
|
|
|
@retval EFI_SUCCESS The security protocol command completed successfully.
|
|
@retval EFI_WARN_BUFFER_TOO_SMALL The PayloadBufferSize was too small to store the available
|
|
data from the device. The PayloadBuffer contains the truncated data.
|
|
@retval EFI_UNSUPPORTED The given MediaId does not support security protocol commands.
|
|
@retval EFI_DEVICE_ERROR The security protocol command completed with an error.
|
|
@retval EFI_NO_MEDIA There is no media in the device.
|
|
@retval EFI_MEDIA_CHANGED The MediaId is not for the current media.
|
|
@retval EFI_INVALID_PARAMETER The PayloadBuffer or PayloadTransferSize is NULL and
|
|
PayloadBufferSize is non-zero.
