RETURN_STATUS EFIAPI RestoreAllLockBoxInPlace | ( | VOID | ) |
This function will restore confidential information from all lockbox which have RestoreInPlace attribute.
RETURN_SUCCESS | the information is restored successfully. | |
RETURN_NOT_STARTED | it is too early to invoke this interface | |
RETURN_UNSUPPORTED | the service is not supported by implementaion. |
RETURN_STATUS EFIAPI RestoreLockBox | ( | IN GUID * | Guid, | |
IN VOID * | Buffer, | |||
IN OUT UINTN * | Length | |||
) |
This function will restore confidential information from lockbox.
Guid | the guid to identify the confidential information | |
Buffer | the address of the restored confidential information NULL means restored to original address, Length MUST be NULL at same time. | |
Length | the length of the restored confidential information |
RETURN_SUCCESS | the information is restored successfully. | |
RETURN_INVALID_PARAMETER | the Guid is NULL, or one of Buffer and Length is NULL. | |
RETURN_WRITE_PROTECTED | Buffer and Length are NULL, but the LockBox has no LOCK_BOX_ATTRIBUTE_RESTORE_IN_PLACE attribute. | |
RETURN_BUFFER_TOO_SMALL | the Length is too small to hold the confidential information. | |
RETURN_NOT_FOUND | the requested GUID not found. | |
RETURN_NOT_STARTED | it is too early to invoke this interface | |
RETURN_ACCESS_DENIED | not allow to restore to the address | |
RETURN_UNSUPPORTED | the service is not supported by implementaion. |
RETURN_STATUS EFIAPI SaveLockBox | ( | IN GUID * | Guid, | |
IN VOID * | Buffer, | |||
IN UINTN | Length | |||
) |
This function will save confidential information to lockbox.
Guid | the guid to identify the confidential information | |
Buffer | the address of the confidential information | |
Length | the length of the confidential information |
RETURN_SUCCESS | the information is saved successfully. | |
RETURN_INVALID_PARAMETER | the Guid is NULL, or Buffer is NULL, or Length is 0 | |
RETURN_ALREADY_STARTED | the requested GUID already exist. | |
RETURN_OUT_OF_RESOURCES | no enough resource to save the information. | |
RETURN_ACCESS_DENIED | it is too late to invoke this interface | |
RETURN_NOT_STARTED | it is too early to invoke this interface | |
RETURN_UNSUPPORTED | the service is not supported by implementaion. |
RETURN_STATUS EFIAPI SetLockBoxAttributes | ( | IN GUID * | Guid, | |
IN UINT64 | Attributes | |||
) |
This function will set lockbox attributes.
Guid | the guid to identify the confidential information | |
Attributes | the attributes of the lockbox |
RETURN_SUCCESS | the information is saved successfully. | |
RETURN_INVALID_PARAMETER | attributes is invalid. | |
RETURN_NOT_FOUND | the requested GUID not found. | |
RETURN_ACCESS_DENIED | it is too late to invoke this interface | |
RETURN_NOT_STARTED | it is too early to invoke this interface | |
RETURN_UNSUPPORTED | the service is not supported by implementaion. |
RETURN_STATUS EFIAPI UpdateLockBox | ( | IN GUID * | Guid, | |
IN UINTN | Offset, | |||
IN VOID * | Buffer, | |||
IN UINTN | Length | |||
) |
This function will update confidential information to lockbox.
Guid | the guid to identify the original confidential information | |
Offset | the offset of the original confidential information | |
Buffer | the address of the updated confidential information | |
Length | the length of the updated confidential information |
RETURN_SUCCESS | the information is saved successfully. | |
RETURN_INVALID_PARAMETER | the Guid is NULL, or Buffer is NULL, or Length is 0. | |
RETURN_NOT_FOUND | the requested GUID not found. | |
RETURN_BUFFER_TOO_SMALL | the original buffer to too small to hold new information. | |
RETURN_ACCESS_DENIED | it is too late to invoke this interface | |
RETURN_NOT_STARTED | it is too early to invoke this interface | |
