/**
|
|
The function is used to do the authentication for FMP capsule based upon
|
|
EFI_FIRMWARE_IMAGE_AUTHENTICATION.
|
|
|
|
The FMP capsule image should start with EFI_FIRMWARE_IMAGE_AUTHENTICATION,
|
|
followed by the payload.
|
|
|
|
If the return status is RETURN_SUCCESS, the caller may continue the rest
|
|
FMP update process.
|
|
If the return status is NOT RETURN_SUCCESS, the caller should stop the FMP
|
|
update process and convert the return status to LastAttemptStatus
|
|
to indicate that FMP update fails.
|
|
The LastAttemptStatus can be got from ESRT table or via
|
|
EFI_FIRMWARE_MANAGEMENT_PROTOCOL.GetImageInfo().
|
|
|
|
Caution: This function may receive untrusted input.
|
|
|
|
@param[in] Image Points to an FMP authentication image, started from EFI_FIRMWARE_IMAGE_AUTHENTICATION.
|
|
@param[in] ImageSize Size of the authentication image in bytes.
|
|
@param[in] PublicKeyData The public key data used to validate the signature.
|
|
@param[in] PublicKeyDataLength The length of the public key data.
|
|
|
|
@retval RETURN_SUCCESS Authentication pass.
|
|
The LastAttemptStatus should be LAST_ATTEMPT_STATUS_SUCCESS.
|
|
@retval RETURN_SECURITY_VIOLATION Authentication fail.
|
|
The LastAttemptStatus should be LAST_ATTEMPT_STATUS_ERROR_AUTH_ERROR.
|
|
@retval RETURN_INVALID_PARAMETER The image is in an invalid format.
|
|
The LastAttemptStatus should be LAST_ATTEMPT_STATUS_ERROR_INVALID_FORMAT.
|
|
@retval RETURN_UNSUPPORTED No Authentication handler associated with CertType.
|
|
The LastAttemptStatus should be LAST_ATTEMPT_STATUS_ERROR_INVALID_FORMAT.
|
|
@retval RETURN_UNSUPPORTED Image or ImageSize is invalid.
|
|
The LastAttemptStatus should be LAST_ATTEMPT_STATUS_ERROR_INVALID_FORMAT.
|
|
@retval RETURN_OUT_OF_RESOURCES No Authentication handler associated with CertType.
|
|
The LastAttemptStatus should be LAST_ATTEMPT_STATUS_ERROR_INSUFFICIENT_RESOURCES.
