Per the UEFI specification, if the Request argument in EFI_HII_CONFIG_ACCESS_PROTOCOL.ExtractConfig() is NULL or does not contain any request elements, the implementation should return all of the settings being abstracted for the particular ConfigHdr reference. The current implementation returns EFI_INVALID_PARAMETER if Request is NULL or does not contain any request elements. Instead, construct a new ConfigRequest to handle these cases per the specification. In addition, per the UEFI specification, if the Configuration argument in EFI_HII_CONFIG_ACCESS_PROTOCOL.RouteConfig() has a ConfigHdr that specifies a non-existing target, the implementation should return EFI_NOT_FOUND. The current implementation returns EFI_INVALID_PARAMETER if Configuration has a non-existing target in ConfigHdr. Instead, perform a check and return EFI_NOT_FOUND in this case.
