1## @file 2# Provides SMM variable service. 3# 4# This module installs SMM variable protocol into SMM protocol database, 5# which can be used by SMM driver, and installs SMM variable protocol 6# into BS protocol database, which can be used to notify the SMM Runtime 7# Dxe driver that the SMM variable service is ready. 8# This module should be used with SMM Runtime DXE module together. The 9# SMM Runtime DXE module would install variable arch protocol and variable 10# write arch protocol based on SMM variable module. 11# 12# Caution: This module requires additional review when modified. 13# This driver will have external input - variable data and communicate buffer in SMM mode. 14# This external input must be validated carefully to avoid security issues such as 15# buffer overflow or integer overflow. 16# The whole SMM authentication variable design relies on the integrity of flash part and SMM. 17# which is assumed to be protected by platform. All variable code and metadata in flash/SMM Memory 18# may not be modified without authorization. If platform fails to protect these resources, 19# the authentication service provided in this driver will be broken, and the behavior is undefined. 20# 21# Copyright (c) 2010 - 2016, Intel Corporation.
