# Provides SMM variable service. | |
# | |
# This module installs SMM variable protocol into SMM protocol database, | |
# which can be used by SMM driver, and installs SMM variable protocol | |
# into BS protocol database, which can be used to notify the SMM Runtime | |
# Dxe driver that the SMM variable service is ready. | |
# This module should be used with SMM Runtime DXE module together. The | |
# SMM Runtime DXE module would install variable arch protocol and variable | |
# write arch protocol based on SMM variable module. | |
# | |
# Caution: This module requires additional review when modified. | |
# This driver will have external input - variable data and communicate buffer in SMM mode. | |
# This external input must be validated carefully to avoid security issues such as | |
# buffer overflow or integer overflow. | |
# The whole SMM authentication variable design relies on the integrity of flash part and SMM. | |
# which is assumed to be protected by platform. All variable code and metadata in flash/SMM Memory | |
# may not be modified without authorization. If platform fails to protect these resources, | |
# the authentication service provided in this driver will be broken, and the behavior is undefined. | |
