1. If PcdMaxAuthVariableSize is set to 0, keep current behavior as is and PcdMaxVariableSize used. 2. If PcdMaxAuthVariableSize is set to non 0, it will work on authenticated variables.

# Runtime DXE part corresponding to SMM authenticated variable module
|
|
#
|
|
# This module installs variable arch protocol and variable write arch protocol to provide
|
|
# variable service. This module need work together with SMM authenticated variable module.
|
|
#
|
|
# Caution: This module requires additional review when modified.
|
|
# This driver will have external input - variable data.
|
|
# 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.
