VariableSmmIsBufferOutsideSmmValid function is to check the buffer is outside SMM or not. This patch fix the issue that always return true for MM. Meanwhile, this patch renames VariableSmmIsBufferOutsideSmmValid to VariableSmmIsNonPrimaryBufferValid.

# 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.
