https://bugzilla.tianocore.org/show_bug.cgi?id=2522 TcgMorLockSmm provides special protections for the TCG MOR variables. This will check IsVariablePolicyEnabled() before enforcing them to allow variable deletion when policy engine is disabled. Only allows deletion, not modification.

# 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.
