2 # Provides SMM variable service.
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.
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.
