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