| | 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 |
