MdeModulePkg: Variable drivers robustly handle crashes during Reclaim().

[mirror_edk2.git] / MdeModulePkg / Universal / Variable / RuntimeDxe / VariableSmm.inf

## @file
#  Component description file for SMM Variable module.
#
#  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 issue like
#  buffer overflow, integer overflow.
