2015-08-25MdeModulePkg Variable: Consume the separated VarCheckLibStar Zeng
Since the variable check service has be separated to VarCheckLib from Variable driver, so update Variable driver to consume the separated VarCheckLib.

2015-08-17MdeModulePkg Variable: Handle variable Attributes mismatch caseStar Zeng
between variable HOB and NV storage. Variable HOB may be built by a system that supports and loads variable default, the variables in the HOB will be flush to NV storage after variable write search ready. After that, if the variable's Attributes is changed by someone and system reboots and tries to load default again, the variable Attributes mismatch case between variable HOB and NV storage will appear. Original code did not handle the case correctly, that may eventually cause NV storage contains two valid same variables that will lead to system hang if GetNextVariableName() called.

2013-07-03MdeModulePkg: Variable drivers robustly handle crashes during Reclaim().Star Zeng
PEI variable implementation checks only the variable header signature for validity. This does not seem robust if system crash occurred during previous Reclaim() operation. If the crash occurred while FTW was rewriting the variable FV, the signature could be valid even though the rest of the FV isn't valid. Solution: Add a FaultTolerantWritePei driver to check and provide the FTW last write status, then PEI variable and early phase(before FTW protocol ready) of DXE variable can check the status and determine if all or partial variable data has been backed up in spare block, and then use the backed up data.
