[edk2-devel] [PATCH v3 00/14] Add the VariablePolicy feature

Posted by Michael Kubacki 3 days ago
From: Michael Kubacki <michael.kubacki@microsoft.com>

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2522

The 14 patches in this series add the VariablePolicy feature to the core,
deprecate Edk2VarLock (while adding a compatibility layer to reduce code
churn), and integrate the VariablePolicy libraries and protocols into
Variable Services.

Since the integration requires multiple changes, including adding libraries,
a protocol, an SMI communication handler, and VariableServices integration,
the patches are broken up by individual library additions and then a final
integration. Security-sensitive changes like bypassing Authenticated
Variable enforcement are also broken out into individual patches so that
attention can be called directly to them.

Platform porting instructions are described in this wiki entry:
https://github.com/tianocore/tianocore.github.io/wiki/VariablePolicy-Protocol---Enhanced-Method-for-Managing-Variables#platform-porting

Discussion of the feature can be found in multiple places throughout
the last year on the RFC channel, staging branches, and in devel.

Most recently, this subject was discussed in this thread:
https://edk2.groups.io/g/devel/message/53712
(the code branches shared in that discussion are now out of date, but the
whitepapers and discussion are relevant).

V3 changes:
* Address all non-unittest issues with ECC
* Make additional style changes
* Include section name in hunk headers in "ini-style" files
* Remove requirement for the EdkiiPiSmmCommunicationsRegionTable driver
  (now allocates its own buffer)
* Change names from VARIABLE_POLICY_PROTOCOL and gVariablePolicyProtocolGuid
  to EDKII_VARIABLE_POLICY_PROTOCOL and gEdkiiVariablePolicyProtocolGuid
* Fix GCC warning about initializing externs
* Add UNI strings for new PCD
* Add patches for ArmVirtPkg, OvmfXen, and UefiPayloadPkg
* Reorder patches according to Liming's feedback about adding to platforms
  before changing variable driver

V2 changes:
* Fixed implementation for RuntimeDxe
* Add PCD to block DisableVariablePolicy
* Fix the DumpVariablePolicy pagination in SMM

On a separate note, shallow threading might not work on this patch series
due to changes made by the SMTP server. I apologize for any inconvenience.
