[edk2-devel] [PATCH v6 00/14] Add the VariablePolicy feature

Posted by Bret Barkelew 2 weeks ago
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(the code branches shared in that discussion are now out of date, but the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).

Re: [edk2-devel] [PATCH v6 00/14] Add the VariablePolicy feature

Posted by Dandan Bi 1 week ago
Hi Bret,

Thanks for the contribution.

I have taken an overview of this patch series and have some small comments in the related patches, please check in sub-patch.

I will review the patch series more in details and bring more comments back if have. Do you have a branch for these patches in GitHub? Which should be easy for review.


Thanks,
Dandan

Re: [edk2-devel] [PATCH v6 00/14] Add the VariablePolicy feature

Posted by Bret Barkelew via groups.io 1 week ago
Certainly do:
https://github.com/corthon/edk2/tree/var_policy_dev_submission_v6

I’ve already made a change from some of your feedback in that branch and will restructure the patches for v7 once all feedback is in.
Thanks!

Re: [edk2-devel] [PATCH v6 00/14] Add the VariablePolicy feature

Posted by Bret Barkelew via groups.io 1 week ago
Actually, if you want to leave feedback in the CI test PR that I made for this version, I’m happy to discuss there as well.

Certainly do:

I’ve already made a change from some of your feedback in that branch and will restructure the patches for v7 once all feedback is in.
Thanks!

Hi Bret,

Thanks for the contribution.

I have taken an overview of this patch series and have some small comments in the related patches, please check in sub-patch.

I will review the patch series more in details and bring more comments back if have. Do you have a branch for these patches in GitHub? Which should be easy for review.


Thanks,
Dandan
