[edk2-devel] [PATCH v5 00/14] Add the VariablePolicy feature
Posted by Bret Barkelew 5 years, 8 months 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(the code branches shared in that discussion are now out of date, but the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).

Thank you very much for your willingness to learn the mailing list based
workflow, even if that workflow is on its way out. I highly appreciate it!

Re: [EXTERNAL] [edk2-devel] [PATCH v5 00/14] Add the VariablePolicy feature
Posted by Bret Barkelew via groups.io 5 years, 8 months ago 
Bump.
Now that the stable tag is behind us, I’d like to get this in to have maximum time before the next stable tag.

I think the only reviews I’ve seen so far are for the platform integrations (Arm, Ovmf, and Embedded). Need more eyeballs, please and thank you!

Subject: [EXTERNAL] [edk2-devel] [PATCH v5 00/14] Add the VariablePolicy feature

REF:https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbugzilla.tianocore.org%2Fshow_bug.cgi%3Fid%3D2522&amp;data=02%7C01%7Cbret.barkelew%40microsoft.com%7C90bcb822fa054686203008d807a3e4ee%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637267747784879051&amp;sdata=k9X9qPTDTQlno5%2Ff4koMn6bE9s6nTOIlJ886PQRw%2Bzc%3D&amp;reserved=0

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://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Ftianocore%2Ftianocore.github.io%2Fwiki%2FVariablePolicy-Protocol---Enhanced-Method-for-Managing-Variables%23platform-porting&amp;data=02%7C01%7Cbret.barkelew%40microsoft.com%7C90bcb822fa054686203008d807a3e4ee%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637267747784879051&amp;sdata=eIQjfZJQGTECXzETa1iZ3T9vOdNiNEjIzVrjhDR%2B2CE%3D&amp;reserved=0

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://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fedk2.groups.io%2Fg%2Fdevel%2Fmessage%2F53712&amp;data=02%7C01%7Cbret.barkelew%40microsoft.com%7C90bcb822fa054686203008d807a3e4ee%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637267747784879051&amp;sdata=rhwUXzkU%2B71sFkomJvPzi4IN6hz2JKIbDBnNt0wCJS8%3D&amp;reserved=0
(the code branches shared in that discussion are now out of date, but the
whitepapers and discussion are relevant).

Re: [EXTERNAL] [edk2-devel] [PATCH v5 00/14] Add the VariablePolicy feature
Posted by Guomin Jiang 5 years, 7 months ago 
Hi Bret,

I plan to review it and give feedback before 7/31.

Thanks and Sorry for inconveniences.

Best Regards.

Bump.
Now that the stable tag is behind us, I'd like to get this in to have maximum time before the next stable tag.

I think the only reviews I've seen so far are for the platform integrations (Arm, Ovmf, and Embedded). Need more eyeballs, please and thank you!

- Bret

Subject: [EXTERNAL] [edk2-devel] [PATCH v5 00/14] Add the VariablePolicy feature

REF:https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbugzilla.tianocore.org%2Fshow_bug.cgi%3Fid%3D2522&amp;data=02%7C01%7Cbret.barkelew%40microsoft.com%7C90bcb822fa054686203008d807a3e4ee%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637267747784879051&amp;sdata=k9X9qPTDTQlno5%2Ff4koMn6bE9s6nTOIlJ886PQRw%2Bzc%3D&amp;reserved=0

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://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Ftianocore%2Ftianocore.github.io%2Fwiki%2FVariablePolicy-Protocol---Enhanced-Method-for-Managing-Variables%23platform-porting&amp;data=02%7C01%7Cbret.barkelew%40microsoft.com%7C90bcb822fa054686203008d807a3e4ee%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637267747784879051&amp;sdata=eIQjfZJQGTECXzETa1iZ3T9vOdNiNEjIzVrjhDR%2B2CE%3D&amp;reserved=0

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://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fedk2.groups.io%2Fg%2Fdevel%2Fmessage%2F53712&amp;data=02%7C01%7Cbret.barkelew%40microsoft.com%7C90bcb822fa054686203008d807a3e4ee%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637267747784879051&amp;sdata=rhwUXzkU%2B71sFkomJvPzi4IN6hz2JKIbDBnNt0wCJS8%3D&amp;reserved=0
(the code branches shared in that discussion are now out of date, but the
whitepapers and discussion are relevant).

Re: [edk2-devel] [PATCH v5 00/14] Add the VariablePolicy feature
Posted by Leif Lindholm 5 years, 8 months ago 
Hi Bret,

I don't have any comments on the content of these patches, but I have
a couple about metadata:
You're submitting the patches from bret@corthon.org, but signing them
off with Bret Barkelew <brbarkel@microsoft.com>.

This way the Microsoft authorship metadata is not preserved, which I
think is unfortunate. It also leaves the relationship between
bret@corthon.com and brbarkel@microsoft.com somewhat unofficial.

If this is exactly as intended, feel free to stop reading here.

If not, I have some suggestions.

- It would be a good clarification if one of you could submit a patch
  to edk2/.mailmap associating the addresses, and the other giving it
  a Reviewed-by.
- Can we use brbarkel@microsoft.com as the author of the patches?
  I'm sure whoever stages this set as a pull request would be happy to
  do it this time around, but for future sets, if you set up local git
  configuration for edk2 with user.email as @microsoft.com, you should
  still be able to set (local or global) sendemail.from as
  @corthon.com.

Finally, it would be nice if bret@corthon.com could "become a member"
of edk2.groups.io, and then set the subscription to "no email". This
way, you don't get duplicated emails, but it lets us add the corthon
address to the sender whitelist, so your patches stop getting stuck in
moderation.

Best Regards,

Leif

Happy to take a look at that, and thanks for all the tips.

I had tried to register an email address for groups.io that had a “+edk” so that I could filter the emails to be forwarded differently, but it won’t send from that address so that’s probably causing some confusion.

Yes, I would prefer to use brbarkel@microsoft.com<mailto:brbarkel@microsoft.com> as the committer. Thanks!
