Hello,

 

The following bug has been fixed on edk2/master

 

    https://bugzilla.tianocore.org/show_bug.cgi?id=3111

    https://github.com/tianocore/edk2/pull/1226

 

This bug is also considered a critical bug against edk2-stable202011.  The behavior

of the Variable Lock Protocol was changed in a non-backwards compatible manner in

edk2-stable202011 and this is impacting some downstream platforms.  The following

2 commits on edk2/master restore the original behavior of the Variable Lock Protocol.

 

    https://github.com/tianocore/edk2/pull/1226/commits/893cfe2847b83da74f53858d6acaa15a348bad7c

    https://github.com/tianocore/edk2/pull/1226/commits/16491ba6a6e9a91cedeeed45bc0fbdfde49f7968

 

The request here is to create a supported branch from edk2-stable202011 tag and apply

these 2 commits as critical bug fixes on the supported branch.

 

Since we started using the edk2-stable* tag process, there has not been a request to create

a supported branch from one of those tags.  As a result, there are a couple opens that

need to be addressed:

 

1) Supported branch naming convention.

 

    Branch Proposal: stable/<YYYY><MM>

    Branch Example:  stable/202011

 

2) CI requirements for supported branches.

 

    Proposal: Update .azurepipelines yml files to trigger on stable/* branches,

    update .mergify configuration file to support merging of stable/* branches,

    and update GitHub branch protection settings to protect stable/* branches.

 

3) A stable/* branch is only supported until the next edk2-stable tag release.

 

4) Release requirements for supported branches.

 

   Proposal: If there are a significant number of critical fixes applied to

   a stable/* branch, then a request for a release can be made that would

   trigger focused testing of the supported branch and creation of a new

   release.  If all testing passes, then a tag is created on the stable/*

   branch and a release is created on GitHub that summarizes the set of

   critical fixes and the testing performed.

 

   Tag Proposal: edk2-stable<YYYY><MM>.<XX>

   Tag Example : edk2-stable202011.01

 

Please let me know if you have any feedback or comments on this proposal.  The goal

is to close on this topic this week.

 

Thank you,

 

Mike
