Developer checklist

• In the "Related issues" section, write down the GitLab Runner Security issue it belongs to (i.e. Related to <issue_id>).
• Merge request targets master, or a versioned stable branch (X-Y-stable).
• Milestone is set for the version this merge request applies to. A closed milestone can be assigned via quick actions.
• Title of this merge request is the same as for all backports.
• For the MR targeting master:
  • Assign to a reviewer and maintainer, per our Code Review process.
  • Ensure it's approved according to our Approval Guidelines.
  • Ensure it's approved by an AppSec engineer.
    • If you're unsure who should approve, find the AppSec engineer associated to the issue in the Canonical repository, or ask #sec-appsec on Slack.
  • Merge request must close the corresponding security issue.
• Ensure that a backport MR targeting a versioned stable branch (X-Y-stable) is approved by a maintainer.

Note: Reviewer/maintainer should not be a Release Manager

Maintainer checklist

• Correct milestone is applied and the title is matching across all backports.
• Assign the merge request to the release manager of the upcoming security release with passing CI pipelines and when all backports including the MR targeting master are ready.
