Bug Description

[Impact]

When producing a new version of some kernels, we need to check for changes that might affect FIPS or other certs and justify why a commit was kept or removed.

To simplify this process we can add an automated check that will abort the kernel preparation and build when such changes exist without a justification.

[Test Plan]

Check if the kernel preparation fails (cranky close) when one of a security certification changes is added.

[Where problems could occur]

No kernels should be affected until we enable this check on each one. Even when enabled, that only affects the kernel preparation and not the resulting kernel.

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1945989

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

This bug is awaiting verification that the linux/5.4.0-90.101 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
