Title: Fix signing of staging modules in eoan Status in linux package in Ubuntu: In Progress Status in linux source package in Eoan: New Bug description: SRU Justification Impact: Staging drivers should not be signed, apart from a small list of selected modules in drivers/staging/signature-inclusion in the Ubuntu kernel source trees. Changes in eoan to the code which adds .gnu_debuglink sections and re-signs modules broke this, resulting in all staging modules being signed. Fix: Check for a signature on the module before adding the .gnu_debuglink section, and only sign the result if the original was signed. Test Case: Attached script which compares the built modules to the signature inclusion file and prints out any modules which are signed but not expected to be signed, and vice versa. Regression Potential: Unsigned modules cannot be loaded under lockdown, which is automatically enabled under secure boot. Some may have been using erroneously signed modules under secure boot and will no longer be able to do so.
