** Changed in: shim-signed (Ubuntu)
Status: New => Fix Committed
** Description changed:
- The version of MokManager currently in xenial-updates and later supports
- a MokTimeout variable, which can be set with mokutil --timeout, to
- control how long MokManager waits for input instead of having a hard-
- coded timeout of 10 seconds.
+ [SRU Justification]
+ The version of MokManager currently in all releases supports a MokTimeout
variable, which can be set with mokutil --timeout, to control how long
MokManager waits for input instead of having a hard-coded timeout of 10 seconds.
If the timeout is reached on boot with no input, MokManager clears the
MOK requests and passes control back to shim, which falls back to
booting the OS.
So if you miss seeing MokManager on boot, you have to restart the key
enrollment process from the OS and reboot again.
When we are invoking mokutil automatically on behalf of the user as part
of key generation for dkms modules, we should disable the timeout. We
should never leave the user with broken dkms modules on the system
because they were looking away from the console at the wrong point in
time during a reboot.
+
+ [Test case]
+ 1. On a system with SecureBoot enabled, install the virtualbox-dkms package.
+ 2. Set a password to use for MOK enrollment.
+ 3. Reboot.
+ 4. Observe that there is a countdown on MokManager. Let the timer expire.
+ 5. Install the shim-signed package from -proposed.
+ 6. Purge the virtualbox-dkms and dkms packages.
+ 7. sudo rm -rf /var/lib/shim-signed.
+ 8. Repeat steps 1 through 3.
+ 9. Observe that there is no countdown on MokManager, and that it waits
indefinitely for input (confirm that this is the case by sitting at the screen
for at least 1 minute).
