We should not require loading keys into firmware for user built kernel modules. An OS-level module should be trustable at the OS kernel level. Thus, it should be: MS cert -> shim -> Fedora cert -> grub -> kernel -> user cert -> user kmod. > 3 - Your complaint describes solution: import NVIDIA's signing key > into your firmware.

As a live streamer, for example, I need to use v4l2loopback, which will never exist in mainline because v4l2 maintainers don't like it at all. Broad non-Mac hardware only became available after Windows 8 / Windows Server 2012 R2. Yes, some hardware existed a few years before, but it was not broadly available before 2013. We didn't discontinue i686 in Fedora until Fedora Linux 31, which was over 15 years after the first x86_64 system. The user experience with x86_64 was immeasurably better than i686 at that point in time. We do not have a better experience with UEFI *right now*. I know of plenty of people intentionally choosing BIOS because the user experience is better, even though it's older/bad technology. Because using BIOS means kmods work. Because using BIOS means hibernate works. Because using BIOS means they can get an equivalent experience leveraging their hardware that they can get on Windows today with UEFI. Maybe none of you proposing this Change use these things, but I'm telling you these things matter. And the amount of resistance to improving UEFI experience for hardware is amazingly awful. The workstation working group has tried to figure out ways to improve the experience, only to be simultaneously stymied by the UEFI firmware management tools and unwillingness by anyone involved to even consider that we should make this better. I will *not* force people to deal with importing keys into firmware. It's brittle, buggy, and often completely broken on motherboards. Many of those UEFI implementations are extremely buggy and terrible. I've dealt with a lot of it as part of my job over the years and it leads to a terrible user experience for Linux users. If you are making UEFI the only way people boot, ***fix*** the experience. If you're not committed to that, then you're causing more pain for no gain. -- 真実はいつも一つ！/ Always, there's only one truth! _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
