Something relevant is obviously changed in the kernel >= 4.10.x, be it upstream or downstream, considering that Secure boot works seamlessly with the kernel <= 4.9.x. Actually, secure boot doesn't work since a bug in grub causes the secure boot flag worked out in the efi boot wrapper to get sanitised away before the main kernel gets to see it. See bug 1418360. (In reply to David Howells from comment #2) > Actually, secure boot doesn't work since a bug in grub causes the secure > boot flag worked out in the efi boot wrapper to get sanitised away before > the main kernel gets to see it. See bug 1418360. Thank you for your response, I left a comment there. *** This bug has been marked as a duplicate of bug 1418360 *** This bz isn't really a duplicate of the grub bug. The error message you have an issue with is from the kernel's EFI boot wrapper, saying that it can't manage to determine the secure boot status from the UEFI BIOS. What happens in the kernel is: (1) The EFI boot wrapper stores a flag in boot_params to note the outcome of the secure boot mode determination. This is where the "EFI stub: ERROR: Could not determine UEFI Secure Boot status." is emitted. (2) The decompressor calls sanitize_boot_params(), which sees that the boot_params were incorrectly set up by grub and clears parts of boot_params, including the secure_boot flag. This is bug 1418360. (3) In the main kernel, setup_arch() looks at the flag and sees the cleared value. This bug is related to https://bugzilla.redhat.com/show_bug.cgi?id=1418360 therefore it remains open until the origin resolves. Ref. https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/log/drivers/firmware/efi/libstub/secureboot.c We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. The kernel moves very fast so bugs may get fixed as part of a kernel update. Due to this, we are doing a mass bug update across all of the Fedora 26 kernel bugs. Fedora 26 has now been rebased to 4.15.4-200.fc26. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 27, and are still experiencing this issue, please change the version to Fedora 27. If you experience different issues, please open a new bug report for those. This message is a reminder that Fedora 26 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '26'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 26 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 26 changed to end-of-life (EOL) status on 2018-05-29. Fedora 26 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. The needinfo request[s] on this closed bug have been removed as they have been unresolved for 1000 days |
