mrl5 Posted October 13, 2019 Report Share Posted October 13, 2019 some questions regarding @drobbins announcement: https://forums.funtoo.org/topic/2997-selinux-packages-updated-in-14-and-selinux-next-development/ 1. If I (as funtoo user) report bugs (found on funtoo machine) to Gentoo Hardened SELinux project . Do I also need to report them to bugs.funtoo.org? (example: FL-6753 and 697564). Thats not a problem for me but I don't know what about devs? 2. I think that I found one sec-policy bug related to nvidia which I suspect is funtoo specific. I connect it with this change Quote Another important change for NVIDIA proprietary graphics users -- a new package nvidia-kernel-modules is now used to install the NVIDIA kernel modules. nvidia-drivers will only install the userland components. but I can't tell if it's valid for Gentoo and should I bother @perfinion from #gentoo-hardened EDIT: regarding Q#2 if someone is interested in logs: I believie it's /dev/nvidiactl related $ startx # cat /var/log/Xorg.0.log [ 4173.919] X.Org X Server 1.20.5 X Protocol Version 11, Revision 0 [ 4173.919] Build Operating System: Linux 4.19.67_p2-r1-debian-sources-lts x86_64 Gentoo [ 4173.920] Current Operating System: Linux pc 4.19.67_p2-r1-debian-sources-lts #1 SMP Fri Sep 27 13:23:14 CEST 2019 x86_64 [ 4173.920] Kernel command line: BOOT_IMAGE=/kernel-debian-sources-lts-x86_64-4.19.67_p2-r1 real_root=/dev/sdc6 rootfstype=ext4 rand_id=FI38EHQ7 pci=nocrs security=selinux enforcing=1 [ 4173.921] Build Date: 11 October 2019 06:19:53PM [ 4173.921] [ 4173.921] Current version of pixman: 0.34.0 [ 4173.921] Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.

mrl5 Posted October 15, 2019 Author Report Share Posted October 15, 2019 regarding question #2: I've found this cool blogpost and method described there fixes the problem. All I have to do is to run this command after every boot restorecon /dev/nvidiactl /dev/nvidia0 at this moment I've added it to /etc/init.d/xdm but I'll dig further for better solution so the question no #1 is still open. @drobbins any thoughts? EDIT: Q#1: answered here Q#2: opened bug FL-6772 related to OpenRC Link to comment Share on other sites More sharing options...

mrl5 Posted April 12, 2020 Author Report Share Posted April 12, 2020 (edited) @zdavatz so I've checked your nvidia thread and I did not see any info that you are using SELinux. This forum topic is SELinux related and the described issue was fixed in FL-6772 Sorry if I missed something - did you cross-link this thread because of similarities in logs or there is some other reason? (EE) NVIDIA: Failed to initialize the NVIDIA kernel module BTW when I experienced this bug I was on kernel version 4 (4.9 afair) and you mentioned problems with 5.6 that do not occur in 5.5 BTW2 I see that gentoo did not merge my fix yet: https://github.com/gentoo/gentoo/pull/13350 and the bug is still open in their bugzilla: https://bugs.gentoo.org/697886 Edited April 12, 2020 by mrl5 Link to comment Share on other sites More sharing options...
