Apr 03 12:58:29 fedora setroubleshoot[6882]: SELinux hindert plymouthd daran, mit map-Zugriff auf chr_file /dev/dri/card0 zuzugreifen.
***** Plugin catchall (100. Wahrscheinlichkeit) schlägt vor **************
Wenn Sie denken, dass es plymouthd standardmäßig erlaubt sein sollte, map Zugriff auf card0 chr_file zu erhalten.
Dann sie sollten dies als Fehler melden.
Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen.
Ausführen
zugriff jetzt erlauben, indem Sie die nachfolgenden Befehle ausführen:
# ausearch -c 'plymouthd' --raw | audit2allow -M my-plymouthd
# semodule -X 300 -i my-plymouthd.pp
I'm also encountering this on Silverblue 38. In my case it's /dev/dri/card1.
mai 03 10:16:54 fedora audit[607]: AVC avc: denied { map } for pid=607 comm="plymouthd" path="/dev/dri/card1" dev="devtmpfs" ino=583 scontext=system_u:system_r:kernel_t:s0 tcontext=system_u:object_r:dri_device_t:s0 tclass=chr_file permissive=0
I have an encrypted LUKS disk and instead of the password prompt to unlock the drive on boot, both my monitors are off. If I "blindly" type the password and hit Enter, the disk gets decrypted and the boot process continues.
This worked fine on Silverblue 37.

Description of problem: Booted and logged in, happens in Xfce and Cinnamon. SELinux is preventing plymouthd from 'map' accesses on the chr_file /dev/dri/card0. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that plymouthd should be allowed map access on the card0 chr_file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'plymouthd' --raw | audit2allow -M my-plymouthd # semodule -X 300 -i my-plymouthd.pp Additional Information: Source Context system_u:system_r:kernel_t:s0 Target Context system_u:object_r:dri_device_t:s0 Target Objects /dev/dri/card0 [ chr_file ] Source plymouthd Source Path plymouthd Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages SELinux Policy RPM selinux-policy-targeted-38.8-1.fc39.noarch Local Policy RPM selinux-policy-targeted-38.8-1.fc39.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 6.3.0-0.rc0.20230302gitee3f96b16468.12.fc39.x86_64 #1 SMP PREEMPT_DYNAMIC Thu Mar 2 16:05:30 UTC 2023 x86_64 Alert Count 1 First Seen 2023-03-04 12:02:40 AEDT Last Seen 2023-03-04 12:02:40 AEDT Local ID c216ffed-dde1-48b7-84f0-ee14c20e7b9e Raw Audit Messages type=AVC msg=audit(1677891760.806:83): avc: denied { map } for pid=375 comm="plymouthd" path="/dev/dri/card0" dev="devtmpfs" ino=378 scontext=system_u:system_r:kernel_t:s0 tcontext=system_u:object_r:dri_device_t:s0 tclass=chr_file permissive=1 Hash: plymouthd,kernel_t,dri_device_t,chr_file,map Version-Release number of selected component: selinux-policy-targeted-38.8-1.fc39.noarch Additional info: reporter: libreport-2.17.7 reason: SELinux is preventing plymouthd from 'map' accesses on the chr_file /dev/dri/card0. package: selinux-policy-targeted-38.8-1.fc39.noarch component: selinux-policy hashmarkername: setroubleshoot type: libreport kernel: 6.3.0-0.rc0.20230302gitee3f96b16468.12.fc39.x86_64 comment: Booted and logged in, happens in Xfce and Cinnamon. component: selinux-policy
