Hi, The file in the setroubleshoot report has incorrect label. Along with the restorecon plugin suggestion, you can fix the label with a single command: # /sbin/restorecon -v /dev/dri/renderD129 This change will not, however, persist boot. As no new information appeared during the past weeks, we are going to close this bug. If you need to pursue this matter further, feel free to reopen this bug and attach the needed information. |
Description of problem: Simply logged into Xfce from slickgreeter. SELinux is preventing slick-greeter-c from 'getattr' accesses on the chr_file /dev/dri/renderD129. ***** Plugin restorecon (90.5 confidence) suggests ************************ If you want to fix the label. /dev/dri/renderD129 default label should be dri_device_t. Then you can run restorecon. The access attempt may have been stopped due to insufficient permissions to access a parent directory in which case try to change the following command accordingly. Do # /sbin/restorecon -v /dev/dri/renderD129 ***** Plugin device (9.50 confidence) suggests **************************** If you want to allow slick-greeter-c to have getattr access on the renderD129 chr_file Then you need to change the label on /dev/dri/renderD129 to a type of a similar device. Do # semanage fcontext -a -t SIMILAR_TYPE '/dev/dri/renderD129' # restorecon -v '/dev/dri/renderD129' ***** Plugin catchall (1.40 confidence) suggests ************************** If you believe that slick-greeter-c should be allowed getattr access on the renderD129 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 'slick-greeter-c' --raw | audit2allow -M my-slickgreeterc # semodule -X 300 -i my-slickgreeterc.pp Additional Information: Source Context system_u:system_r:xdm_t:s0-s0:c0.c1023 Target Context system_u:object_r:device_t:s0 Target Objects /dev/dri/renderD129 [ chr_file ] Source slick-greeter-c Source Path slick-greeter-c Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages SELinux Policy RPM selinux-policy-targeted-37.8-1.fc37.noarch Local Policy RPM selinux-policy-targeted-37.8-1.fc37.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 5.19.7-300.fc37.x86_64 #1 SMP PREEMPT_DYNAMIC Mon Sep 5 15:09:01 UTC 2022 x86_64 x86_64 Alert Count 1 First Seen 2022-09-07 21:06:31 AEST Last Seen 2022-09-07 21:06:31 AEST Local ID f7754c1d-b7ec-4ec8-8196-8fb4e14c80b9 Raw Audit Messages type=AVC msg=audit(1662548791.142:239): avc: denied { getattr } for pid=2105 comm="slick-greeter-c" path="/dev/dri/renderD129" dev="devtmpfs" ino=1024 scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:device_t:s0 tclass=chr_file permissive=1 Hash: slick-greeter-c,xdm_t,device_t,chr_file,getattr Version-Release number of selected component: selinux-policy-targeted-37.8-1.fc37.noarch Additional info: component: selinux-policy reporter: libreport-2.17.2 hashmarkername: setroubleshoot kernel: 5.19.8-300.fc37.x86_64 type: libreport
