Could you please try to execute $ restorecon -v ~/.wayland-errors which will fix labeling and you probably will see what is a real reason for the crash. Reopen the bug if you can reproduce it with SELinux errors. Thank you. |
Description of problem: Gnome-shell on wayland is crashing and I am getting selinux denials with confined users. Version-Release number of selected component (if applicable): How reproducible: Seems to happen with multimedia apps most often, but is semi random. Actual results: Wayland crashes - selinux denies writing error log. Not sure if this is a selinux or wayand/sddm problem, but posting the denials DENIAL SELinux is preventing sddm-helper from write access on the file .wayland-errors. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that sddm-helper should be allowed write access on the .wayland-errors 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: # grep sddm-helper /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:xdm_t:s0-s0:c0.c1023 Target Context system_u:object_r:user_home_t:s0 Target Objects .wayland-errors [ file ] Source sddm-helper Source Path sddm-helper Port <Unknown> Host jazz Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-158.7.fc23.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name jazz Platform Linux jazz 4.4.2-301.fc23.x86_64 #1 SMP Tue Feb 23 19:00:38 UTC 2016 x86_64 x86_64 Alert Count 14 First Seen 2015-12-07 14:20:27 MST Last Seen 2016-03-03 05:31:15 MST Local ID 39ddb6dd-944f-40d8-8337-7c1fd81d881e Raw Audit Messages type=AVC msg=audit(1457008275.223:407): avc: denied { write } for pid=11116 comm="sddm-helper" name=".wayland-errors" dev="sda5" ino=918139 scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:user_home_t:s0 tclass=file permissive=0 Hash: sddm-helper,xdm_t,user_home_t,file,write
