SELinux is preventing /usr/libexec/gdm-crash-logger from 'append' accesses on the file /var/log/gdm/:0-slave.log. ***** Plugin catchall (50.5 confidence) suggests *************************** If you believe that gdm-crash-logger should be allowed append access on the :0-slave.log 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 gdm-crash-logge /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp ***** Plugin leaks (50.5 confidence) suggests ****************************** If you want to ignore gdm-crash-logger trying to append access the :0-slave.log file, because you believe it should not need this access. Then you should report this as a bug. You can generate a local policy module to dontaudit this access.
