What is a labeling for nvidiactl now on your system? ls -lZ PATHTO/nvidiactl We have a rules which should cover it. I believe we should dontaudit it if a labeling is correct. # ls -lZ /dev/nvidiactl crw-rw-rw-. 1 root root system_u:object_r:device_t:s0 195, 255 Dec 9 21:39 /dev/nvidiactl Fedora 22 changed to end-of-life (EOL) status on 2016-07-19.

Description of problem: SELinux is preventing /usr/lib64/firefox/plugin-container from read, write access on the chr_file nvidiactl. ***** Plugin mozplugger (87.7 confidence) suggests ************************ If you want to use the plugin package Then you must turn off SELinux controls on the Firefox plugins. Do # setsebool -P unconfined_mozilla_plugin_transition 0 ***** Plugin device (12.1 confidence) suggests **************************** If you want to allow plugin-container to have read write access on the nvidiactl chr_file Then you need to change the label on nvidiactl to a type of a similar device. Do # semanage fcontext -a -t SIMILAR_TYPE 'nvidiactl' # restorecon -v 'nvidiactl' ***** Plugin catchall (1.66 confidence) suggests ************************** If you believe that plugin-container should be allowed read write access on the nvidiactl 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: # grep plugin-containe /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context unconfined_u:unconfined_r:mozilla_plugin_t:s0-s0:c 0.c1023 Target Context system_u:object_r:device_t:s0 Target Objects nvidiactl [ chr_file ] Source plugin-containe Source Path /usr/lib64/firefox/plugin-container Port <Unknown> Host (removed) Source RPM Packages firefox-41.0-4.fc22.x86_64 Target RPM Packages Policy RPM selinux-policy-3.13.1-128.13.fc22.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.1.7-200.fc22.x86_64 #1 SMP Mon Sep 14 20:19:24 UTC 2015 x86_64 x86_64 Alert Count 33 First Seen 2015-09-26 09:36:31 HKT Last Seen 2015-09-28 14:39:40 HKT Local ID 01826567-89b1-4bd7-840a-2c4d7383e208 Raw Audit Messages type=AVC msg=audit(1443422380.841:615): avc: denied { read write } for pid=11679 comm="plugin-containe" name="nvidiactl" dev="devtmpfs" ino=21071 scontext=unconfined_u:unconfined_r:mozilla_plugin_t:s0-s0:c0.c1023 tcontext=system_u:object_r:device_t:s0 tclass=chr_file permissive=0 type=SYSCALL msg=audit(1443422380.841:615): arch=x86_64 syscall=open success=no exit=EACCES a0=7fff5a101a10 a1=2 a2=7fff5a101a1e a3=0 items=0 ppid=2767 pid=11679 auid=1000 uid=1000 gid=1000 euid=1000 suid=1000 fsuid=1000 egid=1000 sgid=1000 fsgid=1000 tty=(none) ses=1 comm=plugin-containe exe=/usr/lib64/firefox/plugin-container subj=unconfined_u:unconfined_r:mozilla_plugin_t:s0-s0:c0.c1023 key=(null) Hash: plugin-containe,mozilla_plugin_t,device_t,chr_file,read,write Version-Release number of selected component: selinux-policy-3.13.1-128.13.fc22.noarch Additional info: reporter: libreport-2.6.2 hashmarkername: setroubleshoot kernel: 4.1.7-200.fc22.x86_64 type: libreport Potential duplicate: bug 681924
