Description of problem:
SELinux is preventing /usr/lib64/firefox/plugin-container from 'read' accesses on the lnk_file .

*****  Plugin mozplugger (99.1 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 catchall (1.81 confidence) suggests   **************************

If you believe that plugin-container should be allowed read access on the  lnk_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 Browser /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 jakub.kopriva 2014-05-20 23:56:56 UTC
I am not absolutely sure what concern this error message and I think that

1.) mozplugger (99.1 confidence) 
is Streaming Multimedia Plugin for Unix Mozilla Plugger 5.1.3 http://fredrik.hubbe.net/plugger.html

I want my firefox browser to play multimedia files
so I ran suggested
# setsebool -P unconfined_mozilla_plugin_transition 0


2.) Plugin catchall (1.81 confidence)
is general plugin-container process

I dont know if restriced access on lnk_file by default should be bug. What access to a linked file was restricted?
If "langpack-cs.org.xpi"
I have no problem running suggested

# grep Browser /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

rather than turning off SELinux watching any /usr/lib64/firefox/plugin-container activity.

Comment 2 jakub.kopriva 2014-05-21 00:01:38 UTC
Or maybe this error message was caused because of using encrypted home directory?

Yes. Could you please try to run


$ restorecon -R -v ~/


to see if it fixes labeling. Thank you.

Thanks, I tried.
Actually that message bug appeared only once as I launched firefox. Before it I restarted after updating via 'yum update kernel* selinux-policy*'

Comment 5 Daniel Walsh 2014-05-25 10:37:38 UTC
Did the relabel fix the problem?

I think running
restorecon -R -v ~/
was not necessary but whatever caused that problem it never appeared again.

Comment 7 Miroslav Grepl 2014-05-30 10:57:23 UTC
I am fixing

*_ecryptfs_home_dirs

booleans.

Comment 10 jakub.kopriva 2014-06-16 15:38:52 UTC
I reinstalled fedora 20 completely and replaced gnome desktop with xfce and system is now much faster. 
Yes I ran 
# su -c 'yum update --enablerepo=updates-testing selinux-policy-3.12.1-167.fc20'
also.
Now I don't receive error messages about kernel.

I have SELinux-policy is set to Enforcing by default.
Would I receive SELinux error messages if I set SELinux policy to Permissive?
Is that caused because of using xfce instead of gnome version?
