Description of problem:
This must happen when I enable some plugins requeste by Blue Jeans.
SELinux is preventing /usr/lib64/firefox/plugin-container from 'name_bind' accesses on the tcp_socket port 5994.

*****  Plugin mozplugger (89.7 confidence) suggests   ************************

If you want to use the plugin package
Then you must turn off SELinux controls on the Firefox plugins.
# setsebool -P unconfined_mozilla_plugin_transition 0

*****  Plugin catchall_boolean (10.0 confidence) suggests   ******************

If you want to allow mozilla to plugin use spice
Then you must tell SELinux about this by enabling the 'mozilla_plugin_use_spice' boolean.
You can read 'None' man page for more details.
setsebool -P mozilla_plugin_use_spice 1

*****  Plugin catchall (1.69 confidence) suggests   **************************

If you believe that plugin-container should be allowed name_bind access on the port 5994 tcp_socket by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep plugin-containe /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2015-08-27 13:13:03 EDT
Yes, there is a bug with handling of bluejans boolean. Not sure what the correct solution is. We need to review these mozilla_plugins booleans.
