Description of problem:
SELinux is preventing /usr/lib64/xulrunner/plugin-container from 'name_bind' accesses on the tcp_socket .

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

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

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

If you believe that plugin-container should be allowed name_bind access on the  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 Daniel Walsh 2013-10-16 15:13:19 EDT
Itamar can you run this in permissive mode and see if any other access is required.
Comment 2 Daniel Walsh 2013-10-16 15:14:55 EDT
f17dc4436ba87b23190277e7eca3ff531c187768 in git will allow this if the mozilla_plugin_use_spice boolean is set.
Comment 3 Itamar Heim 2013-10-16 15:45:30 EDT
so the strange part i don't remember launching spice-xpi when i saw these errors.
i tried launching it even with enforcing mode but saw no issues reported.
Comment 4 Daniel Walsh 2013-10-16 16:28:04 EDT
Could be unrelated, and I went to far.   Were you playing with some kind of remote vnc application?
Comment 5 Itamar Heim 2013-10-25 08:23:45 EDT
no. i'm pretty sure i didn't use virt-viewer or spice-xpi at the time.
we can close if doesn't reproduce to me or anyone else i guess
