:SELinux is preventing /usr/lib64/xulrunner-2/plugin-container from using the 'ipc_lock' capabilities.
:*****  Plugin catchall (100. confidence) suggests  ***************************
:If you believe that plugin-container should have the ipc_lock capability 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 Dennis 2012-08-07 12:42:30 EDT
I was running the google talk client and in a hangout at the time.
Comment 2 Miroslav Grepl 2012-08-08 06:36:47 EDT
Do you have mozilla_plugin_t as permissive domain?

syscall=mlock success=yes
Comment 3 Dennis 2012-08-09 02:21:57 EDT
I haven't changed anything from the stock install.  How do I check?
Comment 4 Daniel Walsh 2012-08-13 15:51:18 EDT
We should dontaudit.  Not sure how this can happen without a setuid app.
Comment 5 Daniel Walsh 2012-08-13 15:52:47 EDT
This could be a case where the SELinux check is done before the DAC check.  The syscall is failing with success, because mlock probably checks the capability and falls back to a safe mode.
