Description Adam Williamson 2014-02-26 00:54:38 UTC
Description of problem:
Happens on attempt to log in to GNOME (I think) on current Rawhide. Something, possibly this, causes GNOME to fail to start properly unless I do setenforce Permissive.
SELinux is preventing /usr/bin/login from using the 'net_admin' capabilities.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that login should have the net_admin capability 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 login /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
