Description Michael Chapman 2013-11-10 06:06:24 EST
Description of problem:
This SELinux alert prevented GDM from starting at boot. A similar SELinux alert for the "bind" permission was also generated.

Packages involved:

- dbus-1.6.12-1.fc19.x86_64
- gdm-3.8.4-2.fc19.x86_64
- selinux-policy-targeted-3.12.1-74.12.fc19.noarch
SELinux is preventing /usr/bin/dbus-daemon from 'create' accesses on the netlink_selinux_socket .

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

If you believe that dbus-daemon should be allowed create access on the  netlink_selinux_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 dbus-daemon /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

#============= xdm_t ==============

#!!!! This avc is allowed in the current policy
allow xdm_t self:netlink_selinux_socket create;

$ rpm -q selinux-policy
