Description Dan Mossor [danofsatx] 2013-12-21 06:47:47 UTC 
Created attachment 839925 [details]
messages log containing error on restart of NetworkManager

Description of problem: 

 No IPv4 addresses are being assigned via DHCP to the network interfaces.

Version-Release number of selected component (if applicable):

 dhclient-4.2.5-28.fc21.x86_64
 NetworkManager-0.9.9.0-19.git20131003.fc21.x86_64

How reproducible:

 Every time.

Steps to Reproduce:
1. Activate a network interface configured to receive an address via DHCP.
2. Wait patiently.
3. Discover that no IPv4 address was assigned.

Actual results:

 No IPv4 address assigned to interface, effectively blocking all network access (IPv6 was not tested due to other issues with IPv6 registration).

Expected results:

 IPv4 address assigned by the DHCP server, allowing system to communicate on the network.

This is an SELinux issue; check the journal for errors from auditctl. If you do 'setenforce Permissive' it works.
