Reverting the patch fixes it again. Tested on 9.2-RC2 and 9.1-RELEASE-p*. Same behaviour. A tcpdump shows the broadcast to 255.255.255.255 port 67 for the address request including my MAC address and the reply from the dhcp server, however dhclient just times every time. >How-To-Repeat: Apply the patch for CVE-2013-3077 to 9.1 or 9.2 and try to use dhclient to obtain an IP address. >Fix: Revert the patch (which is probably not what people really want). >Release-Note: >Audit-Trail: >Unformatted:
