Bug Description

lsb_release -rd
Description: Ubuntu 14.04.4 LTS
Release: 14.04

apt-cache policy ifupdown

  Installed: 0.7.47.2ubuntu4.4
  Candidate: 0.7.47.2ubuntu4.4

ifupdown of ucarp interface fails if the interface name >=16 chars.

Example configuration,

bond0.1234:ucarp

/usr/share/ucarp/vip-up bond0.1234 10.10.20.2

RTNETLINK answers: Numerical result out of range
Failed to bring up bond0.1234:ucarp.

To work around this issue,
1) Rename the bond0.1234:ucarp interface manually in /etc/network/interfaces file to bond0.1234:u
2) Edit /usr/share/ucarp/vip-up and /usr/share/ucarp/vip-down script
to use the modified interface name.

/sbin/ifup $1:u

This issue affects all ucarp interfaces on vlans > 999.
