Doc Text:
Cause: If assigning of ip address through DHCPv4 fails initscript exits with error. Consequence: Static IPv4 and IPv6 addresses are not set if DHCPv4 fails. Fix: Add option IPV4_FAILURE_FATAL. This option lets user decide whether the script should continue or exit if DHCPv4 fails. Also if set to "no" and DHCPv6 is enabled in the configuration file, script tries to get IPv6 address even if DHCPv4 fails. Result: User has more control of what happens when DHCPv4 fails

Description Konstantin Volkov 2012-06-28 12:49:38 UTC 
Description of problem:

Static IPV4 and IPV6 addresses are not set to interface if DHCPv4 failed for this interface

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

initscripts-9.03.31-2.el6

How reproducible:

100%

Steps to Reproduce:
1. Configure the eth0 as DHCP + static IPV4 + static IPV6:

---
CT-106-bash-4.1# cat /etc/sysconfig/network-scripts/ifcfg-eth0 
DEVICE="eth0"
ONBOOT="yes"
BOOTPROTO="static"
DHCPV6C="no"
IPV6INIT="yes"
IPV6ADDR_SECONDARIES="2001:aaad::a1d:8290/64"
IPADDR="1.1.1.2"
NETMASK=""
---

2. service network restart (or ifup eth0)
3. see that both IPV4 and IPV6 addresses are not assigned if dhcpv4 client failed
  
Actual results:

---
CT-106-bash-4.1# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:1C:42:FE:07:84  
          inet6 addr: fe80::21c:42ff:fefe:784/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:3551808 errors:0 dropped:0 overruns:0 frame:0
          TX packets:144 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:302572596 (288.5 MiB)  TX bytes:20662 (20.1 KiB)

---


Expected results:

Both static addresses are assigned to eth0

Additional info:

The problem is in /etc/sysconfig/network-scripts/ifup-eth :


[...]
     if /sbin/dhclient ${DHCLIENTARGS} ${DEVICE} ; then
        echo $" done."
    else
        echo $" failed."
        exit 1
    fi

as you can see, all work stopped if dhclient failed. Please, fix.
