Description Kelsey Cummings 2011-04-28 17:49:17 UTC
Description of problem:

In previous versions 'ifup lo:N' would correctly bring up the configured alias on lo.  In 6, it exits without any error message but fails to bring up the alias. If 'ifup lo' is called, it will bring up all aliases it finds.

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


How reproducible:
very

Steps to Reproduce:

create config

#cat > /etc/sysconfig/network-scripts/ifcfg-lo:2
DEVICE=lo:2
IPADDR=10.73.43.12
NETMASK=255.255.255.255
NAME=lo:2

#ifup lo:2

Actual results:

lo:2 not configured

Expected results:

lo:2 configured

What version of initscripts?

Comment 3 Kelsey Cummings 2011-04-28 18:38:05 UTC
initscripts-9.03.17-1.el6

Comment 4 Bill Nottingham 2011-04-28 19:23:16 UTC
I can't reproduce this here:

[root@localhost network-scripts]# rpm -q initscripts
initscripts-9.03.17-1.el6.x86_64
[root@localhost network-scripts]# cat ifcfg-lo:2
DEVICE=lo:2
IPADDR=172.31.4.0
NETMASK=255.255.255.0
ONBOOT=yes
NAME=loopback

After 'service network restart':

 [root@localhost network-scripts]# ip addr ls dev lo
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet 172.31.4.0/24 brd 172.31.4.255 scope global lo:2
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever

Comment 5 Kelsey Cummings 2011-04-28 21:12:09 UTC
It functions correctly after a reboot and/or "service network restart" - a service impacting event - presumably because the aliases are brought up at the same time as the parent interface.  However, "ifup lo:2" does not bring up the alias. "ifup lo" will correctly bring up it and any other configured aliases.  

But consider:

# cat /etc/sysconfig/network-scripts/ifcfg-lo:1
DEVICE=lo:1
IPADDR=1.1.1.1
NETMASK=255.255.255.248
ONPARENT=no
NAME=lo:1

This alias shouldn't be brought up automatically but explicitly with "ifup lo:1".

Comment 6 RHEL Program Management 2011-04-29 06:01:37 UTC
Since RHEL 6.1 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.

Can you please check this behavior in current initscripts? I have tried your configuration and it seems to work fine:


[root@localhost ~]# rpm -q initscripts
initscripts-9.03.31-2.el6.x86_64
[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-lo:1
DEVICE=lo:1
IPADDR=1.1.1.1
NETMASK=255.255.255.248
ONPARENT=no
NAME=lo:1
[root@localhost ~]# ip addr ls dev lo
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
[root@localhost ~]# ifup lo:1
[root@localhost ~]# ip addr ls dev lo
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet 1.1.1.1/29 brd 1.1.1.7 scope global lo:1
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
