Bug 1318 – net scripts don't properly release dhcp lease on interface shutdown

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Jim Nutt 2002-03-23 10:50:53 UTC]

When a network interface controlled by dhcp is shutdown, the dhcp lease is not
being released and dhcpcd is not being killed. This causes problems with pcmcia
and hotplug interfaces as they are not completely shutdown on eject.

Can't seem to attach the file with the updated /etc/init.d/net.eth0. Here is the
pertinent section:

        /sbin/ifconfig ${IFACE} down &>/dev/null
        if [ "$(eval echo \$\{iface_${IFACE}\})" == "dhcp" ]
        then
                /sbin/dhcpcd -k ${IFACE} &>/dev/null 
        fi
        eend 0

It goes after the alias shutdown code in the stop() section.

It looks like this fix is (sorta) already on our internal CVS.  The only 
difference is that our version doesn't using ifconfig to bring the interface 
down if it's dhcp (the first line in your script snippet is not executed).  Is 
this correct or does the ifconfig line need to execute either way?

[Comment 3 Jim Nutt 2002-03-23 12:14:53 UTC]

ifconfig down does need to be execute in both cases. If you don't do it before
the dhcpcd -k, the dhcpcd -k fails..

Fixed in baselayout-1.7.5.  Thanks! :)
