Package: avahi-autoipd Version: 0.6.17-3 Severity: normal Tags: patch With this package installed, ifdown wlan0 takes 10 seconds to run. This makes downing and upping dhcp when moving to a different network much slower than it needs to be. I used to ifdown; ifup when resuming from sleep, but that's impractical when the ifdown takes this long to run.
ps shows:
27108 pts/3 S+ 0:00 | \_ ifdown wlan0
27134 pts/3 S+ 0:00 | \_ dhclient3 -r -pf
/var/run/dhclient.wlan0.pid -lf /var/lib/dhcp3/dhclient.wlan0.leases wlan0
27135 pts/3 S+ 0:00 | \_ /bin/bash
/sbin/dhclient-script
27140 pts/3 S+ 0:00 | \_
/usr/sbin/avahi-autoipd -wD wlan0
AFAIK this hook is only useful if dhclient failed to receive an address,
not when the link is being taken down.
According to the dhclient-script man page, the $exit_status variable
should be passed to the dhclient-exit-hooks script. However, in my
testing, zzz_avahi-autoipd does not see that. The man page also
documents though that the hooks will be run with RELEASE if the admin
wants it to drop its lease. So this patch will avoid the delay:

With that patch, ifdown takes less than 1 second.
