Description Michal Jaegermann 2007-02-26 17:15:24 EST
Description of problem:

After recent initscripts update starting up a network failed to
rename a machine with a DHCP assigned address from 'localhost'.
The culprit turned out to be ifup-post.  It find address
by doing this:

 IPADDR=$(LANG=C ip -o -4 addr ls dev ${DEVICE} | awk '{ print $4 }')

If ${DEVICE} in question happen to have also some additional alias
addresses this returns all of these and makes a subsequnt call
to 'ipcalc' very unhappy.  A solution is to use only the first address
as reported by 'ip'.  A simple patch is attached.

BTW - earlier in 'ifup-post' there is the following line:

if [ "$PEERDNS" != "no" -o -n "$RESOLV_MODS" -a "$RESOLV_MODS" != "no" ]; then

Is this really what is supposed to be there or rather

if [ "$PEERDNS" != "no" ] || \
     [ -n "$RESOLV_MODS" -a "$RESOLV_MODS" != "no" ]; then

was really meant?  Quite possibly what is there is fine but a logic
is surely not so clear on the first look.
