dhcpcd-discuss

Hi

I'm using the dhcpcd.enter-hook to send dbus notifications when the ip
address changes, like so:

--snip--
log() {
        date=$(date +"%Y%m%d-%H%M%S")
        file="/tmp/dhcpcdlog"
        echo "$date $1" >> $file
}

log "dhcpcd hook: interface:[$interface] ifcarrier:[$ifcarrier]
reason:[$reason]"

if [ "$reason" = "STATIC" ] \
|| [ "$reason" = "BOUND" ] \
|| [ "$reason" = "REBIND" ] \
|| [ "$reason" = "REBOOT" ] \
|| [ "$reason" = "IPV4LL" ]; then
    log "Interface ${interface} UP. IPv4 address: ${new_ip_address}"
    /path_to/config_routes.sh postup ${interface}
    /path_to/config_firewall.sh dev-reconf ${interface}

    dbus-send --session --type="method_call" \
              --dest=com.our.application \
                /ObjectName \
                com.our.application.LinkUpDownMethod \
                string:${interface} \
                boolean:true \
                string:"IPChange" \
                string:${new_ip_address}
fi
--snip--

This seems to work well for IPv4, but not for IPv6. For IPv6, I get
unexpected calls for the "ROUTERADVERT" reason and I can't see a way
to detect the address change in a similar way to IPv4.

Is there a way to do this? Could someone explain it to me?

There's a diagram for the states as I currently understand it at:
