selected syslog around enabling IP with IPv6 on DHCP none

Description Gene Czarcinski 2013-09-30 11:54:05 UTC
Description of problem:
Specifying that IPV6 is on with "automatic".  Initialization appears to proceed correctly but the actual interface is not initialized (does not get an IPv6 address).  The following message is in the syslog:

   nm_platform_ip6_address_add: assertion 'plen > 0' failed

Version-Release number of selected component (if applicable):
Fedora 20 alpha,  NetworkManager-0.9.9.0-12.git20130913.fc20.x86_64

How reproducible:
Everytime

Steps to Reproduce:
1.Install
2.Enable IPv6
3.

Actual results:


Expected results:

Comment 1 Gene Czarcinski 2013-09-30 12:06:30 UTC
Note: Manually specifying the IPv6 address works.

Comment 2 Gene Czarcinski 2013-09-30 12:31:29 UTC
I can reproduce this on both real hardware and KVM virtuals.

Comment 3 Dan Williams 2013-09-30 15:56:09 UTC
Any idea what the radvd configuration on your IPv6 router is?

Also, please do this:

sudo dbus-send --system --print-reply --dest=org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.NetworkManager.SetLogging string:"debug" string:""

and reproduce the problem, then attach the syslog/systemd journal output so we can see what's going on with IPv6.

Comment 4 Gene Czarcinski 2013-10-01 13:14:14 UTC
The "router" supporting the local network is running Fedora 18 with dnsmasq 2.65-6 used to provide name, dhcp, and radvd services.  Here are the pertainent configuration values:
#########################################################
domain=lcl

dhcp-range=192.168.18.129,192.168.18.199,255.255.255.0,12h

dhcp-range=fd00:dead:beef:18::100,fd00:dead:beef:18::1fe,64,12h

# dnsmasq will be doing the RA service also
enable-ra
########################################################

This has been and continues to work fine supporting Fedora 18, Fedora 19, and Windows dual stack (IPv4 and IPv6) systems.

Comment 5 Gene Czarcinski 2013-10-01 13:46:50 UTC
Created attachment 805984 [details]
selected syslog around enabling IP with IPv6 on DHCP

This was on real hardware.  I can also do this on a KVM virtual.  In that case, dns, dhcp, and radvd are provided by dnsmasq-2.66-10 running on Fedora 19 host.

Given that I can duplicate this more or less out-of-the-box, you should be able to do that also ... but, maybe I am doing something different.  Currently, I am running my v-m stuff standard F19.

Comment 6 Dan Williams 2013-10-01 20:45:25 UTC
