There actually was a recent followup in this bug (#417757). It seems that Firefox has an alleged workaround for this, but so far we don't have anyone who had time to take a look for the general eglibc case.

Right now, IPv4 is tried first, but the IPs are only committed to the
interface and routing is set once IPv6 has received an address or
timed out (timed out, in the case I just tested). My testing gave me a
delay of 30 seconds between the interface going up ("eth0: Link is up
at 100 Mbps, full duplex" log from the driver) to the IP being set and
me being able to ping Google (and ntp's message about syncing the
clock).
It's pretty high, but I think this can be fixed by committing IPs and
routes as soon as IPv4 comes up; and it's an issue we can work on
during the cycle. I've discussed this on IRC with the NM developers, a
couple of ideas have come up.

The default settings are still to only get IPv4 by default and require that something responds to bring up the interface, but you can turn this requirement off, enable IPv6, turns *its* requirement off, or turn IPv4 address requests off altogether. For Natty enabling IPv6 addresses in NM still requires manual intervention: you need to set a drop-down to Automatic or whatever you want it to be; and choose whether it needs to respond to bring up the interface. For Oneiric, my plan is to change that default for new interfaces to Automatic IPv6 and not requiring IPv4 or IPv6 to bring up interfaces, which should make almost everyone happy. > > Any other major roadblock beside the above?

I *think* this should be fine on the desktop side, but I haven't tested IPv6-only, just dual-stack. The main problem is that if you're relying on only IPv6, you will still not reach a whole lot of things on the Internet, including some of our infrastructure: for instance, cdimage.u.c doesn't appear to have addresses.

I think the most important bit is going to be automated testing of common use cases. We need to be able to fire up a VM on an IPv6 only subnet, install LAMP, give it an IPv6 address, have it send an email to an IPv6 enabled MX, have it trigger an IPv6 client to pull a page from it, then start Firefox, and have it run through some automated scripts (Selenium anybody?) to drive an IPv6 website. > > Finally, a question to consider is whether we want to address the > IPv6-only use-case (ie, not dual-stack, no IPv4 configuration).

Given the IPv4 space exhaustion problem, we can reasonably expect to see it all used up by 2019, which is when the presumably-next-LTS 12.04 will reach EOL on the server. So I think IPv6 only networks are a simple goal that will definitely become a reality in the lifetime of upcoming releases. -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
[Oneiric topic] IPv6
Hello everyone, I have been having one-on-one conversation in the past few weeks with a number of people around the question of IPv6 in Ubuntu. With the upcoming IPv4 armageddon, I think it is quite pressing that we make sure that we have good end-to-end IPv6 support in Ubuntu. I've been asked to kickstart a discussion about it, and eventually distil the results in a blueprint for the next UDS. So, here are my notes on the stuff that would need to be investigated: - Installer support: some work has been done upstream in netcfg and d-i[1]. Not sure about the status. I do not think Ubiquity has any IPv6 support (or does it?) - NFS: I was never able to make that work in Ubuntu. Reportedly, it requires nfs-utils 1.2.3, which just got uploaded to Debian. I also believe nfs-utils needs to be built with --enable-ipv6. - DHCPv6: I understand we are getting that in Natty with isc-dhcp v4. I know SLAAC is the way to go in most case, but some people wants/needs DHCPv6 for various reasons. I guess it mostly needs testing. - NetworkManager: It used to be that NetworkManager insisted upon getting an IPv4 address, but Matt Trudel just marked bug #307598 as fixed two weeks ago. Presumably, NM now work fine in IPv6-only network, but I have not tested yet. Any other major roadblock beside the above? I am going to sift through the bugs tagged ipv6 on Launchpad, but if there's anything obvious I missed, please let me know. Finally, a question to consider is whether we want to address the IPv6-only use-case (ie, not dual-stack, no IPv4 configuration). This has some implications, notably around d-i and NetworkManager. Few networks are IPv6-only at this time, but it's bound to change in the near future. Thanks for your insights.
