Bug Description
Given an ipv6 configured iface in /etc/network/
properly because the ipv6 module is not loaded and an autoload is not triggered
by ifupdown.

As we discussed on irc:
<fabbione> mdz: the ipv6 bug was a note for myself. it's not a kernel or
ifupdown bug. simply nothing triggers the load of the module early
enough to let ifupdown configure the ipv6 interface.
<mdz> fabbione: shouldn't the act of configuring the ipv6 interface cause the
module to load?
<fabbione> and and ifconfig recognize the fact that the family isn't supported
and exit quietly
<fabbione> but it's my todo list with low priority since it's not a feature
goal

Is this still an issue with Breezy/Dapper?

IIRC it was in breezy. I totally forgot about this bug since it's so low priority...
I will try to get it ficed for dapper if it is still there.

Changing to confirmed, as Fabio has acknowledged the bug. :)

Have you been able to look at this, Fabio? Is it still a problem?
Thanks

This is a catch 22 for people that don't want IPv6 on their system. Yes the issue has always been there but i am not going to fix it for dapper. I might for dapper+1.

Ping for edgy
Can you please give us the current status of the bug? Is it fixed in Edgy/ Feisty?
| Mattias Wadenstein (maswan) wrote : | #11 |
Not fixed in Edgy, not fixed in Feisty.
It is also a concern because you can't switch autoconf off until the module is loaded, so you kind of need it before sysctl.conf is read (unless you want ugly pre-up and up hacks).

Fixed in feisty by modprobing ipv6 when inet6 family is requested on one interface.

I think this should be reopened (or another bug opened, I don't know). I can't put an ipv6 settings in /etc/sysctl.conf (eg. net/ipv6/
My workaround is to put ipv6 in /etc/modules.
(this also affects people who want to for example deactivate autoconfiguration via RA globally)
It seems odd to give you your own bug, but you are the resident IPv6 expert, I
think :-)
Is this an ifupdown problem or a kernel problem? I don't think that ifupdown
should need to do anything explicitly for the module to be autoloaded. Is it a
kernel problem, then?
