This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- trusty' to 'verification-done-trusty'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

Unfortunately, links browser does not present me with a Log in button
during apport-collect authorization, therefore I cannot add the details
to this bug. Therefore changing the status of the bug to 'Confirmed' as
suggested.
** Changed in: linux (Ubuntu)
Status: Incomplete = Confirmed
** Tags added: apport-collected
** Description changed:
Dear all,
a regression has been introduced in Linux Kernels by patch
https://github.com/torvalds/linux/commit/efe4208f47f907
The regression behaves in a way that when there are multiple IPv6
sockets created with multicast/link-local addresses on the same
interface, handling of the packets is broken. (Reported e. g. on
http://www.spinics.net/lists/netdev/msg286344.html)
This can be reproduced by
1. installing Ubuntu 14.04 with default kernel
2. installing dibbler-server and configuring with basic dhcpv6 settings (hand
out one subnet), for example:
/etc/dibbler/server.conf:
log-level 8
preference 0
iface IFACE {
t1 1800-2000
t2 2700-3000
prefered-lifetime 3600
valid-lifetime 7200
subnet 2001:db8:abcd::/64
class {
pool 2001:db8:abcd::1000-2001:db8:abcd::1fff
}
ta-class {
pool 2001:db8:abcd::2000-2001:db8:abcd::2fff
}
option dns-server 2001:db8:abcd::1
}
3. get a DHCPv6 client and request addresses from the server
4. view the packets on the interface affected, use e.g.: tcpdump -i IFACE
'(udp port 546)||(udp port 547)' -n
There will be multicast DHCPv6 solicits, however no DHCPv6 responses, as
Dibbler creates two sockets on the same interface (multicast socket first,
link-local socket next).
There is a patch available in the upstream, that will be probably merged
to 3.15.2 kernel (it is not present in current 3.15.1 vanilla kernel) -
http://patchwork.ozlabs.org/patch/352246/
When applying this patch to trusty-proposed linux-
image-3.13.0-30-generic_3.13.0-30.54 from Git repositories at git clone
git://kernel.ubuntu.com/ubuntu/ubuntu-trusty.git and recompiling the
kernel, everything starts to work as expected.
- Please apply this patch ASAP to fix IPv6 multicast, there is more and
- more IPv6 in the wild and this bug is a serious one.
