I think that unlike the bug title and description suggest, this bug is not limited to IPv6. I am having the same problem with FreeRADIUS when RADIUS packets are received over IPv4. This problem is fixed by the Kernel from trusty-proposed, too.
Actually, this problem looks a lot like a regression that already appeared in 3.13.0-66 and was fixed in 3.13.0-67 (see bug #1510213 which turned out to be the same problem as tracked in #1508510). So maybe, some measures should be taken to ensure that this regression does not make it into a released kernel again but it is detected during QA. A side note regading the problem with FreeRADIUS: I only had this problem on a multi-core multi-socket machine. On a multi-core single- socket machine, it did not appear, but this might just have been a coincidence. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1527902 Title: 3.13.0-71: IPv6 UDP DNS packets are not received To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1527902/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
