Re: [Bugme-new] [Bug 30462] New: High cpu usage when someone sends many ipv6 udp packages

Hi,

seems like reverting "ipv6: Always clone offlink routes." fixes the issue.

I've only used precompiled kernels so far so I don't have stuff set up to
compile kernels right now,
probably won't have time to do that this weekend. Not tonight in GMT+1
anyway!

The following ipv6 related changes were introduced between -rc2 and
-rc3 that I
can see. The "Revert 'administrative down' address handling changes."
looked
big...
      ipv6: Always clone offlink routes.
      ipv6: Revert 'administrative down' address handling changes.

Can we narrow it down to which of those two changes introduced the
regression?

We have another issue, still open, which is caused by the first
change, so maybe try reverting that one first.

Thanks.
