Subject: radvd and auto-ipv6 address regression from 2.6.31 to 2.6.34+
Date: Fri, 05 Nov 2010 14:24:50 -0700	[thread overview]
Message-ID: <4CD47622.5040507@candelatech.com> (raw)


I'm seeing something strange.  I'm running radvd on a VETH interface (veth0 for argument)
with a single global IPv6 address (and a link-local address).

On hacked 2.6.31, this works as I expect:  The veth0 interface does not gain or lose any
IPv6 addresses and peer VETH port gets an auto-created IPv6 addresses.

On hacked 2.6.34 and 2.6.36 kernels, however, the veth0 gains a new address that appears
to be generated similar to other IPs associated with auto-creation via radvd.

I have not yet tested intervening kernels or physical interfaces between two machines.

So, the question is:  Is the new behaviour on purpose, or is it a regression bug?

Thanks,
Ben
