Hmm, that wasn't intentional. I tested that again and so far I still always
got the right source address. I had a little deeper look at ipv6_dev_get_saddr()
and seems like it could get racy the way it is now, so I'm attaching a patch
for that. Thanks for reporting, Jan.

And I hope I didn't cause too much inconvience with the build breakage,
didn't think of testing BRIDGE=y and IPV6=m.

Cheers, Linus
