I like the patch, but I want the documentation changed. If you'll recall, one of the big problems Alexey and myself had with the new ARP saddr selection behavior you propose is that it assumes that: if we do not know of a certain subnet being on a link than this subnet does not exist there. In some environments this assumption holds. But "some != all" as I often say to a friend of mine :-) No router has this knowledge completely, and in many environments such an assumption does not hold. I know you understand this, which is why your patch keeps the current behavior the default. But I want the docs for the sysctl to talk about this. Something simple like: + 1 - Try to avoid local addresses that are not in the target's + subnet for this interface as far as we know. In some environments + subnets may be active that this system is not aware of, thus this + setting might cause problems in such cases. Tweak it however you wish, just get the idea/warning across. I'd also prefer if you at least lightly define what "best" source address means in the context of arp_announce==2.
