Note that userspace could override and do something with the zero source address before the kernel ever gets to see it. This behavior in the kernel is in line with how socket binding works, and it's not a bad fallback in the case where we do see a zero tunnel source addres which frankly has no other sane semantic than the one Patrick has given to it. The main point is that putting zero tunnel source address handling into the kernel does not preclude at all userspace doing something interesting with it as well. Therefore I think Patrick's initial kernel patch makes a lot of sense. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
