The issue, I believe, was with interfaces that don't have a link-local address (yet) when they are being monitored over the local interface. It was triggered by your netlink patch -- since we now notice new interfaces earlier, we have a good chance to notice them before they get a link-local IPv6. > and that schedules check_interfaces whenever babeld is notifies of > changes by netlink. That looks good, I've applied it with no changes. Note that while this change significantly reduces the race condition, it doesn't eliminate it completely: if an interface goes down and then immediately back up, we might call check_interfaces after it has gone back up, and hence not notice the transition. The solution would be to flush all routes going through the interface whenever we notice that it's gone down, even if it is now back up. -- Juliusz _______________________________________________ Babel-users mailing list [email protected] https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/babel-users
