Alex Sidorenko reported for problems with local routes left after IP addresses are deleted. It happens when same IPs are used in more than one subnet for the device. Fix fib_del_ifaddr to restrict the checks for duplicate local and broadcast addresses only to the IFAs that use our primary IFA or another primary IFA with same address. And we expect the prefsrc to be matched when the routes are deleted because it is possible they to differ only by prefsrc. This patch prevents local and broadcast routes to be leaked until their primary IP is deleted finally from the box. As the secondary address promotion needs to delete the routes for all secondaries that used the old primary IFA, add option to ignore these secondaries from the checks and to assume they are already deleted, so that we can safely delete the route while these IFAs are still on the device list.
