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. > > Reported-by: Alex Sidorenko <alexandre.sidorenko@...com> > Signed-off-by: Julian Anastasov <ja@....bg> Applied. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
