Message-ID: <20130624200328.GJ13836@order.stressinduktion.org> Date: Mon, 24 Jun 2013 22:03:28 +0200 From: Hannes Frederic Sowa <hannes@...essinduktion.org> To: netdev@...r.kernel.org Cc: dborkman@...hat.com Subject: [PATCH net-next] ipv6: remove old token ipv6 address as soon as possible If the tokenized ip address is re-set on an interface we depend on the arrival of a new router advertisment to call addrconf_verify to clean up the old address (which valid_lft is now set to 0). Old addresses can linger around for a longer time if e.g. the source of router advertisments vanishes. So, call addrconf_verify immediately after setting the new tokenized address to get rid of the old tokenized addresses.
