From mboxrd@z Thu Jan 1 00:00:00 1970 From: Brian Pomerantz Subject: [PATCH] [IPV4] Fix secondary IP addresses after promotion Date: Fri, 4 Nov 2005 10:46:33 -0800 Message-ID: <20051104184633.GA16256@skull.piratehaven.org> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Cc: davem@davemloft.net, kuznet@ms2.inr.ac.ru, pekkas@netcore.fi, jmorris@namei.org, yoshfuji@linux-ipv6.org, kaber@coreworks.de, linux-kernel@vger.kernel.org Return-path: To: netdev@vger.kernel.org Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org When 3 or more IP addresses in the same subnet exist on a device and the first one is removed, only the promoted IP address can be reached. Just after promotion of the next IP address, this fix spins through any more IP addresses on the interface and sends a NETDEV_UP notification for that address. This repopulates the FIB with the proper route information.
