This is a note to let you know that I have just added a patch titled ipv6: don't call addrconf_dst_alloc again when enable lo to the linux-3.5.y-queue branch of the 3.5.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 108fd11b5810b93ab1c4c3dfcf081f481f3da243 Mon Sep 17 00:00:00 2001 From: Gao feng <gaofeng@cn.fujitsu.com> Date: Sun, 16 Jun 2013 11:14:30 +0800 Subject: [PATCH] ipv6: don't call addrconf_dst_alloc again when enable lo commit a881ae1f625c599b460cc8f8a7fcb1c438f699ad upstream. If we disable all of the net interfaces, and enable un-lo interface before lo interface, we already allocated the addrconf dst in ipv6_add_addr. So we shouldn't allocate it again when we enable lo interface. Otherwise the message below will be triggered. unregister_netdevice: waiting for sit1 to become free. Usage count = 1 This problem is introduced by commit 25fb6ca4ed9cad72f14f61629b68dc03c0d9713f "net IPv6 : Fix broken IPv6 routing table after loopback down-up" Signed-off-by: Gao feng <gaofeng@cn.fujitsu.com> Signed-off-by: David S.
