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-3.8.y-queue branch of the 3.8.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-3.8.y-queue This patch is scheduled to be released in version 3.8.13.6. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.8.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 23be99c094a77c5825ba6300dae0f1f6ba5b8c08 Mon Sep 17 00:00:00 2001 From: Gao feng <gaofeng@cn.fujitsu.com> Date: Sun, 16 Jun 2013 11:14:30 +0800 Subject: ipv6: don't call addrconf_dst_alloc again when enable lo [ Upstream commit a881ae1f625c599b460cc8f8a7fcb1c438f699ad ] 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.
