This is a note to let you know that I have just added a patch titled ipv6: clean up dev_snmp6 proc entry when we fail to initialize inet6_dev to the linux-3.19.y-queue branch of the 3.19.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.19.y-queue This patch is scheduled to be released in version 3.19.8-ckt11. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.19.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From ed15e341b7cee08916551886008444a01c280a35 Mon Sep 17 00:00:00 2001 From: Sabrina Dubroca <sd@queasysnail.net> Date: Wed, 4 Nov 2015 14:47:53 +0100 Subject: ipv6: clean up dev_snmp6 proc entry when we fail to initialize inet6_dev [ Upstream commit 2a189f9e57650e9f310ddf4aad75d66c1233a064 ] In ipv6_add_dev, when addrconf_sysctl_register fails, we do not clean up the dev_snmp6 entry that we have already registered for this device. Call snmp6_unregister_dev in this case.
