Message-Id: <1392061264-28124-124-git-send-email-kamal@canonical.com> Date: Mon, 10 Feb 2014 11:41:03 -0800 From: Kamal Mostafa <kamal@...onical.com> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org, kernel-team@...ts.ubuntu.com Cc: Nicolas Dichtel <nicolas.dichtel@...nd.com>, Kamal Mostafa <kamal@...onical.com> Subject: [PATCH 3.8 123/124] Revert "ip6tnl: fix use after free of fb_tnl_dev" 3.8.13.18 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Nicolas Dichtel <nicolas.dichtel@...nd.com> [ No relevant upstream commit. ] This reverts commit 22c3ec552c29cf4bd4a75566088950fe57d860c4. This patch is not the right fix, it introduces a memory leak when a netns is destroyed (the FB device is never deleted).
