This is a note to let you know that I have just added a patch titled Btrfs: fix access_ok() check in btrfs_ioctl_send() to the linux-3.11.y-queue branch of the 3.11.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-3.11.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 3.11.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From d032f34a9743e96eea5d894dcba271cdec455316 Mon Sep 17 00:00:00 2001 From: Dan Carpenter <dan.carpenter@oracle.com> Date: Thu, 10 Jan 2013 03:57:25 -0500 Subject: Btrfs: fix access_ok() check in btrfs_ioctl_send() commit 700ff4f095d78af0998953e922e041d75254518b upstream. The closing parenthesis is in the wrong place. We want to check "sizeof(*arg->clone_sources) * arg->clone_sources_count" instead of "sizeof(*arg->clone_sources * arg->clone_sources_count)".
