This is a note to let you know that I have just added a patch titled sched/debug: Fix sd->*_idx limit range avoiding overflow 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 37b5925faa3c5ee3b373d860e1af5e10a7c082dd Mon Sep 17 00:00:00 2001 From: libin <huawei.libin@huawei.com> Date: Mon, 8 Apr 2013 14:39:12 +0800 Subject: [PATCH] sched/debug: Fix sd->*_idx limit range avoiding overflow commit fd9b86d37a600488dbd80fe60cca46b822bff1cd upstream. Commit 201c373e8e ("sched/debug: Limit sd->*_idx range on sysctl") was an incomplete bug fix. This patch fixes sd->*_idx limit range to [0 ~ CPU_LOAD_IDX_MAX-1] avoiding array overflow caused by setting sd->*_idx to CPU_LOAD_IDX_MAX on sysctl.
