Miller" , Stable Subject: [PATCH v2 for-4.9.y 0/5] net/sched: init failure fixes Date: Thu, 23 Aug 2018 12:20:36 +0530 Message-Id: <1535007041-31605-1-git-send-email-amit.pundir@linaro.org> Sender: stable-owner@vger.kernel.org List-ID: Hi Greg, Kindly consider/review following net/sched fixes for stable 4.9.y. This patchset is a follow-up of upstream fix 87b60cfacf9f ("net_sched: fix error recovery at qdisc creation") cherry-picked on stable 4.9.y. It fix null pointer dereferences due to uninitialized timer (qdisc watchdog) or double frees due to ->destroy cleaning up a second time. Here is the original submission https://www.mail-archive.com/netdev@vger.kernel.org/msg186003.html Cherry-picked and build tested on Linux 4.9.123 for ARCH=x86_64. These fixes are applicable for stable 4.4.y kernel as well, but one of the patches needed a minor rebasing, so I'm resending this series for 4.4.y in a separate thread to avoid any confusion. Regards, Amit Pundir Change since v1: Rebased "sch_multiq: fix double free on init failure" patch and fixed "unused variable" build warning. Nikolay Aleksandrov (5): sch_htb: fix crash on init failure sch_multiq: fix double free on init failure sch_hhf: fix null pointer dereference on init failure sch_netem: avoid null pointer deref on init failure sch_tbf: fix two null pointer dereferences on init failure net/sched/sch_hhf.c | 3 +++ net/sched/sch_htb.c | 5 +++-- net/sched/sch_multiq.c | 9 ++------- net/sched/sch_netem.c | 4 ++-- net/sched/sch_tbf.c | 5 +++-- 5 files changed, 13 insertions(+), 13 deletions(-) -- 2.7.4
