Miller" , Stable Subject: [PATCH for-4.9.y 0/5] net/sched: init failure fixes Date: Wed, 1 Aug 2018 00:10:00 +0530 Message-Id: <1533062405-32524-1-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 4.9.116 for ARCH=arm/arm64. 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 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 | 7 +------ net/sched/sch_netem.c | 4 ++-- net/sched/sch_tbf.c | 5 +++-- 5 files changed, 12 insertions(+), 12 deletions(-) -- 2.7.4
