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.
Now applied for 4.4.y and 4.9.y, thanks.
