[PATCH] ALSA: firewire-digi00x: fix memory leak of private data

by Takashi Sakamoto

Although private data of sound card instance is usually allocated in the tail of the instance, drivers in ALSA firewire stack allocate the private data before allocating the instance. In this case, the private data should be released explicitly at .private_free callback of the instance. This commit fixes memory leak following to the above design.

[stable PATCH 1/2] arm64: Fix mismatched cache line size detection

by Suzuki K Poulose

commit 4c4a39dd5fe2d13e2d2fa5fceb8ef95d19fc389a upstream If there is a mismatch in the I/D min line size, we must always use the system wide safe value both in applications and in the kernel, while performing cache operations. However, we have been checking more bits than just the min line sizes, which triggers false negatives. We may need to trap the user accesses in such cases, but not necessarily patch the kernel. This patch fixes the check to do the right thing as advertised. A new capability will be added to check mismatches in other fields and ensure we trap the CTR accesses.

[PATCH v2 for-4.9.y 0/5] net/sched: init failure fixes

by Amit Pundir

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

[PATCH 1/2] USB: serial: option: improve Quectel EP06 detection

by Johan Hovold

From: Kristian Evensen <kristian.evensen(a)gmail.com> The Quectel EP06 (and EM06/EG06) LTE modem supports updating the USB configuration, without the VID/PID or configuration number changing. When the configuration is updated and interfaces are added/removed, the interface numbers are updated. This causes our current code for matching EP06 not to work as intended, as the assumption about reserved interfaces no longer holds. If for example the diagnostic (first) interface is removed, option will (try to) bind to the QMI interface. This patch improves EP06 detection by replacing the current match with two matches, and those matches check class, subclass and protocol as well as VID and PID. The diag interface exports class, subclass and protocol as 0xff. For the other serial interfaces, class is 0xff and subclass and protocol are both 0x0. The modem can export the following devices and always in this order: diag, nmea, at, ppp. qmi and adb. This means that diag can only ever be interface 0, and interface numbers 1-5 should be marked as reserved. The three other serial devices can have interface numbers 0-3, but I have not marked any interfaces as reserved. The reason is that the serial devices are the only interfaces exported by the device where subclass and protocol is 0x0. QMI exports the same class, subclass and protocol values as the diag interface. However, the two interfaces have different number of endpoints, QMI has three and diag two. I have added a check for number of interfaces if VID/PID matches the EP06, and we ignore the device if number of interfaces equals three (and subclass is set).
