2016-10-13net_sched: reorder pernet ops and act ops registrationsWANG Cong1-8/+11
Krister reported a kernel NULL pointer dereference after tcf_action_init_1() invokes a_o->init(), it is a race condition where one thread calling tcf_register_action() to initialize the netns data after putting act ops in the global list and the other thread searching the list and then calling a_o->init(net, ...). Fix this by moving the pernet ops registration before making the action ops visible. This is fine because: a) we don't rely on act_base in pernet ops->init(), b) in the worst case we have a fully initialized netns but ops is still not ready so new actions still can't be created.

2016-10-13xen-netback: fix guest Rx stall detection (after guest Rx refactor)David Vrabel1-0/+2
If a VIF has been ready for rx_stall_timeout (60s by default) and an Rx ring is drained of all requests an Rx stall will be incorrectly detected. When this occurs and the guest Rx queue is empty, the Rx ring's event index will not be set and the frontend will not raise an event when new requests are placed on the ring, permanently stalling the VIF. This is a regression introduced by eb1723a29b9a7 (xen-netback: refactor guest rx). Fix this by reinstating the setting of queue->last_rx_time when placing a packet onto the guest Rx ring.

The Quectel EC21 and EC25 need the same "set DTR" request as devices based on the MDM9230 chipset, but has no USB3 support. Our best guess is that the "set DTR" functionality depends on chipset and/or baseband firmware generation. But USB3 is still an optional feature. Since we cannot enable this unconditionally for all older devices, and there doesn't appear to be anything we can use in the USB descriptors to identify these chips, we are forced to use a device specific quirk flag.

It is useful to be able to see the hash configuration when running tests. This patch adds a debugfs node for that purpose. The original version of this patch (commit c0c64c152389) was reverted due to build failures caused by a conflict with commit 0364a8824c02 ("xen-netback: switch to threaded irq for control ring"). This new version of the patch is nearly identical to the original, the only difference being that creation of the debugfs node is predicated on 'ctrl_irq' being non-zero rather then the now non-existent 'ctrl_task'.

2016-10-13net_sched: do not broadcast RTM_GETTFILTER resultEric Dumazet1-7/+11
There are two ways to get tc filters from kernel to user space. 1) Full dump (tc_dump_tfilter()) 2) RTM_GETTFILTER to get one precise filter, reducing overhead. The second operation is unfortunately broadcasting its result, polluting "tc monitor" users. This patch makes sure only the requester gets the result, using netlink_unicast() instead of rtnetlink_send() Jamal cooked an iproute2 patch to implement "tc filter get" operation, but other user space libraries already use RTM_GETTFILTER when a single filter is queried, instead of dumping all filters.

2016-10-13cpufreq: conservative: Fix next frequency selectionRafael J. Wysocki1-3/+16
Commit d352cf47d93e (cpufreq: conservative: Do not use transition notifications) overlooked the case when the "frequency step" used by the conservative governor is small relative to the distances between the available frequencies and broke the algorithm by using policy->cur instead of the previously requested frequency when computing the next one. As a result, the governor may not be able to go outside of a narrow range between two consecutive available frequencies. Fix the problem by making the governor save the previously requested frequency and select the next one relative that value (unless it is out of range, in which case policy->cur will be used instead).

2016-10-12fscrypto: make XTS tweak initialization endian-independentEric Biggers1-7/+8
The XTS tweak (or IV) was initialized differently on little endian and big endian systems. Because the ciphertext depends on the XTS tweak, it was not possible to use an encrypted filesystem created by a little endian system on a big endian system and vice versa, even if they shared the same PAGE_SIZE. Fix this by always using little endian. This will break hypothetical big endian users of ext4 or f2fs encryption. However, all users we are aware of are little endian, and it's believed that "real" big endian users are unlikely to exist yet. So this might as well be fixed now before it's too late.

2016-10-12drm/amdgpu: use .early_unregister hook to remove DP AUX i2cGrazvydas Ignotas1-1/+12
When DisplayPort AUX channel i2c adapter is registered, drm_connector's kdev member is used as a parent, so we get sysfs structure like: /drm/card1/card1-DP-2/i2c-12 Because of that, there is a problem when drm core (and not the driver) calls drm_connector_unregister(), it removes parent sysfs entries ('card1-DP-2' in our example) while the i2c adapter is still registered. Later we get a WARN when we try to unregister the i2c adapter: WARNING: CPU: 3 PID: 1374 at fs/sysfs/group.c:243 sysfs_remove_group+0x14c/0x150 sysfs group ffffffff82911e40 not found for kobject 'i2c-12' To fix it, we can use the .early_unregister hook to unregister the i2c adapter before drm_connector's sysfs is torn down.

2016-10-12ACPI / PAD: don't register acpi_pad driver if running as Xen dom0Juergen Gross1-0/+5
When running as Xen dom0 a special processor_aggregator driver is needed. Don't register the standard driver in this case. Without that check an error message: "Error: Driver 'processor_aggregator' is already registered, aborting..." will be displayed.

2016-10-12cpufreq: intel_pstate: Proportional algorithm for AtomRafael J. Wysocki1-1/+21
The PID algorithm used by the intel_pstate driver tends to drive performance to the minimum for workloads with utilization below the setpoint, which is undesirable, so replace it with a modified "proportional" algorithm on Atom. The new algorithm will set the new P-state to be 1.25 times the available maximum times the (frequency-invariant) utilization during the previous sampling period except when the target P-state computed this way is lower than the average P-state during the previous sampling period. In the latter case, it will increase the target by 50% of the difference between it and the average P-state to prevent performance from dropping down too fast in some cases. Signed-off-by: Rafael J.

This commit is a fix for Linux 4.9-rc1. In former commit, a function call of compatibility layer for ALSA sequencer core was obsoleted by an alternative. Although, the alternative gets a pointer to kernel stack due to mis-programming. As a result, ALSA sequencer core unexpectedly refers over kernel stack.

2016-10-12ALSA: hda - Fix a failure of micmute led when having multi adcsHui Wang2-2/+2
On a Dell laptop, there is no global adcs for all input devices, so the input devices use the different adc, as a result, dyn_adc_switch is set to true. In this situation, it is safe to control the micmute led according to user's choice of muting/unmuting the current input device, since only current input device path is active, while other input device paths are inactive and powered down.

git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux Pull thermal managament updates from Zhang Rui: - Enhance thermal "userspace" governor to export the reason when a thermal event is triggered and delivered to user space. From Srinivas Pandruvada - Introduce a single TSENS thermal driver for the different versions of the TSENS IP that exist, on different qcom msm/apq SoCs'. Support for msm8916, msm8960, msm8974 and msm8996 families is also added. From Rajendra Nayak - Introduce hardware-tracked trip points support to the device tree thermal sensor framework. The framework supports an arbitrary number of trip points. Whenever the current temperature is changed, the trip points immediately below and above the current temperature are found, driver callback is invoked to program the hardware to get notified when either of the two trip points are triggered. Hardware-tracked trip points support for rockchip thermal driver is also added at the same time. From Sascha Hauer, Caesar Wang - Introduce a new thermal driver, which enables TMU (Thermal Monitor Unit) on QorIQ platform. From Jia Hongtao - Introduce a new thermal driver for Maxim MAX77620. From Laxman Dewangan - Introduce a new thermal driver for Intel platforms using WhiskeyCove PMIC. From Bin Gao - Add mt2701 chip support to MTK thermal driver. From Dawei Chien - Enhance Tegra thermal driver to enable soctherm node and set "critical", "hot" trips, for Tegra124, Tegra132, Tegra210. From Wei Ni - Add resume support for tango thermal driver.
