2018-12-07vxlan: Add vxlan_fdb_clear_offload()Petr Machata
When a driver unoffloads all FDB entries en bloc, it's inefficient to send the switchdev notification one by one. Add a helper that walks the FDB table, unsetting the offload flag on RDST with a given VNI.

2018-12-07vxlan: Add vxlan_fdb_replay()Petr Machata
When a VXLAN device becomes relevant to a driver (such as when it is attached to an offloaded bridge), the driver will generally need to walk the existing FDB entries and offload them. Add a function vxlan_fdb_replay() to call a given notifier block for each FDB entry with a given VNI.

2018-12-07Merge branch 'mlx5-packet-credit-fc' into rdma.gitJason Gunthorpe
Danit Goldberg says: Packet based credit mode Packet based credit mode is an alternative end-to-end credit mode for QPs set during their creation. Credits are transported from the responder to the requester to optimize the use of its receive resources. In packet-based credit mode, credits are issued on a per packet basis. The advantage of this feature comes while sending large RDMA messages through switches that are short in memory. The first commit exposes QP creation flag and the HCA capability. The second commit adds support for a new DV QP creation flag. The last commit report packet based credit mode capability via the MLX5DV device capabilities. * branch 'mlx5-packet-credit-fc': IB/mlx5: Report packet based credit mode device capability IB/mlx5: Add packet based credit mode support net/mlx5: Expose packet based credit mode Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>

The device can support two credit modes, message based (default) and packet based. In order to enable packet based mode, the QP should be created with special flag that indicates this. This patch adds support for the new DV QP creation flag that can be used for RC QPs in order to change the credit mode.

2018-12-07HID: input: use the Resolution Multiplier for high-resolution scrollingPeter Hutterer
Windows uses a magic number of 120 for a wheel click. High-resolution scroll wheels are supposed to use a fraction of 120 to signal smaller scroll steps. This is implemented by the Resolution Multiplier in the device itself. If the multiplier is present in the report descriptor, set it to the logical max and then use the resolution multiplier to calculate the high-resolution events. This is the recommendation by Microsoft, see http://msdn.microsoft.com/en-us/windows/hardware/gg487477.aspx Note that all mice encountered so far have a logical min/max of 0/1, so it's a binary "yes or no" to high-res scrolling anyway. To make userspace simpler, always enable the REL_WHEEL_HI_RES bit. Where the device doesn't support high-resolution scrolling, the value for the high-res data will simply be a multiple of 120 every time. For userspace, if REL_WHEEL_HI_RES is available that is the one to be used. Potential side-effect: a device with a Resolution Multiplier applying to other Input items will have those items set to the logical max as well. This cannot easily be worked around but it is doubtful such devices exist.

2018-12-07HID: core: process the Resolution MultiplierPeter Hutterer
The Resolution Multiplier is a feature report that modifies the value of Usages within the same Logical Collection. If the multiplier is set to anything but 1, the hardware reports (value * multiplier) for the same amount of physical movement, i.e. the value we receive in the kernel is pre-multiplied. The hardware may either send a single (value * multiplier), or by sending multiplier as many reports with the same value, or a combination of these two options. For example, when the Microsoft Sculpt Ergonomic mouse Resolution Multiplier is set to 12, the Wheel sends out 12 for every detent but AC Pan sends out a value of 3 at 4 times the frequency. The effective multiplier is based on the physical min/max of the multiplier field, a logical min/max of [0,1] with a physical min/max of [1,8] means the multiplier is either 1 or 8. The Resolution Multiplier was introduced for high-resolution scrolling in Windows Vista and is commonly used on Microsoft mice. The recommendation for the Resolution Multiplier is to default to 1 for backwards compatibility. This patch adds an arbitrary upper limit at 255. The only known use case for the Resolution Multiplier is for scroll wheels where the multiplier has to be a fraction of 120 to work with Windows.

2018-12-07Input: add `REL_WHEEL_HI_RES` and `REL_HWHEEL_HI_RES`Peter Hutterer
This event code represents scroll reports from high-resolution wheels and is modelled after the approach Windows uses. The value 120 is one detent (wheel click) of movement. Mice with higher-resolution scrolling can send fractions of 120 which must be accumulated in userspace. Userspace can either wait for a full 120 to accumulate or scroll by fractions of one logical scroll movement as the events come in. 120 was picked as magic number because it has a high number of integer fractions that can be used by high-resolution wheels. For more information see https://docs.microsoft.com/en-us/previous-versions/windows/hardware/design/dn613912(v=vs.85) These new axes obsolete REL_WHEEL and REL_HWHEEL. The legacy axes are emulated by the kernel but the most accurate (and most granular) data is available through the new axes.

In addition to the usual HD-audio and USB-audio quirks for various devices, two notable changes are included: - a fix for USB-audio UAF at probing a malformed descriptor - workarounds for PCM rwsem mutex starvation" * tag 'sound-4.20-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: ALSA: hda/realtek: Fix mic issue on Acer AIO Veriton Z4860G/Z6860G ALSA: hda/realtek: Fix mic issue on Acer AIO Veriton Z4660G ALSA: hda/realtek - Add support for Acer Aspire C24-860 headset mic ALSA: hda/realtek: ALC286 mic and headset-mode fixups for Acer Aspire U27-880 ALSA: usb-audio: Fix UAF decrement if card has no live interfaces in card.c ALSA: hda/realtek - Fix speaker output regression on Thinkpad T570 ALSA: pcm: Fix interval evaluation with openmin/max ALSA: hda: Add support for AMD Stoney Ridge ALSA: usb-audio: Add SMSL D1 to quirks for native DSD support ALSA: pcm: Fix starvation on down_write_nonblock() ALSA: pcm: Call snd_pcm_unlink() conditionally at closing

2018-12-06io_pgetevents: use __kernel_timespecDeepa Dinamani
struct timespec is not y2038 safe. struct __kernel_timespec is the new y2038 safe structure for all syscalls that are using struct timespec. Update io_pgetevents interfaces to use struct __kernel_timespec. sigset_t also has different representations on 32 bit and 64 bit architectures. Hence, we need to support the following different syscalls: New y2038 safe syscalls: (Controlled by CONFIG_64BIT_TIME for 32 bit ABIs) Native 64 bit(unchanged) and native 32 bit : sys_io_pgetevents Compat : compat_sys_io_pgetevents_time64 Older y2038 unsafe syscalls: (Controlled by CONFIG_32BIT_COMPAT_TIME for 32 bit ABIs) Native 32 bit : sys_io_pgetevents_time32 Compat : compat_sys_io_pgetevents Note that io_getevents syscalls do not have a y2038 safe solution.

2018-12-06signal: Add restore_user_sigmask()Deepa Dinamani
Refactor the logic to restore the sigmask before the syscall returns into an api. This is useful for versions of syscalls that pass in the sigmask and expect the current->sigmask to be changed during the execution and restored after the execution of the syscall. With the advent of new y2038 syscalls in the subsequent patches, we add two more new versions of the syscalls (for pselect, ppoll and io_pgetevents) in addition to the existing native and compat versions. Adding such an api reduces the logic that would need to be replicated otherwise. Signed-off-by: Deepa Dinamani <deepa.kernel@gmail.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
