Devices speaking HID++ 2.0 report a different error code (0xff). Detect these errors too to avoid 5 second delays when the device reports an error. Caught by... well, a bug in the QEMU emulation of this receiver. Renamed fap to rap for HID++ 1.0 errors because it is more logical, it has no functional difference.

Current names are reported as "K750", "M705", and it can be misleading for the users when they look at their input device list. Prefixing the names with "Logitech " makes things better.

If wtp_connect() fails, that means most of the time that the device has been disconnected. Subsequent attempts to contact the device will fail too, so it's simpler to bail out earlier.

Previously wtp_raw_event would be called through hidpp_raw_hidpp_event (for the touchpad report) and hidpp_raw_event (for the mouse report). This patch removes one calling surface, making a clearer distinction between "generic HID++ processing" (matching internal reports) and device-specific event processing.

If a touchpad reports the F11 data40 register then this indicates that the touchpad reports additional ACM (Accidental Contact Mitigation) data after the F11 data in the HID attention report. These additional bytes shift the position of the F30 button data causing the driver to incorrectly report button state when this functionality is present.

Before ->start() is called, bufsize size is set to HID_MIN_BUFFER_SIZE, 64 bytes. While processing the IRQ, we were asking to receive up to wMaxInputLength bytes, which can be bigger than 64 bytes. Later, when ->start is run, a proper bufsize will be calculated. Given wMaxInputLength is said to be unreliable in other part of the code, set to receive only what we can even if it results in truncated reports.

Pull workqueue update from Tejun Heo: "Work items which may be involved in memory reclaim path may be executed by the rescuer under memory pressure. When a rescuer gets activated, it processes whatever are on the pending list and then goes back to sleep until the manager kicks it again which involves 100ms delay. This is problematic for self-requeueing work items or the ones running on ordered workqueues as there always is only one work item on the pending list when the rescuer kicks in. The execution of that work item produces more to execute but the rescuer won't see them until after the said 100ms has passed, so such workqueues would only execute one work item every 100ms under prolonged memory pressure, which BTW may be being prolonged due to the slow execution. Neil wrote up a patch which fixes this issue by keeping the rescuer working as long as the target workqueue is busy but doesn't have enough workers" * 'for-3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: workqueue: allow rescuer thread to do more work. workqueue: invert the order between pool->lock and wq_mayday_lock workqueue: cosmetic update in rescuer_thread()

Balance a hid_device_io_start() call with hid_device_io_stop() in the error path. This avoids processing of HID reports when the probe fails which possibly leads to invalid memory access in hid_device_probe() as report_enum->report_id_hash might already be freed via hid_close_report(). hid_set_drvdata() is called before wtp_allocate, be consistent and clear drvdata too on the error path of wtp_allocate.

The existing generic touch code only reports events after reading an entire HID report, which practically means that only data about the last contact in a report will ever be provided to userspace. This patch uses a trick from hid-multitouch.c to discover what type of field is at the end of each contact; when such a field is encountered all the stored contact data will be reported.

Pull sound updates from Takashi Iwai: "This became a fairly large pull request. In addition to the usual driver updates / fixes, there have been a high amount of cleanups in ASoC area, as well as control API helpers and kernel documentations fixes touching through the whole tree. In the driver side, the biggest changes are the support for new Intel SoC found on new x86 machines, and the updates of FireWire dice and oxfw drivers. Some remarkable items are below: ALSA core: - PCM mmap code cleanup, removal of arch-dependent codes - PCM xrun injection support - PCM hwptr tracepoint support - Refactoring of snd_pcm_action(), simplification of PCM locking - Robustified sequecner auto-load functionality - New control API helpers and lots of cleanups along with them - Lots of kerneldoc fixes and cleanups USB-audio: - The mixer resume code was largely rewritten, and the devices with quirks are resumed properly. - New hardware support: Focusrite Scarlett, Digidesign Mbox1, Denon/Marantz DACs, Zoom R16/24 FireWire: - DICE driver updates with better duplex and sync support, including MIDI support - New OXFW driver for Oxford Semiconductor FW970/971 chipset, including the previous LaCie Speakers device. Fullduplex and MIDI support included as well as DICE driver.

Pull devicetree changes from Grant Likely: "Lots of activity in the devicetree code for v3.18. Most of it is related to getting all of the overlay support code in place, but there are other important things in there. Highlights: - OF_RECONFIG notifiers for SPI, I2C and Platform devices. Those subsystems can now respond to live changes to the device tree. - CONFIG_OF_OVERLAY method for applying live changes to the device tree - Removal of the of_allnodes list. This used to be used to iterate over all the nodes in the device tree, but it is unnecessary because the same thing can be done by iterating over the list of child pointers. Getting rid of of_allnodes saves some memory and avoids the possibility of of_allnodes being sorted differently from the child lists. - Support for retrieving original DTB blob via sysfs.

Currently, when trying to reuse a socket, vxlan_sock_add will grab vn->sock_lock, locate a reusable socket, inc refcount and release vn->sock_lock. But vxlan_sock_release() will first decrement refcount, and then grab that lock. refcnt operations are atomic but as currently we have deferred works which hold vs->refcnt each, this might happen, leading to a use after free (specially after vxlan_igmp_leave): CPU 1 CPU 2 deferred work vxlan_sock_add ... ... spin_lock(&vn->sock_lock) vs = vxlan_find_sock(); vxlan_sock_release dec vs->refcnt, reaches 0 spin_lock(&vn->sock_lock) vxlan_sock_hold(vs), refcnt=1 spin_unlock(&vn->sock_lock) hlist_del_rcu(&vs->hlist); vxlan_notify_del_rx_port(vs) spin_unlock(&vn->sock_lock) So when we look for a reusable socket, we check if it wasn't freed already before reusing it.

Or Gerlitz says: ==================== mlx4 driver update This series from Matan, Jenny, Dotan and myself is mostly about adding support to a new performance optimized flow steering mode (patches 4-10). The 1st two patches are small fixes (one for VXLAN and one for SRIOV), and the third patch is a fix to avoid hard-lockup situation when many (hunderds) processes holding user-space QPs/CQs get events.

Add the required firmware commands for A0 steering and a way to enable that. The firmware support focuses on INIT_HCA, QUERY_HCA, QUERY_PORT, QUERY_DEV_CAP and QUERY_FUNC_CAP commands. Those commands are used to configure and query the device. The different A0 DMFS (steering) modes are: Static - optimized performance, but flow steering rules are limited. This mode should be choosed explicitly by the user in order to be used. Dynamic - this mode should be explicitly choosed by the user. In this mode, the FW works in optimized steering mode as long as it can and afterwards automatically drops to classic (full) DMFS. Disable - this mode should be explicitly choosed by the user. The user instructs the system not to use optimized steering, even if the FW supports Dynamic A0 DMFS (and thus will be able to use optimized steering in Default A0 DMFS mode). Default - this mode is implicitly choosed. In this mode, if the FW supports Dynamic A0 DMFS, it'll work in this mode. Otherwise, it'll work at Disable A0 DMFS mode. Under SRIOV configuration, when the A0 steering mode is enabled, older guest VF drivers who aren't using the RX QP allocation flag (MLX4_RESERVE_A0_QP) will get a QP from the general range and fail when attempting to register a steering rule. To avoid that, the PF context behaviour is changed once on A0 static mode, to require support for the allocation flag in VF drivers too. In order to enable A0 steering, we use log_num_mgm_entry_size param. If the value of the parameter is not positive, we treat the absolute value of log_num_mgm_entry_size as a bit field. Setting bit 2 of this bit field enables static A0 steering. Signed-off-by: Matan Barak <matanb@mellanox.com> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: David S.
