After Al Viro reviewed an earlier version of this series and did a lot more of that cleanup, I decided to try to completely eliminate the rest of it and move it all into drivers. This series incorporates some of Al's work and many patches of my own, but in the end stops short of actually removing the last part, which is the scsi ioctl handlers.

2019-11-18HID: rmi: Check that the RMI_STARTED bit is set before unregistering the RMI ↵Andrew Duggan1-1/+2
transport device In the event that the RMI device is unreachable, the calls to rmi_set_mode() or rmi_set_page() will fail before registering the RMI transport device. When the device is removed, rmi_remove() will call rmi_unregister_transport_device() which will attempt to access the rmi_dev pointer which was not set. This patch adds a check of the RMI_STARTED bit before calling rmi_unregister_transport_device(). The RMI_STARTED bit is only set after rmi_register_transport_device() completes successfully.

2019-11-12HID: core: check whether Usage Page item is after Usage ID itemsCandle Sun1-6/+45
Upstream commit 58e75155009c ("HID: core: move Usage Page concatenation to Main item") adds support for Usage Page item after Usage ID items (such as keyboards manufactured by Primax). Usage Page concatenation in Main item works well for following report descriptor patterns: USAGE_PAGE (Keyboard) 05 07 USAGE_MINIMUM (Keyboard LeftControl) 19 E0 USAGE_MAXIMUM (Keyboard Right GUI) 29 E7 LOGICAL_MINIMUM (0) 15 00 LOGICAL_MAXIMUM (1) 25 01 REPORT_SIZE (1) 75 01 REPORT_COUNT (8) 95 08 INPUT (Data,Var,Abs) 81 02 ------------- USAGE_MINIMUM (Keyboard LeftControl) 19 E0 USAGE_MAXIMUM (Keyboard Right GUI) 29 E7 LOGICAL_MINIMUM (0) 15 00 LOGICAL_MAXIMUM (1) 25 01 REPORT_SIZE (1) 75 01 REPORT_COUNT (8) 95 08 USAGE_PAGE (Keyboard) 05 07 INPUT (Data,Var,Abs) 81 02 But it makes the parser act wrong for the following report descriptor pattern(such as some Gamepads): USAGE_PAGE (Button) 05 09 USAGE (Button 1) 09 01 USAGE (Button 2) 09 02 USAGE (Button 4) 09 04 USAGE (Button 5) 09 05 USAGE (Button 7) 09 07 USAGE (Button 8) 09 08 USAGE (Button 14) 09 0E USAGE (Button 15) 09 0F USAGE (Button 13) 09 0D USAGE_PAGE (Consumer Devices) 05 0C USAGE (Back) 0a 24 02 USAGE (HomePage) 0a 23 02 LOGICAL_MINIMUM (0) 15 00 LOGICAL_MAXIMUM (1) 25 01 REPORT_SIZE (1) 75 01 REPORT_COUNT (11) 95 0B INPUT (Data,Var,Abs) 81 02 With Usage Page concatenation in Main item, parser recognizes all the 11 Usages as consumer keys, it is not the HID device's real intention. This patch checks whether Usage Page is really defined after Usage ID items by comparing usage page using status. Usage Page concatenation on currently defined Usage Page will always do in local parsing when Usage ID items encountered. When Main item is parsing, concatenation will do again with last defined Usage Page if this page has not been used in the previous usages concatenation.

2019-11-06HID: wacom: generic: Treat serial number and related fields as unsignedJason Gerecke2-4/+21
The HID descriptors for most Wacom devices oddly declare the serial number and other related fields as signed integers. When these numbers are ingested by the HID subsystem, they are automatically sign-extended into 32-bit integers. We treat the fields as unsigned elsewhere in the kernel and userspace, however, so this sign-extension causes problems. In particular, the sign-extended tool ID sent to userspace as ABS_MISC does not properly match unsigned IDs used by xf86-input-wacom and libwacom. We introduce a function 'wacom_s32tou' that can undo the automatic sign extension performed by 'hid_snto32'. We call this function when processing the serial number and related fields to ensure that we are dealing with and reporting the unsigned form. We opt to use this method rather than adding a descriptor fixup in 'wacom_hid_usage_quirk' since it should be more robust in the face of future devices.

2019-11-02HID: i2c-hid: Send power-on command after resetHans de Goede1-0/+4
Before commit 67b18dfb8cfc ("HID: i2c-hid: Remove runtime power management"), any i2c-hid touchscreens would typically be runtime-suspended between the driver loading and Xorg or a Wayland compositor opening it, causing it to be resumed again. This means that before this change, we would call i2c_hid_set_power(OFF), i2c_hid_set_power(ON) before the graphical session would start listening to the touchscreen. It turns out that at least some SIS touchscreens, such as the one found on the Asus T100HA, need a power-on command after reset, otherwise they will not send any events.

2019-10-23compat_ioctl: move more drivers to compat_ptr_ioctlArnd Bergmann1-3/+1
The .ioctl and .compat_ioctl file operations have the same prototype so they can both point to the same function, which works great almost all the time when all the commands are compatible. One exception is the s390 architecture, where a compat pointer is only 31 bit wide, and converting it into a 64-bit pointer requires calling compat_ptr(). Most drivers here will never run in s390, but since we now have a generic helper for it, it's easy enough to use it consistently. I double-checked all these drivers to ensure that all ioctl arguments are used as pointers or are ignored, but are not interpreted as integer values.

2019-10-18HID: logitech-hidpp: rework device validationAndrey Smirnov1-24/+30
G920 device only advertises REPORT_ID_HIDPP_LONG and REPORT_ID_HIDPP_VERY_LONG in its HID report descriptor, so querying for REPORT_ID_HIDPP_SHORT with optional=false will always fail and prevent G920 to be recognized as a valid HID++ device. To fix this and improve some other aspects, modify hidpp_validate_device() as follows: - Inline the code of hidpp_validate_report() to simplify distingushing between non-present and invalid report descriptors - Drop the check for id >= HID_MAX_IDS || id < 0 since all of our IDs are static and known to satisfy that at compile time - Change the algorithms to check all possible report types (including very long report) and deem the device as a valid HID++ device if it supports at least one - Treat invalid report length as a hard stop for the validation algorithm, meaning that if any of the supported reports has invalid length we assume the worst and treat the device as a generic HID device. - Fold initialization of hidpp->very_long_report_length into hidpp_validate_device() since it already fetches very long report length and validates its value Fixes: fe3ee1ec007b ("HID: logitech-hidpp: allow non HID++ devices to be handled by this module") Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=204191 Reported-by: Sam Bazely <sambazley@fastmail.com> Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Cc: Jiri Kosina <jikos@kernel.org> Cc: Benjamin Tissoires <benjamin.tissoires@redhat.com> Cc: Henrik Rydberg <rydberg@bitmath.org> Cc: Pierre-Loup A.

2019-10-18HID: logitech-hidpp: split g920_get_config()Andrey Smirnov1-54/+96
Original version of g920_get_config() contained two kind of actions: 1. Device specific communication to query/set some parameters which requires active communication channel with the device, or, put in other way, for the call to be sandwiched between hid_device_io_start() and hid_device_io_stop(). 2. Input subsystem specific FF controller initialization which, in order to access a valid 'struct hid_input' via 'hid->inputs.next', requires claimed hidinput which means be executed after the call to hid_hw_start() with connect_mask containing HID_CONNECT_HIDINPUT. Location of g920_get_config() can only fulfill requirements for #1 and not #2, which might result in following backtrace: [ 88.312258] logitech-hidpp-device 0003:046D:C262.0005: HID++ 4.2 device connected.

2019-10-18HID: i2c-hid: Remove runtime power managementKai-Heng Feng1-111/+7
Runtime power management in i2c-hid brings lots of issues, such as: - When transitioning from display manager to desktop session, i2c-hid was closed and opened, so the device was set to SLEEP and ON in a short period. Vendors confirmed that their devices can't handle fast ON/SLEEP command because Windows doesn't have this behavior. - When rebooting, i2c-hid was closed, and the driver core put the device back to full power before shutdown. This behavior also triggers a quick SLEEP and ON commands that some devices can't handle, renders an unusable touchpad after reboot. - Most importantly, my power meter reports little to none energy saving when i2c-hid is runtime suspended. So let's remove runtime power management since there is no actual benefit.

2019-10-03HID: Fix assumption that devices have inputsAlan Stern14-37/+126
The syzbot fuzzer found a slab-out-of-bounds write bug in the hid-gaff driver. The problem is caused by the driver's assumption that the device must have an input report. While this will be true for all normal HID input devices, a suitably malicious device can violate the assumption. The same assumption is present in over a dozen other HID drivers. This patch fixes them by checking that the list of hid_inputs for the hid_device is nonempty before allowing it to be used.

Currently, the tablet mode switch that takes two signals as its input: base attached switch from the EC and some GMR signal from whiskers when it's folded over. This tablet mode switch is then sent to Chrome, which changes the UI. However, there are some units which have a lot of leakage on the ADC pins that the EC uses to determine whether or not a base is attached. This can result in the base being physically detached, but the EC thinking that it's still attached. The user would then be stuck in laptop mode and wouldn't be able to rotate their display. To work around this let's send "tablet mode" signal when we remove HID interface, which normally happens when we physically disconnect whiskers.

Also let's start the HID interface immediately when probing, this will ensure that we correctly process "base folded" events that may be sent as we initialize the base. Note that this requires us to add a remove() function where we stop and close the hardware and switch the LED registration away from devm interface as we need to make sure that we destroy the LED instance before we stop the hardware.
