2020-09-01HID: core: Sanitize event code and type when mapping inputMarc Zyngier2-0/+6
When calling into hid_map_usage(), the passed event code is blindly stored as is, even if it doesn't fit in the associated bitmap. This event code can come from a variety of sources, including devices masquerading as input devices, only a bit more "programmable". Instead of taking the event code at face value, check that it actually fits the corresponding bitmap, and if it doesn't: - spit out a warning so that we know which device is acting up - NULLify the bitmap pointer so that we catch unexpected uses Code paths that can make use of untrusted inputs can now check that the mapping was indeed correct and bail out if not.

2020-09-01HID: core: Correctly handle ReportSize being zeroMarc Zyngier1-2/+13
It appears that a ReportSize value of zero is legal, even if a bit non-sensical. Most of the HID code seems to handle that gracefully, except when computing the total size in bytes. When fed as input to memset, this leads to some funky outcomes. Detect the corner case and correctly compute the size.

When operating in XInput mode, the 8bitdo SN30 Pro+ requires the same quirk as the official Xbox One Bluetooth controllers for rumble to function. Other controllers like the N30 Pro 2, SF30 Pro, SN30 Pro, etc. probably also need this quirk, but I do not have the hardware to test.

2020-08-31HID: quirks: Set INCREMENT_USAGE_ON_DUPLICATE for all Saitek X52 devicesNirenjan Krishnan2-0/+4
The Saitek X52 family of joysticks has a pair of axes that were originally (by the Windows driver) used as mouse pointer controls. The corresponding usage page is the Game Controls page, which is not recognized by the generic HID driver, and therefore, both axes get mapped to ABS_MISC. The quirk makes the second axis get mapped to ABS_MISC+1, and therefore made available separately. One Saitek X52 device is already fixed. This patch fixes the other two known devices with VID/PID 06a3:0255 and 06a3:0762. Signed-off-by: Nirenjan Krishnan <nirenjan@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2020-08-18Revert "HID: usbhid: do not sleep when opening device"Jiri Kosina2-31/+24
This reverts commit d3132792285859253c466354fd8d54d1fe0ba786. This patch causes a regression with quite a few devices, as probing fails because of the race where the first IRQ is dropped on the floor (after hid_device_io_start() happens, but before the 50ms timeout passess), and report descriptor never gets parsed and populated. As this is just a boot time micro-optimization, let's revert the patch for 5.9 now, and fix this properly eventually for next merge window.

2020-08-17HID: i2c-hid: Always sleep 60ms after I2C_HID_PWR_ON commandsHans de Goede1-9/+13
Before this commit i2c_hid_parse() consists of the following steps: 1. Send power on cmd 2. usleep_range(1000, 5000) 3. Send reset cmd 4. Wait for reset to complete (device interrupt, or msleep(100)) 5. Send power on cmd 6. Try to read HID descriptor Notice how there is an usleep_range(1000, 5000) after the first power-on command, but not after the second power-on command. Testing has shown that at least on the BMAX Y13 laptop's i2c-hid touchpad, not having a delay after the second power-on command causes the HID descriptor to read as all zeros. In case we hit this on other devices too, the descriptor being all zeros can be recognized by the following message being logged many, many times: hid-generic 0018:0911:5288.0002: unknown main item tag 0x0 At the same time as the BMAX Y13's touchpad issue was debugged, Kai-Heng was working on debugging some issues with Goodix i2c-hid touchpads. It turns out that these need a delay after a PWR_ON command too, otherwise they stop working after a suspend/resume cycle. According to Goodix a delay of minimal 60ms is needed. Having multiple cases where we need a delay after sending the power-on command, seems to indicate that we should always sleep after the power-on command. This commit fixes the mentioned issues by moving the existing 1ms sleep to the i2c_hid_set_power() function and changing it to a 60ms sleep.

2020-07-14HID: input: Fix devices that return multiple bytes in battery reportGrant Likely1-3/+3
Some devices, particularly the 3DConnexion Spacemouse wireless 3D controllers, return more than just the battery capacity in the battery report. The Spacemouse devices return an additional byte with a device specific field. However, hidinput_query_battery_capacity() only requests a 2 byte transfer. When a spacemouse is connected via USB (direct wire, no wireless dongle) and it returns a 3 byte report instead of the assumed 2 byte battery report the larger transfer confuses and frightens the USB subsystem which chooses to ignore the transfer. Then after 2 seconds assume the device has stopped responding and reset it. This can be reproduced easily by using a wired connection with a wireless spacemouse. The Spacemouse will enter a loop of resetting every 2 seconds which can be observed in dmesg. This patch solves the problem by increasing the transfer request to 4 bytes instead of 2. The fix isn't particularly elegant, but it is simple and safe to backport to stable kernels. A further patch will follow to more elegantly handle battery reports that contain additional data.

The Ultrabook Keyboard sends a spurious F23 key-press when resuming from suspend. GNOME uses F23 to toggle the touchpad on/off so this causes the OSD graphics for the touchpad toggle to show on resume.

2020-06-24HID: apple: Disable Fn-key key-re-mapping on clone keyboardsHans de Goede1-0/+18
The Maxxter KB-BT-001 Bluetooth keyboard, which looks somewhat like the Apple Wireless Keyboard, is using the vendor and product IDs (05AC:0239) of the Apple Wireless Keyboard (2009 ANSI version) <sigh>. But its F1 - F10 keys are marked as sending F1 - F10, not the special functions hid-apple.c maps them too; and since its descriptors do not contain the HID_UP_CUSTOM | 0x0003 usage apple-hid looks for for the Fn-key, apple_setup_input() never gets called, so F1 - F6 are mapped to key-codes which have not been set in the keybit array causing them to not send any events at all. The lack of a usage code matching the Fn key in the clone is actually useful as this allows solving this problem in a generic way. This commits adds a fn_found flag and it adds a input_configured callback which checks if this flag is set once all usages have been mapped. If it is not set, then assume this is a clone and clear the quirks bitmap so that the hid-apple code does not add any special handling to this keyboard. This fixes F1 - F6 not sending anything at all and F7 - F12 sending the wrong codes on the Maxxter KB-BT-001 Bluetooth keyboard and on similar clones.

2020-06-19HID: Wiimote: Treat the d-pad as an analogue stickDaniel G. Morse3-24/+50
The controllers from the Super Nintendo Classic Edition (AKA the SNES Mini) appear as a Classic Controller Pro when connected to a Wii Remote. All the buttons work as the same, with the d-pad being mapped the same as the d-pad on the Classic Controller Pro. This differs from the behaviour of most controllers with d-pads and no analogue sticks, where the d-pad maps to ABS_HAT1X for left and right, and ABS_HAT1Y for up and down. This patch adds an option to the hid-wiimote module to make the Super Nintendo Classic Controller behave this way. The patch has been tested with a Super Nintendo Classic Controller plugged into a Wii Remote in both with the option both enabled and disabled. When enabled the d-pad acts as the analogue control, and when disabled it acts as it did before the patch was applied. This patch has not been tested with e Wii Classic Controller (either the original or the pro version) as I do not have one of these controllers. Although I have not tested it with these controllers, I think it is likely this patch will also work with the NES Classic Edition Controllers. Signed-off-by: Daniel G.

2020-06-16HID: input: do not run GET_REPORT unless there's a Resolution MultiplierPeter Hutterer1-10/+20
hid-multitouch currently runs GET_REPORT for Contact Max and again to retrieve the Win8 blob. If both are within the same report, the Resolution Multiplier code calls GET_FEATURE again and this time, possibly due to timing, it causes the ILITEK-TP device interpret the GET_FEATURE as an instruction to change the mode and effectively stop the device from functioning as expected. Notably: the device doesn't even have a Resolution Multiplier so it shouldn't be affected by any of this at all. Fix this by making sure we only execute GET_REPORT if there is a Resolution Multiplier in the respective report. Where the HID_QUIRK_NO_INIT_REPORTS field is set we just bail out immediately. This shouldn't be triggered by any real device anyway. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Tested-by: Wen He <wen.he_1@nxp.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

The Mediacom FlexBook edge13 uses the SIPODEV SP1064 touchpad, which does not supply descriptors, so it has to be added to the override list. Signed-off-by: Federico Ricchiuto <fed.ricchiuto@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2020-06-16HID: usbhid: do not sleep when opening deviceDmitry Torokhov2-24/+31
usbhid tries to give the device 50 milliseconds to drain its queues when opening the device, but does it naively by simply sleeping in open handler, which slows down device probing (and thus may affect overall boot time). However we do not need to sleep as we can instead mark a point of time in the future when we should start processing the events.

2020-06-13treewide: replace '---help---' in Kconfig files with 'help'Masahiro Yamada3-108/+108
Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

After commit c23e2043d5f7 ("HID: multitouch: do not filter mice nodes"), MT_CLS_WIN_8 also supports mouse nodes, hence make MT_CLS_WIN_8_DUAL redundant. Remove MT_CLS_WIN_8_DUAL accordingly.

2020-05-27HID: multitouch: enable multi-input as a quirk for some devicesBenjamin Tissoires1-0/+26
Two touchpad/trackstick combos are currently not behaving properly. They define a mouse emulation collection, as per Win8 requirements, but also define a separate mouse collection for the trackstick. The way the kernel currently treat the collections is that it merges both in one device. However, given that the first mouse collection already defines X,Y and left, right buttons, when mapping the events from the second mouse collection, hid-multitouch sees that these events are already mapped, and simply ignores them. To be able to report events from the tracktick, add a new quirked class for it, and manually add the 2 devices we know about.
