2021-12-02HID: sony: fix error path in probeBenjamin Tissoires
When the setup of the GHL fails, we are not calling hid_hw_stop(). This leads to the hidraw node not being released, meaning a crash whenever somebody attempts to open the file.

2021-12-02HID: check for valid USB device for many HID driversGreg Kroah-Hartman
Many HID drivers assume that the HID device assigned to them is a USB device as that was the only way HID devices used to be able to be created in Linux. However, with the additional ways that HID devices can be created for many different bus types, that is no longer true, so properly check that we have a USB device associated with the HID device before allowing a driver that makes this assumption to claim it.

2021-06-15HID: sony: fix freeze when inserting ghlive ps3/wii donglesPascal Giard
This commit fixes a freeze on insertion of a Guitar Hero Live PS3/WiiU USB dongle. Indeed, with the current implementation, inserting one of those USB dongles will lead to a hard freeze. I apologize for not catching this earlier, it didn't occur on my old laptop. While the issue was isolated to memory alloc/free, I could not figure out why it causes a freeze. So this patch fixes this issue by simplifying memory allocation and usage. We remind that for the dongle to work properly, a control URB needs to be sent periodically. We used to alloc/free the URB each time this URB needed to be sent. With this patch, the memory for the URB is allocated on the probe, reused for as long as the dongle is plugged in, and freed once the dongle is unplugged.

2020-11-25HID: sony: Workaround for DS4 dongle hotplug kernel crash.Roderick Colenbrander
The hid-sony driver has custom DS4 connect/disconnect logic for the DS4 dongle, which is a USB dongle acting as a proxy to Bluetooth connected DS4. The connect/disconnect logic works fine generally, however not in conjunction with Steam. Steam implements its own DS4 driver using hidraw. Both hid-sony and Steam are issuing their own HID requests and are racing each other during DS4 dongle connect/disconnect resulting in a kernel crash in hid-sony. The problem is that upon a DS4 connect to the dongle, hid-sony kicks of 'ds4_get_calibration_data' from within its dongle hotplug code. The calibration code issues raw HID feature report for reportID 0x02. When Steam is running, it issues a feature report for reportID 0x12 typically just prior to hid-sony requesting feature reportID 0x02. The result is that 'ds4_get_calibration_data' receives the data Steam requested as that's the HID report returing first. Currently this results in it processing invalid data, which ultimately results in a divide by zero upon a future 'dualshock4_parse_report'. The solution for now is to check within 'ds4_get_calibration_data' to check if we received data for the feature report we issued and if not retry. This fixes bug 206785.

2020-11-25HID: sony: Report more accurate DS4 power status.Roderick Colenbrander
This patch moves the power supply status logic to DS3/DS4 parse_report, to allow for more accurate DS4 status reporting. The DS4 power status code was actually incorrect, but reported okay'ish data in most cases. There was a different interpretation of the battery_info values 0-10 or 0-9 depending on cable state. It added +1 to extend the range to 0-10. This is actually incorrect, there is no different range. Values higher than 11 actually indicates 'full' and 14/15 'error' for which we reported 100% and a valid power state. Moving the status logic to parse_report avoids having to pass more state to the generic sony_battery_get_property and simplifies the code.

2020-05-26HID: sony: Fix for broken buttons on DS3 USB donglesScott Shumate
Fix for non-working buttons on knock-off USB dongles for Sony controllers. These USB dongles are used to connect older Sony DA/DS1/DS2 controllers via USB and are common on Amazon, AliExpress, etc. Without the patch, the square, X, and circle buttons do not function. These dongles used to work prior to kernel 4.10 but removing the global DS3 report fixup in commit e19a267b9987 ("HID: sony: DS3 comply to Linux gamepad spec") exposed the problem. Many people reported the problem on the Ubuntu forums and are working around the problem by falling back to the 4.9 hid-sony driver. The problem stems from these dongles incorrectly reporting their button count as 13 instead of 16. This patch fixes up the report descriptor by changing the button report count to 16 and removing 3 padding bits.

2019-10-03HID: Fix assumption that devices have inputsAlan Stern
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.

2019-08-06HID: sony: Fix race condition between rumble and device remove.Roderick Colenbrander
Valve reported a kernel crash on Ubuntu 18.04 when disconnecting a DS4 gamepad while rumble is enabled. This issue is reproducible with a frequency of 1 in 3 times in the game Borderlands 2 when using an automatic weapon, which triggers many rumble operations. We found the issue to be a race condition between sony_remove and the final device destruction by the HID / input system. The problem was that sony_remove didn't clean some of its work_item state in "struct sony_sc". After sony_remove work, the corresponding evdev node was around for sufficient time for applications to still queue rumble work after "sony_remove". On pre-4.19 kernels the race condition caused a kernel crash due to a NULL-pointer dereference as "sc->output_report_dmabuf" got freed during sony_remove. On newer kernels this crash doesn't happen due the buffer now being allocated using devm_kzalloc. However we can still queue work, while the driver is an undefined state. This patch fixes the described problem, by guarding the work_item "state_worker" with an initialized variable, which we are setting back to 0 on cleanup.

Known limitations - The built-in accelerometers are not supported by these changes - When the Drag (Fn) key is used as a mouse button, the button is automatically released when the key begins repeating.

2017-03-21HID: sony: Remove report descriptor fixup for DS4Roderick Colenbrander
The DS4 in BT mode sends initial input reports through report 1, which is described in the HID report descriptors. When activated after sending a certain feature report, the device uses report 17. Currently the hid-sony driver fixes up the BT HID report descriptors, so the HID layer can manage input reports for report 17. We think it is best to eliminate this fixup and do the handling ourselves, which is what this patch does. The main motivation is that there are various users of DS4 through hidraw, including various cross-platform applications/games, which have their own HID parsing across Linux/Win/OSX. Due to the fixup the descriptors differ, which is causing pain for many developers including major game publishers (who reached out privately). Without the fixup, the Windows titles also have a fighting chance for working on Wine, which provides HID support now. Overall it felt best because of these reasons to remove the fixup.

2017-03-21HID: sony: Calibrate DS4 motion sensorsRoderick Colenbrander
The DS4 motion sensors require calibration for accurate operation. This patch adds calibration for both the accelerometer and the gyroscope. Calibration requires reading device specific scaling factors and offsets. For precision reasons we store these values as a numerator and denominator and apply the values when processing the data.

2017-03-21HID: sony: Report DS4 motion sensors through a separate deviceRoderick Colenbrander
The DS4 motion sensors are currently mapped by the hid-core driver to non-existing axes in between ABS_MISC and ABS_MT_SLOT, because the device already exhausted ABS_X-ABS_RZ. For a part the mapping by hid-core is accomplished by a fixup in hid-sony as the motion axes actually use vendor specific usage pages. This patch makes the DS4 use a separate input device for the motion sensors and reports acceleration data through ABS_X-ABS_Z and gyroscope data through ABS_RX-ABS_RZ. In addition it extends the event spec to allow gyroscope data through ABS_RX-ABS_RZ when INPUT_PROP_ACCELEROMETER is set. This change was suggested by Peter Hutterer during a discussion on linux-input.

2017-03-06HID: sony: Fix input device leak when connecting a DS4 twice using USB/BTRoderick Colenbrander
When a user connects a DS4 twice using USB and BT, we reject the second device connection after the setup work. We then perform a cleanup, but during cleanup we are not removing the touchpad device. This leads to leakage of an input device, which we would never remove. It can likely result into a kernel oops as well when the touchpad evdev node is accessed and the underlaying HID device has been removed from the system.
