Getting a report (e.g. feature report) from a device requires us to send a request indicating which report we want to retrieve and then waiting for the corresponding response containing that report. We already provide the response structure to the request call, but the request isn't marked as a request that expects a response. Thus the request returns before we receive the response and the response buffer indicates a zero length response due to that. This essentially means that the get-report calls are broken and will always indicate that a report of length zero has been read. Fix this by appropriately marking the request.

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. Signed-off-by:

There is no need to use a quirk and then return -ENODEV from the asus_probe() function to avoid that hid-asus binds to the hiddev for the USB-interface for the hid-multitouch touchpad. The hid-multitouch hiddev has a group of HID_GROUP_MULTITOUCH_WIN_8, so the same result can be achieved by making the hid_device_id entry for the dock in the asus_devices[] table only match on HID_GROUP_GENERIC instead of having it match HID_GROUP_ANY.

Commit 9d7b1866 ("HID: magicmouse: add support for Apple Magic Trackpad 2") added a sanity check for an Apple trackpad but returned success instead of -ENODEV when the check failed. This means that the remove callback will dereference the never-initialised driver data pointer when the driver is later unbound (e.g. on USB disconnect).

When the Apple Magic Trackpad 2 is connected over USB it registers four hid_device report descriptors, however, the driver only handles the one with type HID_TYPE_USBMOUSE and ignores the other three, thus, no driver data is attached to them. When the device is disconnected, the remove callback is called for the four hid_device report descriptors, crashing when the driver data is NULL. Check that the driver data is not NULL before using it in the remove callback. Signed-off-by:

For ELAN touchscreen, we found our boot code of IC was not flexible enough to receive and handle this command. Once the FW main code of our controller is crashed for some reason, the controller could not be enumerated successfully to be recognized by the system host. therefore, it lost touch functionality. Add quirk for skip send power-on command after reset. It will impact to ELAN touchscreen and touchpad on HID over I2C projects. Fixes: 43b7029f ("HID: i2c-hid: Send power-on command after reset").

In hid_submit_ctrl(), the way of calculating the report length doesn't take into account that report->size can be zero. When running the syzkaller reproducer, a report of size 0 causes hid_submit_ctrl) to calculate transfer_buffer_length as 16384. When this urb is passed to the usb core layer, KMSAN reports an info leak of 16384 bytes. To fix this, first modify hid_report_len() to account for the zero report size case by using DIV_ROUND_UP for the division. Then, call it from hid_submit_ctrl().

Just like the K12A the Dell K15A keyboard-dock has problems with get_feature requests. This sometimes leads to several "failed to fetch feature 8" messages getting logged, after which the touchpad may or may not work. Just like the K15A these errors are triggered by undocking and docking the tablet. There also seem to be other problems when undocking and then docking again in quick succession. It seems that in this case the keyboard-controller still retains some power from capacitors and does not go through a power-on-reset leaving it in a confuses state, symptoms of this are: 1. The USB-ids changing to 048d:8910 2. Failure to read the HID descriptors on the second (mouse) USB intf. 3. The touchpad freezing after a while These problems can all be cleared by undocking the keyboard and waiting a full minute before redocking it. Unfortunately there is nothing we can do about this in the kernel. Signed-off-by:

A number of USB keyboards, using the Semitek firmware, are capable of handling arbitrary N-key rollover, but due to a buggy report descriptor, keys beyond the sixth cannot be detected by the generic HID driver. There are numerous hardware variants sold by several vendors, mostly using generic names like "GK61" for the 61-key version. These keyboards are sometimes known collectively as the "GK6X" series. The keyboard has three USB interfaces. Interface 0 uses the standard HID boot protocol, limited to eight modifier keys and six normal keys; interface 2 uses a custom report format that permits any number of keys. If more than six keys are pressed simultaneously, the first six are reported via interface 0 while subsequent keys are reported via interface 2. (Interface 1 uses a custom protocol for reprogramming the keyboard; this can be controlled through userspace tools and is not of concern for the present driver.) The report descriptor for interface 2, however, is incorrect (for report ID 0x04, the input field is marked as "array" rather than "variable".) The descriptor appears to be correct in other respects, so we simply replace the incorrect byte before parsing the descriptor. Signed-off-by:
