* HID: Fix assumption that devices have inputsAlan Stern2019-10-031-3/+9
| | | | | | | | | | | | | | | | | 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.

* HID: holtekff: move MODULE_* parameters out of #ifdef blockDaniel Axtens2017-12-011-4/+4
| | | | | | | | | | | | | | | | | | If you compile with: CONFIG_HID_HOLTEK=m CONFIG_HOLTEK_FF is not set You get the following warning: WARNING: modpost: missing MODULE_LICENSE() in drivers/hid/hid-holtekff.o see include/linux/module.h for more information Fix this by moving the module info out of the #ifdef CONFIG_HOLTEK_FF block and into the un-guarded part of the file.

* HID: use hid_hw_request() instead of direct call to usbhidBenjamin Tissoires2013-02-251-3/+1
| | | | | | | | | | | | | | | | | | | This allows the hid drivers to be independent from the transport layer. The patch was constructed by replacing all occurences of usbhid_submit_report() by its hid_hw_request() counterpart. Then, drivers not requiring USB_HID anymore have their USB_HID dependency cleaned in the Kconfig file. Finally, few drivers still depends on USB_HID. Many of them are requiring the io wait callback. They are found in the next patch.

* HID: Use module_hid_driver macroH Hartley Sweeten2013-01-031-14/+1
| | | | | | | | | | | | Use the new module_hid_driver macro in all HID drivers that have a simple register/unregister init/exit. This also converts the hid drivers that test for a failure of hid_register_driver() and report the failure. Using module_hid_driver in those drivers removes the failure message.

* HID: add FF support for Holtek On Line Grip based gamepadsAnssi Hannula2011-06-271-0/+240
Add force feedback support for Holtek On Line Grip based HID devices. The protocol is more complex than that of most other rumblepads, but the device still needs to be handled as a memoryless one. Tested by Cleber de Mattos Casali with a 1241:5015 "Clone Joypad Super Power Fire" gamepad, with help from Hendrik Iben <hendrik_iben@web.de>.
