  • d9d4b1e46   HID: Fix assumption that devices have inputs ... Browse Code »

    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.

  • d88142725   HID: use hid_hw_request() instead of direct call to usbhid ... Browse Code »

    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.

  • f425458ea   HID: Use module_hid_driver macro ... Browse Code »

    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.

  • b55ebc27b   HID: ACRUX - handle gamepads with different report layout ... Browse Code »

    There are gamepads that share the same VID and PID but have different
    report structure - instead of having 4 fields with one value they have
    one field that can hold all 4 values. Make the driver cope with devices
    using both styles.

  • 0ae438109   HID: ACRUX - activate the device immediately after binding ... Browse Code »

    This device does not tolerate delayed opening and goes into a coma if
    we try to that. Ubuntu even has a crutch for udev that opened the device
    upon seeing it for the first time, but it did not work if we happened to
    boot with the device attached, since by the time userspace got around
    opening the device it was too late. Let's start the device immediately
    to deal with this issue.

  • 4291ee305   HID: Add and use hid_<level>: dev_<level> equivalents ... Browse Code »

    Neaten current uses of dev_ by adding and using
    hid specific hid_ macros.

    Convert existing uses of dev_ uses to hid_.
    Convert hid-pidff printk uses to hid_.

    Remove err_hid and use hid_err instead.

    Add missing newlines to logging messages where necessary.
    Coalesce format strings.

    Add and use pr_fmt(fmt) KBUILD_MODNAME ": " fmt

    Other miscellaneous changes:

    Add const struct hid_device * argument to hid-core functions
    extract() and implement() so hid_ can be used by them.
    Fix bad indentation in hid-core hid_input_field function
    that calls extract() function above.
