Refactor and extract UC-Logic tablet initialization and parameter discovery into a module.

2019-02-15HID: intel-ish-hid: Optimize writing ipc message from queueHong Liu2-18/+3
Currently we are using one additional static variable and a spinlock to prevent contention of writing IPC messages to ISH hardware, which is not necessary. Once ISH is ready to accept new data, we can push new data to hardware. This pushing of new data is already protected by wr_processing_spinlock for contention, which is enough. So use this spinlock to check both readiness for accepting new data and once ready allow writing of ipc message from queue to ISH hardware. While here, cleaned up some space after return.

2019-02-15HID: intel-ish-hid: avoid binding wrong ishtp_cl_deviceHong Liu1-1/+3
When performing a warm reset in ishtp bus driver, the ishtp_cl_device will not be removed, its fw_client still points to the already freed ishtp_device.fw_clients array. Later after driver finishing ishtp client enumeration, this dangling pointer may cause driver to bind the wrong ishtp_cl_device to the new client, causing wrong callback to be called for messages intended for the new client. This helps in development of firmware where frequent switching of firmwares is required without Linux reboot.

There is a new firmware for the Steam Controller with support for BLE connections. When using such a device with a wired connection, it reboots itself every 10 seconds unless an application has opened it.

2019-02-07HID: Add support for Toshiba WT10A tablet bluetooth keyboardHans de Goede2-0/+4
The bluetooth-keyboard which comes with the Toshiba WT10A tablet uses a couple of usage codes in the vendor specific ffbc page. The keyboard has a vendor-id of 04f2 which maps to Chicony. Other then adding a few keymappings for the ffbc usages, no special handling is necessary. So rather then adding a new hid-toshiba driver, this commit adds the ID and 2 extra key-mappings to the hid-topseed driver. The hid-topseed driver already contains mapping for some ffbc usages (and does nothing else) and it already binds to another Chicony manufactured keyboard.

2019-02-01HID: intel-ish-hid: Use VID/PID from ISHSrinivas Pandruvada1-2/+2
The Intel ISH HID can now have other devices attached to it, not just sensors. Hence ISH HID transport is no longer just used for sensors. Currently the vendor and product id is hardcoded for sensors, but they can be obtained from ISH firmware for the real device. The driver already extract them and store as part of device_info structure in client_data. So use vendor id/product id obtained from the ISH firmware.

2019-01-29HID: debug: fix the ring buffer implementationVladis Dronov1-73/+47
Ring buffer implementation in hid_debug_event() and hid_debug_events_read() is strange allowing lost or corrupted data. After commit 717adfdaf147 ("HID: debug: check length before copy_to_user()") it is possible to enter an infinite loop in hid_debug_events_read() by providing 0 as count, this locks up a system. Fix this by rewriting the ring buffer implementation with kfifo and simplify the code. This fixes CVE-2019-3819. v2: fix an execution logic and add a comment v3: use __set_current_state() instead of set_current_state() Link: https://bugzilla.redhat.com/show_bug.cgi?id=1669187 Cc: stable@vger.kernel.org # v4.18+ Fixes: cd667ce24796 ("HID: use debugfs for events/reports dumping") Fixes: 717adfdaf147 ("HID: debug: check length before copy_to_user()") Signed-off-by: Vladis Dronov <vdronov@redhat.com> Reviewed-by: Oleg Nesterov <oleg@redhat.com> Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com>
2019-01-29HID: wacom: Move HID fix for AES serial number into wacom_hid_usage_quirkJason Gerecke2-21/+32
The 'wacom_hid_usage_quirk' function is the intended home for fixing up descriptors that are buggy or that don't quite fit the mold. Commit 578325120e was supposed to move all of these quirks but it missed the code to handle fixup the serial number usages for AES pens. Lets move this code out of 'wacom_wac_pen_usage_mapping' where it was previously lurking and put it into the same place as the others.
