2019-08-06Input: applespi - use struct_size() helperGustavo A. R. Silva
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct touchpad_protocol { ... struct tp_finger fingers[0]; }; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(*tp) + tp->number_of_fingers * sizeof(tp->fingers[0]); with: struct_size(tp, fingers, tp->number_of_fingers) This code was detected with the help of Coccinelle.

2019-07-23Input: elantech - enable SMBus on new (2018+) systemsKai-Heng Feng
There are some new HP laptops with Elantech touchpad that don't support multitouch. Currently we use ETP_NEW_IC_SMBUS_HOST_NOTIFY() to check if SMBus is supported, but in addition to firmware version, the bus type also informs us whether the IC can support SMBus. To avoid breaking old ICs, we will only enable SMbus support based the bus type on systems manufactured after 2018. Lastly, let's consolidate all checks into elantech_use_host_notify() and use it to determine whether to use PS/2 or SMBus.

In the function alps_is_cs19_trackpoint(), we check if the param[1] is in the 0x20~0x2f range, but the code we wrote for this checking is not correct: (param[1] & 0x20) does not mean param[1] is in the range of 0x20~0x2f, it also means the param[1] is in the range of 0x30~0x3f, 0x60~0x6f...

2019-07-19Input: add Apple SPI keyboard and trackpad driverRonald Tschalär
The keyboard and trackpad on recent MacBook's (since 8,1) and MacBookPro's (13,* and 14,*) are attached to an SPI controller instead of USB, as previously. The higher level protocol is not publicly documented and hence has been reverse engineered. As a consequence there are still a number of unknown fields and commands. However, the known parts have been working well and received extensive testing and use. In order for this driver to work, the proper SPI drivers need to be loaded too; for MB8,1 these are spi_pxa2xx_platform and spi_pxa2xx_pci; for all others they are spi_pxa2xx_platform and intel_lpss_pci.

2019-07-15Input: alps - don't handle ALPS cs19 trackpoint-only deviceHui Wang
On a latest Lenovo laptop, the trackpoint and 3 buttons below it don't work at all, when we move the trackpoint or press those 3 buttons, the kernel will print out: "Rejected trackstick packet from non DualPoint device" This device is identified as an alps touchpad but the packet has trackpoint format, so the alps.c drops the packet and prints out the message above. According to XiaoXiao's explanation, this device is named cs19 and is trackpoint-only device, its firmware is only for trackpoint, it is independent of touchpad and is a device completely different from DualPoint ones. To drive this device with mininal changes to the existing driver, we just let the alps driver not handle this device, then the trackpoint.c will be the driver of this device if the trackpoint driver is enabled. (if not, this device will fallback to a bare PS/2 device) With the trackpoint.c, this trackpoint and 3 buttons all work well, they have all features that the trackpoint should have, like scrolling-screen, drag-and-drop and frame-selection.

Pull stream_open() updates from Kirill Smelkov: "This time on stream_open front it is only two small changes: - the first one converts stream_open.cocci to treat all functions that start with wait_.* as blocking. Previously it was only wait_event_.* functions that were considered as blocking, but this was falsely reporting several deadlock cases as only warning. This was picked by linux-kbuild and entered mainline as commit 0c4ab18fc33b ("coccinelle: api/stream_open: treat all wait_.*() calls as blocking"), and already merged earlier. - the second one teaches stream_open.cocci to consider files as being stream-like even if they use noop_llseek. It results in two more drivers being converted to stream_open() (mousedev.c and hid-sensor-custom.c)" * tag 'stream_open-5.3' of https://lab.nexedi.com/kirr/linux: *: convert stream-like files -> stream_open, even if they use noop_llseek
2019-07-14*: convert stream-like files -> stream_open, even if they use noop_llseekKirill Smelkov
This patch continues 10dce8af3422 (fs: stream_open - opener for stream-like files so that read and write can run simultaneously without deadlock) and c5bf68fe0c86 (*: convert stream-like files from nonseekable_open -> stream_open) and teaches steam_open.cocci to consider files as being stream-like not only if they have .llseek=no_llseek, but also if they have .llseek=noop_llseek. This is safe to do: the comment about noop_llseek says This is an implementation of ->llseek useable for the rare special case when userspace expects the seek to succeed but the (device) file is actually not able to perform the seek. In this case you use noop_llseek() instead of falling back to the default implementation of ->llseek. and in general noop_llseek was massively added to drivers in 6038f373a3dc (llseek: automatically add .llseek fop) when changing default for NULL .llseek from NOP to no_llseek with the idea to avoid breaking compatibility, if maybe some user-space program was using lseek on a device without caring about the result, but caring if it was an error or not. Amended semantic patch produces two changes when applied tree-wide: drivers/hid/hid-sensor-custom.c:690:8-24: WARNING: hid_sensor_custom_fops: .read() has stream semantic; safe to change nonseekable_open -> stream_open. drivers/input/mousedev.c:564:1-17: ERROR: mousedev_fops: .read() can deadlock .write(); change nonseekable_open -> stream_open to fix.

2019-07-13Input: gtco - bounds check collection indent levelGrant Hernandez
The GTCO tablet input driver configures itself from an HID report sent via USB during the initial enumeration process. Some debugging messages are generated during the parsing. A debugging message indentation counter is not bounds checked, leading to the ability for a specially crafted HID report to cause '-' and null bytes be written past the end of the indentation array. As long as the kernel has CONFIG_DYNAMIC_DEBUG enabled, this code will not be optimized out. This was discovered during code review after a previous syzkaller bug was found in this driver.

2019-07-06Input: gpio_keys_polled - allow specifying name of input deviceEnrico Weigelt, metux IT consult
Instead of hardcoding the input name to the driver name ('gpio-keys-polled'), allow specifying the name of the device via "label" property. If the property is not present (nor name is set in board-supplied platform data), we'll default to the old name.

2019-07-01Input: synaptics - enable SMBUS on T480 thinkpad trackpadCole Rogers
Thinkpad t480 laptops had some touchpad features disabled, resulting in the loss of pinch to activities in GNOME, on wayland, and other touch gestures being slower. This patch adds the touchpad of the t480 to the smbus_pnp_ids whitelist to enable the extra features. In my testing this does not break suspend (on fedora, with wayland, and GNOME, using the rc-6 kernel), while also fixing the feature on a T480.

2019-06-30Input: elan_i2c - export the device id whitelistJeffrey Hugo
Elan_i2c and hid-quirks work in conjunction to decide which devices each driver will handle. Elan_i2c has a whitelist of devices that should be consumed by hid-quirks so that there is one master list of devices to handoff between the drivers. Put the ids in a header file so that hid-quirks can consume it instead of duplicating the list.
