2019-08-06Input: applespi - use struct_size() helperGustavo A. R. Silva1-2/+1
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.

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.

2019-07-19Input: add Apple SPI keyboard and trackpad driverRonald Tschalär5-0/+2117
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 Wang1-0/+32
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.

2019-07-13Input: gtco - bounds check collection indent levelGrant Hernandez1-3/+17
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.

2019-07-05dmaengine: imx-sdma: remove BD_INTR for channel0Robin Gong1-2/+2
It is possible for an irq triggered by channel0 to be received later after clks are disabled once firmware loaded during sdma probe. If that happens then clearing them by writing to SDMA_H_INTR won't work and the kernel will hang processing infinite interrupts. Actually, don't need interrupt triggered on channel0 since it's pollling SDMA_H_STATSTOP to know channel0 done rather than interrupt in current code, just clear BD_INTR to disable channel0 interrupt to avoid the above case. This issue was brought by commit 1d069bfa3c78 ("dmaengine: imx-sdma: ack channel 0 IRQ in the interrupt handler") which didn't take care the above case.

2019-07-05dmaengine: imx-sdma: fix use-after-free on probe error pathSven Van Asbroeck1-21/+27
If probe() fails anywhere beyond the point where sdma_get_firmware() is called, then a kernel oops may occur. Problematic sequence of events: 1. probe() calls sdma_get_firmware(), which schedules the firmware callback to run when firmware becomes available, using the sdma instance structure as the context 2. probe() encounters an error, which deallocates the sdma instance structure 3. firmware becomes available, firmware callback is called with deallocated sdma instance structure 4. use after free - kernel oops ! Solution: only attempt to load firmware when we're certain that probe() will succeed. This guarantees that the firmware callback's context will remain valid. Note that the remove() path is unaffected by this issue: the firmware loader will increment the driver module's use count, ensuring that the module cannot be unloaded while the firmware callback is pending or running.

2019-07-04drm/imx: notify drm core before sending event during crtc disableRobert Beckett1-2/+2
Notify drm core before sending pending events during crtc disable. This fixes the first event after disable having an old stale timestamp by having drm_crtc_vblank_off update the timestamp to now. This was seen while debugging weston log message: Warning: computed repaint delay is insane: -8212 msec This occurred due to: 1. driver starts up 2. fbcon comes along and restores fbdev, enabling vblank 3. vblank_disable_fn fires via timer disabling vblank, keeping vblank seq number and time set at current value (some time later) 4. weston starts and does a modeset 5. atomic commit disables crtc while it does the modeset 6. ipu_crtc_atomic_disable sends vblank with old seq number and time Fixes: a474478642d5 ("drm/imx: fix crtc vblank state regression") Signed-off-by: Robert Beckett <bob.beckett@collabora.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
