2021-01-23Input: uinput - avoid FF flush when destroying deviceDmitry Torokhov
commit e8b95728f724797f958912fd9b765a695595d3a6 upstream. Normally, when input device supporting force feedback effects is being destroyed, we try to "flush" currently playing effects, so that the physical device does not continue vibrating (or executing other effects). Unfortunately this does not work well for uinput as flushing of the effects deadlocks with the destroy action: - if device is being destroyed because the file descriptor is being closed, then there is noone to even service FF requests; - if device is being destroyed because userspace sent UI_DEV_DESTROY, while theoretically it could be possible to service FF requests, userspace is unlikely to do so (they'd need to make sure FF handling happens on a separate thread) even if kernel solves the issue with FF ioctls deadlocking with UI_DEV_DESTROY ioctl on udev->mutex. To avoid lockups like the one below, let's install a custom input device flush handler, and avoid trying to flush force feedback effects when we destroying the device, and instead rely on uinput to shut off the device properly.

commit ba9a103f40fc4a3ec7558ec9b0b97d4f92034249 upstream. The driver was issuing synchronous uninterruptible control requests without using a timeout. This could lead to the driver hanging on probe due to a malfunctioning (or malicious) device until the device is physically disconnected. While sleeping in probe the driver prevents other devices connected to the same hub from being added to (or removed from) the bus. The USB upper limit of five seconds per request should be more than enough.

commit 7c7da40da1640ce6814dab1e8031b44e19e5a3f6 upstream. In the case of compat syscall ioctl numbers for UI_BEGIN_FF_UPLOAD and UI_END_FF_UPLOAD need to be adjusted before being passed on uinput_ioctl_handler() since code built with -m32 will be passing slightly different values.

keychord driver causes a kernel warning when writing more than (1 << (MAX_ORDER - 1)) * PAGE_SIZE bytes to /dev/keychord. In reality writes to this file should be much smaller, so limiting data size to PAGE_SIZE seems to be appropriate. This change checks write data size and if it's more than PAGE_SIZE causes write to fail.

commit dcaf12a8b0bbdbfcfa2be8dff2c4948d9844b4ad upstream. Fix child-node lookup during probe, which ended up searching the whole device tree depth-first starting at parent rather than just matching on its children. Later sanity checks on node properties (which would likely be missing) should prevent this from causing much trouble however, especially as the original premature free of the parent node has already been fixed separately (but that "fix" was apparently never backported to stable).

2017-04-27input: qpnp-power-on: Add debounce for KPDPWR_N rising edgeAnirudh Ghayal
On certain PMICs, an unexpected assertion on KPDPWR_DBC may be seen during falling edge of KPDPWR_N when it is closer to the rising edge of SLEEP_CLK. This triggers spurious KPDPWR interrupts. Handle this by adding a debounce in SW when the first KPDPWR_N falling edge is seen. The debounce logic is enabled by the DT property 'qcom,kpdpwr-sw-debounce'.

2017-01-09Input: drv260x - fix input device's parent assignmentJingkui Wang
commit 5a8a6b89c15766446d845671d574a9243b6d8786 upstream. We were assigning I2C bus controller instead of client as parent device. Besides being logically wrong, it messed up with devm handling of input device. As a result we were leaving input device and event node behind after rmmod-ing the driver, which lead to a kernel oops if one were to access the event node later. Let's remove the assignment and rely on devm_input_allocate_device() to set it up properly for us.
