2024-11-08Input: fix regression when re-registering input handlersDmitry Torokhov1-61/+73
[ Upstream commit 071b24b54d2d05fbf39ddbb27dee08abd1d713f3 ] Commit d469647bafd9 ("Input: simplify event handling logic") introduced code that would set handler->events() method to either input_handler_events_filter() or input_handler_events_default() or input_handler_events_null(), depending on the kind of input handler (a filter or a regular one) we are dealing with. Unfortunately this breaks cases when we try to re-register the same filter (as is the case with sysrq handler): after initial registration the handler will have 2 event handling methods defined, and will run afoul of the check in input_handler_check_methods(): input: input_handler_check_methods: only one event processing method can be defined (sysrq) sysrq: Failed to register input handler, error -22 Fix this by adding handle_events() method to input_handle structure and setting it up when registering a new input handle according to event handling methods defined in associated input_handler structure, thus avoiding modifying the input_handler structure.

2024-11-08Input: edt-ft5x06 - fix regmap leak when probe failsDmitry Torokhov1-1/+18
[ Upstream commit bffdf9d7e51a7be8eeaac2ccf9e54a5fde01ff65 ] The driver neglects to free the instance of I2C regmap constructed at the beginning of the edt_ft5x06_ts_probe() method when probe fails. Additionally edt_ft5x06_ts_remove() is freeing the regmap too early, before the rest of the device resources that are managed by devm are released. Fix this by installing a custom devm action that will ensure that the regmap is released at the right time during normal teardown as well as in case of probe failure. Note that devm_regmap_init_i2c() could not be used because the driver may replace the original regmap with a regmap specific for M06 devices in the middle of the probe, and using devm_regmap_init_i2c() would result in releasing the M06 regmap too early.

Commit 8bccf667f62a ("Input: cypress_ps2 - report timeouts when reading command status") uncovered an existing problem with cypress_ps2 driver: it tries waiting on a PS/2 device waitqueue without using the rest of libps2. Unfortunately without it nobody signals wakeup for the waiting process, and each "extended" command was timing out. But the rest of the code simply did not notice it. Fix this by switching from homegrown way of sending request to get command response and reading it to standard ps2_command() which does the right thing.

2024-08-18Input: i8042 - add forcenorestore quirk to leave controller untouched even on s3Werner Sembach2-6/+14
On s3 resume the i8042 driver tries to restore the controller to a known state by reinitializing things, however this can confuse the controller with different effects. Mostly occasionally unresponsive keyboards after resume. These issues do not rise on s0ix resume as here the controller is assumed to preserved its state from before suspend. This patch adds a quirk for devices where the reinitialization on s3 resume is not needed and might be harmful as described above. It does this by using the s0ix resume code path at selected locations. This new quirk goes beyond what the preexisting reset=never quirk does, which only skips some reinitialization steps.

From: Dmitry Torokhov <dmitry.torokhov@gmail.com> When exercising uinput interface syzkaller may try setting up device with a really large number of slots, which causes memory allocation failure in input_mt_init_slots(). While this allocation failure is handled properly and request is rejected, it results in syzkaller reports. Additionally, such request may put undue burden on the system which will try to free a lot of memory for a bogus request. Fix it by limiting allowed number of slots to 100. This can easily be extended if we see devices that can track more than 100 contacts.

It's not all that useful for a "write a whole driver in rust" type of thing, but the firmware bindings do help out the phy rust drivers, and the driver core bindings give a solid base on which others can start their work. There is still a long way to go here before we have a multitude of rust drivers being added, but it's a great first step. - driver core const api changes. This reached across all bus types, and there are some fix-ups for some not-common bus types that linux-next and 0-day testing shook out. This work is being done to help make the rust bindings more safe, as well as the C code, moving toward the end-goal of allowing us to put driver structures into read-only memory.

2024-07-12Input: yealink - simplify locking in sysfs attribute handlingDmitry Torokhov1-52/+20
The locking rules in the driver came from era when sysfs attributes could live past the point of time when device would be unbound from the driver, and so used module-global semaphore (potentially shared between multiple yealink devices). Thankfully these times are long gone and attributes will not be accessible once they are removed. Simplify the logic by moving to per-device mutex, stop checking if there is driver data instance attached to the interface, and use guard notation to acquire the mutex.

Both KUNIT_FAIL and KUNIT_ASSERT_FAILURE defined to KUNIT_FAIL_ASSERTION with different tpye of kunit_assert_type. The current naming of KUNIT_ASSERT_FAILURE and KUNIT_FAIL_ASSERTION is confusing due to their similarities. To improve readability and symmetry, renames KUNIT_ASSERT_FAILURE to KUNIT_FAIL_AND_ABORT. Makes the naming consistent, with KUNIT_FAIL and KUNIT_FAIL_AND_ABORT being symmetrical. Additionally, an explanation for KUNIT_FAIL_AND_ABORT has been added to clarify its usage.

2024-07-08Input: himax_hx83112b - add support for HX83100AFelix Kaechele1-0/+17
The HX83100A is a bit of an outlier in the Himax HX831xxx series of touch controllers as it requires reading touch events through the AHB interface of the MCU rather than providing a dedicated FIFO address like the other chips do. This patch implements the specific read function and introduces the HX83100A chip with an appropriate i2c ID and DT compatible string. The HX83100A doesn't have a straightforward way to do chip identification, which is why it is not implemented in this patch.
