Input: uinput - handle compat ioctl for UI_SET_PHYS

2016-06-08T01:14:32Z

commit affa80bd97f7ca282d1faa91667b3ee9e4c590e6 upstream. When running a 32-bit userspace on a 64-bit kernel, the UI_SET_PHYS ioctl needs to be treated with special care, as it has the pointer size encoded in the command.

Input: uinput - fix crash when using ABS events

2015-09-21T16:32:41Z

Commit b6d30968d86c45a7bb599eaca13ff048d3fa576c (Input: uinput - switch to using for_each_set_bit()) switched driver to use for_each_set_bit(). However during initial write of the uinput structure that contains min/max data for all possible axes none of them are reflected in dev->absbit yet and so we were skipping over all of them and were not allocating absinfo memory which caused crash later when driver tried to sens EV_ABS events: <1>[ 15.064330] BUG: unable to handle kernel NULL pointer dereference at 0000000000000024 <1>[ 15.064336] IP: [] input_handle_event+0x232/0x4e0 <4>[ 15.064343] PGD 0 <4>[ 15.064345] Oops: 0000 [#1] SMP Fixes: b6d30968d86c45a7bb599eaca13ff048d3fa576c Cc: stable@vger.kernel.org Reported-by: Stephen Chandler Paul Tested-by: Stephen Chandler Paul Signed-off-by: Dmitry Torokhov

Input: uinput - switch to using for_each_set_bit()

Use for_each_set_bit to check for set bits in bitmap as it is more efficient and compact. Signed-off-by: Anshul Garg Signed-off-by: Dmitry Torokhov

Input: uinput - add UI_GET_VERSION ioctl

2014-07-21T21:30:42Z

This ioctl is the counterpart to EVIOCGVERSION and returns the uinput-version the kernel was compiled with. Reviewed-by: Peter Hutterer Signed-off-by: David Herrmann Signed-off-by: Dmitry Torokhov

Input: uinput - uinput_validate_absbits() cleanup

2014-07-21T21:28:21Z

This moves basic checks and setup from uinput_setup_device() into uinput_validate_absbits() to make it easier to use. This way, we can call it from other places without copying the boilerplate code. Reviewed-by: Peter Hutterer Signed-off-by: David Herrmann Signed-off-by: Dmitry Torokhov

Input: uinput - add UI_GET_SYSNAME ioctl to retrieve the sysfs path

2014-02-12T23:00:34Z

uinput is used in the xorg-integration-tests suite and in the wayland test suite. These automated tests suites create many virtual input devices and then hook something to read these newly created devices. Currently, uinput does not provide the created input device, which means that we rely on an heuristic to guess which input node was created. The problem is that is heuristic is subjected to races between different uinput devices or even with physical devices. Having a way to retrieve the sysfs path allows us to find without any doubts the event node. Signed-off-by: Benjamin Tissoires Reviewed-by: David Herrmann Signed-off-by: Dmitry Torokhov

Input: uinput - breaks by goto out in uinput_ioctl_handler

2014-01-31T01:30:57Z

The current implementation prevents us to add variable-length ioctl. Use a bunch of gotos instead of break to allow us to do so. No functional changes. Signed-off-by: Benjamin Tisssoires Reviewed-by: David Herrmann Signed-off-by: Dmitry Torokhov

Input: uinput - support injecting multiple events in one write() call

Rework the code in uinput_inject_event so that it matches the code in evdev_write and allows injecting more than one event, or zero events. Signed-off-by: Ryan Mallon Signed-off-by: Dmitry Torokhov

Merge branch 'for-next' of git://github.com/rydberg/linux into next

2012-10-01T21:40:51Z

Merge Henrik's updates to multitouch code. Even though Jiri already pulled them in I need to do it too since my changes to evdev using dynamic major would clash with them.

Input: MT - Add flags to input_mt_init_slots()

2012-09-19T17:50:18Z

Preparing to move more repeated code into the mt core, add a flags argument to the input_mt_slots_init() function. Reviewed-and-tested-by: Benjamin Tissoires Tested-by: Ping Cheng Acked-by: Dmitry Torokhov Signed-off-by: Henrik Rydberg
