* Fix buffer overrun when populating axis label property arrayChase Douglas2012-06-07
| | | | | | | | | | The axis label property array currently only has enough elements for the non-multitouch axes. This change allocates enough space for all axes, which prevents an array overrun write. This may manifest as stack corruption on some platforms.

* Report the correct number of touches for MT protocol B devicesChase Douglas2012-05-25
| | | | | | | | | Protocol B devices report the number of touches by giving a maximum and minimum slot value. The current code ignores the minimum value, which is usually 0, and underreports the number of touches by 1.

* Devices configured as mice need REL_X/YPeter Hutterer2012-05-01
| | | | | | | | | | | | Some keyboards export scroll axes and any absolute axis possible in 11 dimensions. All these axes are mute, except possibly for the scroll wheels. So if a device has a scroll axis, and we're configuring it as mouse, force the x/y axes into existence. This stops the logspam complaining about not enough axes on pointer movement after a xrandr change.

* Copy last valuator values into new touch valuator masksChase Douglas2012-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Evdev is a 100% stateful protocol. The following represents three touches. Two touches begin and end at the same time at (500, 500) and (1000, 1000). The third touch begins after the first two end, and is at (500, 500). ABS_MT_SLOT 0 /* Set touch slot */ ABS_MT_TRACKING_ID 0 /* New touch with ID 0 in slot 0 */ ABS_MT_POSITION_X 500 /* Initial X position */ ABS_MT_POSITION_Y 500 /* Initial Y position */ ABS_MT_SLOT 1 /* Set touch slot */ ABS_MT_TRACKING_ID 1 /* New touch with ID 1 in slot 1 */ ABS_MT_POSITION_X 1000 /* Initial X position */ ABS_MT_POSITION_Y 1000 /* Initial Y position */ SYNC /* End of frame */ ABS_MT_SLOT 0 /* Go back to slot 0 */ ABS_MT_TRACKING_ID -1 /* Touch in slot 0 ended */ ABS_MT_SLOT 1 /* Go to slot 1 */ ABS_MT_TRACKING_ID -1 /* Touch in slot 1 ended */ SYNC /* End of frame */ ABS_MT_SLOT 0 /* Go back to slot 0 */ ABS_MT_TRACKING_ID 2 /* New touch in slot 0 with ID 2 */ SYNC /* End of frame */ ABS_MT_TRACKING_ID -1 /* Touch in last slot (0) ended */ SYNC /* End of frame */ Note that touch 2 has the same X and Y position as touch 0. This is implied because no new value was emitted for slot 0. In fact, Linux will not emit an event in the same slot with the same event type and code unless the value has changed. Thus, we can only assume that all the MT valuators have the same values as they were when they were last sent for the given slot. This change adds an array of valuator mask to hold all the last valuator values that came from evdev for each slot. When a new touch begins, all the last values are copied into it. This patch assumes initial axis values of 0 in each slot. Linux and mtdev do not provide a facility to query the current values of axes in each slot yet. This may cause spurious incorrect touch valuator values at the beginning of an X session, but there's nothing we can do about it right now.

* Prefere relative axis labelling over absolute axis labellingPeter Hutterer2012-01-18
| | | | | | | | | | | | | If a device has both relative and absolute axes, we'd initialise the relative axes but label them with the absolute labels. The current code is broken for mixed mode devices. Most of these devices operate primarily in relative mode, but have some absolute axes available for secondary functionality. For now, label the relative axes properly. We can fix the absolute axes later. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Reviewed-by: Chase Douglas <chase.douglas@canonical.com>
* Force x/y axes to exist on devices with any other axes (#44655)Peter Hutterer2012-01-17
| | | | | | | | | | | | | | | | | Too much in the server relies on x/y to exist and to be axes 0 and 1. So if any relative axes exist, initialize REL_X/Y or ABS_X/Y as well. For servers up to 1.11: a scrollwheel-only device now has relative axes where it only had buttons before. For servers 1.12 or later: the device now has x/y in addition to the scroll axes.
