* 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.

* 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.

* Add use_proximity bit for BTN_TOOL handling.Peter Hutterer2010-12-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Touchpads send garbage data between BTN_TOOL_FINGER and BTN_TOUCH. This leads to cursor movement towards invalid positions (bottom left corner, usually). Add a new flag "use_proximity" as a delimiter for BTN_TOUCH handling. If unset, the actual proximity bits are ignored, no proximity events are sent and BTN_TOUCH is used for the tool handling.

| | | | | | | | | | | | | | | | | | | | | | | The AUTO feature was the default, MB emulation was on until a middle mouse button was pressed. MB emulation however results in a delay of the first press, causing minor annoyances to the users and being generally confusing when the behaviour before a button press is different to after a button pres. Disable the feature by default instead. There's not a lot of two-button mice around anymore though and the inability to detect two-button mice makes for non-deterministic detection of when the emulation should be on.

* Add EvdevPostButtonEvent API to immediately post a button event (#23269)Peter Hutterer2009-08-14
| | | | | | | | | | | | | | | | The wheel emulation code needs this API. When the timer expires, the event must be posted immediately, not enqueued onto the internal event queue. Otherwise, the emulated middle button press is enqueued only and no event is sent until the next physical event (and its EV_SYN) arrives. Since the timer is triggered outside of the SIGIO and SIGIO is blocked during this period anyway, we could also just enqueue the event and flush by simulating an EV_SYN. It's easier this way though.

* evdev: Use the EvdevPost...Event() functions in the emulation code.Oliver McFadden2009-08-04
| | | | | | | | | | | | | | | | | | This is similar to commit 1f641d75edba7394201c1c53938215bae696791b. It provides the same functionality of queuing the (in this case emulated) events and waiting until an EV_SYN synchronization event is received before posting them to the server. This preserves the order of events (both real and emulated) and ensures that MotionNotify events will always be posted first. It also unifies the event posting into a few small functions which improves maintainability. From this point on, you should never use the xf86Post...Event() functions in new code, but rather the EvdevPost...Event() versions. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
* evdev: Only send the events at synchronization time.Oliver McFadden2009-07-29
| | | | | | | | | | | | | | | | | | | Instead of just posting the button/key press/release events to the server as soon as they arrive, add them to an internal queue and post them once we receive an EV_SYN synchronization event. The motion events are always sent first, followed by the queued events. There will be one motion event and possibly many queued button/key events posted every EV_SYN event. Note that the size of the event queue (EVDEV_MAXQUEUE) is arbitrary and you may change it. If we receive more events than the queue can handle, those events are dropped and a warning message printed.

Hence using FOO_MAX to size the bit vectors representing the capabilities of an evdev device is off by one. Define FOO_CNT values for use with Linux kernels which lack them. Use FOO_CNT whenever we need to know the number of bits needed -- usually to calculate the number of longs needed.
