Alan Coopersmith 789d64e19a Remove unneccesary casts from WriteToClient calls
Casting return to (void) was used to tell lint that you intended
to ignore the return value, so it didn't warn you about it.

Casting the third argument to (char *) was used as the most generic
pointer type in the days before compilers supported C89 (void *)
(except for a couple places it's used for byte-sized pointer math).

When allocating new global privates, make sure the gpu
screens get their private offsets updated.

This only affects GPU screens that enumerate before the non-GPU

Dave Airlie f2da2c1204 randr: add initial scanout pixmap support (v3)
When randr notices a crtc configuration request for a slave device,
it checks if the slave allocated pixmap exists and is suitable,
if not it allocates a new shared pixmap from the master, shares
it to the slave, and starts the master tracking damage to it,
to keep it updated from the current front pixmap.

If the resize means the crtc is no longer used it will destroy
the slave pixmap.

This adds the concept of a scanout_pixmap to the randr_crtc object,
and also adds a master pixmap pointer to the pixmap object, along
with defining some pixmap helper functions for getting pixmap box/regions.

v2: split out pixmap sharing to a separate function.

v3: update for void *

Keith Packard 9d457f9c55 Add screen-specific privates.
Screen-specific privates areas are only allocated for objects related
to the target screen; objects allocated for other screens will not
have the private space reserved. This saves memory in these objects
while also allowing hot-plug screens to have additional private
allocation space beyond what the core screens are using.

Drivers are encouraged to switch to this mechanism as it will reduce
memory usage in multi-GPU environments, but it is only required for
drivers which will be loaded after the server starts, like
modesetting.

Objects providing screen-specific privates *must* be managed by the
screen-specific private API when allocating or initializing privates
so that the per-screen area can be initialized properly.

The objects which support screen-specific privates are:

	Windows
	Pixmaps
	GCs
	Pictures

Extending this list to include Colormaps would be possible, but
require slightly more work as the default colormap is created before
all colormap privates are allocated during server startup, and hence
gets a bunch of special treatment.

Of particular note, glyphs are *not* capable of supporting
screen-specific privates as they are global objects, not allocated on
a screen-specific basis, and so each driver must be able to see their
privates within the glyph.

Peter Hutterer 4c68f5d395 dix: disable all devices before shutdown
f3410b97cf introduced a regression on server
shutdown. If any button or key was held on shutdown (ctrl, alt, backspace
are usually still down) sending a raw event will segfault the server. The
the root windows are set to NULL before calling CloseDownDevices().

Avoid this by disabling all devices first when shutting down. Disabled
devices won't send events anymore.

Master keyboards must be disabled first, otherwise disabling the pointer
will trigger DisableDevice(keyboard) and the keyboard is removed from the
inputInfo.devices list and moved to inputInfo.off_devices. A regular loop
through inputInfo.devices would thus jump to off_devices and not recover.

    Removing the scrnIndex is a bit more involved and I'm not sure its worth

Peter Hutterer af88b43f9e dix: don't emulate scroll events for non-existing axes (#47281)
Test case:
- create a device with REL_HWHEEL and ABS_X and ABS_Y. evdev 2.7.0 will set
  that up as device with 1 relative axis
- move pointer to VGA1
- xrandr --output VGA1 --off

Warps the pointer to the new spot and calls GPE with the x/y mask bits set.
When running through the loop to check for scroll event, this overruns the
axes and may try to emulate scroll events based on random garbage in the
memory. If that memory contained non-zero for the scroll type but near-zero
for the increment field, the server would hang in an infinite loop.

Chase Douglas d0449851d1 Create a new dix touch record for an emulated touch with no listeners
As a special case, if a still physically active pointer emulated touch
has no listeners and the device is explicitly grabbed for pointer
events, create a new dix touch record for the grab only.

This allows for clients to "hand off" grabs. For example, when dragging
a window under compiz the window decorator sees the button press and
then ungrabs the implicit grab. It then tells compiz to grab the device,
and compiz then moves the window with the pointer motion. This is racy,
but is allowed by the input protocol for pointer events when there are
no other clients with a grab on the device.

Chase Douglas 12188c8a8a Use touch state when querying pointer through core protocol
QueryPointer is part of the core protocol. As such, it knows nothing
about touch devices. Touches are converted to button 1 press, pointer
motion, and button 1 release for core clients, so we should ensure the
pointer state mask has button 1 set when XQueryPointer is used.

Daniel Kurtz c5a45b0f76 dix: don't BUG_WARN for button events from button-only device
Events from button-only devices still need coordinates, and they get them
from scale_to_desktop().  Therefore, a dev without valuators is not a bug.
However, a dev with valuators, but less than two of them still is a bug.

This was noticed when unplugging a "Creative Technology SB Arena Headset",
which has some BTNs and some KEYs, but no REL or ABS valuators.
It emits [BTN_3] = 0 on unplug, which would trigger the BUG_WARN.

Previously, we only had one idle alarm that was triggered for all devices,

Add system SyncCounters for each device (named "DEVICEIDLETIME x", with x
being the device id) that trigger on that device only. This allows for
enabling/disabling devices based on interaction with other devices.

Popular use-case: disable the touchpad when the keyboard just above the
touchpad stops being idle.

Peter Hutterer c0b0a9bce9 dix: add dtrace probes to input API
For driver debugging, it is helpful to know whether the driver has actually
submitted an event to the server. dtrace hooks can help here.

Note that GetPointerEvents and friends may also be triggered by the server
for other emulated devices, some care must be taken when analysing the
results.

Additional difficulty: proximity events have a run-time assigned type, so
this may make automatic detection a tad harder. If in doubt, go for any
event > 64 since the only two that can have that value are ProximityIn and
ProximityOut.

An example systemtap script is below:

  # Compile+run with
  #       stap -g xorg.stp /usr/bin/Xorg
  #

  function print_valuators:string(nvaluators:long, mask_in:long, valuators_in:long) %{

          double *valuators = (double*)THIS->valuators_in;
          char str[128] = {0};
          char *s = str;

  #define BitIsSet(ptr, bit) (((unsigned char*)(ptr))[(bit)>>3] & (1 << ((bit) & 7)))

          s += sprintf(s, "nval: %d ::", (int)THIS->nvaluators);
          for (i = 0; i < THIS->nvaluators; i++)
          {

                      s += sprintf(s, "%d", (int)valuators[i]);
          }

          sprintf(THIS->__retvalue, "%s", str);

Chase Douglas 31df08a449 Use a new sprite trace for indirect touches when all touches have physically ended
All touches of an indirect device, such as a trackpad, are sent to the
same window set. When there are no active touches, a new window set is
created; otherwise, the window set of an existing touch is copied.

The current code checks for any logically active touches. This includes
touches that have physically ended but are still logically active due to
unhandled touch grabs. Instead, we want a new window set whenever there
are no physically active touches.

This change skips over logically active but pending end touches, which
are touches that have physically ended.

		dir=`dirname $file`
		base=`basename $file .o`

does not depend on the touch's X and Y values. Thus, we don't need to
set the values for every indirect touch event.

On top of this, the previous X and Y values aren't stored for indirect
touches, so without this change the axes get erroneously set to 0.

grab time to ensure that the request pertains to the current grab in the

This change ensures that the server's notion of the grab time is the
time of the event that activated the grab rather than the time that the
grab is actually activated.

Adam Jackson 78fa121f40 dix: Extend initial connection handshake for forwarding proxies
Forwarding proxies like sshd will appear to be local, even though they
aren't really.  This leads to weird behaviour for extensions that truly
require running under the same OS services as the client, like MIT-SHM
and DRI2.

Add two new legal values for the initial connection's byteOrder field,
'r' and 'R'.  These act like 'l' and 'B' respectively, but have the side
effect of forcing the client to be treated as non-local.  Forwarding
proxies should attempt to munge the first packet of the connection
accordingly; older servers will reject connections thusly munged, so the
proxy should fall back to passthrough if the munged connection attempt
fails.

Note: this commit is a retroactive commit extracted from a series of ~50

from scratch.

Pointer processing tree is roughly:
- ProcessOtherEvents
  - ProcessTouchEvents
    - DeliverTouchEvents
      - DeliverTouchBeginEvent|DeliverTouchEndEvent|...
        - DeliverOneTouchEvent

Peter Hutterer 40475261ea dix: add touch event history helper functions
If touch client has not registered for ownership events and a grab above
that client is rejected, the client needs to receive the complete event
history.

The history currently doesn't really do fancy overflow handling. We assume
that the first TOUCH_HISTORY_SIZE events are the important ones and anything
after that is dropped. If that is a problem, fix the client that takes > 100
event to decide whether to accept or reject.

Events marked with TOUCH_CLIENT_ID or TOUCH_REPLAYING must not be stored in
the history, they are events created by the DIX to comply with the protocol.
Any such event should already be in the history anyway.

A fixme in this patch: we don't have a function to actually deliver the
event yet.

Daniel Stone 3fb258ca28 input: add a TouchClassRec to the devices
These structs will be used to store touch-related data, events and
information.

Drivers must call InitTouchClassDeviceStruct to set up a multi-touch capable
device.

Touchpoints for the DDX and the DIX are handled separately - touchpoints
submitted by the driver/DDX will be stored in the DDXTouchPointInfoRec. Once
the touchpoints are processed by the DIX, new TouchPointInfoRecs are created
and stored. This process is already used for pointer events with the
last.valuators field.

Note that this patch does not actually add the generation of touch events,
only the required structs.

TouchListeners are (future) recipients of touch or emulated pointer events.
Each listener is in a state, depending which event they have already
received. The type of listener defines how the listener got to be one.

Alan Coopersmith 50b1097643 Constify the reason string throughout the authorization check framework
Almost all of the places the string is assigned point to a literal
string constant, so use const char * for those, and const char **
for function calls that return it via an argument.   Fortunately
the top level function, ClientAuthorized, which returns the string
as its return value is called from only one place, ProcEstablishConnection.

ProcEstablishConnection stores either that return value or a string literal
in char *reason.  It only uses reason as an argument to SendConnSetup.
SendConnSetup passes the reason argument to strlen & WriteToClient,
both of which already have const qualifiers on their args.
Thus added const to the reason variable in ProcEstablishConnection
and the reason argument to SendConnSetup.

Aaron Plattner 8329afa59d dix: Reinstate GetImage window size check
Commit 587c3a2d19 fixed DoGetImage to
check windows against their backing drawables, rather than against the
screen dimensions, to prevent reading outside the bounds of redirected
windows' backing pixmaps (see bug #22804).  Unfortunately, while
making that change I also removed the check that the rectangle is
contained within the bounds of the source window, which is a violation
of the specification:

    If the drawable is a window, the window must be viewable, and it
    must be the case that, if there were no inferiors or overlapping
    windows, the specified rectangle of the window would be fully
    visible on the screen *and wholly contained within the outside
    edges of the window* (or a Match error results). Note that the
    borders of the window can be included and read with this request.

    (emphasis mine)

Reinstate the window dimension check, to return BadMatch if the
GetImage request falls outside the bounds of the window.

Peter Hutterer d7c44a7c97 dix: block signals when closing all devices
When closing down all devices, we manually unset master for all attached
devices, but the device's sprite info still points to the master's sprite
info. This leaves us a window where the master is freed already but the
device isn't yet. A signal during that window causes dereference of the
already freed spriteInfo in mieqEnqueue's EnqueueScreen macro.

Simply block signals when removing all devices. It's not like we're really
worrying about high-responsive input at this stage.

occured, respectively. (This fixes a bug where we'd get two release events
for each legacy button event)

Peter Hutterer 401150d7dc input: change pointer screen crossing behaviour for multiple ScreenRecs
miPointerSetPosition traditionally took coordinates on a per-screen basis,
triggering a screen switch when these went out-of-bounds. For absolute
devices, this prevented screen crossing in the negative x/y direction.

This patch changes the event generation patch to handle screen coordinates
in a desktop range (i.e. all screens together). Screen switches are
triggered when these coordinates are not on the current screen.

This unifies the pointer behaviour of single ScreenRec multihead and
multiple ScreenRecs multihead in that the cursor by default moves about the
whole screen rather than be confined to one single screen. The
transformation matrix may then be used to actually confine the cursor to the
screen again.

Note: fill_pointer_events has to deal with several different coordinate
systems. Make sure you read the comment before trying to understand the code.

Peter Hutterer 3b36fd1b49 mi: switch miPointerSetPosition to take doubles
Don't switch between doubles and ints in the caller, instead take doubles in
miPointerSetPosition and do the conversion there. For full feature we should
change everything down from here for doubles too.

Functional change: previously we'd restore the remainder regardless of
screen switching/confinement (despite what the comment said). Now,
screen changing or cursor constraints will cause the remainder be clipped
off. This should happen for cursor constraints but arguably not for screen
crossing.

This also corrects a currently wrong comment about miPointerSetPosition's
input coordinates.

Peter Hutterer 3304bbff9b Input: Add smooth-scrolling support to GetPointerEvents
For scroll wheel support, we used to send buttons 4/5 and 6/7 for
horizontal/vertical positive/negative scroll events.  For touchpads, we
really want more fine-grained scroll values.  GetPointerEvents now
accepts both old-school scroll button presses, and new-style scroll axis
events, while emitting both types of events to support both old and new
clients.

This works with the new XIScrollClass to mark axes as scrolling axes.
Drivers mark any valuators that send scroll events with SetScrollValuator.
(Currently missing: the XIDeviceChangeEvent being sent when a driver changes
a scroll axis at run-time. This can be added later.)

Note: the SCROLL_TYPE enums are intentionally different values to the XI2
proto values to avoid copy/overlapping range bugs.

If AddResource fails, it will automatically free the object that was

FreeResource also calls the deleteFunc. In both cases it's wrong to call
the destroy hook manually.

Peter Hutterer 2bfb802839 dix: don't XWarpPointer through the last slave anymore (#38313)
This line was introduced pre-1.6 to fix Bug 19297. The effect of warping
through the VCP then was that if a device had custom valuator ranges, the
warp position would be wrong. The better device for this effect is the the
XTest device.

This fixes a server crash where the lastSlave is a pointer device without
valuators (Bug 38313#0).

And while we're at it, make sure the Xinerama code-path does the same.

Peter Hutterer 7998797975 dix: abstract XI2 filter mask lookup
Don't access the xi2mask bytes directly or calculate the offsets manually,
use a few helper functions instead. XI2 masks are a bit weird in the event
handling code since they slot onto the legacy code. For core/XI 1.x events,
the event mask is a CARD32. That mask is used together with the event filter
(also 32 bit) to determine if event delivery should be attempted.
XI2 masks are of arbitrary size and their mask is simply the byte of the
mask that contains the event mask. Likewise, the filter is a single byte
matching that mask. Provide helper functions get these bytes and masks in
the right order instead of accessing them manually.

EventIsDeliverable should be part of this cleanup patch but it will be
gutted with the next patch.

Daniel Stone 7d2543a3cb XKB: Add debug key actions for grabs & window tree
Add four new private XKB actions for debugging:
    * PrGrbs: print active grabs to the log file
    * Ungrab: ungrab all currently active grabs
    * ClsGrb: kill clients with active grabs
    * PrWins: dump the current window tree to the log file

To use these, you need to modify your XKB maps, e.g. the following to
have Ctrl+Alt+(F9-F12) mapped to the above:
 - compat/xfree86:
    interpret XF86LogGrabInfo {
        action = Private(type=0x86, data="PrGrbs");
    };
    interpret XF86Ungrab {
        action = Private(type=0x86, data="Ungrab");
    }
    interpret XF86ClearGrab {
        action = Private(type=0x86, data="ClsGrb");
    }
    interpret XF86LogWindowTree {
        action = Private(type=0x86, data="PrWins");
    }

 - symbols/pc:
    key <FK09> {        type="CTRL+ALT", [ Return, XF86LogGrabInfo      ]   };
    key <FK10> {        type="CTRL+ALT", [ Return, XF86Ungrab           ]   };
    key <FK11> {        type="CTRL+ALT", [ Return, XF86ClearGrab        ]   };
    key <FK12> {        type="CTRL+ALT", [ Return, XF86LogWindowTree    ]   };

At the moment, this only works if the grabbing client continues to call
AllowEvents, as the server does no event processing at all when a device
is frozen.

Peter Hutterer b75cdb5bf7 dix: drop x/y back into the right valuators after transformation.
If the matrix is used for rotation, the coordinates affected may change.
e.g. a valuator mask of (x, nil) becomes [x, lasty] and is rotated to
[lasty, x]. Since the second value was unset, we would not drop x back into
the mask, resulting in a loss of movement.

Thus, drop any value that changed after applying the matrix into the
valuators. Thus, the example above becomes
(x, nil) → [x, lasty] → [lasty, x] → (lasty, x)

Peter Hutterer 236ed6f506 dix: split out client delivery from DeliverEventsToWindow
No real functional changes, this is just for improved readability.

DeliverEventsToWindow used to return an int to specify the number of
deliveries (or rejected deliveries if negative). The number wasn't used by
any caller other than for > 0 comparison.

This patch also changes the return value to be -1 or 1 even in case of
multiple deliveries/rejections. The comment was updated accordingly.

A future patch should probably use the enum EventDeliveryState for
DeliverEventsToWindow.

Peter Hutterer 20fb07f436 input: remove DDX event list handling
The current approach to event posting required the DDX to request the event
list (allocated by the DIX) and then pass that list into QueuePointerEvent
and friends.

Remove this step and use the DIX event list directly. This means that
QueuePointerEvent is not reentrant but it wasn't before anyway.

Expand what this does to print the event content and a backtrace, so at
least we know where we're coming from. Only the first 32 bytes are printed
since if something goes wrong, the event we have is almost certainly an
xEvent or xError, both restricted to 32 bytes.

each DDX has its own copy, I've taken the darwin one,
though I'm not sure why it needs the pOldClip piece that nobody
else has and the commit msg is like an "Updates from magic land"
type message.

This removes the main uses of pWin->winSize from the DDXen.

v2: drop old clip like ajax suggests.

The code to set sync.other in DeliverGrabbedEvents is supposed to reset

rather optimistic in resetting sync.other for _all_ devices.

This would fall apart given two sets of MDs (A paired with B, Y paired
with Z), where both MDs were in FREEZE_BOTH_NEXT_EVENT due to being
called with SyncBoth, where no event had yet triggered the grab.  An
event being processed on MD A would result in B, Y and Z all having
sync.other set to A's grab, rather than just B.

Ville Syrjälä f3480286ae composite: Support updating an arbitrary subtree
Rename compUpdateWindow to compPaintWindowToParent and split the child
walk to compPaintChildrenToWindow. Calling compPaintChildrenToWindow
allows an arbitrary subtree to be updated, instead of having to update
all the windows. This will be used to make sure all the descendants are
copied to the parent when the parent window contents need to be accessed
in IncludeInferios sub-window mode.

WindowRec has a new member 'damagedDescendants' that is used to keep
track of which subtrees need updating. When a window is damaged,
'damagedDescendants' will be set for all the ancestors, and when a
subtree is updated, the tree walk can be stopped early if no damaged
descendants are present.

CompScreenRec no longer needs the 'damaged' member since the root
window's 'damagedDescendants' provides the same information.

Tiago Vignatti 8976e9766e dix: adds support for none root window background
It lets the driver notify the server whether it can draw a background when
'-background none' option is used by the system platform. Use cases for that
could be video drivers performing mode-setting in kernel time, before X is up,
so a seamless transition would happen until X clients start to show up.

If the driver can copy the framebuffer cleanly then it can set the flag
(canDoBGNoneRoot), otherwise the server will fallback to the normal behaviour.
The system must explicit indicates willingness of doing so through
'-background none'. We could do this option as default; in such case,
malicious users would be able to steal the framebuffer with a bit of tricks.

For instance, I can see the content of my nVidia Quadro FX 580 framebuffer
old X session modifying a bit nv driver:

     xf86DPMSInit(pScreen, xf86DPMSSet, 0);

-    /* Clear the screen */
-    if(pNv->xaa) {
-        /* Use the acceleration engine */
-        pNv->xaa->SetupForSolidFill(pScrn, 0, GXcopy, ~0);
-        pNv->xaa->SubsequentSolidFillRect(pScrn,
-            0, 0, pScrn->displayWidth, pNv->offscreenHeight);
-        G80DmaKickoff(pNv);
-    } else {
-        /* Use a slow software clear path */
-        memset(pNv->mem, 0, pitch * pNv->offscreenHeight);
-    }
+    pScreen->canDoBGNoneRoot = TRUE;

Chase Douglas 65c0fc81eb Add support for per-axis valuator modes (Relative/Absolute)
The XI2 protocol supports per-axis modes, but the server so far does
not. This change adds support in the server.

A complication is the fact that XI1 does not support per-axis modes.
The solution provided here is to set a per-device mode that defines the
mode of at least the first two valuators (X and Y). Note that initializing
the first two axes to a different mode than the device mode will fail.

For XI1 events, any axes following the first two that have the same mode
will be sent to clients, up to the first axis that has a different mode.
Thus, if a device has relative, then absolute, then relative mode axes,
only the first block of relative axes will be sent over XI1.

Since the XI2 protocol supports per-axis modes, all axes are sent to the
client.

Peter Hutterer 675f4a8525 Abstract valuator masks through a set of APIs.
This commit introduces an abstraction API for handling masked valuators. The
intent is that drivers just allocate a mask, set the data and pass the mask
to the server. The actual storage type of the mask is hidden from the
drivers.

The new calls for drivers are:
    valuator_mask_new()     /* to allocate a valuator mask */
    valuator_mask_zero()    /* to reset a mask to zero */
    valuator_mask_set()     /* to set a valuator value */

The new interface to the server is
    xf86PostMotionEventM()
    xf86PostButtonEventM()
    xf86PostKeyboardEventM()
    xf86PostProximityEventM()

all taking a mask instead of the valuator array.

The ValuatorMask is currently defined for MAX_VALUATORS fixed size due to
memory allocation restrictions in SIGIO handlers.

For easier review, a lot of the code still uses separate valuator arrays.
This will be fixed in a later patch.

This patch was initially written by Chase Douglas.

Joe Shaw e354ccac36 fix a sign problem with valuator data.
Without this patch, any negative valuator value is wrong when returned
from XQueryDeviceState().  This is a regression from at least xserver
1.4.

Valuator data is set in dix/getevents.c:set_valuators() by copying
signed int values into an unsigned int field
DeviceEvent.valuators.data.

That data is converted into a double with an implicit cast by
assignment to axisVal[i] in Xi/exevents.c:UpdateDeviceState().

That double is converted back to a signed int in
queryst.c:ProcXQueryDeviceState().  If the original value in
set_valuators() is negative, the double value will be > 2^31 and the
conversion back to a signed int is undefined.  (Although I
consistently see the value -2^31.)

Fix this by changing the definition of DeviceEvent.valuators.data from
uint32_t to int32_t.

If NB was the last one to send an event through the master when A+B is

Peter Hutterer 651c36e95e xkb: post-fix PointerKeys button events with a DeviceChangedEvent.
commit 1432785839
    xkb: release XTEST pointer buttons on physical releases. (#28808)
revealed a bug with the XTEST/PointerKeys interaction.

Events resulting from PointerKeys are injected into the event processing
stream, not appended to the event queue. The events generated for the fake
button press include a DeviceChangedEvent (DCE), a raw button event and the
button event itself. The DCE causes the master to switch classes to the
attached XTEST pointer device.

Once the fake button is processed, normal event processing continues with
events in the EQ. The master still contains the XTEST classes, causing some
events to be dropped if e.g. the number of valuators of the event in the
queue exceeds the XTEST device's number of valuators.

Example: the EQ contains the following events, processed one-by-one, left to
right.

[DCE (dev)][Btn down][Btn up][Motion][Motion][...]
                  ^ XkbFakeDeviceButton injects [DCE (XTEST)][Btn up]

Thus the event sequence processed looks like this:

[DCE (dev)][Btn down][Btn up][DCE (XTEST)][Btn up][Motion][Motion][...]

The first DCE causes the master to switch to the device. The button up event
injects a DCE to the XTEST device, causing the following Motion events to be
processed with the master still being on XTEST classes.

This patch post-fixes the injected event sequence with a DCE to restore the
classes of the original slave device, resulting in an event sequence like
this:
[DCE (dev)][Btn down][Btn up][DCE (XTEST)][Btn up][DCE (dev)][Motion][Motion]

Note that this is a simplified description. The event sequence injected by
the PointerKeys code is injected for the master device only and the matching
slave device that caused the injection has already finished processing on
the slave. Furthermore, the injection happens as part of the the XKB layer,
before the unwrapping of the processInputProc takes us into the DIX where
the DCE is actually handled.

Bug reproducible with a device that reports more than 2 valuators. Simply
cause button releases on the device and wait for a "too many valuators"
warning message.

Behaviour of earlier X servers was to deliver the ButtonPress event
unconditionally, regardless of the actual event mask being set. Thus, a
GrabButton event will always deliver the button press event, a GrabKey
always the key press event, etc. Same goes for XI and XI2.

Reproducible with a simple client requesting a button grab in the form of:
    XGrabButton(dpy, AnyButton, AnyModifier, win, True, ButtonReleaseMask,
                GrabModeAsync, GrabModeAsync, None, None);

On servers before MPX/XI2, the client will receive a button press and
release event. On current servers, the client receives only the release.
Clients that expect the press event to be delivered unconditionally may
leave the user with a stuck grab.

XTS test results for XGrabButton are identical with and without this patch.

Peter Hutterer 1884db430a Revert "dix: use the event mask of the grab for TryClientEvents."
Behaviour of earlier X servers was to deliver the ButtonPress event
unconditionally, regardless of the actual event mask being set. This is
documented in the protocol:
"This request establishes a passive grab.  In the future, the pointer is
actively grabbed as described in GrabPointer, the last-pointer-grab time is
set to the time at which the button was pressed (as transmitted in the
ButtonPress event), and the ButtonPress event is reported if all of the
following conditions are true:
    <list of conditions, event mask is not one of them>"

Thus, a GrabButton event will always deliver the button press event, a
GrabKey always the key press event, etc. Same goes for XI and XI2.

Reproducible with a simple client requesting a button grab in the form of:
    XGrabButton(dpy, AnyButton, AnyModifier, win, True, ButtonReleaseMask,

XTS Xlib13 XGrabButton 5/39 now passes.

Dave Airlie 959a1eaf1c composite: use config notify hook to do pixmap resize.
Since reallocating the backing pixmap can fail, we need to try and do
it before any other side effects of reconfiguring the window happen.

This changes the ConfigNotify hook to return status, and moves the
composite window reconfiguration wrappers to ConfigNotify. They all
basically did the same thing, so we can drop the MoveWindow,
ResizeWindow, ChangeBorderWidth wrappers, and allow ConfigNotify to do
all the work. If reallocation fails we fail before we send any
confiureNotify events, or enter the area we can't recover from.

The only place we now enforce 32k limits are in EXA/UXA/fb, so drivers
that don't use this should probably deal with it in their pixmap
allocate if they don't already.

This also breaks ABI, so we need an alternate fix for older servers,
working on the X server makes me realise why I'm a kernel hacker.

Peter Korsgaard 6cccf0131c dix: add 3x3 transformation matrix xinput property for multi-head handling
For absolute input devices (E.G. touchscreens) in multi-head setups,
we need a way to bind the device to an randr output. This adds the
infrastructure to the server to allow us to do so.

positionSprite() scales input coordinates to the dimensions of the shared
(total) screen frame buffer, so to restrict motion to an output we need to
scale/rotate/translate device coordinates to a subset of the frame buffer
before passing them on to positionSprite.

This is done here using a 3x3 transformation matrix, which is applied to
the device coordinates using homogeneous coordinates, E.G.:

[ c0 c1 c2 ]   [ x ]
[ c3 c4 c5 ] * [ y ]
[ c6 c7 c8 ]   [ 1 ]

Notice: As input devices have varying input ranges, the coordinates are
first scaled to the [0..1] range for generality, and afterwards scaled
back up.

E.G. for a dual head setup (using same resolution) next to each other, you
would want to scale the X coordinates of the touchscreen connected to the
both heads by 50%, and translate (offset) the coordinates of the rightmost
head by 50%, or in matrix form:

   left:            right:
[ 0.5 0 0 ]     [ 0.5 0 0.5 ]
[ 0   1 0 ]     [ 0   1 0   ]
[ 0   0 1 ]     [ 0   0 0   ]

Which can be done using xinput:

xinput set-prop <left> --type=float "Coordinate Transformation Matrix" \
       0.5 0 0 0 1 0 0 0 1

xinput set-prop <right> --type=float "Coordinate Transformation Matrix" \
       0.5 0 0.5 0 1 0 0 0 1

Likewise more complication setups involving more heads, rotation or
different resolution can be handled.

Peter wants to get a larger patch sequence put together and I didn't
read past the commit message to see the 'don't take this patch
please'.

This reverts commit 531ff40301.
2010-05-26 07:54:35 -07:00
Peter Hutterer 531ff40301 Add a "flags" field to DeleteInputDeviceRequest.
Some input drivers need to implement an internal hotplugging scheme for
dependent devices to provide multiple X devices off one kernel device file.
Such dependent devices can be added with NewInputDeviceRequest() but they are
not removed when the config backend calls DeleteInputDeviceRequest(),
leaving the original device to clean up.

Example of the wacom driver:

config/udev calls NewInputDeviceRequest("stylus")

wacom PreInit calls
        NewInputDeviceRequest("eraser")
        NewInputDeviceRequest("pad")
        NewInputDeviceRequest("cursor")
        PreInit finishes.

When the device is removed, the config backend only calls
DeleteInputDeviceRequest for "stylus". The driver needs to call
DeleteInputDeviceRequest for the dependent devices eraser, pad and cursor to
clean up properly.
However, when the server terminates, DeleteInputDeviceRequest is called for
all devices - the driver must not remove the dependent devices to avoid
double-frees. There is no method for the driver to detect why a device is
being removed, leading to elaborate guesswork and some amount of wishful
thinking.

Though the input driver's UnInit already supports flags, they are unused.
This patch uses the flags to supply information where the
DeleteInputDeviceRequest request originates from, allowing a driver to
selectively call DeleteInputDeviceRequest when necessary.

Also bumps XINPUT ABI.

ActivateDevice was ignoring errors from DeviceCursorInitialize, so
cursor-related calls failed later. Jeremy Huddleston saw that crash in
miPointerConstrainCursor, while with Xvfb I saw it in
miSpriteRealizeCursor.

miDCDeviceCleanup frees any non-NULL GCs. miDCDeviceInitialize calls
Cleanup on any failure, but if it failed early then some of the pointers
in the miDCBufferPtr were garbage. Switch from malloc to calloc to
ensure everything's initialized safely first.

With these two fixes, if CreateGC fails then the server gracefully fails
in FatalError instead of segfaulting.

Jamey Sharp 2d7eb4a19b Pre-validate ChangeGC XIDs.
In order to execute a wire-level ChangeGC request, we need to look up
the resources named by any XIDs in the value-list. Various places in the
server already have pointers to the resources they want to set into the
GC, though, so over time the interface has evolved to accept either XIDs
or pointers, with several different function call signatures used in
different eras.

This patch makes the existing code require pointers to resources rather
than XIDs, and adds a simple wrapper that looks up any XIDs. The old
dixChangeGC API is preserved by delegating to whichever implementation
is appropriate.

This affects error-handling: If any of the XIDs are invalid, then the GC
is unchanged, and its ChangeGC callback is not invoked. This change is
allowed by the protocol spec, which says, "The order in which components
are verified and altered is server-dependent. If an error is generated,
a subset of the components may have been altered."

Kristian Høgsberg 6d7ba5e0fc dix: Update element count in FreeResource*()
FreeResource() keeps clientTable[cid].elements up to date with the
number of resources allocated to the client.  The other free
resource functions (FreeResourceByType(),
FreeClientNeverRetainResources() and FreeClientResources()) don't
maintain this invariant.

Typically, the only consequence is that the element count is too high
and we end up allocating the hash table bigger than necessary.  However,
FreeResource() also relies on the element count to restart the search if
the list of resources has been changed during a resource destruction
callback.  Since FreeResourceByType() doesn't update the count, if we call
that from a resource destruction callback from FreeResource(), the
loop isn't restarted and we end up following an invalid next pointer.

Furthermore, LookupClientResourceComplex() and
FreeClientNeverRetainResources() don't use the element count to detect
if a callback deleted a resource and may end up following an invalid
next pointer if the resource system is called into recursively.

Peter Hutterer 9ddbb03fa5 dix: Fix crash in DeliverGrabbedEvents.
If both devices are synchronously grabbed, first with a GrabPointer, then
with a GrabKeyboard (GrabModeSync on both), sync.other of each device points
to the grab of the respective other device.

If the keyboard is then thawed through a AllowSome request, the VCK's
sync.other is reset to NULL. Subsequently, an event on the VCP would crash
the server when dereferencing sync.other on the VCP.

The check's purpose is to compare if the other device is grabbed by the same
client, which should be checked by accessing (dev->deviceGrab->grab->resource).
A check of the server-1.3 sources confirms that.

XTS test case: Xlib13 XAllowEvents 20.

Peter Hutterer 9f462ff908 dix: Clip only into axis ranges if we're in absolute mode. (#26543)
An absolute device in relative mode may provide valuators outside of the
axis range. Clipping back into the range prevents screen crossings in a
multi-screen (Xinerama) setup as the required screen edge for crossing is
never met: miPointerSetPosition crosses the screen conditional to the X
coordinate being equal to the screen width or _less than_ 0. While the
former can be met when clipping into the coordinate range and scaling, the
latter cannot, resulting in a mouse pointer that gets stuck on the rightmost
screen.

This patch only applies axis clipping for valuators in mode Absolute. If
relative, we allow the values to get above/below the axis ranges. Doesn't
matter, miPointerSetPosition will reset the values to the allowed range even
if no screen was crossed.
This leads to interesting values provided to clients, the valuator range of
the device resets once a screen is crossed and essentially reflects
the position of the cursor on the screen - scaled into the valuator range.
The values themselves are valid given the range though.

In theory, the XI1 specs require that a relative device has a min/max range
of 0/0. This doesn't really go well with devices that actually can switch
mode between relative and absolute since they would have to reset their axis
range when switching. If multiple XI clients are in use, we have no method
of notifying them about the changes, so other clients may continue to use
the wrong axis ranges (note: XI1 wasn't really designed to have multiple
clients use a device). Expecting all relative devices to have this min/max
of 0 is unrealistic at this point.

So pick what is possibly the lesser of all evils, pass the beer and despair.

Evdev devices do not have the bell proc set, but XTEST devices do. By

sound. That's also XKB's behaviour if XkbUseCoreKbd is specified as device

Simon Thum 1763550d01 dix: add smooth limited pointer acceleration profile
This profile is inspired by the accel code removed from the wacom driver.
It ascends from zero to acceleration, maxing out at threshold. This means you
can control the slope using threshold, which wasn't possible in wacom.
For sanity's sake, threshold should grow with acceleration.

Works best with adaptive deceleration, since otherwise it only generates
acceleration above 1, causing seldom pixel skips.

Peter Hutterer 982f6648fd dix: increase default number of buttons to 10.
Currently the XTEST device is limited to the same number of buttons the core
device has. This breaks if a user has a mouse with more than 3 buttons
connected and is using a core client to fake button 8+ presses.

Rather than expecting all clients to fix themselves, just increase the
default number of buttons to 10, which is somewhat a compromise. Ideally,
the XTEST devices should adjust themselves to the highest number of buttons
available on the slave devices (like the master pointers already do), but
that's a taks for another day.

On 64-bit systems, int and pointers don't have the same size, so GCC gives
warnings about casts between int and pointer types. However, in the cases
covered by this patch, it's always a value that fits in int being stored
temporarily as a pointer and then converted back later, which is safe.
Casting through the pointer-sized integer type intptr_t convinces the
compiler that this is OK.
