hello,
when i use touchscreen to touch a titlebar or panel while an application
has a menu open xserver crashes.
i used gdb to narrow it down to a double free (FreeGrab is called twice
on the same grab) in /dix/events.c: DeactivatePointerGrab
DeactivatePointerGrab(DeviceIntPtr mouse)
{
GrabPtr grab = mouse->deviceGrab.grab;
DeviceIntPtr dev;
Bool wasPassive = mouse->deviceGrab.fromPassiveGrab;
Bool wasImplicit = (mouse->deviceGrab.fromPassiveGrab &&
mouse->deviceGrab.implicitGrab);
XID grab_resource = grab->resource;
int i;
/* If an explicit grab was deactivated, we must remove it from the
head of
* all the touches' listener lists. */
for (i = 0; !wasPassive && mouse->touch && i <
mouse->touch->num_touches; i++) {
TouchPointInfoPtr ti = mouse->touch->touches + i;
if (ti->active && TouchResourceIsOwner(ti, grab_resource)) {
int mode = XIRejectTouch;
/* Rejecting will generate a TouchEnd, but we must not
emulate a ButtonRelease here. So pretend the listener
already has the end event */
if (grab->grabtype == CORE || grab->grabtype == XI ||
!xi2mask_isset(mouse->deviceGrab.grab->xi2mask, mouse, XI_TouchBegin)) {
mode = XIAcceptTouch;
/* NOTE: we set the state here, but
* ProcessTouchOwnershipEvent() will still call
* TouchEmitTouchEnd for this listener. The other half of
* this hack is in DeliverTouchEndEvent */
ti->listeners[0].state = LISTENER_HAS_END;
}
>>>> TouchListenerAcceptReject(mouse, ti, 0, mode);
}
}
TouchRemovePointerGrab(mouse);
mouse->valuator->motionHintWindow = NullWindow;
mouse->deviceGrab.grab = NullGrab;
mouse->deviceGrab.sync.state = NOT_GRABBED;
mouse->deviceGrab.fromPassiveGrab = FALSE;
for (dev = inputInfo.devices; dev; dev = dev->next) {
if (dev->deviceGrab.sync.other == grab)
dev->deviceGrab.sync.other = NullGrab;
}
DoEnterLeaveEvents(mouse, mouse->id, grab->window,
mouse->spriteInfo->sprite->win, NotifyUngrab);
if (grab->confineTo)
ConfineCursorToWindow(mouse, GetCurrentRootWindow(mouse),
FALSE, FALSE);
PostNewCursor(mouse);
if (!wasImplicit && grab->grabtype == XI2)
ReattachToOldMaster(mouse);
ComputeFreezes();
>>FreeGrab(grab);
}
in one of the loop iterations TouchListenerAcceptReject() frees the grab
and allocates a new grab at mouse->deviceGrab.grab however grab is not
updated leading to a double free in FreeGrab(grab).
this is releated to https://gitlab.freedesktop.org/xorg/xserver/issues/625
attached are gdb logs of the double free. i also have detailed logs of
the crash etc if needed
