A new --with-fallback-input-driver=foo option allows selecting a
fallback driver for the server if the driver configured for the device
is not found. Note that this only applies when the device has a driver
assigned and that module fails to load, devices without a driver are
ignored as usual.
This avoids the situation where a configuration assigns e.g. the
synaptics driver but that driver is not available on the system,
resulting in a dead device. A fallback driver can at least provides some
functionality.
This becomes more important as we move towards making other driver true
leaf nodes that can be installed/uninstalled as requested. Specifically,
wacom and synaptics, a config that assigns either driver should be
viable even when the driver itself is not (yet) installed on the system.
It is up to the distributions to make sure that the fallback driver is
always installed. The fallback driver can be disabled with
--without-fallback-input-driver and is disabled by default on non-Linux
systems because we don't have generic drivers on those platforms.
Default driver on Linux is libinput, evdev is the only other serious

issues since it may happen that a timestamp from CLOCK_MONOTONIC
retrieved before a sending an X request will still be "later" than the
timestamp the X server than gets after receiving the request, due to the
fact that CLOCK_MONOTONIC_COARSE has a lower resolution.
To avoid these issues, make Xwayland always use CLOCK_MONOTONIC, so

When NumLock is on and a new keymap is applied, the next modifier state
change will turn off that LED (but leave the state enabled). The cause
for this is a bit convoluted:
* the SLI explicitState is copied from the current state in
ProcXkbGetKbdByName. Thus, if NumLock is on, that state is 0x2.
* on the next modifier key press (e.g. Shift), XkbApplyState() calls into
XkbUpdateIndicators() -> XkbUpdateLedAutoState() to update SLIs (if any)
for the currently changed modifier. But it does so with a mask only for
the changed modifier (i.e. for Shift).
* XkbUpdateLedAutoState() calculates the state based on this mask and
ends up with 0 because we don't have a Shift LED and we masked out the
others.
* XkbUpdateLedAutoState() compares that state with the previous state
(which is still 0x2) and then proceeds to turn the LED off
This doesn't happen in the normal case because either the mask
encompasses all modifiers or the state matches of the masked-out
modifiers matches the old state.
Avoid this issue by forcing an SLI update after changing the keymap.
This updates the sli->effectiveState and thus restores everything to
happy working order.

216bdbc735 removed the SetRootClip call in the XWayland output-hotplug
handler when running rootless (e.g. as a part of Weston/Mutter), since
the root window has no storage, so generating exposures will result in
writes to invalid memory.
Unfortunately, preventing the segfault also breaks sprite confinement.
SetRootClip updates winSize and borderSize for the root window, which
when combined with RRScreenSizeChanged calling ScreenRestructured,
generates a new sprite-confinment area to update it to the whole screen.
Removing this call results in the window geometry being reported
correctly, but winSize/borderSize never changing from their values at
startup, i.e. out of sync with the root window geometry / screen
information in the connection info / XRandR.
This patch introduces a hybrid mode, where we update winSize and
borderSize for the root window, enabling sprite confinement to work
correctly, but keep the clip emptied so exposures are never generated.

To ease integration add this as a second set to the ValuatorMask rather than
extending all APIs to carry a second, possibly NULL set of valuators.
Note that a valuator mask should only be used in either accel/unaccel or
standard mode at any time. Switching requires either a valuator_mask_zero()
call or unsetting all valuators one-by-one. Trying to mix the two will produce
a warning.
The server has a shortcut for changing a mask with the
valuator_mask_drop_unaccelerated() call. This saves us from having to loop
through all valuators on every event, we can just drop the bits we know we
don't want.

Besides that oom is something which should simply never happen, so aborting

With the recent systemd-logind changes it is possible to install the Xorg
binary without suid root rights and still have everything working as it
should *if* the user only has cards which are supported by kms.
This commit adds a little suid root wrapper, which is a bit weird, first we
strip the suid-root bit of the Xorg binary, and then we add a wrapper ?
The function of this wrapper is to see if a system still needs root-rights,
if it does not (it supports kms and the kms drivers are properly loaded),
then it will immediately drop all elevated rights before executing the real
Xorg binary. If it finds (some) cards which don't support kms, or no cards
at all, then it will execute the Xorg server with elevated rights so that
ie the nvidia binary driver and the vesa driver can keep working normally.
To make it possible for security concious users who don't need the root
rights to completely remove the wrapper, Xorg is started in a 3 step process
when the wrapper is enabled during build time:
1) A simple shell script which checks if the wrapper is there, if it is
it executes the wrapper, if not it directly executes the real Xorg binary
2) The wrapper gets executed, does its checks, normally drops all elevated
rights and then executes the real Xorg binary
3) The real Xorg binary does its thing
This allows distributions to put the wrapper binary in a separate package, and
will allow users to remove this package. IE the plan with Fedora is to make
"legacy" drivers depend on the wrapper pkg, and since our default install
contains some legacy drivers it will be part of the default install, but
users can later yum remove it (which will also automatically remove the
legacy driver packages as those won't work without it anyways).
The wrapper is loosely modelled after the existing Debian Xwrapper, it
uses the same config-file + config-file format, and also allows restricting
Xserver execution (through the wrapper) to console users only.
There also is a new needs_root_rights config file directive, which can
be used to override the auto-detection the wrapper does.
Hopefully this will allow Debian to replace their own wrapper with this
upstream one.

Since 4bc2761 activeGrab is a pointer itself and points to the same memory
as grabinfo->grab, leaving us with the potential of dangling pointers if
either calls FreeGrab() and doesn't reset the other one.
There is no reader of activeGrab anyway, so simply removing it is
sufficient.

A sync grab is the owner once it gets events. If it doesn't replay the
event it will get all events from this touch, equivalent to accepting it.
If the touch has ended before XAllowEvents() is called, we also now need to

Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
If a device is frozen in results to a grab, we need to enqueue the events.
This makes things complicated, and hard to follow since touch events are now
replayed in the history, pushed into EnqueueEvent, then replayed later
during PlayReleasedEvents in response to an XAllowEvents.
While the device is frozen, no touch events are processed, so if there is a
touch client with ownership mask _below_ the grab this will delay the
delivery and potentially screw gesture recognition. However, this is the
behaviour we have already anyway if the top-most client is a sync pgrab or
there is a sync grab active on the device when the TouchBegin was generated.
(also note, such a client would only reliably work in case of ReplayPointer
anyway)

disabled cursor display a priori unless -retro is given.
On a plain server, caling XFixesHideCursor() and XFixesShowCursor() would
show the default root cursor, despite no client actually defining a cursor.
Change the logic, disable CursorVisible by default and only enable it from
the window's CWCursor logic. If no window ever defines a cursor, said cursor
stays invisible.

If we're about to abort, we're already in the signal handler and cannot call
down to the default device cleanup routines (which reset, free, alloc, and
do a bunch of other things).
Add a new DEVICE_ABORT mode to signal a driver's DeviceProc that it must
reset the hardware if needed but do nothing else. An actual HW reset is only
required for some drivers dealing with the HW directly.
This is largely backwards-compatible, hence the input ABI minor bump only.
Drivers we care about either return BadValue on a mode that's not
DEVICE_{INIT|ON|OFF|CLOSE} or print an error and return BadValue. Exception
here is vmmouse, which currently ignores it and would not reset anything.
This should be fixed if the reset is required.

The transformation matrix we previously stored was a scaled matrix based on
the axis ranges of the device. For relative movements, the scaling is not
required (or desired).
Store two separate matrices, one as requested by the client, one as the
product of [scale . matrix . inv_scale]. Depending on the type of movement,
apply the respective matrix.
For relative movements, also drop the translation component since it doesn't
really make sense to use that bit.

For absolute events, if the client specifies a screen number offset the
coordinates by that. And add a new flag so we know when _not_ to add the
screen offset in GPE.
Without this offset and the flag, GPE would simply add the offset of the
current screen if POINTER_SCREEN is set.

RELOCATE_PROJECTROOT is AC_DEFINED in configure.ac, but currently has no effect
as it doesn't appear in any AC_CONFIG_HEADER header.
When packaged for Windows, we do not have a unix-style filesystem tree, where
file needed by the X server can be found in fixed, absolute paths under the
prefix (PROJECTROOT).
Instead, the filesystem tree containing files needed by the X server and clients
will be installed with the directory containing the X server executable as the
root directory of that tree.
(Typically, this will be in the Program Files directory, which does not have a
fixed name, as it can be moved, localized, or added to to indicate x86 or x64
binaries)
So, RELOCATE_PROJECTROOT is used to make a native Windows build of the X server
look for various files (fonts, xkb data) in locations relative to the X server
rather than at absolute paths, by translating those paths at run-time.
Additionally the XKEYSYMDB, XERRORDB, XLOCALEDIR env vars checked by libX11 are
set appropriately for clients started by the X server.

This places a pointer to the grab related to a TouchListener directly
in the TouchListener structure rather than hoping to find the grab
later on using the resource ID.
Passive grabs have resource ID in the resource DB so they can be
removed when a client exits, and those resource IDs get copied when
activated, but implicit grabs are constructed on-the-fly and have no
resource DB entry.

Commit 31bf81772e changed the clientState field
from a signed int to a signed int 2-bit bitfield. The ClientState enum that is
expected to be assigned to this field has four values: ClientStateInitial (0),
ClientStateRunning (1), ClientStateRetained (2), and ClientStateGone (3).
However, because this bitfield is signed, ClientStateRetained becomes -2 when
assigned, and ClientStateGone becomes -1. This causes warnings:
test.c:54:10: error: case label value exceeds maximum value for type [-Werror]
test.c:55:10: error: case label value exceeds maximum value for type [-Werror]
The code here is a switch statement:
53 switch (client->clientState) {
54 case ClientStateGone:
55 case ClientStateRetained:
56 [...]
57 break;
58
59 default:
60 [...]
61 break;
62 }
It also causes bizarre problems like this:
client->clientState = ClientStateGone;
assert(client->clientState == ClientStateGone); // this assert fails
Also change the signedness of nearby bitfields to match.
