This add a new flag POINTER_RAWONLY for GetPointerEvents() which does
pretty much the opposite of POINTER_NORAW.
Basically, this tells GetPointerEvents() that we only want the
DeviceChanged events and any raw events for this motion but no actual
motion events.
This is preliminary work for Xwayland to be able to use relative motion
events for raw events. Xwayland would use absolute events for raw
events, but some X11 clients (wrongly) assume raw events to be always
relative.
To allow such clients to work with Xwayland, it needs to switch to
relative raw events (if those are available from the Wayland
compositor).
However, Xwayland cannot use relative motion events for actual pointer
location because that would cause a drift over time, the pointer being
actually controlled by the Wayland compositor.
So Xwayland needs to be able to send only relative raw events, hence
this API.
Bump the ABI_XINPUT_VERSION minor version to reflect that API addition.

Request-handlers as registered in the requestVector array, always get
passed the clientPtr for the client which sent the request.
But the implementation of many request-handlers typically consists of
a generic handler calling implementation specific callbacks and / or
various helpers often multiple levels deep and in many cases the clientPtr
does not get passed to the callbacks / helpers.
This means that in some places where we would like to have access to the
current-client, we cannot easily access it and fixing this would require
a lot of work and often would involve ABI breakage.
This commit adds a GetCurrentClient helper which can be used as a
shortcut to get access to the clienPtr for the currently being processed
request without needing a lot of refactoring and ABI breakage.
Note using this new GetCurrentClient helper is only safe for code
which only runs from the main thread, this new variable MUST NOT be used
by code which runs from signal handlers or from the input-thread.
The specific use-case which resulted in the creation of this patch is adding
support for emulation of randr / vidmode resolution changes to Xwayland.
This emulation will not actually change the monitor resolution instead it
will scale any window with a size which exactly matches the requested
resolution to fill the entire monitor. The main use-case for this is
games which are hard-coded to render at a specific resolution and have
sofar relied on randr / vidmode to change the monitor resolution when going
fullscreen.
To make this emulation as robust as possible (e.g. avoid accidentally scaling
windows from other apps) we want to make the emulated resolution a per client
state. But e.g. the RRSetCrtc function does not take a client pointer; and is
a (used) part of the Xorg server ABI (note the problem is not just limited
to RRSetCrtc).

Differences from autotools:
* Autotools defined NO_ALLOCA for OSX builds. I don't think we need
this anymore as Xalloc.h is no longer used anywhere in the xserver.
* X11.bin is linked with -u,miDCInitialize, and then libserver_mi
provided to satisfy (just) that. It's been that way since the commit
which added it. We can't write the equivalent in meson due to linker
argument ordering issues, but do we really need to?
* An explicit -Dsecure-rpc=false is required for OSX, since in meson we
don't do the checks that XTRANS_SECURE_RPC_FLAGS did for the existence
of the specific RPC functions required.

The autoconf build hard-codes XCONFIGFILE to just 'xorg.conf':

Later, the X server passes that into DoSubstitution() which expands the path:
DoSubstitution(template="/etc/X11/%X", ..., XConfigFile="xorg.conf")
This returns "/etc/X11/xorg.conf".
The Meson build, on the other hand, sets XCONFIGFILE to
join_paths(get_option('sysconfdir'), 'xorg.conf'). If sysconfdir is /etc, this

This adds initial support for displaying Xwayland applications through
the use of EGLStreams and nvidia's custom wayland protocol by adding
another egl_backend driver. This also adds some additional egl_backend
hooks that are required to make things work properly.
EGLStreams work a lot differently then the traditional way of handling
buffers with wayland. Unfortunately, there are also a LOT of various
pitfalls baked into it's design that need to be explained.
This has a very large and unfortunate implication: direct rendering is,
for the time being at least, impossible to do through EGLStreams. The
main reason being that the EGLStream spec mandates that we lose the
entire color buffer contents with each eglSwapBuffers(), which goes
against X's requirement of not losing data with pixmaps. no way to use
an allocated EGLSurface as the storage for glamor rendering like we do
with GBM, we have to rely on blitting each pixmap to it's respective
EGLSurface producer each frame. In order to pull this off, we add two
different additional egl_backend hooks that GBM opts out of
implementing:
- egl_backend.allow_commits for holding off displaying any EGLStream
backed pixmaps until the point where it's stream is completely
initialized and ready for use
- egl_backend.post_damage for blitting the content of the EGLStream
surface producer before Xwayland actually damages and commits the
wl_surface to the screen.
The other big pitfall here is that using nvidia's wayland-eglstreams
helper library is also not possible for the most part. All of it's API
for creating and destroying streams rely on being able to perform a
roundtrip in order to bring each stream to completion since the wayland
compositor must perform it's job of connecting a consumer to each
EGLstream. Because Xwayland has to potentially handle both responding to
the wayland compositor and it's own X clients, the situation of the
wayland compositor being one of our X clients must be considered. If we
perform a roundtrip with the Wayland compositor, it's possible that the
wayland compositor might currently be connected to us as an X client and
thus hang while both Xwayland and the wayland compositor await responses
from eachother. To avoid this, we work directly with the wayland
protocol and use wl_display_sync() events along with release() events to
set up and destroy EGLStreams asynchronously alongside handling X
clients.
Additionally, since setting up EGLStreams is not an atomic operation we
have to take into consideration the fact that an EGLStream can
potentially be created in response to a window resize, then immediately
deleted due to another pending window resize in the same X client's
pending reqests before Xwayland hits the part of it's event loop where
we read from the wayland compositor. To make this even more painful, we
also have to take into consideration that since EGLStreams are not
atomic that it's possible we could delete wayland resources for an
EGLStream before the compositor even finishes using them and thus run
into errors. So, we use quite a bit of tracking logic to keep EGLStream
objects alive until we know the compositor isn't using them (even if
this means the stream outlives the pixmap it backed).
While the default backend for glamor remains GBM, this patch exists for
users who have had to deal with the reprecussion of their GPU
manufacturers ignoring the advice of upstream and the standardization of
GBM across most major GPU manufacturers. It is not intended to be a
final solution to the GBM debate, but merely a baindaid so our users
don't have to suffer from the consequences of companies avoiding working
upstream. New drivers are strongly encouraged not to use this as a
backend, and use GBM like everyone else. We even spit this out as an
error from Xwayland when using the eglstream backend.

while it's current, we allocate a fake ID for the context and move the
context state there, so the tag data still points to a real context. As
a result we can stop trying so hard to detach the client from contexts
at disconnect time and just let resource destruction handle it.
Since vnd handles all the MakeCurrent protocol now, our request handlers
for it can just be return BadImplementation. We also remove a bunch of
LEGAL_NEW_RESOURCE, because now by the time we're called vnd has already
allocated its tracking resource on that XID.
v2: Update to match v2 of the vnd import, and remove more redundant work

Now that we can actually configure all of the directories xkb uses for
finding things, we can (finally, but only with meson) finally make it so
that with the correct meson configuration the Xserver will "just work"
without any additional changes to the installation prefix after
building.
For the people like me who have since scripted this part out of their
build process and forgotten about it, building and installing the X
server into a non-standard prefix has always required the following (or
something else that makes sure that X has a valid xkbcomp configuration)
commands be run right after doing the installation:
# start in root of prefix you installed X to
mkdir -pv share/X11/xkb/rules
ln -s /usr/share/X11/xkb/rules/evdev share/X11/xkb/rules/
rm -f bin/xkbcomp
ln -s /usr/bin/xkbcomp bin/
The one last piece of getting rid of this post-install junk is making
sure that we can control the directory that X uses for finding the
xkbcomp binary from meson so we can point it at the system provided
xkbcomp (/usr/bin/xkbcomp or similar). So, this patch adds a
configuration option for controlling this called xkb_bin_dir.

Special case for the systemd-logind case in xfree86: when we're vt-switched
away and a device is plugged in, we get a paused fd from logind. Since we
can't probe the device or do anything with it, we store that device in the
xfree86 and handle it later when we vt-switch back. The device is not added to
inputInfo.devices until that time.
When the device is removed while still vt-switched away, the the config system
never notifies the DDX. It only runs through inputInfo.devices and our device
was never added to that.
When a device is plugged in, removed, and plugged in again while vt-switched
away, we have two entries in the xfree86-specific list that refer to the same
device node, both pending for addition later. On VT switch back, the first one
(the already removed one) will be added successfully, the second one (the
still plugged-in one) fails. Since the fd is correct, the device works until
it is removed again. The removed devices' config_info (i.e. the syspath)
doesn't match the actual device we addded tough (the input number increases
with each plug), it doesn't get removed, the fd remains open and we lose track
of the fd count. Plugging the device in again leads to a dead device.
Fix this by adding a call to notify the DDX to purge any remainders of devices
with the given config_info, that's the only identifiable bit we have at this
point.

- a query to map a fbconfigID to a native pixelformatindex

Windows-DRI can only be useful if we are using WGL, so make an note if WGL

That enables factoring out the deferred drawable creation code as

Enhance glxWinDeferredCreateDrawable(), so that pixmaps are placed into a

Currently, this file mapping is accessed by a name generated from the XID.
This will not be unique across multiple server instances. It would perhaps

This commit fixes this by unifying all 3 lists into a single slaves list.

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
candidate here.

By default the X server will try CLOCK_MONOTONIC_COARSE before
CLOCK_MONOTONIC, while A Wayland compositor may only support getting
their timestamps from the CLOCK_MONOTONIC clock. This causes various
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
that it becomes possible for Wayland compositor only supporting
CLOCK_MONOTONIC and X server to use the same clock.

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.

will set ATTR_KEY, but not ATTR_KEYBOARD, for non-keyboard key input

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.

This is required for xf86-input-libinput where the pointer acceleration

and DGA rely on device-specific unaccelerated data.
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

Multiple functions in the Xinput extension handling of requests from
clients failed to check that the length of the request sent by the

thus could read or write to memory outside the bounds of the request

This commit includes the creation of a new REQUEST_AT_LEAST_EXTRA_SIZE

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.
