7c4fab2f1f render: Fix out of boundary heap access
ProcRenderCreateRadialGradient and ProcRenderCreateConicalGradient must
be protected against an integer overflow during length check. This is
already included in ProcRenderCreateLinearGradient since the fix for
CVE-2008-2362.

This can only be successfully exploited on a 32 bit system for an
out of boundary read later on. Validated by using ASAN.

18fcb66688 xwayland: Monitor client states to destroy callbacks
In XWayland, dri3_send_open_reply() is called from a sync callback, so
there is a possibility that the client might be gone when we get to the
callback eventually, which leads to a crash in _XSERVTransSendFd() from
WriteFdToClient() .

Client resources can survive the client itself, in which case we
may end up in our sync callback trying to access client's data after
it's been freed/reclaimed.

Add a ClientStateCallback handler to monitor the client state changes
and clear the sync callback set up by the glamor drm code if any.

d402b86b45 xwayland: clear cursor frame callback
After an X cursor is unrealized, the seat's corresponding x_cursor is
cleared, but if a frame callback was pending at the time, it will
remain and thus prevent any further cursor update, leaving the window
with no cursor.

Make sure to destroy the frame callback, if any, when that occurs, so
that next time a cursor needs to be set, it won't be ignored for a frame
callback that will never be triggered.

e4dd73b242 xwayland: do not set checkRepeat on master kbd
keyboard_check_repeat() fetches the XWayland seat from the
dev->public.devicePrivate do do its thing.

If a key event is sent programmatically through Xtest, our device is the
virtual core keyboard and that has a dev->public.devicePrivate of NULL,
leading to a segfault in keyboard_check_repeat().

This is the case with "antimicro" which sends key events based on the
joystick buttons.

Don't set the checkRepeat handler on the VCK since it cannot possibly work
anyway and it has no effect on the actual checkRepeat intended functionality.

c84f5c3dd1 xwayland: Make sure we have a focus window
During the InitInput() phase, the wayland events get dequeued so we
can possibly end up calling dispatch_pointer_motion_event().

If this occurs before xwl_seat->focus_window is set, it leads to a NULL
pointer derefence and a segfault.

Check for xwl_seat->focus_window in both pointer_handle_frame() and
relative_pointer_handle_relative_motion() prior to calling
dispatch_pointer_motion_event()  like it's done in
pointer_handle_motion().

e2243e5b80 glamor: Two pass won't work on memory pixmaps
When selecting "CA_TWO_PASS" in glamor_composite_clipped_region() when
the hardware does not support "GL_ARB_blend_func_extended", we call
glamor_composite_choose_shader() twice in a row, which in turn calls
glamor_pixmap_ensure_fbo().

On memory pixmaps, the first call will set the FBO and the second one
will fail an assertion in glamor_upload_picture_to_texture() because
the FBO is already set.

Bail out earlier when the mask pixmap is in memory and the hardware
capabilities would require to use two pass, so that the assertion is not
failed and the rendering is correct.

abf3bc68db xwayland: CRTC should support all rotations
If the Wayland compositor sets a rotation on the output, Xwayland
translates the transformation as an xrandr rotation for the given
output.

However, if the rotation is not supported by the CRTC, this is not
a valid setup and xrandr queries will fail.

Pretend we support all rotations and reflections so that the
configuration remains a valid xrandr setup.

fd74867b8b xwayland: Apply output rotation for screen size
Previously, we would swap the width/height of the Xwayland output based
on the output rotation, so that the overall screen size would match the
actual rotation of each output.

Problem is the RandR's ConstrainCursorHarder() handler will also apply
the output rotation, meaning that when the output is rotated, the
pointer will be constrained within the wrong dimension.

Moreover, XRandR assumes the original output width/height are unchanged
when the output is rotated, so by changing the Xwayland output width and
height based on rotation, Xwayland causes XRandr to report the wrong
output sizes (an output of size 1024x768 rotated left or right should
remain 1024x768, not 768x1024).

So to avoid this issue and keep things consistent between Wayland and
Xwayland outputs, leave the actual width/height unchanged but apply the
rotation when computing the screen size. This fixes both the output size
being wrong in "xrandr -q" and the pointer being constrained in the
wrong dimension with rotated with weston.

events during a timer function (wacom and synaptics do this during tap

something else to happen.

Fix this by simply returning 0 from check_timers if we ran at least one of
them or reset them all. This way the callers ospoll_wait will exit and

862c1c43c1 glamor: Trust eglGetPlatformDisplayEXT if it exists
If the libEGL we are using has eglGetPlatformDisplayEXT, yet it still
returns NULL, then this very likely means that it does not support the
type (e.g. EGL_PLATFORM_GBM_MESA) passed in, and then returning NULL is
the right thing to do.

This avoids falling back to an eglGetDisplay() implementation which does
not understands the passed in gbm handle, treats it as a pointer to
something else completely, followed by a crash sooner or later.

Specifically this fixes using the nvidia binary driver, with nvidia's
libEGL + the modesetting driver on a secondary GPU crashing inside
glamor_egl_init() sometimes.

8cf47472bf Fix a segfault that occurs if xorg.conf.d is absent:
In InitOutput, if xf86HandleConfigFile returns CONFIG_NOFILE
(which it does if no config file or directory is present), the
autoconfig flag is set, causing xf86AutoConfig to be called
later on.

xf86AutoConfig calls xf86OutputClassDriverList via the
call tree:

xf86AutoConfig =>
  listPossibleVideoDrivers =>
    xf86PlatformMatchDriver =>
      xf86OutputClassDriverList

and xf86OutputClassDriverList attempts to traverse a linked list
that is a member of the XF86ConfigRec struct pointed to by the
global xf86configptr, which is NULL at this point because the
XF86ConfigRec struct is only allocated (by xf86readConfigFile)
AFTER the config file and directory have been successfully
opened; the CONFIG_NOFILE return from xf86HandleConfigFile
occurs BEFORE the call to xf86readConfigFile which allocates
the XF86ConfigRec struct.

Rx: In read.c (for symmetry with xf86freeConfig, which already
appears in this file), add a new function xf86allocateConfig
which tests the value of xf86configptr and, if it's NULL,
allocates the XF86ConfigRec struct and deposits the pointer
in xf86configptr.  In xf86Parser.h, add a prototype for the
new xf86allocateConfig function.

Back in read.c, #include "xf86Config.h".  In xf86readConfigFile,
change the open-code call to calloc to a call to the new
xf86allocateConfig function.

In xf86AutoConfig.c, add a call to the new xf86allocateConfig function
to the beginning of xf86AutoConfig to make sure the XF86ConfigRec struct
is allocated.

make[6]: *** No rule to make target 'scripts/xvfb-piglit.sh', needed by 'scripts/xvfb-piglit.sh.log'.  Stop.
make[6]: Leaving directory '/home/pq/git/xserver/xorg-server-1.19.99.1/_build/sub/test'
Makefile:1367: recipe for target 'check-TESTS' failed

The setup to trigger this is:
  $ ./configure --prefix=/home/pq/local --disable-docs
  --disable-devel-docs --enable-xwayland --disable-xorg --disable-xvfb
  --disable-xnest --disable-xquartz --disable-xwin --enable-debug

SCRIPT_TESTS is populated conditionally, but we should distribute the
scripts in any case.

543287e60a composite: Fix repaint of borders (v2)
When going from border width zero to a non-zero border width, the
Composite extension is informed via the ConfigNotify callback. The
call-chain looks like this: compConfigNotify -> compReallocPixmap ->
compSetPixmap -> TraverseTree -> compSetPixmapVisitWindow. However, at
this time, pWindow->borderWidth was not yet updated. Thus, HasBorder()
is false and the window border will not be repainted.

To fix this, thread the new bw through to the window visitor, and
inspect that rather than HasBorder(). For the other callers of
compSetPixmap the border does not change size, so we can pass
pWin->borderWidth instead.

c24c9cc956 randr: rrCheckPixmapBounding: do not shrink the screen_pixmap
The purpose of rrCheckPixmapBounding is to make sure that the
screen_pixmap is *large* enough for the slave-output which crtc is
being configured.

However until now rrCheckPixmapBounding would also shrink the
screen_pixmap in certain scenarios leading to various problems.

For example: Take a laptop with its internalscreen on a slave-output and
currently disabled and an external monitor at 1920x1080+0+0.
Now lets say that we want to drive the external monitor at its native
resolution of 2560x1440 and have the internal screen mirror the top left
part of the external monitor, so we run:

  $ xrandr --output eDP --mode 1920x1080 --pos 0x0 --output HDMI \
  --mode 2560x1440 --pos 0x0

Here xrandr utility first calls RRSetScreenSize to 2560x1440, then it
calls RRSetCrtc 1920x1080+0+0 on the eDP, since this is a slave output,
rrCheckPixmapBounding gets called and resizes the screen_pixmap to
1920x1080, undoing the RRSetScreenSize. Then RRSetCrtc 2560x1440+0+0
gets called on the HDMI, depending on crtc->transforms this will
either result in a BadValue error from ProcRRSetCrtcConfig; or
it will succeed, but the monitor ends up running at 2560x1440
while showing a 1920x1080 screen_pixmap + black borders on the right
and bottom. Neither of which is what we want.

This commit removes the troublesome shrinking behavior, fixing this.

Note:

1) One could argue that this will leave us with a too large screen_pixmap
in some cases, but rrCheckPixmapBounding only gets called for slave
outputs, so xrandr clients already must manually shrink the screen_pixmap
after disabling crtcs in normal setups.

2) An alternative approach would be to also call rrCheckPixmapBounding
on RRSetCrtc on normal (non-slave) outputs, but that would result in
2 unnecessary resizes of the screen_pixmap in the above example, which
seems undesirable.

26132f57ee randr: rrCheckPixmapBounding: Do not substract crtc non 0 x,y from screen size
The purpose of rrCheckPixmapBounding is to make sure that the
screen_pixmap is large enough for the slave-output which crtc is
being configured.

This should include crtc->x and crtc->y, otherwise the crtc might
still end up scanning out an area outside of the screen-pixmap.

For example: Take a laptop with an external monitor on a slave-output at
1920x1080+0+0 and its internal-screen at 3840x2160+1920+0 and in
gnome-settings-daemon move the external monitor to be on the ri ght of
the internal screen rather then on the left. First g-s-d will do a
RRSetScreenSize to 5760*2160 (which is a nop), then it calls RRSetCrtc
to move the slave output to 1920x1080+3840+0, since this is a slave
output, rrCheckPixmapBounding gets called, since the 2 crtcs now overlap
the code before this commit would shrinks the screen_pixmap to 3180*2160.
Then g-s-d calls RRSetCrtc to move the internal screen to 3180*2160+0+0.

And we end up with the slave-output configured to scan-out an area
which completely falls outside of the screen-pixmap (and end up with
a black display on the external monitor).

This commit fixes this by not substracting the x1 and y1 coordinates
of the union-ed region when determining the new screen_pixmap size.

6c51845e6b xwayland: Fix use after free of cursors
Sometimes, Xwayland will try to use a cursor that has just been freed,
leading to a crash when trying to access that cursor data either in
miPointerUpdateSprite() or AnimCurTimerNotify().

CheckMotion() updates the pointer's cursor based on which xwindow
XYToWindow() returns, and Xwayland implements its own xwl_xy_to_window()
to fake a crossing to the root window when the pointer has left the
Wayland surface but is still within the xwindow.

But after an xwindow is unrealized, the last xwindow used to match the
xwindows is cleared so two consecutive calls to xwl_xy_to_window() may
not return the same xwindow.

To avoid this issue, update the last_xwindow based on enter and leave
notifications instead of xwl_xy_to_window(), and check if the xwindow
found by the regular miXYToWindow() is a child of the known last
xwindow, so that multiple consecutive calls to xwl_xy_to_window()
return the same xwindow, being either the one found by miXYToWindow()
or the root window.

b711efb057 glamor: restore vfunc handlers on init failure
In glamor_init(), if the minimum requirements are not met, glamor may
fail after setting up its own CloseScreen() and DestroyPixmap()
routines, leading to a crash when either of the two routines is called
if glamor failed to complete its initialization, e.g:

  (EE) Backtrace:
  (EE) 0:  Xwayland (OsSigHandler+0x29)
  (EE) 1: /lib64/libpthread.so.0 (__restore_rt+0x0)
  (EE) 2: Xwayland (glamor_sync_close+0x2a)
  (EE) 3: Xwayland (glamor_close_screen+0x52)
  (EE) 4: Xwayland (CursorCloseScreen+0x88)
  (EE) 5: Xwayland (AnimCurCloseScreen+0xa4)
  (EE) 6: Xwayland (present_close_screen+0x42)
  (EE) 7: Xwayland (dix_main+0x4f9)
  (EE) 8: /lib64/libc.so.6 (__libc_start_main+0xf1)
  (EE) 9:  Xwayland (_start+0x2a)

Restore the previous CloseScreen() and DestroyPixmap() vfunc handlers in
case of failure when checking for the minimum requirements, so that if
any of the requirement is not met we don't leave the CloseScreen() and
DestroyPixmap() from glamor handlers in place.

738c17b7ef xwayland: Don't send KeyRelease events on wl_keyboard::leave
Commits 816015648f and
fee0827a9a made it so that
wl_keyboard::enter doesn't result in X clients getting KeyPress events
while still updating our internal xkb state to be in sync with the
host compositor.

wl_keyboard::leave needs to be handled in the same way as its
semantics from an X client POV should be the same as an X grab getting
triggered, i.e. X clients shouldn't get KeyRelease events for keys
that are still down at that point.

This patch uses LeaveNotify for these events on wl_keyboard::leave and
changes the current use of KeymapNotify to EnterNotify instead just to
keep some symmetry between both cases.

On ProcessDeviceEvent() we still need to deactivate X grabs if needed
for KeyReleases.
