3ea7d271c8 os: Return BadLength instead of disconnecting BigReq clients (#4565)
If a client sends a big request that's too big (i.e. bigger than
maxBigRequestSize << 2 bytes), the server just disconnects it.  This makes the
client receive SIGPIPE the next time it tries to send something.

The X Test Suite sends requests that are too big when the test specifies the
TOO_LONG test type.  When the client receives SIGPIPE, XTS marks it as
UNRESOLVED, which counts as a failure.

Instead, remember how long the request is supposed to be and then return that
size.  Dispatch() checks the length and sends BadLength to the client.  Then,
whenever oci->ignoreBytes is nonzero, ignore the data read instead of trying to
process it as a request.

57d4547589 linux: Don't lose console events on non-evdev drivers (#29969)
The drain_console() function will race with new keyboard events being added
by the hardware causing the server to lose keyboard events if the console fd
is used for input.

Only use the drain_console() when AllowEmptyInput is off which is the best
indicator we have for whether the keyboard driver will be used. This patch
will only fix the bug when hotplugging is disabled.
What we really need is a way to figure out either whether we're _not_ using
the keyboard driver (not predictable) or a way for the keyboard driver to
disable drain_console().

72e3e6f4a7 dix: fix crash when removing devices on a buttonless MD pointer (#29669)
If the master does not have a button class, recalculating the number of
buttons required for this master dereferences a NULL pointer. Guard against
this, if the master pointer doesn't have a button class, it doesn't need to
update it's number of buttons.

Reproducible:
Two devices on the same master, device NB with axes but no buttons, device
A+B with axes and button .
If NB was the last one to send an event through the master when A+B is
removed from the server, master->button is NULL and leads to the above
NULL-pointer dereference.

0f3a0ab1f0 Fix udev population of Bluetooth input device product IDs
The udev device_added function takes the vendor and model IDs of added
devices and converts them into an attribute that can be matched for by
an InputClass configuration using MatchUSBID. Currently, the udev
mechanism works for USB devices, but fails to work properly for
Bluetooth devices. The product IDs of the event node are actually the
IDs of the Bluetooth receiver instead of the device.

This patch reads the product ID from the PRODUCT property of the parent
of the added device. This tag is set correctly for both USB and
Bluetooth input devices. The following devices have been tested by
specifying individual InputClass sections in xorg.conf:

* Apple Keyboard (Bluetooth)
* Apple Magic Trackpad (Bluetooth)
* Apple Magic Mouse (Bluetooth)
* Microsoft Bluetooth Notebook Mouse 5000 (Bluetooth)
* Microsoft IntelliMouse Optical (USB)
* N-Trig Touchscreen (USB)
* Wacom Bamboo Touch (USB)

3e56efcfb6 fb: make isClipped always reject negative coordinates (bug 11503)
A window with either dimension > 32767 can be positioned such that
coordinates > 32767 are visible on the screen. Attempts to draw to
those pixels will generate coordinates wrapped around to negative
values.

The optimized clipping macro, 'isClipped', in fbbits.h, computes
clipping in window space rather than screen space using int16 values,
and so it too has coordinates wrapped around to negative values and
hence ends up accepting the wrapped drawing coordinates.

Two possible fixes for this problem

 1) Detect wrapped region coordinates and clip those to 32767.
 2) Detect negative incoming coordinates and reject those

This patch takes the second approach as it is much shorter, simply
detecting when either X or Y incoming coordinate is negative, which
can never be 'within' any drawable.

951605b466 edid: Adjust rounding of max_clock
A simple hack to accommodate various EDID who have detailed modes that
exceed the EDID's max pixel clock. The pixel clock is only defined in
units of 10MHz and often appears as the maximum pixel code of the
detailed modes, rounded to the nearest 10MHz. Adjusting the max_clock to
include an extra 5MHz prevents the parser from rejecting the detailed
modes.

The kernel uses the same fuzz and by including it in X we can use the
same modes in X as for the console.

Fixes:

  Bug 23833 - X uses different refresh rate to that set by kernel module
  https://bugs.freedesktop.org/show_bug.cgi?id=23833

In the future, we will want to try harder to keep the KMS modes but at
the same time we need to apply the restrictions as specified by the
user's configuration, and need to fill in modes for fullscreen games on
fixed-mode panels.

After copying the unused_classes into the device, reset the original
pointer. Otherwise we have two pointers pointing to the same field and both
get freed on device removal.

Some classes already have this behaviour since 51c8fd69.

1a172f3297 xkb: if the button isn't down, don't fake an event.
If the button we're about to fake isn't down (or up), don't fake a release
(or press) event for it. Behaviour is the same as before, this just saves
a few cycles.

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.

6dae7f3792 xace: Invalid reference to out-of-scope data.
The callback data passed by reference to the hook was allocated on stack
within the scope of the case statement. The compiler is free to reuse
any of that stack space whilst making the function call so we may end up
passing garbage into the callback.

ff70848e62 Don't let alpha maps recurse in fb. Bug 23581.
Recursive alpha maps (where one picture's alpha map is set to a
picture with an external alpha map) would be all fine and dandy,
except for the case where the client constructs a loop. Detecting this
case when setting the alpha map values would be difficult as any time
an alpha map is set, the server would have to check for the looping
case.

Instead, a far simpler fix is to simply disallow recursive alpha maps
in the rendering code, the Render spec is ambiguous in this area and
allows us to to ignore the recursive case.

70a94c5b7a rootless: fix uninitialized private key assert in non-rootless modes in Cygwin/X
IsFramedWindow() is called from miPaintWindow() if the server has
been built with ROOTLESS defined, irrespective of if RootlessInit()
has ever been called, or not.

Add a check to IsFramedWindow() to check if rootlessWindowPrivateKey
has been registered (as a proxy for checking if the rootless extension
has been initialized) so we don't go on to try to use that key,
triggering an assert.

This bug exposes what appears to be a difference in opinion about
the rootless extension between XQuartz and XWin.  XQuartz always
initializes the rootless extension, whereas XWin offers several modes
of operation, and the rootless extension is only used for one of them

That probably means that the all code under compile time guard for
ROOTLESS should be carefully checked that it doesn't also need to be
under a run-time guard

(I've reviewed the other ROOTLESS blocks in dix/events.c and
dix/window.c and they look ok -- keithp)

3ab6cd31cb fonts: Fix refcounting for asynchronous font operations (#3040)
When doing Xinerama, we'll dispatch font ops across all backend screens.
If using a font server (such that some operations can sleep), we'll put
the client to sleep once for each screen, but only wake up once, because
we're trying to keep track of the sleep count in _each_ screen's
closure.

Instead, just ask the core whether the client is already asleep.
