e957a2e5dd dix: Add hybrid full-size/empty-clip mode to SetRootClip
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.

Previously all X servers started with -displayfd would overwrite
Xorg.0.log - now a temporary name of Xorg.pid-<pid>.log is used

0c41b7af4a os: Add NotifyFd interfaces
This provides a callback-based interface to monitor file
descriptors beyond the usual client and device interfaces.

Modules within the server using file descriptors for reading and/or
writing can call

    Bool SetNotifyFd(int fd, NotifyFdProcPtr notify_fd, int mask, void *data);

mask can be any combination of X_NOTIFY_READ and X_NOTIFY_WRITE.

When 'fd' becomes readable or writable, the notify_fd function will be
called with the 'fd', the ready conditions and 'data' values as arguments,

When the module no longer needs to monitor the fd, it will call

    void RemoveNotifyFd(int fd);

RemoveNotifyFd may be called from the notify function.

Commit 4b4b9086 "os: support new implicit local user access mode [CVE-2015-3164

but unfortunately doesn't notice that NO_LOCAL_CLIENT_CRED is defined as a

precede its definition.

Move the check if NO_LOCAL_CLIENT_CRED should be defined to configure.ac, so it
always occurs before it's first use.

v2:
Move check to configure.ac

v3:
Use AC_CACHE_CHECK and name cache varaible appropriately

d206c240c0 configurable maximum number of clients
Make the maximum number of clients user configurable, either from the command
line or from xorg.conf

This patch works by using the MAXCLIENTS (raised to 512) as the maximum
allowed number of clients, but allowing the actual limit to be set by the
user to a lower value (keeping the default of 256).

There is a limit size of 29 bits to be used to store both the client ID and
the X resources ID, so by reducing the number of clients allowed to connect to
the X server, the user can increase the number of X resources per client or
vice-versa.

Parts of this patch are based on a similar patch from Adam Jackson

90db5edf11 prime: add rotation support for offloaded outputs (v2)
One of the lacking features with output offloading was
that screen rotation didn't work at all.

This patch makes 0/90/180/270 rotation work with USB output
and GPU outputs.

When it allocates the shared pixmap it allocates it rotated,
and any updates to the shared pixmap are done using a composite
path that does the rotation. The slave GPU then doesn't need
to know about the rotation and just displays the pixmap.

v2:
rewrite the sync dirty helper to use the dst pixmap, and
avoid any strange hobbits and rotations.

This breaks ABI in two places.

4b4b9086d0 os: support new implicit local user access mode [CVE-2015-3164 2/3]
If the X server is started without a '-auth' argument, then
it gets started wide open to all local users on the system.

This isn't a great default access model, but changing it in
Xorg at this point would break backward compatibility.

Xwayland, on the other hand is new, and much more targeted
in scope.  It could, in theory, be changed to allow the much
more secure default of a "user who started X server can connect
clients to that server."

This commit paves the way for that change, by adding a mechanism
for DDXs to opt-in to that behavior.  They merely need to call

LocalAccessScopeUser()

in their init functions.

A subsequent commit will add that call for Xwayland.

4c2f2cb4c8 dix: Add unaccelerated valuators to the ValuatorMask
Allows a mask to carry both accelerated and unaccelerated motion at the same
time.

This is required for xf86-input-libinput where the pointer acceleration
happens in libinput already, but parts of the server, specifically raw events
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
don't want.

Multiple functions in the Xinput extension handling of requests from
clients failed to check that the length of the request sent by the
client was large enough to perform all the required operations and
thus could read or write to memory outside the bounds of the request
buffer.

This commit includes the creation of a new REQUEST_AT_LEAST_EXTRA_SIZE
macro in include/dix.h for the common case of needing to ensure a
request is large enough to include both the request itself and a
minimum amount of extra data following the request header.

da887726ee Use unique display name for each xi2 test program [v3]
make -j 8 check was sporadically failing in different xi2 tests.
After adding the asserts in the previous commit to catch xkb failure
it became easier to catch the failures and see that multiple tests
were running at once trying to write to /tmp/server-(null).xkm and
then delete it, and interfering with each other.

Putting a unique string into the display variable let them each write
to their own file and not interfere with others.

v2: Fix Linux bits:

  Add #include <errno.h> to get a declaration of
  program_invocation_name on Linux.

  Use only the last portion of the pathname so that the resulting
  display name doesn't contain any slashes.

v3: use program_invocation_short_name on Linux

  This is the same as program_invocation_name, except is has
  stripped off any path prefix.

We can only request one fd per device from systemd-logind. If a fd is re-used
by the same device, releasing the fd from one device doesn't mean we can close
it. The systemd code knows when it's really released, so let it close the fd.

Test case: xorg.conf section for an input device with hotplugging enabled.
evdev detects the duplicate and closes the hotplugged device, which closes the
fd. The other instance of evdev thinks the fd is still valid so now you're
playing a double lottery. First, which client(s) will get the evdev fd?
Second, which requests will be picked up by evdev and which ones will be
picked up by the client? You'll never know, but the fun is in finding out.
