This prevents autotools to try to rebuild themselve automagically
if configure.ac, Makefile.am or a few other have more recent time
stamps than the generated files.
It will allows to get rid of the NO_REORDER mechanism that touches
files in the source tree to ensure nothing gets rebuilt.
of the makekeys util. This means it's also rebuilt during install. First
as root during build, later by the BUILDUSER during release, which won't
be able to rewrite it, because it's now owned by root. With this result:

One step closer towards noperm release builds for xenocara.

If an empty string is received from an x-server, do not underrun the
buffer by accessing "rep.nameLen - 1" unconditionally, which could end
up being -1.
From Tobias Stoeckmann / X.Org security advisory Oct 4, 2016
The Xv query functions for adaptors and encodings suffer from out of boundary
accesses if a hostile X server sends a maliciously crafted response.
A previous fix already checks the received length against fixed values but
ignores additional length specifications which are stored inside the received
data.
These lengths are accessed in a for-loop. The easiest way to guarantee a
correct processing is by validating all lengths against the remaining size
left before accessing referenced memory.
This makes the previously applied check obsolete, therefore I removed it.
From Tobias Stoeckmann / X.Org security advisory Oct 4, 2016
A lack of range checks in libXtst allows out of boundary accesses.
The checks have to be done in-place here, because it cannot be done
without in-depth knowledge of the read data.
If XRecordStartOfData, XRecordEndOfData, or XRecordClientDied
without a client sequence have attached data, an endless loop would
occur. The do-while-loop continues until the current index reaches
the end. But in these cases, the current index would not be
incremented, leading to an endless processing.
From Tobias Stoeckmann / X.Org security advisory Oct 4, 2016
Individual lengths inside received server data can overflow
the previously reserved memory.
It is therefore important to validate every single length
field to not overflow the previously agreed sum of all invidual
length fields.
From Tobias Stoeckmann / X.Org security advisory Oct 4, 2016
The memory for filter names is reserved right after receiving the reply.
After that, filters are iterated and each individual filter name is
stored in that reserved memory.
The individual name lengths are not checked for validity, which means
that a malicious server can reserve less memory than it will write to
during each iteration.
From Tobias Stoeckmann / X.Org security advisory Oct 4, 2016
The responses of the connected X server have to be properly checked
to avoid out of boundary accesses that could otherwise be triggered
by a malicious server.
From Tobias Stoeckmann / X.Org security advisory Oct 4, 2016
By validating length fields from server responses, out of boundary
accesses and endless loops can be mitigated.
From Tobias Stoeckmann / X.Org security advisory Oct 4, 2016
The 32 bit field "rep.length" is not checked for validity, which allows
an integer overflow on 32 bit systems.
A malicious server could send INT_MAX as length, which gets multiplied
by the size of XRectangle. In that case the client won't read the whole
data from server, getting out of sync.
From Tobias Stoeckmann / X.Org security advisory Oct 4, 2016
Check if enough bytes were received for specified image type and
geometry. Otherwise GetPixel and other functions could trigger an
out of boundary read later on.

However, that is much better than commit a W^X violation which currently
gets you killed.

mpi found where the r300 driver would not load on macppc due to an

operations and older CPUs lack the needed instructions. The hardware
supported by that driver will never be used together those older CPUs.
This might mean that even the software rasterizer doesn't work anymore on
those. But they're so slow that you probably wouldn't want to anyway.

the address of a function argument which triggers a gcc ICE on sparc64
resulting in libdrm_radeon not being built as reported by naddy.
kettenis pointed out that while other architectures probably spill the
argument onto the stack this is likely not the case on register window
architectures like SPARC and suggested passing a pointer as an argument
instead which avoids the ICE and allows the drm libraries requiring
atomics to build on sparc64 again.

This is needed by glamor egl in the xserver which is in turn needed
to get acceleration with some hardware on xf86-video-ati.
Worked on during s2k15. Glamor is not yet enabled in the xserver,
but adding this now as libepoxy recently showed up in ports.
The libepoxy port will be removed and ports will transition to
this version. The xenocara version will be enabled when we're
ready to transition.
