After a cvs import timestamps change which triggers rules that attempt
to call python to regenerate files. When python is not found this
generates empty files that override those from the distfile, breaking
the build.
When building inside xenocara python is never found as the pkg paths
are not searched.
The existing code walks all of /dev looking for different types of drm
nodes. We just have primary nodes and can directly map the minor number
to a path.

Always return DRM_BUS_PCI for now. No non-pci drm drivers are in the
kernel and this is unlikely to change anytime soon as the existing ones
aren't permissively licensed.

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:
override rw-r--r-- root/wheel for ks_tables.h?
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.

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.

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.

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.
