* include: add version_compare helper functionMike Gabriel2016-06-211-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backported from X.org: commit 0df871cf34ee5f1a85586206027de9b02fb364ec Author: Robert Ancell <robert.ancell@canonical.com> Date: Thu May 22 10:43:52 2014 +1200 Fix overflow checking extension versions The easiest way to check for the version of an extension is to send the maximum possible version numbers in the QueryVersion request. The X server overflows on these as it assumes you will send a reasonable version number.

| | | | | | | | | This makes all of the previous macros into inline functions and also turns all of the direct calls to pixman region code into inline functions as well. v1: Keith Packard <keithp@keithp.com> v2: Mike Gabriel <mike.gabriel@das-netzwerkteam.de>

* Clear header file namespace separation (<X11/...> vs. <nx-X11/...>).Mike Gabriel2015-12-281-6/+6
| | | | | | | | | | | | | | | | | | | | In the process of building nxagent against more and more system-wide installed X.org libraries, we come to the limit of including structs from this (bundled nx-X11) and that (system-wide X.Org) library. This commit introduces a clear namespace separation of headers provided by nx-X11 and headers provided by X.Org. This approach is only temporary as we want to drop all nx-X11 bundled libraries from nx-libs. However, for a while we need to make this separation clear and also ship some reduced fake X.Org headers that avoid pulling in libX* and libNX_X* symbols at the same time. This patch has been tested on Debian jessie and unstable and requires no overall testing on various distros and distro versions, as we finally will drop all libNX_X* libraries and build against X.org's client libs. For now, this hack eases our development / cleanup process.
* Replace 'pointer' type with 'void *'Keith Packard2015-12-281-0/+5
| | | | | | | | | | This lets us stop using the 'pointer' typedef in Xdefs.h as 'pointer' is used throughout the X server for other things, and having duplicate names generates compiler warnings.

* include: introduce byte counting functions.Peter Hutterer2015-02-171-0/+30
| | | | | | | | | | | | | | | | | | | | This patch adds the following three functions: bits_to_bytes(bits) - the number of bytes needed to hold 'bits' bytes_to_int32(bytes) - the number of 4-byte units to hold 'bytes' pad_to_int32(bytes) - the closest multiple of 4 equal to or larger than 'bytes'. All three operations are common in protocol processing and currently the server has ((foo + 7)/8 + 3)/4 operations all over the place. A common set of functions reduce the error rate of these (albeit simple) calculations and improve readability of the code. The functions do not check for overflow. v2: backport to nx-libs 3.6.x as a prereq for the CVE-2015-0255 fix (Mike DePaulo) Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
