* Add REGION_ macros for source compatibility with existing drivers.Mike Gabriel2016-05-021-0/+39
| | | | | | | | | | | | This makes the region code changes source compatible with existing code, although none of them are used within the server source itself. In NX, this patch is not really necessary, but it has been backported with the previous patches for the sake of backporting the complete mi/miregion.c -> dix/region.c change in X.Org. v1: Keith Packard <keithp@keithp.com> v2: Mike Gabriel <mike.gabriel@das-netzwerkteam.de> (backported to nx-libs)
* Change region implementation names to eliminate the 'mi' prefixMike Gabriel2016-05-021-30/+30
| | | | | | | | | | This prepares the file to be moved from mi to dix. This patch was done mechanically with the included scripts 'fix-miregion' run over the entire X server and 'fix-miregion-private' run over include/regionstr.h and mi/miregion.c. v1: Keith Packard <keithp@keithp.com> v2: Mike Gabriel <mike.gabriel@das-netzwerkteam.de> (backported to nx-libs)

* Change region implementation from macros to inline functions.Mike Gabriel2016-05-023-224/+183
| | | | | | | | | 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>
* Rename region macros to eliminate screen argumentMike Gabriel2016-05-021-57/+57
| | | | | | | | | | | | | | | | | | | | | This is a huge mechanical patch and a few small fixups required to finish the job. They were reviewed separately, but because the server does not build without both pieces, I've merged them together at this time. The mechanical changes were performed by running the included 'fix-region' script over the whole nx-X11/programs/Xserver tree: $ cd nx-X11/programs/Xserver && ( git ls-files | grep -v '^fix-' | xargs ./fix-region; ) And then, the white space errors in the resulting patch were fixed using the provided fix-patch-whitespace script. $ sh ./fix-patch-whitespace Thanks to Jamey Sharp for the mighty fine sed-generating sed script. v1: Keith Packard <keithp@keithp.com> (X.Org xserver commit: 2dc138922b7588515d5f2447e4b9dcdc0bef15e0) v2: Mike Gabriel <mike.gabriel@das-netzwerkteam.de> (apply fix-region script to nx-libs)

* Clear header file namespace separation (<X11/...> vs. <nx-X11/...>).Mike Gabriel2015-12-2815-24/+24
| | | | | | | | | | | | | | | | | | | | 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 Packard2015-12-2823-120/+131
| | | | | | | | | | 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>
* Xi: unvalidated lengths in Xinput extension [CVE-2014-8095]Alan Coopersmith2015-02-141-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. v2: backport to nx-libs 3.6.x (Mike DePaulo) Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com> Reviewed-by: Peter Hutterer <peter.hutterer@who-t.net> Conflicts: Xi/chgdctl.c Xi/chgfctl.c Xi/xiallowev.c Xi/xichangecursor.c Xi/xichangehierarchy.c Xi/xigetclientpointer.c Xi/xigrabdev.c Xi/xipassivegrab.c Xi/xiproperty.c Xi/xiquerydevice.c Xi/xiquerypointer.c Xi/xiselectev.c Xi/xisetclientpointer.c Xi/xisetdevfocus.c Xi/xiwarppointer.c [RHEL5: Xi/xi* files are XI2 ]
