* Align files with upstream libX11-1.6.0Ulrich Sibiller2016-10-191-6/+6
| | | | | | | | | | | | This commit looks a bit crazy at first glance. It (re-)introduces lots of whitespaces and bad formatting. Explanation: Backporting upstream changes lead to commits being applied out of order. This meant a lot of manual intervention which in turn lead to slight differences between upstream and NX. With this commit these slight differences are minimized which will be of great help when adding further upstream patches.
* integer overflow in ReadInFile() in Xrm.c [CVE-2013-1981 7/13]Alan Coopersmith2016-10-191-2/+4
| | | | | | | | | | | | | | | | | | Called from XrmGetFileDatabase() which gets called from InitDefaults() which gets the filename from getenv ("XENVIRONMENT") If file is exactly 0xffffffff bytes long (or longer and truncates to 0xffffffff, on implementations where off_t is larger than an int), then size may be set to a value which overflows causing less memory to be allocated than is written to by the following read() call. size is left limited to an int, because if your Xresources file is larger than 2gb, you're very definitely doing it wrong.

* Unbounded recursion in GetDatabase() when parsing include files ↵Alan Coopersmith2016-10-121-9/+15
| | | | | | | | | | | | | | | | | | | [CVE-2013-2004 1/2] GetIncludeFile() can call GetDatabase() which can call GetIncludeFile() which can call GetDatabase() which can call GetIncludeFile() .... eventually causing recursive stack overflow and crash. Easily reproduced with a resource file that #includes itself. Limit is set to a include depth of 100 files, which should be enough for all known use cases, but could be adjusted later if necessary.

* Clear header file namespace separation (<X11/...> vs. <nx-X11/...>).Mike Gabriel2015-12-281-2/+2
| | | | | | | | | | | | | | | | | | | | 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.
