* Fix overflow checks in _XkbReadKeySyms when key_sym_map is already createdAlan Coopersmith2016-10-191-5/+4
| | | | | | | | | | | | | | | | | | | | We were checking to make sure that the largest keysym value was within the range of the allocated buffer, but checking against different limits in the not-yet-allocated vs. the already-allocated branches. The check should be the same in both, and reflect the size used for the allocation, which is based on the maximum key code value, so we move it to be a common check, before we branch, instead of duplicating in each branch. map->key_sym_map is an array of XkbSymMapRec structs, [0..max_key_code] map->syms is the array for which num_syms is recorded, hence is not the right value to check for ensuring our key_sym_map accesses are in range.

* Align files with upstream libX11-1.6.0Ulrich Sibiller2016-10-191-1/+0
| | | | | | | | | | | | 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.
* xkb: fix off-by-one in _XkbReadGetNamesReply and _XkbReadVirtualModMapJulien Cristau2016-10-191-1/+1
| | | | | | | | | | | | The size of the arrays is max_key_code + 1. This makes these functions consistent with the other checks added for CVE-2013-1997. Also check the XkbGetNames reply when names->keys was just allocated.

Quote Alan Coopersmith: "The consumer was in past versions of the headers now located in proto/x11proto - for instance, in X11R6.0's xc/include/Xproto.h, all the event definitions were only available if NEED_EVENTS were defined, and all the reply definitions required NEED_REPLIES. Looks like Xproto.h dropped them by X11R6.3, which didn't have the #ifdef's anymore, so these are truly ancient now."

* Clear header file namespace separation (<X11/...> vs. <nx-X11/...>).Mike Gabriel2015-12-281-1/+1
| | | | | | | | | | | | | | | | | | | | 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.
