* Fix wrong Xfree in XListFonts failure pathJulien Cristau2017-03-261-2/+4
| | | | | | | | | | | | 'ch' gets moved inside the allocated buffer as we're looping through fonts, so keep a reference to the start of the buffer so we can pass that to Xfree in the failure case.

* Remove redundant null checks before freewalter harms2016-10-191-2/+2
| | | | | | | | | | | This patch removes some redundant null checks before free. It should not change the code otherwise. Be aware that this is only the first series.

* Tighten out-of-range comparisons.Thomas Klausner2016-10-191-1/+1
| | | | | | | | | | | | | [For all of these, LONG_MAX was the correct value to prevent overflows for the recent CVEs. Lowering to INT_MAX catches buggy replies from the server that 32-bit clients would reject but 64-bit would accept, so we catch bugs sooner, and really, no sane & working server should ever report more than 2gb of extension names, font path entries, key modifier maps, etc. -alan- ] Reviewed-by: Alan Coopersmith <alan.coopersmith@oracle.com> Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com> Backported-to-NX-by: Ulrich Sibiller <uli42@gmx.de>

* remove unreferenced NEED_EVENTS/NEED_REPLIESUlrich Sibiller2016-07-051-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove defines of NEED_EVENTS and NEED_REPLIES because they are never used anywhere. Basically these three commits, but as they are newer and to not match the code structure the patches have not been applied but replaced by sed + manual intervention: From cb95642dc8edebb2935dd471f8b339cb98aa8481 Mon Sep 17 00:00:00 2001 From: Peter Hutterer <peter.hutterer@redhat.com> Date: Fri, 28 Nov 2008 22:28:32 +1000 Subject: Remove #define NEED_EVENTS and NEED_REPLIES A grep on xorg/* revealed there's no consumer of this define. 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."
