* Font.c: replace memcpy by sprintf preventing possible buffer overflowsUlrich Sibiller2018-01-071-9/+3
| | | | | | I am not sure about the maximum font name length in X but just in case use snprintf instead of memcpy to be sure nothing dangerous can happen here.

| | | | | | | This is a partial copy from XlibInt.c's _XPrintDefaultError, which had some minor changes since being copied. Update to reflect these changes. Also comment some more lines as their result was unused an cluttered the output.

* nx-X11: reintroduce creation of libX11 compat symlinks.Mihai Moldovan2017-12-301-0/+2
| | | | | We need this to be able to execute the resulting nxagent binary from within the build directory.

* nxagent: implement RPATH/RUNPATH override for libX11.Mihai Moldovan2017-12-301-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | As discussed in ArcticaProject/nx-libs#610, we need a way to load libNX_X11 as a fake version of libX11 into nxagent's address space. For doing so, we have to link against libX11 at build-time and specify a(n) RPATH/RUNPATH to our libX11 -> libNX_X11 compat symlinks. This commit is essentially doing a cross between options 3 and 4 discussed in the provided GH issue. We link libX11 early (before specifying -Lcompat_symlinks_dir), so that the linker finds the "real" libX11 version with the libX11 SONAME. This leads to our binary depending upon both libX11 and libNX_X11 SONAMEs. We already always added RPATH/RUNPATH, but these values are not passed down to dependent libraries. What happens at run-time is that the loader searches for a libX11 SONAME, takes RPATH/RUNPATH into account and loads our libNX_X11 library instead via the compat symlinks. This satisfies the libX11 SONAME and dependent libraries will *not* load the system libX11 version again. Debian's dpkg-shlibdeps isn't quite happy about this mismatching SONAME situation, so instruct to look the other way while we're minding our business. Fixes: ArcticaProject/nx-libs#610

* Xserver/hw/nxagent/Clipboard.c: Fix free calls (free back to XFree).Mike Gabriel2017-12-151-3/+3
| | | | | | | | | | | They have been flawed ever since nxagent came up, as they were Xfree (non-capital f) always, but should have been XFree (capital F, defined in Xlibint.h and part of libNX_X11). . Probably this all should be free() all over the code (bearing in mind, that XFree() returns int, not void. But still... Fixes ArcticaProject/nx-libs#553.

* Xserver/GL/glx/glxcmds.c: Cast small-int values through intptr_t when passed ↵Mike Gabriel2017-12-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | as pointers Picked from this X.org commit: commit b0dd6be2c8703f7062d45ac9fd646550c7d54e3b Author: Jamey Sharp <jamey@minilop.net> Date: Thu Oct 8 13:38:44 2009 +1100 Cast small-int values through intptr_t when passed as pointers On 64-bit systems, int and pointers don't have the same size, so GCC gives warnings about casts between int and pointer types. However, in the cases covered by this patch, it's always a value that fits in int being stored temporarily as a pointer and then converted back later, which is safe. Casting through the pointer-sized integer type intptr_t convinces the compiler that this is OK.
