| * dbe: Call to DDX SwapBuffers requires address of int, not unsigned int ↵Keith Packard2016-10-201-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [CVE-2014-8097 pt. 2] When the local types used to walk the DBE request were changed, this changed the type of the parameter passed to the DDX SwapBuffers API, but there wasn't a matching change in the API definition. At this point, with the API frozen, I just stuck a new variable in with the correct type. Because we've already bounds-checked nStuff to be smaller than UINT32_MAX / sizeof(DbeSwapInfoRec), we know it will fit in a signed int without overflow.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The basic rule "put parantheses around macro parameters" should be observed where possible. Otherwise code like ConnectionNumber(foo = bar); fails to compile. (It obviously passes if ConnectionNumber is a C function.) There are several other macros amended for the same reason. This bug appeared while building http://ioccc.org/1993/cmills.c, so historically it was not present.

| * XKB: fix XkbGetKeyboardByName with Xming serverOlivier Fourdan2016-10-191-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | XkbGetKeyboardByName relies on flags to read the data from the server. If the X server sends us the wrong flags or if a subreply is smaller than it should be, XkbGetKeyboardByName will not read all the available data and leave data in the buffer, which will cause the next _XReply() to fail with: [xcb] Extra reply data still left in queue [xcb] This is most likely caused by a broken X extension library [xcb] Aborting, sorry about that. xcb_io.c:576: _XReply: Assertion `!xcb_xlib_extra_reply_data_left' failed. Aborted Check if there is some extra data left at the end of XkbGetKeyboardByName() and discard that data if any is found.
