The failing struct comes from the python test written by Michal Srb <msrb@suse.com>. v2: Use a drawable (root window) and gc, so that PolyLines hopefully actually tries processing things. However, the request seems to process successfully so the poll() just stalls out. However, this does let us distinguish between detecting the bigrequests error and not, at least. v3: Clean up the description of what we expect the poll() call to do. v4: Use XI2 instead of PolyLine to trigger a predictable error. We know the server replies with BadValue for a zero num_masks argument. So if we send a bigreq with a num_masks 0 and a length 0, we can just check whether we get killed (good) or a BadValue (bad). It doesn't test for specific memory overflows or crashes, but based on the assumption that we shouldn't look at *any* BigReq of size 0, this seems to be sufficient.

X Server The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into. Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders. For a comprehensive overview of X Server and X Window System, consult the following article: https://en.wikipedia.org/wiki/X_server All questions regarding this software should be directed at the Xorg mailing list: https://lists.freedesktop.org/mailman/listinfo/xorg Please submit bug reports to the Xorg bugzilla: https://bugs.freedesktop.org/enter_bug.cgi?product=xorg The master development code repository can be found at: git://anongit.freedesktop.org/git/xorg/xserver https://cgit.freedesktop.org/xorg/xserver For patch submission instructions, see: https://www.x.org/wiki/Development/Documentation/SubmittingPatches For more information on the git code manager, see: https://wiki.x.org/wiki/GitPage As with other projects hosted on freedesktop.org, X.Org follows its Code of Conduct, based on the Contributor Covenant.
