Subject: [PATCH] vmware-vga: CVE-2014-3689: turn off hw accel
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Quick & easy stopgap for CVE-2014-3689:  We just compile out the
hardware acceleration functions which lack sanity checks.  Thankfully
we have capability bits for them (SVGA_CAP_RECT_COPY and
SVGA_CAP_RECT_FILL), so guests should deal just fine, in theory.

Subsequent patches will add the missing checks and re-enable the
hardware acceleration emulation.
