* Use _cairo_malloc instead of mallocAdrian Johnson2018-05-071-3/+3
| | | | | | | | | | _cairo_malloc(0) always returns NULL, but has not been used consistently. This patch replaces many calls to malloc() with _cairo_malloc(). Fixes: fdo# 101547 CVE: CVE-2017-9814 Heap buffer overflow at cairo-truetype-subset.c:1299 Reviewed-by: Bryce Harrington <bryce@osg.samsung.com>
* xlib/shm: Discard damage upon shm finishChris Wilson2013-01-081-0/+7
| | | | | | | | | Both to make sure we do not leak the memory, but to also prevent _cairo_xlib_surface_put_shm() from operating upon the finished shm surface after the display is closed.

This is initially based around the requirements for handling internal fallbacks to the image compositor and reducing the number of pixels required to be transferred. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
