Emont: Video decoding in a sandbox Guillaume Emont describes
his work using the Chromium sandbox mechanism to make video decoding in GStreamer more secure. " The way setuid-sandbox works is rather
straightforward: there is a sandboxme command that needs to be installed
setuid root. You run sandboxme my_command and then from inside my_command,
you first set up the file descriptors that you will need (being careful not
to put there anything that could allow to escape the sandbox, more on that
later), and then you call the provided chrootme() function, which will tell
the sandboxme process to restrict the privileges that my_command has
(e.g. it can still read and write on the fds that it has open, but it
cannot open new ones)." | | 4:57p |

[$] LCA: The X-men speak Linux.conf.au 2013 in Canberra
provided an interesting window into the world of
display server development with a pair of talks about the X Window
System and one about
its planned successor Wayland (a talk which will be the subject of its own
article shortly). First, Keith Packard discussed coming
improvements to compositing and rendering. He was followed by David
Airlie, who talked about recent changes and upcoming new features for
the Resize, Rotate and Reflect Extension (RandR), particularly to cope
with multiple-GPU laptops. Each talk was each entertaining enough in
its own right, but they worked even better together as the speakers
interjected their own comments into one another's Q&A period (or, from
time to time, during the talks themselves). | | 7:25p |
