Welcome to the web-browser demo, showcasing the Arora web browser with a complete
|
|
networking stack running natively on a microkernel. Beware, it is a tech demo
|
|
and may be rough around the edges. But we hope you will recognise the potential
|
|
that lies in the combination of existing software with Genode's concepts.
|
|
</p>
|
|
<p>
|
|
The demo consists of three parts. The first two parts do not rely on a network
|
|
connection. All data comes from the Live-CD. So if your network connection
|
|
does not work, you are still able to test drive the first two experiments. The
|
|
third demo, however, requires an internet connection.

<h1>Why bringing Arora to Genode?</h1>
|
|
<p>
|
|
There were two reasons for porting Arora to the Genode Framework. First,
|
|
because today's web browsers, including Arora, are extremely complex, porting
|
|
such a huge software stack to a custom operating system is a great challenge.
|
|
Arora has become one of our most advanced workloads, stressing the base
|
|
system, the dynamic linker, the TCP/IP stack, and device drivers.
|
|
We chose Arora among the available web browsers because we already
|
|
had Qt running on Genode. Porting Arora seemed an evolutionary step, which
|
|
actually turned out to be the case.
|
|
</p>
|
|
<p>
|
|
But in addition to the technical challenge, we quickly recognised the potential
|
|
that lies beyond the plain porting work. Inspired by recent developments
|
|
of sandboxing techniques for browser plugins as introduced by Google Chrome, we
|
|
pursued a generalization of these ideas. What we found was, that the recursive
|
|
structure of Genode and its capability-based security are able to vastly improve
|
|
the isolation of browser plugins while, at the same time, making the plugins
|
|
more flexible.
