Hi.

This is mostly hypothetical, just because I want to see how knowledgeable
people would go about achieving it:

I want to sandbox Mozilla Firefox. For the sake of example, I'm running it
under my own user account. The idea is that it should be allowed to
connect to the X server, it should be allowed to write to ~/.mozilla and
/tmp.

I expect some configurations would want access to audio devices in
/dev, but for simplicity, that's ignored here.

All other filesystem access is denied.

Ready...

Go!

I forgot to add: Use of TrustedBSD extensions is, of course, allowed.

Putting an X Windows application in a sandbox is kind of silly. After
all, X has to have direct access to memory.

The X *server* needs direct access to memory. X clients (like Firefox or
just about any other application using X) does not need direct access to
memory. They don't even need to run on the same machine as the X server.




A virtual machine
approach, with a whole virtual set of memory, might make more sense.
I use that (via qemu), although not for exactly the same reasons.
