Hi Ambrarish, The fetch utility has been the case study for a lot of the compartmentalisation work on Capsicum so far. Have you considered how the download manager will handle exploitable bugs in, for example, the HTTP header parsing in libfetch? I note that your plan is to use a thread, rather than a forked process, for each request, which means that it can not run in sandboxed mode. What privilege do you imagine the daemon running with? One of the problems with fetch currently is that it is often invoked as root when downloading ports distfiles and so runs with ambient privilege of the root user.
