  In NetBSD and OpenBSD, user-land process and process-context isolation is limited to credential cross-checks, file-system chroot and explicit systrace/kauth applications. I'll demonstrate a working mechanism of isolated process trees in branched OpenBSD-4.4 and NetBSD-5.0-beta kernels where an isolated process is started by a system call similar to fork; following that, the child process and its descendants execute in a context isolated from the caller. This system is the continued work of "mult" -- first prototyped in a branched NetBSD-3.1 kernel and isolating all system resources -- pared down to a lightweight, auditable patch of process-only separation for both OpenBSD and NetBSD. I specifically address solutions to performance issues and mechanism design with an eye toward more resources being isolated in the future.
