Sysjail
sysjail is a defunct user-land virtualiser for systems supporting the systrace library - as of version 1.0 limited to OpenBSD, NetBSD and MirOS. Its original design was inspired by FreeBSD jail, a similar utility (although part of the kernel) for FreeBSD. sysjail was developed and released in 2006 by Kristaps Dzonsons (aka Johnson), a research assistant in Game theory at the Stockholm School of Economics, and Maikls Deksters.
sysjail was re-written from scratch in 2007 to support emulated processes in jails, limited (initially) to Linux emulation.
The project was officially discontinued on 3 March 2009 due to flaws inherent to syscall wrapper-based security architectures. The restrictions of sysjail could be evaded by exploiting race conditions between the wrapper's security checks and kernel's execution of the syscalls.
