current implementation, jail neither virtualizes the Sys V IPC namespace, nor provides inter-jail protections on IPC objects. o Support for System V IPC can be enabled by setting jail.sysvipc_allowed=1 using sysctl. o This is not the "real fix" which involves virtualizing the System V IPC namespace, but prevents processes within jail from influencing those outside of jail when not approved by the administrator.
