If the attacker gets full administrator-level access on your machine, there are a gazillion ways the attacker can prevent other admins from logging on. This patch can't prevent that. It sounds like this patch is trying to solve a fundamentally unsolveable problem. A useful slogan: "Don't forbid what you cannot prevent." -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
