ptrace() is ok, but it also has lots of disadvantages: performance, expressiveness, security, assurance. I've posted before on this mailing list, at length, about them. In short, ptrace() is not an ideal solution, and a secure chroot() or other way to construct a jail/sandbox would be better. (LSM will be much better.) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
