604 kexec is a system call that implements the ability to shutdown your
605 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400606 but it is independent of the system firmware. And like a reboot

653 This kernel feature is useful for number crunching applications
654 that may need to compute untrusted bytecode during their
655 execution. By using pipes or other transports made available to
656 the process as file descriptors supporting the read/write
657 syscalls, it's possible to isolate those applications in
658 their own address space using seccomp. Once seccomp is
659 enabled via prctl, it cannot be disabled and the task is only
660 allowed to execute a few safe syscalls defined by each seccomp
661 mode.
