607 kexec is a system call that implements the ability to shutdown your
608 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400609 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800610 you can start any kernel with it, not just Linux.
611
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400612 The name comes from the similarity to the exec system call.

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