623 kexec is a system call that implements the ability to shutdown your
624 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400625 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800626 you can start any kernel with it, not just Linux.
627
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400628 The name comes from the similarity to the exec system call.
Paul Mundtcad82442006-01-16 22:14:19 -0800629
630 It is an ongoing process to be certain the hardware in a machine
631 is properly shutdown, so do not be surprised if this code does not
632 initially work for you. It may help to enable device hotplugging
633 support. As of this writing the exact hardware interface is
634 strongly in flux, so no good recommendation can be made.

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