602 kexec is a system call that implements the ability to shutdown your
603 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400604 but it is independent of the system firmware. And like a reboot

Matt LaPlante1f1332f2006-06-29 01:32:47 -0400607 The name comes from the similarity to the exec system call.

651 This kernel feature is useful for number crunching applications
652 that may need to compute untrusted bytecode during their
653 execution. By using pipes or other transports made available to
654 the process as file descriptors supporting the read/write

656 their own address space using seccomp. Once seccomp is
657 enabled via prctl, it cannot be disabled and the task is only
658 allowed to execute a few safe syscalls defined by each seccomp
659 mode.
