| 553 | kexec is a system call that implements the ability to shutdown your |
| 554 | current kernel, and to start another kernel. It is like a reboot |
Matt LaPlante | 1f1332f | 2006-06-29 01:32:47 -0400 | [diff] [blame] | 555 | but it is independent of the system firmware. And like a reboot |

| 591 | This kernel feature is useful for number crunching applications |
| 592 | that may need to compute untrusted bytecode during their |
| 593 | execution. By using pipes or other transports made available to |
| 594 | the process as file descriptors supporting the read/write |
| 595 | syscalls, it's possible to isolate those applications in |
| 596 | their own address space using seccomp. Once seccomp is |

| 598 | allowed to execute a few safe syscalls defined by each seccomp |
