1721 | help | |
1722 | kexec is a system call that implements the ability to shutdown your | |
1723 | current kernel, and to start another kernel. It is like a reboot | |
3dde6ad8 | 1724 | but it is independent of the system firmware. And like a reboot |
ea6e942b AN |
1725 | you can start any kernel with it, not just Linux. |
1726 | ||
1727 | The name comes from the similiarity to the exec system call. | |
1728 | ||
1729 | It is an ongoing process to be certain the hardware in a machine | |
1730 | is properly shutdown, so do not be surprised if this code does not | |
1731 | initially work for you. It may help to enable device hotplugging | |
1732 | support. As of this writing the exact hardware interface is | |

1739 | help | |
1740 | This kernel feature is useful for number crunching applications | |
1741 | that may need to compute untrusted bytecode during their | |
1742 | execution. By using pipes or other transports made available to | |
1743 | the process as file descriptors supporting the read/write | |
1744 | syscalls, it's possible to isolate those applications in | |
1745 | their own address space using seccomp. Once seccomp is | |
1746 | enabled via /proc/<pid>/seccomp, it cannot be disabled | |
1747 | and the task is only allowed to execute a few safe syscalls | |
1748 | defined by each seccomp mode. | |
