2058 | It is an ongoing process to be certain the hardware in a machine | |
2059 | is properly shutdown, so do not be surprised if this code does not | |
2060 | initially work for you. It may help to enable device hotplugging | |
2061 | support. As of this writing the exact hardware interface is | |

2068 | help | |
2069 | This kernel feature is useful for number crunching applications | |
2070 | that may need to compute untrusted bytecode during their | |
2071 | execution. By using pipes or other transports made available to | |
2072 | the process as file descriptors supporting the read/write | |
2073 | syscalls, it's possible to isolate those applications in | |
2074 | their own address space using seccomp. Once seccomp is | |
2075 | enabled via /proc/<pid>/seccomp, it cannot be disabled | |
2076 | and the task is only allowed to execute a few safe syscalls | |
2077 | defined by each seccomp mode. | |
