120 | This kernel feature is useful for number crunching applications | |

122 | execution. By using pipes or other transports made available to | |
123 | the process as file descriptors supporting the read/write | |
124 | syscalls, it's possible to isolate those applications in | |
125 | their own address space using seccomp. Once seccomp is | |
126 | enabled via /proc/<pid>/seccomp, it cannot be disabled | |
127 | and the task is only allowed to execute a few safe syscalls | |
