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

126 | the process as file descriptors supporting the read/write | |
127 | syscalls, it's possible to isolate those applications in | |
128 | their own address space using seccomp. Once seccomp is | |
129 | enabled via /proc/<pid>/seccomp, it cannot be disabled | |
130 | and the task is only allowed to execute a few safe syscalls | |
