| 2000 | This kernel feature is useful for number crunching applications |
| 2001 | that may need to compute untrusted bytecode during their |
| 2002 | execution. By using pipes or other transports made available to |
| 2003 | the process as file descriptors supporting the read/write |
| 2004 | syscalls, it's possible to isolate those applications in |
| 2005 | their own address space using seccomp. Once seccomp is |
| 2006 | enabled via /proc/<pid>/seccomp, it cannot be disabled |
| 2007 | and the task is only allowed to execute a few safe syscalls |
| 2008 | defined by each seccomp mode. |
