| 555 | This kernel feature is useful for number crunching applications |
| 556 | that may need to compute untrusted bytecode during their |
| 557 | execution. By using pipes or other transports made available to |
| 558 | the process as file descriptors supporting the read/write |
| 559 | syscalls, it's possible to isolate those applications in |
| 560 | their own address space using seccomp. Once seccomp is |
| 561 | enabled via /proc/<pid>/seccomp, it cannot be disabled |
| 562 | and the task is only allowed to execute a few safe syscalls |
