| 331 | ---help--- |
| 332 | This kernel feature is useful for number crunching applications |
| 333 | that may need to compute untrusted bytecode during their |
| 334 | execution. By using pipes or other transports made available to |
| 335 | the process as file descriptors supporting the read/write |
| 336 | syscalls, it's possible to isolate those applications in |
| 337 | their own address space using seccomp. Once seccomp is |
| 338 | enabled via prctl(PR_SET_SECCOMP), it cannot be disabled |
| 339 | and the task is only allowed to execute a few safe syscalls |
| 340 | defined by each seccomp mode. |
| 341 | |
| 342 | If unsure, say Y. Only embedded should say N here. |
