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

| Say Y here if you want to attach PCMCIA- or PC-cards to your Linux |

| and the newer 32 bit CardBus cards. If you want to use CardBus |
| cards, you need to say Y here and also to "CardBus support" below. |
| |
| To use your PC-cards, you will need supporting software from David |
| Hinds' pcmcia-cs package (see the file <file:Documentation/Changes> |
| for location). Please also read the PCMCIA-HOWTO, available from |
| <http://www.tldp.org/docs.html#howto>. |
