By using pipes or other transports made available to 1795 the process as file descriptors supporting the read/write 1796 syscalls, it's possible to isolate those applications in 1797 their own address space using seccomp. Once seccomp is 1798 enabled via /proc/<pid>/seccomp, it cannot be disabled 1799 and the task is only allowed to execute a few safe syscalls 1800 defined by each seccomp mode. 1801 1802 If unsure, say Y.
