113 help
114 This kernel feature is useful for number crunching applications
115 that may need to compute untrusted bytecode during their
116 execution. By using pipes or other transports made available to
117 the process as file descriptors supporting the read/write
118 syscalls, it's possible to isolate those applications in
119 their own address space using seccomp. Once seccomp is
120 enabled via /proc/<pid>/seccomp, it cannot be disabled
121 and the task is only allowed to execute a few safe syscalls
122 defined by each seccomp mode.
123
124 If unsure, say Y. Only embedded should say N here.
