+ bool "Enable seccomp to safely compute untrusted bytecode"
+ depends on PROC_FS
+ default y
+ 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.
+ If unsure, say Y. Only embedded should say N here.
