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.
|
||||||
|
|
||||||
|
If unsure, say Y. Only embedded should say N here.
