  1562. This kernel feature is useful for number crunching applications
  1563. that may need to compute untrusted bytecode during their
  1564. execution. By using pipes or other transports made available to
  1565. the process as file descriptors supporting the read/write
  1566. syscalls, it's possible to isolate those applications in
  1567. their own address space using seccomp. Once seccomp is
  1568. enabled via /proc/<pid>/seccomp, it cannot be disabled
  1569. and the task is only allowed to execute a few safe syscalls
  1570. defined by each seccomp mode.
