Daniel Bernstein has observed that security-conscious unprivileged userland processes may benefit from the ability to irrevocably remove their ability to create, bind, connect to, or send messages to non-AF_UNIX sockets.
This patch defines a 'long sys_disablenetwork(void)' syscall and implements it in an LSM in order to avoid modifying the definition of 'struct task_struct'.
