NAME
       ipsec__stackmanager - internal script to bring up kernel components for Libreswan


SYNOPSIS
       ipsec _stackmanager start [--netkey]

       ipsec _stackmanager stop


DESCRIPTION
       ipsec _stackmanager is called from within the init sub-system (systemd, upstart, sysv initscripts) to
       bring up the Libreswan kernel component as configured via the protostack= option in the ipsec.conf
       configuration file.

       This involves loading and optionally unloading of the required kernel modules. Because the Linux kernel
       cannot autodetect most crypto related drivers on-demand, _stackmanager handles loading the hardware
       random number (RNG) device drivers, OpenBSD/FreeBSD Cryptographic Framework (OCF) drivers, CryptoAPI
       drivers, and the modules for the specific stack (Linux NETKEY/XFM or KLIPS/MAST). Probing for OCF
       supported hardware is not supported - those modules must be loaded by the system before the start of the
       Libreswan sub system.

       When the --netkey option is given to the start command, the netkey stack is loaded regardless of the
       existence or contents of the ipsec.conf file. This is used for docker tests where the host system, which
       might not have libreswan installed, needs to run _stackmanager from the source tree to load the modules
       on the host so the modules are available inside the containers.

HISTORY
       This script was introduced in Libreswan. On the older Openswan systems, this functionality was split over
       various script files such as ipsec _startnetkey, ipsec _startklips, ipsec _realsetup and ipsec setup. Man
