NAME

       ipsec__stackmanager - internal script to bring up kernel components for Libreswan

SYNOPSIS

       ipsec _stackmanager start [--xfrm]

       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 modules for the specific IPsec stack.

       When the --xfrm option is given to the start command, the XFRM 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 page written for the Libreswan project
