NAME

6       ipsec__stackmanager - internal script to bring up kernel components for
7       Libreswan
8

SYNOPSIS

10       ipsec _stackmanager start [--xfrm]
11
12       ipsec _stackmanager stop
13

DESCRIPTION

15       ipsec _stackmanager is called from within the init sub-system (systemd,
16       upstart, sysv initscripts) to bring up the Libreswan kernel component
17       as configured via the protostack= option in the ipsec.conf
18       configuration file.
19
20       This involves loading and optionally unloading of the required kernel
21       modules. Because the Linux kernel cannot autodetect most crypto related
22       drivers on-demand, _stackmanager handles loading the modules for the
23       specific IPsec stack.
24
25       When the --xfrm option is given to the start command, the XFRM stack is
26       loaded regardless of the existence or contents of the ipsec.conf file.
27       This is used for docker tests where the host system, which might not
28       have libreswan installed, needs to run _stackmanager from the source
29       tree to load the modules on the host so the modules are available
30       inside the containers.

HISTORY

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