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 OpenBSD/FreeBSD
23       Cryptographic Framework (OCF) drivers, CryptoAPI drivers, and the
24       modules for the specific IPsec stack (Linux XFRM or KLIPS). Probing for
25       OCF supported hardware is not supported - those modules must be loaded
26       by the system before the start of the Libreswan sub system.
27
28       When the --xfrm option is given to the start command, the XFRM stack is
29       loaded regardless of the existence or contents of the ipsec.conf file.
30       This is used for docker tests where the host system, which might not
31       have libreswan installed, needs to run _stackmanager from the source
32       tree to load the modules on the host so the modules are available
33       inside the containers.

HISTORY

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