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

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