ipsec-_stackmanager8
Internal script to bring up kernel components for libreswan
Usage
ipsec _stackmanager
{start | stop}
Overview
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.
