The IPsec stack integrated in the Linux kernel since 2.6 (NETKEY) was originally based on the KAME stack (at least in regards to the API). The source code is part of the kernel repository, where the main components are found in the net/xfrm folder, including the implementation of the Netlink/XFRM configuration interface. The alternative and standardized (but somewhat extended) PF_KEYv2 ...

Using IPSEC is an example of the need to add additional support to our kernel to be used as explained in a previous article on the Linux Kernel. You can implement IPSEC on Linux with strongSwan, on Debian and Ubuntu systems you can type:

As of Linux 2.5.47, there is a native IPSEC implementation in the kernel. It was written by Alexey Kuznetsov and Dave Miller, inspired by the work of the USAGI IPv6 group. With its merge, James Morris' CrypoAPI also became part of the kernel - it does the actual crypting. This HOWTO will only document the 2.5+ version of IPSEC.

Created attachment 879721 Patch to enable kernel-libipsec plugin in RPM spec. Description of problem: Since strongSwan 5.1.0, it provides a plugin called kernel-libipsec which provides an IPsec backend that works entirely in userland, using TUN devices and its own IPsec implementation libipsec to emulate the IPSec. Fedora has compiled kernel interface kernel-netlink, it installs IPsec SAs in ...

Oct 19, 2014 · There are dozens of RFCs and articles explain the IPSec protocols in depth. Though the major part of IPSec is embedded inside the Operating systems like Linux, its implementation details are rarely documented. This article is an attempt to peek into the details of IPSec framework of Linux kernel TCP/IP stack. Basics at a G lance

Linux Kernel 2.6 using KAME-tools. This chapter explains the usage of the native IPsec stack of the Linux Kernel ≥2.5.47 and 2.6.*. The installation and the configuration of this IPsec stack differs greatly from FreeS/WAN and is similar to the *BSD variants like FreeBSD, NetBSD and OpenBSD.

And for those users who needed a newer Linux than 2.4.18 for their hardware, and had been using 2.4.20, the situation was problematic. The newer Linux source packages could not be unpatched to remove the IPsec support without failed hunks. Neither could the FreeS/WAN source be patched to understand the new API without similar problems.

The Linux kernel NETKEY code is a rewrite from scratch of the KAME IPsec code. The KAME Project was a group effort of six companies in Japan to provide a free IPv6 and IPsec (for both IPv4 and IPv6) protocol stack implementation for variants of the BSD UNIX computer operating system. KLIPS is not a part of the Linux kernel.
