From 9ca8dbcc65cfc63d6f5ef3312a33184e1d726e00 Mon Sep 17 00:00:00 2001 From: Yunhong Jiang Date: Tue, 4 Aug 2015 12:17:53 -0700 Subject: Add the rt linux 4.1.3-rt3 as base Import the rt linux 4.1.3-rt3 as OPNFV kvm base. It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and the base is: commit 0917f823c59692d751951bf5ea699a2d1e2f26a2 Author: Sebastian Andrzej Siewior Date: Sat Jul 25 12:13:34 2015 +0200 Prepare v4.1.3-rt3 Signed-off-by: Sebastian Andrzej Siewior We lose all the git history this way and it's not good. We should apply another opnfv project repo in future.

It +is composed of three main components, the protocol engines, the communication +layer, and the kernel security module API. + + * Protocol Engines + +The protocol engines are responsible for both applying and retrieving the +network packet's security attributes. If any translation between the network +security attributes and those on the host are required then the protocol +engine will handle those tasks as well. Other kernel subsystems should +refrain from calling the protocol engines directly, instead they should use +the NetLabel kernel security module API described below. + +Detailed information about each NetLabel protocol engine can be found in this +directory, consult '00-INDEX' for filenames. + + * Communication Layer + +The communication layer exists to allow NetLabel configuration and monitoring +from user space. The NetLabel communication layer uses a message based +protocol built on top of the Generic NETLINK transport mechanism. The exact +formatting of these NetLabel messages as well as the Generic NETLINK family +names can be found in the 'net/netlabel/' directory as comments in the +header files as well as in 'include/net/netlabel.h'. + + * Security Module API + +The purpose of the NetLabel security module API is to provide a protocol +independent interface to the underlying NetLabel protocol engines. In addition +to protocol independence, the security module API is designed to be completely +LSM independent which should allow multiple LSMs to leverage the same code +base. + +Detailed information about the NetLabel security module API can be found in the +'include/net/netlabel.h' header file as well as the 'lsm_interface.txt' file +found in this directory. -- cgit 1.2.3-korg
