From 00959ade36acadc00e757f87060bf6e4501d545f Mon Sep 17 00:00:00 2001 From: Dmitry Kozlov Date: Sat, 21 Aug 2010 23:05:39 -0700 Subject: PPTP: PPP over IPv4 (Point-to-Point Tunneling Protocol) PPP: introduce "pptp" module which implements point-to-point tunneling protocol using pppox framework NET: introduce the "gre" module for demultiplexing GRE packets on version criteria (required to pptp and ip_gre may coexists) NET: ip_gre: update to use the "gre" module This patch introduces then pptp support to the linux kernel which dramatically speeds up pptp vpn connections and decreases cpu usage in comparison of existing user-space implementation (poptop/pptpclient). There is accel-pptp project (https://sourceforge.net/projects/accel-pptp/) to utilize this module, it contains plugin for pppd to use pptp in client-mode and modified pptpd (poptop) to build high-performance pptp NAS. There was many changes from initial submitted patch, most important are: 1. using rcu instead of read-write locks 2. using static bitmap instead of dynamically allocated 3. using vmalloc for memory allocation instead of BITS_PER_LONG + __get_free_pages 4. fixed many coding style issues Thanks to Eric Dumazet.
