+First steps towards the next generation netfilter subsystem
+
+Until 2.6, every new kernel version came with its own incarnation of a packet
+filter: ipfw, ipfwadm, ipchains, iptables.  2.6.x still had iptables.  What was
+wrong?  Or was iptables good enough to last even two generations?
+
+In reality the netfilter project is working on gradually transforming the
+existing framework into something new.  Some of those changes are transparent
+to the user, so they slip into a kernel release almost unnoticed.  However, 
+for expert users and developers those changes are noteworthy anyway.
+
+Some other changes just extend the existing framework, so most users again
+won't even notice them - they just don't take advantage of those new features.
+
+The 2.6.14 kernel release will mark a milestone, since it is scheduled to
+contain nfnetlink, ctnetlink, nfnetlink_queue and nfnetlink_log - basically a
+totally new netlink-based kernel/userspace interface for most parts of the
+netfilter subsystem.
+
+nf_conntrack, a generic layer-3 independent connection tracking subsystem,
+initially supporting IPv4 and IPv6, is also in the queue of pending patches.
+Chances are high that it will be included in the mainline kernel at the time
+this paper is presented at Linux Kongress.
+
+Another new subsystem within the framework is the "ipset" filter, basically an
+alternative to using iptables in certain areas.
+
+The presentation will cover a timeline of recent advances in the netfilter
+world, and describe each of the new features in detail.  It will also summarize
+the results of the annual netfilter development workshop, which is scheduled
+just the week before Linux Kongress.

+  Harald Welte is the chairman of the netfilter/iptables core team.
+
+  His main interest in computing has always been networking.  In the few time
+left besides netfilter/iptables related work, he's writing obscure documents
+like the "UUCP over SSL HOWTO" or "A packet's journey through the Linux network
+stack".  Other kernel-related projects he has been contributing to are random
+netowrking hacks, some device driver work and the neighbour cache.
+
+  He has been working as an independent IT Consultant working on projects for
+various companies ranging from banks to manufacturers of networking gear.
+During the year 2001 he was living in Curitiba (Brazil), where he got
+sponsored for his Linux related work by Conectiva Inc.
+
+  Starting with February 2002, Harald has been contracted part-time by
+Astaro AG, who are sponsoring him for his current netfilter/iptables work.
+Aside from the Astaro sponsoring, he continues to work as a freelancing kernel
+developer and network security consultant.
+
+  He licenses his software under the terms of the GNU GPL.  Sometimes users of
+his software are not compliant with the license, so he started enforcing the
+GPL with his gpl-violations.org project.
+
+  During the last year, Harald has started development of a free, GPL-licensed
+Linux RFID and electronic passport software suite.
+
+Harald is living in Berlin, Germany.
