Hi,
Linux 2.6.28 is likely nearing release so with a bit of prodding
from Joseph Mack I thought this would be a good time to let
everyone know about a few significant changes to LVS (aka IPVS)
that will be included in 2.6.28.
LVS IPV6
--------
>From 2.6.28 LVS will support IPv6 thanks to work by Julis Volz
and Vince Busam.
In order to use the IPV6 functionality, a new version of ipvsadm is needed.
It is based on the new netlink API for LVS kernel - user-space
communication. This version of ipvsam is a fork of the main ipvsadm code
and was written by Vince Busam and can be found at.
http://sixpak.org/vince/google/ipvsadm/
There are loose plans to merge this code into the main ipvsadm relese,
but there has been little activity on this of late.
Wensong gave Vince, Julius and myself write access to the ipvsadm
svn repository, but I don't believe that anyone has merged the code.
Vince's version of ipvsadm can also configure IPV4.
And the 2.6.28 kernel can work work old versions of ipvsadm - its
just that user's won't be able to configure IPV6 LVS with the older tool.
IPVS under Netfilter
--------------------
A related change, of note is that ipvs has moved from net/ipv4/ipvs
to net/netfilter/ipvs. This means that when you are using make menuconfig
(or similar) the configuration for IPVS has moved and is now
under the Netfilter menu. This does not effect using IPVS, just
configuring the kernel configuration.
This has not resulted in any restructuring of the code,
the code has just been moved as now that it supports IPV6 it
seemed a little odd for it to live under net/ipv4/.
Local Connections
-----------------
The change by Malcolm Turnbull and Siim Põder added support to allow
connections from a local process to be load balanced.
ChangeLog
---------
For the record, here is a list of changes (matching IPVS) since 2.6.27.
I don't anticipate anything more going into 2.6.28 unless a bug shows up.

netfilter: enable netfilter in netns
From kernel perspective, allow entrance in nf_hook_slow().
Stuff which uses nf_register_hook/nf_register_hooks, but otherwise not
netns-ready:
DECnet netfilter
ipt_CLUSTERIP
nf_nat_standalone.c together with XFRM (?)
IPVS
several individual match modules (like hashlimit)
ctnetlink
NOTRACK
all sorts of queueing and reporting to userspace
L3 and L4 protocol sysctls, bridge sysctls
probably something else
Anyway critical mass has been achieved, there is no reason to hide
netfilter any longer.
From userspace perspective, allow to manipulate all sorts of
iptables/ip6tables/arptables rules.

netfilter: netns: fix {ip,6}_route_me_harder() in netns
Take netns from skb->dst->dev. It should be safe because, they are called

IPVS and queueing packets to userspace).

IPVS: Move IPVS to net/netfilter/ipvs
Since IPVS now has partial IPv6 support, this patch moves IPVS from
net/ipv4/ipvs to net/netfilter/ipvs. It's a result of:
$ git mv net/ipv4/ipvs net/netfilter
and adapting the relevant Kconfigs/Makefiles to the new path.

happen during unload of IPVS, because during normal operation there is at
least
our global stats structure in the estimator list. The mod_timer() and

disguise. Let's make it explicit and move them to their own init and cleanup
function.
