[PATCH 0/3] IPVS full NAT support + netfilter 'ipvs' match support

[Hannes Eder]

The following series implements full NAT support for IPVS.  The
approach is via a minimal change to IPVS (make friends with
nf_conntrack) and adding a netfilter matcher, kernel- and user-space
part, i.e. xt_ipvs and libxt_ipvs.

Example usage:

% ipvsadm -A -t 192.168.100.30:8080 -s rr
% ipvsadm -a -t 192.168.100.30:8080 -r 192.168.10.20:8080 -m
# ...

# Source NAT for VIP 192.168.100.30:8080
% iptables -t nat -A POSTROUTING -m ipvs --vaddr 192.168.100.30/32 --vport 8080 \
> -j SNAT --to-source 192.168.10.10
