Subject: Re: iproute2 for 3.0

 Just tested git iproute2 and 3.0-rc7-git1

 Tested if namespaces working:
 Tunnel ~ # uname -a
 Linux Tunnel 3.0.0-rc7-git1-build-0060 #2 SMP Thu Jul 14 13:06:32 EEST 
 2011 i686 GNU/Linux
 Tunnel ~ # unshare -n ip addr
 3: lo: <LOOPBACK> mtu 16436 qdisc noop state DOWN
     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
 Tunnel ~ # ip addr
 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
     inet 127.0.0.1/8 scope host lo
 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast 
 state UP qlen 1000
     link/ether 00:1c:c0:d3:d8:db brd ff:ff:ff:ff:ff:ff
     inet 192.168.20.20/24 scope global eth0
 Tunnel ~ #

 Then tried to used new commands:

 Tunnel ~ # ip netns add test
 Tunnel ~ # ip netns list
 test
 Tunnel ~ # ip netns exec test ls
 seting the network namespace failed: Function not implemented

 I did small patch, cause 3.0 kernel headers not distro repository yet:
 #define NETNS_ETC_DIR "/etc/netns"
 
 +#define __NR_setns 268
 
 #ifndef CLONE_NEWNET

 But still it is not working:
 Tunnel ~ # ip netns exec test /bin/sh
 fd 4 nstype 1073741824|40000000
 seting the network namespace failed: Invalid argument
