hi,

I am trying to create a network namespace with a vethX device in it and
a special qdisc but without much luck. I wonder if this is something
which is unsupported or is just a bug.

[mathieu@mathieu-laptop netns]$ uname -a
Linux mathieu-laptop 2.6.30.5-43.fc11.x86_64 #1 SMP Thu Aug 27 21:39:52
EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

shell in default namespace:

[mathieu@mathieu-laptop netns]$ sudo ip link add type veth
[mathieu@mathieu-laptop netns]$ sudo tc qdisc add dev veth0 root netem
delay 100ms
[mathieu@mathieu-laptop netns]$ sudo ip link set dev veth0 netns 3104
[mathieu@mathieu-laptop netns]$ 


shell in other network namespace:

[mathieu@mathieu-laptop netns]$ sudo ./netunshare /bin/bash
[sudo] password for mathieu: 
[root@mathieu-laptop netns]# echo $$
3104
[root@mathieu-laptop netns]# sudo ip link show veth0
11: veth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen
1000
    link/ether 9a:bb:18:b6:1b:06 brd ff:ff:ff:ff:ff:ff
[root@mathieu-laptop netns]# sudo tc qdisc add dev veth0 root netem
delay 100ms
RTNETLINK answers: Invalid argument
[root@mathieu-laptop netns]# 

any kind of idea would be welcome.

Mathieu
