Public bug reported:


the VM kernel crash when a user execute the following command :
/sbin/ip link show dev eth0

The kernel used is 3.0.8 with the marionnet patch.

An odd behaviour : If the VM kernel is executed under root (directly the
uml kernel, without marionnet) it works ; if the VM kernel is executed
under another user, it crash.

This command "/sbin/ip link show dev eth0" is used by the ifup script when there it try to setup a vlan interface.
For example if /etc/network/interfaces is :

iface eth0 inet static
address 10.10.10.1
netmask 255.255.255.0

iface eth0.100 inet static
address 10.10.20.1
netmask 255.255.255.0

when the command "ifup eth0.100" is executed the kernel crash.
