Only platforms which compat to "i386" have the issue wrt.

- Because the directing of packets is based on ip address and multiple
network namespaces are allowed to use the same ip addresses then
the decode needs to take the network namespace into account.
Hm, but a tunnel device can belong to only one namespace, so shouldn't this
get handled automa
Hi Eric,
Are the current semantics of tunnel devices (ipip, ip_gre etc.) with
respect to changing the current netns correct? These devices have an
ip_tunnel structure associated with each net_device, which is
currently a global (not per_net). The result is that you can set up in
container X a tun

I sent one just
Untested.
dup_mnt_ns() and clone_uts_ns() return NULL on failure. This is wrong,
create_new_namespaces() uses ERR_PTR() to catch an error. This means
that the subsequent create_new_namespaces() will hit BUG_ON() in
copy_mnt_ns() or copy_utsname().

Hi all,
The network namespace patchset has been ported to 2.6.21-mm2.
They are still some issues but we are on it, for this reason the
patchset is named netns1-beta1.
The patchset can be found here :
http://lxc.sourceforge.net/patches/2.6.21/2.6.21-mm2-netns1-beta1/
Documentation can be fou

OK. We have measured the nptl perf test for init namespace.
Summary - flat model is very light, Suka's patches break the
kernel performance event when CONFIG_PID_NS is off.
