Public bug reported:
Hello,
I am using latest stables lxc build from
http://ppa.launchpad.net/ubuntu-lxc/stable/ubuntu on a OpenStack controller to
run containers. The OpenStack is also using network namespaces . When I boot
the server without auto start the containers everything looks fine with the
OpenStack network namespaces. If I boot lxc container with lxc-start the
container starts and its networking is functioning, but network namespaces
created before that , by OpenStack installation for example , become unusable
with he following error:
root@osctrl3dc02:~# ip netns exec vips ip a
seting the network namespace failed: Invalid argument
Here is the strace:
open("/var/run/netns/vips", O_RDONLY) = 4
syscall_308(0x4, 0x40000000, 0x7fffc4d54e83, 0x7fffc4d54bf0, 0x430af0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0) = -1 (errno 22)
As far as I know sys call_308 should set the namespace , but it seems
it fails on accessing the /var/run/netns/vips
It is strange that the permissions are altered:
root@osctrl3dc02:~# ls -alh /var/run/netns/vips
---------- 1 root root 0 Apr 14 08:48 /var/run/netns/vips
This file have the following permission before I start the container
-r--r--r-- 1 root root 0 Apr 12 14:01 /var/run/netns/vips
If I destroy the vips namespace and create it again , keeping the lxc
containers running, everything is back to normal, both containers and
Openstack networking are working.
Best regards,
