Message-ID: <527D2768.1030403@canonical.com> Date: Fri, 08 Nov 2013 12:03:20 -0600 From: Chris J Arges <chris.j.arges@...onical.com> To: shemminger@...l.org, netdev@...r.kernel.org Subject: iproute2: potential upgrade regression with 58a3e827 Hi, The commit https://git.kernel.org/cgit/linux/kernel/git/shemminger/iproute2.git/commit/?id=58a3e8270fe72f8ed92687d3a3132c2a708582dd could be potentially introducing a regression on an upgrade. I've noticed that upgrading iproute while there are active namespaces could cause the following error: seting the network namespace failed: Invalid argument Here's a test case: Build and install iproute2 with 4395d48c78a77a99c5a8618403211032356fe552 In one terminal run: ip netns add netns_old ip link add name if_old type veth peer name if_old_peer ip link set dev if_old_peer netns netns_old ip netns exec netns_old bash Build and install iproute2 with 58a3e8270fe72f8ed92687d3a3132c2a708582dd In the same terminal as you typed the original commands run: ip netns add netns_one ip link add name if_one type veth peer name if_one_peer ip link set dev if_one_peer netns netns_one ip netns exec netns_one bash ip netns exec netns_old bash You'll get: seting the network namespace failed: Invalid argument If you just run the above without transitioning to the code in 58a3e827, then it works.
