So the particular files /var/run/netns/whatzit are bind-mounted /proc/self/ns/net files from a task which no longer exists, which are pinning the netns.
Interestingly, if I reproduce this by hand by doing term 1: lxc-unshare -s NETWORK -- /bin/bash term 2: mkdir /var/run/netns/z; mount --bind /proc/$pid/net/ns /var/run/netns/z lxc-start -n t1 -d; sleep 3; lxc-stop -n t1 -k then /var/run/netns/z permissions are not changed. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1307829 Title: network namespace error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/iproute/+bug/1307829/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
