[Bug 930652] Re: lxc & swapoff: Not superuser
We're not going to fix this in LXC as the failure is obviously intended. However with lxcfs we can now render /proc/swaps in a more consistent way, including hiding swap for containers which shouldn't have any swap access. ** Changed in: lxc (Ubuntu) Status: Confirmed => Won't Fix -- 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/930652 Title: lxc & swapoff: Not superuser To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/930652/+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
[Bug 930652] Re: lxc swapoff: Not superuser
Thanks for reporting this bug. I see the message too. Of course the failure to unmount swap is a good thing :) I'll assume the real bug, as perceived, is that the container thinks it has something to swapoff. Fixing that will require /proc contents filtering. We can use the apparmor policy to deny read access to /proc/swaps, which replaces the error with /etc/rc0.d/S35networking: 61: /etc/rc0.d/S35networking: cannot open /proc/swaps: Permission denied * Deactivating swap... [ OK ] Another possibility of course is for /etc/rc0.d/S35networking to detect it is in a container and not try to swapoff. However, as no harm is being done to the container or the host, Im going to mark this wishlist for now. ** Changed in: lxc (Ubuntu) Status: New = Confirmed ** Changed in: lxc (Ubuntu) Importance: Undecided = Low ** Changed in: lxc (Ubuntu) Importance: Low = Wishlist -- 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/930652 Title: lxc swapoff: Not superuser To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/930652/+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
