This should be fixed in lxc in precise, where the apparmor policy should prevent it from happening. I've marked the kernel bug invalid, but kept the binfmt-support bug new.

@Andy -- that depends on whether we consider the kernel part of this a bug or not. For lxc it'll be fixed with an apparmor policy shipped with lxc. For update-binfmts more generally, there might be way for that program to be smarter. But still the kernel itself is reading over proc and/or sys files, so there's the question of how far we go to protect the admin from himself.

Thank you for taking the time to file a bug report on this issue. However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request. We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not. You can update to the latest development kernel by simply running the following commands in a terminal window: sudo apt-get update sudo apt-get upgrade If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released. If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging.

Thanks, Guilherme. I'm sorry, should have mentioned that no, a new kernel was not expected to fix that. For lxc containers, we can (and should) fix this using an apparmor policy.

[Bug 917660] Re: Installing qemu-user-static in an i386 lxc container applies the binfmt changes to the host, breaking execution in that host
Thanks, Guilherme. I'm sorry, should have mentioned that no, a new kernel was not expected to fix that. For lxc containers, we can (and should) fix this using an apparmor policy. I don't know if there is a reasonable way that update-binfmts itself can detect this. I'll mark this as affecting that package to get more input. ** Also affects: binfmt-support (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/917660 Title: Installing qemu-user-static in an i386 lxc container applies the binfmt changes to the host, breaking execution in that host To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/binfmt-support/+bug/917660/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Is the new kernel still on -proposed or has it been accepted already? I just ran apt-get update/upgrade and didn't get that.

Thank you for taking the time to file a bug report on this issue. However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request. We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not. You can update to the latest development kernel by simply running the following commands in a terminal window: sudo apt-get update sudo apt-get upgrade If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released. If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging. Thank you for your help, we really do appreciate it. ** Changed in: linux (Ubuntu) Status: Confirmed = Incomplete ** Tags added: kernel-request-3.2.0-10.17 -- 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/917660 Title: Installing qemu-user-static in an i386 lxc container applies the binfmt changes to the host, breaking execution in that host To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/917660/+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
