Comment 12 for bug 1298611

Here is a debdiff for lxc. It is tested on trusty. To ease backporting, I updated debian/rules for strip out the signal and ptrace rules for Ubuntu releases earlier than 14.04 (using the same method as for stripping out dbus for earlier than 13.10), but could not test earlier releases because libcgmanager-dev does not exist on them.

Before upgrading lxc, there were many ptrace and signal denials when using containers. After upgrading, creating, starting, using, stopping, destroying all works fine with no denials.
