When the network namespace is deleted, the net structure\naccessed by tcp\u0027s timer handler function causes problems.\n\nTo fix this problem, let\u0027s hold netns refcnt for the tcp kernel socket as\ndone in other modules. This is an ugly hack which can easily be backported\nto earlier kernels. A proper fix which cleans up the interfaces will\nfollow, but may not be so easy to backport.",

For example, qfq_dump_class may trigger a NULL\ndereference, and qfq_delete_class may cause a use-after-free.\n\nThis patch addresses the issue by:\n\n1.
