Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.

Now, register_pernet_subsys() and register_netdevice_notifier() are both after sock_register(). It can create PF_PACKET socket and process socket once sock_register() successfully. It is possible PF_PACKET socket is creating but register_pernet_subsys() and register_netdevice_notifier() are not registered yet. Thus net->packet.sklist_lock and net->packet.sklist will be accessed without initialization that is done in packet_net_init(). Although this is a low probability scenario. Move register_pernet_subsys() and register_netdevice_notifier() to the front in packet_init(). Correspondingly, adjust the unregister process in packet_exit().
