Split conditions, so that each test becomes clearer. Also, for l2tp_ip, check if "laddr" is 0. This prevents a socket from binding to the unspecified address when other sockets are already bound using the same device (if any), connection ID and namespace. Same thing for l2tp_ip6: add ipv6_addr_any(laddr) and ipv6_addr_any(raddr) tests to ensure that an IPv6 unspecified address passed as parameter is properly treated a wildcard.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
