David reported breakages of VRF scenarios due to the commit6e617de84e("net: avoid a full fib lookup when rp_filter is disabled."): the local addresses based test is too strict when VRFs are in place. With this change we fall-back to a full lookup when custom fib rules are in place; so that we address the VRF use case and possibly other similar issues in non trivial setups. v1 -> v2: - fix build breakage when CONFIG_IP_MULTIPLE_TABLES is not defined, reported by the kbuild test robot Reported-by: David Ahern <dsahern@gmail.com> Fixes:6e617de84e("net: avoid a full fib lookup when rp_filter is disabled.")

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.
