Add helper to check netlink message for route dumps. If the strict flag is set the dump request is expected to have an rtmsg struct as the header. All elements of the struct are expected to be 0 with the exception of rtm_flags (which is used by both ipv4 and ipv6 dumps) and no attributes can be appended. rtm_flags can only have RTM_F_CLONED and RTM_F_PREFIX set. Update inet_dump_fib, inet6_dump_fib, mpls_dump_routes, ipmr_rtm_dumproute, and ip6mr_rtm_dumproute to call this helper if strict data checking is enabled.

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.
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.
