[ Upstream commit680f6af533] If userspace provides a rule blob with trailing data after last target, we trigger a splat, then convert ruleset to 64bit format (with trailing data), then pass that to do_replace_finish() which then returns -EINVAL. Erroring out right away avoids the splat plus unneeded translation and error unwind.

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.
