Jens Axboe d624594445 net: disallow ancillary data for __sys_{send,recv}msg_file()
[ Upstream commit d69e07793f891524c6bbf1e75b9ae69db4450953 ]

Only io_uring uses (and added) these, and we want to disallow the
use of sendmsg/recvmsg for anything but regular data transfers.
Use the newly added prep helper to split the msghdr copy out from
the core function, to check for msg_control and msg_controllen
settings. If either is set, we return -EINVAL.

README

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.
