mainlining shenanigans

The MPTCP protocol uses a specific protocol value, even if it's an extension to TCP. Additionally, MPTCP sockets could 'fall-back' to TCP at run-time, depending on peer MPTCP support and available resources. As a consequence of the specific protocol number, selinux applies the raw_socket class to MPTCP sockets. Existing TCP application converted to MPTCP - or forced to use MPTCP socket with user-space hacks - will need an updated policy to run successfully. This change lets selinux attach the TCP socket class to MPTCP sockets, too, so that no policy changes are needed in the above scenario. Note that the MPTCP is setting, propagating and updating the security context on all the subflows and related request socket.

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.
