====================
mptcp: fix sockopt crash and lockdep splats

Christoph Paasch reported a few bugs and lockdep splats triggered by
syzkaller.

One patch fixes a crash in set/getsockopt.
Two patches fix lockdep splats related to the order in which RTNL
and socket lock are taken.

Last patch fixes out-of-bounds access when TCP syncookies are used.

Change since last iteration on mptcp-list:
 - add needed refcount in patch 2
 - call tcp_get/setsockopt directly in patch 2

 Other patches unchanged except minor amends to commit messages.

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.
