[ Upstream commit efaf24e30ec39ebbea9112227485805a48b0ceb1 ]
While dumping sockets via UNIX_DIAG, we do not hold unix_state_lock().
Let's use READ_ONCE() to read sk->sk_shutdown.
Fixes: e4e541a848 ("sock-diag: Report shutdown for inet and unix sockets (v2)")

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.
