[ Upstream commit af4c733b6b1aded4dc808fafece7dfe6e9d2ebb3 ]
unix_stream_read_skb() is called from sk->sk_data_ready() context
where unix_state_lock() is not held.
Let's use READ_ONCE() there.
Fixes: 77462de14a ("af_unix: Add read_sock for stream socket types")

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.
