Trond Myklebust 7dbee046e2 SUNRPC: Do not dereference non-socket transports in sysfs 
[ Upstream commit 421ab1be43 ]

Do not cast the struct xprt to a sock_xprt unless we know it is a UDP or
TCP transport. Otherwise the call to lock the mutex will scribble over
whatever structure is actually there. This has been seen to cause hard
system lockups when the underlying transport was RDMA.

Fixes: b49ea673e1 ("SUNRPC: lock against ->sock changing during sysfs read")

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.
