Dean Jenkins e163376220 Bluetooth: Handle bt_accept_enqueue() socket atomically
There is a small risk that bt_accept_unlink() runs concurrently with
bt_accept_enqueue() on the same socket. This scenario could potentially
lead to a NULL pointer dereference of the socket's parent member because
the socket can be on the list but the socket's parent member is not yet
updated by bt_accept_enqueue().

Therefore, add socket locking inside bt_accept_enqueue() so that the
socket is added to the list AND the parent's socket address is set in the
socket's parent member. The socket locking ensures that the socket is on
the list with a valid non-NULL parent member.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
