[ Upstream commit1d8e801422] While executing the Android 13 CTS Verifier Secure Server test on a ChromeOS device, it was observed that the Bluetooth host initiates authentication for an RFCOMM connection after SSP completes. When this happens, some Intel Bluetooth controllers, like AC9560, would disconnect with "Connection Rejected due to Security Reasons (0x0e)". Historically, BlueZ did not mandate this authentication while an authenticated combination key was already in use for the connection. This behavior was changed since commit7b5a9241b7("Bluetooth: Introduce requirements for security level 4"). So, this patch addresses the aforementioned disconnection issue by restoring the previous behavior.

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.
