commit2aa39889c4upstream Commit3ea566422c("can: isotp: sanitize CAN ID checks in isotp_bind()") checks the given CAN ID address information by sanitizing the input values. This check (silently) removes obsolete bits by masking the given CAN IDs. Derek Will suggested to give a feedback to the application programmer when the 'sanitizing' was actually needed which means the programmer provided CAN ID content in a wrong format (e.g. SFF CAN IDs with a CAN ID > 0x7FF).

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.
