Kery Qi a42bdbcada scsi: firewire: sbp-target: Fix overflow in sbp_make_tpg() 
[ Upstream commit b2d6b1d443 ]

The code in sbp_make_tpg() limits "tpgt" to UINT_MAX but the data type of
"tpg->tport_tpgt" is u16. This causes a type truncation issue.

When a user creates a TPG via configfs mkdir, for example:

    mkdir /sys/kernel/config/target/sbp/<wwn>/tpgt_70000

The value 70000 passes the "tpgt > UINT_MAX" check since 70000 is far less
than 4294967295. However, when assigned to the u16 field tpg->tport_tpgt,
the value is silently truncated to 4464 (70000 & 0xFFFF). This causes the
value the user specified to differ from what is actually stored, leading to
confusion and potential unexpected behavior.

Fix this by changing the type of "tpgt" to u16 and using kstrtou16() which
will properly reject values outside the u16 range.

README 

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 reStructuredText 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.
