Kees Cook 7086619922 net: qed: Fix memcpy() overflow of qed_dcbx_params()
[ Upstream commit 1c200f832e14420fa770193f9871f4ce2df00d07 ]

The source (&dcbx_info->operational.params) and dest
(&p_hwfn->p_dcbx_info->set.config.params) are both struct qed_dcbx_params
(560 bytes), not struct qed_dcbx_admin_params (564 bytes), which is used
as the memcpy() size.

However it seems that struct qed_dcbx_operational_params
(dcbx_info->operational)'s layout matches struct qed_dcbx_admin_params
(p_hwfn->p_dcbx_info->set.config)'s 4 byte difference (3 padding, 1 byte
for "valid").

On the assumption that the size is wrong (rather than the source structure
type), adjust the memcpy() size argument to be 4 bytes smaller and add
a BUILD_BUG_ON() to validate any changes to the structure sizes.

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 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.
