[ Upstream commit0318a7b7fc] In the two places is_last_ethertype_ip is being called, the caller will be looking inside the ip header, to be safe, add ip{4,6} header sanity check. And return true only on valid ip headers, i.e: the whole header is contained in the linear part of the skb. Note: Such situation is very rare and hard to reproduce, since mlx5e allocates a large enough headroom to contain the largest header one can imagine.

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.
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.
