[ Upstream commit405b93eb76] The current ARFS code relies on certain fields to be set in the SKB (e.g. transport_header) and extracts IP addresses and ports by custom code that parses the packet. The necessary SKB fields, however, are not always set at that point, which leads to an out-of-bounds access. Use skb_flow_dissect_flow_keys() to get the necessary information reliably, fix the out-of-bounds access and reuse the code.

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.
