Florian Westphal b668af6732 netfilter: nft_set_hash: fix get operation on big endian
[ Upstream commit 2f635adbe2 ]

tests/shell/testcases/packetpath/set_match_nomatch_hash_fast
fails on big endian with:

Error: Could not process rule: No such file or directory
reset element ip test s { 244.147.90.126 }
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Fatal: Cannot fetch element "244.147.90.126"

... because the wrong bucket is searched, jhash() and jhash1_word are
not interchangeable on big endian.

Fixes: 3b02b0adc2 ("netfilter: nft_set_hash: fix lookups with fixed size hash on big endian")

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.
