Eric Biggers 0b1871d041 crypto: cfb - add missing 'chunksize' property 
commit 394a9e0447 upstream.

Like some other block cipher mode implementations, the CFB
implementation assumes that while walking through the scatterlist, a
partial block does not occur until the end.  But the walk is incorrectly
being done with a blocksize of 1, as 'cra_blocksize' is set to 1 (since
CFB is a stream cipher) but no 'chunksize' is set.  This bug causes
incorrect encryption/decryption for some scatterlist layouts.

Fix it by setting the 'chunksize'.  Also extend the CFB test vectors to
cover this bug as well as cases where the message length is not a
multiple of the block size.

Fixes: a7d85e06ed ("crypto: cfb - add support for Cipher FeedBack mode")

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.
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.
