Daniel Axtens 3b52ada5b8 crypto: vmx - reject xts inputs that are too short 
commit 1372a51b88fa0d5a8ed2803e4975c98da3f08463 upstream.

When the kernel XTS implementation was extended to deal with ciphertext
stealing in commit 8083b1bf81 ("crypto: xts - add support for ciphertext
stealing"), a check was added to reject inputs that were too short.

However, in the vmx enablement - commit 2396684193 ("crypto: vmx/xts -
use fallback for ciphertext stealing"), that check wasn't added to the
vmx implementation. This disparity leads to errors like the following:

alg: skcipher: p8_aes_xts encryption unexpectedly succeeded on test vector "random: len=0 klen=64"; expected_error=-22, cfg="random: inplace may_sleep use_finup src_divs=[<flush>66.99%@+10, 33.1%@alignmask+1155]"

Return -EINVAL if asked to operate with a cryptlen smaller than the AES
block size. This brings vmx in line with the generic implementation.

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.
