Eric Biggers ee1c6b1aa9 crypto: testmgr - don't try to decrypt uninitialized buffers
commit eb455dbd02cb1074b37872ffca30a81cb2a18eaa upstream.

Currently if the comparison fuzz tests encounter an encryption error
when generating an skcipher or AEAD test vector, they will still test
the decryption side (passing it the uninitialized ciphertext buffer)
and expect it to fail with the same error.

This is sort of broken because it's not well-defined usage of the API to
pass an uninitialized buffer, and furthermore in the AEAD case it's
acceptable for the decryption error to be EBADMSG (meaning "inauthentic
input") even if the encryption error was something else like EINVAL.

Fix this for skcipher by explicitly initializing the ciphertext buffer
on error, and for AEAD by skipping the decryption test on error.

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.
