This solves the following issues observed during self test when CONFIG_CRYPTO_MANAGER_EXTRA_TESTS is enabled. 1. Added fallback for cbc, ctr and rfc3686 if req->nbytes is zero and for xts added a fallback case if req->nbytes is not multiple of 16. 2. In case of cbc-aes, solved wrong iv update. When chcr_cipher_fallback() is called, used req->info pointer instead of reqctx->iv. 3. In cbc-aes decryption there was a wrong result. This occurs when chcr_cipher_fallback() is called from chcr_handle_cipher_resp(). In the fallback function iv(req->info) used is wrongly updated. So use the initial iv for this case. 4)In case of ctr-aes encryption observed wrong result. In adjust_ctr_overflow() there is condition which checks if ((bytes / AES_BLOCK_SIZE) > c), where c is the number of blocks which can be processed without iv overflow, but for the above bytes (req->nbytes < 32 , not a multiple of 16) this condition fails and the 2nd block is corrupted as it requires the rollover iv. So added a '=' condition in this to take care of this. 5)In rfc3686-ctr there was wrong result observed. This occurs when chcr_cipher_fallback() is called from chcr_handle_cipher_resp(). Here also copying initial_iv in init_iv pointer for handling the fallback case correctly.

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.
