The hmac template is setting its alignmask to that of its underlying unkeyed hash algorithm, and it is aligning the ipad and opad fields in its tfm context to that alignment. However, hmac does not actually need any sort of alignment itself, which makes this pointless except to keep the pads aligned to what the underlying algorithm prefers. But very few shash algorithms actually set an alignmask, and it is being removed from those remaining ones; also, after setkey, the pads are only passed to crypto_shash_import and crypto_shash_export which ignore the alignmask. Therefore, make the hmac template stop setting an alignmask and simply use natural alignment for ipad and opad. Note, this change also moves the pads from the beginning of the tfm context to the end, which makes much more sense; the variable-length fields should be at the end.

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.
