<content type='text'>
The 'comp' compression API has been superseded by the acomp API, which
is a bit more cumbersome to use, but ultimately more flexible when it
comes to hardware implementations.

Now that all the users and implementations have been removed, let's
remove the core plumbing of the 'comp' API as well.

Separate out the HKDF functions into a separate module to
to make them available to other callers.
And add a testsuite to the module with test vectors
from RFC 5869 (and additional vectors for SHA384 and SHA512)
to ensure the integrity of the algorithm.

<title>crypto: Add 'krb5enc' hash and cipher AEAD algorithm</title>

<name>David Howells</name>

<id>d1775a177f7f38156d541c8a3e3c91eaa6e69699</id>
<content type='text'>
Add an AEAD template that does hash-then-cipher (unlike authenc that does
cipher-then-hash).  This is required for a number of Kerberos 5 encoding
types.

[!] Note that the net/sunrpc/auth_gss/ implementation gets a pair of
ciphers, one non-CTS and one CTS, using the former to do all the aligned
blocks and the latter to do the last two blocks if they aren't also
aligned.  It may be necessary to do this here too for performance reasons -
but there are considerations both ways:

 (1) firstly, there is an optimised assembly version of cts(cbc(aes)) on
     x86_64 that should be used instead of having two ciphers;

 (2) secondly, none of the hardware offload drivers seem to offer CTS
     support (Intel QAT does not, for instance).

However, I don't know if it's possible to query the crypto API to find out
whether there's an optimised CTS algorithm available.

<title>crypto: crct10dif - remove from crypto API</title>

<id>8522104f75bf1ce33d76ea425185da2a7fba5a70</id>
<content type='text'>
Remove the "crct10dif" shash algorithm from the crypto API.  It has no
known user now that the lib is no longer built on top of it.  It has no
remaining references in kernel code.  The only other potential users
would be the usual components that allow specifying arbitrary hash
algorithms by name, namely AF_ALG and dm-integrity.   However there are
no indications that "crct10dif" is being used with these components.
Debian Code Search and web searches don't find anything relevant, and
explicitly grepping the source code of the usual suspects (cryptsetup,
libell, iwd) finds no matches either.  "crc32" and "crc32c" are used in
a few more places, but that doesn't seem to be the case for "crct10dif".

crc_t10dif_update() is also tested by crc_kunit now, so the test
coverage provided via the crypto self-tests is no longer needed.

Also note that the "crct10dif" shash algorithm was inconsistent with the
rest of the shash API in that it wrote the digest in CPU endianness,
making the resulting byte array differ on little endian vs. big endian
platforms.  This means it was effectively just built for use by the lib
functions, and it was not actually correct to treat it as "just another
hash function" that could be dropped in via the shash API.

<title>crypto: crc64-rocksoft - remove from crypto API</title>

<id>0fcec0b73adc5f86597d342062114b77bcf7ec9d</id>
<content type='text'>
Remove crc64-rocksoft from the crypto API.  It has no known user now
that the lib is no longer built on top of it.  It was also added much
more recently than the longstanding crc32 and crc32c.  Unlike crc32 and
crc32c, crc64-rocksoft is also not mentioned in the dm-integrity
documentation and there are no references to it in anywhere in the
cryptsetup git repo, so it is unlikely to have any user there either.

Also, this CRC variant is named incorrectly; it has nothing to do with
Rocksoft and should be called crc64-nvme.  That is yet another reason to
remove it from the crypto API; we would not want anyone to start
depending on the current incorrect algorithm name of crc64-rocksoft.

Note that this change temporarily makes this CRC variant not be covered
by any tests, as previously it was relying on the crypto self-tests.
This will be fixed by adding this CRC variant to crc_kunit.

<title>crypto: keywrap - remove unused keywrap algorithm</title>

The keywrap (kw) algorithm has no in-tree user.  It has never had an
in-tree user, and the patch that added it provided no justification for
its inclusion.  Even use of it via AF_ALG is impossible, as it uses a
weird calling convention where part of the ciphertext is returned via
the IV buffer, which is not returned to userspace in AF_ALG.

It's also unclear whether any new code in the kernel that does key
wrapping would actually use this algorithm.  It is controversial in the
cryptographic community due to having no clearly stated security goal,
no security proof, poor performance, and only a 64-bit auth tag.  Later
work (https://eprint.iacr.org/2006/221) suggested that the goal is
deterministic authenticated encryption.  But there are now more modern
algorithms for this, and this is not the same as key wrapping, for which
a regular AEAD such as AES-GCM usually can be (and is) used instead.

Therefore, remove this unused code.

There were several special cases for this algorithm in the self-tests,
due to its weird calling convention.  Remove those too.
