46b3ff73af crypto: sm2 - Remove sm2 algorithm
The SM2 algorithm has a single user in the kernel.  However, it's
never been integrated properly with that user: asymmetric_keys.

The crux of the issue is that the way it computes its digest with
sm3 does not fit into the architecture of asymmetric_keys.  As no
solution has been proposed, remove this algorithm.

It can be resubmitted when it is integrated properly into the
asymmetric_keys subsystem.

203a6763ab Revert "crypto: pkcs7 - remove sha1 support"
This reverts commit 16ab7cb582 because it
broke iwd.  iwd uses the KEYCTL_PKEY_* UAPIs via its dependency libell,
and apparently it is relying on SHA-1 signature support.  These UAPIs
are fairly obscure, and their documentation does not mention which
algorithms they support.  iwd really should be using a properly
supported userspace crypto library instead.  Regardless, since something
broke we have to revert the change.

It may be possible that some parts of this commit can be reinstated
without breaking iwd (e.g. probably the removal of MODULE_SIG_SHA1), but
for now this just does a full revert to get things working again.

16ab7cb582 crypto: pkcs7 - remove sha1 support
Removes support for sha1 signed kernel modules, importing sha1 signed
x.509 certificates.

rsa-pkcs1pad keeps sha1 padding support, which seems to be used by
virtio driver.

sha1 remains available as there are many drivers and subsystems using
it. Note only hmac(sha1) with secret keys remains cryptographically
secure.

In the kernel there are filesystems, IMA, tpm/pcr that appear to be
using sha1. Maybe they can all start to be slowly upgraded to
something else i.e. blake3, ParallelHash, SHAKE256 as needed.

Changes from v1:
  * replace some accidental spaces with tabs

In commit f145d411a6 ("crypto: rsa - implement Chinese Remainder Theorem
for faster private key operations") we have started to use the additional
primes and coefficients for RSA private key operations. However, these
additional parameters are not present (defined as 0 integers) in the RSA
test vectors.

Some parameters were borrowed from OpenSSL, so I was able to find the
source. I could not find the public source for 1 vector though, so had to
recover the parameters by implementing Appendix C from [1].

2d16803c56 crypto: blake2s - remove shash module
BLAKE2s has no currently known use as an shash. Just remove all of this
unnecessary plumbing. Removing this shash was something we talked about
back when we were making BLAKE2s a built-in, but I simply never got
around to doing it. So this completes that project.

Importantly, this fixs a bug in which the lib code depends on
crypto_simd_disabled_for_test, causing linker errors.

Also add more alignment tests to the selftests and compare SIMD and
non-SIMD compression functions, to make up for what we lose from
testmgr.c.

7ff554ced7 crypto: hctr2 - Add HCTR2 support
Add support for HCTR2 as a template.  HCTR2 is a length-preserving
encryption mode that is efficient on processors with instructions to
accelerate AES and carryless multiplication, e.g. x86 processors with
AES-NI and CLMUL, and ARM processors with the ARMv8 Crypto Extensions.

As a length-preserving encryption mode, HCTR2 is suitable for
applications such as storage encryption where ciphertext expansion is
not possible, and thus authenticated encryption cannot be used.
Currently, such applications usually use XTS, or in some cases Adiantum.
XTS has the disadvantage that it is a narrow-block mode: a bitflip will
only change 16 bytes in the resulting ciphertext or plaintext.  This
reveals more information to an attacker than necessary.

HCTR2 is a wide-block mode, so it provides a stronger security property:
a bitflip will change the entire message.  HCTR2 is somewhat similar to
Adiantum, which is also a wide-block mode.  However, HCTR2 is designed
to take advantage of existing crypto instructions, while Adiantum
targets devices without such hardware support.  Adiantum is also
designed with longer messages in mind, while HCTR2 is designed to be
efficient even on short messages.

HCTR2 requires POLYVAL and XCTR as components.  More information on
HCTR2 can be found here: "Length-preserving encryption with HCTR2":

f3c923a09c crypto: polyval - Add POLYVAL support
Add support for POLYVAL, an ε-Δ-universal hash function similar to
GHASH.  This patch only uses POLYVAL as a component to implement HCTR2
mode.  It should be noted that POLYVAL was originally specified for use
in AES-GCM-SIV (RFC 8452), but the kernel does not currently support
this mode.

POLYVAL is implemented as an shash algorithm.  The implementation is
modified from ghash-generic.c.

17fee07a2a crypto: xctr - Add XCTR support
Add a generic implementation of XCTR mode as a template.  XCTR is a
blockcipher mode similar to CTR mode.  XCTR uses XORs and little-endian
addition rather than big-endian arithmetic which has two advantages:  It
is slightly faster on little-endian CPUs and it is less likely to be
implemented incorrect since integer overflows are not possible on
practical input sizes.  XCTR is used as a component to implement HCTR2.

More information on XCTR mode can be found in the HCTR2 paper:

Note that the dh-generic implementation would have initialized its
struct dh_ctx's ->q from the decoded struct dh's ->q, if present. If this
struct dh_ctx's ->q would ever have been non-NULL, it would have enabled a
full key validation as specified in NIST SP800-56A in dh_is_pubkey_valid().
However, as outlined above, ->q is always NULL in practice and the full key
validation code is effectively dead. A later patch will make
dh_is_pubkey_valid() to calculate Q from P on the fly, if possible, so
don't remove struct dh_ctx's ->q now, but leave it there until that has
happened.

1. crypto and crypto/atmel-ecc:
   Move curve id of ECDH from the key into the algorithm name instead
   in crypto and atmel-ecc, so ECDH algorithm name change form 'ecdh'
   to 'ecdh-nist-pxxx', and we cannot use 'curve_id' in 'struct ecdh';
2. crypto/testmgr and net/bluetooth:
   Modify 'testmgr.c', 'testmgr.h' and 'net/bluetooth' to adapt
   the modification.

784506a1df crypto: serpent - get rid of obsolete tnepres variant
It is not trivial to trace back why exactly the tnepres variant of
serpent was added ~17 years ago - Google searches come up mostly empty,
but it seems to be related with the 'kerneli' version, which was based
on an incorrect interpretation of the serpent spec.

In other words, nobody is likely to care anymore today, so let's get rid
of it.

49763fc6b1 crypto: testmgr - generate inauthentic AEAD test vectors
The whole point of using an AEAD over length-preserving encryption is
that the data is authenticated.  However currently the fuzz tests don't
test any inauthentic inputs to verify that the data is actually being
authenticated.  And only two algorithms ("rfc4543(gcm(aes))" and
"ccm(aes)") even have any inauthentic test vectors at all.

Therefore, update the AEAD fuzz tests to sometimes generate inauthentic
test vectors, either by generating a (ciphertext, AAD) pair without
using the key, or by mutating an authentic pair that was generated.

To avoid flakiness, only assume this works reliably if the auth tag is
at least 8 bytes.  Also account for the rfc4106, rfc4309, and rfc7539esp
algorithms intentionally ignoring the last 8 AAD bytes, and for some
algorithms doing extra checks that result in EINVAL rather than EBADMSG.

a1afe27492 crypto: testmgr - add test vectors for blake2b
Test vectors for blake2b with various digest sizes. As the algorithm is
the same up to the digest calculation, the key and input data length is
distributed in a way that tests all combinanions of the two over the
digest sizes.

Based on the suggestion from Eric, the following input sizes are tested
[0, 1, 7, 15, 64, 247, 256], where blake2b blocksize is 128, so the
padded and the non-padded input buffers are tested.

          blake2b-160  blake2b-256  blake2b-384  blake2b-512
         ---------------------------------------------------
len=0   | klen=0       klen=1       klen=32      klen=64
len=1   | klen=32      klen=64      klen=0       klen=1
len=7   | klen=64      klen=0       klen=1       klen=32
len=15  | klen=1       klen=32      klen=64      klen=0
len=64  | klen=0       klen=1       klen=32      klen=64
len=247 | klen=32      klen=64      klen=0       klen=1
len=256 | klen=64      klen=0       klen=1       klen=32

Where key:

- klen=0: empty key
- klen=1: 1 byte value 0x42, 'B'
- klen=32: first 32 bytes of the default key, sequence 00..1f
- klen=64: default key, sequence 00..3f

The unkeyed vectors are ordered before keyed, as this is required by
testmgr.
