Hardware specific features may be able to calculate a crc64, so provide
a framework for drivers to register their implementation. If nothing is
registered, fallback to the generic table lookup implementation. The
implementation is modeled after the crct10dif equivalent.

Nicolai Stange 1e20796456 crypto: dh - implement private key generation primitive for ffdheXYZ(dh)
The support for NVME in-band authentication currently in the works ([1])
needs to generate ephemeral DH keys for use with the RFC 7919 safe-prime
FFDHE groups.

In analogy to ECDH and its ecc_gen_privkey(), implement a
dh_safe_prime_gen_privkey() and invoke it from the ffdheXYZ(dh) templates'
common ->set_secret(), i.e. dh_safe_prime_set_secret(), in case the input
->key_size is zero.

As the RFC 7919 FFDHE groups are classified as approved safe-prime groups
by SP800-56Arev3, it's worthwhile to make the new
dh_safe_prime_gen_privkey() to follow the approach specified in
SP800-56Arev3, sec. 5.6.1.1.3 ("Key-Pair Generation Using Extra Random
Bits") in order to achieve conformance.

SP800-56Arev3 specifies a lower as well as an upper bound on the generated
key's length:
- it must be >= two times the maximum supported security strength of
  the group in question and
- it must be <= the length of the domain parameter Q.

For any safe-prime group Q = (P - 1)/2 by definition and the individual
maximum supported security strengths as specified by SP800-56Arev3 have
been made available as part of the FFDHE dh_safe_prime definitions
introduced with a previous patch. Make dh_safe_prime_gen_privkey() pick
twice the maximum supported strength rounded up to the next power of two
for the output key size. This choice respects both, the lower and upper
bounds given by SP800-90Arev3 for any of the approved safe-prime groups and
is also in line with the NVME base spec 2.0, which requires the key size to
be >= 256bits.

Nicolai Stange 7dce598197 crypto: dh - implement ffdheXYZ(dh) templates
Current work on NVME in-band authentication support ([1]) needs to invoke
DH with the FFDHE safe-prime group parameters specified in RFC 7919.

Introduce a new CRYPTO_DH_RFC7919_GROUPS Kconfig option. If enabled, make
dh_generic register a couple of ffdheXYZ(dh) templates, one for each group:
ffdhe2048(dh), ffdhe3072(dh), ffdhe4096(dh), ffdhe6144(dh) and
ffdhe8192(dh). Their respective ->set_secret() expects a (serialized)
struct dh, just like the underlying "dh" implementation does, but with the
P and G values unset so that the safe-prime constants for the given group
can be filled in by the wrapping template.

Internally, a struct dh_safe_prime instance is being defined for each of
the ffdheXYZ(dh) templates as appropriate. In order to prepare for future
key generation, fill in the maximum security strength values as specified
by SP800-56Arev3 on the go, even though they're not needed at this point
yet.

Implement the respective ffdheXYZ(dh) crypto_template's ->create() by
simply forwarding any calls to the __dh_safe_prime_create() helper
introduced with the previous commit, passing the associated dh_safe_prime
in addition to the received ->create() arguments.

Jason A. Donenfeld 6048fdcc5f lib/crypto: blake2s: include as built-in
In preparation for using blake2s in the RNG, we change the way that it
is wired-in to the build system. Instead of using ifdefs to select the
right symbol, we use weak symbols. And because ARM doesn't need the
generic implementation, we make the generic one default only if an arch
library doesn't need it already, and then have arch libraries that do
need it opt-in. So that the arch libraries can remain tristate rather
than bool, we then split the shash part from the glue code.

Stephan Müller 026a733e66 crypto: kdf - add SP800-108 counter key derivation function
SP800-108 defines three KDFs - this patch provides the counter KDF
implementation.

The KDF is implemented as a service function where the caller has to
maintain the hash / HMAC state. Apart from this hash/HMAC state, no
additional state is required to be maintained by either the caller or
the KDF implementation.

The key for the KDF is set with the crypto_kdf108_setkey function which
is intended to be invoked before the caller requests a key derivation
operation via crypto_kdf108_ctr_generate.

SP800-108 allows the use of either a HMAC or a hash as crypto primitive
for the KDF. When a HMAC primtive is intended to be used,
crypto_kdf108_setkey must be used to set the HMAC key. Otherwise, for a
hash crypto primitve crypto_kdf108_ctr_generate can be used immediately
after allocating the hash handle.

Tianjia Zhang 5b2efa2bb8 crypto: x86/sm4 - add AES-NI/AVX2/x86_64 implementation
Like the implementation of AESNI/AVX, this patch adds an accelerated
implementation of AESNI/AVX2. In terms of code implementation, by
reusing AESNI/AVX mode-related codes, the amount of code is greatly
reduced. From the benchmark data, it can be seen that when the block
size is 1024, compared to AVX acceleration, the performance achieved
by AVX2 has increased by about 70%, it is also 7.7 times of the pure
software implementation of sm4-generic.

The main algorithm implementation comes from SM4 AES-NI work by
libgcrypt and Markku-Juhani O. Saarinen at:
https://github.com/mjosaarinen/sm4ni

This optimization supports the four modes of SM4, ECB, CBC, CFB,
and CTR. Since CBC and CFB do not support multiple block parallel
encryption, the optimization effect is not obvious.

Take the existing small footprint and mostly time invariant C code
and turn it into a SM4 library that can be used for non-performance
critical, casual use of SM4, and as a fallback for, e.g., SIMD code
that needs a secondary path that can be taken in contexts where the
SIMD unit is off limits.

Secondly, some codes have been optimized, such as unrolling small
times loop, removing unnecessary memory shifts, exporting sbox, fk,
ck arrays, and basic encryption and decryption functions.

The AES-NI driver implements XTS via the glue helper, which consumes
a struct with sets of function pointers which are invoked on chunks
of input data of the appropriate size, as annotated in the struct.

Let's get rid of this indirection, so that we can perform direct calls
to the assembler helpers. Instead, let's adopt the arm64 strategy, i.e.,
provide a helper which can consume inputs of any size, provided that the
penultimate, full block is passed via the last call if ciphertext stealing
needs to be applied.

This also allows us to enable the XTS mode for i386.

When working on crypto algorithms, being able to run tcrypt quickly
without booting an entire Linux installation can be very useful. For
instance, QEMU/kvm can be used to boot a kernel from the command line,
and having tcrypt.ko builtin would allow tcrypt to be executed to run
benchmarks, or to run tests for algorithms that need to be instantiated
from templates, without the need to make it past the point where the
rootfs is mounted.

So let's relax the requirement that tcrypt can only be built as a module
when CONFIG_EXPERT is enabled.
