crypto: aria - Implement ARIA symmetric cipher algorithm

2022-07-15T08:38:19+00:00

ARIA(RFC 5794) is a symmetric block cipher algorithm.
This algorithm is being used widely in South Korea as a standard cipher
algorithm.
This code is written based on the ARIA implementation of OpenSSL.
The OpenSSL code is based on the distributed source code[1] by KISA.

ARIA has three key sizes and corresponding rounds.
ARIA128: 12 rounds.
ARIA192: 14 rounds.
ARIA245: 16 rounds.

crypto: blake2s - remove shash module

2022-06-10T08:43:49+00:00

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.

crypto: x86/polyval - Add PCLMULQDQ accelerated implementation of POLYVAL

2022-06-10T08:40:17+00:00

Add hardware accelerated version of POLYVAL for x86-64 CPUs with
PCLMULQDQ support.

This implementation is accelerated using PCLMULQDQ instructions to
perform the finite field computations.  For added efficiency, 8 blocks
of the message are processed simultaneously by precomputing the first
8 powers of the key.

Schoolbook multiplication is used instead of Karatsuba multiplication
because it was found to be slightly faster on x86-64 machines.
Montgomery reduction must be used instead of Barrett reduction due to
the difference in modulus between POLYVAL's field and other finite
fields.

More information on POLYVAL can be found in the HCTR2 paper:

crypto: polyval - Add POLYVAL support

2022-06-10T08:40:17+00:00

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.

crypto: sm4 - export sm4 constant arrays

2022-04-08T08:12:46+00:00

Export the constant arrays fk, ck, sbox of the SM4 algorithm, and
add the 'crypto_sm4_' prefix, where sbox is used in the SM4 NEON
implementation for the tbl/tbx instruction to replace the S-BOX,
and the fk, ck arrays are used in the SM4 CE implementation. Use
the sm4ekey instruction to speed up key expansion operations.

KEYS: remove support for asym_tpm keys

2022-03-08T11:55:52+00:00

asym_tpm keys are tied to TPM v1.2, which uses outdated crypto and has
been deprecated in favor of TPM v2.0 for over 7 years.  A very quick
look at this code also immediately found some memory safety bugs
(https://lore.kernel.org/r/20220113235440.90439-2-ebiggers@kernel.org).
Note that this code is reachable by unprivileged users.

According to Jarkko (one of the keyrings subsystem maintainers), this
code has no practical use cases, and he isn't willing to maintain it
(https://lore.kernel.org/r/YfFZPbKkgYJGWu1Q@iki.fi).

Therefore, let's remove it.

Note that this feature didn't have any documentation or tests, so we
don't need to worry about removing those.
