Merge tag 'libcrypto-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux

Pull crypto library updates from Eric Biggers:

- Migrate more hash algorithms from the traditional crypto subsystem to
lib/crypto/

Like the algorithms migrated earlier (e.g. SHA-*), this simplifies
the implementations, improves performance, enables further
simplifications in calling code, and solves various other issues:

- AES CBC-based MACs (AES-CMAC, AES-XCBC-MAC, and AES-CBC-MAC)

- Support these algorithms in lib/crypto/ using the AES library
and the existing arm64 assembly code

- Reimplement the traditional crypto API's "cmac(aes)",
"xcbc(aes)", and "cbcmac(aes)" on top of the library

- Convert mac80211 to use the AES-CMAC library. Note: several
other subsystems can use it too and will be converted later

- Drop the broken, nonstandard, and likely unused support for
"xcbc(aes)" with key lengths other than 128 bits

- Enable optimizations by default

- GHASH

- Migrate the standalone GHASH code into lib/crypto/

- Integrate the GHASH code more closely with the very similar
POLYVAL code, and improve the generic GHASH implementation to
resist cache-timing attacks and use much less memory

- Reimplement the AES-GCM library and the "gcm" crypto_aead
template on top of the GHASH library. Remove "ghash" from the
crypto_shash API, as it's no longer needed

- Enable optimizations by default

- SM3

- Migrate the kernel's existing SM3 code into lib/crypto/, and
reimplement the traditional crypto API's "sm3" on top of it

- I don't recommend using SM3, but this cleanup is worthwhile
to organize the code the same way as other algorithms

- Testing improvements:

- Add a KUnit test suite for each of the new library APIs

- Migrate the existing ChaCha20Poly1305 test to KUnit

- Make the KUnit all_tests.config enable all crypto library tests

- Move the test kconfig options to the Runtime Testing menu

- Other updates to arch-optimized crypto code:

- Optimize SHA-256 for Zhaoxin CPUs using the Padlock Hash Engine

- Remove some MD5 implementations that are no longer worth keeping

- Drop big endian and voluntary preemption support from the arm64
code, as those configurations are no longer supported on arm64

- Make jitterentropy and samples/tsm-mr use the crypto library APIs

lib/crypto: riscv/sm3: Migrate optimized code into library

Instead of exposing the riscv-optimized SM3 code via a riscv-specific
crypto_shash algorithm, instead just implement the sm3_blocks() library
function. This is much simpler, it makes the SM3 library functions be
riscv-optimized, and it fixes the longstanding issue where the
riscv-optimized SM3 code was disabled by default. SM3 still remains
available through crypto_shash, but individual architectures no longer
need to handle it.

Tweak the prototype of sm3_transform_zvksh_zvkb() to match what the
library expects, including changing the block count to size_t.
Note that the assembly code already treated it as size_t.

Note: to see the diff from arch/riscv/crypto/sm3-riscv64-glue.c to
lib/crypto/riscv/sm3.h, view this commit with 'git show -M10'.

lib/crypto: riscv/ghash: Migrate optimized code into library

Remove the "ghash-riscv64-zvkg" crypto_shash algorithm. Move the
corresponding assembly code into lib/crypto/, modify it to take the
length in blocks instead of bytes, and wire it up to the GHASH library.

This makes the GHASH library be optimized with the RISC-V Vector
Cryptography Extension. It also greatly reduces the amount of
riscv-specific glue code that is needed, and it fixes the issue where
this optimized GHASH code was disabled by default.

Note that this RISC-V code has multiple opportunities for improvement,
such as adding more parallelism, providing an optimized multiplication
function, and directly supporting POLYVAL. But for now, this commit
simply tweaks ghash_zvkg() slightly to make it compatible with the
library, then wires it up to ghash_blocks_arch().

ghash_preparekey_arch() is also implemented to store the copy of the raw
key needed by the vghsh.vv instruction.

Merge tag 'libcrypto-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux

Pull crypto library updates from Eric Biggers:

- Add support for verifying ML-DSA signatures.

ML-DSA (Module-Lattice-Based Digital Signature Algorithm) is a
recently-standardized post-quantum (quantum-resistant) signature
algorithm. It was known as Dilithium pre-standardization.

The first use case in the kernel will be module signing. But there
are also other users of RSA and ECDSA signatures in the kernel that
might want to upgrade to ML-DSA eventually.

- Improve the AES library:

- Make the AES key expansion and single block encryption and
decryption functions use the architecture-optimized AES code.
Enable these optimizations by default.

- Support preparing an AES key for encryption-only, using about
half as much memory as a bidirectional key.

- Replace the existing two generic implementations of AES with a
single one.

- Simplify how Adiantum message hashing is implemented. Remove the
"nhpoly1305" crypto_shash in favor of direct lib/crypto/ support for
NH hashing, and enable optimizations by default.

lib/crypto: riscv/aes: Migrate optimized code into library

Move the aes_encrypt_zvkned() and aes_decrypt_zvkned() assembly
functions into lib/crypto/, wire them up to the AES library API, and
remove the "aes-riscv64-zvkned" crypto_cipher algorithm.

To make this possible, change the prototypes of these functions to
take (rndkeys, key_len) instead of a pointer to crypto_aes_ctx, and
change the RISC-V AES-XTS code to implement tweak encryption using the
AES library instead of directly calling aes_encrypt_zvkned().

The result is that both the AES library and crypto_cipher APIs use
RISC-V's AES instructions, whereas previously only crypto_cipher did
(and it wasn't enabled by default, which this commit fixes as well).

lib/crypto: riscv: Depend on RISCV_EFFICIENT_VECTOR_UNALIGNED_ACCESS

Replace the RISCV_ISA_V dependency of the RISC-V crypto code with
RISCV_EFFICIENT_VECTOR_UNALIGNED_ACCESS, which implies RISCV_ISA_V as
well as vector unaligned accesses being efficient.

This is necessary because this code assumes that vector unaligned
accesses are supported and are efficient. (It does so to avoid having
to use lots of extra vsetvli instructions to switch the element width
back and forth between 8 and either 32 or 64.)

This was omitted from the code originally just because the RISC-V kernel
support for detecting this feature didn't exist yet. Support has now
been added, but it's fragmented into per-CPU runtime detection, a
command-line parameter, and a kconfig option. The kconfig option is the
only reasonable way to do it, though, so let's just rely on that.
