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: x86/nh: Migrate optimized code into library
Migrate the x86_64 implementations of NH into lib/crypto/. This makes the nh() function be optimized on x86_64 kernels.
Note: this temporarily makes the adiantum template not utilize the x86_64 optimized NH code. This is resolved in a later commit that converts the adiantum template to use nh() instead of "nhpoly1305".
