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. * tag 'libcrypto-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux: (53 commits) lib/crypto: mldsa: Clarify the documentation for mldsa_verify() slightly lib/crypto: aes: Drop 'volatile' from aes_sbox and aes_inv_sbox lib/crypto: aes: Remove old AES en/decryption functions lib/crypto: aesgcm: Use new AES library API lib/crypto: aescfb: Use new AES library API crypto: omap - Use new AES library API crypto: inside-secure - Use new AES library API crypto: drbg - Use new AES library API crypto: crypto4xx - Use new AES library API crypto: chelsio - Use new AES library API crypto: ccp - Use new AES library API crypto: x86/aes-gcm - Use new AES library API crypto: arm64/ghash - Use new AES library API crypto: arm/ghash - Use new AES library API staging: rtl8723bs: core: Use new AES library API net: phy: mscc: macsec: Use new AES library API chelsio: Use new AES library API Bluetooth: SMP: Use new AES library API crypto: x86/aes - Remove the superseded AES-NI crypto_cipher lib/crypto: x86/aes: Add AES-NI optimization ...

- * These big endian AES encryption/decryption tables have been taken from

- * of rlwimi/lwz instructions with a minimum of table registers (usually only
- * one required). Thus they are aligned to 4K. The locality of rotated values

- * instructions. E.g. evldw, evlwwsplat, ...
- *
- * For the safety-conscious it has to be noted that they might be vulnerable
- * to cache timing attacks because of their size. Nevertheless in contrast to
- * the generic tables they have been reduced from 16KB to 8KB + 256 bytes.
- * This is a quite good tradeoff for low power devices (e.g. routers) without
- * dedicated encryption hardware where we usually have no multiuser
- * environment.

-# ====================================================================
-#
-# This module implements support for AES instructions as per PowerISA
-# specification version 2.07, first implemented by POWER8 processor.
-# The module is endian-agnostic in sense that it supports both big-
-# and little-endian cases. Data alignment in parallelizable modes is
-# handled with VSX loads and stores, which implies MSR.VSX flag being
-# set. It should also be noted that ISA specification doesn't prohibit
-# alignment exceptions for these instructions on page boundaries.

-####################### WARNING: Here be dragons! #######################
-#
-# This code is written as 'ctr32', based on a 32-bit counter used
-# upstream. The kernel does *not* use a 32-bit counter. The kernel uses
-# a 128-bit counter.
-#
-# This leads to subtle changes from the upstream code: the counter
-# is incremented with vaddu_q_m rather than vaddu_w_m. This occurs in
-# both the bulk (8 blocks at a time) path, and in the individual block
-# path. Be aware of this when doing updates.
-#
-# See:
-# 1d4aa0b4c181 ("crypto: vmx - Fixing AES-CTR counter bug")
-# 009b30ac7444 ("crypto: vmx - CTR: always increment IV as quadword")
