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

Merge tag 'libcrypto-updates-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux
Pull crypto library updates from Eric Biggers: "This is the main crypto library pull request for 6.17. The main focus this cycle is on reorganizing the SHA-1 and SHA-2 code, providing high-quality library APIs for SHA-1 and SHA-2 including HMAC support, and establishing conventions for lib/crypto/ going forward:
- Migrate the SHA-1 and SHA-512 code (and also SHA-384 which shares most of the SHA-512 code) into lib/crypto/. This includes both the generic and architecture-optimized code. Greatly simplify how the architecture-optimized code is integrated. Add an easy-to-use library API for each SHA variant, including HMAC support. Finally, reimplement the crypto_shash support on top of the library API.
- Apply the same reorganization to the SHA-256 code (and also SHA-224 which shares most of the SHA-256 code). This is a somewhat smaller change, due to my earlier work on SHA-256. But this brings in all the same additional improvements that I made for SHA-1 and SHA-512.
There are also some smaller changes:
- Move the architecture-optimized ChaCha, Poly1305, and BLAKE2s code from arch/$(SRCARCH)/lib/crypto/ to lib/crypto/$(SRCARCH)/. For these algorithms it's just a move, not a full reorganization yet.
- Fix the MIPS chacha-core.S to build with the clang assembler.
- Fix the Poly1305 functions to work in all contexts.
- Fix a performance regression in the x86_64 Poly1305 code.
- Clean up the x86_64 SHA-NI optimized SHA-1 assembly code.
Note that since the new organization of the SHA code is much simpler, the diffstat of this pull request is negative, despite the addition of new fully-documented library APIs for multiple SHA and HMAC-SHA variants.
These APIs will allow further simplifications across the kernel as users start using them instead of the old-school crypto API. (I've already written a lot of such conversion patches, removing over 1000 more lines of code. But most of those will target 6.18 or later)"

lib/crypto: arm64: Move arch/arm64/lib/crypto/ into lib/crypto/
Move the contents of arch/arm64/lib/crypto/ into lib/crypto/arm64/.
The new code organization makes a lot more sense for how this code actually works and is developed. In particular, it makes it possible to build each algorithm as a single module, with better inlining and dead code elimination. For a more detailed explanation, see the patchset which did this for the CRC library code: https://lore.kernel.org/r/20250607200454.73587-1-ebiggers@kernel.org/. Also see the patchset which did this for SHA-512: https://lore.kernel.org/linux-crypto/20250616014019.415791-1-ebiggers@kernel.org/
This is just a preparatory commit, which does the move to get the files into their new location but keeps them building the same way as before. Later commits will make the actual improvements to the way the arch-optimized code is integrated for each algorithm.
Add a gitignore entry for the removed directory arch/arm64/lib/crypto/ so that people don't accidentally commit leftover generated files.
