Merge tag 'libcrypto-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linuxPull 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* tag 'libcrypto-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux: (66 commits) lib/crypto: arm64: Assume a little-endian kernel arm64: fpsimd: Remove obsolete cond_yield macro lib/crypto: arm64/sha3: Remove obsolete chunking logic lib/crypto: arm64/sha512: Remove obsolete chunking logic lib/crypto: arm64/sha256: Remove obsolete chunking logic lib/crypto: arm64/sha1: Remove obsolete chunking logic lib/crypto: arm64/poly1305: Remove obsolete chunking logic lib/crypto: arm64/gf128hash: Remove obsolete chunking logic lib/crypto: arm64/chacha: Remove obsolete chunking logic lib/crypto: arm64/aes: Remove obsolete chunking logic lib/crypto: Include instead of lib/crypto: aesgcm: Don't disable IRQs during AES block encryption lib/crypto: aescfb: Don't disable IRQs during AES block encryption lib/crypto: tests: Migrate ChaCha20Poly1305 self-test to KUnit lib/crypto: sparc: Drop optimized MD5 code lib/crypto: mips: Drop optimized MD5 code lib: Move crypto library tests to Runtime Testing menu crypto: sm3 - Remove 'struct sm3_state' crypto: sm3 - Remove the original "sm3_block_generic()" crypto: sm3 - Remove sm3_base.h ...

Sat, 21 Mar 2026 05:09:34 +0100

crypto: sm3 - Remove the original "sm3_block_generic()"Since the architecture-optimized SM3 code was migrated into lib/crypto/,sm3_block_generic() is no longer called. Remove it. Then, since thisfrees up the name, rename sm3_transform() to sm3_block_generic()(matching the naming convention used in other hash algorithms).Acked-by: Ard Biesheuvel Link: https://lore.kernel.org/r/20260321040935.410034-12-ebiggers@kernel.orgSigned-off-by: Eric Biggers List of files: /linux/lib/crypto/sm3.c

324bb3bb75ac21adbbc7e6ea5cdb0a735fb78a56 - lib/crypto: sm3: Add SM3 library API

Sat, 21 Mar 2026 05:09:27 +0100

lib/crypto: sm3: Add SM3 library APIAdd a straightforward library API for SM3, mirroring the ones for theother hash algorithms. It uses the existing generic implementation ofSM3's compression function in lib/crypto/sm3.c. Hooks are added forarchitecture-optimized implementations, which later commits will wire upto the existing optimized SM3 code for arm64, riscv, and x86.Note that the rationale for this is *not* that SM3 should be used, orthat any kernel subsystem currently seems like a candidate for switchingfrom the sm3 crypto_shash to SM3 library. (SM3, in fact, shouldn't beused. Likewise you shouldn't use MD5, SHA-1, RC4, etc...)Rather, it's just that this will simplify how the kernel's existing SM3code is integrated and make it much easier to maintain and test. SM3 isone of the only hash algorithms with arch-optimized code that is stillintegrated in the old way. By converting it to the new lib/crypto/ codeorganization, we'll only have to keep track of one way of doing things.The library will also get a KUnit test suite (as usual for lib/crypto/),so it will become more easily and comprehensively tested as well.Skip adding functions for HMAC-SM3 for now, though. There's not as muchpoint in adding those right now.Note: similar to the other hash algorithms, the library API uses'struct sm3_ctx', not 'struct sm3_state'. The existing 'structsm3_state' and the sm3_block_generic() function which uses it aretemporarily kept around until their users are updated by later commits.Acked-by: Ard Biesheuvel Link: https://lore.kernel.org/r/20260321040935.410034-5-ebiggers@kernel.orgSigned-off-by: Eric Biggers List of files: /linux/lib/crypto/sm3.c
