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: tests: Add KUnit tests for SM3
Add a KUnit test suite for the SM3 library. It closely mirrors the test suites for the other cryptographic hash functions. The actual test and benchmark logic is already in hash-test-template.h; this just wires it up for SM3 in the usual way.
