Linus Torvalds 370c388319 Crypto library updates for 7.1
- 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
 
 Note: the overall diffstat is neutral, but when the test code is
 excluded it is significantly negative:
