This series adds BLAKE2b support to lib/crypto/ and reimplements the
blake2b-* crypto_shash algorithms on top of it.
To prepare for that, patches 1-4 clean up the BLAKE2s library code a
bit, and patch 5 adds some missing 64-bit byteorder helper functions.
Patches 6-8 add the BLAKE2b library API (closely mirroring the BLAKE2s
one), and patch 9 makes crypto_shash use it. As usual, the library APIs
are documented (with kerneldoc) and tested (with KUnit).
With that done, all of btrfs's checksum algorithms have library APIs.
So patch 10 converts btrfs to use the library APIs instead of shash.
This has quite a few benefits, as detailed in that patch.
Patches 1-9 are targeting libcrypto-next for 6.19. Patch 10 can go
through the btrfs tree later.
Eric Biggers (10):
lib/crypto: blake2s: Adjust parameter order of blake2s()
lib/crypto: blake2s: Rename blake2s_state to blake2s_ctx
lib/crypto: blake2s: Drop excessive const & rename block => data
lib/crypto: blake2s: Document the BLAKE2s library API
byteorder: Add le64_to_cpu_array() and cpu_to_le64_array()
lib/crypto: blake2b: Add BLAKE2b library functions
lib/crypto: arm/blake2b: Migrate optimized code into library
lib/crypto: tests: Add KUnit tests for BLAKE2b
crypto: blake2b - Reimplement using library API
btrfs: switch to library APIs for checksums
