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)"
