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: sparc: Drop optimized MD5 code
MD5 is obsolete. Continuing to maintain architecture-optimized implementations of MD5 is unnecessary and risky. It diverts resources from the modern algorithms that are actually important.
While there was demand for continuing to maintain the PowerPC optimized MD5 code to accommodate userspace programs that are misusing AF_ALG (https://lore.kernel.org/linux-crypto/c4191597-341d-4fd7-bc3d-13daf7666c41@csgroup.eu/), no such demand has been seen for the SPARC optimized MD5 code.
Thus, let's drop it and focus effort on the more modern SHA algorithms, which already have optimized code for SPARC.

lib: Move crypto library tests to Runtime Testing menu
Currently the kconfig options for the crypto library KUnit tests appear in the menu:
-> Library routines -> Crypto library routines
However, this is the only content of "Crypto library routines". I.e., it is empty when CONFIG_KUNIT=n. This is because the crypto library routines themselves don't have (or need to have) prompts.
Since this usually ends up as an unnecessary empty menu, let's remove this menu and instead source the lib/crypto/tests/Kconfig file from lib/Kconfig.debug inside the "Runtime Testing" menu:
-> Kernel hacking -> Kernel Testing and Coverage -> Runtime Testing
This puts the prompts alongside the ones for most of the other lib/ KUnit tests. This seems to be a much better match to how the kconfig menus are organized.

lib/crypto: sm3: Add SM3 library API
Add a straightforward library API for SM3, mirroring the ones for the other hash algorithms. It uses the existing generic implementation of SM3's compression function in lib/crypto/sm3.c. Hooks are added for architecture-optimized implementations, which later commits will wire up to the existing optimized SM3 code for arm64, riscv, and x86.
Note that the rationale for this is *not* that SM3 should be used, or that any kernel subsystem currently seems like a candidate for switching from the sm3 crypto_shash to SM3 library. (SM3, in fact, shouldn't be used. Likewise you shouldn't use MD5, SHA-1, RC4, etc...)
Rather, it's just that this will simplify how the kernel's existing SM3 code is integrated and make it much easier to maintain and test. SM3 is one of the only hash algorithms with arch-optimized code that is still integrated in the old way. By converting it to the new lib/crypto/ code organization, 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 much point 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 'struct sm3_state' and the sm3_block_generic() function which uses it are temporarily kept around until their users are updated by later commits.

This makes the GHASH library be optimized with the RISC-V Vector Cryptography Extension. It also greatly reduces the amount of riscv-specific glue code that is needed, and it fixes the issue where this optimized GHASH code was disabled by default.
Note that this RISC-V code has multiple opportunities for improvement, such as adding more parallelism, providing an optimized multiplication function, and directly supporting POLYVAL. But for now, this commit simply tweaks ghash_zvkg() slightly to make it compatible with the library, then wires it up to ghash_blocks_arch().
ghash_preparekey_arch() is also implemented to store the copy of the raw key needed by the vghsh.vv instruction.

lib/crypto: powerpc/ghash: Migrate optimized code into library
Remove the "p8_ghash" crypto_shash algorithm. Move the corresponding assembly code into lib/crypto/, and wire it up to the GHASH library.
This makes the GHASH library be optimized for POWER8. It also greatly reduces the amount of powerpc-specific glue code that is needed, and it fixes the issue where this optimized GHASH code was disabled by default.
Note that previously the C code defined the POWER8 GHASH key format as "u128 htable[16]", despite the assembly code only using four entries. Fix the C code to use the correct key format. To fulfill the library API contract, also make the key preparation work in all contexts.
Note that the POWER8 assembly code takes the accumulator in GHASH format, but it actually byte-reflects it to get it into POLYVAL format. The library already works with POLYVAL natively. For now, just wire up this existing code by converting it to/from GHASH format in C code. This should be cleaned up to eliminate the unnecessary conversion later.

Remove the "ghash-neon" crypto_shash algorithm. Move the corresponding assembly code into lib/crypto/, and wire it up to the GHASH library.
This makes the GHASH library be optimized on arm (though only with NEON, not PMULL; for now the goal is just parity with crypto_shash). It greatly reduces the amount of arm-specific glue code that is needed, and it fixes the issue where this optimization was disabled by default.
To integrate the assembly code correctly with the library, make the following tweaks:
- Change the type of 'blocks' from int to size_t. - Change the types of 'dg' and 'h' to polyval_elem. Note that this simply reflects the format that the code was already using, at least on little endian CPUs. For big endian CPUs, add byte-swaps. - Remove the 'head' argument, which is no longer needed.

lib/crypto: gf128hash: Rename polyval module to gf128hash
Currently, the standalone GHASH code is coupled with crypto_shash. This has resulted in unnecessary complexity and overhead, as well as the code being unavailable to library code such as the AES-GCM library. Like was done with POLYVAL, it needs to find a new home in lib/crypto/.
GHASH and POLYVAL are closely related and can each be implemented in terms of each other. Optimized code for one can be reused with the other. But also since GHASH tends to be difficult to implement directly due to its unnatural bit order, most modern GHASH implementations (including the existing arm, arm64, powerpc, and x86 optimized GHASH code, and the new generic GHASH code I'll be adding) actually reinterpret the GHASH computation as an equivalent POLYVAL computation, pre and post-processing the inputs and outputs to map to/from POLYVAL.
Given this close relationship, it makes sense to group the GHASH and POLYVAL code together in the same module. This gives us a wide range of options for implementing them, reusing code between the two and properly utilizing whatever instructions each architecture provides.
Thus, GHASH support will be added to the library module that is currently called "polyval". Rename it to an appropriate name: "gf128hash". Rename files, options, functions, etc. where appropriate to reflect the upcoming sharing with GHASH. (Note: polyval_kunit is not renamed, as ghash_kunit will be added alongside it instead.)

lib/crypto: aes: Add support for CBC-based MACs
Add support for CBC-based MACs to the AES library, specifically AES-CMAC, AES-XCBC-MAC, and AES-CBC-MAC.
Of these three algorithms, AES-CMAC is the most modern and the most commonly used. Use cases for the AES-CMAC library include the kernel's SMB client and server, and the bluetooth and mac80211 drivers.
Support for AES-XCBC-MAC and AES-CBC-MAC is included so that there will be no performance regression in the "xcbc(aes)" and "ccm(aes)" support in the traditional crypto API once the arm64-optimized code is migrated into the library. AES-XCBC-MAC is given its own key preparation function but is otherwise identical to AES-CMAC and just reuses the AES-CMAC structs and functions.
The implementation automatically uses the optimized AES key expansion and single block en/decryption functions. It also allows architectures to provide an optimized implementation of aes_cbcmac_blocks(), which allows the existing arm64-optimized code for these modes to be used.
Just put the code for these modes directly in the libaes module rather than in a separate module. This is simpler, it makes it easier to share code between AES modes, and it increases the amount of inlining that is possible. (Indeed, for these reasons, most of the architecture-optimized AES code already provides multiple modes per module. x86 for example has only a single aesni-intel module. So to a large extent, this design choice just reflects the status quo.)
However, since there are a lot of AES modes, there's still some value in omitting modes that are not needed at all in a given kernel. Therefore, make these modes an optional feature of libaes, controlled by CONFIG_CRYPTO_LIB_AES_CBC_MACS. This seems like a good middle ground.

Merge tag 'libcrypto-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux
Pull crypto library updates from Eric Biggers:
- Add support for verifying ML-DSA signatures.
ML-DSA (Module-Lattice-Based Digital Signature Algorithm) is a recently-standardized post-quantum (quantum-resistant) signature algorithm. It was known as Dilithium pre-standardization.
The first use case in the kernel will be module signing. But there are also other users of RSA and ECDSA signatures in the kernel that might want to upgrade to ML-DSA eventually.
- Improve the AES library:
- Make the AES key expansion and single block encryption and decryption functions use the architecture-optimized AES code. Enable these optimizations by default.
- Support preparing an AES key for encryption-only, using about half as much memory as a bidirectional key.
- Replace the existing two generic implementations of AES with a single one.
- Simplify how Adiantum message hashing is implemented. Remove the "nhpoly1305" crypto_shash in favor of direct lib/crypto/ support for NH hashing, and enable optimizations by default.
