2024-04-05powerpc/crypto/chacha-p10: Fix failure on non Power10Michael Ellerman1-1/+7
The chacha-p10-crypto module provides optimised chacha routines for Power10. It also selects CRYPTO_ARCH_HAVE_LIB_CHACHA which says it provides chacha_crypt_arch() to generic code. Notably the module needs to provide chacha_crypt_arch() regardless of whether it is loaded on Power10 or an older CPU. The implementation of chacha_crypt_arch() already has a fallback to chacha_crypt_generic(), however the module as a whole fails to load on pre-Power10, because of the use of module_cpu_feature_match(). This breaks for example loading wireguard: jostaberry-1:~ # modprobe -v wireguard insmod /lib/modules/6.8.0-lp155.8.g7e0e887-default/kernel/arch/powerpc/crypto/chacha-p10-crypto.ko.zst modprobe: ERROR: could not insert 'wireguard': No such device Fix it by removing module_cpu_feature_match(), and instead check the CPU feature manually. If the CPU feature is not found, the module still loads successfully, but doesn't register the Power10 specific algorithms. That allows chacha_crypt_generic() to remain available for use, fixing the problem.

In particular the newly added files produce functions with identical names to the existing code. When the kernel is built with CONFIG_CRYPTO_AES_GCM_P10=y and CONFIG_CRYPTO_DEV_VMX_ENCRYPT=y that leads to link errors, eg: ld: drivers/crypto/vmx/aesp8-ppc.o: in function `aes_p8_set_encrypt_key': (.text+0xa0): multiple definition of `aes_p8_set_encrypt_key'; arch/powerpc/crypto/aesp8-ppc.o:(.text+0xa0): first defined here ... ld: drivers/crypto/vmx/ghashp8-ppc.o: in function `gcm_ghash_p8': (.text+0x140): multiple definition of `gcm_ghash_p8'; arch/powerpc/crypto/ghashp8-ppc.o:(.text+0x2e4): first defined here Fix it for now by renaming the newly added files and functions to use "p10" instead of "p8" in the names.

The prandom_bytes() function has been a deprecated inline wrapper around get_random_bytes() for several releases now, and compiles down to the exact same code. Replace the deprecated wrapper with a direct call to the real function. This was done as a basic find and replace.

2020-11-20crypto: sha - split sha.h into sha1.h and sha2.hEric Biggers3-3/+3
Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2, and <crypto/sha3.h> contains declarations for SHA-3. This organization is inconsistent, but more importantly SHA-1 is no longer considered to be cryptographically secure. So to the extent possible, SHA-1 shouldn't be grouped together with any of the other SHA versions, and usage of it should be phased out. Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and <crypto/sha2.h>, and make everyone explicitly specify whether they want the declarations for SHA-1, SHA-2, or both. This avoids making the SHA-1 declarations visible to files that don't want anything to do with SHA-1. It also prepares for potentially moving sha1.h into a new insecure/ or dangerous/ directory.
