2022-04-08crypto: sm3,sm4 - move into crypto directoryJason A. Donenfeld1-6/+12
The lib/crypto libraries live in lib because they are used by various drivers of the kernel. In contrast, the various helper functions in crypto are there because they're used exclusively by the crypto API. The SM3 and SM4 helper functions were erroniously moved into lib/crypto/ instead of crypto/, even though there are no in-kernel users outside of the crypto API of those functions. This commit moves them into crypto/. Cc: Herbert Xu <herbert@gondor.apana.org.au> Cc: Tianjia Zhang <tianjia.zhang@linux.alibaba.com> Cc: Eric Biggers <ebiggers@kernel.org> Signed-off-by: Jason A.

Hardware specific features may be able to calculate a crc64, so provide a framework for drivers to register their implementation. If nothing is registered, fallback to the generic table lookup implementation. The implementation is modeled after the crct10dif equivalent.

2022-03-03crypto: dh - implement private key generation primitive for ffdheXYZ(dh)Nicolai Stange1-0/+1
The support for NVME in-band authentication currently in the works ([1]) needs to generate ephemeral DH keys for use with the RFC 7919 safe-prime FFDHE groups. In analogy to ECDH and its ecc_gen_privkey(), implement a dh_safe_prime_gen_privkey() and invoke it from the ffdheXYZ(dh) templates' common ->set_secret(), i.e. dh_safe_prime_set_secret(), in case the input ->key_size is zero. As the RFC 7919 FFDHE groups are classified as approved safe-prime groups by SP800-56Arev3, it's worthwhile to make the new dh_safe_prime_gen_privkey() to follow the approach specified in SP800-56Arev3, sec. 5.6.1.1.3 ("Key-Pair Generation Using Extra Random Bits") in order to achieve conformance. SP800-56Arev3 specifies a lower as well as an upper bound on the generated key's length: - it must be >= two times the maximum supported security strength of the group in question and - it must be <= the length of the domain parameter Q. For any safe-prime group Q = (P - 1)/2 by definition and the individual maximum supported security strengths as specified by SP800-56Arev3 have been made available as part of the FFDHE dh_safe_prime definitions introduced with a previous patch. Make dh_safe_prime_gen_privkey() pick twice the maximum supported strength rounded up to the next power of two for the output key size. This choice respects both, the lower and upper bounds given by SP800-90Arev3 for any of the approved safe-prime groups and is also in line with the NVME base spec 2.0, which requires the key size to be >= 256bits.

2022-03-03crypto: dh - implement ffdheXYZ(dh) templatesNicolai Stange1-0/+6
Current work on NVME in-band authentication support ([1]) needs to invoke DH with the FFDHE safe-prime group parameters specified in RFC 7919. Introduce a new CRYPTO_DH_RFC7919_GROUPS Kconfig option. If enabled, make dh_generic register a couple of ffdheXYZ(dh) templates, one for each group: ffdhe2048(dh), ffdhe3072(dh), ffdhe4096(dh), ffdhe6144(dh) and ffdhe8192(dh). Their respective ->set_secret() expects a (serialized) struct dh, just like the underlying "dh" implementation does, but with the P and G values unset so that the safe-prime constants for the given group can be filled in by the wrapping template. Internally, a struct dh_safe_prime instance is being defined for each of the ffdheXYZ(dh) templates as appropriate. In order to prepare for future key generation, fill in the maximum security strength values as specified by SP800-56Arev3 on the go, even though they're not needed at this point yet. Implement the respective ffdheXYZ(dh) crypto_template's ->create() by simply forwarding any calls to the __dh_safe_prime_create() helper introduced with the previous commit, passing the associated dh_safe_prime in addition to the received ->create() arguments.

2022-01-07lib/crypto: blake2s: include as built-inJason A. Donenfeld1-1/+2
In preparation for using blake2s in the RNG, we change the way that it is wired-in to the build system. Instead of using ifdefs to select the right symbol, we use weak symbols. And because ARM doesn't need the generic implementation, we make the generic one default only if an arch library doesn't need it already, and then have arch libraries that do need it opt-in. So that the arch libraries can remain tristate rather than bool, we then split the shash part from the glue code.

2021-11-26crypto: kdf - add SP800-108 counter key derivation functionStephan Müller1-0/+4
SP800-108 defines three KDFs - this patch provides the counter KDF implementation. The KDF is implemented as a service function where the caller has to maintain the hash / HMAC state. Apart from this hash/HMAC state, no additional state is required to be maintained by either the caller or the KDF implementation. The key for the KDF is set with the crypto_kdf108_setkey function which is intended to be invoked before the caller requests a key derivation operation via crypto_kdf108_ctr_generate. SP800-108 allows the use of either a HMAC or a hash as crypto primitive for the KDF. When a HMAC primtive is intended to be used, crypto_kdf108_setkey must be used to set the HMAC key. Otherwise, for a hash crypto primitve crypto_kdf108_ctr_generate can be used immediately after allocating the hash handle.

Like the implementation of AESNI/AVX, this patch adds an accelerated implementation of AESNI/AVX2. In terms of code implementation, by reusing AESNI/AVX mode-related codes, the amount of code is greatly reduced. From the benchmark data, it can be seen that when the block size is 1024, compared to AVX acceleration, the performance achieved by AVX2 has increased by about 70%, it is also 7.7 times of the pure software implementation of sm4-generic. The main algorithm implementation comes from SM4 AES-NI work by libgcrypt and Markku-Juhani O. Saarinen at: https://github.com/mjosaarinen/sm4ni This optimization supports the four modes of SM4, ECB, CBC, CFB, and CTR. Since CBC and CFB do not support multiple block parallel encryption, the optimization effect is not obvious. Benchmark on Intel i5-6200U 2.30GHz, performance data of three implementation methods, pure software sm4-generic, aesni/avx acceleration, and aesni/avx2 acceleration, the data comes from the 218 mode and 518 mode of tcrypt.

2021-01-08crypto: x86/aes-ni-xts - rewrite and drop indirections via glue helperArd Biesheuvel1-1/+0
The AES-NI driver implements XTS via the glue helper, which consumes a struct with sets of function pointers which are invoked on chunks of input data of the appropriate size, as annotated in the struct. Let's get rid of this indirection, so that we can perform direct calls to the assembler helpers. Instead, let's adopt the arm64 strategy, i.e., provide a helper which can consume inputs of any size, provided that the penultimate, full block is passed via the last call if ciphertext stealing needs to be applied. This also allows us to enable the XTS mode for i386.

2020-11-27crypto: tcrypt - permit tcrypt.ko to be builtinArd Biesheuvel1-1/+1
When working on crypto algorithms, being able to run tcrypt quickly without booting an entire Linux installation can be very useful. For instance, QEMU/kvm can be used to boot a kernel from the command line, and having tcrypt.ko builtin would allow tcrypt to be executed to run benchmarks, or to run tests for algorithms that need to be instantiated from templates, without the need to make it past the point where the rootfs is mounted. So let's relax the requirement that tcrypt can only be built as a module when CONFIG_EXPERT is enabled.
