| * crypto: blake2b - simplify key initDavid Sterba2019-11-221-8/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The keyed init writes the key bytes to the input buffer and does an update. We can do that in two ways: fill the buffer and update immediatelly. This is what current blake2b_init_key does. Any other following _update or _final will continue from the updated state. The other way is to write the key and set the number of bytes to process at the next _update or _final, lazy evaluation. Which leads to the the simplified code in this patch.

| * crypto: blake2b - merge blake2 init to api callbackDavid Sterba2019-11-221-84/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The call chain from blake2b_init can be simplified because the param block is effectively zeros, besides the key. - blake2b_init0 zeroes state and sets IV - blake2b_init sets up param block with defaults (key and some 1s) - init with key, write it to the input buffer and recalculate state So the compact way is to zero out the state and initialize index 0 of the state directly with the non-zero values and the key.

| * int128: move __uint128_t compiler test to KconfigArd Biesheuvel2019-11-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to use 128-bit integer arithmetic in C code, the architecture needs to have declared support for it by setting ARCH_SUPPORTS_INT128, and it requires a version of the toolchain that supports this at build time. This is why all existing tests for ARCH_SUPPORTS_INT128 also test whether __SIZEOF_INT128__ is defined, since this is only the case for compilers that can support 128-bit integers. Let's fold this additional test into the Kconfig declaration of ARCH_SUPPORTS_INT128 so that we can also use the symbol in Makefiles, e.g., to decide whether a certain object needs to be included in the first place.

Instead, depend on the generic library so that we only reuse code without pulling in the generic skcipher implementation as well. While at it, remove the logic that prefers the non-SIMD path for short inputs - this is no longer necessary after recent FPU handling changes on x86. Since this removes the last remaining user of the routines exported by the generic shash driver, unexport them and make them static.

| * crypto: mips/chacha - wire up accelerated 32r2 code from ZincArd Biesheuvel2019-11-171-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This integrates the accelerated MIPS 32r2 implementation of ChaCha into both the API and library interfaces of the kernel crypto stack. The significance of this is that, in addition to becoming available as an accelerated library implementation, it can also be used by existing crypto API code such as Adiantum (for block encryption on ultra low performance cores) or IPsec using chacha20poly1305. These are use cases that have already opted into using the abstract crypto API. In order to support Adiantum, the core assembler routine has been adapted to take the round count as a function argument rather than hardcoding it to 20.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In preparation of extending the x86 ChaCha driver to also expose the ChaCha library interface, drop the dependency on the chacha_generic crypto driver as a non-SIMD fallback, and depend on the generic ChaCha library directly. This way, we only pull in the code we actually need, without registering a set of ChaCha skciphers that we will never use. Since turning the FPU on and off is cheap these days, simplify the SIMD routine by dropping the per-page yield, which makes for a cleaner switch to the library API as well. This also allows use to invoke the skcipher walk routines in non-atomic mode. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * crypto: chacha - move existing library code into lib/cryptoArd Biesheuvel2019-11-172-55/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, our generic ChaCha implementation consists of a permute function in lib/chacha.c that operates on the 64-byte ChaCha state directly [and which is always included into the core kernel since it is used by the /dev/random driver], and the crypto API plumbing to expose it as a skcipher. In order to support in-kernel users that need the ChaCha streamcipher but have no need [or tolerance] for going through the abstractions of the crypto API, let's expose the streamcipher bits via a library API as well, in a way that permits the implementation to be superseded by an architecture specific one if provided. So move the streamcipher code into a separate module in lib/crypto, and expose the init() and crypt() routines to users of the library.

| | | | | | | | | | | | | | | | | | | | | | | | | | If aead is built as a module along with cryptomgr, it creates a dependency loop due to the dependency chain aead => crypto_null => cryptomgr => aead.

| * crypto: skcipher - remove the "blkcipher" algorithm typeEric Biggers2019-11-017-664/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that all "blkcipher" algorithms have been converted to "skcipher", remove the blkcipher algorithm type. The skcipher (symmetric key cipher) algorithm type was introduced a few years ago to replace both blkcipher and ablkcipher (synchronous and asynchronous block cipher). The advantages of skcipher include: - A much less confusing name, since none of these algorithm types have ever actually been for raw block ciphers, but rather for all length-preserving encryption modes including block cipher modes of operation, stream ciphers, and other length-preserving modes. - It unified blkcipher and ablkcipher into a single algorithm type which supports both synchronous and asynchronous implementations. Note, blkcipher already operated only on scatterlists, so the fact that skcipher does too isn't a regression in functionality. - Better type safety by using struct skcipher_alg, struct crypto_skcipher, etc. instead of crypto_alg, crypto_tfm, etc. - It sometimes simplifies the implementations of algorithms. Also, the blkcipher API was no longer being tested. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

And they have exactly the same prototype. Therefore, eliminate the redundancy by removing crypto_has_skcipher() and renaming crypto_has_skcipher2() to crypto_has_skcipher().

| * crypto: testmgr - add test vectors for blake2bDavid Sterba2019-11-012-0/+335
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Test vectors for blake2b with various digest sizes. As the algorithm is the same up to the digest calculation, the key and input data length is distributed in a way that tests all combinanions of the two over the digest sizes. Based on the suggestion from Eric, the following input sizes are tested [0, 1, 7, 15, 64, 247, 256], where blake2b blocksize is 128, so the padded and the non-padded input buffers are tested. blake2b-160 blake2b-256 blake2b-384 blake2b-512 --------------------------------------------------- len=0 | klen=0 klen=1 klen=32 klen=64 len=1 | klen=32 klen=64 klen=0 klen=1 len=7 | klen=64 klen=0 klen=1 klen=32 len=15 | klen=1 klen=32 klen=64 klen=0 len=64 | klen=0 klen=1 klen=32 klen=64 len=247 | klen=32 klen=64 klen=0 klen=1 len=256 | klen=64 klen=0 klen=1 klen=32 Where key: - klen=0: empty key - klen=1: 1 byte value 0x42, 'B' - klen=32: first 32 bytes of the default key, sequence 00..1f - klen=64: default key, sequence 00..3f The unkeyed vectors are ordered before keyed, as this is required by testmgr.

| * crypto: blake2b - add blake2b generic implementationDavid Sterba2019-11-013-0/+453
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch brings support of several BLAKE2 variants (2b with various digest lengths). The keyed digest is supported, using tfm->setkey call. The in-tree user will be btrfs (for checksumming), we're going to use the BLAKE2b-256 variant. The code is reference implementation taken from the official sources and modified in terms of kernel coding style (whitespace, comments, uintXX_t -> uXX types, removed unused prototypes and #ifdefs, removed testing code, changed secure_zero_memory -> memzero_explicit, used own helpers for unaligned reads/writes and rotations). Further changes removed sanity checks of key length or output size, these values are verified in the crypto API callbacks or hardcoded in shash_alg and not exposed to users.

| * crypto: ecdh - fix big endian bug in ECC libraryArd Biesheuvel2019-11-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The elliptic curve arithmetic library used by the EC-DH KPP implementation assumes big endian byte order, and unconditionally reverses the byte and word order of multi-limb quantities. On big endian systems, the byte reordering is not necessary, while the word ordering needs to be retained. So replace the __swab64() invocation with a call to be64_to_cpu() which should do the right thing for both little and big endian builds.

This is needed in order for the blkcipher API to be removed. Tested with: export ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- make mpc85xx_defconfig cat >> .config << EOF # CONFIG_MODULES is not set # CONFIG_CRYPTO_MANAGER_DISABLE_TESTS is not set CONFIG_DEBUG_KERNEL=y CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y CONFIG_CRYPTO_AES=y CONFIG_CRYPTO_CBC=y CONFIG_CRYPTO_CTR=y CONFIG_CRYPTO_ECB=y CONFIG_CRYPTO_XTS=y CONFIG_CRYPTO_AES_PPC_SPE=y EOF make olddefconfig make -j32 qemu-system-ppc -M mpc8544ds -cpu e500 -nographic \ -kernel arch/powerpc/boot/zImage \ -append cryptomgr.fuzz_iterations=1000 Note that xts-ppc-spe still fails the comparison tests due to the lack of ciphertext stealing support. This is not addressed by this patch. This patch also cleans up the code by making ->encrypt() and ->decrypt() call a common function for each of ECB, CBC, and XTS, and by using a clearer way to compute the length to process at each step.
