The LRW template now wraps an ECB mode algorithm rather than the block cipher directly. Therefore it is now redundant for crypto modules to wrap their ECB code with generic LRW code themselves via lrw_crypt(). Remove the lrw-camellia-asm algorithm which did this. Users who request lrw(camellia) and previously would have gotten lrw-camellia-asm will now get lrw(ecb-camellia-asm) instead, which is just as fast. Signed-off-by:

With ecb-cast5-avx, if a 128+ byte scatterlist element followed a shorter one, then the algorithm accidentally encrypted/decrypted only 8 bytes instead of the expected 128 bytes. Fix it by setting the encryption/decryption 'fn' correctly. Fixes: c12ab20b ("crypto: cast5/avx - avoid using temporary stack buffers") Cc: <stable@vger.kernel.org> # v3.8+ Signed-off-by:

Add ECB, CBC, and CTR functions to glue_helper which use skcipher_walk rather than blkcipher_walk. This will allow converting the remaining x86 algorithms from the blkcipher interface over to the skcipher interface, after which we'll be able to remove the blkcipher_walk versions of these functions.

Add a function to crypto_simd that registers an array of skcipher algorithms, then allocates and registers the simd wrapper algorithms for them. It assumes the naming scheme where the names of the underlying algorithms are prefixed with two underscores. Also add the corresponding 'unregister' function. Most of the x86 crypto modules will be able to use these. Signed-off-by:

Add test vectors for Speck64-XTS, generated in userspace using C code. The inputs were borrowed from the AES-XTS test vectors, with key lengths adjusted. xts-speck64-neon passes these tests. However, they aren't currently applicable for the generic XTS template, as that only supports a 128-bit block size. Signed-off-by:

Add an ARM NEON-accelerated implementation of Speck-XTS. It operates on 128-byte chunks at a time, i.e. 8 blocks for Speck128 or 16 blocks for Speck64. Each 128-byte chunk goes through XTS preprocessing, then is encrypted/decrypted (doing one cipher round for all the blocks, then the next round, etc.), then goes through XTS postprocessing. The performance depends on the processor but can be about 3 times faster than the generic code. For example, on an ARMv7 processor we observe the following performance with Speck128/256-XTS: xts-speck128-neon: Encryption 107.9 MB/s, Decryption 108.1 MB/s xts(speck128-generic): Encryption 32.1 MB/s, Decryption 36.6 MB/s In comparison to AES-256-XTS without the Cryptography Extensions: xts-aes-neonbs: Encryption 41.2 MB/s, Decryption 36.7 MB/s xts(aes-asm): Encryption 31.7 MB/s, Decryption 30.8 MB/s xts(aes-generic): Encryption 21.2 MB/s, Decryption 20.9 MB/s Speck64/128-XTS is even faster: xts-speck64-neon: Encryption 138.6 MB/s, Decryption 139.1 MB/s Note that as with the generic code, only the Speck128 and Speck64 variants are supported. Also, for now only the XTS mode of operation is supported, to target the disk and file encryption use cases. The NEON code also only handles the portion of the data that is evenly divisible into 128-byte chunks, with any remainder handled by a C fallback. Of course, other modes of operation could be added later if needed, and/or the NEON code could be updated to handle other buffer sizes. The XTS specification is only defined for AES which has a 128-bit block size, so for the GF(2^64) math needed for Speck64-XTS we use the reducing polynomial 'x^64 + x^4 + x^3 + x + 1' given by the original XEX paper. Of course, when possible users should use Speck128-XTS, but even that may be too slow on some processors; Speck64-XTS can be faster. Signed-off-by: -

Export the Speck constants and transform context and the ->setkey(), ->encrypt(), and ->decrypt() functions so that they can be reused by the ARM NEON implementation of Speck-XTS. The generic key expansion code will be reused because it is not performance-critical and is not vectorizable, while the generic encryption and decryption functions are needed as fallbacks and for the XTS tweak encryption.
