[PATCH 1/2] crypto: api - Add crypto_type_has_alg helper

This patch adds the helper crypto_type_has_alg which is meant to replace crypto_has_alg for new-style crypto types. Rather than hard-coding type/mask information they're now retrieved from the crypto_type object. Signed-off-by: Herbert Xu diff --git a/crypto/algapi.c b/crypto/algapi.c index 7be

[PATCH] crypto: skcipher - Add helper to zero stack request

As the size of an skcipher_request is variable, it's awkward to zero it explicitly. This patch adds a helper to do that which should be used when it is created on the stack. Signed-off-by: Herbert Xu diff --git a/include/crypto/skcipher.h b/include/crypto/skcipher.h index 2f07b4f..905490c 10064

Non-destructive ChaCha20Poly1305 Decryption

Hi Martin, Your ChaCha20Poly1305 implementation when decrypting calls chacha20 decryption before it verifies the auth tag. Not only does this waste CPU cycles, but it makes it impossible to attempt decryption of cipher texts using different keys (until one is right) without creating a copy, which

Crypto Fixes for 4.5

Hi Linus: This push fixes the following issues: API: * A large number of bug fixes for the af_alg interface, credit goes to Dmitry Vyukov for discovering and reporting these issues. Algorithms: * sw842 needs to select crc32. * The soft dependency on crc32c is now in the correct spot. Drivers:

[PATCH] crypto: drbg - remove FIPS 140-2 continuous test

Hi, the following patch is fully CAVS tested on 64 bit and 32 bit. Note, this change cannot be made for random.c or ansi_cprng.c, unfortunately. ---8<--- The newly released FIPS 140-2 IG 9.8 specifies that for SP800-90A compliant DRBGs, the FIPS 140-2 continuous random number generator test is n
