[CRYPTO] aead: Add authenc This patch adds the authenc algorithm which constructs an AEAD algorithm from an asynchronous block cipher and a hash. The construction is done by concatenating the encrypted result from the cipher with the output from the hash, as is used by the IPsec ESP protocol. The authenc algorithm exists as a template with four parameters: authenc(auth, authsize, enc, enckeylen). The authentication algorithm, the authentication size (i.e., truncating the output of the authentication algorithm), the encryption algorithm, and the encryption key length. Both the size field and the key length field are in bytes. For example, AES-128 with SHA1-HMAC would be represented by authenc(hmac(sha1), 12, cbc(aes), 16) The key for the authenc algorithm is the concatenation of the keys for the authentication algorithm with the encryption algorithm. For the above example, if a key of length 36 bytes is given, then hmac(sha1) would receive the first 20 bytes while the last 16 would be given to cbc(aes).

[CRYPTO] authenc: Use crypto_grab_skcipher This patch converts the authenc algorithm over to crypto_grab_skcipher which is a prerequisite for IV generation.

[CRYPTO] authenc: Move enckeylen into key itself Having enckeylen as a template parameter makes it a pain for hardware devices that implement ciphers with many key sizes since each one would have to be registered separately. Since the authenc algorithm is mainly used for legacy purposes where its key is going to be constructed out of two separate keys, we can in fact embed this value into the key itself. This patch does this by prepending an rtnetlink header to the key that contains the encryption key length. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: authenc - Add EINPROGRESS check When Steffen originally wrote the authenc async hash patch, he correctly had EINPROGRESS checks in place so that we did not invoke the original completion handler with it. Unfortuantely I told him to remove it before the patch was applied. As only MAY_BACKLOG request completion handlers are required to handle EINPROGRESS completions, those checks are really needed. This patch restores them. Reported-by: Sebastian Andrzej Siewior <sebastian@breakpoint.cc> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

[CRYPTO] aead: Add authenc This patch adds the authenc algorithm which constructs an AEAD algorithm from an asynchronous block cipher and a hash. The construction is done by concatenating the encrypted result from the cipher with the output from the hash, as is used by the IPsec ESP protocol. The authenc algorithm exists as a template with four parameters: authenc(auth, authsize, enc, enckeylen). The authentication algorithm, the authentication size (i.e., truncating the output of the authentication algorithm), the encryption algorithm, and the encryption key length. Both the size field and the key length field are in bytes. For example, AES-128 with SHA1-HMAC would be represented by authenc(hmac(sha1), 12, cbc(aes), 16) The key for the authenc algorithm is the concatenation of the keys for the authentication algorithm with the encryption algorithm.

[CRYPTO] authenc: Move enckeylen into key itself Having enckeylen as a template parameter makes it a pain for hardware devices that implement ciphers with many key sizes since each one would have to be registered separately. Since the authenc algorithm is mainly used for legacy purposes where its key is going to be constructed out of two separate keys, we can in fact embed this value into the key itself. This patch does this by prepending an rtnetlink header to the key that contains the encryption key length. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: authenc - Avoid using clobbered request pointer Authenc works in two stages for encryption, it first encrypts and then computes an ICV. The context memory of the request is used by both operations. The problem is that when an asynchronous encryption completes, we will compute the ICV and then reread the context memory of the encryption to get the original request. It just happens that we have a buffer of 16 bytes in front of the request pointer, so ICVs of 16 bytes (such as SHA1) do not trigger the bug. However, any attempt to uses a larger ICV instantly kills the machine when the first asynchronous encryption is completed. This patch fixes this by saving the request pointer before we start the ICV computation. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

[CRYPTO] aead: Add authenc This patch adds the authenc algorithm which constructs an AEAD algorithm from an asynchronous block cipher and a hash. The construction is done by concatenating the encrypted result from the cipher with the output from the hash, as is used by the IPsec ESP protocol. The authenc algorithm exists as a template with four parameters: authenc(auth, authsize, enc, enckeylen). The authentication algorithm, the authentication size (i.e., truncating the output of the authentication algorithm), the encryption algorithm, and the encryption key length. Both the size field and the key length field are in bytes. For example, AES-128 with SHA1-HMAC would be represented by authenc(hmac(sha1), 12, cbc(aes), 16) The key for the authenc algorithm is the concatenation of the keys for the authentication algorithm with the encryption algorithm. For the above example, if a key of length 36 bytes is given, then hmac(sha1) would receive the first 20 bytes while the last 16 would be given to cbc(aes).

[CRYPTO] aead: Add authenc This patch adds the authenc algorithm which constructs an AEAD algorithm from an asynchronous block cipher and a hash. The construction is done by concatenating the encrypted result from the cipher with the output from the hash, as is used by the IPsec ESP protocol. The authenc algorithm exists as a template with four parameters: authenc(auth, authsize, enc, enckeylen). The authentication algorithm, the authentication size (i.e., truncating the output of the authentication algorithm), the encryption algorithm, and the encryption key length. Both the size field and the key length field are in bytes. For example, AES-128 with SHA1-HMAC would be represented by authenc(hmac(sha1), 12, cbc(aes), 16) The key for the authenc algorithm is the concatenation of the keys for the authentication algorithm with the encryption algorithm. For the above example, if a key of length 36 bytes is given, then hmac(sha1) would receive the first 20 bytes while the last 16 would be given to cbc(aes).

[CRYPTO] authenc: Move enckeylen into key itself Having enckeylen as a template parameter makes it a pain for hardware devices that implement ciphers with many key sizes since each one would have to be registered separately. Since the authenc algorithm is mainly used for legacy purposes where its key is going to be constructed out of two separate keys, we can in fact embed this value into the key itself. This patch does this by prepending an rtnetlink header to the key that contains the encryption key length. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

The authenc algorithm exists as a template with four parameters: authenc(auth, authsize, enc, enckeylen). The authentication algorithm, the authentication size (i.e., truncating the output of the authentication algorithm), the encryption algorithm, and the encryption key length. Both the size field and the key length field are in bytes. For example, AES-128 with SHA1-HMAC would be represented by authenc(hmac(sha1), 12, cbc(aes), 16) The key for the authenc algorithm is the concatenation of the keys for the authentication algorithm with the encryption algorithm. For the above example, if a key of length 36 bytes is given, then hmac(sha1) would receive the first 20 bytes while the last 16 would be given to cbc(aes).

[CRYPTO] aead: Add authenc This patch adds the authenc algorithm which constructs an AEAD algorithm from an asynchronous block cipher and a hash.
