2015-05-22crypto: scatterwalk - Check for same address in map_and_copyHerbert Xu
This patch adds a check for in scatterwalk_map_and_copy to avoid copying from the same address to the same address. This is going to be used for IV copying in AEAD IV generators. There is no provision for partial overlaps. This patch also uses the new scatterwalk_ffwd instead of doing it by hand in scatterwalk_map_and_copy.

2015-05-22crypto: gcm - Use default null skcipherHerbert Xu
This patch makes gcm use the default null skcipher instead of allocating a new one for each tfm. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-05-22crypto: null - Add default null skcipherHerbert Xu
This patch adds a default null skcipher for users such as gcm to perform copies on SG lists. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-05-22crypto: aead - Add support for new AEAD implementationsHerbert Xu
This patch adds the basic structure of the new AEAD type. Unlike the current version, there is no longer any concept of geniv. IV generation will still be carried out by wrappers but they will be normal AEAD algorithms that simply take the IPsec sequence number as the IV.

2015-05-22crypto: nx - Remove unnecessary maxauthsize checkHerbert Xu
The crypto layer already checks maxauthsize when setauthsize is called. So there is no need to check it again within setauthsize. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-05-22crypto: ixp4xx - Use crypto_aead_maxauthsizeHerbert Xu
This patch uses the helper crypto_aead_maxauthsize instead of directly dereferencing aead_alg. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-05-22crypto: aead - Add crypto_aead_maxauthsizeHerbert Xu
This patch adds the helper crypto_aead_maxauthsize to remove the need to directly dereference aead_alg internals by AEAD implementors. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-05-22crypto: caam - Use old_aead_algHerbert Xu
This patch replaces references to aead_alg with old_aead_alg. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-05-22crypto: aead - Rename aead_alg to old_aead_algHerbert Xu
This patch is the first step in the introduction of a new AEAD alg type. Unlike normal conversions this patch only renames the existing aead_alg structure because there are external references to it. Those references will be removed after this patch. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-05-22crypto: aead - Add new interface with single SG listHerbert Xu
The primary user of AEAD, IPsec includes the IV in the AD in most cases, except where it is implicitly authenticated by the underlying algorithm. The way it is currently implemented is a hack because we pass the data in piecemeal and the underlying algorithms try to stitch them back up into one piece. This is why this patch is adding a new interface that allows a single SG list to be passed in that contains everything so the algorithm implementors do not have to stitch. The new interface accepts a single source SG list and a single destination SG list. Both must be laid out as follows: AD, skipped data, plain/cipher text, ICV The ICV is not present from the source during encryption and from the destination during decryption. For the top-level IPsec AEAD algorithm the plain/cipher text will contain the generated (or received) IV. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-05-22crypto: scatterwalk - Add scatterwalk_ffwd helperHerbert Xu
This patch adds the scatterwalk_ffwd helper which can create an SG list that starts in the middle of an existing SG list. The new list may either be part of the existing list or be a chain that latches onto part of the existing list. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-05-22crypto: pcrypt - Use crypto_grab_aeadHerbert Xu
As AEAD has switched over to using frontend types, the function crypto_init_spawn must not be used since it does not specify a frontend type. Otherwise it leads to a crash when the spawn is used. This patch fixes it by switching over to crypto_grab_aead instead.

2015-05-22crypto: s390/ghash - Fix incorrect ghash icv buffer handling.Harald Freudenberger
Multitheaded tests showed that the icv buffer in the current ghash implementation is not handled correctly. A move of this working ghash buffer value to the descriptor context fixed this.

This reverts commit 7291a932c6e27d9768e374e9d648086636daf61c. The conversion to be16_add_cpu() is incorrect in case cryptlen is negative due to premature (i.e. before addition / subtraction) implicit conversion of cryptlen (int -> u16) leading to sign loss.
