2018-03-02crypto: x86/glue_helper - rename glue_skwalk_fpu_begin()Eric Biggers1-12/+9
There are no users of the original glue_fpu_begin() anymore, so rename glue_skwalk_fpu_begin() to glue_fpu_begin() so that it matches glue_fpu_end() again. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2018-03-02crypto: x86/glue_helper - remove blkcipher_walk functionsEric Biggers1-344/+0
Now that all glue_helper users have been switched from the blkcipher interface over to the skcipher interface, remove the versions of the glue_helper functions that handled the blkcipher interface.

2018-03-02crypto: lrw - remove lrw_crypt()Eric Biggers1-1/+0
Now that all users of lrw_crypt() have been removed in favor of the LRW template wrapping an ECB mode algorithm, remove lrw_crypt(). Also remove crypto/lrw.h as that is no longer needed either; and fold 'struct lrw_table_ctx' into 'struct priv', lrw_init_table() into setkey(), and lrw_free_table() into exit_tfm().

2018-03-02crypto: x86/glue_helper - add skcipher_walk functionsEric Biggers1-0/+207
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.

2017-06-19crypto: glue_helper - Delete some dead codeDan Carpenter1-3/+0
We checked (nbytes < bsize) inside the loops so it's not possible to hit the "goto done;" here. This code is cut and paste from other slightly different loops where we don't have the check inside the loop.

2017-04-05crypto: glue_helper - remove the le128_gf128mul_x_ble functionOndrej Mosnáček1-1/+2
The le128_gf128mul_x_ble function in glue_helper.h is now obsolete and can be replaced with the gf128mul_x_ble function from gf128mul.h. Signed-off-by: Ondrej Mosnacek <omosnacek@gmail.com> Reviewd-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2016-11-28crypto: glue_helper - Add skcipher xts helpersHerbert Xu1-1/+73
This patch adds xts helpers that use the skcipher interface rather than blkcipher. This will be used by aesni_intel. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2013-04-25crypto: x86 - add more optimized XTS-mode for serpent-avxJussi Kivilinna1-1/+96
This patch adds AVX optimized XTS-mode helper functions/macros and converts serpent-avx to use the new facilities. Benefits are slightly improved speed and reduced stack usage as use of temporary IV-array is avoided. tcrypt results, with Intel i5-2450M: enc dec 16B 1.00x 1.00x 64B 1.00x 1.00x 256B 1.04x 1.06x 1024B 1.09x 1.09x 8192B 1.10x 1.09x Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2012-10-24crypto: x86/glue_helper - use le128 instead of u128 for CTR modeJussi Kivilinna1-6/+6
'u128' currently used for CTR mode is on little-endian 'long long' swapped and would require extra swap operations by SSE/AVX code. Use of le128 instead of u128 allows IV calculations to be done with vector registers easier.

2012-10-04crypto: x86/glue_helper - fix storing of new IV in CBC encryptionJussi Kivilinna1-1/+1
Glue_helper incorrectly XORs new IV over old IV at end of CBC encryption function when it should store. This causes CBC encryption to give incorrect output on multi-page encryption requests.

Now that serpent-sse2 glue code has been made generic, it can be split to separate module. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
