[CRYPTO] api: Get rid of flags argument to setkey

2006-09-21T01:41:02+00:00

Now that the tfm is passed directly to setkey instead of the ctx, we no longer need to pass the &tfm->crt_flags pointer. This patch also gets rid of a few unnecessary checks on the key length for ciphers as the cipher layer guarantees that the key length is within the bounds specified by the algorithm. Rather than testing dia_setkey every time, this patch does it only once during crypto_alloc_tfm. The redundant check from crypto_digest_setkey is also removed. Signed-off-by: Herbert Xu

[CRYPTO] twofish: x86-64 assembly version

2006-09-21T01:16:29+00:00

The patch passed the trycpt tests and automated filesystem tests. This rewrite resulted in some nice perfomance increase over my last patch. Short summary of the tcrypt benchmarks: Twofish Assembler vs. Twofish C (256bit 8kb block CBC) encrypt: -27% Cycles decrypt: -23% Cycles Twofish Assembler vs. AES Assembler (128bit 8kb block CBC) encrypt: +18% Cycles decrypt: +15% Cycles Twofish Assembler vs. AES Assembler (256bit 8kb block CBC) encrypt: -9% Cycles decrypt: -8% Cycles Full Output: http://homepages.tu-darmstadt.de/~fritschi/twofish/tcrypt-speed-twofish-c-x86_64.txt http://homepages.tu-darmstadt.de/~fritschi/twofish/tcrypt-speed-twofish-asm-x86_64.txt http://homepages.tu-darmstadt.de/~fritschi/twofish/tcrypt-speed-aes-asm-x86_64.txt Here is another bonnie++ benchmark with encrypted filesystems. Most runs maxed out the hd. It should give some idea what the module can do for encrypted filesystem performance even though you can't see the full numbers. http://homepages.tu-darmstadt.de/~fritschi/twofish/output_20060610_130806_x86_64.html Signed-off-by: Joachim Fritschi Signed-off-by: Herbert Xu

[CRYPTO] aes: Add wrappers for assembly routines

2006-06-26T07:34:42+00:00

The wrapper routines are required when asmlinkage differs from the usual calling convention. So we need to have them. However, by rearranging the parameters, they will get optimised away to a single jump for most people. Signed-off-by: Herbert Xu
