[CRYPTO] Check cra_alignmask against cra_blocksize

2005-10-30T00:19:43Z

The cipher code relies on the fact that the block size is a multiple of the required alignment. So we should check this at the time of algorith registration. We also ensure that the block size is bounded by the page size. Signed-off-by: Herbert Xu

[CRYPTO] Simplify one-member scatterlist expressions

2005-10-30T00:19:43Z

This patch rewrites various occurences of &sg[0] where sg is an array of length one to simply sg. Signed-off-by: Herbert Xu

[PATCH] Use sg_set_buf/sg_init_one where applicable

2005-10-30T00:19:43Z

This patch uses sg_set_buf/sg_init_one in some places where it was duplicated. Signed-off-by: David Hardeman Cc: James Bottomley Cc: Greg KH Cc: "David S. Miller" Cc: Jeff Garzik Signed-off-by: Andrew Morton Signed-off-by: Herbert Xu

[CRYPTO] Fix boundary check in standard multi-block cipher processors

2005-09-06T21:49:44Z

The boundary check in the standard multi-block cipher processors are broken when nbytes is not a multiple of bsize. In those cases it will always process an extra block. This patch corrects the check so that it processes at most nbytes of data. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

[CRYPTO]: Added CRYPTO_TFM_REQ_MAY_SLEEP flag

2005-09-02T00:43:05Z

The crypto layer currently uses in_atomic() to determine whether it is allowed to sleep. This is incorrect since spin locks don't always cause in_atomic() to return true. Instead of that, this patch returns to an earlier idea of a per-tfm flag which determines whether sleeping is allowed. Unlike the earlier version, the default is to not allow sleeping. This ensures that no existing code can break. As usual, this flag may either be set through crypto_alloc_tfm(), or just before a specific crypto operation.

[CRYPTO]: Fix XTEA implementation

2005-09-02T00:42:46Z

The XTEA implementation was incorrect due to a misinterpretation of operator precedence. Because of the wide-spread nature of this error, the erroneous implementation will be kept, albeit under the new name of XETA.

[PATCH] clean up inline static vs static inline

2005-07-27T23:26:20Z

`gcc -W' likes to complain if the static keyword is not at the beginning of the declaration. This patch fixes all remaining occurrences of "inline static" up with "static inline" in the entire kernel tree (140 occurrences in 47 files). While making this change I came across a few lines with trailing whitespace that I also fixed up, I have also added or removed a blank line or two here and there, but there are no functional changes in the patch.

[CRYPTO] Add faster DES code from Dag Arne Osvik

2005-07-06T20:55:44Z

I've made a new implementation of DES to replace the old one in the kernel. It provides faster encryption on all tested processors apart from the original Pentium, and key setup is many times faster.
