[PATCH 28/30] crypto: skcipher - Add skcipher walk interface

This patch adds the skcipher walk interface which replaces both blkcipher walk and ablkcipher walk. Just like blkcipher walk it can also be used for AEAD algorithms. Signed-off-by: Herbert Xu --- crypto/skcipher.c | 506

[PATCH 26/30] crypto: scatterwalk - Remove unnecessary BUG in scatterwalk_start

Nothing bad will happen even if sg->length is zero, so there is no point in keeping this BUG_ON in scatterwalk_start. Signed-off-by: Herbert Xu --- crypto/scatterwalk.c |3 --- 1 file changed, 3 deletions(-) diff --git a/crypto/scatterwalk.c

[PATCH 24/30] crypto: scatterwalk - Fix test in scatterwalk_done

When there is more data to be processed, the current test in scatterwalk_done may prevent us from calling pagedone even when we should. In particular, if we're on an SG entry spanning multiple pages where the last page is not a full page, we will incorrectly skip calling pagedone on the second

[PATCH 29/30] crypto: aes-ce-ccm - Use skcipher walk interface

[PATCH 30/30] crypto: lrw - Convert to skcipher

This patch converts lrw over to the skcipher interface. It also optimises the implementation to be based on ECB instead of the underlying cipher. For compatibility the existing naming scheme of lrw(aes) is maintained as opposed to the more obvious one of lrw(ecb(aes)). Signed-off-by: Herbert Xu

[PATCH 25/30] crypto: scatterwalk - Remove unnecessary advance in scatterwalk_pagedone

The offset advance in scatterwalk_pagedone not only is unnecessary, but it was also buggy when it was needed by scatterwalk_copychunks. As the latter has long ago been fixed to call scatterwalk_advance directly, we can remove this unnecessary offset adjustment. Signed-off-by: Herbert Xu

[PATCH 27/30] crypto: scatterwalk - Inline start/map/done

This patch inlines the functions scatterwalk_start, scatterwalk_map and scatterwalk_done as they're all tiny and mostly used by the block cipher walker. Signed-off-by: Herbert Xu --- crypto/scatterwalk.c | 43

[PATCH 23/30] crypto: api - Optimise away crypto_yield when hard preemption is on

When hard preemption is enabled there is no need to explicitly call crypto_yield. This patch eliminates it if that is the case. Signed-off-by: Herbert Xu --- include/crypto/algapi.h |2 ++ 1 file changed, 2 insertions(+) diff --git a/include/crypto/algapi.h

[PATCH 11/30] crypto: aead - Add skcipher null for IV generators

[PATCH 5/30] crypto: authencesn - Use skcipher

This patch converts authencesn to use the new skcipher interface as opposed to ablkcipher. It also fixes a little bug where if a sync version of authencesn is requested we may still end up using an async ahash. This should have no effect as none of the authencesn users can request for a sync

[PATCH 18/30] crypto: skcipher - Remove top-level givcipher interface

This patch removes the old crypto_grab_skcipher helper and replaces it with crypto_grab_skcipher2. As this is the final entry point into givcipher this patch also removes all traces of the top-level givcipher interface, including all implicit IV generators such as chainiv. The bottom-level

[PATCH 20/30] crypto: omap - Stop using crypto scatterwalk_bytes_sglen

We already have a generic function sg_nents_for_len which does the same thing. This patch switches omap over to it and also adds error handling in case the SG list is short. Signed-off-by: Herbert Xu --- drivers/crypto/omap-aes.c | 16 ++--

[PATCH 16/30] crypto: cts - Convert to skcipher

[PATCH 3/30] crypto: aead - Add chunk size
