2006-02-22[PATCH] padlock: Fix typo that broke 256-bit keysHerbert Xu
A typo crept into the le32_to_cpu patch which broke 256-bit keys in the padlock driver. The following patch based on observations by Michael Heyse fixes the problem. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-01-09[CRYPTO] Allow AES C/ASM implementations to coexistHerbert Xu
As the Crypto API now allows multiple implementations to be registered for the same algorithm, we no longer have to play tricks with Kconfig to select the right AES implementation. This patch sets the driver name and priority for all the AES implementations and removes the Kconfig conditions on the C implementation for AES.

2006-01-09[CRYPTO] Use standard byte order macros wherever possibleHerbert Xu
A lot of crypto code needs to read/write a 32-bit/64-bit words in a specific gender. Many of them open code them by reading/writing one byte at a time. This patch converts all the applicable usages over to use the standard byte order macros. This is based on a previous patch by Denis Vlasenko. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2006-01-09[PADLOCK] Fix sparse warning about 1-bit signed bit-fieldHerbert Xu
Change the bit-field in struct cword to unsigned to shut sparse up. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2005-10-30[PATCH] CONFIG_IA32Brian Gerst
Add CONFIG_X86_32 for i386. This allows selecting options that only apply to 32-bit systems. (X86 && !X86_64) becomes X86_32 (X86 || X86_64) becomes X86 Signed-off-by: Brian Gerst <bgerst@didntduck.org> Cc: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-07-06[CRYPTO] Update IV correctly for Padlock CBC encryptionHerbert Xu
When the Padlock does CBC encryption, the memory pointed to by EAX is not updated at all. Instead, it updates the value of EAX by pointing it to the last block in the output. Therefore to maintain the correct semantics we need to copy the IV. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-07-06[CRYPTO] Ensure cit_iv is aligned correctlyHerbert Xu
This patch ensures that cit_iv is aligned according to cra_alignmask by allocating it as part of the tfm structure. As a side effect the crypto layer will also guarantee that the tfm ctx area has enough space to be aligned by cra_alignmask. This allows us to remove the extra space reservation from the Padlock driver. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-07-06[PADLOCK] Implement multi-block operationsHerbert Xu
By operating on multiple blocks at once, we expect to extract more performance out of the VIA Padlock. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-07-06[PADLOCK] Move fast path work into aes_set_key and upper layerHerbert Xu
Most of the work done aes_padlock can be done in aes_set_key. This means that we only have to do it once when the key changes rather than every time we perform an encryption or decryption. This patch also sets cra_alignmask to let the upper layer ensure that the buffers fed to us are aligned correctly. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
