Linux-2.6.12-rc2 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!

[CRYPTO] Add null short circuit to crypto_free_tfm As far as I'm aware there's a general concensus that functions that are responsible for freeing resources should be able to cope with being passed a NULL pointer. This makes sense as it removes the need for all callers to check for NULL, thus elliminating the bugs that happen when some forget (safer to just check centrally in the freeing function) and it also makes for smaller code all over due to the lack of all those NULL checks. This patch makes it safe to pass the crypto_free_tfm() function a NULL pointer. Once this patch is applied we can start removing the NULL checks from the callers.

[CRYPTO] Ensure cit_iv is aligned correctly 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>

[CRYPTO] Add alignmask for low-level cipher implementations The VIA Padlock device requires the input and output buffers to be aligned on 16-byte boundaries. This patch adds the alignmask attribute for low-level cipher implementations to indicate their alignment requirements. The mid-level crypt() function will copy the input/output buffers if they are not aligned correctly before they are passed to the low-level implementation. Strictly speaking, some of the software implementations require the buffers to be aligned on 4-byte boundaries as they do 32-bit loads. However, it is not clear whether it is better to copy the buffers or pay the penalty for unaligned loads/stores. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
