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] hmac: Add crypto template implementation This patch rewrites HMAC as a crypto template. This means that HMAC is no longer a hard-coded part of the API. It's now a template that generates standard digest algorithms like any other. The old HMAC is preserved until all current users are converted. The same structure can be used by other MACs such as AES-XCBC-MAC. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

[CRYPTO] hmac: Avoid calling virt_to_page on key When HMAC gets a key longer than the block size of the hash, it needs to feed it as input to the hash to reduce it to a fixed length. As it is HMAC converts the key to a scatter and gather list. However, this doesn't work on certain platforms if the key is not allocated via kmalloc. For example, the keys from tcrypt are stored in the rodata section and this causes it to fail with HMAC on x86-64. This patch fixes this by copying the key to memory obtained via kmalloc before hashing it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: hash - Fixed digest size check The digest size check on hash algorithms is incorrect. It's perfectly valid for hash algorithms to have a digest length longer than their block size. For example crc32c has a block size of 1 and a digest size of 4. Rather than having it lie about its block size, this patch fixes the checks to do what they really should which is to bound the digest size so that code placing the digest on the stack continue to work. HMAC however still needs to check this as it's only defined for such algorithms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: hash - Fixed digest size check The digest size check on hash algorithms is incorrect. It's perfectly valid for hash algorithms to have a digest length longer than their block size. For example crc32c has a block size of 1 and a digest size of 4. Rather than having it lie about its block size, this patch fixes the checks to do what they really should which is to bound the digest size so that code placing the digest on the stack continue to work. HMAC however still needs to check this as it's only defined for such algorithms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

[CRYPTO] hmac: Add crypto template implementation This patch rewrites HMAC as a crypto template. This means that HMAC is no longer a hard-coded part of the API. It's now a template that generates standard digest algorithms like any other. The old HMAC is preserved until all current users are converted. The same structure can be used by other MACs such as AES-XCBC-MAC. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
