2009-09-21crypto: padlock-sha - Fix stack alignmentHerbert Xu
The PadLock hardware requires the output buffer for SHA to be 128-bit aligned. We currentply place the buffer on the stack, and ask gcc to align it to 128 bits. That doesn't work on i386 because the kernel stack is only aligned to 32 bits. This patch changes the code to align the buffer by hand so that the hardware doesn't fault on unaligned buffers.

2009-07-16crypto: padlock - Fix hashing of partial blocksHerbert Xu
When we encounter partial blocks in finup, we'll invoke the xsha instruction with a bogus count that is not a multiple of the block size. This patch fixes it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2009-07-15crypto: padlock - Fix compile error on i386Herbert Xu
The previous change to allow hashing from states other than the initial broke compilation on i386 because the inline assembly tried to squeeze a u64 into a 32-bit register. As we've already checked for 32-bit overflows we can simply truncate it to u32, or unsigned long so that we don't truncate at all on x86-64. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2009-07-15crypto: crypto4xx - Disable SHA implementationHerbert Xu
The crypto4xx SHA implementation keeps the hash state in the tfm data structure. This breaks a fundamental requirement of ahash implementations that they must be reentrant. This patch disables the broken implementation. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2009-07-14crypto: crypto4xx - Switch to new style ahashHerbert Xu
This patch changes crypto4xx to use the new style ahash type. In particular, we now use ahash_alg to define ahash algorithms instead of crypto_alg. This is achieved by introducing a union that encapsulates the new type and the existing crypto_alg structure. They're told apart through a u32 field containing the type value. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2009-07-14crypto: crypto4xx - Use crypto_ahash_set_reqsizeHerbert Xu
This patch makes crypto4xx use crypto_ahash_set_reqsize to avoid accessing crypto_ahash directly. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2009-07-14crypto: padlock - Switch sha to shashHerbert Xu
This patch converts the padlock-sha implementation to shash. In doing so the existing mechanism of storing the data until final is no longer viable as we do not have a way of allocating data in crypto_shash_init and then reliably freeing it. This is just as well because a better way of handling the problem is to hash everything but the last chunk using normal sha code and then provide the intermediate result to the padlock device. This is good enough because the primary application of padlock-sha is IPsec and there the data is laid out in the form of an hmac header followed by the rest of the packet. In essence we can provide all the data to the padlock as the hmac header only needs to be hashed once. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2009-02-26crypto: api - Fix module load deadlock with fallback algorithmsHerbert Xu
With the mandatory algorithm testing at registration, we have now created a deadlock with algorithms requiring fallbacks. This can happen if the module containing the algorithm requiring fallback is loaded first, without the fallback module being loaded first. The system will then try to test the new algorithm, find that it needs to load a fallback, and then try to load that. As both algorithms share the same module alias, it can attempt to load the original algorithm again and block indefinitely. As algorithms requiring fallbacks are a special case, we can fix this by giving them a different module alias than the rest. Then it's just a matter of using the right aliases according to what algorithms we're trying to find. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2008-12-25crypto: talitos - Ack done interrupt in isr instead of taskletLee Nipper
Previous commit for interrupt mitigation moved the done interrupt acknowlegement from the isr to the talitos_done tasklet. This patch moves the done interrupt acknowledgement back into the isr so that done interrupts will always be acknowledged. This covers the case for acknowledging interrupts for channel done processing that has actually already been completed by the tasklet prior to fielding a pending interrupt.

2008-12-25crypto: padlock - Avoid resetting cword on successive operationsHerbert Xu
Resetting the control word is quite expensive. Fortunately this isn't an issue for the common operations such as CBC and ECB as the whole operation is done through a single call. However, modes such as LRW and XTS have to call padlock over and over again for one operation which really hurts if each call resets the control word. This patch uses an idea by Sebastian Siewior to store the last control word used on a CPU and only reset the control word if that changes. Note that any task switch automatically resets the control word so we only need to be accurate with regard to the stored control word when no task switches occur.
