* crypto: scatterwalk - Add support for calculating number of SG elementsJoel Fernandes2013-08-211-0/+22
| | | | | | | | | Crypto layer only passes nbytes to encrypt but in omap-aes driver we need to know number of SG elements to pass to dmaengine slave API. We add function for the same to scatterwalk library. Signed-off-by: Joel Fernandes <joelf@ti.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds unaligned buffer tests for hashes.

The previous 8-way twofish/AVX implementation is therefore faster and this implementation should be removed.

The use of wait_for_completion_interruptible is intentional so that we don't lock up the thread if a bug causes us to never wake up. This bug is caused by the helper thread using the larval without holding a reference count on it. If the helper thread completes after the original thread requesting for help has gone away and destroyed the larval, then we get the crash above. So the fix is to hold a reference count on the larval.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | camellia cipher Patch adds AVX2/AES-NI/x86-64 implementation of Camellia cipher, requiring 32 parallel blocks for input (512 bytes). Compared to AVX implementation, this version is extended to use the 256-bit wide YMM registers. For AES-NI instructions data is split to two 128-bit registers and merged afterwards. Even with this additional handling, performance should be higher compared to the AES-NI/AVX implementation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch adds AVX2/x86-64 implementation of Serpent cipher, requiring 16 parallel blocks for input (256 bytes). Implementation is based on the AVX implementation and extends to use the 256-bit wide YMM registers. Since serpent does not use table look-ups, this implementation should be close to two times faster than the AVX implementation.

Table look-ups are performed using vpgatherdd instruction directly from vector registers and thus should be faster than earlier implementations. Implementation also uses 256-bit wide YMM registers, which should give additional speed up compared to the AVX implementation.
