Pull powerpc updates from Benjamin Herrenschmidt: "So from the depth of frozen Minnesota, here's the powerpc pull request for 3.9. It has a few interesting highlights, in addition to the usual bunch of bug fixes, minor updates, embedded device tree updates and new boards: - Hand tuned asm implementation of SHA1 (by Paulus & Michael Ellerman) - Support for Doorbell interrupts on Power8 (kind of fast thread-thread IPIs) by Ian Munsie - Long overdue cleanup of the way we handle relocation of our open firmware trampoline (prom_init.c) on 64-bit by Anton Blanchard - Support for saving/restoring & context switching the PPR (Processor Priority Register) on server processors that support it. This allows the kernel to preserve thread priorities established by userspace. By Haren Myneni. - DAWR (new watchpoint facility) support on Power8 by Michael Neuling - Ability to change the DSCR (Data Stream Control Register) which controls cache prefetching on a running process via ptrace by Alexey Kardashevskiy - Support for context switching the TAR register on Power8 (new branch target register meant to be used by some new specific userspace perf event interrupt facility which is yet to be enabled) by Ian Munsie. - Improve preservation of the CFAR register (which captures the origin of a branch) on various exception conditions by Paulus. - Move the Bestcomm DMA driver from arch powerpc to drivers/dma where it belongs by Philippe De Muyter - Support for Transactional Memory on Power8 by Michael Neuling (based on original work by Matt Evans). For those curious about the feature, the patch contains a pretty good description."

crypto: crc32 - add crc32 pclmulqdq implementation and wrappers for table implementation

2013-01-19T23:16:45+00:00

This patch adds crc32 algorithms to shash crypto api. One is wrapper to gerneric crc32_le function. Second is crc32 pclmulqdq implementation. It use hardware provided PCLMULQDQ instruction to accelerate the CRC32 disposal. This instruction present from Intel Westmere and AMD Bulldozer CPUs. For intel core i5 I got 450MB/s for table implementation and 2100MB/s for pclmulqdq implementation. Signed-off-by: Alexander Boyko Signed-off-by: Herbert Xu

crypto: remove depends on CONFIG_EXPERIMENTAL

2013-01-11T19:38:05+00:00

powerpc: Add a powerpc implementation of SHA-1

2013-01-10T03:43:45+00:00

This patch adds a crypto driver which provides a powerpc accelerated implementation of SHA-1, accelerated in that it is written in asm. Original patch by Paul, minor fixups for upstream by moi. Lightly tested on 64-bit with the test program here: http://michael.ellerman.id.au/files/junkcode/sha1test.c Seems to work, and is "not slower" than the generic version. Needs testing on 32-bit.

crypto: camellia - add AES-NI/AVX/x86_64 assembler implementation of camellia cipher

2012-11-09T09:32:32+00:00

This patch adds AES-NI/AVX/x86_64 assembler implementation of Camellia block cipher. Implementation process data in sixteen block chunks, which are byte-sliced and AES SubBytes is reused for Camellia s-box with help of pre- and post-filtering.

crypto: crc32c - Optimize CRC32C calculation with PCLMULQDQ instruction

2012-10-15T14:18:24+00:00

This patch adds the crc_pcl function that calculates CRC32C checksum using the PCLMULQDQ instruction on processors that support this feature. This will provide speedup over using CRC32 instruction only. The usage of PCLMULQDQ necessitate the invocation of kernel_fpu_begin and kernel_fpu_end and incur some overhead. So the new crc_pcl function is only invoked for buffer size of 512 bytes or more. Larger sized buffers will expect to see greater speedup. This feature is best used coupled with eager_fpu which reduces the kernel_fpu_begin/end overhead. For buffer size of 1K the speedup is around 1.6x and for buffer size greater than 4K, the speedup is around 3x compared to original implementation in crc32c-intel module. Test was performed on Sandy Bridge based platform with constant frequency set for cpu. A white paper detailing the algorithm can be found here: http://download.intel.com/design/intarch/papers/323405.pdf Signed-off-by: Tim Chen Signed-off-by: Herbert Xu

KEYS: Implement asymmetric key type

2012-10-08T03:20:12+00:00

Create a key type that can be used to represent an asymmetric key type for use in appropriate cryptographic operations, such as encryption, decryption, signature generation and signature verification. The key type is "asymmetric" and can provide access to a variety of cryptographic algorithms. Possibly, this would be better as "public_key" - but that has the disadvantage that "public key" is an overloaded term. Signed-off-by: David Howells Signed-off-by: Rusty Russell
