* crypto: serpent-sse2 - add lrw supportJussi Kivilinna2011-11-211-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch adds LRW support for serpent-sse2 by using lrw_crypt(). Patch has been tested with tcrypt and automated filesystem tests.

* crypto: Unlink and free instances when deletedSteffen Klassert2011-11-091-0/+1
| | | | | | | | | | We leak the crypto instance when we unregister an instance with crypto_del_alg(). Therefore we introduce crypto_unregister_instance() to unlink the crypto instance from the template's instances list and to free the recources of the instance properly.

* net: remove mm.h inclusion from netdevice.hAlexey Dobriyan2011-06-221-0/+1
| | | | | | | | | | | | | | | | | Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually). To prevent mm.h inclusion via other channels also extract "enum dma_data_direction" definition into separate header. This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file. Note, that mm_types.h is still dragged in, but it is a separate story. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* crypto: af_alg - User-space interface for Crypto APIHerbert Xu2010-11-191-0/+92
| | | | | | | | | | | | | | | | | | | | | | | | | This patch creates the backbone of the user-space interface for the Crypto API, through a new socket family AF_ALG. Each session corresponds to one or more connections obtained from that socket. The number depends on the number of inputs/outputs of that particular type of operation. For most types there will be a s ingle connection/file descriptor that is used for both input and output. AEAD is one of the few that require two inputs. Each algorithm type will provide its own implementation that plugs into af_alg. They're keyed using a string such as "skcipher" or "hash". IOW this patch only contains the boring bits that is required to hold everything together. Thakns to Miloslav Trmac for reviewing this and contributing fixes and improvements.

* crypto: skcipher - Add ablkcipher_walk interfacesDavid S. Miller2010-05-191-0/+40
| | | | | | | | | | | | | | | | | | | | | | These are akin to the blkcipher_walk helpers. The main differences in the async variant are: 1) Only physical walking is supported. We can't hold on to kmap mappings across the async operation to support virtual ablkcipher_walk operations anyways. 2) Bounce buffers used for async more need to be persistent and freed at a later point in time when the async op completes. Therefore we maintain a list of writeback buffers and require that the ablkcipher_walk user call the 'complete' operation so we can copy the bounce buffers out to the real buffers and free up the bounce buffer chunks. These interfaces will be used by the new Niagara2 crypto driver. Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

More information about PCLMULQDQ can be found at: http://software.intel.com/en-us/articles/carry-less-multiplication-and-its-usage-for-computing-the-gcm-mode/ Because PCLMULQDQ changes XMM state, its usage must be enclosed with kernel_fpu_begin/end, which can be used only in process context, the acceleration is implemented as crypto_ahash.
