According to the Herbert Xu, client may not always call crypto_ahash_final(). In the case of error in hash calculation resources will be automatically cleaned up. But if no hash calculation error happens and client will not call crypto_ahash_final() at all, then internal buffer will not be freed, and clocks will not be disabled. This patch provides support for atomic crypto_ahash_update() call. Clocks are now enabled and disabled per update request. Data buffer is now allocated as a part of request context. Client is obligated to free it with crypto_free_ahash(). Signed-off-by: Dmitry Kasatkin <dmitry.kasatkin@nokia.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Introduces DMA error handling. DMA error is returned as a result code of the hash request. Clients needs to handle error codes and may repeat hash calculation attempt. Also in the case of DMA error, SHAM module is set to be re-initialized again. It significantly improves stability against possible HW failures.

DMA parameters for constant data were initialized during driver probe(). It seems that those settings sometimes are lost when devices goes to off mode.

The AES-NI instructions are also available in legacy mode so the 32-bit architecture may profit from those, too. To illustrate the performance gain here's a short summary of a dm-crypt speed test on a Core i7 M620 running at 2.67GHz comparing both assembler implementations: x86: i568 aes-ni delta ECB, 256 bit: 93.8 MB/s 123.3 MB/s +31.4% CBC, 256 bit: 84.8 MB/s 262.3 MB/s +209.3% LRW, 256 bit: 108.6 MB/s 222.1 MB/s +104.5% XTS, 256 bit: 105.0 MB/s 205.5 MB/s +95.7% Additionally, due to some minor optimizations, the 64-bit version also got a minor performance gain as seen below: x86-64: old impl. new impl. delta ECB, 256 bit: 121.1 MB/s 123.0 MB/s +1.5% CBC, 256 bit: 285.3 MB/s 290.8 MB/s +1.9% LRW, 256 bit: 263.7 MB/s 265.3 MB/s +0.6% XTS, 256 bit: 251.1 MB/s 255.3 MB/s +1.7% Signed-off-by: Mathias Krause <minipli@googlemail.com> Reviewed-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

This patch adds the af_alg plugin for symmetric key ciphers, corresponding to the ablkcipher kernel operation type. Keys can optionally be set through the setsockopt interface. Once a sendmsg call occurs without MSG_MORE no further writes may be made to the socket until all previous data has been read. IVs and and whether encryption/decryption is performed can be set through the setsockopt interface or as a control message to sendmsg. The interface is completely synchronous, all operations are carried out in recvmsg(2) and will complete prior to the system call returning. The splice(2) interface support reading the user-space data directly without copying (except that the Crypto API itself may copy the data if alignment is off). The recvmsg(2) interface supports directly writing to user-space without additional copying, i.e., the kernel crypto interface will receive the user-space address as its output SG list. Thakns to Miloslav Trmac for reviewing this and contributing fixes and improvements. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Acked-by: David S. Miller <davem@davemloft.net>

This patch adds the af_alg plugin for hash, corresponding to the ahash kernel operation type. Keys can optionally be set through the setsockopt interface. Each sendmsg call will finalise the hash unless sent with a MSG_MORE flag. Partial hash states can be cloned using accept(2). The interface is completely synchronous, all operations will complete prior to the system call returning. Both sendmsg(2) and splice(2) support reading the user-space data directly without copying (except that the Crypto API itself may copy the data if alignment is off). For now only the splice(2) interface supports performing digest instead of init/update/final. In future the sendmsg(2) interface will also be modified to use digest/finup where possible so that hardware that cannot return a partial hash state can still benefit from this interface.

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.

This patch adds an optimized RFC4106 AES-GCM implementation for 64-bit kernels. It supports 128-bit AES key size. This leverages the crypto AEAD interface type to facilitate a combined AES & GCM operation to be implemented in assembly code. The assembly code leverages Intel(R) AES New Instructions and the PCLMULQDQ instruction.

I noticed that by factoring out common rounds from the branches of the if-statements in the encryption and decryption functions, the executable file size goes down significantly, for crypto/cast5.ko from 26688 bytes to 24336 bytes (amd64). On my test system, I saw a slight speedup. This is the first time I'm doing such a benchmark - I found a similar one on the crypto mailing list, and I hope I did it right?

Surprisingly chown() on ext4 is not SMP scalable operation. Due to unconditional orphan_del(NULL, inode) in ext4_setattr() result in significant performance overhead because of global orphan mutex, especially in no-journal mode (where orphan_add() is noop). It is possible to skip explicit orphan_del if possible.
