* crypto: ixp4xx - Hardware crypto support for IXP4xx CPUsChristian Hohnstaedt2008-07-10
| | | | | | | | | | | Add support for the hardware crypto engine provided by the NPE C of the Intel IXP4xx networking processor series. Supported ciphers: des, des3, aes and a combination of them with md5 and sha1 hmac Signed-off-by: Christian Hohnstaedt <chohnstaedt@innominate.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | Add support for the SEC available on a wide range of PowerQUICC devices, e.g. MPC8349E, MPC8548E. This initial version supports authenc(hmac(sha1),cbc(aes)) for use with IPsec.

* [CRYPTO] tcrypt: Add self test for des3_ebe cipher operating in cbc modeNeil Horman2008-07-10
| | | | | | | | | | | | | | | | | | Patch to add checking of DES3 test vectors using CBC mode. FIPS-140-2 compliance mandates that any supported mode of operation must include a self test. This satisfies that requirement for cbc(des3_ede). The included test vector was generated by me using openssl. Key/IV was generated with the following command: openssl enc -des_ede_cbc -P input and output values were generated by repeating the string "Too many secrets" a few times over, truncating it to 128 bytes, and encrypting it with openssl using the aformentioned key.

* [CRYPTO] rmd: Use pointer form of endian swapping operationsHerbert Xu2008-07-10
| | | | | | | | | | | | This patch converts the relevant code in the rmd implementations to use the pointer form of the endian swapping operations. This allows certain architectures to generate more optimised code. For example, on sparc64 this more than halves the CPU cycles on a typical hashing operation. Based on a patch by David Miller.

Note 1: also fix a harmless typo while moving it: sa_idx is initialized to dma->resi instead of dma->cmdi.

* [HIFN]: Use unique driver names for different algosPatrick McHardy2008-07-10
| | | | | | | | | | | | | When the CryptoAPI instantiates a new algorithm, it performs a lookup by driver name.

| | | | | | | | | | | | | | | The check for misalignment of the scatterlist data has two bugs: - the source buffer doesn't need to be aligned at all - the destination buffer and its size needs to be aligned to a multiple of 4, not to the crypto alg blocksize Introduce symbolic constant for destination buffer alignment requirements, use it instead of the crypto alg blocksize and remove the unnecessary checks for source buffer alignment and change cra_alignmask to zero.
