* crypto: ixp4xx - Select CRYPTO_AUTHENCImre Kaloz2008-07-13
| | | | | | | | | Without CRYPTO_AUTHENC the driver fails to build: drivers/built-in.o: In function `ixp_module_init': ixp4xx_crypto.c:(.init.text+0x3250): undefined reference to `crypto_aead_type' Signed-off-by: Imre Kaloz <kaloz@openwrt.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: talitos - Add support for sha256 and md5 variantsLee Nipper2008-07-10
| | | | | | | | | | | | This patch adds support for: authenc(hmac(sha256),cbc(aes)), authenc(hmac(sha256),cbc(des3_ede)), authenc(hmac(md5),cbc(aes)), authenc(hmac(md5),cbc(des3_ede)). Some constant usage was changed to use aes, des, and sha include files. Signed-off-by: Lee Nipper <lee.nipper@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: talitos - Use proper form for algorithm driver namesHerbert Xu2008-07-10
| | | | | | | | | | | The name authenc(hmac(sha1-talitos),cbc(aes-talitos)) is potentially ambiguous since it could also mean using the generic authenc template on hmac(sha1-talitos) and cbc(aes-talitos). In general, parentheses should be reserved for templates that spawn algorithms. This patches changes it to the form authenc-hmac-sha1-cbc-aes-talitos.

* crypto: talitos - Add support for 3desLee Nipper2008-07-10
| | | | | | | | | | This patch adds support for authenc(hmac(sha1),cbc(des3_ede)) to the talitos crypto driver for the Freescale Security Engine. Some adjustments were made to the scatterlist to link table conversion to make 3des work for ping -s 1439..1446.

| | | | | | | | | | | | | | | | Move command descriptor setup to seperate function as preparation for the following DMA setup fixes. Note 1: also fix a harmless typo while moving it: sa_idx is initialized to dma->resi instead of dma->cmdi. Note 2: errors from command descriptor setup are not propagated back, anymore, they can't be handled anyway and all conditions leading to errors should be checked earlier.

| | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current PLL initalization has a number of deficiencies: - uses fixed multiplier of 8, which overclocks the chip when using a reference clock that operates at frequencies above 33MHz. According to a comment in the BSD source, this is true for the external clock on almost all every board. - writes to a reserved bit - doesn't follow the initialization procedure specified in chapter 6.11.1 of the HIFN hardware users guide - doesn't allow to use the PCI clock This patch adds a module parameter to specify the reference clock (pci or external) and its frequency and uses that to calculate the optimum multiplier to reach the maximal speed. By default it uses the external clock and assumes a speed of 66MHz, which effectively halfs the frequency currently used.

| * [CRYPTO] ablkcipher: Add distinct ABLKCIPHER typeHerbert Xu2008-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Up until now we have ablkcipher algorithms have been identified as type BLKCIPHER with the ASYNC bit set. This is suboptimal because ablkcipher refers to two things. On the one hand it refers to the top-level ablkcipher interface with requests. On the other hand it refers to and algorithm type underneath. As it is you cannot request a synchronous block cipher algorithm with the ablkcipher interface on top. This is a problem because we want to be able to eventually phase out the blkcipher top-level interface. This patch fixes this by making ABLKCIPHER its own type, just as we have distinct types for HASH and DIGEST. The type it associated with the algorithm implementation only. Which top-level interface is used for synchronous block ciphers is then determined by the mask that's used. If it's a specific mask then the old blkcipher interface is given, otherwise we go with the new ablkcipher interface. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
