| | | | | | | | | | | This patch fixes the multi-page processing bug that affects large test vectors (the same bug that previously affected ctr.c). There is an optimization for the case walk.nbytes == nbytes. Also we now use crypto_xor() instead of adhoc XOR routines.

* [CRYPTO] gcm: Put abreq in private context instead of on stackHerbert Xu2008-01-111-7/+11
| | | | | | | | | The abreq structure is currently allocated on the stack. This is broken if the underlying algorithm is asynchronous. This patch changes it so that it's taken from the private context instead which has been enlarged accordingly. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] scatterwalk: Restore custom sg chaining for nowHerbert Xu2008-01-115-5/+17
| | | | | | | | Unfortunately the generic chaining hasn't been ported to all architectures yet, and notably not s390. So this patch restores the chainging that we've been using previously which does work everywhere. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] scatterwalk: Move scatterwalk.h to linux/cryptoHerbert Xu2008-01-118-41/+42
| | | | | | | | The scatterwalk infrastructure is used by algorithms so it needs to move out of crypto for future users that may live in drivers/crypto or asm/*/crypto. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] aead: Return EBADMSG for ICV mismatchHerbert Xu2008-01-112-2/+2
| | | | | | | This patch changes gcm/authenc to return EBADMSG instead of EINVAL for ICV mismatches. This convention has already been adopted by IPsec. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] gcm: Fix ICV handlingHerbert Xu2008-01-113-129/+113
| | | | | | | | | | | | | The crypto_aead convention for ICVs is to include it directly in the output. If we decided to change this in future then we would make the ICV (if the algorithm has an explicit one) available in the request itself. For now no algorithm needs this so this patch changes gcm to conform to this convention. It also adjusts the tcrypt aead tests to take this into account.

* [CRYPTO] tcrypt: Make gcm available as a standalone testHerbert Xu2008-01-111-0/+7
| | | | | | | Currently the gcm(aes) tests have to be taken together with all other ciphers. This patch makes it available by itself at number 35. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] authenc: Fix hash verificationHerbert Xu2008-01-111-4/+10
| | | | | | | | | | The previous code incorrectly included the hash in the verification which also meant that we'd crash and burn when it comes to actually verifying the hash since we'd go past the end of the SG list. This patch fixes that by subtracting authsize from cryptlen at the start. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] authenc: Move enckeylen into key itselfHerbert Xu2008-01-112-20/+56
| | | | | | | | | | | | | | | Having enckeylen as a template parameter makes it a pain for hardware devices that implement ciphers with many key sizes since each one would have to be registered separately. Since the authenc algorithm is mainly used for legacy purposes where its key is going to be constructed out of two separate keys, we can in fact embed this value into the key itself. This patch does this by prepending an rtnetlink header to the key that contains the encryption key length. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] aead: Make authsize a run-time parameterHerbert Xu2008-01-114-32/+38
| | | | | | | | | | | | | | | As it is authsize is an algorithm paramter which cannot be changed at run-time. This is inconvenient because hardware that implements such algorithms would have to register each authsize that they support separately. Since authsize is a property common to all AEAD algorithms, we can add a function setauthsize that sets it at run-time, just like setkey. This patch does exactly that and also changes authenc so that authsize is no longer a parameter of its template. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] authenc: Use or instead of max on alignment masksHerbert Xu2008-01-111-1/+1

* [CRYPTO] tcrypt: AES CTR large test vectorTan Swee Heng2008-01-111-3/+1048
| | | | | | | | | | | | This patch adds a large AES CTR mode test vector. The test vector is 4100 bytes in size. It was generated using a C++ program that called Crypto++.

| | | | | | | | | | Currently the number of entries in a cipher test vector template is limited by TVMEMSIZE/sizeof(struct cipher_testvec).

* [CRYPTO] ctr: Fix multi-page processingHerbert Xu2008-01-111-31/+33
| | | | | | | | | | | | | | | | | | | When the data spans across a page boundary, CTR may incorrectly process a partial block in the middle because the blkcipher walking code may supply partial blocks in the middle as long as the total length of the supplied data is more than a block. CTR is supposed to return any unused partial block in that case to the walker. This patch fixes this by doing exactly that, returning partial blocks to the walker unless we received less than a block-worth of data to start with. This also allows us to optimise the bulk of the processing since we no longer have to worry about partial blocks until the very end. Thanks to Tan Swee Heng for fixes and actually testing this :) Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* [CRYPTO] pcbc: Use crypto_xorHerbert Xu2008-01-111-81/+24
| | | | | | | | | This patch replaces the custom xor in CBC with the generic crypto_xor. It changes the operations for in-place encryption slightly to avoid calling crypto_xor with tmpbuf since it is not necessarily aligned. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] cbc: Require block size to be a power of 2Herbert Xu2008-01-111-8/+10
| | | | | | | | | | | | | | All common block ciphers have a block size that's a power of 2. In fact, all of our block ciphers obey this rule. If we require this then CBC can be optimised to avoid an expensive divide on in-place decryption. I've also changed the saving of the first IV in the in-place decryption case to the last IV because that lets us use walk->iv (which is already aligned) for the xor operation where alignment is required.

| | | | | | | | | | | | With the addition of more stream ciphers we need to curb the proliferation of ad-hoc xor functions. This patch creates a generic pair of functions, crypto_inc and crypto_xor which does big-endian increment and exclusive or, respectively. For optimum performance, they both use u32 operations so alignment must be as that of u32 even though the arguments are of type u8 *. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* [HIFN]: Improve PLL initializationPatrick McHardy2008-01-111-2/+108
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 Xu2008-01-116-20/+19
| | | | | | | | | | | | | | | | | | | | | | | | 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>
