| | | | | | | | | | | Pass a full set of flags to drivers' per-operation 'prep' routines. Currently the only flag passed is DMA_PREP_INTERRUPT.

* async_tx: kill tx_set_src and tx_set_dest methodsDan Williams2008-02-063-58/+83
| | | | | | | | | | | | | | | | | | | | | | The tx_set_src and tx_set_dest methods were originally implemented to allow an array of addresses to be passed down from async_xor to the dmaengine driver while minimizing stack overhead. Removing these methods allows drivers to have all transaction parameters available at 'prep' time, saves two function pointers in struct dma_async_tx_descriptor, and reduces the number of indirect branches.. A consequence of moving this data to the 'prep' routine is that multi-source routines like async_xor need temporary storage to convert an array of linear addresses into an array of dma addresses. In order to keep the same stack footprint of the previous implementation the input array is reused as storage for the dma addresses. This requires that sizeof(dma_addr_t) be less than or equal to sizeof(void *). As a consequence CONFIG_DMADEVICES now depends on !CONFIG_HIGHMEM64G. It also requires that drivers be able to make descriptor resources available when the 'prep' routine is polled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes chainiv avoid spinning by postponing requests on lock contention if the user allows the use of asynchronous algorithms. If a synchronous algorithm is requested then we behave as before. This should improve IPsec performance on SMP when two CPUs attempt to transmit over the same SA. Currently one of them will spin doing nothing waiting for the other CPU to finish its encryption. This patch makes it postpone the request and get on with other work. If only one CPU is transmitting for a given SA, then we will process the request synchronously as before. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| * [CRYPTO] aead: Allow algorithms with no givcrypt supportHerbert Xu2008-01-111-3/+3
| | | | | | | | | | | | | | | | | | Some algorithms always require manual IV construction. For instance, the generic CCM algorithm requires the first byte of the IV to be manually constructed.

| * [CRYPTO] aead: Add givcrypt operationsHerbert Xu2008-01-111-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the underlying givcrypt operations for aead and associated support elements. The rationale is identical to that of the skcipher givcrypt operations, i.e., sometimes only the algorithm knows how the IV should be generated. A new request type aead_givcrypt_request is added which contains an embedded aead_request structure with two new elements to support this operation. The new elements are seq and giv. The seq field should contain a strictly increasing 64-bit integer which may be used by certain IV generators as an input value. The giv field will be used to store the generated IV. It does not need to obey the alignment requirements of the algorithm because it's not used during the operation. The existing iv field must still be available as it will be used to store intermediate IVs and the output IV if chaining is desired. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * [CRYPTO] seqiv: Add Sequence Number IV GeneratorHerbert Xu2008-01-114-0/+198

| | | | | | | | | | | | | | | | | | | | | | This patch adds the gcm_base template which takes a block cipher parameter instead of cipher.

| * [CRYPTO] skcipher: Create default givcipher instancesHerbert Xu2008-01-114-6/+177
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes crypto_alloc_ablkcipher/crypto_grab_skcipher always return algorithms that are capable of generating their own IVs through givencrypt and givdecrypt. Each algorithm may specify its default IV generator through the geniv field. For algorithms that do not set the geniv field, the blkcipher layer will pick a default. Currently it's chainiv for synchronous algorithms and eseqiv for asynchronous algorithms. Note that if these wrappers do not work on an algorithm then that algorithm must specify its own geniv or it can't be used at all. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * [CRYPTO] eseqiv: Add Encrypted Sequence Number IV GeneratorHerbert Xu2008-01-112-0/+265
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This generator generates an IV based on a sequence number by xoring it with a salt and then encrypting it with the same key as used to encrypt the plain text. This algorithm requires that the block size be equal to the IV size. It is mainly useful for CBC. It has one noteworthy property that for IPsec the IV happens to lie just before the plain text so the IV generation simply increases the number of encrypted blocks by one. Therefore the cost of this generator is entirely dependent on the speed of the underlying cipher. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * [CRYPTO] chainiv: Add chain IV generatorHerbert Xu2008-01-112-0/+140
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The chain IV generator is the one we've been using in the IPsec stack. It simply starts out with a random IV, then uses the last block of each encrypted packet's cipher text as the IV for the next packet. It can only be used by synchronous ciphers since we have to make sure that we don't start the encryption of the next packet until the last one has completed. It does have the advantage of using very little CPU time since it doesn't have to generate anything at all. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | This patch introduces the geniv field which indicates the default IV generator for each algorithm. It should point to a string that is not freed as long as the algorithm is registered. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * [CRYPTO] skcipher: Add givcrypt operations and givcipher typeHerbert Xu2008-01-111-0/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Different block cipher modes have different requirements for intialisation vectors. For example, CBC can use a simple randomly generated IV while modes such as CTR must use an IV generation mechanisms that give a stronger guarantee on the lack of collisions. Furthermore, disk encryption modes have their own IV generation algorithms. Up until now IV generation has been left to the users of the symmetric key cipher API. This is inconvenient as the number of block cipher modes increase because the user needs to be aware of which mode is supposed to be paired with which IV generation algorithm. Therefore it makes sense to integrate the IV generation into the crypto API. This patch takes the first step in that direction by creating two new ablkcipher operations, givencrypt and givdecrypt that generates an IV before performing the actual encryption or decryption. The operations are currently not exposed to the user. That will be done once the underlying functionality has actually been implemented. It also creates the underlying givcipher type. Algorithms that directly generate IVs would use it instead of ablkcipher. All other algorithms (including all existing ones) would generate a givcipher algorithm upon registration. This givcipher algorithm will be constructed from the geniv string that's stored in every algorithm. That string will locate a template which is instantiated by the blkcipher/ablkcipher algorithm in question to give a givcipher algorithm. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * [CRYPTO] skcipher: Add crypto_grab_skcipher interfaceHerbert Xu2008-01-111-2/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Note: From now on the collective of ablkcipher/blkcipher/givcipher will be known as skcipher, i.e., symmetric key cipher. The name blkcipher has always been much of a misnomer since it supports stream ciphers too. This patch adds the function crypto_grab_skcipher as a new way of getting an ablkcipher spawn. The problem is that previously we did this in two steps, first getting the algorithm and then calling crypto_init_spawn. This meant that each spawn user had to be aware of what type and mask to use for these two steps. This is difficult and also presents a problem when the type/mask changes as they're about to be for IV generators. The new interface does both steps together just like crypto_alloc_ablkcipher. As a side-effect this also allows us to be stronger on type enforcement for spawns. For now this is only done for ablkcipher but it's trivial to extend for other types. This patch also moves the type/mask logic for skcipher into the helpers crypto_skcipher_type and crypto_skcipher_mask. Finally this patch introduces the function crypto_require_sync to determine whether the user is specifically requesting a sync algorithm. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | As discussed previously, this patch moves the basic CTR functionality into a chainable algorithm called ctr. The IPsec-specific variant of it is now placed on top with the name rfc3686. So ctr(aes) gives a chainable cipher with IV size 16 while the IPsec variant will be called rfc3686(ctr(aes)). This patch also adjusts gcm accordingly. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * [CRYPTO] blkcipher: Merge ablkcipher and blkcipher into one option/moduleHerbert Xu2008-01-112-7/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | With the impending addition of the givcipher type, both blkcipher and ablkcipher algorithms will use it to create givcipher objects. As such it no longer makes sense to split the system between ablkcipher and blkcipher. In particular, both ablkcipher.c and blkcipher.c would need to use the givcipher type which has to reside in ablkcipher.c since it shares much code with it.
