* crypto: mv_cesa - Add support for Orion5X crypto engineSebastian Andrzej Siewior2009-08-104-0/+739
| | | | | | | | | | This adds support for Marvell's Cryptographic Engines and Security Accelerator (CESA) which can be found on a few SoC. Tested with dm-crypt. Acked-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Sebastian Andrzej Siewior <sebastian@breakpoint.cc> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: cryptd - Add support to access underlaying shashHuang Ying2009-08-062-0/+52
| | | | | | | | | cryptd_alloc_ahash() will allocate a cryptd-ed ahash for specified algorithm name. The new allocated one is guaranteed to be cryptd-ed ahash, so the shash underlying can be gotten via cryptd_ahash_child().

* crypto: gcm - Use GHASH digest algorithmHuang Ying2009-08-062-174/+408
| | | | | | | | | | | | Remove the dedicated GHASH implementation in GCM, and uses the GHASH digest algorithm instead. This will make GCM uses hardware accelerated GHASH implementation automatically if available. ahash instead of shash interface is used, because some hardware accelerated GHASH implementation needs asynchronous interface.

* crypto: ghash - Add GHASH digest algorithm for GCMHuang Ying2009-08-063-0/+178
| | | | | | | | | GHASH is implemented as a shash algorithm. The actual implementation is copied from gcm.c. This makes it possible to add architecture/hardware accelerated GHASH implementation. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: authenc - Convert to ahashSteffen Klassert2009-08-051-69/+285
| | | | | | | This patch converts authenc to the new ahash interface. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: api - Fix aligned ctx helperHerbert Xu2009-07-241-6/+2
| | | | | | | | | | | | | The aligned ctx helper was using a bogus alignment value thas was one off the correct value. Fortunately the current users do not require anything beyond the natural alignment of the platform so this hasn't caused a problem. This patch fixes that and also removes the unnecessary minimum check since if the alignment is less than the natural alignment then the subsequent ALIGN operation should be a noop.

* crypto: hmac - Prehash ipad/opadHerbert Xu2009-07-241-46/+62
| | | | | | | | This patch uses crypto_shash_export/crypto_shash_import to prehash ipad/opad to speed up hmac. This is partly based on a similar patch by Steffen Klassert. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: aes - Undefined behaviour in crypto_aes_expand_keyPhil Carmody2009-07-241-2/+7
| | | | | | | | | | | | | | | It's undefined behaviour in C to write outside the bounds of an array. The key expansion routine takes a shortcut of creating 8 words at a time, but this creates 4 additional words which don't fit in the array. As everyone is hopefully now aware, GCC is at liberty to make any assumptions and optimisations it likes in situations where it can detect that UB has occured, up to and including nasal demons, and as the indices being accessed in the array are trivially calculable, it's rash to invite gcc to do take any liberties at all.

* crypto: shash - Test for the algorithms import function before exporting itSteffen Klassert2009-07-241-1/+1
| | | | | | | | | crypto_init_shash_ops_async() tests for setkey and not for import before exporting the algorithms import function to ahash. This patch fixes this. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: ahash - Use GFP_KERNEL on allocation if the request can sleepSteffen Klassert2009-07-241-2/+2
| | | | | | | | | ahash_op_unaligned() and ahash_def_finup() allocate memory atomically, regardless whether the request can sleep or not. This patch changes this to use GFP_KERNEL if the request can sleep. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: shash - Require all algorithms to support export/importHerbert Xu2009-07-221-8/+11
| | | | | | | | | | | | | | | | | This patch provides a default export/import function for all shash algorithms. It simply copies the descriptor context as is done by sha1_generic. This in essence means that all existing shash algorithms now support export/import. This is something that will be depended upon in implementations such as hmac. Therefore all new shash and ahash implementations must support export/import. For those that cannot obtain a partial result, padlock-sha's fallback model should be used so that a partial result is always available. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: sha512-s390 - Add export/import supportHerbert Xu2009-07-221-0/+36
| | | | | | | | | | | This patch adds export/import support to sha512-s390 (which includes sha384-s390). The exported type is defined by struct sha512_state, which is basically the entire descriptor state of sha512_generic. Since sha512-s390 only supports a 64-bit byte count the import function will reject anything that exceeds that. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: sha512_generic - Use 64-bit countersHerbert Xu2009-07-222-20/+14
| | | | | | | | This patch replaces the 32-bit counters in sha512_generic with 64-bit counters. It also switches the bit count to the simpler byte count. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: sha512 - Export struct sha512_stateHerbert Xu2009-07-222-13/+13
| | | | | | | | This patch renames struct sha512_ctx and exports it as struct sha512_state so that other sha512 implementations can use it as the reference structure for exporting their state. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: xcbc - Fix shash conversionHerbert Xu2009-07-221-91/+73
| | | | | | | | | | | Although xcbc was converted to shash, it didn't obey the new requirement that all hash state must be stored in the descriptor rather than the transform. This patch fixes this issue and also optimises away the rekeying by precomputing K2 and K3 within setkey. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: xcbc - Use crypto_xorHerbert Xu2009-07-221-16/+6
| | | | | | | This patch replaces the local xor function with the generic crypto_xor function. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: cryptd - Add finup/export/import for hashHerbert Xu2009-07-221-0/+40
| | | | | | | | This patch adds the finup/export/import functions to the cryptd ahash implementation. We simply invoke the underlying shash operations. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: s390 - Fix sha build failureSachin Sant2009-07-162-2/+2
| | | | | | | | Use struct s390_sha_ctx instead of sha1/sha256_state struct to fix s390 crypto build break. Signed-off-by: Sachin Sant <sachinp@in.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: padlock - Fix hashing of partial blocksHerbert Xu2009-07-161-0/+2
| | | | | | | | When we encounter partial blocks in finup, we'll invoke the xsha instruction with a bogus count that is not a multiple of the block size. This patch fixes it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: shash - Fix async finup handling of null digestHerbert Xu2009-07-151-2/+7
| | | | | | | When shash_ahash_finup encounters a null request, we end up not calling the underlying final function. This patch fixes that. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: shash - Fix digest size offsetHerbert Xu2009-07-151-1/+2
| | | | | | | | | | | When an shash algorithm is exported as ahash, ahash will access its digest size through hash_alg_common. That's why the shash layout needs to match hash_alg_common. This wasn't the case because the alignment weren't identical. This patch fixes the problem. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: ahash - Fix setkey crashHerbert Xu2009-07-151-4/+2
| | | | | | | | | | When the alignment check was made unconditional for ahash we may end up crashing on shash algorithms because we're always calling alg->setkey instead of tfm->setkey. This patch fixes it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: padlock - Fix compile error on i386Herbert Xu2009-07-151-2/+4
| | | | | | | | | | The previous change to allow hashing from states other than the initial broke compilation on i386 because the inline assembly tried to squeeze a u64 into a 32-bit register. As we've already checked for 32-bit overflows we can simply truncate it to u32, or unsigned long so that we don't truncate at all on x86-64. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: xcbc - Fix incorrect error value when creating instanceHerbert Xu2009-07-151-0/+1
| | | | | | | If shash_alloc_instance() fails, we return the wrong error value. This patch fixes it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: hmac - Fix incorrect error value when creating instanceHerbert Xu2009-07-151-0/+1
| | | | | | | If shash_alloc_instance() fails, we return the wrong error value. This patch fixes it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: cryptd - Fix uninitialized return valueSteffen Klassert2009-07-151-0/+2
| | | | | | | | If cryptd_alloc_instance() fails, the return value is uninitialized. This patch fixes this by setting the return value. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: crypto4xx - Disable SHA implementationHerbert Xu2009-07-151-19/+0
| | | | | | | | | | The crypto4xx SHA implementation keeps the hash state in the tfm data structure. This breaks a fundamental requirement of ahash implementations that they must be reentrant. This patch disables the broken implementation. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: ahash - Add unaligned handling and default operationsHerbert Xu2009-07-154-22/+263
| | | | | | | | | | This patch exports the finup operation where available and adds a default finup operation for ahash. The operations final, finup and digest also will now deal with unaligned result pointers by copying it. Finally export/import operations are will now be exported too. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: ahash - Use GFP_KERNEL in unaligned setkeyHerbert Xu2009-07-141-1/+1
| | | | | | | | We currently use GFP_ATOMIC in the unaligned setkey function to allocate the temporary aligned buffer. Since setkey must be called in a sleepable context, we can use GFP_KERNEL instead. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: shash - Fix alignment in unaligned operationsHerbert Xu2009-07-141-2/+4
| | | | | | | | When we encounter an unaligned pointer we are supposed to copy it to a temporary aligned location. However the temporary buffer isn't aligned properly. This patch fixes that. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: hash - Zap unaligned buffersHerbert Xu2009-07-142-5/+12
| | | | | | | | | | | | Some unaligned buffers on the stack weren't zapped properly which may cause secret data to be leaked. This patch fixes them by doing a zero memset. It is also possible for us to place random kernel stack contents in the digest buffer if a digest operation fails. This is fixed by only copying if the operation succeeded. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: ahash - Remove old_ahash_algHerbert Xu2009-07-145-53/+1
| | | | | | | Now that all ahash implementations have been converted to the new ahash type, we can remove old_ahash_alg and its associated support. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: crypto4xx - Switch to new style ahashHerbert Xu2009-07-143-39/+77
| | | | | | | | | | | | This patch changes crypto4xx to use the new style ahash type. In particular, we now use ahash_alg to define ahash algorithms instead of crypto_alg. This is achieved by introducing a union that encapsulates the new type and the existing crypto_alg structure. They're told apart through a u32 field containing the type value. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: cryptd - Switch to new style ahashHerbert Xu2009-07-141-27/+37
| | | | | | | | This patch changes cryptd to use the new style ahash type. In particular, the instance is enlarged to encapsulate the new ahash_alg structure. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: cryptd - Switch to template create APIHerbert Xu2009-07-143-27/+32
| | | | | | | | This patch changes cryptd to use the template->create function instead of alloc in anticipation for the switch to new style ahash algorithms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: hash - Add helpers to free spawnsHerbert Xu2009-07-141-0/+10
| | | | | | | This patch adds the helpers crypto_drop_ahash and crypto_drop_shash so that these spawns can be dropped without ugly casts. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: tcrypt - Add mask parameterHerbert Xu2009-07-141-3/+6
| | | | | | | | This patch adds a mask parameter to complement the existing type parameter. This is useful when instantiating algorithms that require a mask other than the default, e.g., ahash algorithms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: ahash - Add instance/spawn supportHerbert Xu2009-07-142-0/+123
| | | | | | | This patch adds support for creating ahash instances and using ahash as spawns. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: ahash - Convert to new style algorithmsHerbert Xu2009-07-145-91/+148
| | | | | | | | | This patch converts crypto_ahash to the new style. The old ahash algorithm type is retained until the existing ahash implementations are also converted. All ahash users will automatically get the new crypto_ahash type. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: api - Remove frontend argument from extsize/init_tfmHerbert Xu2009-07-144-14/+8
| | | | | | | As the extsize and init_tfm functions belong to the frontend the frontend argument is superfluous. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: crypto4xx - Use crypto_ahash_set_reqsizeHerbert Xu2009-07-142-2/+4
| | | | | | | This patch makes crypto4xx use crypto_ahash_set_reqsize to avoid accessing crypto_ahash directly. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: cryptd - Use crypto_ahash_set_reqsizeHerbert Xu2009-07-141-2/+3
| | | | | | | This patch makes cryptd use crypto_ahash_set_reqsize to avoid accessing crypto_ahash directly. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: ahash - Add crypto_ahash_set_reqsizeHerbert Xu2009-07-141-0/+6
| | | | | | | This patch adds the helper crypto_ahash_set_reqsize so that implementations do not directly access the crypto_ahash structure. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: cryptd - Use shash algorithmsHerbert Xu2009-07-141-80/+84
| | | | | | | This patch changes cryptd to use shash algorithms instead of the legacy hash interface. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: shash - Export async functionsHerbert Xu2009-07-142-20/+25
| | | | | | | This patch exports the async functions so that they can be reused by cryptd when it switches over to using shash. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: hash - Remove legacy hash/digest implementaionHerbert Xu2009-07-143-34/+3
| | | | | | | | This patch removes the implementation of hash and digest now that no algorithms use them anymore. The interface though will remain until the users are converted across. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: authenc - Remove reference to crypto_hashHerbert Xu2009-07-141-5/+1
| | | | | | | Now that there are no more legacy hash implementations we can remove the reference to crypto_hash. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: xcbc - Switch to shashHerbert Xu2009-07-141-148/+87
| | | | | | This patch converts the xcbc algorithm to the new shash type. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: hmac - Switch to shashHerbert Xu2009-07-141-157/+114
| | | | | | This patch changes hmac to the new shash interface. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: padlock - Switch sha to shashHerbert Xu2009-07-142-179/+156
| | | | | | | | | | | | | | | | | | | This patch converts the padlock-sha implementation to shash. In doing so the existing mechanism of storing the data until final is no longer viable as we do not have a way of allocating data in crypto_shash_init and then reliably freeing it. This is just as well because a better way of handling the problem is to hash everything but the last chunk using normal sha code and then provide the intermediate result to the padlock device. This is good enough because the primary application of padlock-sha is IPsec and there the data is laid out in the form of an hmac header followed by the rest of the packet. In essence we can provide all the data to the padlock as the hmac header only needs to be hashed once. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
