* crypto: cbc - Convert to skcipherHerbert Xu2016-11-281-104/+138
| | | | | | | This patch converts cbc over to the skcipher interface. It also rearranges the code to allow it to be reused by drivers. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: aesni - Convert to skcipherHerbert Xu2016-11-281-4/+3
| | | | | | | | | This patch converts aesni (including fpu) over to the skcipher interface. The LRW implementation has been removed as the generic LRW code can now be used directly on top of the accelerated ECB implementation. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: testmgr - Do not test internal algorithmsHerbert Xu2016-11-282-150/+11
| | | | | | | | | | | | Currently we manually filter out internal algorithms using a list in testmgr. This is dangerous as internal algorithms cannot be safely used even by testmgr. This patch ensures that they're never processed by testmgr at all. This patch also removes an obsolete bypass for nivciphers which no longer exist.

* crypto: glue_helper - Add skcipher xts helpersHerbert Xu2016-11-281-1/+1
| | | | | | | This patch adds xts helpers that use the skcipher interface rather than blkcipher. This will be used by aesni_intel. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: simd - Add simd skcipher helperHerbert Xu2016-11-283-0/+232
| | | | | | | | | This patch adds the simd skcipher helper which is meant to be a replacement for ablk helper. It replaces the underlying blkcipher interface with skcipher, and also presents the top-level algorithm as an skcipher. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: api - Do not clear type bits in crypto_larval_lookupHerbert Xu2016-11-281-1/+1
| | | | | | | | | | | | Currently all bits not set in mask are cleared in crypto_larval_lookup. This is unnecessary as wherever the type bits are used it is always masked anyway. This patch removes the clearing so that we may use bits set in the type but not in the mask for special purposes, e.g., picking up internal algorithms.

* crypto: xts - Convert to skcipherHerbert Xu2016-11-281-155/+392
| | | | | | | | | | This patch converts xts over to the skcipher interface. It also optimises the implementation to be based on ECB instead of the underlying cipher. For compatibility the existing naming scheme of xts(aes) is maintained as opposed to the more obvious one of xts(ecb(aes)). Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: drbg - advance output buffer pointerStephan Mueller2016-11-211-0/+1
| | | | | | | | | | | | | | | The CTR DRBG segments the number of random bytes to be generated into 128 byte blocks. The current code misses the advancement of the output buffer pointer when the requestor asks for more than 128 bytes of data. In this case, the next 128 byte block of random numbers is copied to the beginning of the output buffer again. This implies that only the first 128 bytes of the output buffer would ever be filled. The patch adds the advancement of the buffer pointer to fill the entire buffer. Signed-off-by: Stephan Mueller <smueller@chronox.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: engine - Handle the kthread worker using the new APIPetr Mladek2016-10-251-15/+11
| | | | | | | | | | | | | | | | | | | | | | | Use the new API to create and destroy the crypto engine kthread worker. The API hides some implementation details. In particular, kthread_create_worker() allocates and initializes struct kthread_worker. It runs the kthread the right way and stores task_struct into the worker structure. kthread_destroy_worker() flushes all pending works, stops the kthread and frees the structure. This patch does not change the existing behavior except for dynamically allocating struct kthread_worker and storing only the pointer of this structure. It is compile tested only because I did not find an easy way how to run the code. Well, it should be pretty safe given the nature of the change.

* kthread: kthread worker API cleanupPetr Mladek2016-10-111-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A good practice is to prefix the names of functions by the name of the subsystem. The kthread worker API is a mix of classic kthreads and workqueues. Each worker has a dedicated kthread. It runs a generic function that process queued works. It is implemented as part of the kthread subsystem. This patch renames the existing kthread worker API to use the corresponding name from the workqueues API prefixed by kthread_: __init_kthread_worker() -> __kthread_init_worker() init_kthread_worker() -> kthread_init_worker() init_kthread_work() -> kthread_init_work() insert_kthread_work() -> kthread_insert_work() queue_kthread_work() -> kthread_queue_work() flush_kthread_work() -> kthread_flush_work() flush_kthread_worker() -> kthread_flush_worker() Note that the names of DEFINE_KTHREAD_WORK*() macros stay as they are. It is common that the "DEFINE_" prefix has precedence over the subsystem names. Note that INIT() macros and init() functions use different naming scheme. There is no good solution. There are several reasons for this solution: + "init" in the function names stands for the verb "initialize" aka "initialize worker". While "INIT" in the macro names stands for the noun "INITIALIZER" aka "worker initializer". + INIT() macros are used only in DEFINE() macros + init() functions are used close to the other kthread() functions. It looks much better if all the functions use the same scheme. + There will be also kthread_destroy_worker() that will be used close to kthread_cancel_work(). It is related to the init() function. Again it looks better if all functions use the same naming scheme. + there are several precedents for such init() function names, e.g. amd_iommu_init_device(), free_area_init_node(), jump_label_init_type(), regmap_init_mmio_clk(), + It is not an argument but it was inconsistent even before.
