* crypto: ccp - Account for CCP backlog processingTom Lendacky2014-02-26
| | | | | | | | | | When the crypto layer is able to queue up a command for processing by the CCP on the initial call to ccp_crypto_enqueue_request and the CCP returns -EBUSY, then if the backlog flag is not set the command needs to be freed and not added to the active command list.

* crypto: ccp - Invoke context callback when there is a backlog errorTom Lendacky2014-02-26
| | | | | | | | | | Invoke the callback routine associated with the crypto context if an error is encountered sending the command to the CCP during backlog processing. This is needed to free any resources used by the command. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: ccp - Prevent a possible lost CCP command requestTom Lendacky2014-02-26
| | | | | | | | | | If a CCP command has been queued for processing at the crypto layer then, when dequeueing it for processing, the "can backlog" flag must be set so that the request isn't lost if the CCP backlog queue limit is reached.

* crypto: ccp - Use a single queue for proper ordering of tfm requestsTom Lendacky2014-02-08
| | | | | | | | | Move to a single queue to serialize requests within a tfm. When testing using IPSec with a large number of network connections the per cpu tfm queuing logic was not working properly.

* crypto: ccp - Allow for selective disablement of crypto API algorithmsTom Lendacky2014-02-08
| | | | | | | | | Introduce module parameters that allow for disabling of a crypto algorithm by not registering the algorithm with the crypto API. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: ccp - crypto API interface to the CCP device driverTom Lendacky2013-12-05
These routines provide the support for the interface between the crypto API and the AMD CCP. This includes insuring that requests associated with a given tfm on the same cpu are processed in the order received.
