crypto: ccp - Use pci_enable_msix_range() instead of pci_enable_msix()

2014-04-16T12:40:17+00:00

As result of deprecation of MSI-X/MSI enablement functions
pci_enable_msix() and pci_enable_msi_block() all drivers
using these two interfaces need to be updated to use the
new pci_enable_msi_range()  or pci_enable_msi_exact()
and pci_enable_msix_range() or pci_enable_msix_exact()
interfaces.

crypto: ccp - Account for CCP backlog processing

2014-02-26T21:57:01+00:00

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 error

2014-02-26T21:57:00+00:00

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.

crypto: ccp - Prevent a possible lost CCP command request

2014-02-26T21:57:00+00:00

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.

Change from scheduling work to scheduling a tasklet to perform
the callback operations.

crypto: ccp - Use a single queue for proper ordering of tfm requests

2014-02-09T01:59:24+00:00

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 - Move HMAC calculation down to ccp ops file

2014-02-09T01:59:23+00:00

Move the support to perform an HMAC calculation into
the CCP operations file.  This eliminates the need to
perform a synchronous SHA operation used to calculate
the HMAC.

crypto: ccp - Allow for selective disablement of crypto API algorithms

2014-02-09T01:59:15+00:00

Introduce module parameters that allow for disabling of a
crypto algorithm by not registering the algorithm with the
crypto API.

crypto: ccp - Fix ccp_run_passthru_cmd dma variable assignments

2014-02-09T01:59:14+00:00

There are some suspicious looking lines of code in the new ccp driver, including
one that assigns a variable to itself, and another that overwrites a previous assignment.

This may have been a cut-and-paste error where 'src' was forgotten to be changed to 'dst'.
I have no hardware to test this, so this is untested.
