crypto: ccp - Fix XTS-AES-128 support on v5 CCPs

2017-09-27T12:43:14Z

commit e652399edba99a5497f0d80f240c9075d3b43493 upstream. Version 5 CCPs have some new requirements for XTS-AES: the type field must be specified, and the key requires 512 bits, with each part occupying 256 bits and padded with zeroes.

crypto: ccp - Add debugfs entries for CCP information

2017-06-19T06:11:47Z

Expose some data about the configuration and operation of the CCP through debugfs entries: device name, capabilities, configuration, statistics. Allow the user to reset the counters to zero by writing (any value) to the 'stats' file. This can be done per queue or per device.

crypto: ccp - Change ISR handler method for a v3 CCP

2017-04-24T10:11:06Z

The CCP has the ability to perform several operations simultaneously, but only one interrupt. When implemented as a PCI device and using MSI-X/MSI interrupts, use a tasklet model to service interrupts. By disabling and enabling interrupts from the CCP, coupled with the queuing that tasklets provide, we can ensure that all events (occurring on the device) are recognized and serviced. This change fixes a problem wherein 2 or more busy queues can cause notification bits to change state while a (CCP) interrupt is being serviced, but after the queue state has been evaluated. This results in the event being 'lost' and the queue hanging, waiting to be serviced. Since the status bits are never fully de-asserted, the CCP never generates another interrupt (all bits zero -> one or more bits one), and no further CCP operations will be executed.

crypto: ccp - Use only the relevant interrupt bits

2017-04-21T12:30:56Z

Each CCP queue can product interrupts for 4 conditions: operation complete, queue empty, error, and queue stopped. This driver only works with completion and error events. Cc: # 4.9.x+ Signed-off-by: Gary R Hook Signed-off-by: Herbert Xu

crypto: ccp - Rearrange structure members to minimize size

2017-04-05T13:58:35Z

The AES GCM function (in ccp-ops) requires a fair amount of stack space, which elicits a complaint when KASAN is enabled. Rearranging and packing a few structures eliminates the warning. Signed-off-by: Gary R Hook Signed-off-by: Herbert Xu

crypto: ccp - Enable 3DES function on v5 CCPs

crypto: ccp - Make some CCP DMA channels private

2017-03-24T13:51:34Z

The CCP registers its queues as channels capable of handling general DMA operations. The NTB driver will use DMA if directed, but as public channels can be reserved for use in asynchronous operations some channels should be held back as private. Since the public/private determination is handled at a device level, reserve the "other" (secondary) CCP channels as private. Add a module parameter that allows for override, to be applied to all channels on all devices. CC: # 4.10.x- Signed-off-by: Gary R Hook Signed-off-by: Herbert Xu

crypto: ccp - Set the AES size field for all modes

crypto: ccp - Fix double add when creating new DMA command

2017-02-03T09:45:46Z

Eliminate a double-add by creating a new list to manage command descriptors when created; move the descriptor to the pending list when the command is submitted. Cc: Signed-off-by: Gary R Hook Signed-off-by: Herbert Xu
