crypto: hash - Remove crypto_hash interface

2016-02-06T07:33:20+00:00

This patch removes all traces of the crypto_hash interface, now
that everyone has switched over to shash or ahash.

crypto: engine - Introduce the block request crypto engine framework

2016-02-01T14:27:02+00:00

Now block cipher engines need to implement and maintain their own queue/thread
for processing requests, moreover currently helpers provided for only the queue
itself (in crypto_enqueue_request() and crypto_dequeue_request()) but they
don't help with the mechanics of driving the hardware (things like running the
request immediately, DMA map it or providing a thread to process the queue in)
even though a lot of that code really shouldn't vary that much from device to
device.

Thus this patch provides a mechanism for pushing requests to the hardware
as it becomes free that drivers could use. And this framework is patterned
on the SPI code and has worked out well there.

This patch introduces crypto_queue_len() helper function to help to get the
queue length in the crypto queue list now.

crypto: api - Add instance free function to crypto_type

2015-07-14T06:56:45+00:00

Currently the task of freeing an instance is given to the crypto
template.  However, it has no type information on the instance so
we have to resort to checking type information at runtime.

This patch introduces a free function to crypto_type that will be
used to free an instance.  This can then be used to free an instance
in a type-safe manner.

crypto: api - Remove unused __crypto_dequeue_request

2015-07-14T06:56:44+00:00

The function __crypto_dequeue_request is completely unused.

crypto: aead - Convert top level interface to new style

2015-05-13T02:31:53+00:00

This patch converts the top-level aead interface to the new style.
All user-level AEAD interface code have been moved into crypto/aead.h.

The allocation/free functions have switched over to the new way of
allocating tfms.

This patch also removes the double indrection on setkey so the
indirection now exists only at the alg level.

Apart from these there are no user-visible changes.

crypto: api - Add crypto_grab_spawn primitive

2015-05-13T02:31:25+00:00

This patch adds a new primitive crypto_grab_spawn which is meant
to replace crypto_init_spawn and crypto_init_spawn2.  Under the
new scheme the user no longer has to worry about reference counting
the alg object before it is subsumed by the spawn.

It is pretty much an exact copy of crypto_grab_aead.

Prior to calling this function spawn->frontend and spawn->inst
must have been set.

crypto: api - Change crypto_unregister_instance argument type

2015-04-03T09:53:32+00:00

This patch makes crypto_unregister_instance take a crypto_instance
instead of a crypto_alg.  This allows us to remove a duplicate
CRYPTO_ALG_INSTANCE check in crypto_unregister_instance.

crypto: api - Move crypto_yield() to algapi.h

2014-06-20T13:26:04+00:00

It makes no sense for crypto_yield() to be defined in scatterwalk.h ,
move it into algapi.h as it's an internal function to crypto API.

crypto: allow blkcipher walks over AEAD data

2014-03-10T12:17:11+00:00

This adds the function blkcipher_aead_walk_virt_block, which allows the caller
to use the blkcipher walk API to handle the input and output scatterlists.
