crypto: api - Clear CRYPTO_ALG_DEAD bit before registering an alg

2017-02-09T07:08:26+00:00

commit d6040764adcb5cb6de1489422411d701c158bb69 upstream.

Make sure CRYPTO_ALG_DEAD bit is cleared before proceeding with
the algorithm registration. This fixes qat-dh registration when
driver is restarted

crypto: api - Add crypto_inst_setname

2016-07-01T15:45:11+00:00

This patch adds the helper crypto_inst_setname because the current
helper crypto_alloc_instance2 is no longer useful given that we
now look up the algorithm after we allocate the instance object.

crypto: api - Add crypto_type_has_alg helper

2016-01-25T14:42:12+00:00

This patch adds the helper crypto_type_has_alg which is meant
to replace crypto_has_alg for new-style crypto types.  Rather
than hard-coding type/mask information they're now retrieved
from the crypto_type object.

crypto: api - use list_first_entry_or_null and list_next_entry

2015-11-23T12:55:50+00:00

Simplify crypto_more_spawns() with list_first_entry_or_null()
and list_next_entry().

crypto: api - Only abort operations on fatal signal

2015-10-20T13:59:25+00:00

Currently a number of Crypto API operations may fail when a signal
occurs.  This causes nasty problems as the caller of those operations
are often not in a good position to restart the operation.

In fact there is currently no need for those operations to be
interrupted by user signals at all.  All we need is for them to
be killable.

This patch replaces the relevant calls of signal_pending with
fatal_signal_pending, and wait_for_completion_interruptible with
wait_for_completion_killable, respectively.

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: api - Include alignment in crypto_alg_extsize

2015-06-03T02:48:34+00:00

This patch ensures that the tfm context always has enough extra
memory to ensure that it is aligned according to cra_alignment.

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 - Fix build error when modules are disabled

2015-04-26T06:33:15+00:00

The commit 59afdc7b32143528524455039e7557a46b60e4c8 ("crypto:
api - Move module sig ifdef into accessor function") broke the
build when modules are completely disabled because we directly
dereference module->name.

This patch fixes this by using the accessor function module_name.
