crypto: aead - Remove old AEAD interfaces

2015-08-17T08:53:50+00:00

Now that the AEAD conversion is complete we can rip out the old
AEAD interafce and associated code.

crypto: aead - Add type-safe geniv init/exit helpers

2015-08-17T08:53:44+00:00

This patch adds the helpers aead_init_geniv and aead_exit_geniv
which are type-safe and intended the replace the existing geniv
init/exit helpers.

crypto: aead - Add type-safe function for freeing instances

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

This patch adds a type-safe function for freeing AEAD instances
to struct aead_instance.  This replaces the existing free function
in struct crypto_template which does not know the type of the
instance that it's freeing.

crypto: aead - Fix aead_instance struct size

2015-06-19T06:16:30+00:00

The struct aead_instance is meant to extend struct crypto_instance
by incorporating the extra members of struct aead_alg.  However,
the current layout which is copied from shash/ahash does not specify
the struct fully.  In particular only aead_alg is present.

For shash/ahash this works because users there add extra headroom
to sizeof(struct crypto_instance) when allocating the instance.
Unfortunately for aead, this bit was lost when the new aead_instance
was added.

Rather than fixing it like shash/ahash, this patch simply expands
struct aead_instance to contain what is supposed to be there, i.e.,
adding struct crypto_instance.

In order to not break existing AEAD users, this is done through an
anonymous union.

crypto: aead - Add multiple algorithm registration interface

2015-06-03T02:48:35+00:00

This patch adds the helpers that allow the registration and removal
of multiple algorithms.

crypto: aead - Ignore return value from crypto_unregister_alg

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

No new code should be using the return value of crypto_unregister_alg
as it will become void soon.

crypto: aead - Add aead_alg_instance

2015-06-03T02:48:33+00:00

Now that type-safe init/exit functions exist, they often need
to access the underlying aead_instance.  So this patch adds the
helper aead_alg_instance to access aead_instance from a crypto_aead
object.

crypto: aead - Add crypto_aead_alg_ivsize/maxauthsize

2015-05-25T10:41:25+00:00

AEAD algorithm implementors need to figure out a given algorithm's
IV size and maximum authentication size.  During the transition
this is difficult to do as an algorithm could be new style or old
style.

This patch creates two helpers to make this easier.

crypto: seqiv - Add support for new AEAD interface

2015-05-22T03:25:56+00:00

This patch converts the seqiv IV generator to work with the new
AEAD interface where IV generators are just normal AEAD algorithms.

Full backwards compatibility is paramount at this point since
no users have yet switched over to the new interface.  Nor can
they switch to the new interface until IV generation is fully
supported by it.

So this means we are adding two versions of seqiv alongside the
existing one.  The first one is the one that will be used when
the underlying AEAD algorithm has switched over to the new AEAD
interface.  The second one handles the current case where the
underlying AEAD algorithm still uses the old interface.

Both versions export themselves through the new AEAD interface.
