crypto: echainiv - Remove AEAD compatibility code

2015-08-17T08:53:43+00:00

Now that we no longer have any legacy AEAD implementations the
compatibility code path can no longer be triggered.  This patch
removes it.

crypto: echainiv - Fix encryption convention

2015-07-14T06:56:46+00:00

This patch fixes a bug where we were incorrectly including the
IV in the AD during encryption.  The IV must remain in the plain
text for it to be encrypted.

During decryption there is no need to copy the IV to dst because
it's now part of the AD.

This patch removes an unncessary check on authsize which would be
performed by the underlying decrypt call.

Finally this patch makes use of the type-safe init/exit functions.

crypto: echainiv - Only hold RNG during initialisation

2015-06-22T07:49:29+00:00

This patch changes the RNG allocation so that we only hold a
reference to the RNG during initialisation.

crypto: echainiv - Move IV seeding into init function

2015-06-04T07:05:00+00:00

We currently do the IV seeding on the first givencrypt call in
order to conserve entropy.  However, this does not work with
DRBG which cannot be called from interrupt context.  In fact,
with DRBG we don't need to conserve entropy anyway.  So this
patch moves the seeding into the init function.

crypto: echainiv - Fix IV size in context size calculation

2015-05-28T03:23:18+00:00

This patch fixes a bug in the context size calculation where we
were still referring to the old cra_aead.

crypto: echainiv - Use common IV generation code

2015-05-28T03:23:18+00:00

This patch makes use of the new common IV generation code.

crypto: echainiv - Copy AD along with plain text

2015-05-28T03:23:18+00:00

As the AD does not necessarily exist in the destination buffer
it must be copied along with the plain text.

crypto: aead - Remove unused cryptoff parameter

2015-05-25T10:41:32+00:00

This patch removes the cryptoff parameter now that all users
set it to zero.

crypto: echainiv - Stop using cryptoff

2015-05-25T10:41:31+00:00

The cryptoff parameter was added to facilitate the skipping of
IVs that sit between the AD and the plain/cipher text.  However,
it was never implemented correctly as and we do not handle users
such as IPsec setting cryptoff.  It is simply ignored.

Implementing correctly is in fact more trouble than what it's
worth.

This patch removes the uses of cryptoff and simply falls back
to using the old AEAD interface as it's only needed for old AEAD
implementations.
