crypto: hash - Fix async import on shash algorithm

2010-11-04T18:48:37+00:00

The function shash_async_import did not initialise the descriptor
correctly prior to calling the underlying shash import function.

This patch adds the required initialisation.

crypto: shash - Remove usage of CRYPTO_MINALIGN

2010-05-19T01:50:58+00:00

The macro CRYPTO_MINALIGN is not meant to be used directly.  This
patch replaces it with crypto_tfm_ctx_alignment.

crypto: shash - Test for the algorithms import function before exporting it

2009-07-24T05:57:13+00:00

crypto_init_shash_ops_async() tests for setkey and not for import
before exporting the algorithms import function to ahash.
This patch fixes this.

crypto: shash - Require all algorithms to support export/import

2009-07-22T06:38:13+00:00

This patch provides a default export/import function for all
shash algorithms.  It simply copies the descriptor context as
is done by sha1_generic.

This in essence means that all existing shash algorithms now
support export/import.  This is something that will be depended
upon in implementations such as hmac.  Therefore all new shash
and ahash implementations must support export/import.

For those that cannot obtain a partial result, padlock-sha's
fallback model should be used so that a partial result is always
available.

crypto: shash - Fix async finup handling of null digest

2009-07-15T13:26:41+00:00

When shash_ahash_finup encounters a null request, we end up not
calling the underlying final function.  This patch fixes that.

crypto: ahash - Add unaligned handling and default operations

2009-07-15T04:40:40+00:00

This patch exports the finup operation where available and adds
a default finup operation for ahash.  The operations final, finup
and digest also will now deal with unaligned result pointers by
copying it.  Finally export/import operations are will now be
exported too.

crypto: shash - Fix alignment in unaligned operations

2009-07-14T13:43:56+00:00

When we encounter an unaligned pointer we are supposed to copy
it to a temporary aligned location.  However the temporary buffer
isn't aligned properly.  This patch fixes that.

crypto: hash - Zap unaligned buffers

2009-07-14T13:35:36+00:00

Some unaligned buffers on the stack weren't zapped properly which
may cause secret data to be leaked.  This patch fixes them by doing
a zero memset.

It is also possible for us to place random kernel stack contents
in the digest buffer if a digest operation fails.  This is fixed
by only copying if the operation succeeded.

crypto: ahash - Remove old_ahash_alg

2009-07-14T12:29:57+00:00

Now that all ahash implementations have been converted to the new
ahash type, we can remove old_ahash_alg and its associated support.

crypto: ahash - Convert to new style algorithms

2009-07-14T07:54:07+00:00

This patch converts crypto_ahash to the new style.  The old ahash
algorithm type is retained until the existing ahash implementations
are also converted.  All ahash users will automatically get the
new crypto_ahash type.
