This patch changes cryptd to use the new style ahash type. In
particular, the instance is enlarged to encapsulate the new
ahash_alg structure.Signed-off-by: Herbert Xu
-
This patch changes cryptd to use the template->create function
instead of alloc in anticipation for the switch to new style
ahash algorithms.Signed-off-by: Herbert Xu
-
This patch adds the helpers crypto_drop_ahash and crypto_drop_shash
so that these spawns can be dropped without ugly casts.Signed-off-by: Herbert Xu
-
This patch adds a mask parameter to complement the existing type
parameter. This is useful when instantiating algorithms that
require a mask other than the default, e.g., ahash algorithms.Signed-off-by: Herbert Xu
-
This patch adds support for creating ahash instances and using
ahash as spawns.Signed-off-by: Herbert Xu
-
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.Signed-off-by: Herbert Xu
-
As the extsize and init_tfm functions belong to the frontend the
frontend argument is superfluous.Signed-off-by: Herbert Xu
-
This patch makes crypto4xx use crypto_ahash_set_reqsize to avoid
accessing crypto_ahash directly.Signed-off-by: Herbert Xu
-
This patch makes cryptd use crypto_ahash_set_reqsize to avoid
accessing crypto_ahash directly.Signed-off-by: Herbert Xu
-
This patch adds the helper crypto_ahash_set_reqsize so that
implementations do not directly access the crypto_ahash structure.Signed-off-by: Herbert Xu
-
This patch changes cryptd to use shash algorithms instead of the
legacy hash interface.Signed-off-by: Herbert Xu
-
This patch exports the async functions so that they can be reused
by cryptd when it switches over to using shash.Signed-off-by: Herbert Xu
-
This patch removes the implementation of hash and digest now that
no algorithms use them anymore. The interface though will remain
until the users are converted across.Signed-off-by: Herbert Xu
-
Now that there are no more legacy hash implementations we can
remove the reference to crypto_hash.Signed-off-by: Herbert Xu
-
This patch converts the xcbc algorithm to the new shash type.
Signed-off-by: Herbert Xu
-
This patch changes hmac to the new shash interface.
Signed-off-by: Herbert Xu
-
This patch converts the padlock-sha implementation to shash.
In doing so the existing mechanism of storing the data until
final is no longer viable as we do not have a way of allocating
data in crypto_shash_init and then reliably freeing it.This is just as well because a better way of handling the problem
is to hash everything but the last chunk using normal sha code
and then provide the intermediate result to the padlock device.This is good enough because the primary application of padlock-sha
is IPsec and there the data is laid out in the form of an hmac
header followed by the rest of the packet. In essence we can
provide all the data to the padlock as the hmac header only needs
to be hashed once.Signed-off-by: Herbert Xu
-
This patch changes descsize to a run-time attribute so that
implementations can change it in their init functions.Signed-off-by: Herbert Xu

This patch changes the kfree call to kzfree for async requests.
As the request may contain sensitive data it needs to be zeroed
before it can be reallocated by others.Signed-off-by: Herbert Xu
-
This patch moves the run-time null setkey check to shash_prepare_alg
just like we did for finup/digest.Signed-off-by: Herbert Xu

This patch changes padlock sha fallback to shash instead of hash.
Signed-off-by: Herbert Xu
-
This patch adds export/import support to sha256-s390. The exported
type is defined by struct sha256_state, which is basically the entire
descriptor state of sha256_generic.Signed-off-by: Herbert Xu
-
This patch adds export/import support to sha1-s390. The exported
type is defined by struct sha1_state, which is basically the entire
descriptor state of sha1_generic.Signed-off-by: Herbert Xu
-
This patch adds export/import support to sha256_generic. The exported
type is defined by struct sha256_state, which is basically the entire
descriptor state of sha256_generic.Signed-off-by: Herbert Xu
-
This patch replaces the two 32-bit counter code in sha256_generic
with the simpler 64-bit counter code from sha1.Signed-off-by: Herbert Xu
-
This patch adds export/import support to sha1_generic. The exported
type is defined by struct sha1_state, which is basically the entire
descriptor state of sha1_generic.Signed-off-by: Herbert Xu
-
This patch moves the run-time null finup/digest checks to the
shash_prepare_alg function which is run at registration time.Signed-off-by: Herbert Xu
-
This patch replaces the full descriptor export with an export of
the partial hash state. This allows the use of a consistent export
format across all implementations of a given algorithm.This is useful because a number of cases require the use of the
partial hash state, e.g., PadLock can use the SHA1 hash state
to get around the fact that it can only hash contiguous data
chunks.Signed-off-by: Herbert Xu

This patch allows crypto_drop_spawn to be called on spawns that
have not been initialised or have failed initialisation. This
fixes potential crashes during initialisation without adding
special case code.Signed-off-by: Herbert Xu
-
This patch adds the helper shash_instance_ctx which is the shash
analogue of crypto_instance_ctx.Signed-off-by: Herbert Xu

This patch fixes crypto_shash_import to propagate the value returned
by reinit.Signed-off-by: Herbert Xu
-
This patch simplifies the default digest function by using finup.
Signed-off-by: Herbert Xu
-
This patch adds __crypto_shash_cast which turns a crypto_tfm
into crypto_shash. It's analogous to the other __crypto_*_cast
functions.It hasn't been needed until now since no existing shash algorithms
have had an init function.Signed-off-by: Herbert Xu
-
This patch adds crypto_shash_ctx_aligned which will be needed
by hmac after its conversion to shash.Signed-off-by: Herbert Xu
-
This patch adds shash_register_instance so that shash instances
can be registered without bypassing the shash checks applied to
normal algorithms.Signed-off-by: Herbert Xu
-
This patch adds the helper shash_attr_alg2 which locates a shash
algorithm based on the information in the given attribute.Signed-off-by: Herbert Xu
-
This patch adds the helper crypto_attr_alg2 which is similar to
crypto_attr_alg but takes an extra frontend argument. This is
intended to be used by new style algorithm types such as shash.Signed-off-by: Herbert Xu
-
This patch adds the functions needed to create and use shash
spawns, i.e., to use shash algorithms in a template.Signed-off-by: Herbert Xu
-
This patch modifies the spawn infrastructure to support new style
algorithms like shash. In particular, this means storing the
frontend type in the spawn and using crypto_create_tfm to allocate
the tfm.Signed-off-by: Herbert Xu
-
This patch adds shash_instance and the associated alloc/free
functions. This is meant to be an instance that with a shash
algorithm under it. Note that the instance itself doesn't have
to be shash.Signed-off-by: Herbert Xu
