crypto: engine - Move struct crypto_engine into internal/engine.h

2023-08-18T09:01:10+00:00

Most drivers should not access the internal details of struct
crypto_engine.  Move it into the internal header file.

crypto: engine - Create internal/engine.h

2023-08-18T09:01:10+00:00

Create crypto/internal/engine.h to house details that should not
be used by drivers.  It is empty for the time being.

crypto: sig - Add interface for sign/verify

2023-06-23T08:15:36+00:00

Split out the sign/verify functionality from the existing akcipher
interface.  Most algorithms in akcipher either support encryption
and decryption, or signing and verify.  Only one supports both.

As a signature algorithm may not support encryption at all, these
two should be spearated.

For now sig is simply a wrapper around akcipher as all algorithms
remain unchanged.  This is a first step and allows users to start
allocating sig instead of akcipher.

crypto: cipher - Add crypto_clone_cipher

2023-05-24T10:12:33+00:00

Allow simple ciphers to be cloned, if they don't have a cra_init
function.  This basically rules out those ciphers that require a
fallback.

In future simple ciphers will be eliminated, and replaced with a
linear skcipher interface.  When that happens this restriction will
disappear.

crypto: hash - Make crypto_ahash_alg helper available

2023-05-12T10:48:01+00:00

Move the crypto_ahash_alg helper into include/crypto/internal so
that drivers can use it.

crypto: hash - Add statesize to crypto_ahash

2023-05-12T10:48:01+00:00

As ahash drivers may need to use fallbacks, their state size
is thus variable.  Deal with this by making it an attribute
of crypto_ahash.

crypto: hash - Add crypto_clone_ahash/shash

2023-04-20T10:20:04+00:00

This patch adds the helpers crypto_clone_ahash and crypto_clone_shash.
They are the hash-specific counterparts of crypto_clone_tfm.

This allows code paths that cannot otherwise allocate a hash tfm
object to do so.  Once a new tfm has been obtained its key could
then be changed without impacting other users.

Note that only algorithms that implement clone_tfm can be cloned.
However, all keyless hashes can be cloned by simply reusing the
tfm object.

crypto: acomp - Count error stats differently

2023-03-14T09:06:42+00:00

Move all stat code specific to acomp into the acomp code.

While we're at it, change the stats so that bytes and counts
are always incremented even in case of error.  This allows the
reference counting to be removed as we can now increment the
counters prior to the operation.

After the operation we simply increase the error count if necessary.
This is safe as errors can only occur synchronously (or rather,
the existing code already ignored asynchronous errors which are
only visible to the callback function).

crypto: skcipher - Use crypto_request_complete

Use the crypto_request_complete helper instead of calling the
completion function directly.
