Revert "crypto: run initcalls for generic implementations earlier"

2025-05-05T10:20:44+00:00

This reverts commit c4741b23059794bd99beef0f700103b0d983b3fd.

Crypto API self-tests no longer run at registration time and now
occur either at late_initcall or upon the first use.

Therefore the premise of the above commit no longer exists.  Revert
it and subsequent additions of subsys_initcall and arch_initcall.

Note that lib/crypto calls will stay at subsys_initcall (or rather
downgraded from arch_initcall) because they may need to occur
before Crypto API registration.

crypto: cryptd - Only access common skcipher fields on spawn

2023-10-13T10:27:26+00:00

As skcipher spawns may be of the type lskcipher, only the common
fields may be accessed.  This was already the case but use the
correct helpers to make this more obvious.

crypto: skcipher - Add lskcipher

2023-09-20T05:15:29+00:00

Add a new API type lskcipher designed for taking straight kernel
pointers instead of SG lists.  Its relationship to skcipher will
be analogous to that between shash and ahash.

crypto: cryptd - Add support for cloning hashes

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

Allow cryptd hashes to be cloned.  The underlying hash will be cloned.

crypto: cryptd - Convert hash to use modern init_tfm/exit_tfm

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

The cryptd hash template was still using the obsolete cra_init/cra_exit
interface.  Make it use the modern ahash init_tfm/exit_tfm instead.

crypto: api - Use data directly in completion function

2023-02-13T10:35:14+00:00

This patch does the final flag day conversion of all completion
functions which are now all contained in the Crypto API.

crypto: cryptd - Use request_complete helpers

2023-02-13T10:34:49+00:00

Use the request_complete helpers instead of calling the completion
function directly.

crypto: cryptd - Use subreq for AEAD

2023-02-13T10:34:48+00:00

AEAD reuses the existing request object for its child.  This is
error-prone and unnecessary.  This patch adds a subrequest object
just like we do for skcipher and hash.

This patch also restores the original completion function as we
do for skcipher/hash.

crypto: cryptd - Remove unnecessary skcipher_request_zero

2023-01-27T10:58:09+00:00

Previously the child skcipher request was stored on the stack and
therefore needed to be zeroed.  As it is now dynamically allocated
we no longer need to do so.

crypto: cryptd - Use request context instead of stack for sub-request

2022-11-18T08:59:34+00:00

cryptd is buggy as it tries to use sync_skcipher without going
through the proper sync_skcipher interface.  In fact it doesn't
even need sync_skcipher since it's already a proper skcipher and
can easily access the request context instead of using something
off the stack.
