crypto: skcipher - Remove obsolete skcipher_alg helpers

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

As skcipher spawn users can no longer assume the spawn is of type struct skcipher_alg, these helpers are no longer used. Remove them. Signed-off-by: Herbert Xu

crypto: skcipher - Add crypto_spawn_skcipher_alg_common

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

As skcipher spawns can be of two different types (skcipher vs. lskcipher), only the common fields can be accessed. Add a helper to return the common algorithm object. Signed-off-by: Herbert Xu

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. Signed-off-by: Herbert Xu

crypto: skcipher - Use crypto_request_complete

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

Use the crypto_request_complete helper instead of calling the completion function directly. Signed-off-by: Herbert Xu

crypto: skcipher - Add ctx helpers with DMA alignment

2022-12-02T10:12:40+00:00

This patch adds helpers to access the skcipher context structure and request context structure with an added alignment for DMA access. Signed-off-by: Herbert Xu

crypto: skcipher - Allow sync algorithms with large request contexts

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

Some sync algorithms may require a large amount of temporary space during its operations. There is no reason why they should be limited just because some legacy users want to place all temporary data on the stack. Such algorithms can now set a flag to indicate that they need extra request context, which will cause them to be invisible to users that go through the sync_skcipher interface.

crypto: x86 - remove glue helper module

2021-01-14T06:10:29+00:00

All dependencies on the x86 glue helper module have been replaced by local instantiations of the new ECB/CBC preprocessor helper macros, so the glue helper module can be retired. Acked-by: Eric Biggers Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu

crypto: remove cipher routines from public crypto API

2021-01-02T21:41:35+00:00

The cipher routines in the crypto API are mostly intended for templates implementing skcipher modes generically in software, and shouldn't be used outside of the crypto subsystem. So move the prototypes and all related definitions to a new header file under include/crypto/internal. Also, let's use the new module namespace feature to move the symbol exports into a new namespace CRYPTO_INTERNAL. Signed-off-by: Ard Biesheuvel Acked-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: skcipher - use crypto_grab_cipher() and simplify error paths

2020-01-09T03:30:56+00:00

Make skcipher_alloc_instance_simple() use the new function crypto_grab_cipher() to initialize its cipher spawn. This is needed to make all spawns be initialized in a consistent way. Also simplify the error handling by taking advantage of crypto_drop_*() now accepting (as a no-op) spawns that haven't been initialized yet, and by taking advantage of crypto_grab_*() now handling ERR_PTR() names.

crypto: skcipher - pass instance to crypto_grab_skcipher()

2020-01-09T03:30:54+00:00

Initializing a crypto_skcipher_spawn currently requires: 1. Set spawn->base.inst to point to the instance. 2. Call crypto_grab_skcipher(). But there's no reason for these steps to be separate, and in fact this unneeded complication has caused at least one bug, the one fixed by commit 6db43410179b ("crypto: adiantum - initialize crypto_spawn::inst") So just make crypto_grab_skcipher() take the instance as an argument. To keep the function calls from getting too unwieldy due to this extra argument, also introduce a 'mask' variable into the affected places which weren't already using one.
