crypto: engine - remove request batching support

2025-07-18T10:52:00+00:00

Remove request batching support from crypto_engine, as there are no drivers using this feature and it doesn't really work that well. Instead of doing batching based on backlog, a more optimal approach would be for the user to handle the batching (similar to how IPsec can hook into GSO to get 64K of data each time or how block encryption can use unit sizes much greater than 4K).

crypto: engine - Make crypto_engine_exit() return void

2023-10-01T08:28:15+00:00

All callers ignore the return value, so simplify by not providing one. Note that crypto_engine_exit() is typically called in a device driver's remove path (or the error path in probe), where errors cannot be handled anyhow. Signed-off-by: Uwe Kleine-König Signed-off-by: Herbert Xu

crypto: engine - Remove crypto_engine_ctx

2023-08-18T09:01:11+00:00

Remove the obsolete crypto_engine_ctx structure. Signed-off-by: Herbert Xu

crypto: engine - Move crypto_engine_ops from request into crypto_alg

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

Rather than having the callback in the request, move it into the crypto_alg object. This avoids having crypto_engine look into the request context is private to the driver. Signed-off-by: Herbert Xu

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. Signed-off-by: Herbert Xu

crypto: engine - Move crypto inclusions out of header file

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

The engine file does not need the actual crypto type definitions so move those header inclusions to where they are actually used. Signed-off-by: Herbert Xu

crypto: engine - Remove prepare/unprepare request

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

The callbacks for prepare and unprepare request in crypto_engine is superfluous. They can be done directly from do_one_request. Move the code into do_one_request and remove the unused callbacks. Signed-off-by: Herbert Xu

crypto: engine - Fix struct crypto_engine_op doc

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

Remove redundant underscore and fix some grammar in prepare_request doc. Signed-off-by: David Yang Acked-by: Randy Dunlap Signed-off-by: Herbert Xu

crypto: api - Replace kernel.h with the necessary inclusions

2021-12-17T05:59:48+00:00

When kernel.h is used in the headers it adds a lot into dependency hell, especially when there are circular dependencies are involved. Replace kernel.h inclusion with the list of what is really being used. Signed-off-by: Andy Shevchenko Signed-off-by: Herbert Xu

crypto: engine - Add KPP Support to Crypto Engine

2021-10-29T13:04:03+00:00

Add KPP support to the crypto engine queue manager, so that it can be used to simplify the logic of KPP device drivers as done for other crypto drivers. Signed-off-by: Prabhjot Khurana Signed-off-by: Daniele Alessandrelli Signed-off-by: Herbert Xu
