crypto: af_alg - Fix incorrect boolean values in af_alg_ctx

2025-09-24T21:43:32Z

Commit 1b34cbbf4f01 ("crypto: af_alg - Disallow concurrent writes in af_alg_sendmsg") changed some fields from bool to 1-bit bitfields of type u32. However, some assignments to these fields, specifically 'more' and 'merge', assign values greater than 1. These relied on C's implicit conversion to bool, such that zero becomes false and nonzero becomes true. With a 1-bit bitfields of type u32 instead, mod 2 of the value is taken instead, resulting in 0 being assigned in some cases when 1 was intended. Fix this by restoring the bool type.

crypto: af_alg - Disallow concurrent writes in af_alg_sendmsg

2025-09-18T09:24:59Z

Issuing two writes to the same af_alg socket is bogus as the data will be interleaved in an unpredictable fashion. Furthermore, concurrent writes may create inconsistencies in the internal socket state. Disallow this by adding a new ctx->write field that indiciates exclusive ownership for writing.

crypto: engine - remove {prepare,unprepare}_crypt_hardware callbacks

2025-07-18T10:52:00Z

The {prepare,unprepare}_crypt_hardware callbacks were added back in 2016 by commit 735d37b5424b ("crypto: engine - Introduce the block request crypto engine framework"), but they were never implemented by any driver. Remove them as they are unused. Since the 'engine->idling' and 'was_busy' flags are no longer needed, remove them as well. Signed-off-by: Ovidiu Panait Signed-off-by: Herbert Xu

crypto: engine - remove request batching support

2025-07-18T10:52:00Z

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).
