crypto: ahash - Add crypto_ahash_tested() helper function

2025-06-26T10:52:33+00:00

Add a little inline helper function crypto_ahash_tested() to the internal/hash.h header file to retrieve the tested status (that is the CRYPTO_ALG_TESTED bit in the cra_flags). Signed-off-by: Harald Freudenberger Suggested-by: Herbert Xu Reviewed-by: Holger Dengler Signed-off-by: Herbert Xu

crypto: ahash - make hash walk functions from ahash.c public

2025-06-26T10:52:33+00:00

Make the hash walk functions crypto_hash_walk_done() crypto_hash_walk_first() crypto_hash_walk_last() public again. These functions had been removed from the header file include/crypto/internal/hash.h with commit 7fa481734016 ("crypto: ahash - make hash walk functions private to ahash.c") as there was no crypto algorithm code using them. With the upcoming crypto implementation for s390 phmac these functions will be exploited and thus need to be public within the kernel again.

crypto: ahash - Stop legacy tfms from using the set_virt fallback path

2025-06-23T09:00:27+00:00

Ensure that drivers that have not been converted to the ahash API do not use the ahash_request_set_virt fallback path as they cannot use the software fallback. Reported-by: Eric Biggers Fixes: 9d7a0ab1c753 ("crypto: ahash - Handle partial blocks in API") Signed-off-by: Herbert Xu

Revert "crypto: testmgr - Add hash export format testing"

2025-05-23T09:20:59+00:00

This reverts commit 18c438b228558e05ede7dccf947a6547516fc0c7. The s390 hmac and sha3 algorithms are failing the test. Revert the change until they have been fixed.

crypto: testmgr - Add hash export format testing

2025-05-19T05:48:20+00:00

Ensure that the hash state can be exported to and imported from the generic algorithm. Signed-off-by: Herbert Xu

crypto: hmac - Add ahash support

2025-05-19T05:48:20+00:00

Add ahash support to hmac so that drivers that can't do hmac in hardware do not have to implement duplicate copies of hmac. Signed-off-by: Herbert Xu

crypto: hash - Add export_core and import_core hooks

2025-05-19T05:48:19+00:00

Add export_core and import_core hooks. These are intended to be used by algorithms which are wrappers around block-only algorithms, but are not themselves block-only, e.g., hmac. Signed-off-by: Herbert Xu

crypto: hash - Move core export and import into internel/hash.h

2025-05-19T05:48:19+00:00

The core export and import functions are targeted at implementors so move them into internal/hash.h. Signed-off-by: Herbert Xu

crypto: ahash - Add HASH_REQUEST_ZERO

2025-05-05T10:20:46+00:00

Add a helper to zero hash stack requests that were never cloned off the stack. Signed-off-by: Herbert Xu

crypto: api - Rename CRYPTO_ALG_REQ_CHAIN to CRYPTO_ALG_REQ_VIRT

2025-05-05T10:20:45+00:00

As chaining has been removed, all that remains of REQ_CHAIN is just virtual address support. Rename it before the reintroduction of batching creates confusion. Signed-off-by: Herbert Xu
