Added support for SKCIPHER, HASH, RSA and AEAD algorithms. This is intended to be used for CAAM backlogging support. The requests, with backlog flag (e.g. from dm-crypt) will be listed into crypto-engine queue and processed by CAAM when free. While here, I've also made some refactorization. Patches #1 - #4 include some refactorizations on caamalg, caamhash and caampkc. Patch #5 changes the return code of caam_jr_enqueue function to -EINPROGRESS, in case of success, -ENOSPC in case the CAAM is busy, -EIO if it cannot map the caller's descriptor. Patches #6 - #9 integrate crypto_engine into CAAM, for SKCIPHER/AEAD/RSA/HASH algorithms. --- Changes since V3: - update return on ahash_enqueue_req function from patch #9. Changes since V2: - remove patch ("crypto: caam - refactor caam_jr_enqueue"), that added some structures not needed anymore; - use _done_ callback function directly for skcipher and aead; - handle resource leak in case of transfer request to crypto-engine; - update commit messages. Changes since V1: - remove helper function - akcipher_request_cast; - remove any references to crypto_async_request, use specific request type; - remove bypass crypto-engine queue, in case is empty; - update some commit messages; - remove unrelated changes, like whitespaces; - squash some changes from patch #9 to patch #6; - added Reviewed-by. --- Iuliana Prodan (9): crypto: caam - refactor skcipher/aead/gcm/chachapoly {en,de}crypt functions crypto: caam - refactor ahash_done callbacks crypto: caam - refactor ahash_edesc_alloc crypto: caam - refactor RSA private key _done callbacks crypto: caam - change return code in caam_jr_enqueue function crypto: caam - support crypto_engine framework for SKCIPHER algorithms crypto: caam - add crypto_engine support for AEAD algorithms crypto: caam - add crypto_engine support for RSA algorithms crypto: caam - add crypto_engine support for HASH algorithms drivers/crypto/caam/Kconfig | 1 + drivers/crypto/caam/caamalg.c | 416 ++++++++++++++++++----------------------- drivers/crypto/caam/caamhash.c | 341 ++++++++++++++++----------------- drivers/crypto/caam/caampkc.c | 187 +++++++++++------- drivers/crypto/caam/caampkc.h | 10 + drivers/crypto/caam/caamrng.c | 4 +- drivers/crypto/caam/intern.h | 2 + drivers/crypto/caam/jr.c | 37 +++- drivers/crypto/caam/key_gen.c | 2 +- 9 files changed, 523 insertions(+), 477 deletions(-)
