Integrate crypto_engine framework into CAAM, to make use of the engine queue. 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. Patches #5, #6 change 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. Also, to keep each request information, like backlog flag, a new struct is passed as argument to enqueue function. Patches #7 - #10 integrate crypto_engine into CAAM, for SKCIPHER/AEAD/RSA/HASH algorithms. --- 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 (10): 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 - refactor caam_jr_enqueue 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 | 450 +++++++++++++++++++---------------------- drivers/crypto/caam/caamhash.c | 357 +++++++++++++++++--------------- drivers/crypto/caam/caampkc.c | 205 ++++++++++++------- drivers/crypto/caam/caampkc.h | 22 ++ drivers/crypto/caam/caamrng.c | 4 +- drivers/crypto/caam/intern.h | 3 + drivers/crypto/caam/jr.c | 37 +++- drivers/crypto/caam/key_gen.c | 2 +- 9 files changed, 597 insertions(+), 484 deletions(-) -- 2.1.0
