crypto: akcipher - pass instance to crypto_grab_akcipher() Initializing a crypto_akcipher_spawn currently requires: 1. Set spawn->base.inst to point to the instance. 2. Call crypto_grab_akcipher(). But there's no reason for these steps to be separate, and in fact this unneeded complication has caused at least one bug, the one fixed by commit 6db43410179b ("crypto: adiantum - initialize crypto_spawn::inst") So just make crypto_grab_akcipher() take the instance as an argument. To keep the function call from getting too unwieldy due to this extra argument, also introduce a 'mask' variable into pkcs1pad_create().

crypto: akcipher - Drop sign/verify operations A sig_alg backend has just been introduced and all asymmetric sign/verify algorithms have been migrated to it. The sign/verify operations can thus be dropped from akcipher_alg. It is now purely for asymmetric encrypt/decrypt. Move struct crypto_akcipher_sync_data from internal.h to akcipher.c and unexport crypto_akcipher_sync_{prep,post}(): They're no longer used by sig.c but only locally in akcipher.c. In crypto_akcipher_sync_{prep,post}(), drop various NULL pointer checks for data->dst as they were only necessary for the verify operation. In the crypto_sig_*() API calls, remove the forks that were necessary while algorithms were converted from crypto_akcipher to crypto_sig one by one. In struct akcipher_testvec, remove the "params", "param_len" and "algo" elements as they were only needed for the ecrdsa verify operation. Remove corresponding dead code from test_akcipher_one() as well. Signed-off-by: Lukas Wunner <lukas@wunner.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
