2024-09-10qapi/cryptodev: Rename QCryptodevBackendAlgType to *Algo, and drop prefixMarkus Armbruster
QAPI's 'prefix' feature can make the connection between enumeration type and its constants less than obvious. It's best used with restraint. QCryptodevBackendAlgType has a 'prefix' that overrides the generated enumeration constants' prefix to QCRYPTODEV_BACKEND_ALG. We could simply drop 'prefix', but I think the abbreviation "alg" is less than clear. Additionally rename the type to QCryptodevBackendAlgoType. The prefix becomes QCRYPTODEV_BACKEND_ALGO_TYPE.

2022-06-16crypto: Introduce RSA algorithmzhenwei pi
There are two parts in this patch: 1, support akcipher service by cryptodev-builtin driver 2, virtio-crypto driver supports akcipher service In principle, we should separate this into two patches, to avoid compiling error, merge them into one. Then virtio-crypto gets request from guest side, and forwards the request to builtin driver to handle it. Test with a guest linux: 1, The self-test framework of crypto layer works fine in guest kernel 2, Test with Linux guest(with asym support), the following script test(note that pkey_XXX is supported only in a newer version of keyutils): - both public key & private key - create/close session - encrypt/decrypt/sign/verify basic driver operation - also test with kernel crypto layer(pkey add/query) All the cases work fine.
