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. Run script in guest: rm -rf *.der *.pem *.pfx modprobe pkcs8_key_parser # if CONFIG_PKCS8_PRIVATE_KEY_PARSER=m rm -rf /tmp/data dd if=/dev/random of=/tmp/data count=1 bs=20 openssl req -nodes -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -subj "/C=CN/ST=BJ/L=HD/O=qemu/OU=dev/CN=qemu/emailAddress=qemu@qemu.org" openssl pkcs8 -in key.pem -topk8 -nocrypt -outform DER -out key.der openssl x509 -in cert.pem -inform PEM -outform DER -out cert.der PRIV_KEY_ID=`cat key.der | keyctl padd asymmetric test_priv_key @s` echo "priv key id = "$PRIV_KEY_ID PUB_KEY_ID=`cat cert.der | keyctl padd asymmetric test_pub_key @s` echo "pub key id = "$PUB_KEY_ID keyctl pkey_query $PRIV_KEY_ID 0 keyctl pkey_query $PUB_KEY_ID 0 echo "Enc with priv key..." keyctl pkey_encrypt $PRIV_KEY_ID 0 /tmp/data enc=pkcs1 >/tmp/enc.priv echo "Dec with pub key..." keyctl pkey_decrypt $PRIV_KEY_ID 0 /tmp/enc.priv enc=pkcs1 >/tmp/dec cmp /tmp/data /tmp/dec echo "Sign with priv key..." keyctl pkey_sign $PRIV_KEY_ID 0 /tmp/data enc=pkcs1 hash=sha1 > /tmp/sig echo "Verify with pub key..." keyctl pkey_verify $PRIV_KEY_ID 0 /tmp/data /tmp/sig enc=pkcs1 hash=sha1 echo "Enc with pub key..." keyctl pkey_encrypt $PUB_KEY_ID 0 /tmp/data enc=pkcs1 >/tmp/enc.pub echo "Dec with priv key..." keyctl pkey_decrypt $PRIV_KEY_ID 0 /tmp/enc.pub enc=pkcs1 >/tmp/dec cmp /tmp/data /tmp/dec echo "Verify with pub key..." keyctl pkey_verify $PUB_KEY_ID 0 /tmp/data /tmp/sig enc=pkcs1 hash=sha1 Reviewed-by: Gonglei <arei.gonglei@huawei.com> Signed-off-by: lei he <helei.sig11@bytedance.com Signed-off-by: zhenwei pi <pizhenwei@bytedance.com> Message-Id: <20220611064243.24535-2-pizhenwei@bytedance.com> Reviewed-by: Michael S.
