[PATCH v6 0/9] Introduce akcipher service for virtio-crypto
v5 -> v6:
- Fix build errors and codestyles.
- Add parameter 'Error **errp' for qcrypto_akcipher_rsakey_parse.
- Report more detailed errors.
- Fix buffer length check and return values of akcipher-nettle, allows caller to
pass a buffer with larger size than actual needed.
A million thanks to Daniel!
v4 -> v5:
- Move QCryptoAkCipher into akcipherpriv.h, and modify the related comments.
- Rename asn1_decoder.c to der.c.
- Code style fix: use 'cleanup' & 'error' lables.
- Allow autoptr type to auto-free.
- Add test cases for rsakey to handle DER error.
- Other minor fixes.
v3 -> v4:
- Coding style fix: Akcipher -> AkCipher, struct XXX -> XXX, Rsa ->
RSA,
XXX-alg -> XXX-algo.
- Change version info in qapi/crypto.json, from 7.0 -> 7.1.
- Remove ecdsa from qapi/crypto.json, it would be introduced with the
implemetion later.
- Use QCryptoHashAlgothrim instead of QCryptoRSAHashAlgorithm(removed) in
qapi/crypto.json.
- Rename arguments of qcrypto_akcipher_XXX to keep aligned with
qcrypto_cipher_XXX(dec/enc/sign/vefiry -> in/out/in2), and add
qcrypto_akcipher_max_XXX APIs.
- Add new API: qcrypto_akcipher_supports.
- Change the return value of qcrypto_akcipher_enc/dec/sign, these functions
return the actual length of result.
- Separate ASN.1 source code and test case clean.
- Disable RSA raw encoding for akcipher-nettle.
- Separate RSA key parser into rsakey.{hc}, and implememts it with
builtin-asn1-decoder and nettle respectivly.
- Implement RSA(pkcs1 and raw encoding) algorithm by gcrypt. This has higher
priority than nettle.
- For some akcipher operations(eg, decryption of pkcs1pad(rsa)), the length of
returned result maybe less than the dst buffer size, return the actual length of
result instead of the buffer length to the guest side. (in function
virtio_crypto_akcipher_input_data_helper)
- Other minor changes.
Thanks to Daniel!
Eric pointed out this missing part of use case, send it here again.
In our plan, the feature is designed for HTTPS offloading case and other
applications which use kernel RSA/ecdsa by keyctl syscall. The full picture
shows bellow:
Nginx/openssl[1] ... Apps
Guest -----------------------------------------
virtio-crypto driver[2]
-------------------------------------------------
virtio-crypto backend[3]
Host -----------------------------------------
/ | \
builtin[4] vhost keyctl[5] ...
[1] User applications can offload RSA calculation to kernel by keyctl syscall.
There is no keyctl engine in openssl currently, we developed a engine and tried
to contribute it to openssl upstream, but openssl 1.x does not accept new
feature. Link:
https://github.com/openssl/openssl/pull/16689
This branch is available and maintained by Lei <helei.sig11 at
bytedance.com>
https://github.com/TousakaRin/openssl/tree/OpenSSL_1_1_1-kctl_engine
We tested nginx(change config file only) with openssl keyctl engine, it works
fine.
[2] virtio-crypto driver is used to communicate with host side, send requests to
host side to do asymmetric calculation.
https://lkml.org/lkml/2022/3/1/1425
[3] virtio-crypto backend handles requests from guest side, and forwards request
to crypto backend driver of QEMU.
[4] Currently RSA is supported only in builtin driver. This driver is supposed
to test the full feature without other software(Ex vhost process) and hardware
dependence. ecdsa is introduced into qapi type without implementation, this may
be implemented in Q3-2022 or later. If ecdsa type definition should be added
with the implementation together, I'll remove this in next version.
[5] keyctl backend is in development, we will post this feature in Q2-2022.
keyctl backend can use hardware acceleration(Ex, Intel QAT).
Setup the full environment, tested with Intel QAT on host side, the QPS of HTTPS
increase to ~200% in a guest.
VS PCI passthrough: the most important benefit of this solution makes the VM
migratable.
v2 -> v3:
- Introduce akcipher types to qapi
- Add test/benchmark suite for akcipher class
- Seperate 'virtio_crypto: Support virtio crypto asym operation' into:
- crypto: Introduce akcipher crypto class
- virtio-crypto: Introduce RSA algorithm
v1 -> v2:
- Update virtio_crypto.h from v2 version of related kernel patch.
v1:
- Support akcipher for virtio-crypto.
- Introduce akcipher class.
- Introduce ASN1 decoder into QEMU.
- Implement RSA backend by nettle/hogweed.
Lei He (6):
qapi: crypto-akcipher: Introduce akcipher types to qapi
crypto: add ASN.1 DER decoder
crypto: Implement RSA algorithm by hogweed
crypto: Implement RSA algorithm by gcrypt
test/crypto: Add test suite for crypto akcipher

2.20.1
Introduce new akcipher crypto class 'QCryptoAkCIpher', which supports
basic asymmetric operations: encrypt, decrypt, sign and verify.
Suggested by Daniel P. Berrang?, also add autoptr cleanup for the new
class. Thanks to Daniel!

[PATCH v6 5/9] crypto: Implement RSA algorithm by hogweed
From: Lei He <helei.sig11 at bytedance.com>
Implement RSA algorithm by hogweed from nettle. Thus QEMU supports
a 'real' RSA backend to handle request from guest side. It's
important to test RSA offload case without OS & hardware requirement.

From: Lei He <helei.sig11 at bytedance.com>
Added gcryt implementation of RSA algorithm, RSA algorithm
implemented by gcrypt has a higher priority than nettle because
it supports raw padding.

2.20.1
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
