This patch series add support for asymmetric crypto in DPDK
librte_cryptodev framework along with unit test, PMD and
documentation updates and addresses patch apply failure
raised on asym crypto v1 patch series:
https://dpdk.org/dev/patchwork/patch/36575/
https://dpdk.org/dev/patchwork/patch/36576/
https://dpdk.org/dev/patchwork/patch/36577/
And, unit test and PMD patch series:
https://dpdk.org/dev/patchwork/patch/36928/
https://dpdk.org/dev/patchwork/patch/36929/
https://dpdk.org/dev/patchwork/patch/36930/
Key changes from PATCH v1:
- resolve git apply patch error on patch id 36575
- resolve git apply patch error on patch id 36929
Key changes from RFCv1 include:
- removal of dedicated sym and asym qp setup,
- remove asym qp count and attach/detach_session apis
- re-org xforms params for deffie-hellman to allow
public key and optional private key generations
- move elliptic curve changes into another separate patch/patch series
This patch series is divided in to following categories:
1. library patches with asymmetric API, xform and capability
definitions
2. Unit test case addition
3. Openssl PMD changes with asymmetric crypto support
4. Programmer Guide updates with asymmetric description
TBD:
- add elliptic curve support
- rename of existing session_configure/clear APIs to
sym_session_configure/clear/init APIs
It is based on review discussion on RFC v1 asym crypto patch
http://dpdk.org/patch/34308.
RFC v1 patch http://dpdk.org/patch/34308 is further a derivative of
earlier reviewed RFC v2 patch series:
http://dpdk.org/dev/patchwork/patch/24245/
http://dpdk.org/dev/patchwork/patch/24246/
http://dpdk.org/dev/patchwork/patch/24247/

Extend DPDK librte_cryptodev to:
- define asym op type in rte_crypto_op_type and associated
op pool create/alloc APIs
- define asym session and associated session APIs
If PMD shows in its feature flag that it supports both sym and
asym then it must support those on all its qps.
If PMD support both but internally has hw with dedicated qp for
each service then it *can* split itself into *symmetric only and
asymmetric only PMD instances*.
List of TBDs:
- change PMD ops session_get_size, session_configure, session_clear
to sym_session_* APIs
- change external get_session_private_size to sym_get_session_*
- per-service stats update
Open for consideration:
- sessionless asymmetric ops.
current proposal only define session based operations.
Changes from PATCHv1
- resolve new line error in librte_cryptodev/rte_cryptodev_version.map

Add unit test case to test openssl PMD asym crypto
operations. Test case invoke asymmetric operation on DPDK
Openssl PMD and cross-verify results via Openssl SW library.
Tests have been verified with openssl 1.0.2m release.
Tested for:
* RSA Encrypt, Decrypt, Sign and Verify using pre-defined
test vectors
* Modular Inversion and Exponentiation using pre-defined
test vectors
* Deiffie-Hellman Public key generation using pre-defined
private key and dynamically generated test vectors
* Deffie-hellman private key generation using dynamically
generated test vectors
* Deffie-hellman private and public key pair generation
using xform chain and using dynamically generated test
vectors
* Deffie-hellman shared secret compute using dynamically
generated test vectors
* DSA Sign and Verification
Deffie-hellman testcases use run-time generated test params,
thus may take some time for execution.

Asymmetric Cryptography
-----------------------
-Asymmetric functionality is currently not supported by the cryptodev API.
+The cryptodev library currently provides support for the following asymmetric
+Crypto operations; RSA, Modular exponentiation and inversion, Deffie-hellman
+public and/or private key generation and shared secret compute, DSA Signature
+generation and verification.
+
+Session and Session Management
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Sessions are used in asymmetric cryptographic processing to store the immutable
+data defined in asymmetric cryptographic transform which is further used in the
+operation processing. Sessions typically stores information, such as, public
+and private key information or domain params or prime modulus data i.e. immutable
+across data sets. Crypto sessions cache this immutable data in a optimal way for the
+underlying PMD and this allows further acceleration of the offload of Crypto workloads.
+
+Like symmetric, the Crypto device framework provides APIs to allocate and initizalize
+asymmetric sessions for crypto devices, where sessions are mempool objects.
+It is the application's responsibility to create and manage the session mempools.
+Application using both symmetric and asymmetric sessions should allocate and maintain
+different sessions pools for each type.
+
+An application can use ``rte_cryptodev_get_asym_session_private_size()`` to
+get the private size of asymmetric session on a given crypto device. This
+function would allow an application to calculate the max device asymmetric
+session size of all crypto devices to create a single session mempool.
+If instead an application creates multiple asymmetric session mempools,
+the Crypto device framework also provides ``rte_cryptodev_get_header_session_size()`` to get
+the size of an uninitialized session.
+
+Once the session mempools have been created, ``rte_cryptodev_asym_session_create()``
+is used to allocate an uninitialized asymmetric session from the given mempool.
+The session then must be initialized using ``rte_cryptodev_asym_session_init()``
+for each of the required crypto devices. An asymmetric transform chain
+is used to specify the operation and its parameters. See the section below for
+details on transforms.
+
+When a session is no longer used, user must call ``rte_cryptodev_asym_session_clear()``
+for each of the crypto devices that are using the session, to free all driver
+private asymmetric session data. Once this is done, session should be freed using
+``rte_cryptodev_asym_session_free()`` which returns them to their mempool.
+
+Asymmetric Sessionless Support
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Currently asymmetric crypto framework does not support sessionless.
+
+Transforms and Transform Chaining
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Asymmetric Crypto transforms (``rte_crypto_asym_xform``) are the mechanism used
+to specify the details of the asymmetric Crypto operation. Next pointer within
+xform allows transform to be chained together. Also it is important to note that
+the order in which the transforms are passed indicates the order of the chaining.
+
+Not all asymmetric crypto xforms are supported for chaining. Currently supported
+asymmetric crypto chaining is Deffie-hellman private key generation followed by
+public generation. Also, currently API does not support chaining of symmetric and
+asymmetric crypto xfroms.
+
+Each xform defines specific asymmetric crypto algo. Currently supported are:
+* RSA
+* Modular operations (Exponentiation and Inverse)
+* Deffie-hellman
+* DSA
+* None - special case where PMD may support a passthrough mode. More for diagonistic purpose

+

+ /**< DSA xform parameters */
+ };
+ };
+
+Asymmetric Operations
+~~~~~~~~~~~~~~~~~~~~~
+
+The asymmetric Crypto operation structure contains all the mutable data relating
+to asymmetric cryptographic processing on an input data buffer. It uses either
+RSA, Modular, Deffie-hellman or DSA operations depending upon session it is attached
+to.
+
+Every operation must carry a valid session handle which further carries information
+on xform or xform-chain to be performed on op. Every xform type defines its own set
+of opertational params in their respective rte_crypto_xxx_op_param struct. Depending
+on xform information within session, PMD picks up and process respective op_param
+struct.
+Unlike symmetric, asymmetric operations do not use mbufs for input/output.
+They operate on data buffer of type ``rte_crypto_param``.

+using 1024-bit modulus length using openssl PMD available in DPDK (performing other
+crypto operations is similar except change to respective op and xform setup).

As already discussed in separate mails, I will defer these patches to 18.08,
targetting an earlier merge for that release.

Thanks for info. However, assume API name change is not blocker for spec to be in 18.08. So, I planned to do it at later stage after spec get stabilize and accepted.
Do you have any other thoughts to it?

[Fiona] Are you introducing a bug here?
The fn expects a void **
Also this will need rebasing - the latest code has an extra byte.

[Fiona] Is it necessary to have xform_type in both above structures?
Seems like duplication. Or would it be better if both are combined into 1 struct?

Any modifications to the API, including name changes, require a deprecation notice.
Making this change will break the compilation of all the apps using it.
What I would suggest is renaming the function and creating a wrapper with the current name,
calling the new function, and marking it as rte_deprecated.
Something like:
/*
* @deprecated ...
*/
__rte_deprecated
unsigned
rte_cryptodev_get_session_private_size(...) {
return rte_cryptodev_get_sym_session_private_size(...);
}
This way, we can give users time to change to the new API, without breaking directly the code.
Thanks,
Pablo

[Fiona] What was your rationale for adding this into the openssl PMD vs creating a new openssl_asym PMD?
Will this work ok if there's a burst of ops including asym and sym operations enqueued to the same qp?

[Shally] Openssl supports both. Also, it provided as good example to demonstrate use-case to apps/PMDs that can support both.
>Will this work ok if there's a burst of ops including asym and sym operations enqueued to the same qp?
[Shally] first theoretical limitation in spec is not to send mix sym+asym to a single qp. Same limitation, I brought out in DPDK India summit talk as well.
Thus, It is not proof-concepted in this patch of PMD. If required, a testcase can be added in subsequent versions as it is kind of advance test on openssl PMD and spec.
