From: Fan Zhang <roy.fan.zhang@intel.com>
This patch introduces the new framework to share common code between
the SW crypto PMDs that depend on the intel-ipsec-mb library.
This change helps to reduce future effort on the code maintenance and
feature updates.
The PMDs that will be added to this framework in subsequent patches are:
- AESNI MB
- AESNI GCM
- KASUMI
- SNOW3G
- ZUC
The use of these PMDs will not change, they will still be supported for
x86, and will use the same EAL args as before.
The minimum required version for the intel-ipsec-mb library is now v1.0.

Not sure if the name ipsec_mb is appropriate for a crypto PMD which
also support algos which are not specified for IPsec like ZUC/SNOW/KASUMI.
Moreover, this is a crypto PMD and not IPsec PMD.

I believe 1 instance of the ipsec_mb PMD will support only

This cannot be changed during the lifetime of the process. Right?

Yes - please treat the ipsec_mb_pmd.c/pmd_ops.c as the shared code base for these existing SW crypto PMDs based on intel-ipsec-mb library. There is no new PMD called ipsec_mb as such.
Maybe to make it less misleading we could rename the file names like so:
Ipsec_mb_pmd.c -> ipsec_mb_private.c
And similar change for ipsec_mb_pmd_ops.c and ipsec_mb_pmd_private.h
What do you think?
Thanks,

The ipsec_mb SW PMD now has multiprocess support.
The queue-pair IMB_MGR is stored in a memzone instead of being allocated
externally by the Intel IPSec MB library, when v1.1 is used.
If v1.0 is used, multi process is not supported, and allocation is
done as before.
The secondary process needs to reconfigure the queue-pair to allow for
IMB_MGR function pointers be updated.
Intel IPsec MB library version 1.1 is required for this support.

Missed to comment on first patch.
rte_ may be skipped from the internal files of the PMD.
rte_ is normally added for files which are exposed to the user.

I believe first new PMD framework should be introduced in the release note and
a sub bullet may be added to specify multi process support.

Thomas Monjalon, Pablo de Lara, Ray Kinsella
From: Piotr Bronowski <piotrx.bronowski@intel.com>
This patch removes the crypto/aesni_mb folder and gathers all
aesni-mb PMD implementation specific details into a single file,
pmd_aesni_mb.c in crypto/ipsec_mb.
Now that intel-ipsec-mb v1.0 is the minimum supported version, old
macros can be replaced with the newer macros supported by this version.
Signed-off-by: Piotr Bronowski <piotrx.bronowski@intel.com>

v3:
- Updated intel-ipsec-mb library macros.
- Fixed some formatting.
v2: Updated maintainers file.

We support more than 240 bytes of AAD. I think we can support up to 1024 bytes.
Could you change it here?

Wrong error message. This should say something like "Wrong authentication key length".
Also, the same message is present for the cipher key length, for GCM.

This patch removes the crypto/aesni_gcm folder and gathers all
aesni-gcm PMD implementation specific details into a single file,
pmd_aesni_gcm.c in the crypto/ipsec_mb folder.
A redundant check for iv length is removed.
GCM ops are stored in the queue pair for multi process support, they
are updated during queue pair setup for both primary and secondary
processes.
GCM ops are also set per lcore for the CPU crypto mode.
Signed-off-by: Piotr Bronowski <piotrx.bronowski@intel.com>
Signed-off-by: Ciara Power <ciara.power@intel.com>
---
v3:
- Moved session GCM ops to queue pair.
- Added GCM ops per lcore.
- Fixed some formatting.
v2:
- Fixed enum for GCM key length.
- Updated maintainers file.

Looks like there is a bug here. We don't need to enqueue operations back in the ring here.
We used to enqueue in the ring when crypto processing was done in enqueue, but now this is part of dequeue
and we already dequeued the operations from the ring.
As far as I know, the only enqueue operation in the ring should be done in enqueue_burst.
Thanks,
Pablo

This patch enables out-of-place auth-cipher operations where
digest should be encrypted along with the rest of raw data.
It also adds support for partially encrypted digest when using
auth-cipher operations.

+Chacha20-poly1305 Crypto Poll Mode Driver
+=========================================
+
+The Chacha20-poly1305 PMD provides poll mode crypto driver support for
+utilizing `Intel IPSec Multi-buffer library <https://github.com/01org/intel-ipsec-mb>`_.
+
+Features
+--------
+
+Chacha20-poly1305 PMD has support for:
+
+AEAD algorithms:
+
+* RTE_CRYPTO_AEAD_CHACHA20_POLY1305
+
+
+Installation
+------------
+
+To build DPDK with the Chacha20-poly1305 PMD the user is required to download
+the multi-buffer library from `here <https://github.com/01org/intel-ipsec-mb>`_
+and compile it on their user system before building DPDK.
+The latest version of the library supported by this PMD is v1.0, which
+can be downloaded from `<https://github.com/01org/intel-ipsec-mb/archive/v1.0.zip>`_.
+
+After downloading the library, the user needs to unpack and compile it
+on their system before building DPDK:
+
+.. code-block:: console
+
+ make
+ make install
+
+The library requires NASM to be built. Depending on the library version, it might
+require a minimum NASM version (e.g. v0.54 requires at least NASM 2.14).
+
+NASM is packaged for different OS. However, on some OS the version is too old,
+so a manual installation is required. In that case, NASM can be downloaded from
+`NASM website <https://www.nasm.us/pub/nasm/releasebuilds/?C=M;O=D>`_.
+Once it is downloaded, extract it and follow these steps:
+
+.. code-block:: console
+
+ ./configure
+ make
+ make install
+
+.. note::
+
+ Compilation of the Multi-Buffer library is broken when GCC < 5.0, if library <= v0.53.
+ If a lower GCC version than 5.0, the workaround proposed by the following link
+ should be used: `<https://github.com/intel/intel-ipsec-mb/issues/40>`_.
+
+As a reference, the following table shows a mapping between the past DPDK versions
+and the external crypto libraries supported by them:
+
+.. _table_zuc_versions:
+
+.. table:: DPDK and external crypto library version compatibility
+
+ ============= ================================
+ DPDK version Crypto library version
+ ============= ================================
+ 21.11+ Multi-buffer library 1.0*
+ ============= ================================
+
+\* Multi-buffer library 1.0 or newer only works for Meson but not Make build system.
+
+Initialization
+--------------
+
+In order to enable this virtual crypto PMD, user must:
+
+* Build the multi buffer library (explained in Installation section).
+
+To use the PMD in an application, user must:
+
+* Call rte_vdev_init("crypto_chacha20_poly1305") within the application.
+
+* Use --vdev="crypto_chacha20_poly1305" in the EAL options, which will call
+ rte_vdev_init() internally.
+
+The following parameters (all optional) can be provided in the previous two calls:
+
+* socket_id: Specify the socket where the memory for the device is going to be allocated
+ (by default, socket_id will be the socket where the core that is creating the PMD is running on).
+
+* max_nb_queue_pairs: Specify the maximum number of queue pairs in the device (8 by default).
+
+* max_nb_sessions: Specify the maximum number of sessions that can be created (2048 by default).
+
+Example:
+
+.. code-block:: console
+
+ --vdev="crypto_chacha20_poly1305,socket_id=0,max_nb_sessions=128"

> +
> +* Build the multi buffer library (explained in Installation section).
> +
> +To use the PMD in an application, user must:
> +
> +* Call rte_vdev_init("crypto_chacha20_poly1305") within the application.
> +
> +* Use --vdev="crypto_chacha20_poly1305" in the EAL options, which will
> call
> + rte_vdev_init() internally.
> +
> +The following parameters (all optional) can be provided in the previous two
> calls:
> +
> +* socket_id: Specify the socket where the memory for the device is going to
> be allocated
> + (by default, socket_id will be the socket where the core that is creating the
> PMD is running on).
> +
> +* max_nb_queue_pairs: Specify the maximum number of queue pairs in the
> device (8 by default).
> +
> +* max_nb_sessions: Specify the maximum number of sessions that can be
> created (2048 by default).
> +
> +Example:
> +
> +.. code-block:: console
> +
> + --vdev="crypto_chacha20_poly1305,socket_id=0,max_nb_sessions=128"

* Added PMD to support chacha20-poly1305 algorithms to IPSec_MB PMD framework.
* Test vector added for chacha20-poly1305 SGL test.
+* **Consolidated SW Crypto PMDs with IPSec_MB dependency.**
+
+ Intel SW Crypto PMDS that depend on the IPSec_MB library were
+ consolidated into a single source folder so that common code can
+ be shared between them. The usage and EAL options of these PMDs
+ are the same as before.
+ This change includes:
+
+ * AESNI_MB PMD.
+ * AESNI_GCM PMD.
+ * KASUMI PMD.
+ * SNOW3G PMD.
+ * ZUC PMD.
+ * CHACHA20-POLY1305 PMD.
+
* **Updated Marvell cnxk crypto PMD.**
* Added AES-CBC SHA1-HMAC support in lookaside protocol (IPsec) for CN10K.
