This patchset introduces some of changes discussed on mailing list
for 22.07 release in cryptodev asym.

Key changes:

- It fixes API for RSA (expescially signature paddings)
- Adds Elliptic-Curve Diffie-Hellman
- Removes LIST_END enumerators (ABI issue - supressed asym_xform)
- Adds Eliiptic-Curve point verification (DH verification - but will be used only for EC)
- Adds RSA missing padding fields.
- Adds asym op flags
- Fixes many API comments (like EC curves)

Commits are grouped by functionality, and mostly independent.

- EC enum was renamed to rte_crypto_curve_id.
Elliptic curve enum name is incorrectly associated
with group (it comes from current tls registry name).
- Clarified comments about TLS deprecation
Some curves included are deprecated with TLS 1.3.
Comments to address it were added.
- Clarified FFDH groups usage.
Elliptic curves IDs in TLS are in the same registry
as FFDH. Cryptodev does not assign specific groups, and
if specific groups would be assigned to enum it cannot be
TLS SupportedGroups registry as it would conflict with
other protocols like IPSec.
- Added IANA reference.
Only few selected curves are included in previously
referenced rfc8422. IANA reference is added instead.
- Removed UNKNOWN ec group.
There is no default value, and there is no UNKNOWN
elliptic curve.

- Removed LIST_END enumerators from asymmetric crypto API.
Adding new enum entries would require moving
LIST_END down, therefore changing its assigned number.
This would cause problems to ABI stability, so these
enums were removed.

- Reduced number of comments in asymmetric xform.
Information describing basic functionality of well known
algorithms are unnecessary.
- Added information about data memory lifetime.
It was specified how user should work with private data,
and it is user's responsability to clear it.
- Removed NONE asymetric xform.

- separated key exchange enum.
Key exchange and asymmetric crypto operations like signatures,
encryption/decryption should not share same operation enum as
its use cases are unrelated and mutually exclusive.
Therefore op_type was separate into:
1) operation type
2) key exchange operation type

- removed unnecessary zero assignement in rsa padding enum.
Even it is set correctly it should be made consistent with
other enums in cryptodev. Therefore assignement to zero was
removed.

Hellman ephemeral key.
DH and DSA integration allowed to use
ephemeral keys for random integer but not for private keys.

- removed asymnetric crypto xform next field.
Rationale behind having chaining in symmetric crypto
was a fact that encryption and authentication are usually
done on the same set of data independent of algorithm.
HW usually will be able to handle it in one PCI call.
In asymmetric there is no such relation between algorithms,
therefore next field would be useless.

- Moved dh operation type to dh operation struct.
Operation type (PUBLIC_KEY_GENERATION, SHARED_SECRET) should
be free to choose for any operation. One xform/session should
be enough to perform both DH operations, if op_type would be xform
member, session would have to be to be created twice for the same
group. Similar problem would be observed in sessionless case.
Additionally, it will help extend DH to support Elliptic Curves.

- changed order of Diffie-Hellman struct fields.
Now order of Diffie-Hellman struct members corresponds
to order of operation in Diffie-Hellman key exchange.

- added elliptic curve Diffie-Hellman parameters.
Point multiplication allows the user to process every phase of
ECDH, but for phase 1, user should not really care about the generator.
The user does not even need to know what the generator looks like,
therefore setting ec xform would make this work.

- Added key exchange public key verify option.
For some elliptic curves public point in DH exchange
needs to be checked, if it lays on the curve.
Modular exponentiation needs certain checks as well, though
mathematically much easier.
This commit adds verify option to asym_op operations.

- move RSA padding into separate struct.
More padding members should be added into padding,
therefore having separate struct for padding parameters will
make this more readable.

- added salt length and optional label.
Common parameters to PSS and OAEP padding for RSA.
- Fixed hash API in RSA padding.
Now it is specified how hash should be used with
particular RSA padding modes.

- reduced rsa struct to only necessary fields.
RSA operation is generally used with one input and one output.
One exception for this is signature verification, when RSA verify
called, both message and signature are inputs, but there is no rsa
output except for op status.

- added flags to rte_crypto_asym_op struct.
It may be shared between different algorithms.
- added Diffie-Hellman padding flags.
Diffie-Hellman padding is used in certain protocols,
in others, leading zero bytes need to be stripped.
Even same protocol may use a different approach - most
glaring example is TLS1.2 - TLS1.3.
For ease of use, and to avoid additional copy
on certain occasions, driver should be able to return both.

- clarified usage of private key in Diffie-Hellman.
CSRNG capable device should generate private key and then
use it for public key generation.

Individual patches must compile.
There are multiple patches which needs to be combined.
6,7,8 should be a single patch or else compilation will be broken

2,3 should also be combined.

[Arek] - I will send v2 then, and I will fix all technical issues. Please verify if you are fine with changes proposed,. Most of these changes were already proposed in previous patches and in RFCs with no or minor problems found. Second patchset I would like to send contains capability changes and montgormery/Edwards curvers (would be good to have this in this release).

This function is later added with new way of handling it, but in v2 I will squash this changes into one so it will not be removed.

Why are these SET/GET macros needed?
Is the following not sufficient

#define RTE_CRYPTO_ASYM_FLAG_PUB_KEY_NO_PADDING   RTE_BIT32(0)
#define RTE_CRYPTO_ASYM_FLAG_SHARED_KEY_NO_PADDING  RTE_BIT32(1)

op->flags |= RTE_CRYPTO_ASYM_FLAG_PUB_KEY_NO_PADDING;

I believe removing this is not a good idea. As stated, it will help in

Please check documentation "doc/guides/prog_guide/cryptodev_lib.rst"
Not all asymmetric crypto xforms are supported for chaining. Currently supported
asymmetric crypto chaining is Diffie-Hellman private key generation followed by
public generation. Also, currently API does not support chaining of symmetric and
asymmetric crypto xforms.

I believe this should be a separate patch. Right?

Drop the word padding.

BTW, can this be a union for label and saltlen?

I am not sure if this is the correct renaming of fields.

You are changing the name of message -> input and 
Cipher and sign -> output/message union. Right?

I believe this would impact the existing applications and 
Would create confusion as the message was used for input and now it is 
In union with output.

The logic listed here is looking very complex.
Please simplify it. Can you try adding comments in the description of struct
Instead of individual fields.

Does it mean if padding.type = RTE_CRYPTO_RSA_PADDING_PKCS1_5 or RTE_CRYPTO_RSA_PADDING_PSS  and if RTE_CRYPTO_RSA_FLAG_PT flag is set

[Arek] - it is similar issue as in DSA/ECDSA 'k'. Or we will add some PMD flag to determine if PMD is CSRNG capable or it will be stated in PMD .rst file. If device does not support random, packet will be rejected (send to response queue with NOT_PROCESSED). This comment should probably be added.

[Arek] And why do chaining when this can be done even with one bit flag.

Also, currently API does not support chaining of

[Arek] - This is one unlikely scenario to combine symmetric and asymmetric. One I can think of was once proposed DH + DSA integration for random number. But not much else, although we can keep it around for a while.

[Arek] - additionally there is still an option to split it into DH_PARAM, ECDH_PARAM, x25519. For secp and Edwards/Montgomery it should be ok with current approach but for SM2 we may need new struct.

[Arek] - Well, this depends on protocol, usually it is size check for FFDH and zero check for x25519/448. Not sure how much information should be provided here.

[Arek] - now it aligns with RSA RFC. Both current names comes from the OpenSSL EVP_MD naming, in my rfc initially mgf1md was changed too into:
+enum rte_crypto_mgf {
+	RTE_CRYPTO_MGF_DEFAULT,
+	/**< Default mask generation function */
+	RTE_CRYPTO_MGF_MGF1_SHA1,
+	/**< MGF1 function with SHA1 hash algorithm */
But we do not need to be that conformant with the standard I think, so I have left it out.
As for names it may be 'md' as well, every name is ok if is not excessively long.

[Arek] - Yes, this will impact current apps. And yes, message may be confusing.
But main question, is there consensus for the Input - Output approach in RSA? If not I will drop it from v2.
If so, in case SIGNATURE_VERIFY and PADDING_NONE decrypted signature should be placed in message or cipher with no further PMD involvement.

[Arek] - maybe this is not that important but could not we have asym_algorithm instead of xform_type? There is not ECDSA/ECPM xform at all.

Converting everything to asym algo may not be good. As they have different xforms
And different type of operations.
May be we could split into xform type and algo similar to symmetric crypto?

I can understand we cannot specify everything here.
How about adding in documentation a section to give details?

I believe we need better documentation for asymmetric cryptography.

If we are removing it, then documentation should be in sync.

Yes it is highly unlikely to use this combination.

I believe this can be covered in the capability patch that you are working on.

[Arek] - actually I came with another idea.
I have added ECDH param, VERIFY is valid only for ecdh_op and verify is:
RTE_CRYPTO_ASYM_KE_EC_PUBLIC_KEY_VERIFY, so it is not included in dh_op_param.
I doubt there will be any hw acceleration for anything else than EC point verification + I doubt there will be 4 steps verification (that's why I have not included it in flags). I have spilt DH into DH and ECDH, as it probably will be easier when adding sm2 key exchange (instead of extending union fields)

And we definitely need better tests, I have removed part of dh code from openssl pmd at random some time ago and all DH tests still passed!
I have added key exchange tests some time ago, this could be good start, I have v2 for ECDH too.

[Arek] - although, we may keep it for now, I am not dropping it in v2. DH priv + pub can be done with priv_key.len = 0 -> similar as 'k' in ecdsa when k.data = NULL.
But I do not see any situation for now it will be  useful, it may be dropped later if not application found.

[Anoob] We may need this support when we add EdDSA support. That would involve a asymmetric operation after hash is generated (symmetric). 
https://en.wikipedia.org/wiki/EdDSA#Ed25519

And, asymmetric chaining may become useful when we have PMDs capable of doing more operations together (like the case with EdDSA). So my preference would be to retain the 'next' field in asym crypto xform.

[Arek] - that is very good point, however to implement EdDSA as chaining would mean that:
- we need to implement EdDSA internals in DPDK
- and EdDSA (in hash option, where actually picking hash would have sense) is not one hash but multiple hash operation, so we would have to had multiple chaining with operations in between
- and we would have to compute R and S separately.
- If PMD does not support one-pass EdDSA - well this is something that should definitely discuss, but having any crypto internals in DPDK is not probably an option?

[Arek] - additionally if EdDSAhash one-pass used it is enough to have field with hash, an that's all - only information needed.
Normally EdDSA hash is fixed to SHA256 or BLAKE but for EdDSAhash option there is one additional hash - so enum in Ed struct should be enough.

[Anoob] I'm also not clear about what would be the right abstraction. As you described for EdDSA, it can be just a flag. But we may need to revisit this when we add such kind of algos. So my suggestion was to not remove 'next' field just yet. We can revisit this sometime later.

Thanks for agreeing to the suggestion and keeping the field.

[Arek] - I considered few Ed options:
- or to have
Ed25519_op, Ed448_op,
- or 
EdDSA with
Curve_is = curve25519 (29) | curve448 (30)

By default hash algorithms are SHA2-56 and BLAKE accordingly.
But for preHash Ed there would be hash field:
Hash = [ rte_crypto_auth ]

/* When preHash (PH(M)) used this field is obligatory etc... */
