The module version is unlikely to be updated, use kernel version should be

This patchset changes akcipher API to support ECDSA style signature
verification, augments x509 parser to make it work with EC-RDSA certificates,
and, finally, implements EC-RDSA (GOST 34.10) signature verification and its
integration with IMA.
Changes since RFC (v1-v4):
- akcipher set_max_size,
ecc.c have algorithms that could be used togeter by ecdh and ecrdsa.
Make it separate module. Add CRYPTO_ECC into Kconfig. EXPORT_SYMBOL and
document to what seems appropriate. Move structs ecc_point and ecc_curve
from ecc_curve_defs.h into ecc.h.

Previous akcipher .verify() just `decrypts' (using RSA encrypt which is
using public key) signature to uncover message hash, which was then
compared in upper level public_key_verify_signature() with the expected
hash value, which itself was never passed into verify().
This approach was
Allow to use EC-RDSA signatures for IMA by determining signature type by
the hash algorithm name. This works good for EC-RDSA since Streebog and
EC-RDSA should always be used together.

Add Elliptic Curve Russian Digital Signature Algorithm (GOST R
34.10-2012, RFC 7091, ISO/IEC 14888-3) is one of the Russian (and since
2018 the CIS countries) cryptographic standard algorithms (called GOST
algorithms). Only signature verification is supported, with intent to be
used in the IMA.
Some public key algorithms (like EC-DSA) keep in parameters field
important data such as digest and curve OIDs (possibly more for
different EC-DSA variants). Thus, just setting a public key (as
for RSA) is not enough.
Introduce set_params() callback for akcipher which will be used to
pass BER
In preparation for new akcipher verify call remove sign/verify callbacks
from RSA backends and make PKCS1 driver call encrypt/decrypt instead.
This also complies with the well-known idea that raw RSA should never be
used for sign/verify. It only should be used with proper padding scheme

Hi Guido.
Thanks for this patch.
See below for some review feedback.
The driver includes the "allpixelson_set" debugfs feature.
Is this a debug leftover, or is there a real need for this?
If this is a debug feature that is no logner needed then no
need to add it to the mainline driver.
