[4/5] crypto: ecdsa - Move X9.62 signature decoding into template

Commit Message

Unlike the rsa driver, which separates signature decoding and
signature verification into two steps, the ecdsa driver does both in one.

This restricts users to the one signature format currently supported
(X9.62) and prevents addition of others such as P1363, which is needed
by the forthcoming SPDM library (Security Protocol and Data Model) for
PCI device authentication.

Per Herbert's suggestion, change ecdsa to use a "raw" signature encoding
and then implement X9.62 and P1363 as templates which convert their
respective encodings to the raw one.  One may then specify
"x962(ecdsa-nist-XXX)" or "p1363(ecdsa-nist-XXX)" to pick the encoding.

The present commit moves X9.62 decoding to a template.  A separate
commit is going to introduce another template for P1363 decoding.

The ecdsa driver internally represents a signature as two u64 arrays of
size ECC_MAX_BYTES.  This appears to be the most natural choice for the
raw format as it can directly be used for verification without having to
further decode signature data or copy it around.

Repurpose all the existing test vectors for "x962(ecdsa-nist-XXX)" and
create a duplicate of them to test the raw encoding.

Assuming previous musing correct middle test isn't needed.
Maybe want to keep it though. Up to you.

Seems more readable to me.

I'd rather see a separate error path even if it's a little more code.

	if (err)
		goto err_free_inst;

	return 0;

err_free_inst:
	ecdsa_x862_free(inst)

The kernel wouldn't crash in the !vlen case because
ecc_digits_from_bytes() can cope with a zero length argument.

However an integer ASN.1 tag with zero length would be illegal I think.
The integer R or S could be very short, but ought to be at least 1 byte
long.  asn1_decoder.c does not seem to error out on zero length,
I assume that would be legal at least for *some* tags.

So it does seem prudent to keep the !vlen check.

I'm aware that it looks unusual but in the crypto subsystem
it appears to be a fairly common pattern, so I followed it
to blend in:

  First set the return variable to an error code,
  then check for an error condition followed by goto.

See e.g.:

  __crypto_register_alg() in crypto/algapi.c
  software_key_eds_op() in crypto/asymmetric_keys/public_key.c
  x509_get_sig_params() in crypto/asymmetric_keys/x509_public_key.c
  x509_check_for_self_signed() in crypto/asymmetric_keys/x509_public_key.c

It seems all the existing crypto_templates uniformly follow that
pattern of jumping to an "err_free_inst" label in the
*_register_instance() error path:

$ git grep -C 4 "err_free_inst:" -- crypto/

It seemed unwise to go against the current, so I followed the
existing pattern.  Upstream diplomacy. ;)

Thanks,

Lukas
