[PATCH v11 09/10] x509: Add OID for NIST P384 and extend parser for it

[Stefan Berger]

From: Saulo Alessandre <saulo.alessan...@tse.jus.br>

Prepare the x509 parser to accept NIST P384 certificates and add the
OID for ansip384r1, which is the identifier for NIST P384.

Summary of changes:

* crypto/asymmetric_keys/x509_cert_parser.c
  - prepare x509 parser to load NIST P384

* include/linux/oid_registry.h
  - add OID_ansip384r1

Signed-off-by: Saulo Alessandre <saulo.alessan...@tse.jus.br>
Tested-by: Stefan Berger <stef...@linux.ibm.com>

v10->v11:
 - renamed OID_id_secp384r1 to OID_id_ansip384r1 (spec name)
