KEYS: Implement asymmetric key type Create a key type that can be used to represent an asymmetric key type for use in appropriate cryptographic operations, such as encryption, decryption, signature generation and signature verification. The key type is "asymmetric" and can provide access to a variety of cryptographic algorithms. Possibly, this would be better as "public_key" - but that has the disadvantage that "public key" is an overloaded term.

KEYS: Generalise x509_request_asymmetric_key() Generalise x509_request_asymmetric_key(). It doesn't really have any dependencies on X.509 features as it uses generalised IDs and the public_key structs that contain data extracted from X.509. Signed-off-by: David Howells <dhowells@redhat.com>

KEYS: Implement binary asymmetric key ID handling Implement the first step in using binary key IDs for asymmetric keys rather than hex string keys. The previously added match data preparsing will be able to convert hex criterion strings into binary which can then be compared more rapidly. Further, we actually want more then one ID string per public key. The problem is that X.509 certs refer to other X.509 certs by matching Issuer + AuthKeyId to Subject + SubjKeyId, but PKCS#7 messages match against X.509 Issuer + SerialNumber. This patch just provides facilities for a later patch to make use of. Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Vivek Goyal <vgoyal@redhat.com>

KEYS: make partial key id matching as a dedicated function To avoid code duplication this patch refactors asymmetric_key_match(), making partial ID string match a separate function. This patch also implicitly fixes a bug in the code. asymmetric_key_match() allows to match the key by its subtype. But subtype matching could be undone if asymmetric_key_id(key) would return NULL. This patch first checks for matching spec and then for its value. Signed-off-by: Dmitry Kasatkin <d.kasatkin@samsung.com> Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com>

KEYS: fix "ca_keys=" partial key matching The call to asymmetric_key_hex_to_key_id() from ca_keys_setup() silently fails with -ENOMEM. Instead of dynamically allocating memory from a __setup function, this patch defines a variable and calls __asymmetric_key_hex_to_key_id(), a new helper function, directly. This bug was introduced by 'commit 46963b774d44 ("KEYS: Overhaul key identification when searching for asymmetric keys")'. Changelog: - for clarification, rename hexlen to asciihexlen in asymmetric_key_hex_to_key_id() - add size argument to __asymmetric_key_hex_to_key_id() - David Howells - inline __asymmetric_key_hex_to_key_id() - David Howells - remove duplicate strlen() calls Acked-by: David Howells <dhowells@redhat.com> Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com> Cc: stable@vger.kernel.org # 3.18

KEYS: Provide missing asymmetric key subops for new key type ops [ver #2] Provide the missing asymmetric key subops for new key type ops. This include query, encrypt, decrypt and create signature. Verify signature already exists. Also provided are accessor functions for this: int query_asymmetric_key(const struct key *key, struct kernel_pkey_query *info); int encrypt_blob(struct kernel_pkey_params *params, const void *data, void *enc); int decrypt_blob(struct kernel_pkey_params *params, const void *enc, void *data); int create_signature(struct kernel_pkey_params *params, const void *data, void *enc); The public_key_signature struct gains an encoding field to carry the encoding for verify_signature().
