NAME¶

nvme_insert_tls_key_compat - Derive and insert TLS key

SYNOPSIS¶

long nvme_insert_tls_key_compat (const char *keyring , const char *key_type , const char *hostnqn , const char *subsysnqn , int version , int hmac , unsigned char *configured_key , int key_len );

ARGUMENTS¶

keyring

Keyring to use

key_type

Type of the resulting key

hostnqn

Host NVMe Qualified Name

subsysnqn

Subsystem NVMe Qualified Name

version

Key version to use

hmac

HMAC algorithm

configured_key

Configured key data to derive the key from

key_len

Length of configured_key

DESCRIPTION¶

Derives a 'retained' TLS key as specified in NVMe TCP 1.0a (if version s set to '0') or NVMe TP8028 (if version is set to '1) and stores it as type key_type in the keyring specified by keyring. This version differs from nvme_insert_tls_key_versioned in that it uses the original implementation for HKDF Expand-Label which does not prefix the 'info' and 'label' strings with the length.

RETURN¶

The key serial number if the key could be inserted into the keyring or 0 with errno otherwise.
