RFC 9249, "A YANG Data Model for NTP", July 2022

Source of RFC: ntp (int)

Errata ID: 7401
Status: Held for Document Update
Type: Technical

Section 8 says:

  identity hmac-sha-256 {
    description
      "HMAC-SHA-256 authentication algorithm";
    reference
      "SHS: Secure Hash Standard (SHS) (FIPS PUB 180-4)";
  }

  identity hmac-sha-384 {
    description
      "HMAC-SHA-384 authentication algorithm";
    reference
      "SHS: Secure Hash Standard (SHS) (FIPS PUB 180-4)";
  }

  identity hmac-sha-512 {
    description
      "HMAC-SHA-512 authentication algorithm";
    reference
      "SHS: Secure Hash Standard (SHS) (FIPS PUB 180-4)";
  }

It should say:

  identity hmac-sha-256 {
    base crypto-algorithm;
    description
      "HMAC-SHA-256 authentication algorithm";
    reference
      "SHS: Secure Hash Standard (SHS) (FIPS PUB 180-4)";
  }

  identity hmac-sha-384 {
    base crypto-algorithm;
    description
      "HMAC-SHA-384 authentication algorithm";
    reference
      "SHS: Secure Hash Standard (SHS) (FIPS PUB 180-4)";
  }

  identity hmac-sha-512 {
    base crypto-algorithm;
    description
      "HMAC-SHA-512 authentication algorithm";
    reference
      "SHS: Secure Hash Standard (SHS) (FIPS PUB 180-4)";
  }

Notes:

The identity definitions of "hmac-sha-256", "hmac-sha-384" and "hmac-sha-512" lack the "base crypto-algorithm;" statement and therefore basically cannot be used in the scope of ietf-ntp@2022-07-05.yang.
