Describe the bug Stork allows the creation of reservations with just a mac address and client class but the reservation does not show up in the host reservation list.

To Reproduce Steps to reproduce the behavior:

  1. Install BIND9, Kea, Stork (which versions?) and run them with the following configs: '...'
  2. I do the following: ...
  3. A device in my network does the following: ...
  4. Kea/BIND9 server does the following: ...
  5. Stork does the following: ...

Expected behavior A clear and concise description of what you expected to happen: The Stork is supposed to report/do A, but didn't or did B instead.

Environment:

  • Kea version: 2.5.6 isc20240226130228 deb linked with: log4cplus 2.0.5 OpenSSL 3.0.2 15 Mar 2022 database: MySQL backend 21.0, library 8.0.36 PostgreSQL backend 20.0, library 140011 Memfile backend 3.0

  • Stork: 1.15.0

  • OS: Ubuntu 22.04.4 LTS x86_64

  • Kea: "hooks-libraries": [ { "library": "/usr/lib/x86_64-linux-gnu/kea/hooks/libdhcp_stat_cmds.so" }, { "library": "/usr/lib/x86_64-linux-gnu/kea/hooks/libdhcp_lease_cmds.so" }, { "library": "/usr/lib/x86_64-linux-gnu/kea/hooks/libdhcp_pgsql_cb.so" }, { "library": "/usr/lib/x86_64-linux-gnu/kea/hooks/libdhcp_host_cmds.so" }

after the reservation is added the reservation list in stork does not show the mac address or hostname

*Describe the solution you'd like Reservations without an assigned IP address should show the hostname and mac address in the reservation list.

Additional context We use small DHCP pools of 20 or so addresses so handle mobile devices that are occasionally connected to the network. We managed this with isc-dhcpd previously by using global reservations with just a mac address. It looks like in isc-kea a mac address and a resource are required and my understanding is that a client class counts as a resource so the reservation should be valid. Instead of global reservations we are now using per subnet reservations.

Funding its development Kea is run by ISC, which is a small non-profit organization without any government funding or any permanent sponsorship organizations. Are you able and willing to participate financially in the development costs? Yes this is a possibility

Participating in development Are you willing to participate in the feature development? ISC team always tries to make a feature as generic as possible, so it can be used in wide variety of situations. That means the proposed solution may be a bit different that you initially thought. Are you willing to take part in the design discussions? Are you willing to test an unreleased engineering code? Yes i am willing to participate in development.

Contacting you How can ISC reach you to discuss this matter further? If you do not specify any means such as e-mail, jabber id or a telephone, we may send you a message on github with questions when we have them.
