Change format of dhcp_subnets to be a dict

Top level key is now subnet CIDR, rather than a list containing dicts,
where subnet is a sub-key, so better structured

- Update to pass more modern ansible-lint
- Fix galaxy info
- Format filter plugin w/black
- BSD fixes - paths, listening IP for tftpd server

dhcpd

Installs/configure a DHCP server and TFTP server

A few assumptions are made by this role:

  • If routers is not set in the subnet dictionary (within dhcpd_subnets), then the first usable address is set as the router.
  • If routers is set and has a list of IP addresses as a part of the rfc3442routes key, RFC3442 classless static routes (option 121) will be added in addition to the standard routers (option 3)

Configuration docs

dhcpd - ISC's docs:

tftpd - Documentation is scarce. Upstream source repo:

Also supports OpenBSD dhcpd (fork of ISC) and tftpd (BSD).

Requirements

Minimum ansible version: 2.9.5

Example Playbook

- hosts: all
  vars:
    dhcpd_interfaces:
      - eth0
    dhcpd_subnets:
      "192.168.0.1/24":
        range: "192.168.0.128/25"
        dns_servers:
          - "192.168.0.1"
          - "192.168.0.2"
        dns_search:
          - "example.com"
        tftpd_server: "192.168.0.1"
        hosts:
          - name: "dns"
            ip_addr: "192.168.0.2"
            mac_addr: "a1:b2:c3:d4:e5:f6"
        routers:
          - ip: "192.168.0.1"
  roles:
    - dhcpd

ToDo

Add classless static route support for OpenBSD - see dhcp-options(5) on that system.
