2022-10-08firewall: T4612: Support arbitrary netmasksRain
Add support for arbitrary netmasks on source/destination addresses in firewall rules. This is particularly useful with DHCPv6-PD when the delegated prefix changes periodically.

2022-09-22xml: T4698: validating a range must be explicitly enabled in the validatorChristian Poessinger
This extends commit 28573ffe4f ("xml: T4698: drop validator name="range" and replace it with numeric"). The first version allowed both a range and discrete numbers to be validated by the numeric validator. This had a flaw as both 22 and 22-30 were valid at the same time. The generic "port-number.xml.i" building block only allows a discrete number. Now if a user set port 22-30 for e.g. SSH the daemon did no longer start. This is why range validation must be explicitly enabled.

2022-09-16xml: T4698: drop validator name="range" and replace it with numericChristian Poessinger
After T4669 added support for range validation to the OCaml validator there is no need to keep the slow Python validator in place. Raplace all occurances of <validator name="range" argument="--min=1 --max=65535"/> with <validator name="numeric" argument="--range 1-65535"/>.

2022-08-30firewall: T4655: implement XML defaultValue for name and ipv6-nameChristian Poessinger
This extends the implementation of commit 0cc7e0a49094 ("firewall: T4655: Fix default action 'drop' for the firewall") in a way that we can now also use the XML <defaultValue> node under "firewall name" and "firewall ipv6-name". This is a much cleaner approach which also adds the default value automatically to the CLIs completion helper ("?").

If a parameter is required is determined from the Python string on commit. This "indicator" is not used consistently and sometimes missing, or added where it is not required anymore due to Python script improvement/rewrite.

2022-02-24scripts: T4269: node.def generator should automatically add default valuesChristian Poessinger
Since introducing the XML <defaultValue> node it was common, but redundant, practice to also add a help string indicating which value would be used as default if the node is unset. This makes no sense b/c it's duplicated code/value/characters and prone to error. The node.def scripts should be extended to automatically render the appropriate default value into the CLI help string. For e.g. SSH the current PoC renders: $ cat templates-cfg/service/ssh/port/node.def multi: type: txt help: Port for SSH service (default: 22) val_help: u32:1-65535; Numeric IP port ... Not all subsystems are already migrated to get_config_dict() and make use of the defaults() call - those subsystems need to be migrated, first before the new default is added to the CLI help.
