[Touch-packages] [Bug 1803203] Re: Support preferred_lft for IPv6 addresses
@rlaager I've started a PR discussion on Netplan.io's Github with your proposed changes as they seemed the best way forward for now. I don't expect this to get merged right away, as the maintainers might want to discuss the changes to the schema in further detail. In any case, this should at least start a discussion on getting this fixed in upstream netplan. https://github.com/CanonicalLtd/netplan/pull/89 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1803203 Title: Support preferred_lft for IPv6 addresses Status in netplan: New Status in netplan.io package in Ubuntu: In Progress Status in systemd package in Ubuntu: Fix Released Bug description: There doesn't currently seem to be any way to set the preferred_lft of an IPv6 address.

[Touch-packages] [Bug 1803203] Re: Support preferred_lft for IPv6 addresses
Currently, addresses is a "sequence of scalars" (aka a list). Here is
the example from the Netplan reference you quoted:
addresses: [192.168.14.2/24, "2001:1::1/64"]
This can, currently, also be written in this form (quotes optional):
addresses:
- 192.168.14.2/24
- "2001:1::1/64"
I actually prefer the latter form, so that's what I use today.
In YAML generally (not necessarily Netplan specifically), I think the
obvious extension would be to support dictionaries in addition to
scalars, for the addresses. That would allow for this type of extension:
addresses:
- 192.168.14.2/24
- "2001:1::1/64":
lifetime: 0
other: x
future: y
parameters: z
If you really want the flattened form, it would be:
addresses: [192.168.14.2/24, "2001:1::1/64": {lifetime: 0}]
This is a clean extension from the current syntax and supports other
future parameters.
Whether Netplan's YAML parser currently supports dictionaries is another
question. But this is all normal YAML. See, for example, Ansible:
https://docs.ansible.com/ansible/latest/reference_appendices/YAMLSyntax.html

[Touch-packages] [Bug 1803203] Re: Support preferred_lft for IPv6 addresses
Some notes for reference: We might actually have some trouble in expressing the Lifetime of an Address in the Netplan schema. From the Netplan Reference [0] we can see that the 'addresses:' field accepts a list of mixed IPv4 and IPv6 addresses. We can't just add a 'lifetime:' field to the schema, because then we wouldn't have a way to link that value to one of the addresses in the mixed list. I can see a few different ways to change the configuration to accommodate the lifetime change: 1) Implement a list of lifetimes, which would "follow" the list of addresses (i.e. lifetime[0] corresponds to addresses[0] and so on) 2) Modify the address syntax inside the list to allow an optional lifetime, e.g.: addresses: [127.0.0.1 (forever), "2001:1::1/64 (0)"] 3) Allow the definition of an address+lifetime mapping and use that in the 'addresses' field, e.g.: myaddr: value: 127.0.0.1 lifetime: 0 ... addresses: [ myaddr, 2001:1::1/64 ] Option 1 has the obvious problem of matching one lifetime to a list of multiple addresses. Say we want to specify a lifetime to address number K in the list, would we need to specify a lifetime for all of them? How would we "skip" default lifetimes with this approach? Option 2 has the benefit of being somewhat compatible with the current schema in the sense that if no lifetime is specified, we can keep the current behavior. I feel like it would introduce a lot of complexity in the schema parsing code to sort the addresses from the lifetime though, and this might not be something that we want in a sensitive code section. Option 3 looks very flexible, but I'm not familiar enough with the schema and its parsing code to estimate the impact that would have. I think we would need quite a few significant changes, and I'm not really sure where we would place the 'myaddr' definition in the schema either. None of the above options feel like a good way to solve the lifetime problem, but I'm not sure we have an easy way to integrate that into the current netplan schema. Perhaps someone more experienced with the Netplan schema/codebase might offer better insight on how to tackle this issue.

systemd back to bionic already supports the PreferredLifetime config param.
