Lua Records: Support of empty answers on filterForward()

[paddg]

• Program: Authoritative
• Issue type: Feature request

Short description

Return empty answers from filterForward() for addresses in the NetmaskGroup argument, instead of 0.0.0.0 or ::0.

Usecase

We'd like to use createForward() in conjunction with filterForward(). Up to now we have answered queries for addresses outside our networks with an empty answer. filterForward() responds with 0.0.0.0 or ::0 by default in this case. Since we do not want to change the usual behavior of our DNS servers, it would be nice if we could continue do so.

Description

In addition, filterForward() should accept '' (empty string) as the fallback argument and it should respond with a empty answer in this case.

@Habbie, do you think this feature will make it into a 4.8 maintenance release? We'd be very happy.

[Habbie]

I'll see what I can do, and otherwise I hope we can ship some fun new features in a 4.9 alpha soon. I'll try to keep them backportable :)

[paddg]

Is this still planned for 4.9? I ask because no new milestone was set.

[Habbie]

Oops. I'll see what I can do!
