[dnsdist] Editing TTLs for spoofed responses

[Holger Hoffstätte]

Hi,

I'm successfully increasing the minimum TTL for NOERROR responses with unreasonably
small values:

   local function checkTTL(dnsResponse)
     if dnsResponse.rcode == DNSRCode.NOERROR then
       dnsResponse:editTTLs(minTTL)
     end
     return DNSResponseAction.None
   end

and registering this function via:

   addResponseAction(AllRule(), LuaResponseAction(checkTTL))

This works fine for values returned from upstream servers, but not for
hosts returned via SpoofAction, which consistently default to 60 seconds.
Are SpoofedActions not routed through the regular request/response loop?
If they are, how can I intercept them?

Sorry if this is a dumb question - I'm certain I'm doing something wrong,
I just don't know what it is.. :)

Thanks,
Holger
