SpoofAction constructor with (single-ip, options) does not work #9783

  • Program: dnsdist
  • Issue type: Bug report

Short description

Since 1.5 it should be possible to pass an options table to a SpoofAction constructor in order to set the TTL of the generated record. However this does not seem to work as expected:

dnsdist> SpoofAction("", {ttl=3600})
Error: Unable to convert parameter from table to N5boost8optionalINSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEEE> 

On the other hand supplying a list of two or more addresses plus the trailing options works fine.


  • Operating system: Linux (Gentoo)
  • Software version: 1.5.1
  • Software source: package / built from source (gcc-10.2, boost-1.74)

Steps to reproduce

  1. SpoofAction("") -> works
  2. SpoofAction("", {ttl=3600}) -> does not work
  3. SpoofAction("", "", {ttl=3600}) -> works, but with duplicated entry

Other information

I suspect the function untangling the arguments has problems distinguishing between a single string and a list of strings, here. I don't understand enough about Lua/C++ value coercion and how boost::variant works to fix this myself though.

in the docs the syntax is SpoofAction({ip|ips}[, options]), in the code it looks like SpoofAction({ip|ips}[, ip[, options]]). I wonder what the second argument is all about.

I honestly don't know because we also take a list.. Let's get rid of it for 1.6.0?

If anyone runs into this before they are on an updated version, @rgacogne pointed out this work around SpoofAction("", nil, {aa=true})
