Hi Florian,
Thank you for letting me know, I checked golang unix package and I did not find definition for NFTNL_UDATA_RULE_COMMENT. That explains why I did not use it.
Could you please point me where UDATA relate types and subtypes are defined, so I could replicate them in go.
Thank you
Serguei

Then you are using it wrong :-)
Userdata is structured, its not used only for comments.
Which userdata are you referring to? We have this for
rules, sets, and elements.

As far as I can see what you want is already implemented, for example
rule comments live in NFTNL_UDATA_RULE_COMMENT sub-type.
