> Hello, I found the commit 627056febbf1b08e3028700184ee2f6c7ae799c6 breaks the legacy support of ipset. 

Thanks for catching this! Appreciate it.

> In commit 627056febb there is no "searching ipset now" in running logs. The return value of extract_request() is 0. It is possible that forwarded DNS queries are not allowed to be added to ipset.

This was an unintended regression because of some incorrect assumptions
regarding the callers of `extract_request`. I'll submit a patch to fix.
