Using dnsmasq 2.90 + the patch to fix the infinite loop, it seems like filtering is
applied when calling e.g., "SetFilterA false" over dbus. In the script below,
the first lookup succeeds but subsequent lookups after the initial application of the
filter fail to return anything.
It looks like I had a severe attack of "it compiles, ship it!" when the
RR filtering code got generalised to filter any RR type, and broke the
DBus methods entirely.

Should fix things, and I did test this time :)
Cheers,

The output is something like:

dnsmasq logs this:
[Feb 20 11:03:28] daemon dnsmasq[30672]: query[A] postmarketos.org from
127.0.0.1
[Feb 20 11:03:28] daemon dnsmasq[30672]: forwarded postmarketos.org to 1.1.1.1
[Feb 20 11:03:28] daemon dnsmasq[30672]: config postmarketos.org is NODATA-IPv4
I can try to bisect this, but thought I'd ask on here if this looks familiar
since bisecting dnsmasq isn't as easy :)
