[Dnsmasq-discuss] DNS recursion only works in debug mode

[Matus UHLAR - fantomas]

Hello,

I have upgraded my router which included upgrading dnsmasq 2.80 to 2.86.

(Turris OS 5.4.4 based on openwrt 19 to 6.0.1 based on OpenWrt 21.02.05)

in the current version, dnsmasq returns REFUSED for external lookups:

% dig +nocmd +noquestion +nostats fantomas.fantomas.sk @gw.lan
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 13206
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1

;; OPT PSEUDOSECTION:
; EDNS: version: 0, flags:; udp: 1232
; EDE: 14 (Not Ready)

local lookups work correctly.

when I run dnsmasq with "-d" alias "--no-daemon" option, resolving works:

root at turris:/srv/tos6# /usr/sbin/dnsmasq -C /var/etc/dnsmasq.conf.cfg01411c -k -x /var/run/dnsmasq/dnsmasq.cfg01411c.pid -d
dnsmasq: started, version 2.86 cachesize 150
dnsmasq: DNS service limited to local subnets

dnsmasq: UBus support enabled: connected to system bus

If I run dnsmasq manually with exactly the same config file but without -d, 
same problem appears:

root at turris:/srv/tos6# /usr/sbin/dnsmasq -C /var/etc/dnsmasq.conf.cfg01411c -k -x /var/run/dnsmasq/dnsmasq.cfg01411c.pid

even after multiple attempts.


I have tried to play with config options without success, 
running with --log-debug option, no change (and no logs that would explain).
running with --keep-in-foreground caused no change either.

Any idea what could be the problem?
