From c2efc973d593e77db84091b4bc71cdb7b412b189 Mon Sep 17 00:00:00 2001 From: Henrique de Moraes Holschuh Date: Sun, 1 Mar 2020 00:08:43 -0300 Subject: [PATCH] dnsmasq: fix dnssec+ntp chicken-and-egg workaround (FS#2574) Fix the test for an enabled sysntp initscript in dnsmasq.init, and get rid of "test -o" while at it. Issue reproduced on openwrt-19.07 with the help of pool.ntp.br and an RTC-less ath79 router. dnssec-no-timecheck would be clearly missing from /var/etc/dnsmasq.conf.* while the router was still a few days in the past due to non-working DNSSEC + DNS-based NTP server config. The fix was tested with the router in the "DNSSEC broken state": it properly started dnsmasq in dnssec-no-timecheck mode, and eventually ntp was able to resolve the server name to an IP address, and set the system time. DNSSEC was then enabled by SIGINT through the ntp hotplug hook, as expected. A missing system.ntp.enabled UCI node is required for the bug to show up. The reasons for why it would be missing in the first place were not investigated.
