There’s an ntp hotplug script that creates a ‘time is valid’ flag file (/var/state/dnsmasqsec - being in /var means actually in tmp hence ram). If the file doesn’t exist already on stratum change then a) it gets created and b) SIGINTs dnsmasq. dnsmasq startup changes too… if the file doesn’t exist then it gets started with ‘—no-dnssec-timestamp’ expecting to be SIGINT’d by the hotplug script. If dnsmasq gets (re)-started and ntpd hotplug has created our ‘time valid’ file, then dnsmasq is started *without* —no-dnssec-timestamp’. There’s a whole raft of logic related to whether or not we’re using dnssec and quite what ntp client is being used. The SIGINT support was committed to LEDE/openwrt master (rather than CC, 1701 or whatever) around 60 minutes ago.

Out of interest, how does the LEDE plumbing deal with a restart of dnsmasq _after_ ntp has established lock? I've dogfooded the latest code into the boat's router which is running Chaos Calmer, and added a hotplug script which works great at startup when ntp comes alive after dnsmasq, but if I restart dnsmasq, there's nothing to tell dnsmasq that the time is already valid.

[Dnsmasq-discuss] IPv6 Router Advertisements not working
I setup a new vm running version 2.78 of dnsmasq. I have this in my config: enable-ra dhcp-range=fd01::,ra-stateless,ra-names,64,24h According to running dnsmasq in the foreground with -d dnsmasq-dhcp: DHCPv6 stateless on fd01:: dnsmasq-dhcp: DHCPv4-derived IPv6 names on fd01:: dnsmasq-dhcp: router advertisement on fd01:: dnsmasq-dhcp: IPv6 router advertisement enabled However I never see logs about sending router advertisements or receiving router solicitations. I also confirmed they aren’t going out with Wireshark. Are there any reasons why this wouldn’t work or does anyone know what else I should look into to figure it out. -- Matthew Keeler ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss

Beyond “gaaahh why didn’t I think of SIGINT”….. excellent. Understand the reasoning, agree, running chez Kevin and backport for LEDE master submitted. Thank you muchly.
