#19463: since @45354 dnsmasq fails to start & syntax error reported
-------------------------+------------------------
Reporter: kevindb | Owner: developers
Type: defect | Status: new
Priority: high | Milestone:
Component: base system | Version: Trunk
Keywords: dnsmasq |
-------------------------+------------------------
Since svn://svn.openwrt.org/openwrt/trunk@45354 dnsmasq has issues
starting up. Relevant lines in dnsmasq.init are
{{{
if [ ! -f /etc/dnsmasq.time ]; then
touch -t 197001010000 /etc/dnsmasq.time
chmod 0777 /etc/dnsmasq.time
fi
}}}
Unfortunately '-t' option to touch isn't supported, certainly on
base/default TP-Link Archer C7 config.
Creating a timestamp file outside of dnsmasq's own mechanism will
confuse it too. Dnsmasq's algorithm is simple in that if the
system time is later than the modified time on the timestamp
file then the system time is considered valid and dnssec signature
checking is performed. If time isn't valid then signature
time checking is not performed which will allow ntp server name
resolution to proceed. Once time has skipped forward, dnsmasq
will notice and the do full dnssec validation as well as creating
a timestamp file.
If the timestamp file doesn't exist then dnsmasq considers time
invalid until it exceeds 2015-01-01-00:00:00. Pre-creating a
timestamp file isn't helpful to this process.
The timestamp file must also survive reboot. I've attached a
patch which I think fixes these issues, though I'm unclear if
it works correctly with the new secure computing features of
procd.
