2021-03-16udhcpc: ignore zero-length DHCP options, take 2Denys Vlasenko
advance the optionptr by two bytes, not one Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-03-16udhcpc: ignore zero-length DHCP optionsRussell Senior
Discovered that the DHCP server on a TrendNet router (unknown model) provides a zero-length option 12 (Host Name) in the DHCP ACK message. This has the effect of causing udhcpc to drop the rest of the options, including option 51 (IP Address Lease Time), 3 (Router), and 6 (Domain Name Server), most importantly leaving the OpenWrt device with no default gateway. The TrendNet behavior violates RFC 2132, which in Section 3.14 declares that option 12 has a minimum length of 1 octet. It is perhaps not a cosmic coincidence that I found this behavior on Pi Day. This patch allows zero length options without bailing out, by simply skipping them. function old new delta udhcp_scan_options 183 172 -11 Signed-off-by: Russell Senior <russell@personaltelco.net> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-03-02ntpd: decrease INITIAL_SAMPLES from 4 to 3Denys Vlasenko
This reduces initial traffic to NTP servers when a lot of devices boot at once. Log inspection tells me we agressively burst-poll servers about 5 times at startup, even though we usually already update clock after second replies. INITIAL_SAMPLES can probably be even lower, e.g. 2, but let's be conservative when changing this stuff. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
