FS#1542 - DHCP (dnsmasq) server doesn't properly reply on requests on EdgeRouter Lite (LAN) #6657

diizzyy: r6745 (local build), broken |

diizzyy: I've finally looked into this further, it's a race condition during boot. Adding a 10 sec delay in dnsmasq's init.d script solves the issue, also restarting dnsmasq after bootup works. Comparing the logs to my WRT3200ACM it looks like it takes about 5 seconds more for port/network init to settle on the EdgeRouter Lite. |
koniu: Same on update of ar150 from 17.01 to 18.06rc1. udp:67 not bound. Manual dnsmasq restart after boot fixes the problem. On boot I'm seeing this: |
jow-: Can you please provide a complete "logread" of the broken state along with network and dhcp configuration? I can reproduce the S19dnsmasq error messages (which are somewhat expected and adressed with https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=1bad852ff597fd0535e02703f0c4b83447aaff45) but eventually some hotplug events should trigger a restart of dnsmasq with DHCP range set. |
dedeckeh: As I made a forced update the patch can now be found at https://git.openwrt.org/?p=openwrt/staging/dedeckeh.git;a=commit;h=f4c9a135e5df2b44634057b4e504ef84fe0b87ff |

I'll give it a try tomorrow |

There's some breakage on the EdgeRouter Lite regarding DHCP/dnsmasq on LAN.
Neither r6861 (local build) or r6868 (official snapshot) works.
Setting static ip on clients works so it's not a link issue.
