LAN doesn't work in 19.07.2 custom build

For Developers
1

Hi!

I have been using DIR-615-C1 for many years with OpenWRT. I always used stable releases for this router, but after 17.01.4 I have to make custom builds.
Latest working firmware was custom build 18.06.4.
After that I compiled custom build 19.07.2 without pppoe, IPv6 and firewall(it's not need because I use this router as repeater).
Also I disabled all devices except DIR-615-C1 from kernel - [Solved] Building a smaller kernel for a specific device

Now LAN and WAN ports don't work: I can't ping any local address from the router and the router doesn't response to ping from LAN side. Physical layer works: LED blinks and I see in the log that link is up.
By the way WLAN works without problem.
LAN(eth0.1), WAN(eth1) and WLAN are in one bridge.

It is not a problem with memory: free RAM is above 8Mb, free ROM is above 300kb.

There are my configs below. Also there is the log from serial console.

Network config:

root@OpenWrt:~# cat /etc/config/network

        option proto 'static'

        option vlan '1'
        option ports '1 2 3 4 0t'

Wireless config:

root@OpenWrt:~# cat /etc/config/wireless

config wifi-device 'radio0'
        option type 'mac80211'
        option channel '11'

Is there any idea about this problem?
I have tried to compile standard 19.07.2 without any changes in menuconfig, but in this case eth0 and eth1 also do not work.
18.06.8 works without problem.

Is this how you have your network configured? Are these the actual addresses of the openwrt router? How about on your main network? Theses are not valid rfc1918 private address ranges and may be a large part of your problem. You could try 10.0.1.0/24 as an address space - that would be valid. You also need to ensure that the whole network is using the same subnet.

4

11.0.1.0/24 is my network and 11.0.1.1 is my main router. It is not a problem.

Eth in DIR615-C1 does not work also if it connects directly to laptop LAN port and network is 192.168.1.0/24.

5

Actually, it is a problem. Unless you are the US Department of Defense (specifically the DoD Network Information Center)

Source: whois.arin.net
IP Address: 11.0.1.0

There is a reason that the RFC1918 address ranges exist. Please use them.

Ok. I will use 10.0.1.0/24.
I wrote that it does not work with any network range(192.168.1.0/24 for example).
But it works with identical configuration with v18.06.
Problem is in firmware version because only with v19.07 it does not work.

7

After you have adjusted your main network and your AP, try again.

19.07 works well in the normal builds. I suspect that if there is a problem, it may be related to something not present and/or misconfigured in your custom image. You are, after all, building an image to fit into a 4MB flash device (if you haven't already, see this warning which applies mostly to a normal image, but still applies to custom images like what you are doing.

Also, are you using the image builder, or actually compiling from source? The image builder is much easier and faster, and you can simply omit packages that are not required to save space - there is a guide to help (de-)select the packages that will save you the most space.

8

I repeat one more time that I connect the device directly with laptop LAN port without main network and the network range of laptop LAN port is 192.168.1.0/24.

I know that. I have another devices with normal builds.

I am compiling from source because for my device DIR615-C1 is not possible to user image builder after LEDE v17. There is not DIR615-C1 in the device list of image builder in v18 and in v19.

9

Can you draw a diagram of your network topology, including devices addresses. That might make it more clear what is happening.

10

dir615

11

Really?

If you want help, provide relevant information. In this case, it would be the whole network as you want it to be working.

12

It is testing configuration without any network.
It has to work.

13

so what exactly are you doing to test it? If I look at the OP, you said

So does this imply that in the directly connected state, you cannot ping any local addresses? How are you testing that -- via serial into the device and then pinging an address from there?

14

In directly state I can't ping the laptop from the device and I can't ping the device from the laptop.
If I enable WLAN I can ping.

15

You can't ping the laptop from the device -- how are you accessing the device itself in order to try pinging things? (wifi, serial, something else?)

16

I can access via serial.

17

what do you see if you issue ifconfig?

Can the OpenWrt device ping itself (192.168.1.1) -- I think it should be able to do that, but if it doesn't, it implies that isn't connecting the address to the system for some reason.

Also, since these are 100Mbps ports, have you tried a crossover cable, just to make sure that isn't relevant here? It shouldn't be necessary in the first place, but if there is software logic to an auto-crossover feature in the chipset and it isn't working properly, maybe a crossover would help.
