Failed to configure eth1 IP address

[mine260309]

Unexpected behavior you saw With a fresh build, I am unable to configure the IP address of eth1 (NCSI)

Expected behavior It shall be able to configure the IP address of eth1

To Reproduce Steps to reproduce the behavior:

1. Build and flash a fresh build of Intel-BMC/openbmc on CRB
2. Boot into OS
3. Run inband ipmi command to configure the IP:

   ipmitool lan set 1 ipsrc static
   ipmitool lan set 1 ipaddr <ip>
   ipmitool lan set 1 netmask 255.255.255.0
   ipmitool lan set 1 defgw ipaddr <gw-ip>

4. Wait for a few seconds, check the IP address, it's empty.

   # ipmitool lan print 1
   Set in Progress         : Set Complete

                           : OEM      :
   IP Address Source       : Static Address
   IP Address              : 0.0.0.0
   Subnet Mask             : 255.255.255.255
   MAC Address             : <mac>
   Default Gateway IP      : 0.0.0.0
   Default Gateway MAC     : 00:00:00:00:00:00
   802.1q VLAN ID          : Disabled
   RMCP+ Cipher Suites     : 3,17
   Cipher Suite Priv Max   : Not Available
   Bad Password Threshold  : Not Available

5. Connect BMC debug UART, configure the IP with dbus:

   root@intel-obmc:~# busctl call xyz.openbmc_project.Network /xyz/openbmc_project/network/eth1 xyz.openbmc_project.Network.IP.Create IP ssys "xyz.openbmc_project.Network.IP.Protocol.IPv4" "<ip>" 24 "<gw-ip>"
   o "/xyz/openbmc_project/network/eth1/ipv4/88e39147"

   The DBus call itself succeds, but the IP is not correctly configured, and after a few seconds, the D-Bus object /xyz/openbmc_project/network/eth1/ipv4/88e39147 disappears.

"MAC Address : " There is no MAC in your platform.

1. currently, if there is no MAC in chip, it should be random. https://github.com/openbmc/linux/blob/dev-5.3/drivers/net/ethernet/faraday/ftgmac100.c#L211
2. you also could set static mac. https://github.com/Intel-BMC/openbmc/blob/0f1b8401f7058fc88fbcf06c7e98c5ebadc23212/meta-openbmc-mods/meta-common/recipes-network/network/static-mac-addr/mac-check

I double checked in my side. Don't find such issue. System is working well.

NOTE: 1. Please remove asd, your met build issue. https://github.com/Intel-BMC/openbmc/blob/intel/meta-openbmc-mods/meta-common/classes/obmc-phosphor-image-common.bbclass#L14

2. Please make sure using the correct config based your CRB platform, take wht for example. export TEMPLATECONF=meta-openbmc-mods/meta-wht/conf/ Please remove the whole build folder if you changed the config.
3. Please make the drive working well. root@intel-obmc:~# cat /sys/class/net/eth1/address 32:48:3a:53:99:52

OK, will try to clean the build dir and try a clean build.

From your log, both eth0 and eth1 are connected. Please be noted that this issue occurs when only eth1 (NCSI) is connected, while eth0 is disconnected.

[kuiyingw]

Still working well, even disconnect the eth0. BTW: Please make sure your system could get MAC address correctly.

[mine260309]

What I observe is that the issue occurs on both eth0 and eth1. Below is how I reproduce the issue:

1. Do a factory reset, so that BMC's settings are default
2. Connect to BMC's debug UART, check the default eth configs:

   # cat /etc/systemd/network/00-bmc-eth1.network
   [Match]
   Name=eth1
   [Link]
   MACAddress=<xxx>
   Unmanaged=yes
   [Network]
   LinkLocalAddressing=yes
   IPv6AcceptRA=false
   DHCP=false
   [DHCP]
   ClientIdentifier=mac
   UseDNS=true
   UseNTP=true
   UseHostname=true
   SendHostname=true

   Be noted Unmanaged=yes is the root cause.

3. Assign an IP address, e.g.

   # busctl call xyz.openbmc_project.Network /xyz/openbmc_project/network/eth1 xyz.openbmc_project.Network.IP.Create IP ssys "xyz.openbmc_project.Network.IP.Protocol.IPv4" 
   "192.168.1.101" 24 "192.168.1.1"

   The expected behavior is that the IP will be added to eth1. But no IP is added. Checking the config:

   # cat /etc/systemd/network/00-bmc-eth1.network
   [Match]
   Name=eth1
   [Link]
   MACAddress=<xxx>
   Unmanaged=yes
   [Network]
   LinkLocalAddressing=yes
   IPv6AcceptRA=false
   DHCP=false
   [Address]
   Address=192.168.1.101/24
   [DHCP]
   ClientIdentifier=mac
   UseDNS=true
   UseNTP=true
   UseHostname=true
   SendHostname=true

   We can see that the IP is correctly written into the config, but due to Unmanaged=yes, systemd-networkd will not use this config file.

Seems there is an issue on setting the static ip addr. You could use DHCP get the ip address. It should not block you.

This issue is gone in the update branch, revision d2bd6ff4b Close.
