 |
|
Hello World.
I have recently installed system with kernel sources 4.4.26-gentoo.
Here is my /etc/udev/rules.d/70-my-network.rules file:
| Code: | SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="60:a4:4c:60:11:00", NAME="net0"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="00:1b:21:52:d8:48", NAME="net1"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="00:1b:21:52:d8:49", NAME="net2"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="00:1b:21:52:d8:4c", NAME="net3"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="00:1b:21:52:d8:4d", NAME="net4"
|
(I don't want to see enpXXXX network interfaces names and can't use ethX names so we decide to use netX names)
Here is my /etc/conf.d/net file:
| Code: | modules="iproute2"
config_net0="null"
vlans_net0="101 103"
config_net1="null"
config_net2="null"
config_net3="null"
config_net4="null"
vlan101_name="vlan101"
config_vlan101="192.168.101.37/24"
routes_vlan101="192.168.0.0/16 via 192.168.101.1"
vlan103_name="vlan103"
config_vlan103="192.168.103.37/24"
|
(net1 to net4 will be bonded later, so they are all null)
I'm using the same configs from long time ago at different servers and all worked fine. Until now.
Now I have those lines in my log at system start:
| Code: | Dec 22 12:30:42 bird2 [ 7.639663] udevd[1815]: starting version 3.1.5
Dec 22 12:30:44 bird2 [ 16.340208] udevd[1852]: Error changing net interface name vlan101 to net0: File exists
Dec 22 12:30:44 bird2 [ 16.340217] udevd[1852]: could not rename interface '7' from 'vlan101' to 'net0': File exists
Dec 22 12:30:44 bird2 [ 16.456223] udevd[1852]: Error changing net interface name vlan103 to net0: File exists
Dec 22 12:30:44 bird2 [ 16.456232] udevd[1852]: could not rename interface '8' from 'vlan103' to 'net0': File exists

How I can exclude those renaming attempts?
I have single rule file in /etc/udev/rules.d/, which I posted above.
Where is may be my mistake (if it is my)?
Or is it mistake from developers?

I found the answer.
Vlans are "linked" to net0, so thay have same MAC address as net0. So there are attempts to rename them to net0. Two years ago vlans was not affected by this rules - today are affected. I think that udev developers has reasons to change behavior of their program.
To exclude this weird renames - rules must contain one more element - SUBSYSTEMS=="pci". Physical device has parent (pci), vlan has no parent, so rules will affect only physical ethernet devices, not vlans.
P.S. Please exuse me my very poor english... |
