description |
On a HiSilicon D06 system we noticed that interfaces provided by a plug-in "HINIC" network card are not getting assigned predictable names. We're getting "ethX" names instead of the expected "enPblah" names. |
[Impact]
Interfaces associated with Huawei "hinic" PCI adapters will not be assigned predictable names[*] and instead remain using the kernel names (e.g. eth0). This can lead to races where the interface names are not the same on every boot. For example, in a system with both 2-port hinic and 2-port igb devices, the hinic interfaces would be eth0 & eth1 if the kernel finished probing hinic before igb loaded. But if igb completes loading first, the hinic interfaces would be eth2 & eth3.
[*] https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/
[Test Case]
grep ^eth /proc/net/dev
[Fix]
There's an upstream fix that properly associates the hinic interfaces with their PCI devices, providing udev with the info it needs to generate a predictable name.
[Regression Risk]
The big regression risk here is with existing bionic installs w/ hinic devices. They will be currently using "eth" names by default, and this change will cause those names to change to "enP" names after upgrade. However, in only certain configs are those "eth" names reliable (e.g. only NIC in the system is a hinic plug-in card). It sucks to introduce such a change in a stable release - but users will be bitten by this when they upgrade or transition to the HWE kernel anyway if we don't. |
