Bug#815819: sysconfig-hardware udev rule ignores INTERFACE_NAME property

[Raphael Philipe Mendes da Silva]

Package: sysconfig-hardware
Version: 0.0.11
Severity: normal
X-Debbugs-CC: ***@linux.vnet.ibm.com,***@linux.vnet.ibm.com

I wanted to change the network interface name without using a custom
udev rule like 70-persistent-net.rules.
To do that, In Debian 8, I created a network interface hardware config
file (/etc/sysconfig/hardware/config-ccw-0.0.xxxx) with the following
content:

CCWGROUP_CHANS=(0.0.xxxx 0.0.xxxy 0.0.xxxz)
QETH_PORTNAME=OSAPORT
QETH_PORTNO=0
QETH_OPTIONS=(layer2)
INTERFACE_NAME=ethfoo

The interface is created and is up. However the name of the
interface remains enccw0.0.xxxx

I did a little debug and verified that the udev rule in the file /lib/udev/rules.d/65-sysconfig-hardware-net.rules was wrong:
It had:
SUBSYSTEM=="net", IMPORT{program}="/etc/sysconfig/scripts/hardware/udev-net $DEVPATH"
SUBSYSTEM=="net", ENV{INTERFACE_NAME}=="?*", NAME="$env{INTERFACE_NAME}"
But the correct would be:
SUBSYSTEM=="net", IMPORT{program}="/etc/sysconfig/scripts/hardware/udev-net $env{DEVPATH}"
SUBSYSTEM=="net", ENV{INTERFACE_NAME}=="?*", NAME="$env{INTERFACE_NAME}"

I tested the correction locally, and it worked.

I'm sure this problem also affects 0.0.12, since I took a look at the code.

Have you tried to create systemd network link file to assign a different
name? This should be then the long-term way how to rename interface
names. But I agree to correct the behavior in sysconfig-hardware for
correctness.

Thanks and kind regards,

Yes, I'm aware of this method. I just wanted to report this bug in case
someone else touch it.
