Package: ifupdown
Version: 0.8.19
Severity: normal
Hi,
Using allow-hotplug for InfiniBand devices does not work. The devices are never
brought up.
Example /etc/network/interfaces:
```
allow-hotplug ib0.dddd
iface ib0.dddd inet6 static
address fd44:1:5255::
netmask 64
pre-up echo connected > /sys/class/net/$IFACE/mode
dad-attempts 600
```
I am removing and loading the ib_ipoib kernel module. Loading the modules
produces following udev events:
```
$ udevadm monitor
[...]
KERNEL[78666.922735] add
/devices/pci0000:00/0000:00:02.0/0000:03:00.0/net/ib0 (net)
UDEV [78666.941473] add
/devices/pci0000:00/0000:00:02.0/0000:03:00.0/net/ib0 (net)
[...]
KERNEL[78666.959961] add
/devices/pci0000:00/0000:00:02.0/0000:03:00.0/net/ib1 (net)
UDEV [78666.979126] add
/devices/pci0000:00/0000:00:02.0/0000:03:00.0/net/ib1 (net)
```
These events should trigger ifupdown-hotplug:
```
$ udevadm test /devices/pci0000:00/0000:00:02.0/0000:03:00.0/net/ib0 2>&1 |
grep ifupdown
Reading rules file: /lib/udev/rules.d/80-ifupdown.rules
RUN 'ifupdown-hotplug' /lib/udev/rules.d/80-ifupdown.rules:5
run: 'ifupdown-hotplug'
```
I see no new output in the networking.service and cannot find 'ifupdown' logs
in /var/log.
