Package: iproute2
Version: 3.11.0-1
Severity: normal
While trying to fix a bug in python-nemu, I discovered a small bug in iproute2.
The output of the command "addr show" is not consistent, depending on the -o
flag.
See this example:
$ sudo modprobe dummy
$ ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group
default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN
group default qlen 1000
[..]
3: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state
DOWN group default qlen 1000
[..]
10: wwan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP
group default qlen 1000
[..]
358: dummy0: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN group default
link/ether 42:39:cf:86:bb:39 brd ff:ff:ff:ff:ff:ff
$ ip -o addr show
1: lo inet 127.0.0.1/8 scope host lo\ valid_lft forever preferred_lft
forever
1: lo inet6 ::1/128 scope host \ valid_lft forever preferred_lft
forever
10: wwan0 inet XXX/29 brd XXX scope global wwan0\ valid_lft forever
preferred_lft forever
10: wwan0 inet6 XXX/64 scope link \ valid_lft forever preferred_lft
forever
As you can see, the unconfigured interfaces are not shown with the -o
switch, which breaks python-nemu, as it uses the parser-friendly one-line
format.
Even if this looks like a minor bug, it is breaking other package, so hence the
normal severity.
