Subject: net-tools: ifconfig doesn't show interface

Date: Wed, 27 Jan 2016 18:53:16 +0300

Package: net-tools
Version: 1.60-26+b1
Severity: important


ifconfig doesn't show interface (lxcbr0 on my config).

Steps to reproduce:

brctl addbr lxcbr
ip link set dev lxcbr up
brctl addbr lxcbr0
ip link set dev lxcbr0 up

# ifconfig | grep lxcbr
lxcbr     Link encap:Ethernet  HWaddr 00:1e:c9:d1:06:93

note - lxcbr0 not shown. ip link show all interfaces

# ip link | grep lxcbr
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master
lxcbr state UP mode DEFAULT group default qlen 1000
4: lxcbr: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue
state UP mode DEFAULT group default qlen 1000
62: lxcbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue
state UNKNOWN mode DEFAULT group default qlen 1000

backporting net-tools from sid helps.

Does it show it if you run 'ifconfig -a'? And if you configure ip addresses?

In any case, this bug does not seem to be severity:important, nor
deserving an upload to stable, which usually only happens for security
issues.

No.

total mess. But "./ifconfig testbr 10.4.0.1 netmask 255.255.255.0"
configure right interface, this is good.

If some user scripts parse output of this broken ifconfig - it may
configure firewall with wrong IP address or any other service.
