Package: linux-image-3.16.0-4-amd64

Version: 3.16.36-1+deb8u2

 

After the upgrade to the new kernel version we’ve noticed that the default src IP have changed from the primary interface eth0 to the IP set for the subinterface eth0:1. This has caused problem with some of our services such as bind that now uses the wrong IP for zone transfers which fails.

 

# ip route show

default via xxx.xxx.240.1 dev eth0

xxx.xxx.240.0/27 dev eth0  proto kernel  scope link  src xxx.xxx.240.11

 

/etc/network/interfaces:

# This file describes the network interfaces available on your system

# and how to activate them. For more information, see interfaces(5).

 

source /etc/network/interfaces.d/*

 

# The loopback network interface

auto lo

iface lo inet loopback

 

# The primary network interface

allow-hotplug eth0

iface eth0 inet static

        address xxx.xxx.240.9

        netmask 255.255.255.224

        gateway xxx.xxx.240.1

        pre-up iptables-restore < /etc/iptables.rules

        post-down iptables-save -c > /etc/iptables.rules

 

auto eth0:1

iface eth0:1 inet static

        address xxx.xxx.240.11

        netmask 255.255.255.224

 

The reason we suspect this is something in the kernel is because that’s the only package upgraded and the only change made to the system prior to the problem appearing.

 

We are running Debian GNU/Linux 8.6, kernel 3.16.36-1+deb8u2

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
