Bug#795151: Kernel panic on shutdown after "ip -6 neigh add proxy ..."
Package: linux-image-3.16.0-4-amd64
Version: 3.16.7-ckt11-1+deb8u3
Tags: ipv6
On a virtual machine running jessie (in a pretty default configuration,
using systemd, etc.), I have an OpenVPN server configured like this:
https://community.openvpn.net/openvpn/wiki/IPv6
I use "ip -6 neigh add proxy ..." statements to configure the IPv6
routed block used for assigning addresses to the VPN clients, with
these rules in /etc/network/interfaces:
iface eth0 inet6 static
address xxxx:xxxx:xxxx:7::1
netmask 64
gateway fe80::1
up ip -6 neigh add proxy xxxx:xxxx:xxxx:8::1000 dev $IFACE
up ip -6 neigh add proxy xxxx:xxxx:xxxx:8::1001 dev $IFACE
up ip -6 neigh add proxy xxxx:xxxx:xxxx:8::1002 dev $IFACE
down ip -6 neigh del proxy xxxx:xxxx:xxxx:8::1000 dev $IFACE
down ip -6 neigh del proxy xxxx:xxxx:xxxx:8::1001 dev $IFACE
down ip -6 neigh del proxy xxxx:xxxx:xxxx:8::1002 dev $IFACE
(The "down ip ..." statements have no influence on the bug described
here, the kernel panic happens also if they are removed.)
This all works, until attempting a "shutdown -r" which causes the
systemd shutdown process to proceed as expected all the way until it's
supposed to execute "networking: Deconfiguring network interfaces..."
but instead gets a kernel panic, logging the following in journalctl:
