[pkg-dhcp-devel] Bug#882250: isc-dhcp-server: The dhcpv6 server does not respond to solicits, and therefore does not hand out ipv6 leases.

[Robert Senger]

Package: isc-dhcp-server
Version: 4.3.5-3
Followup-For: Bug #882250

This issue seems to be caused by the Debian-specific patch dhcommon-
getifaddrs.patch, reverting this patch in the Debian Stretch source package and
compiling and installing the package also resolves the problem.

In my previous posts I forgot to mention that eth0 on my machine also has some
aliases:

eth0:0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 172.16.3.251  netmask 255.255.0.0  broadcast 172.16.255.255
        ether 00:0d:b9:0d:84:b0  txqueuelen 1000  (Ethernet)

eth0:1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 172.16.4.251  netmask 255.255.0.0  broadcast 172.16.255.255
        ether 00:0d:b9:0d:84:b0  txqueuelen 1000  (Ethernet)

eth0:2: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 172.16.2.251  netmask 255.255.0.0  broadcast 172.16.255.255
        ether 00:0d:b9:0d:84:b0  txqueuelen 1000  (Ethernet)

I do not know what makes the new method using getifaddr() fail on eth0 in my
specific case. Maybe the multiple ip6 addresses, maybe the aliases, maybe
anything other.
