Do you have the avahi-autoipd package installed?  This may not be coming
from netplan.

I think we should not block the SRU of the netplan that allows users to
declare their intended network config.  There will be some work to get
the backends to catch up, and that's ok.

[Bug 1771704] Re: support for ipv4 link-local addressing

2018-10-10 Thread Daniel Axtens
Hi,

I added this to my netplan-config-tester and it's turned up a couple of
issues with NetworkManager.

1) If a static IPv4 address is specified and link-local: [ipv4] is
specified, there is no link-local address added. The documentation
doesn't make this clear; it only refers to DHCP conflicting with link-
local.

network:
  ethernets:
ens7:
  addresses: [16.16.250.1/22]
  link-local: [ipv4]
  renderer: NetworkManager
  version: 2

ubuntu@netplan2:~$ sudo ip a flush dev ens7
ubuntu@netplan2:~$ sudo ip l set dev ens7 down
ubuntu@netplan2:~$ sudo netplan apply
ubuntu@netplan2:~$ sleep 15 # give LL addresses time to be set up
ubuntu@netplan2:~$ ip a show dev ens7
9: ens7:  mtu 1500 qdisc fq_codel state UP 
group default qlen 1000
link/ether 52:54:00:b4:02:6e brd ff:ff:ff:ff:ff:ff
inet 16.16.250.1/22 brd 16.16.251.255 scope global noprefixroute ens7
   valid_lft forever preferred_lft forever
inet6 fe80::5054:ff:feb4:26e/64 scope link 
   valid_lft forever preferred_lft forever

This is doubly wrong: there's not IPv4 LL address and there is an IPv6
LL address. Which leads me to bug 2...


2) With NM, link-local: [ipv4] and link-local: [] don't disable a IPv6 LL 
address.

If you modify the config file above to have link-local: [] and repeat
the test, you still get an IPv6 link-local address.


I don't know if you want to gate the backport on this working/being documented 
correctly or if you'd prefer this to go through for now while we get it fixed 
upstream. Let me know.

Regards,
Daniel

[Bug 1771704] Re: support for ipv4 link-local addressing

2018-09-27 Thread Mathieu Trudel-Lapierre
** Description changed:

+ [Impact]
+ Ubuntu users who make use of IPv4 link-local addresses.
+ 
+ [Test case]
+ 1) Add 'link-local: [ ipv4 ]' to the netplan configuration.
+ 2) Run 'sudo netplan apply'
+ 
+ [Regression Potential]
+ Enabling link local means additional addresses are available on the system, 
usually in the form "169.254.XXX.XXX". This is, in effect, a potential security 
issue if it is enabled on untrusted networks (it gives systems a fairly well 
known, discoverable IP address as attack surface). This is not considered a 
regression from previous releases of Ubuntu given that avahi has been available 
on desktop, with the same potential issue. The availability of extra addresses 
might however mean that the system is considered online or reachable via the 
additonal addresses earlier than previously possible, which may lead to 
confusion for the user.

+ 
  Per https://bugs.launchpad.net/ubuntu/+source/avahi/+bug/1717983, link-
  local address support was previously handled via integration between
  avahi-autoipd and dhclient.  systemd-networkd does not invoke dhclient.
  It also has direct support for configuring link-local ipv4 addresses.
  But this support is not enabled by default.
  
  It should be possible for a system configured via netplan to make use of
  link-local ipv4 addresses, without needing to configure systemd-networkd
  directly.
  
  Historically we do not turn on link-local ipv4 support automatically on
  servers (avahi-autoipd not installed by default), and we use link-local
  addresses only as a fallback when dhcp gives no response.  So this
  should likely not be enabled by default, but instead be exposed as an
  additional configuration option in netplan yaml.
