Title:
[SRU] IPv6 link local address is assigned even when
LinkLocalAddressing=no|ipv4
Status in systemd:
New

Fix Released
Status in systemd source package in Bionic:

Bug description:
[impact]
in some situations when a networkd interface is configured with
LinkLocalAddressing=no, networkd still assigns a link-local address to
it
[test case]
see comment 3.
note I was only able to reproduce this at boot time; if the vlan
interface is removed (i.e. 'sudo ip l del pppoe') and then networkd
restarted, the pppoe interface is created and does not have a link-
local address. This is due to this bug being triggered by timing, as
a vlan interface is raised by the kernel when its parent interface is
raised, in this case by networkd itself.
[regression potential]
this changes how ipv6ll addresses are managed and dropped, as well as
changing when foreign addresses are dropped (later in config process).
Any regressions would likely be around incorrectly setting ipv6ll
addresses, or complete failure to complete interface configuration.
[scope]
this is fixed upstream by:
https://github.com/systemd/systemd/pull/13927
and also requires the upstream PR referenced in the original description:
upstream patch: https://github.com/systemd/systemd/pull/13565
this is required for focal (uploaded already), eoan, and bionic. It
may be required for xenial.
[other info]
Note, the original description below is incorrect, the issue/patch it
references is not enough to fix this issue.
original description:
--
upstream issue: https://github.com/systemd/systemd/issues/12886
upstream patch: https://github.com/systemd/systemd/pull/13565
The upstream fix will be available in systemd 244.
Backport please. Thanks.
