Thanks, the issue is fixed in newer series and I've sponsored your
bionic SRU now and updated the description to be a bit more specific
about the impact and what to verify
** Changed in: network-manager (Ubuntu)
Importance: Undecided => Low
** Changed in: network-manager (Ubuntu)
Status: Confirmed => Fix Released
** Description changed:
[Impact]
- * This affects Ubuntu 18.04 where Network Manager version 1.10.6 is
+ * This affects Ubuntu 18.04 where Network Manager version 1.10.6 is
used.
* Network manager might kill dhclient(6) and fail to start it again
causing the IPv6 address to be lost on a network that uses mixed
IPv4/IPV6.
The network status will still be seen as online in gnome since ipv4
is still active.
The user then have to manually remove the dhcpv6 lease files and
restart ipv6 connection/restart network manager to regain IPv6
connectivity.
* This is a cherry-pick from Network manager 1.10.8 (Ubuntu's version
is based on 1.10.6):
https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/commit/7fbbe7ebee99785e38d39c37e515a64a28edef0f
* Upstream bug:
https://bugzilla.gnome.org/show_bug.cgi?id=783391
[Test Plan]
* The exact conditions for reproducing this bug on mixed IPv4/IPv6
networks are not known but includes using both IPv4 and IPv6,
both using dhcp.
[Where problems could occur]
- * This patch could possibly break networking using and that would be bad.
- Network manager should be able to restart connection more properly with
- this patch though.
+ * The change is in the dchp lease expiration handling so verify that
+ there is no regression in dhcp renewals on different type of
+ configuration include IPv6
[Other Info]
* We have tested this patch on a couple of clients where we have seen this
this problem. If this patch is feasible to include in Ubuntu 18.04 we
could request more users to test.
