Subject: [PATCH 2/2] dns: sort the ip-data list when a new element is added
In nm_dns_manager_set_ip_config() we try to avoid calling update_dns()
unless something changes, because updating DNS is expensive and can
trigger other actions such as a new hostname resolution.
When we add a new ip_data, even if the new element is equivalent to
the old one that was removed, we need to sort the list again.
Fixes: ce0a36d20fa6 ('dns: better track l3cd changes')

Subject: [PATCH] dhcp: decline IPv6 lease if all adresses fail DAD
Currently we accept the DHCPv6 just after addresses are configured on
kernel, without waiting DAD result. Instead, wait that DAD completes
and decline the lease if all addresses are detected as duplicate.
Note that when an address has non-infinite lifetime and fails DAD,
kernel removes it automatically. With iproute2 we see something like:
602: testX6 inet6 2620::1234:5678/128 scope global tentative dynamic noprefixroute
valid_lft 7500sec preferred_lft 7200sec
Deleted 602: testX6 inet6 2620::1234:5678/128 scope global dadfailed tentative dynamic noprefixroute
valid_lft 7500sec preferred_lft 7200sec
Since the address gets removed from the platform cache, at the moment
we don't have a way to check the flags of the removal
message. Therefore, we assume that any address that goes away in
tentative state was detected as duplicate.

Subject: [PATCH] ovs: wait that links disappear during initial cleanup
At startup, we remove from ovsdb any existing interface created by NM
and later an interface with the same name might be readded. This can
cause race conditions. Consider this series of events:
1. at startup NM removes the entry from ovsdb;
2. ovsdb reports success;
3. NM inserts an interface with the same name again;
4. ovs-vswitch monitors ovsdb changes, and gets events for removal and
insertion. Depending on how those events are split in different
batches, it might decide:
4a. to delete the link and add it back, or
4b. to keep the existing link because the delete and insertion
cancel out each other.
When NM sees the link staying in platform, it doesn't know if it's
because of 4b or because 4a will happen eventually.
To avoid this ambiguity, after ovsdb reports the successful deletion
NM should also wait that the link disappears from platform.
Unfortunately, this means that ovsdb gets a dependency to the platform
code.

From 43c39b1e1ef66f2ecf970086fdd05ce9b0c7fedf Mon Sep 17 00:00:00 2001
From: Beniamino Galvani <bgalvani@redhat.com>
Date: Wed, 7 Sep 2022 16:50:02 +0200
Subject: [PATCH] core: wait for carrier before resolving hostname via DNS
If there is no carrier on a device, don't try to resolve the hostname
on it. Instead, subscribe to carrier change notifications and retry
again once carrier goes up.
