A connection that fails due to dependency-failed is not able to
reconnect until the master connection activates again; when this
happens, the master clears the blocked reason for all its slaves in
activate_slave_connections() and tries to reconnect them. For this to
work, the slave should be marked as blocked when it fails with
dependency-failed.

If the device state change (to disconnected or unmanaged) triggered by
a sleep event happens after the wake, the devices becomes wrongly
unmanaged and it's necessary to manually manage it again, or restart
NM.
During the wake event we should disconnect the device_sleep_cb()
callback for all devices because we don't want to react to state
changes anymore; in particular we don't need to detect when the device
becomes disconnected to unmanage it.

NetworkManager can't control the name of the PPP interface name
created by pppd; so it has to wait for the interface to appear and
then rename it. This happens in nm_device_take_over_link() called by
nm-device-ppp.c:ppp_ifindex_set() when pppd tells NM the ifindex of
the interface that was created.
However, sometimes the initial interface name is already correct, for
example when the connection.interface-name is ppp0 and this is the
first PPP interface created.
When this happens, nm_device_update_from_platform_link() is called on
the NMDevicePPP and it sets the device ifindex. Later, when pppd
notifies NM, nm_device_take_over_link() fails because the ifindex is
already set:
nm_device_take_over_link: assertion 'priv->ifindex <= 0' failed
Make nm_device_take_over_link() more robust to cope with this
situation.

The commit breaks many nmstate CI tests. It also breaks the
autoconnect-slaves functionality: if the master gets reactivated and
the slave was active, the slave is not reconnected.
A different solution is needed for the original issue.
This reverts commit 024e983c8e.

When there are two patch ports connected, each of them must reference
the other; however they can't be created in a single transaction
because they are part of different bridges (so, different
connections). Therefore, the first patch that gets activated will
always fail with "No usable peer $x exists in 'system' datapath" until
the second patch exists.
In theory we could also match the error message, however this doesn't
seem very robust as the message may slightly change in the future.

The 'peer' property of ovs-patch is inserted into the 'options' column
of the ovsdb 'Interface' table. The ovs-vswitchd.conf.db man page says
about it:
options : peer: optional string
The name of the Interface for the other side of the patch. The
named Interface’s own peer option must specify this Interface’s
name. That is, the two patch interfaces must have reversed name
and peer values.
Therefore, it is wrong to validate the peer property as an IP address
and document it as such.

Autoconnect-slaves currently forces an activation of all slaves, even
if there is already an active connection for them. This is bad because
at boot slaves first try to autoconnect, then the autoconnect-slaves
of the master kicks in and disconnects/reactivates them.
The only reason why the forceful reactivation was added was to fix
[1]; in that scenario, a slave connection is already active as
non-slave; then it is updated to be a slave; later, the master with
autoconnect-slaves is manually activated. NetworkManager should detect
that the slave connection must now be activated by autoconnect-slaves.
Add a specific check for such situation, instead of always
reactivating all slaves.

When the interface is in IPv4 or IPv6 shared mode and the user didn't
specify an explicit zone, use the nm-shared one.
Note that masquerade is still done through iptables direct calls
because at the moment it is not possible for a firewalld zone to do
masquerade based on the input interface.
The firewalld zone is needed on systems where firewalld is using the
nftables backend and the 'iptables' binary uses the iptables API
(instead of the nftables one). On such systems, even if the traffic is
allowed in iptables by our direct rules, it can still be dropped in
nftables by firewalld.

Install a NM-specific firewalld zone to be used for interfaces that

For ip-tunnel modes that encapsulate layer2 packets (gretap and
ip6gretap) we allow the presence of an ethernet setting in the
connection and honor the cloned-mac-address specified in it.
For all other modes, the ethernet setting is removed during
normalization, but a value different from 'preserve' could be set via
global default.
The kernel doesn't allow setting a MAC for layer3 devices, don't do
it.

Currently any error encountered in n_dhcp4_c_connection_dispatch_io()
causes a dispatch failure and interrupts the library state
machine. The recvmsg() on the socket can fail for different reasons;
one of these is for example that the UDP request previously sent got a
ICMP port-unreachable response. This can be reproduced in the
following way:
ip netns add ns1
ip link add veth0 type veth peer name veth1
ip link set veth1 netns ns1
ip link set veth0 up
cat > dhcpd.conf <<EOF
server-identifier 172.25.0.1;
max-lease-time 120;
default-lease-time 120;
subnet 172.25.0.0 netmask 255.255.255.0 {
range 172.25.0.100 172.25.0.200;
}
EOF
ip -n ns1 link set veth1 up
ip -n ns1 address add dev veth1 172.25.0.1/24
ip netns exec ns1 iptables -A INPUT -p udp --dport 67 -j REJECT
ip netns exec ns1 dhcpd -4 -cf dhcpd.conf -pf /tmp/dhcp-server.pid
If a client is started on veth0, it is able to obtain a lease despite
the firewall rule blocking DHCP, because dhcpd uses a packet
socket. Then it fails during the renewal because the recvmsg() fails:
dhcp4 (veth0): send REQUEST of 172.25.0.178 to 172.25.0.1
dhcp4 (veth0): error -111 dispatching events
dhcp4 (veth0): state changed bound -> fail
The client should consider such errors non fatal and keep running.

If a device only has an IPv6 link-local address, we don't generate an
assumed connection. Therefore, when a new slave connection (without IP
configuration) is activated on the device, we don't deactivate any
existing connection and the link-local address remains configured.
The IP configuration of an activated slave should be predictable and
not depend on the previous state; let's flush addresses and routes on
activation.

Since commit c1907a218a ('libnm-core: remove gateway when
never-default=yes in NMSettingIPConfig'), the gateway gets normalized
away when the profile has never-default set.
That means,
$ nmcli connection modify "$PROFILE" ipv4.never-default yes ipv4.gateway 192.168.77.1
does not set the gateway. Likewise, if your profile has already never-default
enabled,
$ nmcli connection modify "$PROFILE" ipv4.gateway 192.168.77.1
will have no effect. That is confusing and undesirable.
Note that we don't adjust the GObject property setter for "gateway" to clear
never-default. I feel, setting one property in libnm should preferably
not unset another (there are exceptions to the rule, like for team
properties). However, for nmcli it's clear in which order properties
are set, so this change is right for the client tool.
