The check whether the current setting are already as expected are wrong.
The reason is that nm_platform_ethtool_set_link_settings() also sets
the announced ethernet modes, but nm_platform_ethtool_get_link_settings()
does not give them.
That means, we cannot check whether the current link configuration is
the same, because the getter doesn't give that information.
Consequently, we must not skip the setting on the assumption that
there is nothing to change.
This bug has bad effects. If the device is currently activated with ethtool
option set, then re-activating the profile will result in wrongly
skipping the update.

Disabling autoneg is not supported for Gigabit ethernet. But it seems that
ixgbe also doesn't honor
ethtool -s enp5s0f0 speed 100 duplex full autoneg off
As a workaround, when we disable autoneg then always set the advertised
modes too. I think (hope) that should not have a bad effect otherwise,
but seems most sensible for ixgbe.

There is no point in logging the current speed/duplex. OK, with
the "*", we could at least see whether the printed values are
to be set, or are currently configured on the interface.
But mixing these two outputs is confusing and meaningless.
Either log what we are about to do, or what the current configuration
is. Not a mix of both.

libnm-platform.la depends on libnm-udev-aux and libnm-base.
Only by accident this was working, because we happened to use
no symbol in the test that required any of these dependencies.
A small change to the test can (and will soon) change that. Fix the
build to link the right library.

For IPv4, the order is not like for IPv6. Of course not.
Fixes: 7aa4ad0fa2 ('nmcli/docs: better describe ipv[46].addresses in `man nm-settings-nmcli`')
(cherry picked from commit 2f3c2647d2)
Commit c631aa48f0 ('platform: capture NMIP[46]Config from platform
with correct (reversed) order of IP addresses') changed this for IPv6
and IPv4, but it's not correct for IPv4.
For IPv6, later `ip addr add` calls adds a new primary address, which
is also listed in `ip addr show` first. Hence, as NMIP6Config tracks
addresses in increasing priority, while NMPlatform tracks them as
exposed by kernel, the order when appending addresses form platform
to NMIP6Config must be reversed.
That is not the case for IPv4. For IPv4, later `ip addr add` calls
add a secondary IP address. Also, in `ip addr show` output they are
appended. Consequently, IPv4 addresses are tracked by NMPlatform with
decreasing priority (in the reverse order than for IPv6).
Fix constructing the NMIP4Config by fixing the address order. This is
important, because during restart devices get assumed and our code would
configure the order of addresses as it finds them.
Fixes: c631aa48f0 ('platform: capture NMIP[46]Config from platform with correct (reversed) order of IP addresses')
(cherry picked from commit c380893dc6)
Fix the order of IP addresses when assuming devices (service restart).
The order of IP addresses matters to kernel for selection of source IP
address.
If all other properties are equal ([1]), for IPv6, the address added *last*
will be preferred. That is the address you see *first*` in `ip -6 addr show`.
NMPlatform also preserves that order, so the address *first* is the most
important one.
On the other hand, in a connection profile, `ipv6.addresses` lists
addresses in increasing priority (the last address is the primary one).
That is for compatibility with initscripts, which iterates over the
list of addresses and calls `ip addr add` (meaning, the last address
will be added last and is thus preferred by kernel).
As the priority order in the profile is reversed, also the priority
order in NMIP[46]Config is reversed. Fix creating an NMIP[46]Config
instance from platform addresses to honor the priority.
This has real consequences. When restarting NetworkManager, the interface
stays up with the addresses configured in the right order. After
restart, the device gets assumed, which means that the NMIP[46]Config
instance from the connection is not yet set, only the config from the
platform gets synchronized. Previously the order was wrong, so during
restart the order of IP addresses was reverted.

It seems slightly nicer not to leave a dangling pointer at the
end of the iteration. Then you could do something like
nm_dedup_multi_iter_init(&iter, head_entry);
while (nm_dedup_multi_iter_next(&iter)) {
if (some_condition())
break;
}
if (!iter.current)
printf("iterated to the end\n");
As nm_dedup_multi_iter_next() and nm_dedup_multi_iter_init() are inline
functions, the compiler should even be able to see that the initial
setting becomes unnecessary (the field will be initialized by the
first nm_dedup_multi_iter_next()). Likewise, the final clearing
of the field might also be optimized away at the end of the iteration
(if, as in the common case, the iterator is not accessed afterwards).
(cherry picked from commit 53070705b0)
NetworkManager handles "add" and "move" actions the same way, by
tracking the "struct udev_device" instance.
Still, this means that also for move events, we need the right
attributes set.

(cherry picked from commit b57c1af814)
Now that NetworkManager on Fedora 33 and RHEL 9 no longer writes
ifcfg-rh files by default ([1]), ifup/ifdown became less useful.
Possibly users shouldn't use it and it would be fine that new-style profiles
(keyfile) no longer work with these commands. But this is deemed as too
disruptive for users.
Note that our previous ifup/ifdown compat scripts only honored the argument
to be part of the ifcfg filename. That was not what initscripts were doing,
which called `need_config()` function that searched also the contents of
the files. With this extension, ifup/ifdown gets smarter too, to better
guess what the user might have wanted.
Extend the script by making it smarter, and to work with connection profile
names.
With this extension we further solidify ifup/ifdown as part of NetworkManager
command line API. That is problematic, because these tools pollute the
$PATH, by not having a clear NM-specific name. Also, these scripts
should only exist on Fedora/RHEL, which makes their usage non-portable
to other distros.
Also, other distros already ship different tools with name ifup/ifdown.
Extending the use of these scripts is thus undesirable, as it furthers
distro-specific commands.
Still, these arguments seem to not hold and users need to be "helped".
As Fedora users cannot be expected to unlearn "ifup" today, there is no
reason to assume they could in a few years. This likely means we will
never get rid of these scripts.
Also, if we truly would make ifup/ifdown part of NetworkManager, then a better
implementation would be that nmcli honors being called with these names.
That is not done, because nmcli's implementation currently is not as
nice to make that extension trivial (as it should be). It also would
mean to embrace ifup/ifdown officially. A shell script works well enough
as a hack.

During reload, firewalld drops the current runtime configuration.
NetworkManager should listen to that, and reconfigure the zones
that it cares about.
(cherry picked from commit 0f100abd85)
As we keep track of the current name owner, use its unique name
for the D-Bus requests.
We also track when the name owner changes, so at the point when we make
the D-Bus call, the current name owner was still running. We should talk
to it directly. If at the same time, firewalld restarts, we go through
our usual tracking of the name owner and will retry -- but always
talking to the unique name.
