Since this is "C" there are not namespaces and libraries commonly choose
a particular name prefix for their symbols.
In case of libcurl, that is "curl_".
We should avoid using the same name prefix, and choose something distinct.

$ nmcli c add type ovs-port ifname ovsport0
Error: Failed to add 'ovs-port-ovsport0' connection: connection.type:
Only 'ovs-port' connections can be enslaved to 'ovs-bridge'
nm_streq0() is not good here. It fails (with a wrong error message) even
when the slave_type is not set, which it shouldn't since slave_type can
be normalized. The real problem is the lack of the master property.
This fixes the condition:
$ nmcli c add type ovs-port ifname ovsport0
Error: Failed to add 'ovs-port-ovsport0' connection: connection.master:
A connection with a 'ovs-port' setting must have a master.
Corrects the error message:
$ nmcli c add con-name br0 type bridge
$ nmcli c add type ovs-port ifname ovsport0 parent br0
Error: Failed to add 'bridge-slave-ovsport0' connection: connection.slave-type:
'ovs-port' connections must be enslaved to 'ovs-bridge', not 'bridge'
And gets rid of a confusing nm_streq0 use when comparing the type, since
at that point type must not be NULL anymore.

We previously kept any acd-manager running if the device was
disconnected. It was possible to trigger a crash by setting a long
dad-timeout and interrupting the activation request:
nmcli con add type ethernet ifname eth0 con-name eth0+ ip4 1.2.3.4/32
nmcli con mod eth0+ ipv4.dad-timeout 10000
nmcli -w 2 con up eth0+
nmcli con down eth0+
After this, the n-acd timer would fire after 10 seconds and try to
disconnect an already disconnected device, throwing the assertion:
NetworkManager:ERROR:src/devices/nm-device.c:9845:
activate_stage5_ip4_config_result: assertion failed: (req)

Such failures during connectivity checks, may happen frequently
and due to external causes. Don't log with error level to avoid
spamming the logfile.

Commit 10753c3616 ("manager: merge VPN handling into
_new_active_connection()") added a check to fail the activation of
VPNs when a device is passed to ActivateConnection(), since the device
argument is ignored for VPNs.
This broke activating VPNs from nm-applet as nm-applet sets both the
specific_object (parent-connection) and device arguments in the
activation request.
Note that we already check in _new_active_connection() that when a
device is supplied, it matches the device of the parent
connection. Therefore, the check can be dropped.

In device_ipx_changed() we only keep track of dad6_failed_addrs
addresses if the device's state is > DISCONNECTED.
For the same reason, we should also do that in queued_ip_config_change().
But it's worse. If the device is in state disconnected, and the user
externally adds IPv6 addresses, we will end up in queued_ip_config_change().
It is easily possible that "need_ipv6ll" ends up being TRUE, which results
in a call to check_and_add_ipv6ll_addr() and later possibly
ip_config_merge_and_apply (self, AF_INET6, TRUE);
This in turn will modify the IP configuration on the device, although
the device may be externally managed and NetworkManager shouldn't touch it.

(cherry picked from commit 890c748643)
We first iterate over addresses that might have failed IPv6 DAD and
update the state in NMNDisc.
However, while we do that, don't yet invoke the changed signal.
Otherwise, we will invoke it multiple times (in case multiple addresses
failed). Instead, keep track of whether something changed, and handle
it once a bit later.
(cherry picked from commit f312620276)
Whenever we process queued IP changes, we must handle all pending
dad6_failed_addrs. This is, to ensure we don't accumulate more
and more addresses in the list.
Rework the code, by stealing the entire list once at the beginning
dad6_failed_addrs = g_steal_pointer (&priv->dad6_failed_addrs);
and free it at the end:
g_slist_free_full (dad6_failed_addrs, (GDestroyNotify) nmp_object_unref);
This makes it easier to see, that we always process all addresses in
priv->dad6_failed_addrs.
(cherry picked from commit e2c13af805)
There is no change in behavior, however don't handle dad6_failed_addrs
and dad6_ip6_config in the same block.
While both parts are related to IPv6 DAD, they do something rather
different:
- the first block, checks all candidates from dad6_failed_addrs whether
they actually indicate DAD failed, and handles them by notifying
NMNDisc about failed addresses.
- the second block, checks whether we have now all addresses from
dad6_ip6_config that we are waiting for.
Split the blocks.

We don't need to cancel the current idle-action and schedule a new
one. Just return and wait to be called again.
Also, drop the logging. Similarly, we don't log the postponing for
the previous case either.
(cherry picked from commit 63cf5bd249)
We also cancel the idle handler
nm_clear_g_source (&priv->queued_ip_config_id_x[IS_IPv4])
which means, nobody is going to process these addresses (at least
for the moment).
The purpose of "dad6_failed_addrs" is to keep track of addresses that
might be interesting for checking about DAD failures. If we are no
longer reacting on IP changes (because the idle handler was removed),
we also no longer need these addresses.
(cherry picked from commit dbb936e5c8)
This simplifies commit 31ca7962f8.
We don't need the boolean flags like "queued_ip4_config_pending" to
track whether we received any platform signals while being not yet
initialized in platform (udev, NM_UNMANAGED_PLATFORM_INIT).
In general, as long as the device is NM_UNMANAGED_PLATFORM_INIT,
all platform signals are ignored. And when the device becomes managed,
we schedule anyway an initial config-change.

We use the email address of the user as their ID. In this case,
there is no need to restrict the match based on the name as well.
In practice, this makes no difference at all, because these email
addresses only come with the present names.
(cherry picked from commit d1aca62475)
This allows us to disambiguate committers. The list was compiled
manually, with preference of latter e-mail addresses if more were used
throughout the history.

"debug" was documentation in `man NetworkManager.conf` as a valid
logging backend. However, it was completely ignored by
nm_logging_syslog_openlog().
In fact, it makes not sense. Passing debug = TRUE to
nm_logging_syslog_openlog(), means that all messages will be
printed to stderr in addition to syslog/journal. However, when
NetworkManager is daemonizing, stderr is closed.
Whether NetworkManager is daemonizing depends entirely on command
line options --no-daemon and --debug. Hence, the logging backend "debug"
from the configuration file either conflicts or is redundant.
Also, adjust logging backend description in `man NetworkManager.conf`.
Also, log a warning about invalid/unsupported logging backend.

It just makes more sense to first fully setup logging, and then fetching
the timestamp. In practice, the effect previously was very similar.

Delay warning about invalid domains until we setup syslog and nm-logging.

They are known to be racy and occasionally break. Especially in
cases where the system's CPU is busy, like during parallel
`make check -j`.
It's likely a bug in libnm-glib. libnm-glib is deprecated, and the
library didn't significantly change now for several releases.
Let's not invest effort into finding bugs in the deprecated library,
bugs that are known to exist. Also, at this point, larger rework
of libnm-glib is not going to happen anymore.
Retry the test up to 5 times, trying to workaround the test failures.

'num_grat_arp' and 'num_unsol_na' are actually the same attribute on
kernel side, so if only 'num_grat_arp' is set in configuration, we
first write its value and then overwrite it with the 'num_unsol_na'
default value (1). Instead, just write one of the two option.

If commit_mtu() is called multiple times and dev->get_configured_mtu()
returns @is_user_config=FALSE, only the first call changes the
MTU. So, for example, when the parent MTU of a VLAN changes, we apply
the new MTU only the first time.
Rework the handling of MTU in NMDevice, and store the source of the
configured MTU. When commit_mtu() is called again, we ask the subclass
a MTU to configure and apply it only if the source has higher
priority, or when the parent MTU changed.
(cherry picked from commit 2f8917237f)
Instead of returning a boolean @is_user_config value from
get_configured_mtu(), return an mtu-source enum with possible values
NONE,CONNECTION. This enum will be expanded later; for now there is no
change in behavior.
