Introduce a new argument to specify a comma-separated list of NSS
services to use for the "resolve-address" command. For now only accept
"dns" and "files"; the latter can be used to do a lookup into
/etc/hosts.
Note that previously the command failed in presence of extra
arguments. Therefore, when downgrading NetworkManager without
restarting the service, the previously-installed version of the daemon
(newer) would spawn the helper with the extra argument, and the
newly-installed version of the helper (older) would fail. This issue
only impacts hostname resolution and can be fixed by just restarting
the daemon.
In the upgrade path everything works as before, with the only
difference that the helper will use by default both "dns" and "files"
services.
Don't strictly check for the absence of extra arguments, so that in
the future we can introduce more arguments without necessarily break
the downgrade path.
When ModemManager become available, NetworkManager resets
GDBusObjectManagerClient object.
But there is a race condition if object-added is emitted before
modm_ensure_manager(), we need to check existing objects if we want to be
in sync with ModemManager.

Also check for gateway equality when deduplicate routing entries. This
allows to support multiple routes to the same network using different
gateways. This is useful for Thread networks where multiple BRs route
to the same Thread network. If one of these BRs go offline, fallback to
a different router will be much quicker if multiple entries are present.
Note that quick fallback to a different router requires IPv6
reachability probe to be active. Typically Linux disables reachability
probes on Linux machines which act as IPv6 gateway (when forwarding is
enabled).
It might happen that write() returns -1, but the errno is not EINTR.
In that case, the length would be incremented by 1, and the data pointer
to the data being written would be moved back by 1 byte on every error.
Make it so that the function exits with an error if it indicates an error.

Useful to have easily accessible the info of all the distros that we
test, including the version of NM that they ship and their EOL dates so
we can know when to stop testing them.
For now this is only informative, but we can use this info, for example,
to generate the `.gitlab-ci/config.yml` file automatically for each
stable branch.
When the lease expires, the DHCP client emits a LEASE_UPDATE event
with a NULL l3cd. After returning from the handler, it sends
immediately a DHCP DISCOVER message to try to get a new lease.
It is important that when the DISCOVER gets sent the address is no
longer configured on the interface. Otherwise, the server could see
that it is already in use and assign a different one. Therefore,
remove the address synchronously when handling the event.

Currently, when the agent manager is sent a registration request
containing UTF-8 characters, it will form an invalid error message
using only one of the bytes from the UTF-8 sequence, which causes
an assertion in glib to fail, which replaces the returned error message
with "[Invalid UTF-8]". It will also print an assertion failure to the
console, or crash NetworkManager on non-release builds.
This commit makes it so that it instead prints out the character in
hexadecimal form if it isn't normally printable, so that it is once
again a valid UTF-8 string.

A signal handler is not the only place where we need to clean up after
an in-progress readline() on exit; we may do so when erroring out as
well:
Before (not also the missing line break, which is part of the cleanup):
$ (sleep 10; nmcli c del 'Red Hat Wi-Fi')
$ nmcli --ask d wifi connect 'Red Hat Wi-Fi'
Passwords or encryption keys are required to access the wireless network 'Red Hat Wi-Fi'.
Password (802-11-wireless-security.psk): Error: Connection activation failed: The device's active connection disappeared.
$ [terminal messed up, no echo]
After:
$ (sleep 10; nmcli c del 'Red Hat Wi-Fi')
$ nmcli --ask d wifi connect 'Red Hat Wi-Fi'
Passwords or encryption keys are required to access the wireless network 'Red Hat Wi-Fi'.
Password (802-11-wireless-security.psk):
Error: Connection activation failed: The device's active connection disappeared.
$ hello [terminal echo fine, wheee]

We currently submit builds to Coverity manually every now and then,
but it would make sense to submit them more frequently and periodically,
so that it can detect defects sooner.
Add a "coverity" stage to the pipeline, which submits a build to Coverit
(the scheduls currently set to run every week).

In the future we might want to specify filters when requesting netlink
dumps; this requires that strict check is enabled on the socket.
When enabling strict check, we need to pass a full struct in the
netlink message, otherwise kernel ignores it.
This commit doesn't change behavior.
Adds an option in the connectivity section to change the timeout before
the interface is deemed "limited". Previously, it was hardcoded to
20 seconds, but for our usecase (failing over to cell modem if
hardwired ethernet drops), it's nice to be able to failover to another
interface more quickly.
The OVS interface can be matched via MAC address; in that case, the
"connection.interface-name" property of the connection is empty.
When populating the ovsdb, we need to pass the actual interface name
from the device, not the one from the connection.

Currently, the Dockerfile expects /etc/systemd/journald.conf to exist on the base container,
but sometimes this may not be the case, for example on Fedora 40, which causes
the build process to fail if the host machine is also running Fedora 40.
Update the dockerfile to create a conf.d file instead, which has higher precedence.

The comment makes it sounds as if we could do without CAP_DAC_OVERRIDE
if we don't use OpenVSwitch, which is not true. At the very least it's
needed by the VPN plugins we spawn to access cert/key material from
users' homes.
For [connection*] and [device*] sections, any suffix is allowed in
the group.
However (at least for configuration snippets we ship upstream), we
want to give a suffix that matches the name of the configuration
snippet.
It seems more common to use [connection-*] instead of [connection.].
See also "examples/nm-conf.d/*.conf" and "15-carrier-timeout.conf" file
which contains a [device-15-carrier-timeout] section.
Note that this file (in Fedora) is not configuration (installed in
/usr/lib). It is thus not problematic to modify.

The group interface is only used during activation; there is no need
to add a pending action for it, because when the device is in
activating state it already delays "startup-complete" via other
pending actions.
The daemon is now capable of understanding and removing these prefix
tags by itself. It is better than this is not a responsibility of the
secret agent because it requires changes in all secret agents to work
properly (see https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/1536).
If the secret agent knows what these prefix tags are, it can remove them
only in the text that is displayed in the UI, but maintaining the
original string as the secret name that is returned to the daemon.
Secret agents that doesn't know what these prefix tags are won't do
anything with them, and they will also return the same string as secret
name, as expected. The only drawback is that they might display the full
string to the user, which is not a nice UX but it will at least work.
Also, allow to translate the secret name for the UI in libnmc.
Commit 345bd1b187 ('libnmc: fix secrets request on 2nd stage of 2FA
authentication') and commit 27c701ebfb ('libnmc: allow user input in
ECHO mode for 2FA challenges') introduced 2 new tags that hints for the
secret agents can have as prefix.
These tags were processed (and removed) in the secret agents, not in the
daemon. This is wrong because a system with an updated VPN plugin but a
not yet updated secret agent (like nm-plasma) will fail: it won't remove
the prefix and the daemon will save the secret with the prefix, i.e.
"x-dynamic-challenge:challenge-response" instead of just
"challenge-response". Then, VPN plugins doesn't recognize it, failing the
profile's activation. This is, in fact, an API break.
Also, if the VPN connection already existed before updating NM and the
VPN plugin, the secret flags are not added to the profile (they are only
added when the profile is created or modified). This causes the user's
first time response is saved to the profile, so the activation fails the
second and next times.
See:
- https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/1536
- https://gitlab.gnome.org/GNOME/NetworkManager-openvpn/-/issues/142
Anyway, in a good design the daemon should contain almost all the logic
and the clients should keep as simple as possible. Fix above's problems
by letting the daemon to receive the secret names with the prefix
already included. The daemon will strip it and will know what it means.
Note that this is done only in the functions that saves the secrets from
the data received via D-Bus. For example, nm_setting_vpn_add_secret
doesn't need to do it because this value shouldn't come from VPN
plugin's hints.
