It was documented to be an optional parameter. That is also in line
with g_dbus_connection_call(), which is essentially wrapped by nm_client_dbus_call().

In the past, nmp_lookup_init_object() could both lookup all object for a
certain ifindex, and lookup all objects of a type. That fallback path
already leads to an assertion failure fora while now, so nobody should
be using this function to lookup all objects of a certain type (for
what, we have nmp_lookup_init_obj_type()).
Now, remove the fallback path, and rename the function to what it really
does.
NMPObject is a union. It's not clear to me that C guarnatees that
designated initializers will meaningfully set all fields to zero. Use
memset() instead.
It can be useful to choose a different "ipv6.addr-gen-mode". And it can be
useful to override the default for a set of profiles.
For example, in cloud or in a data center, stable-privacy might not be
the best choice. Add a mechanism to override the default via global defaults
in NetworkManager.conf:
# /etc/NetworkManager/conf.d/90-ipv6-addr-gen-mode-override.conf
[connection-90-ipv6-addr-gen-mode-override]
match-device=type:ethernet
ipv6.addr-gen-mode=0
"ipv6.addr-gen-mode" is a special property, because its default depends on
the component that configures the profile.
- when read from disk (keyfile and ifcfg-rh), a missing addr-gen-mode
key means to default to "eui64".
- when configured via D-Bus, a missing addr-gen-mode property means to
default to "stable-privacy".
- libnm's ip6-config::addr-gen-mode property defaults to
"stable-privacy".
- when some tool creates a profile, they either can explicitly
set the mode, or they get the default of the underlying mechanisms
above.
- nm-initrd-generator explicitly sets "eui64" for profiles it creates.
- nmcli doesn' explicitly set it, but inherits the default form
libnm's ip6-config::addr-gen-mode.
- when NM creates a auto-default-connection for ethernet ("Wired connection 1"),
it inherits the default from libnm's ip6-config::addr-gen-mode.
Global connection defaults only take effect when the per-profile
value is set to a special default/unset value. To account for the
different cases above, we add two such special values: "default" and
"default-or-eui64". That's something we didn't do before, but it seams
useful and easy to understand.
Also, this neatly expresses the current behaviors we already have. E.g.
if you don't specify the "addr-gen-mode" in a keyfile, "default-or-eui64"
is a pretty clear thing.
Note that usually we cannot change default values, in particular not for
libnm's properties. That is because we don't serialize the default
values to D-Bus/keyfile, so if we change the default, we change
behavior. Here we change from "stable-privacy" to "default" and
from "eui64" to "default-or-eui64". That means, the user only experiences
a change in behavior, if they have a ".conf" file that overrides the default.

teamdctl_connect() has a parameter cli_type. If unspecified, the
library will try usock, dbus (if enabled) and zmq (if enabled).
Trying to use the unix socket if we expect to use D-Bus can be bad. For
example, it might cause SELinux denials.
As we anyway require libteam to use D-Bus, if D-Bus is available,
explicitly select the cli type.

Recent gettext version can extract and merge back strings from and to
various file formats, no need for intltool anymore.
https://wiki.gnome.org/Initiatives/GnomeGoals/GettextMigrationhttps://gitlab.freedesktop.org/NetworkManager/NetworkManager/issues/133https://github.com/NetworkManager/NetworkManager/pull/303https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/merge_requests/96
Clarification about the use of AM_GNU_GETTEXT_REQUIRE_VERSION:
In configure.ac, specify the minimum gettext version we require, rather
than the exact one. This fixes a situation where the autoconf macros
used for gettext will be the latest available on the system (for
example, 0.20); but the copied-in Makefile.in.in will be for the exact
version specified in configure.ac (in this case, 0.19).
In that situation, the gettext build rules will error out at `make` time
with the message:
*** error: gettext infrastructure mismatch: using a Makefile.in.in
from gettext version 0.19 but the autoconf macros are from gettext
version 0.20
Avoid that by specifying a minimum version dependency rather than an
exact one. This should not cause problems as we haven’t committed any
generated or external gettext files into git, so each developer will end
up regenerating the build system for their system’s version of gettext,
as expected.
See the subsection of
https://www.gnu.org/software/gettext/manual/html_node/Version-Control-Issues.html
for more information.
Note that autoreconf currently doesn’t recognise
AM_GNU_GETTEXT_REQUIRE_VERSION, so we must continue also using
AM_GNU_GETTEXT_VERSION. autopoint will ignore the latter if the former
is present. See
https://lists.gnu.org/archive/html/autoconf-patches/2015-10/msg00000.html.

This makes it more consistent with nettools' lease_to_ip4_config().
The benefit of having a self pointer, is that it provides the necessary
context for logging. Without it, these functions cannot correctly log.
At this point, it's clearer to get the necessary data directly from the
DHCP client instance, instead of having the caller passing them on
(redundantly).
For an IPv4 subnet mask we expect that all the leading bits are set (no
"holes"). But _nm_utils_ip4_netmask_to_prefix() does not enforce that,
and tries to make the best of it.
In face of a netmask with holes, normalize the mask.
We have two variants of the function: nm_utils_ip4_netmask_to_prefix()
and _nm_utils_ip4_netmask_to_prefix(). The former only exists because it
is public API in libnm. Internally, only use the latter.
nm_utils_ip4_netmask_to_prefix() and nm_utils_ip4_prefix_to_netmask()
are public API in libnm.
We thus already have an internal implementation _nm_utils_ip4_prefix_to_netmask(),
for non-libnm users. Internally, we should never use the libnm variant.
For consistency and so that we have the helper available in
libnm-glib-aux, add _nm_utils_ip4_netmask_to_prefix().
There was already an nm_assert() assertion. Upgrade this
to a g_return_val_if_fail(). This function is public API,
so this is potentially an API break. But it should highlight
a bug in the caller.
Apt is run for each package separately and errors are ignored. This is
not great -- it's slow and ignores errors. Therefore we sometimes end
up without packages we need.
Let's tolerate errors only for packages that we are know can fail to
install safely.
