Functions derived from generators as `configure_file`,
`custom_target` and `i18n.merge_file` can use placeholders like
`@BASENAME@` that removes the extension from the input filename
string.
The output string has been replaced by this placeholder that
allows in some cases the use of less variables.
Seems that a quite common openswitch basic configuration consist of a
one bridge, one port and one interface, all with the same interface
name. When performing such configuration in NetworkManager you need to
specify the slave-type for the ovs-interface, otherwise the master
interface specified there may match the bridge interface, resulting in
an error.
So, let's specify the slave-type for the ovs-interface, so that the
example will work also when the same interface name is specified for
both the ovs-bridge and the ovs-port.

The functionality of the ibft settings plugin is now handled by
nm-initrd-generator. There is no need for it anymore, drop it.
Note that ibft called iscsiadm, which requires CAP_SYS_ADMIN to work
([1]). We really want to drop this capability, so the current solution
of a settings plugin (as it is implemented) is wrong. The solution
instead is nm-initrd-generator.
Also, on Fedora the ibft was disabled and probably on most other
distributions as well. This was only used on RHEL.

It's deprecated and off by default for a long time.
It is bad to automatically reload connection profiles. For example, ifcfg
files may consist of multiple files, there is no guarantee that we
pick up the connection when it's fully written.
Just don't do this anymore.
Users should use D-Bus API or `nmcli connection reload` or `nmcli
connection load $FILENAME` to reload profiles from disk.
Since we only compare that the HTTP response starts with the expected
response, we need to handle the empty expected response specially
(because, every response has "" as prefix).
So now if connectivity.response is set to "" (empty) we accept:
- HTTP status code 204. We ignore and accept any extra data that we
might receive.
- HTTP status code 200 and an empty (or no) body.
If the spec specifies only negative matches (and none of them matches),
then the result shall be positive.
Meaning:
[connection*] match-device=except:dhcp-plugin:dhclient
[connection*] match-device=except:interface-name:eth0
[.config] enabled=except:nm-version:1.14
should be the same as:
[connection*] match-device=*,except:dhcp-plugin:dhclient
[connection*] match-device=*,except:interface-name:eth0
[.config] enabled=*,except:nm-version:1.14
and match by default. Previously, such specs would never yield a
positive match, which seems wrong.
Note that "except:" already has a special meaning. It is not merely
"not:". That is because we don't support "and:" nor grouping, but all
matches are combined by an implicit "or:". With such a meaning, having
a "not:" would be unclear to define. Instead it is defined that any
"except:" match always wins and makes the entire condition to explicitly
not match. As such, it makes sense to treat a match that only consists
of "except:" matches special.
This is a change in behavior, but the alternative meaning makes
little sense.
If the user disabled systemd-resolved, two things seem apparent:
- the user does not want us to use systemd-resolved
- NetworkManager is not pushing the DNS configuration to
systemd-resoved.
It seems to me, we should not consult systemd-resolved in that case.
Try to locate an existing connection before creating a new one when
handling "nmcli device wifi connect". This allows WPA-Enterprise
networks to be activated this way, consistent with the comment that this
command is equivalent to clicking on an SSID in a GUI client.
Add a new CON_DEFAULT() macro that places a property name into a
special section used at runtime to check whether it is a supported
connection default.
Unfortunately, this mechanism doesn't work for plugins so we have to
enumerate the connection defaults from plugins in the daemon using
another CON_DEFAULT_NOP() macro.
Correct the spelling across the *entire* tree, including translations,
comments, etc. It's easier that way.
Even the places where it's not exposed to the user, such as tests, so
that we learn how is it spelled correctly.
Manually disconnecting a profile of course blocks autoconnect of the
same profile. Otherwise, the profile would likely re-activate right
away, which is clearly against the users intention. If the users just
want to re-activate the profile, they should issue `nmcli connection up`
instead, with does a full down and up cycle.
This is more interesting for profiles that have 'connection.multi-connect'
set to 'multiple'. Would you expect that manually deactivating such a
profile blocks autoconnect of the profile on all devices? Maybe
yes, maybe not. Currently that is indeed the case and autoconnect gets
blocked regardless of multi-connect.
The need for this is the following:
"ipv4.dhcp-client-id" can be specified via global connection defaults.
In absence of any configuration in NetworkManager, the default depends
on the DHCP client plugin. In case of "dhclient", the default further
depends on /etc/dhcp.
For "internal" plugin, we may very well want to change the default
client-id to "mac" by universally installing a configuration
snippet
[connection-use-mac-client-id]
ipv4.dhcp-client-id=mac
However, if we the user happens to enable "dhclient" plugin, this also
forces the client-id and overrules configuration from /etc/dhcp. The real
problem is, that dhclient can be configured via means outside of NetworkManager,
so our defaults shall not overwrite defaults from /etc/dhcp.
With the new device spec, we can avoid this issue:
[connection-dhcp-client-id]
match-device=except:dhcp-plugin:dhclient
ipv4.dhcp-client-id=mac
This will be part of the solution for rh#1640494. Note that merely
dropping a configuration snippet is not yet enough. More fixes for
DHCP will follow. Also, bug rh#1640494 may have alternative solutions
as well. The nice part of this new feature is that it is generally
useful for configuring connection defaults and not specifically for
the client-id issue.
Note that this match spec is per-device, although the plugin is selected
globally. That makes some sense, because in the future we may or may not
configure the DHCP plugin per-device or per address family.

Quote from `man NetworkManager.conf`:
When the default wired connection is deleted or saved to a new
persistent connection by a plugin, the device is added to a list in the
file /run/NetworkManager/no-auto-default.state to prevent creating
the default connection for that device again.
"/run" is obviously wrong. Fix it.

Already since 1.0.0 release and commit "3784678177 cli: create a connection
if none exist in 'nmcli dev connect' (rh #1113941)", device-connect can
also create a profile.
That is useful, in particular as opposed to
$ nmcli connection up ifname "$DEVICE"
which wouldn't create a profile (ever).
Document it.
We need to copy all introspection files to the same directory when
building the documentation.
Note that we only require Meson 0.44, but for the documentation at
least 0.46 is needed because of a new functionality of
gnome.gdbus_codegen(). In this way we can still build on Travis CI
(without documentation).
Even when the system resolver is configured to something else that
systemd-resolved, it still is a good idea to keep systemd-resolved up to
date. If not anything else, it does a good job at doing per-interface
resolving for connectivity checks.
If for whatever reasons don't want NetworkManager to push the DNS data
it discovers to systemd-resolved, the functionality can be disabled
with:
[main]
systemd-resolved=false
When a DNS plugin is enabled (like "main.dns=dnsmasq" or "main.dns=systemd-resolved"),
the name servers announced to the rc-manager are coerced to be 127.0.0.1
or 127.0.0.53.
Depending on the "main.rc-manager" setting, also "/etc/resolv.conf"
contains only this coerced name server to the local caching service.
The same is true for "/var/run/NetworkManager/resolv.conf" file, which
contains what we would write to "/etc/resolv.conf" (depending on
the "main.rc-manager" configuration).
Write a new file "/var/run/NetworkManager/no-stub-resolv.conf", which contains
the original name servers, uncoerced. Like "/var/run/NetworkManager/resolv.conf",
this file is always written.
The effect is, when one enables "main.dns=systemd-resolved", then there
is still a file "no-stub-resolv.conf" with the same content as with
"main.dns=default".
The no-stub-resolv.conf may be a possible solution, when a user wants
NetworkManager to update systemd-resolved, but still have a regular
/etc/resolv.conf [1]. For that, the user could configure
[main]
dns=systemd-resolved
rc-manager=unmanaged
and symlink "/etc/resolv.conf" to "/var/run/NetworkManager/no-stub-resolv.conf".
This is not necessarily the only solution for the problem and does not preclude
options for updating systemd-resolved in combination with other DNS plugins.

nm-initrd-generator scans the command line for options relevant to network
configuration and creates configuration files for an early instance of
NetworkManager run from the initial ramdisk during early boot.
