Some initscripts variables can use "0" or "1" instead of more common
"yes", "no", for example REORDER_HDR.
And we also write REORDER_HDR=0|1 in writer.c, so we did not read REODER_HDR
correctly.
Fixes: ccea442504
The kernel defaults REORDER_HDR to 1 when creating a new VLAN, but
NetworkManager's VLAN flags property defaulted to 0. Thus REORDER_HDR was not
set for NM-created VLANs with default values.
We want to match the kernel default, so we change the default value for the
vlan.flags property. However, we do not want to change the flags for existing
connections if the property is missing in connection files. Thus we have to
update plugins for that. We also make sure that vlan.flags is always written
by 'keyfile' when the value is default. That way new connections have flags
property explicitly written and it will be loaded as expected.

Don't handle master-ready at the beginning of stage2, but instead while
scheduling (and then possibly delaying the scheduling of stage2).
This seems more idiomatic:
When inside a stage and your part is done: call schedule-next-stage.
That is, always schedule the next stage, not the current one.
schedule-next-stage then might delay to really scheduling until the
device is ready for the next state.
Fixes: 85ac903bb8
During stage2, if the slave detected that it would need to wait for
the master, it would return FALSE (which removes the g-idle-handler).
However, it would not clear the activation-source, so later, when
the master becomes ready, its attempt to schedule stage2 again would
result in an error-log and the idle-handler would not be scheduled
again.

This is intentionally IPv4 specific since this is used for a quick fallback to
method=link-local -- something that's not needed for IPv6 since the link local
address is always there.

Otherwise the uninitializeded objects could be prematurely signalled if their
paths are seen twice in quick succession. This happens when you have ethernet
hardware and add an ethernet connection -- it's immediatelly added to
AvialableConnections and the property reload signals the object addition
before the NMRemoteSettings's GetSettings() finishes:
# nmcli c add type ethernet autoconnect no ifname '*'
(process:4610): libnm-CRITICAL **: nm_connection_get_id: assertion 's_con != NULL' failed
Connection '(null)' ((null)) successfully added.

No longer support disabling the global-dns configuration via the
"enable" option.
Instead, the user can put the entire dns-configuration in one separate
snippet, and disable it altogether with ".config.enable".
Support a new configuration option
[.config]
enable=<ENABLED>
for configuration snippets.
This new [.config] section is only relevant within the snippet itself
and it is not merged into the combined configuration.
Currently only the "enable" key is supported. If the "enable" key is
missing, it obviously defaults to being enabled. It allows snippets
to be skipped from loading. The main configuration "NetworkManager.conf"
cannot be skipped.
<ENABLED> can be a boolean value (false), to skip a configuration
snippet from loading.
It can also be a string to match against the NetworkManager version,
like "enable=nm-version-min:1.1,nm-version-min:1.0.6"
There are several motivations for this:
- the user can disable an entire configuration snippet by toggeling
one entry.
This generalizes the functionality of the global-dns.enable
setting, but in a way that applies to configuration on a per-file
basis.
- for developing, we often switch between different versions of
NetworkManager. Thus, we might want to use different configuration.
E.g. before global-dns options, I want to use "dns=none" and manage
resolv.conf myself. Now, I can use global-dns setting to do that.
That can be achieved with something like the following (not exactly,
it's an example only):
[.config]
enable=nm-version-min:1.1
[main]
dns=default
[global-dns-domain-*]
nameserver=127.0.0.1
Arguably, this would be more awesome, if we would bump our micro devel
version (1.1.0) more often while developing 1.2.0 (*hint*).
- in principle, packages could drop configuration snippets and enable
them based on the NetworkManager version.
- with the "env:" spec, you can enable/disable snippets by configuring
an environment variable. Again, useful for testing and developing.
This is effectively the same as nm_config_parse_boolean(). The difference is,
that "nm-config.c" is not available to the interface-helper, thus any
code used by interface-helper (like "NetworkManager.c") cannot use this
function.
Still don't drop nm_config_parse_boolean() entirely, because it's better
to have the explicit notion of parsing a string in the config-context.
I ended up not using the function. But I'd still keep this patch.
Allows to enable more-asserts more granularly.
Unfortunately, the old check was "${enable_more_asserts} == "yes", thus
we cannot extend "--enable-more-assert=level" because that would mean
that the same build script cannot set the option on both old and new
NetworkManager.
Thus, add a new option --with-more-asserts=level. If you put the
following in your build script, it will work as expected whether
you build a new or an old version of NetworkManager.
./configure --enable-more-asserts --with-more-asserts=5
The 'new-connection' signal of a GDBusServer is emitted by default
through an idle source and the actual message processing starts only
after a signal handler returns TRUE.
Thus, before the signal handler has the chance to run, the GDBus
worker thread may detect that the connection is closed and schedule
the delivery of the 'closed' signal through another idle source.
After the termination of the 'new-connection' handler, the 'closed'
handler is executed, which cancels the subscription to GDBus signals
before any message has been processed.
This looks like a bug in GDBusServer; to work around it, just delay
the close of connection to let the signal dispatch run first.

When activating for example a team device which is to be enslaved to a
bridge, nm_device_activate_stage1_device_prepare() will postpone
stage 2.
In that case, we didn't register the "master-ready" of the team
device and thus never progressed the slave from stage2.
Reproduce:
# nmcli connection delete t-br0
# nmcli connection delete t-team0
nmcli connection add type bridge con-name t-br0 autoconnect no ifname i-br0 ip4 192.168.177.100/24 gw4 192.168.177.1
nmcli connection add type team con-name t-team0 autoconnect no ifname i-team0
nmcli connection modify id t-team0 connection.master i-br0 connection.slave-type bridge
nmcli connection up t-team0
Otherwise I get the following error (iwhile building in Jenkins):

When a Wi-Fi is switched to AP mode, NMDeviceWifi forgets the AP scan list.
Later, when the device goes back to normal managed mode, the device was not
able to acquire the AP list again (for a long time), because the list is only
populated when a new BSS is signalled. And that could take very long or never
happen as the supplicant would have to lost the BSS and announce it later.
Fix the problem by announcing known BSSs as a response to ScanDone signal.
Testcase:
$ nmcli con add type wifi ifname wlan0 con-name my-wifi-ap autoconnect off ssid MYSSID
$ nmcli con modify my-wifi-ap wifi.mode ap ipv4.method shared
$ nmcli con up my-wifi-ap
$ nmcli con down my-wifi-ap
$ nmcli device wifi list

We now (since 3272ff6 libnm/libnm-glib: don't quit in the middle of asking for
secrets) always hook on the quit timer when NM asks the plugin if it needs
secrets. The timer is 20 seconds, which seems too short.
Let's make it three minutes. Don't bother adding another timer or using a
distinct timeout: it does no harm for the plugin to remain unused for three
minutes on a bus.
Another option would be to completely unhook it; however the plugin wouldn't
learn if the user cancelled the NM's secrets request and would remain unused
on the bus forever.
Modify the DNS manager to use the static global DNS configuration when
available. In addition, change DNS plugins interface to accept a new
argument for global configuration and add support for this new
parameter to the dnsmasq plugin.
