Split a base NMSettingIPConfig class out of NMSettingIP4Config and
NMSettingIP6Config, and update things accordingly.
Further simplifications of now-redundant IPv4-vs-IPv6 code are
possible, and should happen in the future.
Add key-value attributes to NMIPAddress and NMIPRoute, and use them to
store IPv4 address labels. Demote NMSettingIP4Config:address-labels to
a D-Bus-only property, and arrange for :addresses setter to read the
labels out of that property when creating the addresses.
Merge NMIP4Address and NMIP6Address into NMIPAddress, and NMIP4Route
and NMIP6Route into NMIPRoute. The new types represent IP addresses as
strings, rather than in binary, and so are address-family agnostic.
Missing initializers together with automatic cleanup seem to annoy GCC's
-Werror=maybe-uninitialized, breaking the --enable-more-warnings=error
builds.
We must also remove -Waggregate-return from m4/compiler-warnings.m4 because systemd
uses aggregate return (correctly) in a couple cases, and we cannot keep single-level
makefiles and override aggregate-return only for the systemd sub-library.
This client currently only supports DHCPv4 because the base systemd code
does not yet fully support DHCPv6.
The systemd code was modified to add "#if 0 /* NM_IGNORED */"
around lines that cause problems for compilation or code that is
not actually used in the library.
An adaptation layer (nm-sd-adapt) was added for glue between
systemd functions and NetworkManager, but changes to the actual
systemd code have been kept to a minimum.
The sd_event/sd_event_source functions of systemd have been
re-implemented on top of the GLib main loop.
client->secs wasn't getting set in the REBOOT state, causing
an assertion. REBOOT should work the same way as INIT, per
RFC 2131:
secs 2 Filled in by client, seconds elapsed since client
began address acquisition or renewal process.
REBOOT is necessary because many DHCP servers (especially on
home routers) do not hand back the same IP address when in
response to a DISCOVER packet, even if the same client ID is used.
The raw socket sd_event_source used for DHCP server solicitations
was simply dropped on the floor when creating the new UDP socket
after a lease has been acquired. Clean it up properly so we're
not still listening and responding to events on it.
Non-ethernet interface types use different client identifier formats,
plus when doing DHCPv4 and DHCPv6 on the same interface, the client
identifier should be related per RFC 4361. Thus let the caller
override the existing MAC-based client identifier if necessary.
The plugin can indicate that this connection can persist across link
changes and other connectivity dropouts by passing this option
back in the SetConfig() calls.
If the VPN re-enters the STARTING state to indicate that it has
disconnected from the VPN server and is trying to reconnect, change
the VPN connection's state to indicate that connectivity may be
limited. Wait for the VPN to provide updated IP configuration
information from the reconnect to change back to the ACTIVATED
state.
This property will indicate that the user wishes the VPN connection
to stay active until explicitly disconnected, even across link changes
or other interruptions.
They are defined as gint32 but are assigned a guint32 value and
then immediately passed back to the caller of _address_get_lifetime()
as guint32. They can never be negative, and may receive values
greater than G_MAXINT32, so they should be unsigned.
When the DHCP server address is not on the same subnet, we used
to add a /32 route to the server IP address via the gateway.
Do not add this route, if we already got a direct route from DHCP.

Make LOGD_ALL and LOGD_DEFAULT members of the enum instead

NMIP4Configs and NMIP6Configs are never supposed to contain a default
route, and thus nm_platform_ip6_route_sync() should never have to deal
with one. Unfortunately, if it *does* get passed a default route, it
will add it even if it was already there. This will result in an
RTM_NEWROUTE notification, which will cause NMPlatform to emit
ip6-route-changed, which will result in NMDevice doing some work and
then calling nm_ip6_config_commit(), which will result in NMIP6Config
passing the same list of routes to nm_platform_ip6_route_sync() again,
including the default route, which will cause NMPlatform to add the
route again...
(Something eventually causes this cycle to get broken, but it starts
up again the next time NM receives an RA.)
Fix this by having the route_sync() functions never add/modify the
default route (They were already not deleting it.)
If the router sends an RA with an RDNSS or DNSSL lifetime of "0", that
means to immediately stop using the corresponding server/domain name.
NMLNDPRDisc knew this, but messed up its handling of it, and so if
this happened, it might end up sending out an RS to get new data every
0 seconds...
(Noticed while investigating bgo 735325, though it turned out to be
irrelevant there.)
The warning -Wstrict-prototypes was disabled by commit
db9b1df0e4 .
Enable it again, but avoid warnings for WiMax SDK by explicitly disabling the
compiler warning where needed.
Apparently clang does not produce a warning for -Wstrict-prototypes,
hence we don't need a clang specific #pragma.

nm_setting_verify() took a GSList of other NMSettings, but really it
would just be simpler all around to pass the NMConnection instead...
This means that several formerly NMSetting-branded functions that
operated on lists-of-settings now get replaced with
NMConnection-branded functions instead.
Add nm-core-types.h, typedefing all of the GObject types in
libnm-core; this is needed so that nm-setting.h can reference
NMConnection in addition to nm-connection.h referencing NMSetting.
Removing the cross-includes from the various headers causes lots of
fallout elsewhere. (In particular, nm-utils.h used to include
nm-connection.h, which included every setting header, so any file that
included nm-utils.h automatically got most of the rest of libnm-core
without needing to pay attention to specifics.) Fix this up by
including nm-core-internal.h from those files that are now missing
includes.
If the DHCP server happens to send "0.0.0.0", which you see with
some consumer gear that only has one nameserver set, don't warn
because we know it's bogus.
Also rename the copy & pasted 'searches' variable to what it's
actually used for.
Code outside of libnm-core/ should not include the private headers.
nm-core-internal.h should be used instead.

This can be triggered by stopping the DBUS service. The assertion happens
because when the supplicant stops (due to the name-owner-change, which is triggered
because dbus-daemon quit), the supplicant manager sets all supplicant interfaces
to DOWN state so that they can be cleaned up. That does two things:
1) calls supplicant_interface_acquire() to attempt to re-launch wpa_supplicant
in case wpa_supplicant segfaulted
2) moves the NMDevicWifi to UNAVAILABLE state because the supplicant is gone,
the device is no longer usable and we must terminate the connection and wait
for the supplicant to come back
But #2 also ends up calling supplicant_interface_acquire(), because that's what
we want to do when the NMDeviceWifi is first managed (at startup) and when the
supplicant dies. The code just doesn't differentiate between the two cases.
To fix this, just allow duplicate "waiting for supplicant" pending
actions, which is fine because the operation doesn't care about strict
added/removed sequencing.
