The config file can specify a dhclient script, which gets used instead
of what NM passes on the command-line. Make sure that script gets
ignored in the final dhclient config, because the script NM passes
is the script that needs to be used to pass data back to NM. People
may have old dhclient.conf files lying around that get picked up and
we don't want any script specified there to interfere.
GValueArray is deprecated. Unfortunately, it's part of our API right now,
so we have to keep it around for a while. But since it's deprecated, and
we want to know about *other* deprecations, we have to suppress deprecations
about GValueArray. Unfortunately using macros to do that (eg in
nm-gvaluearray-compat.h) exposes some compiler bugs due to the combination
of parentheses/braces and #pragma from G_GNUC_BEGIN_IGNORE_DEPRECATIONS,
resulting in warnings like:
nm-utils.c:920:9: error: expected expression before ‘#pragma’
Work around this by not trying to stuff what's now a macro (eg
g_value_array_get_nth) into what's already a macro (G_VALUE_TYPE).
There's probably a better way to do this...
Remove the HostnameThread stuff from nm-policy-hostname and just use
GResolver instead. Move the one remaining nm-policy-hostname function
into nm-policy.
Avoid warnings about GValueArray being deprecated by adding macros
that wrap G_GNUC_BEGIN_IGNORE_DEPRECATIONS /
G_GNUC_END_IGNORE_DEPRECATIONS around the GValueArray calls.
data_iface is the serial port over which PPP should be run, so
we need to preserve that and not overwrite it with the PPP interface
name. When reconnecting, pppd wants the TTY to run PPP over (eg the
ModemManager data_port like ttyUSB0) but if we overwrote that with
ppp0 on the last connection, that's extremely unhelpful and pppd will
fail to start.
When built with MM1 support, the restart handling code here would
fail for both old MM and new MM. The code should ignore the
name owner change even if the incoming bus name is *neither*
old MM nor new MM. It wasn't doing that.
Seems that NLM_F_CREATE isn't enough, we need to replace anything
that's already there. Oddly, this is even though we already cleaned
out anything that was already there.
Otherwise, priv->accept_ra_path would be NULL, which isn't very
useful and makes nm_utils_do_sysctl() angry. No reason we shouldn't
always create priv->accept_ra_path in the future though.

Add a "need_carrier" argument to nm_device_is_available(), to allow
distinguishing between "device is not available", "device is fully
available", and "device is available except for not having carrier".
Adjust various parts of NMDevice and NMManager to allow for the
possibility of activating a connection with :carrier-detect = "no" on
a device with no carrier, and to avoid auto-disconnecting devices with
:carrier-detect = "on-activate".
https://bugzilla.gnome.org/show_bug.cgi?id=688284
For settings corresponding to devices that have a :carrier property
(ie bond, bridge, infiniband, vlan, and wired), add a :carrier-detect
property specifying how that affects the connection:
yes: The connection can only be activated when the device
has carrier, and will be deactivated if the device loses
carrier (for more than 4 seconds).
no: The connection ignores carrier on the device; it can be
activated when there is no carrier, and stays activated
when carrier is lost.
on-activate: The connection can only be activated when the
device has carrier, but it will not be deactivated if the
device loses carrier.
https://bugzilla.gnome.org/show_bug.cgi?id=688284
Move some duplicated carrier-handling code into NMDevice (which can
introspect itself to see if it's a subclass that has carrier).
The "mostly ignore carrier" special handling for bridges and bonds is
now also handled as part of the NMDevice-level carrier handling.

The original used uuid_parse() but that function did not
work properly since the format of the machine-id is
not compatable with a real uuid. This patch adds a new
machine_id_parse() routine to correctly convert the
character string of hex digits to a 16 byte binary string.
nm_settings_connection_init() was calling nm_connection_set_path(),
but this was pointless since that would end up getting cleared by the
property's default value shortly after init() returned (and
claim_connection() depended on this). So remove that code.

24cda2bc broke the ability to set NMConnection:path back to NULL after
it had been set, as part of a hack to try to make
NMRemoteConnection:dbus-path work. Fix that by moving the hack
entirely into NMRemoteConnection.
https://bugzilla.gnome.org/show_bug.cgi?id=693829
In order to resolve NMRemoteConnection-valued properties, NMObject
needs to be able to create NMRemoteConnections. But NMObject assumes
that all the objects it will be creating have "dbus-connection" and
"dbus-path" properties. So add those properties to NMRemoteConnection,
aliasing the existing "bus" and "path" properties (and ensure that
whichever version gets set, we keep that value, rather than letting it
get overwritten by the NULL default value of the other one).
https://bugzilla.gnome.org/show_bug.cgi?id=693669
GObject creation cannot normally fail, except for types that implement
GInitable and take a GError in their _new() method. Some NM types
override constructor() and return NULL in some cases, but these
generally only happen in the case of programmer error (eg, failing to
set a mandatory property), and so crashing is reasonable (and most
likely inevitable anyway).
So, remove all NULL checks after calls to g_object_new() and its
myriad wrappers.

g_malloc(), etc, never return NULL, by API contract. Likewise, by
extension, no other glib function ever returns NULL due to lack of
memory. So remove lots of unnecessary checks (the vast majority of
which would have immediately crashed had they ever run anyway, since
g_set_error(), g_warning(), and nm_log_*() all need to allocate
memory).
