In some situations, objects might get used after being disposed, so
clear out their various priv fields so we don't try to access unreffed
objects, freed strings, etc.

No idea *why* they're NULL, unless perhaps that dbus-glib can't demarshal
the variants for some reason, but until we know why at least log the
problem so we know what properties the issue might affect.
If a client keeps the connection around after NMRemoteSettings is done
with it (and has emitted 'removed' for that connection) then the
RemoteSettings object was still registered to receive signals for
that connection. To prevent clients from being able to screw up
the RemoteSettings, disconnect any signals it may be listening for
when the connection is removed. (it should be doing that anyway)
The kernel wants there to be a default route over every RA-ed IPv6
interface, and it gets confused and annoyed if we remove that default
route and replace it with our own (causing it to effectively drop all
further RAs on the floor, which is particularly bad if some of the
information in the earlier RA had an expiration time).
So, rather than replacing the kernel's default route(s), just add an
additional one of our own, with a lower (ie, higher priority) metric.

This reverts commit dd0460697c.
The commit dd0460697c make nm_remote_settings_new()
create the NMRemoteSettings object synchronously. It fixed getting properties,
but undid the previous ability to initialize the object asynchronously.
It can be reverted now, because a4f450aa0b commit
ensure initialization in get_property() calls.
We need to do _nm_object_ensure_inited() /
_nm_remote_settings_ensure_inited() from the get_property()
implementations; in most cases, get_property() just calls another
accessor method (which will call _nm_object_ensure_inited()), but in a
few places, it reads priv->whatever directly, so we need to make sure
that it's valid.
Most of the stuff was done by 762df85234.
But to allow this piece of code:
from gi.repository import NMClient
nmclient = NMClient.Client()
print nmclient.get_active_connections()
we also need to set "dbus-path" property in NMClient constuctor(),
else parent NMObject is not properly constructed.
Bonding and InfiniBand are done. Bridging isn't, but after removing
the bonding and generic infrstructure parts of that section, there
wasn't really enough left to be worth keeping.
Reset all known bond options to their default values, not just the
ones that NMSettingBond allows overriding. Also, remove any bond
slaves that were already attached to the bond before we managed it.
Only update bond parameters that need to be updated. In particular,
setting either arp_interval or miimon to 0 has the side effect of also
setting the other one to 0, so don't do that if it's already 0.
Fix the handling of arp_ip_target; the sysfs arp_ip_target node does
not work the same way as the ifcfg BONDING_OPTS line (which is what
the code was assuming before).
Add NM_SETTING_BOND_ERROR_INVALID_OPTION and
NM_SETTING_BOND_ERROR_MISSING_OPTION error codes so we can better
distinguish errors in different options, and add checks for various
incompatible sets of options.
NMSettingBond sets the "miimon" option to "100" by default, but this
means that when reading in a saved configuration with "arp_interval"
set, it would end up with both "miimon" and "arp_interval" set, which
is invalid. Fix this by clearing "miimon" if "arp_interval" is set,
and vice versa.
libnl3 wants a destination address when setting a route, so just hand
it '::' with a address len of 0 so we don't get -NLE_MISSING_ATTR
when trying to set the IPv6 default route.
We need to set the interface's firewall zone before we kick off
any sort of IP configuration, so that rules for stuff like
DHCP are already handled by the time that these services are started.
Bindings (like GObject Introspection) almost always create objects
using g_object_new() by default and don't use our helper functions
like nm_client_new(). Thus we need to make sure that if the
object is created in that way, any property accesses or functions
that return properties ensure that the object is fully initialized,
which is what the _new() functions were supposed to do. In one
case in NMClient that was missing (getting active connections)
and wasn't happening at all in NMRemoteSettings, which are our two
entry points into libnm-glib.
This allows this python+GI sequence to return the expected active
connection list:
from gi.repository import NMClient
nmclient = NMClient.Client(dbus_path='/org/freedesktop/NetworkManager')
active = nmclient.get_active_connections()
print(active)
where previously it returned an empty list because the NMClient
wasn't fully initialized by the time nm_client_get_active_connections()
was called.
With the switch to IPv4 being allowed to fail by default we need
to clean up this old code a bit. PPP failure during IP config
should trigger a timeout, and the core code will handle whether
to fail the device completely or not. But if we got a valid IPv4
config and PPP failed later, the device gets failed. Previously
the device would just sit in IP_CONFIG state because now IPv4
defaults may-fail to TRUE, and when PPP failed the
nm_device_ip_config_should_fail() check would obviously not pass.
This should fix the warning "failed to allocate link cache" when a
new device is added. It doesn't affect WiFi operation, and the
code would fall back to non-nl80211 mechanisms of detecting whether
a device was wifi or not, so it corrects this check and quiets the
error message.
The kernel is broken for Ad-Hoc WPA, and creates the connections
as open connections instead. Yeah, eventually we can use
wpa_supplicant with RSN support, but for now we just have to
disable Ad-Hoc WPA because it's a problem to say we're creating
a protected network but then have the kernel not do that for
us. Will be re-enabled once all the necessary bits have been
fixed.
Note that Ad-Hoc WPA has been broken since at least 2.6.32 with
mac80211-based drivers, which is what most users will be using.
