The mesh and Wi-Fi companion share radio hardware and firmware resources
and you need both to exist for the mesh to function properly and to
ensure that the Wi-Fi and mesh sides cooperate correctly for scanning
and activation.
If the supplicant interface object never successfully initialized, remove
the pending action to prevent warnings about "pending action already added"
when supplicant_interface_acquire() adds the pending action again.
Just listen to manager signals all the time, but only respond to
them when necessary. Clean up companion detection to be a bit
clearer, and use nm_device_queue_state() so that we don't need
an idle handler when detecting the companion from a state change
handler.
to_string_link() logs link details and creates a new link to do this,
filling in the various filed in init_link(). init_link() attempts to
fill in the driver name, and might call ethtool to do that. Well,
ethtool API only accepts an interface name (which we don't have) and
not an ifindex (which we do have), and dies. Ensure that the ethtool
functions bail out instead of crashing if they don't get an interface
name.
Unfortunately, most callers of link_change() don't bother setting
ifindex or ifname on the link that ends up getting passed to
to_string_link(), because libnl doesn't require that when calling
rtnl_link_change(). Modify all callers to at least set the
ifindex so that to_string_link() has something useful to log.

There used to be many more members of the Supplicant struct, but now
that there are only three, collapse the struct into the NMDeviceWifiPrivate
struct, renaming them slightly at the same time to shorten the names.
Second, consolidate timeout cleanup since the two remaining timeouts
don't need their own cleanup functions.
Third, start_supplicant_connection_timeout() doesn't need its own
function since g_timeout_add() never returns 0, so we don't need to
check for it.
The only reason for the small struct was the idle handler, and the
only reason for the idle handler was to ensure that state was changed
from an idle handler. We've got nm_device_queue_state() to do that
for us now, so use it.

Older Intel "ipw" devices (ipw2100, ipw2200, and ipw2915) only gained
kernel rfkill subsystem integration with 2.6.33. Before then their
custom rfkill functionality had to be polled via sysfs. Since we now
require at least a 3.x kernel, remove this old code.

It's only used to keep the DHCPManager up-to-date with hostname changes,
and that can be accomplished in much less code by just having NMManager
set a hostname on the DHCPManager itself.
If IPv6 completes first it would emit the "up" dispatcher event with IPv6
details and move the device to ACTIVATED state. But if DHCPv4 was still
running, no dispatcher event would be emitted with the DHCPv4 information
until the first lease renew. Thus dispatcher scripts would not receive
DHCPv4 information for quite some time.
Ensure that if the other IP version completes first, that when the slower
method's DHCP completes, that it emits the appropriate dhcp4-change
or dhcp6-change event so that dispatcher scripts get the information
as soon as it's available.

By default pppd will suicide if there are 600s without traffic going through:
pppd[30575]: Terminating connection due to lack of activity.
pppd[30575]: Connect time 10.0 minutes.
pppd[30575]: Sent 0 bytes, received 0 bytes.
This is likely to happen when e.g. the system has both a mobile broadband
connection and an ethernet connection, as the ethernet will take the default
route.
So, avoid this behaviour by explicitly telling pppd not to exit if idle.
NetworkManager stopped touching /etc/hosts in late 2010 before the
NetworkManager 0.8.1 release. The code in nm-policy-hosts.c's only
purpose is to remove any of the entries that NetworkManager added long
ago.
I think we're at the point where people have already upgraded to
NetworkManager 0.8.1 or later and thus this code would be a NOP. The
only risk is that some stale /etc/hosts entries will be left if you
upgrade from NM 0.8 or lower to anything higher than that.
FWIW, Ubuntu Lucid (10.04) ships NM 0.8.0 and SLES11 ships NM 0.7.0, so
if users of these distros upgraded to a later NetworkManager they might
run into the stale entries issue if we remove this code from NM. But
given how old these distros are, it seems unlikely that users will do a
direct upgrade to something 4+ years newer...

When WWAN airplane mode is enabled, set modems to low power state to
ensure they are in airplane mode if either (a) the machine does not
have an rfkill switch, or (b) the modem is not tied to any rfkill
switch (eg, external USB/SDIO/etc).
If the given PIN was wrong, we really don't want to try that PIN
again automatically because it might lock the SIM. To ensure that
doesn't happen, disable autoconnect so that the user must manually
request reconnection.
(this doesn't fix auto-connect-with-a-wrong-PIN completely, as
autoconnect is reset when resuming from sleep, but it's a start)
Determining when the NMDeviceModem is available and when different
connections are available is easier if the modem's state is tracked,
instead of using the separate Enabled and Connected properties.
These properties could not accurately represent the SIM lock state
and prevented NetworkManager from making the modem available for
auto-activation when locked, even if a PIN was available.
In this new scheme, the NMDeviceModem is UNAVAILABLE when the
ModemManager modem state is FAILED, UNKNOWN, or INITIALIZING. It
transitions to the NM DISCONNECTED state when the modem has finished
initializing and has not failed.
Once the NMDeviceModem is in DISCONNECTED state it can be activated
even if the SIM is locked and a PIN is required; the PIN will be
requested when starting activation, either from the connection itself
or via a secrets request. This makes auto-activation of WWAN
connections possible.
This also allows us to consolidate code dealing with modem enable/disable
into the base NMModem class using the modem state, and to log more modem
information for debugging purposes.
Since the ModemManager enabled/disabled state is a user-changable
one, and since NM can enable the modem when starting a connection,
allow modems to be available for activation whenever they are not
in airplane mode. This makes WWAN autoconnect=true connections
actually autoconnect.
If the first connection fails during ModemManager setup for fatal
reasons (missing SIM, bad PIN, not registered), autoconnect will
be blocked for that connection until activation is manually
requested and succeeds.
rfkill handling should only pay attention to actual rfkill, since
rfkill is global but the modem management service state is per-device.
Thus calculating a global state from multiple devices is very
likely to get things wrong.
Remove all of the code that used to handle that sort of thing,
which means removing the 'enable-changed' signal from the Modem
device, since now nothing external to the modem device should
need to care whether it's enabled internally or not.
Poke the kernel's WWAN rfkill state when the user changes our
WWANEnabled property, the same as we do for WiFi. Also restore
saved WWAN state on startup, as we do for WiFi. No good reason
why WWAN should be different here.
When adding the same addresses from different sources, we want to
preserve the times with the later expiry . If the new address comes
from the kernel itself, we treat it specially and prefer the times
from other sources.

This compares two addresses and returns which one has a longer
remaining life (i.e. a later expiry timestamp).

Especially the calculation of timestamps is identicall for addresses.
By creating a "base struct", we can use the same code for that, because
NMPlatformIP4Address and NMPlatformIP6Address can now both be treated as
NMPlatformIPAddress (and the same for routes).

In case of DHCP4, DHCP6 and/or SLAAC, delay "startup complete" until
both IPv4 and IPv6 are ready. This especially has an effect on
nm-online/NetworkManager-wait-online.service, which blocks until
configuration of both IPv4 and IPv6 is ready.
We queue a pending_action when automatic configuration starts and
remove it again, when we receive an address. Before, "startup complete"
was reached when either one of the two IP protocols was configured.

dfe194ee made it so that we don't use "public suffixes" as resolv.conf
search domains (eg, we don't add "search com" if the hostname is
"example.com"). However, if this results in us writing a resolv.conf
with no "search" line at all, then the resolver will fall back to
using the parent domain of the hostname as a search domain anyway,
thwarting us.
To fix that, use the domain itself as a search domain in this case,
since that's likely to be the expected behavior anyway. (And even if
it's not, there doesn't appear to be any way to block the resolver
from using the hostname's parent domain as a search domain unless we
specify at least one search domain ourselves.)
https://bugzilla.gnome.org/show_bug.cgi?id=729137
resolv.conf(5) says:
The domain and search keywords are mutually exclusive. If more than
one instance of these keywords is present, the last instance wins.
NM always writes out a "search" line if it writes a "domain" line, so
the "domain" line is always a no-op. So drop it.
