Sometimes cause the cache not to refill with all interfaces,
meaning NM sometimes got the wrong carrier state from the
kernel which prevented NM from taking over existing connections.
Automatic IPv6 configuration is handled by the kernel, but to
integrate it properly with NetworkManager, we need to watch what the
kernel does to see whether or not it was successful (so that we can
let the user know if there is no IPv6 router present, for example).
NMIP6Manager takes care of this.
Found by Ricardo Salveti de Araujo <ricardo.salveti@openbossa.org>
The link cache was updated immediately, but the carrier state signals
were emitted a lot later, when the cache data was already stale. So
just update the cache at the same time we emit the signals. The
carrier-state-request stuff wasn't originally converted to deferred
for any netlink-specific reason, just to smooth the initial device
creation process in NM.
We really have wanted to use IFF_LOWER_UP since 2.6.17 for carrier
status, since that's tied to netif_carrier_ok()/netif_carrier_on() in
the kernel. See kernel commit b00055aacdb172c05067612278ba27265fcd05ce
for the introduction of IFF_LOWER_UP.

Fix mishandling of netlink error floods (rh #459205, novell #443429, lp #284507)
* src/nm-netlink-monitor.c
- Remove bits for using a non-default GMainContext, which weren't used
- (nm_netlink_monitor_error_handler): don't leak the GError, and report
the actual error code
* src/NetworkManager.c
- (nm_error_monitoring_device_link_state): disconnect error handler when
an error flood occurs to avoid pegging the CPU

Fix Linus' bug in rh #134886
* src/nm-device-802-3-ethernet.c
- (constructor): request initial carrier state
* src/nm-netlink-monitor.c
- (nm_netlink_monitor_request_status): schedule emission of carrier
signals after refilling the link cache. Because the refill is a
synchronous operation, the normal message hander won't get called
since libnl has already consumed the messages.
- (deferred_emit_carrier_state): emit carrier states from an idle handler

Convert to using interface indexes as the primary method of identifying
devices inside NetworkManager. Indexes are (?) stable, but devices can
be renamed at any time. Device object paths now refer to the device
index rather than the name, and you can map those two manually if you like
by looking in the /sys/class/net/<name>/ifindex file. Also moves most
netlink-related code to nm-netlink.c, and cleans up nm-netlink-monitor.c
to use interface indexes rather than names.

Threading removal related cleanups:
- Use the glib default main context. Remove the device main context
member from NMDevice, and the main_context member from NMData. Change
all the idle and timeout scheduler functions to use plain
g_idle_add() and g_timeout_add().
- As a side-effect of the first change, nm_dbus_manager_get() no longer
takes an argument; fix that up too.
- Remove all locking, which is useless since we no longer use threads. For
example, nm_get_device_by_iface_locked() has been removed. The global
device list lock, the AP List lock, and all static locks in
NetworkManagerPolicy.c have been removed. The locking utility functions
in NetworkManagerUtils.c have also been removed.
- Other cleanups in spacing and code style

* Kill dhcpcd. We now use "dhcdbd", a dbus daemon that controls dhclient.
This means that NetworkManager shouldn't have DHCP issues anymore. It also
means you need dhcdbd, which you can get here (get the latest one):
http://people.redhat.com/jvdias/dhcdbd/
Technically NetworkManager can use any DHCP daemon that uses the same DBUS
interface as dhcdbd.
* Rewrite device activation to facilitate the new DHCP infrastructure and
future improvements. Its now "activation request" based, ie there is a single
activation request composed of the device, access point, and other info which
follows the entire activation process. There are 5 stages of the activation
process which correspond to:
1) Device preparation
2) Device configuration (bring it up, set ESSID/Key/etc)
3) IP Config Start (fire off DHCP if we're using it)
4) IP Config Get (grab config from DHCP or static config files)
5) IP Config Commit (set device's IP address, DNS, etc)
Note that there is no longer a "scanning" step, since the access point must
be known _before_ activation starts. If the access point drops out or does
not exist for some reason, the entire activation process fails and must be
restarted for a different access point or device.
