NMExportedObject now derives from GDBusObjectSkeleton, which is what
GDBusObjectManagerServer wants. The main GDBusConnection and each
private server connection now gets a new GDBusObjectManagerServer,
and exported objects are registered with that instead of individually
exporting each GDBusInterfaceSkeleton.
Previously exported objects were not referenced by the BusManager,
but instead removed from the exports hash via weak references. The
GDBusObjectManagerServer instead references exported objects, which
can make them live much longer than they did before.

Prevsiouly, the ifcfg-rh service and the regular NetworkManager
were both exported on the same D-Bus connection. That had the
effect, that on both services ("com.redhat.ifcfgrh1" and
"org.freedesktop.NetworkManager") all objects were visible.
This is also problematic later when we use GDBusObjectManager
for the org.freedesktop.NetworkManager service.
Export the ifcfg service on a separate bus connection.
One downside is, that we don't bother exporting the service
on the private socket and thus the service is not available
without D-Bus daemon.
Also, if the bus disconnects, we don't retry or recover. Instead
the D-Bus service is dead until restart.
Previously most objects were implicitly unexported when they were
destroyed, but since refcounts may make the object live longer than
intended, we should explicitly unexport them when they should no
longer be present on the bus.
This means we can assume that objects will always be un-exported
already when they are destroyed, *except* when quitting where most
objects will live until exit because NM leaves interfaces up and
running on quit.
If the current agent disappears and we already triggered the permission check
for it then the callback for that permission check will fire after we
progressed to the next agent:
# nmcli c --wait 0 up vpn
When another agent, such as GNOME Shell is registered, then get_done_cb() for
the nmcli will be called after we started the permission check for GNOME Shell,
resulting in an assertion fail:
get_done_cb: assertion 'call_id == parent->current_call_id' failed
Previsously, _LOGT() could be disabled at compile time. Thus it
was different then the other macros _LOGD(), _LOGI(), etc.
OTOH, _LOGt() was the macro that always was compiled in.
Swap the name of the macros. Now the upper-case macros are always
enabled, while the lower-case macro _LOGt() is enabled depending
on compile configuration.
Take a missing value in keyfile/ifcfg-rh as EUI-64 to keep the compatibility
with the old conneciton. Nevertheless, the new connections should default to
the RFC7217 addresses.
It might be that the user didn't supply the secrets in time and the dbus call
timed out. The agent should now hide the secrets dialog and we must let it know.

Initscripts do:
oldifs=$IFS;
IFS=';';
[ -n "${ETHTOOL_DELAY}" ] && /bin/usleep ${ETHTOOL_DELAY}

/sbin/ethtool $opts

IFS=$oldifs;
thus, we want to split on ';', otherwise we parse
"wol d;something else"
wrong.
Also, g_strsplit_set() returns multiple empty tokens. So
we must skip over empty tokens in case of "wol d".
The @use_password was wrong, because we would warn if sopass is specified
before wol:
"sopass AA:BB:CC:DD:EE:FF wol g"
More resilently handle wrong configurations:
"wol pu wol m" => gives m.
"wol pu wol" => should give NONE and warn (instead of "pu").
Also accept tab as separator.
Add a new 'ignore' option to NMSettingWired.wake-on-lan which disables
management of wake-on-lan by NetworkManager (i.e. the pre-existing
option will not be touched). Also, change the default behavior to be
'ignore' instead of 'disabled'.

Dracut when faced with an ipv6 only setup during kickstart will generate a ifcfg
file that sets the ipv4 address things to null but sets BOOTPROTO=static. This
makes network manager screw up because it expects an ipv4 address to be set.
Instead deal with this case by checking if we have any ipv4 addrs set, and if
not just disable ipv4. This fixes our inability to kickstart in our ipv6 only
clusters. Thanks,

Some initscripts variables can use "0" or "1" instead of more common
"yes", "no", for example REORDER_HDR.
And we also write REORDER_HDR=0|1 in writer.c, so we did not read REODER_HDR
correctly.
Fixes: ccea442504
The kernel defaults REORDER_HDR to 1 when creating a new VLAN, but
NetworkManager's VLAN flags property defaulted to 0. Thus REORDER_HDR was not
set for NM-created VLANs with default values.
We want to match the kernel default, so we change the default value for the
vlan.flags property. However, we do not want to change the flags for existing
connections if the property is missing in connection files. Thus we have to
update plugins for that. We also make sure that vlan.flags is always written
by 'keyfile' when the value is default. That way new connections have flags
property explicitly written and it will be loaded as expected.

For libnm library, "nm-dbus-interface.h" contains defines like the D-Bus
paths of NetworkManager. It is desirable to have this header usable without
having a dependency on "glib.h", for example for a QT application. For that,
commit c0852964a8 removed that dependancy.
For libnm-glib library, the analog to "nm-dbus-interface.h" is
"NetworkManager.h", and the same applies there. Commit
159e827a72 removed that include.
However, that broke build on PackageKit [1] which expected to get the
version macros by including "NetworkManager.h". So at least for libnm-glib,
we need to preserve old behavior so that a user including
"NetworkManager.h" gets the version macros, but not "glib.h".
Extract the version macros to a new header file "nm-version-macros.h".
This header doesn't include "glib.h" and can be included from
"NetworkManager.h". This gives as previous behavior and a glib-free
include.
For libnm we still don't include "nm-version-macros.h" to "nm-dbus-interface.h".
Very few users will actually need the version macros, but not using
libnm.
Users that use libnm, should just include (libnm's) "NetworkManager.h" to
get all headers.
As a special case, a user who doesn't want to use glib/libnm, but still
needs both "nm-dbus-interface.h" and "nm-version-macros.h", can include
them both separately.

Clone the connection upon activation. This makes it safe for the user
to modify the original connection while it is activated.
This involves several changes:
- NMActiveConnection gets @settings_connection and @applied_connection.
To support add-and-activate, we constructing a NMActiveConnection with
no connection set. Previously, we would set the "connection" field to
a temporary NMConnection. Now NMManager piggybacks this temporary
connection as object-data (TAG_ACTIVE_CONNETION_ADD_AND_ACTIVATE).
- get rid of the functions nm_active_connection_get_connection_type()
and nm_active_connection_get_connection_uuid(). From their names
it is unclear whether this returns the settings or applied connection.
The (few) callers should figure that out themselves.
- rename nm_active_connection_get_id() to
nm_active_connection_get_settings_connection_id(). This function
is only used internally for logging.
- dispatcher calls now get two connections as well. The
applied-connection is used for the connection data, while
the settings-connection is used for the connection path.
- needs special handling for properties that apply immediately
when changed (nm_device_reapply_settings_immediately()).

NMSecretAgent (and in turn NMAgentManager) used the @connection argument both
for the connection data, but also for the connection path. Detangle these, and
accept the path separate from the connection.
This makes NMSecretAgent and NMAgentManager truly operate on a plain
NMConnection, without the non-obvious requirement, that the path of the
connection must be set.
Refactor agent-manager to always invoke the complete function for
nm_agent_manager_get_secrets().
In general, the complete function is always invoked asnychronously
when starting the operation. On the other hand, when cancelling the
operation or disposing the manager with pending operations, we now
(always) synchronously invoke the callback.
This makes it simpler for the user to reliably cancel the request
and perform potential cleanup.
This behavior bubbles up through NMSettingsConnection and NMActRequest,
and other callers that make directly or indicrectly make use of
nm_agent_manager_get_secrets().
Instead of having the call_id of type guint32, make it an (opaque)
pointer type.
This has the advantage of strong typing and avoids the possiblity
of reusing an invalid integer (or overflow of the call-id counter).
OTOH, it has the disadvantage, that after a call_id is disposed,
it might be reused for future invocations (because malloc might
reuse the memory).
In fact, it is always an error to use a call_id that is already
completed. This commit also adds assertions to the cancel() calls
that the provided call_id is a pending call. Hence, such a bug
will be uncovered by assertions (that only might not tigger in
certain unlikely cases where a call-id got reused).
Note that for NMAgentManager, save_secrets() and delete_secrets()
both returned a call_id. But they didn't also provide a callback when
the operation completes. So the user trying to cancel such a call,
cannot know whether the operation is still in process and he cannot
avoid triggering an assertion.
Fix that by not returning a call-id for these operations. No caller
cared about it anyway.
For NMSettingsConnection, also track the internally scheduled requests
for so that we can cancel them on dispose.
The GATEWAY from /etc/sysconfig/network file is used as a default value when
no GATEWAY is in ifcfg file. However, we have to ignore that GATEWAY for
connections without static addresses. Otherwise such connections would be
invalid and would disappear after restart/reaload.
Some notes:
Putting GATEWAY into /etc/sysconfig/network is not recommended, because it
inherently belongs to the ifcfg file as it is a per-interface property.
The recommended practice is to specify GATEWAY in individual ifcfg files and
define DEFROUTE=no if the interface should not get the default route.
But we continue to read GATEWAY from /etc/sysconfig/network for compatibility
reasons.
