GVariantBuilder doesn't care if you give it multiple dict entries with
the same key. But that causes duplicate dict entries in the legacy
D-Bus PropertiesChanged signals that NM emits. So instead go back to
a hash table to ensure that any previous value is dropped in favor of
the new one.
When porting to GDBus property change notifications were converted from a
hash table to a GVariantBuilder. GVariantBuilder doesn't care about
duplicated properties in the dict so each g_object_notify() will add
an additional item with possibly different values:
signal time=1458571005.592811 sender=:1.10 -> destination=(null destination) serial=64451 path=/org/freedesktop/NetworkManager; interface=org.freedesktop.NetworkManager; member=PropertiesChanged
array [
dict entry(
string "ActiveConnections"
variant array [
object path "/org/freedesktop/NetworkManager/ActiveConnection/19"
object path "/org/freedesktop/NetworkManager/ActiveConnection/18"
object path "/org/freedesktop/NetworkManager/ActiveConnection/15"
object path "/org/freedesktop/NetworkManager/ActiveConnection/0"
]
)
dict entry(
string "ActiveConnections"
variant array [
object path "/org/freedesktop/NetworkManager/ActiveConnection/24"
object path "/org/freedesktop/NetworkManager/ActiveConnection/19"
object path "/org/freedesktop/NetworkManager/ActiveConnection/18"
object path "/org/freedesktop/NetworkManager/ActiveConnection/15"
object path "/org/freedesktop/NetworkManager/ActiveConnection/0"
]
)
]
Fix that by not emitting notify events for the manager's ActiveConnections
property until the property has actually been updated in active_connection_add().
The unexport also isn't required for VPN connections since it will get
unexported when it's disposed after _internal_activation_failed() gets called.
We cannot simply compare the single values of option hashes to match
connections because some keys are equivalent to others and also
because keys having a default value should be ignored.
Add the compare_property method to implement custom comparison logic.
When a value of a TYPE_BOTH option is read back from kernel it
contains both string and numeric values ("balance-rr 0"), so we must
chop off the number before adding the option to the setting. Also
change the default values of options to the string form so that the
option matching logic works.
The bond 'arp_ip_target' option contains a list of comma-separated IP
addresses; but comma is also used to separate options and so at the
moment it is not possible to specify multiple IPs as the command
$ nmcli c m b1 bond.options \
mode=0,arp_interval=1,arp_ip_target=1.1.1.1,2.2.2.2
interprets 2.2.2.2 as the next option.
Allows spaces to be used as separators for the IPs of the
'arp_ip_target':
$ nmcli c m b1 bond.options \
"mode=0,arp_interval=1,arp_ip_target=1.1.1.1 2.2.2.2"
This can regularly happen when a virtual device depends on a parent/master
that is not yet created. We will retry later when the parent is ready, so
logging a warning about it is wrong and confusing.
The name_owner_chagned() unregisters the agent if NetworkManager goes away and
nmc_cleanup() also tries to unregister an agent, resulting in an assertion
failure:
# nmcli c up conn666
<daemon terminates>
Error: Connection activation failed: Message recipient disconnected from message bus without replying
(process:8746): libnm-CRITICAL **: nm_secret_agent_old_unregister: assertion 'priv->registered == TRUE' failed
_internal_unregister() already contains a priv->registered check and raising an
error on duplicate unregister attempt from a daemon after a restart is not a
problem either, since nmc_cleanup() doesn't care about the error returned
on teardown anyway.
We actually don't want to understand these options unless the legacy
*-slave types are used. The properties should be used directly instead.

This basically undoes most of what has been done in commit 00e0fffea2.
If we want to ensure that we create only one single instance of
NMPolicy, just don't create multiple instances. The nm_policy_new()
method should not be restriced and behave like other *new() functions
and create a new object as requested.
Add internal functions _nm_connection_replace_settings() and
_nm_connection_new_from_hash() that cannot fail.
Altough they are not public API, we have to expose them via
libnm-util.ver so that they can be used from libnm-glib.
Warnings aren't great, especially if they can realistically be triggered
by a newer NetworkManager version. Just accept what we can and ignore
the rest silently.
There is no excuse for clients to send connections to NetworkManager
that have invalid/unknown fields. Just reject them.
This is a dangerous change, because we might now reject connections
that we were accepting previously. Who know what clients were sending
and it used to work.
AddAndActivateConnection is allowed to provide an incomplete connection
that will be completed by NetworkManager. That is, a connection that
does not verify.
But we still want to catch invalid properties or unknown setting types.
Thus, we want to reject invalid partial connections.
This possibly rejects invalid requests from clients that were accepted
before. Thus this change has the potential to break misbehaving clients.

As Reapply() is new API in nm-1-1, there is no problem with backward
compatibility.
Relax our error checking which will allow us to try harder to
make the best out of whatever NetworkManager sends us.
Also, drop the g_warning(). First, now we really don't expect this
function to fail. And even in that case, raising a g_warning() from
the library is not very friendly to the user of libnm.
When we receive a connection from NetworkManager it is not guaranteed
that the connection verifies. For example, if the current libnm version
is older then the NetworkManager version.
Be more accepting and don't do any verification of the connection.
For NMVpnPluginOld this change is uncritical, because there are probably
no users of this API anyway.
NMVpnServicePlugin is new API since nm-1-1. However, this API is already
strongly used by all the plugins we ported over. So this change is
affecting them.
This should only matter if libnm's and NetworkManager's version differ,
because NetworkManager just doesn't send out an invalid connection. It
actually only matters if NetworkManager is a newer version and sends an
invalid connection to the client. That is anyway badly tested and probably
this changes rather improves compatibility than breaking existing users.

This is a change in behavior in that we accept also invalid connections
and pass them down to the sub-classes.
Normalizing means that we fail on invalid connections.
Which can happen when the server is newer than the libnm
version. We just want to return whatever we can. The
caller should make sense of this.
This makes libnm more accepting and thus is not going to break
existing applications. Also, nm_device_get_applied_connection()
is new API since nm-1-1.
No actual change, let's just not directly call nm_simple_connection_new_from_dbus().
Instead, add a wrapper to define in once place the flags we use for loading the
connection.
