lease_to_ip6_config() calls the GString temporary buffer "str".
That makes sense, use the same name in lease_to_ip4_config().
For that, we have to rename other local variables too.
Don't have pending asynchronous requests in parallel, like setting
"ProcessCredentials" and "Start", or "Cancel" and "Start".
Instead, "Start" is only scheduled after "ProcessCredentials" completed
and "ProcessCredentials" is only scheduled after "Cancel" completed.
Also, handle the async response of these requests. For one, to achive the
chaining mentioned above and to log what happens and possible errors.
Upon new enrollment, a previously created GDBusProxy is now reused,
where the first operation is to Cancel the previous action.
Also, consistently <trace> log what is happening.
Not doing all of this is less lines of code. It's also simpler, and
faster. But in my opinion, it is (usually) better to check and wait for
return values, instead of firing off async requests uncontrolled. It
allows us to better know where we are and to log about each individual
step. This also makes all operations cancellable.
Undoubtedly, correctness and handling failures conflicts with simplicity
in this case -- or at least: what I think is "correctness" conflicts.
When IPv4 addresses are synchronized to platform, the order of IPv4
addresses matters because the first address is considered the primary
one. Thus, nm_ip4_config_capture() should put the primary address as
first, otherwise during synchronization addresses will be removed and
added back with a different primary/secondary role.

Since commit 2b51d3967 "device: merge branch 'th/device-mtu-bgo777251'",
we always set the MTU for certain device types during activation. Even
if the MTU is neither specified via the connection nor other means, like
DHCP.
Revert that change. On activation, if nothing explicitly configures the
MTU, leave it unchanged. This is like what we do with ethernet's
cloned-mac-address, which has a default value "preserve".
So, as last resort the default value for MTU is now 0 (don't change),
instead of depending on the device type.
Note that you also can override the default value in global
configuration via NetworkManager.conf.
This behavior makes sense, because whenever NM actively resets the MTU,
it remembers the previous value and restores it when deactivating
the connection. That wasn't implemented before 2b51d3967, and the
MTU would depend on which connection was previously active. That
is no longer an issue as the MTU gets reset when deactivating.

When running one of:
nmcli device wifi list ifname wlan0
nmcli device wifi connect ... ifname wlan0
nmcli wrongly adds the device name to the output.
Do the completion only when requested.

- don't use assert but be more graceful with g_return_if_fail().
- in case of failure, don't log a debug message after the warning.
One message is sufficient, drop "pppd pid %d cleaned up".
- print GPid type as long long.
- increase log level to warning. pppd dying unexpectedly warrants a
warning.
ppp_exit_code() does too much or too little. Either it should log
about all reasons why pppd exited, including signals, or it should
just do the status to string conversion. Split it.
It's useless (and in some cases also harmful) to commit the
configuration to update the default route metric when the device has
no default route. Also, don't commit configuration for externally
activated devices.

Don't log in a function that basically just inspects state, without
mutating it. Instead, pass the reason why a connection could not be
generated to the caller so that we have one sensible log message.
The device's RECHECK_ASSUME signal has only NMManager as subscriber
and it immediately calls recheck_assume_connection().
With the previous commit, recheck_assume_connection() always logs
a debug message, so we don't need this duplicate message anymore.
Originally 850c977 "device: track system interface state in NMDevice",
intended that a connection can only be assumed initially when seeing
a device for the first time. Assuming a connection later was to be
prevented by setting device's sys-iface-state to MANAGED.
That changed too much in behavior, because we used to assume external
connections also when they are activated later on. So this was attempted
to get fixed by
- acf1067 nm-manager: try assuming connections on managed devices
- b6b7d90 manager: avoid generating in memory connections during startup for managed devices
It's probably just wrong to prevent assuming connections based on the
sys-iface-state. So drop the check for sys-iface-state from
recheck_assume_connection(). Now, we can assume anytime on managed,
disconnected interfaces, like previously.
Btw, note that priv->startup is totally wrong to check there, because
priv->startup has the sole purpose of tracking startup-complete property.
Startup, as far as NMManager is concerned, is platform_query_devices().
However, the problem is that we only assume connections (contrary to
doing external activation) when we have a connection-uuid from the state
file or with guess-assume during startup.
When assuming a master device, it can fail with
(nm-bond): ignoring generated connection (IPv6LL-only and not in master-slave relationship)
thus, for internal reason the device cannot be assumed yet.
Fix that by attatching the assume-state to the device, so that on multiple
recheck_assume_connection() calls we still try to assume. Whenever we try
to assume the connection and it fails due to external reasons (like, the connection
no longer matching), we clear the assume state, so that we only try as
long as there are internal reasons why assuming fails.

The state file should only be read initially when NM starts, that is:
during NMManager's platform_query_devices().
At all later points, for example when a software device gets destroyed
and re-realized, the state file is clearly no longer relevant.
Hence, pass the set-nm-owned flag from NMManager to realize_start_setup().
This is very much the same as with the NM_UNMANAGED_FLAG_USER_EXPLICT flag,
which we also read from the state-file.
curl must bind to the interface that has IP configuration, not the
underlying device. Without this commit, connectivity check fails on
certain connection types (PPPoE, WWAN).

Don't crash if the bond mode can't be read from sysfs - for example
when the interface disappears. The generated connection will be bogus,
but at that point it doesn't matter because the in-memory connection
will be destroyed.

Let's explicitly unexports on dispose(). Probably that already
happened, because NMExportedObject asserts that it is unexported
during !quitting.
During quitting, we probably don't tear down the manager.
Anyway, we should always unexport.
nmcli closes its stdout when spawning the pager and thus, in editor
mode, nothing is printed once the pager terminates. For an interactive
mode like the editor, the pager seems not suitable, disable it.
Fixes: 24c079e4b2
After a daemon restart, any software device is considered !nm-owned,
even if it was created by NM. Therefore, a device stays around even if
the connection which created it gets deactivated or deleted.
Fix this by remembering the previous nm-owned state in the device
state file.
