944ff9f9dc manager: create a virtual device only if the connection can autoconnect
The autoconnection for virtual devices currently works in two
phases. First we detect that there is suitable profile that can
autoconnect and we realize the device. Then, when the device becomes
'disconnected', autoconnect kicks in and starts the activation.

However, if autoconnect is blocked for a device, currently we do step
1 without step 2, leaving a stale interface around. Fix this by also
checking that autoconnect is not blocked during step 1.

3381299562 ovs: check state before starting ip configuration after link change
When the link becomes available, check that the device is in the
ip-config state before starting ip configuration. Also, reset the

bd9b253540 all: rename time related function to spell out nsec/usec/msec/sec
The abbreviations "ns" and "ms" seem not very clear to me. Spell them
out to nsec/msec. Also, in parts we already used the longer abbreviations,
so it wasn't consistent.

490c46e527 meson/build: avoid using ternary as it breaks older meson
See mesonbuild issue 5003.

Oddly, this isn't inside a method call, while we use ternaries
inside a method calls otherwise. Anyway, workaround this and
avoid the crash.

The issue happens because glib passes the "atomic" argument to

  __atomic_compare_exchange_n ((atomic), &gapcae_oldval, (newval), FALSE, __ATOMIC_SEQ_CST, __ATOMIC_SEQ_CST)

without cast, and clang 9 seems to be picky about const pointers.
Add our own version of the macro that does better casts while also having
better compile time checks for valid arguments.

64f103416f clients/tests: support Util.replace_text_sort_list() helper
This will be necessary to sort a list of text that contains text to
replace. The use case is to get all UUIDs from the server, but some
of these UUIDs are dynamic. So, in order to have a fixed sort order,
we need to handle sorting the list, based on the replacement.

1191eba15a device: always allow reapply of MTU from wired setting
Many device types take the MTU value from the wired setting; usually
they don't implement the can_reapply_change() method and so the MTU
can't be changed with the Reapply() API.

Instead of implementing the method for all such devices to support the
same property (adding a lot of duplicated code), add a check in
NMDevice to allow the reapply of MTU when we recognize that the device
uses the MTU from the wired setting.

Device types can still decide to implement can_reapply_change() and
support whatever properties they want, even from the wired setting.

62c9d8c109 config: return GPtrArray with warnings from internal read_entire_config() function
The underlying GPtrArray that we use to construct the list of warnings
is more useful than the strv array. For the internal function, don't
let it return the strv array but instead take (and fill) the warnings
as GPtrArray. There is no difference in practice, because also
previously we would always create an empty GPtrArray.

a0a5b0b2f5 core: add main.auth-polkit option "root-only"
We always build with PolicyKit support enabled, because it has no
additional dependencies, beside some D-Bus calls.

However, in NetworkManager.conf the user could configure
"main.auth-polkit" to disable PolicyKit. However, previously it would
only allow to disable PolicyKit while granting access to all users.

I think it's useful to have an option that disables PolicyKit and grants
access only to root. I think we should not go too far in implementing
our own authorization mechanisms beside PolicyKit (e.g. you cannot
disable PolicyKit and grant access based on group membership of the
user). However, disabling PolicyKit can be useful sometimes, and it's
simple to implement a "root-only" setup.

Note one change is that when NetworkManager now runs without a D-Bus
connection (in initrd), it would deny all non-root requests. Previously
it would grant access. I think there should be little difference in
practice, because if we have no D-Bus we also don't have any requests to
authenticate.

d27fcd0754 build/meson: allow configuring default for main.auth-polkit setting
We always build PolicyKit support, because it merely depends on some
D-Bus calls. However, there are two things to configure:

 - the default value for main.auth-polkit in NetworkManager.conf. This
   is now called "-Dconfig_auth_polkit_default=$VAL".

 - whether to install the policy file. This is called "-Dpolkit=$VAL".

These settings are mostly independent, so add "config_auth_polkit_default" to
make the default explicitly configurable.
