In constructed(), NMDevice starts watching the D-Bus name owner or
monitoring the unix socket, and so it is always aware if teamd is
running. When it is, NMDevice connects to it and initializes
priv->tdc.
It is not useful to try to connect to teamd in update_connection()
because warnings will be generated by NM and by libteam if teamd is
not running. As explained above the connection is always initialized
when teamd is available, and so we can just check priv->tdc.

This ABI was backported all the way to 1.42.8 and 1.40.20 and to rhel-8.9.
Move the ABI to a separate symbol version, which we have in all those
versions.
With the unit test framework, we define special methods, like setUp()
and test_*(). This is documented, but not obvious.
Previously, TestNmClient was the base class for our tests classes, and
it provided some functionality (and state). It was utterly confusing how
pieces fit together.
Instead, move the state to a new class NMTestContext(). That contains
most of the code from TestNmClient. Drop TestNmClient and let the test
classes directly descend from unittest.TestCase.
The difference is, when you now look at a certain test (test_001()), you
can easier understand which code runs when. First, the test class has a
setUp() method which runs, but that method is now trivial without extra
context. Second, there is the @nm_test attribute that wraps the
function. But that's it. It's all at one place, and we delegate instead
of inherit.
Currently if the IPv6 link-local address is removed after it passed
DAD, NetworkManager tries to generate a new link-local address. If
this fails, which is always the case for EUI64, ipv6ll is considered
as failed and the connection can go down (depending on may-fail).
This is particularly bad for virtual interfaces because if somebody
removes the link-local address, the activation can fail and destroy
the interface, breaking all services that require it. Also, it's a
change in behavior introduced in 1.36.0.
It seems that a better approach here is to re-add the address that was
removed externally.

When managing the interface after wake/reenable, the reason determines
whether the device will be sys-iface-state=managed or external.
Commit 5a9a7623c5 ('core: set STATE_REASON_CONNECTION_ASSUMED when
waking up') changed the reason from 'now-managed' to
'connection-assumed'; the effect was that devices that were fully
managed before sleeping become external after a wake up. For example:
$ nmcli connection add type ethernet ifname enp1s0
Connection 'ethernet-enp1s0' (47fcd81e-bf00-4c02-b25b-354894f5657e) successfully added.
$ nmcli device | grep enp1s0
enp1s0 ethernet connected ethernet-enp1s0
$ nmcli networking off
$ nmcli device | grep enp1s0
enp1s0 ethernet unmanaged --
$ nmcli networking on
$ nmcli device | grep enp1s0
enp1s0 ethernet unavailable --
Set the correct reason during wake up so that the previous state is
restored.

- use G_N_ELEMENTS() macro instead of having separate defines. The separate
defines mean that when we check g_return_val_if_fail(oc_argc <= OC_ARGS_MAX, FALSE)
that we must double check that OC_ARGS_MAX is really the size of the array
that we want to check.
- replace g_return_val_if_fail() with nm_assert(). In this case, it should be
very clear by review that the buffer is indeed large enough and the assertion
holds. Use nm_assert().
- use unsigned integer for the loop variables. While int theoretically
might exploit undefined behavior of signed overflow, we should instead
use unsigned at places where it's appropriate (for example, those
variables are compared against G_N_ELEMENTS() which gives a size_t type.
- declare auto variables on separate lines.
- make the global variable oc_property_args static and const. The const
means the linker will put it into read-only memory, so we would get
a crash on accidental modification.
Don't rely on resources provided by mock metadata server by default,
create the from within the test instead.
This allows for more flexibility, but the locality of the test fixture
relative to the tests makes the test more legible.
This reworks the cloud metadata mock server in a significant way.
Most importantly this makes it possible for the client to add and
modify the resources for later retrieval using the PUT method.
This allows the test to create the fixture for itself.
The default set of resources is still provided, so that the too remains
useful as a development aid. If that is not desirable, the --empty
parameter might be passed to cause the server to start with no
resources.
When a pexpect check fails, we want to see the full content of the
buffer, so we can better see where it went wrong. Increase the context
that is printed in the error message.
The routes in iproutes were leaked (and ownership stolen
in _nmc_mangle_connection(), leaving dangling pointers).
Fix that by using a GPtrArray instead.
With old versions of openconnect we need to extract the port# from the
initial URL and then append it to the hostname we eventually get back.
Using strrchr(gw, ':') isn't going to work right with IPv6 literals,
ad we should also be dropping any path element.
So switch to using an int for the port instead of a string, and import a
cut-down variant of openconnect's internal_parse_url() which does
*largely* the same thing with strrchr() but is saved by using the 'end'
value returned from strtol() and insisting that the port is the very
end of the host part of the URL.
Rather than letting openconnect run, and whine that there's no gateway,
and making the user scroll up past the openconnect usage information,
give them an explicit error.
While we're at it, kill the separate openconnect_authenticate() function
since it barely does anything any more and it wants visibility to both
's_vpn' and 'success' variables in the caller.
Pull a bunch of stuff into nm_vpn_openconnect_authenticate_helper() that
both callers were doing for themselves, and make its API a bit simpler.
It's given the NMSettingVpn and the GPtrArray of secrets, and it simply
succeeds or fails.
Ideally, we wouldn't have this hard-coded in NetworkManager itself; we
would invoke a tool to do it for us, like the GUI auth-dialog, which
can live in the NetworkManager-openconnect repository and be kept up
to date as new options are added.
To start with though, let's bring it into sync. We don't add new options
that often, and this will cover the majority of use cases.
Since OpenConnect 8.20, 'openconnect --authenticate' will return the
full gateway URL, including the hostname and the path. This allows
servers behind SNI-based proxies to work. To ensure we end up at the
same IP address even behind round-robin DNS, there is a separate
--resolve argument.
Update nmcli/nmtui to use this, as NetworkManager-openconnect does.
Shift some of the logic into the nm_vpn_openconnect_authenticate_helper()
function instead of duplicating it in the callers.
Also, pass the correct protocol in rather than only supporting Cisco
AnyConnect.
