For some device types it's not going to be sufficient to tell whether
they carry "IP".
In particular, there's no way to carry legacy IP over the tiny MTU
datagrams of IEEE 802.15.4 WPAN links while an IPv6 transport exist
in form of 6LoWPAN.
Devices of different link types can actually have the same MAC address.
We'll want to use this to find a device of a particular type by its
hardware address.
With --color=auto, coloring is enabled based on the .enable/.disable
termcolors files.
Likewise, when we enable coloring, we parse the color palette from the
.schem termcolors files.
The termcolors files are searched by finding the best match depending
on the terminal and application name. Note, that if we find a matching
file like "nmcli@xterm.enable" we still allow loading the palette from
a less specific file like "nmcli.schem" and vice versa. That was already
done before.
Previously, the search was done by calling several layers of functions, and having
in/out arguments "color_option" and "p_palette_buffer". in/out paramters
here seems confusing to me, as they are state that gets modified and carried
along.
Instead, rework the functions to clearly separate between input
and output arguments.
Also, in the auto-case, check_colors() now first determines whether
coloring is enabled, before even starting loading the palette.
This avoids loading the palette until we are sure that we need it.
The NmCli variables is essentially a global variable of *everything*.
The set_color() function and its helpers only need a particular
part of it. Instead, of passing the entire global state to them,
only pass what they need.
It makes it clearer which parts are actually relevant. Turns out,
it only actually touches a resonable small part of the global state.
They are known to be racy and occasionally break. Especially in
cases where the system's CPU is busy, like during parallel
`make check -j`.
It's likely a bug in libnm-glib. libnm-glib is deprecated, and the
library didn't significantly change now for several releases.
Let's not invest effort into finding bugs in the deprecated library,
bugs that are known to exist. Also, at this point, larger rework
of libnm-glib is not going to happen anymore.
Retry the test up to 5 times, trying to workaround the test failures.
'num_grat_arp' and 'num_unsol_na' are actually the same attribute on
kernel side, so if only 'num_grat_arp' is set in configuration, we
first write its value and then overwrite it with the 'num_unsol_na'
default value (1). Instead, just write one of the two option.

A configuration with duplicate tc qdiscs and tfilters is not valid;
reject it in verify(). Note that nm_setting_tc_config_add_qdisc() and
nm_setting_tc_config_add_tfilter() can't add duplicate entries and so
the only way to achieve an invalid configuration is setting the
properties directly.

Internally, the device migth have negative or zero ifindex.
When calling nm_manager_get_device_by_ifindex(), the caller
wants to find a device with a valid ifindex, hence filter
out non-positive values.
<error> level is for something really bad happening. When another party
(iwd in this case) sends a D-Bus request that we cannot meaningfully handle,
that is hardly reason to warn about. <debug> level is enough in this case.
Also, give all messages a common prefix "agent-request" so that we have
something to grep for.
nm_utils_random_bytes() will always try its best to give some
random numbers. A failure only means, that the kernel interfaces
get_random() or /dev/urandom failed to provide good randomness. We
don't really need good random numbers here, so no need to handle
a failure.
priv->system_secrets may be updated by e.g.
nm_settings_connection_new_secrets and nm_settings_connection_update,
but if the plugin creates the object with g_object_new, then adds some
settings but never adds any secrets there's no reason to call either of
those two methods. A call to nm_settings_connection_get_secrets should
still be able to request new secrets (and may then update
priv->system_secrets as a result).
If the hints parameter to the agent request wasn't empty, ask
specifically for the 802-1x keys listed in the hints and skip the
guessing. I didn't add human readable names for all of the 802-1x
settings, it could be useful to do for at least the three 802-1x
properties that add_8021x_secrets already knows about because
those may have translations.
Allow the IWD backend to use secrets provided in the connection settings
on initial connection attempt, only require new secrets on subsequent
connections when IWD asks for them -- it only asks if fresh secrets are
required.
The IWD DBus interface currently
(https://git.kernel.org/pub/scm/network/wireless/iwd.git/tree/doc/agent-api.txt?id=38952813dddd776f66d2ed5e88eca9a892964c06)
knows about 3 secret types related to 802.1x authentication in addition
to the PSK secret request. Add support for the new methods and the new
secret types in NM's implementation of the IWD secret agent. Note that
the secret types are mapped to NMSetting8021x property keys and they are
then sent to the NM Secret Agent in the hints parameter to GetSecrets,
this will need support in the NM clients as the exact usage of the
hints parameter is specified a little ambiguously, but this seems to be
one of the permitted usages.
Rework the IWD agent interface info initialization to use NM convenience
macros.
To improve the code logic and reduce space for bugs, don't save the
dbus invocation object as priv->secrets_request, instead move it to
the nm_act_request_get_secrets()'s user_data as we only need the
invocation object for exactly the life time of the request. See
https://github.com/NetworkManager/NetworkManager/pull/139 for
discussion.
