Do not proceed resolving the setting name if it does not pass
check_valid_name().
In case the user selects a setting/property with "goto" command, and
then attempts to tab-complete a setting/property pair, the original sett
and prop strings are overriden without freeing:
nmcli > goto 802-1x.pac-file
nmcli 802-1x.pac-file> set 802-1.lal<TAB>
Fixes: 79bc271685 ('cli: TAB-completion for enum-style property values (rh #1034126)')
Not all setting names are valid values for the value of the connection's "type".
However, if a shortened value is introduced, all setting names are
considered, like in:
Error: bad connection type: 'eth' is ambiguous: ethernet, ethtool
Note that ethtool is not a valid value for "type".
Fix it by considering only "base" settings names.
Add a new "generic.device-handler" property that specifies the name of
a dispatcher script to be invoked to add and delete the interface for
this connection.

(cherry picked from commit 416d596b31)
This patch add support to HSR/PRP interface. Please notice that PRP
driver is represented as HSR too. They are different drivers but on
kernel they are integrated together.
HSR/PRP is a network protocol standard for Ethernet that provides
seamless failover against failure of any network component. It intends
to be transparent to the application. These protocols are useful for
applications that request high availability and short switchover time
e.g electrical substation or high power inverters.

CMP() is a confusing pattern. Sure enough, the sort order was wrong, for
example, `nmcli connection` would show
$ nmcli -f STATE,UUID,DEVICE c
STATE UUID DEVICE
activating 3098c902-c59c-45f4-9e5a-e4cdb79cfe1b nm-bond
activated e4fc23ac-54ab-4b1a-932a-ebed12c96d9b eth1
("activating" shown before "activated").
With `nmcli device`, we sort with compare_devices(). This first sorts by
device state (with "connected" being sorted first). Only when the device
state is equal, we fallback to nmc_active_connection_cmp(). So with
`nmcli device` we usually get "connected" devices first, and we don't
really notice that there is a problem with nmc_active_connection_cmp().
On the other hand, `nmcli connection` likes to sort first via
nmc_active_connection_cmp(), which gets it wrong. Profiles in
"activating" state are sorted first. That's inconsistent with `nmcli
device`, but it's also not what is intended.
Fix that.
Note the change in the test output. Both eth1 and eth0 are connected to
to the same profile, but one "eth0" the active-connection's state is
DEACTIVATING, while on "eth1" it's ACTIVATED (but both device's states
are "CONNECTED"). That's why "eth1" is now sorted first (as desired).
Fixes: a1b25a47b0 ('cli: rework printing of `nmcli connection` for multiple active connections')
This flag is a setting that changes the behaviour of nmcli, it's not
only the current state of the program, so it makes more sense to put it
in NmcConfig than in NmCli.
Furthermore, it's needed to fix a bug in next commit, too.
- drop annotations from "@error" which has defaults.
- ensure all annotations are on the same line. That's useful
when searching for an annotation, to find the line that specifies
the argument name.
- convert a few plain docs into gtkdoc annotations.
The main purpose is to simplify printf debugging and manual testing. We
can now trivially patch the code so that all output from nmcli gets
(additionally) written to a file. That is useful when debugging a unit
test in "test-client.py". Thereby we can duplicate all messages via
nm_utils_print(), which is in sync with the debug messages from libnm
and which honors LIBNM_CLIENT_DEBUG_FILE.
(cherry picked from commit b32e4c941a)
nmc_print() will be used for something else. Rename. Also,
nmc_print_table() is the better name anyway because the function does a
lot of formatting and not simple printf().
(cherry picked from commit 4b2ded7a4a)
It seems uncommon that a command line tool warns about duplicate
paramters. Usually, the latter just overwrites the former. That is also
useful so that you can have for example an alias that sets a default
type
nmcli_import="nmcli connection import type keyfile"
but still call it like
nmcli_import file $FILE type openvpn
This is a change in behavior. Not only stop we printing a warning, we
will now prefer the latter argument. Previously, the first was honored.
This change in behavior is a problem, but such uses were warned against
in the past, and hopefully nobody did this or relied on this.
These variants provide additional nm_assert() checks, and are thus
preferable.
Note that we cannot just blindly replace &g_array_index() with
&nm_g_array_index(), because the latter would not allow getting a
pointer at index [arr->len]. That might be a valid (though uncommon)
usecase. The correct replacement of &g_array_index() is thus
nm_g_array_index_p().
I checked the code manually and replaced uses of nm_g_array_index_p()
with &nm_g_array_index(), if that was a safe thing to do. The latter
seems preferable, because it is familar to &g_array_index().
We almost always do the wrong thing in interactive add:
The software devices generally require an interactive name, but we don't
insist of asking for them; treating them as optional:
$ nmcli -a c add type dummy
There is 1 optional setting for General settings.
Do you want to provide it? (yes/no) [yes]
For some interface types (bridges, bonds, ...) we make up a name, presumably
for historical reasons. But we don't give the user an option to modify
them:
$ nmcli -a c add type bridge
<not asking for interface name at all>
There are 9 optional settings for Bridge device.
Do you want to provide them? (yes/no) [yes]
This fixes the above use cases -- still set the default, but be sure to
ask:
$ nmcli -a c add type dummy
Interface name:
$ nmcli -a c add type bridge
Interface name [nm-bridge1]:
Beautiful.
Do the same bookkeeping as would happen upon setting the "type" option
when the connection has a connection.type set upon its addition.
Otherwise the --ask mode is sad:
$ nmcli --ask c add connection.type team
** nm:ERROR:src/nmcli/connections.c:5648:connection_get_base_meta_setting_type: assertion failed: (base_setting)
Bail out! nm:ERROR:src/nmcli/connections.c:5648:connection_get_base_meta_setting_type: assertion failed: (base_setting)
Aborted (core dumped)
After the connection's type is set, some bookkeeping is necessary for
the interactive (--ask) mode: appropriate setting need to be added and
options enabled.
Currently it happens in an option setter; which runs when the "type"
options is present on the command line, or the value is set in a
response to interactive mode:
$ nmcli --ask c add type team
$ nmcli --ask c add
Connection type: team
But not when the property is set directly:
$ nmcli --ask c add connection.type team
** nm:ERROR:src/nmcli/connections.c:5648:connection_get_base_meta_setting_type: assertion failed: (base_setting)
Bail out! nm:ERROR:src/nmcli/connections.c:5648:connection_get_base_meta_setting_type: assertion failed: (base_setting)
Aborted (core dumped)
This doesn't fix the issue -- a followup commit (hopefully) will.
For new connections, this ensures the value in square brackets on
interactive add are always correct.
Apart from that, this allows us to initialize some non-default values
before asking (such as making up an interface name for some software
devices), and inform the user about what we picked:
Interface name [nm-bridge]:
This is slightly annoying:
$ nmcli -a c add type ethernet
There is 1 optional setting for General settings.
No point in asking if there's just one option. Just ask right away:
$ nmcli -a c add type ethernet
Interface name:
The interactive add is not too enthusiastic about not providing a value
in a list.
That is before on getting an empty line in ask_option() we take a
shortcut instead of dispatching to set_option(). That way we skip
setting the PROPERTY_INF_FLAG_DISABLED flag, causing the option to
be included in questionnaire_one_optional()'s info list.
There's no reason to avoid calling set_option() if we don't get a value;
set_option() handles NULL value just fine.
$ nmcli -a c add
Connection type: dummy
There is 1 optional setting for General settings.
Do you want to provide it? (yes/no) [yes]
Interface name [*]: lala
There are 2 optional settings for IPv4 protocol.
Do you want to provide them? (yes/no) [yes]

This adds a global "--offline" option and allows its use with "add" and
"modify" commands. The "add" looks like this:
$ nmcli --offline conn add type ethernet ens3 ipv4.dns 192.168.1.1 \
>output.nmconnection
The "modify" is essentially implementing what's been suggested by
Beniamino in bugzilla ticked (referred to below):
$ nmcli --offline connection modify ens3 ipv4.dns 192.168.1.1 \
<input.nmconnection >output.nmconnection
Other commands don't support the argument at the moment:
$ nmcli --offline c up ens3
Error: 'up' command doesn't support --offline mode.
