This new property be used as token to generate stable-ids instead
of the connection's UUID.
Later, this will be used by ipv6.addr-gen-mode=stable-privacy,
ethernet.cloned-mac-address=stable, and wifi.cloned-mac-address=stable
setting. Those generate stable addresses based on the connection's
UUID, but allow to use the stable-id instead.
This allows multiple connections to generate the same addresses
-- on the same machine, because in the above cases a machine
dependant key is also hashed.
This would fix for example:
nmcli e <TAB>
(e interpreted as --escape, would allow autocompletion to work... but
when the command is executed an error is reported)
Moreover, we will now have:
nmcli c <TAB>
autocompletion work correctly, i.e., c is correctly interpreted as
"connection" instead of "--colors"
When NM looks for vpn plugins, it would expect the full service name
otherwise it will not be able to retrieve the correct plugin.
Fixes VPN configurations generated with "nmcli connection add".
Re-enable the check on ambiguos properties but this time manage perfect
matches (i.e., the full property name has been typed) that are prefix
of other properties.
Test case:
nmcli --complete-args connection add type wifi wifi.
Here "wifi" is a property alias that is also prefix of the property
alias "wifi-sec".
When parsing arguments of "connection add" we first read the available
property-value pairs and then check if the --ask option was passed in
order to aid in the fill process of a new connection.
Anyway, if there are no property-value tuples at all, we don't even
check the --ask option, returning with error.
Fix this just checking if any arg is there (argc) before invoking
read_connection_properties().
If we found that setting name prefix is in fact unambiguous and return
the completion string for that setting we were freeing the string upon
the return. That looks like a typo.
Fixes "nmcli --complete-args add type wifi wifi."
^^^^ not ambiguous
It allows us to clean up the nmcli "c add" section considerably.
We list the old-fashioned aliases in a separate section that applies to both
"nmcli c add" and "nmcli c modify".
The section is now nicely cross-linked with nm-settings in HTML
rendering.
This is a huge refactoring in attempt to 1.) reduce the horrible redundancy in
the connection addition path and 2.) reduce confusion between various sources
of property value (command line, properties, interactive mode).
* The conversions from the strings was done all over the place:
settings.c already does for all sensible properties.
The rest is removed.
* The validations are done randomly and redundantly:
server does some validation, and per-property client validations
useful for interactive mode are done in settings.c
The rest is removed.
* The information about defaults and required options was redundantly
scattered in per-type completion functions and interactive mode
questionnaries. This is now driven by the option_info[] table.
In general, we do our best to just map the command line options to
properties and allow mixing them. For the rest there's the
check_and_set() callbacks (basically to keep compatibility with previous
nmcli versions). This this is now all possible:
$ nmcli c add type ethernet ifname '*'
This always worked
$ nmcli c add type bond-slave save no -- connection.autoconnect no
The "save" and "--" still work
$ nmcli c add connection.type ethernet ifname eth0
Properties can now be used
$ nmcli c add type ethernet ip4 1.2.3.4 mac 80:86:66:77:88:99 con-name whatever
There's no implementation mandated order of the properties (the type
still must be known to determine which properties make sense)
$ nmcli --ask c add type ethernet ip4 1.2.3.4 mac 80:86:66:77:88:99 con-name whatever
The interactive mode asks only for properties that weren't specified
on command line
Complete the property as we parse the list of properties. This makes it
possible to actually complete an unfinished property. E.g:
$ nmcli --complete c modify enp0s25 +ipv6.addr
+ipv6.addresses +ipv6.addr-gen-mode
Make property autocompletion take a prefix and modifier flags.
This will make it easier to complete an unfinished property name
(possibly accompanied by a modifier) without shell trickery.
nmcli bash autocompletion leveraged on "nmcli connection edit", "print"
to retrieve the specific properties of a connection. Anyway, the
interactive editor is smart and just prints the used components, so in a
connection where 802.1x is not enabled we had no autocompletion.
Solved adding an "hidden" command "nmcli --complete connection modify"
as suggested in bgo #724860 in order to retrieve ALL the available
properties for use in autocompletion.
Here patch from L.Rintel has been merged to make che --complete option
global to nmcli (first version was local to "connection modify").

* no need to check HELP_ONLY_AS_FIRST var as when --help option is passed
_nmcli_compl_OPTIONS will return 0, falling in the general case that
will trigger end of autocompletion
* clanup local var declaration in _nmcli func:
- remove dupliated OPTIONS_MANDATORY declaration
- init HELP_ONLY_AS_FIRST on declaration
- order vars for common prefix
nm_vpn_get_secret_names() has only one caller, which passes
nm_setting_vpn_get_service_type() as @vpn_type argument. That
argument is not a short-name or abbreviation, it must be the
full service-type.
For our well-known, hard-coded list of service-types, all must
start with the same prefix.
At various places, nmcli requires to specify a VPN type by name, for example
$ nmcli connection add type vpn ifname '*' vpn-type $VPN_TYPE
This $VPN_TYPE used to be a hard-coded list of known VPN plugin names.
But actually, it should be a VPN service-type. A service-type used to be
the D-Bus name of the VPN plugin. Now, with multiple VPN support that
is no longer the case, but it still has the form of a D-Bus bus name.
Alternativley, it could be an alias, which is just a way for plugins
to support multiple service-types.
Fix that, to support fully qualified service-types in the form
of D-Bus bus names. Also, support lookup by name, in which case
the present plugin-info instances are searched.
Finally, support a list of hard-code short-names.
All the logic how to translate a short-name to a fully qualified
service-type is now inside libnm, so that various user agree on
those names and don't have to hard-code them each.
g_qsort_with_data() passes the pointers to the compared items to the
compare function, that is not the "const char *" pointers itself.
