> connectivity: use separate IPv4 and IPv6 connection checks

        case NM_DEVICE_STATE_ACTIVATED:
                _LOGI (LOGD_DEVICE, "Activation: successful, device activated.");
+
+               update_connectivity_state (self, AF_INET, NM_CONNECTIVITY_UNKNOWN);
+               update_connectivity_state (self, AF_INET6, NM_CONNECTIVITY_UNKNOWN);

I think this will set IPv4 and IPv6 connectivity immediately to FULL
before performing the connectivity check.


In the journal I see:

 connectivity: (ens3) sending request to 'http://fedoraproject.org/static/hotspot.txt'
 connectivity: (ens3) sending request to 'http://fedoraproject.org/static/hotspot.txt'
 ...
 connectivity: (ens3) check successful.
 connectivity: (ens3) check successful.

Maybe add a @family member to ConCheckCbData and print also the family
in log messages?

> introspection/device: export Ip[46]Connectivity properties

+        The result of the last connectivity check using IPv4 no this device.
+        See "Connectivity" property of the "/org/freedesktop/NetworkManager" object
+        for more details..

s/no/on/
double ending period.
The same for IPv6.

> dispatcher: indicate the connectivity state per device and AF

+       if (connectivity_state4 && strcmp(connectivity_state4, "UNKNOWN"))
+               items = g_slist_prepend (items, g_strdup_printf ("IP4_CONNECTIVITY_STATE=%s", connectivity_state));

Missing space after strcmp.
s/connectivity_state/connectivity_state4/

+       if (connectivity_state6 && strcmp(connectivity_state6, "UNKNOWN"))
+               items = g_slist_prepend (items, g_strdup_printf ("IP6_CONNECTIVITY_STATE=%s", connectivity_state));

Ditto.

bugzilla.gnome.org is being shut down in favor of a GitLab instance. 
We are closing all old bug reports and feature requests in GNOME Bugzilla which have not seen updates for a long time.

If you still use NetworkManager and if you still see this bug / want this feature in a recent and supported version of NetworkManager, then please feel free to report it at https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/

Thank you for creating this report and we are sorry it could not be implemented (workforce and time is unfortunately limited).
