The unmanaged flags PLATFORM_INIT indicates whether UDEV is done initializing the device. We should not handle IP config changes before that pointer. This avoids codepaths that require the permanent MAC address of the device. We should not freeze the permanent MAC address before UDEV initialized the device, for two reasons: - getting the permanent MAC address using ethtool is racy as UDEV might still rename the interface. - freezing a fake permanent MAC address should only happen after UDEV is done configuring the MAC address of software devices. #0 0x000055555568bc7a in nm_device_update_permanent_hw_address (self=self@entry=0x555555f0fb70 [NMDeviceVeth], force_freeze=force_freeze@entry=1) at src/devices/nm-device.c:11817 #1 0x000055555568c443 in nm_device_get_permanent_hw_address_full (self=self@entry=0x555555f0fb70 [NMDeviceVeth], force_freeze=force_freeze@entry=1, out_is_fake=out_is_fake@entry=0x0) at src/devices/nm-device.c:12227 #2 0x000055555568cb06 in nm_device_get_permanent_hw_address (self=self@entry=0x555555f0fb70 [NMDeviceVeth]) at src/devices/nm-device.c:12237 #3 0x000055555568cb50 in spec_match_list (self=0x555555f0fb70 [NMDeviceVeth], specs=0x555555a5c000 = {...}) at src/devices/nm-device.c:12294 #4 0x00005555556a4ee6 in spec_match_list (device=0x555555f0fb70 [NMDeviceVeth], specs=0x555555a5c000 = {...}) at src/devices/nm-device-ethernet.c:1461 #5 0x00005555556978db in nm_device_spec_match_list (self=self@entry=0x555555f0fb70 [NMDeviceVeth], specs=0x555555a5c000 = {...}) at src/devices/nm-device.c:12277 #6 0x000055555558e187 in _match_section_infos_lookup (match_section_infos=0x555555a5d500, keyfile=0x555555a46f80, property=property@entry=0x555555793123 "ipv4.route-metric", device=device@entry=0x555555f0fb70 [NMDeviceVeth], out_value=out_value@entry=0x7fffffffe018) at src/nm-config-data.c:1169 #7 0x00005555555922ca in nm_config_data_get_connection_default (self=0x555555a548c0 [NMConfigData], property=property@entry=0x555555793123 "ipv4.route-metric", device=device@entry=0x555555f0fb70 [NMDeviceVeth]) at src/nm-config-data.c:1234 #8 0x00005555556790cd in _get_ipx_route_metric (self=self@entry=0x555555f0fb70 [NMDeviceVeth], is_v4=is_v4@entry=1) at src/devices/nm-device.c:1142 #9 0x000055555567912e in nm_device_get_ip4_route_metric (self=self@entry=0x555555f0fb70 [NMDeviceVeth]) at src/devices/nm-device.c:1161 #10 0x000055555567da6c in ip4_config_merge_and_apply (self=self@entry=0x555555f0fb70 [NMDeviceVeth], config=config@entry=0x0, commit=commit@entry=0, out_reason=out_reason@entry=0x0) at src/devices/nm-device.c:4787 #11 0x000055555567e0fb in update_ip4_config (self=self@entry=0x555555f0fb70 [NMDeviceVeth], initial=initial@entry=0) at src/devices/nm-device.c:9532 #12 0x0000555555693acd in queued_ip4_config_change (user_data=0x555555f0fb70) at src/devices/nm-device.c:9651 #13 0x00007ffff4c966ba in g_main_context_dispatch (context=0x555555a46af0) at gmain.c:3154 #14 0x00007ffff4c966ba in g_main_context_dispatch (context=context@entry=0x555555a46af0) at gmain.c:3769 #15 0x00007ffff4c96a70 in g_main_context_iterate (context=0x555555a46af0, block=block@entry=1, dispatch=dispatch@entry=1, self=<optimized out>) at gmain.c:3840 #16 0x00007ffff4c96d92 in g_main_loop_run (loop=0x555555a47400) at gmain.c:4034 #17 0x000055555558372a in main (argc=<optimized out>, argv=<optimized out>) at src/main.c:411

When a VPN connection can't be activated we have to unexport and dispose it. Commit f2182fb ("core: don't emit double PropertiesChanged signal for new active connections") removed the call to nm_exported_object_unexport() in case of failure because the active connection already gets unreferenced on failure. However, an exported object can't be disposed until it's explicitly unexported because GDBus code keeps a reference to it. The result was that the active connection was kept alive and exported, but without explicit references to it.

Fixes: f2182fb https://bugzilla.redhat.com/show_bug.cgi?id=1440077

When a VPN connection can't be activated we have to unexport and dispose it. Commit f2182fb ("core: don't emit double PropertiesChanged signal for new active connections") removed the call to nm_exported_object_unexport() in case of failure because the active connection already gets unreferenced on failure. However, an exported object can't be disposed until it's explicitly unexported because GDBus code keeps a reference to it. The result was that the active connection was kept alive and exported, but without explicit references to it. As soon as the connection was unexported, it was also automatically disposed, causing issues like: (src/nm-exported-object.c:1025):dispose: code should not be reached #0 _g_log_abort () at /lib64/libglib-2.0.so.0 #1 g_logv () at /lib64/libglib-2.0.so.0 #2 g_log () at /lib64/libglib-2.0.so.0 #3 g_warn_message () at /lib64/libglib-2.0.so.0 #4 dispose (object=0xaaf110) at src/nm-exported-object.c:1025 #5 dispose (object=0xaaf110) at src/nm-active-connection.c:1246 #6 dispose (object=0xaaf110) at src/vpn/nm-vpn-connection.c:2642 #7 g_object_unref () at /lib64/libgobject-2.0.so.0 #8 registration_data_free () at /lib64/libgio-2.0.so.0 #9 g_hash_table_remove_internal () at /lib64/libglib-2.0.so.0 #10 g_dbus_object_manager_server_unexport_unlocked () at /lib64/libgio-2.0.so.0 #11 g_dbus_object_manager_server_unexport () at /lib64/libgio-2.0.so.0 #12 nm_bus_manager_unregister_object (self=0x9069e0, object=object@entry=0xaaf110) at src/nm-bus-manager.c:858 #13 nm_exported_object_unexport (self=0xaaf110) at src/nm-exported-object.c:714 #14 _settings_connection_removed (connection=<optimized out>, user_data=0xaaf110) at src/nm-active-connection.c:184 #15 g_closure_invoke () at /lib64/libgobject-2.0.so.0 #16 signal_emit_unlocked_R () at /lib64/libgobject-2.0.so.0 #17 g_signal_emit_valist () at /lib64/libgobject-2.0.so.0 #18 g_signal_emit_by_name () at /lib64/libgobject-2.0.so.0 #19 nm_settings_connection_signal_remove (self=self@entry=0x9e4a80, allow_reuse=allow_reuse@entry=0) at src/settings/nm-settings-connection.c:2085 #20 do_delete (self=0x9e4a80, callback=0x58106a <con_delete_cb>, user_data=0xa84fa0) at src/settings/nm-settings-connection.c:768 #21 do_delete (connection=0x9e4a80, callback=0x58106a <con_delete_cb>, user_data=0xa84fa0) at src/settings/plugins/keyfile/nms-keyfile-connection.c:127 #22 nm_settings_connection_delete (self=self@entry=0x9e4a80, callback=callback@entry=0x58106a <con_delete_cb>, user_data=0xa84fa0) at src/settings/nm-settings-connection.c:694 #23 delete_auth_cb (self=self@entry=0x9e4a80, context=context@entry=0x7fffd80131e0, subject=0x91fb40, error=<optimized out>, data=data@entry=0x0) at src/settings/nm-settings-connection.c:1879 #24 pk_auth_cb (chain=0x7fffd00024a0, chain_error=<optimized out>, context=0x7fffd80131e0, user_data=<optimized out>) at src/settings/nm-settings-connection.c:1351 #25 auth_chain_finish (user_data=0x7fffd00024a0) at src/nm-auth-utils.c:92 #26 g_idle_dispatch () at /lib64/libglib-2.0.so.0 Restore the unexport upon failure to fix this.

As workaround, ignore the ndisc signal, if we currently don't have an ifindex. Also, recreate the NMIP6Config instances, if the ifindex doesn't match (or we don't have one). This workaround is probably good enough for the stable branch, as the code on main (1.35+) was heavily reworked and the fix does not apply there. https://bugzilla.redhat.com/show_bug.cgi?id=2013266#c1

The ACD state handling is unfortunately very complicated. That is, because we obviously need to track state about how ACD is going (acd_data, and in particular NML3AcdAddrState). Then there are various things that can happen, which are the AcdStateChangeMode enums. All these state-changes are then in one function: _l3_acd_data_state_change(), which is therefore complicated (I don't think that it would become simpler by spreading this code out to different functions, on the contrary). Anyway. So, what happens when we need to reset the n-acd instance? For example, because the MAC address of the link changed or some error. I guess, we need to restart probing. Previously, I think this was not handled properly. We already tried to fix this several times, the last was commit b331606 ('l3cfg: on n-acd instance-reset clear also ready ACD state'). There is still an issue ([1]). The bug [1] is, that we are in state NM_L3_ACD_ADDR_STATE_READY, during ACD_STATE_CHANGE_MODE_TIMEOUT event.

…oved_track() We can get a platform signal for any number of reasons. In particular, we can get a signal that the object exists in platform, while the object is tracked as zombie. "Zombies" are objects that we once actively configured, but now no longer and thus need to remove them. We remember that we need to delete the object in kernel. The assertion was wrong.
