We listen to all RTM_GETLINK messages to get updates on interfaces statuses. Unfortunately wireless code in the kernel sends those messages with wireless information included and all other information excluded. When we receive such message we wipe out our valid cached entry with new object that is almost empty because netlink message didn't contain any information. Solution to this is to check that incoming message contains MTU field: this field is always set for complete messages about interfaces and is not set by wireless code.

At other places, we take the partial information that is in the netlink message and complete it with the data we have in cache. See "completed_from_cache": NetworkManager/src/platform/nm-linux-platform.c Line 1649 in e70dfb4 Are you confident that these incomplete messages are entirely useless for NM and we can safely ignore them altogether? |

I'm relatively confident that those particular messages do not contain any information useful for this specific function: they all seem to be results of wifi scans. I did not realize that there is already code that merges from cache. I can see if I can rewrite this patch to merge other fields too - if that's what you would prefer. |

No, since you seem sufficiently confident, that seems not necessary. Patch lgtm. |

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 NetworkManager#1 g_logv () at /lib64/libglib-2.0.so.0 NetworkManager#2 g_log () at /lib64/libglib-2.0.so.0 NetworkManager#3 g_warn_message () at /lib64/libglib-2.0.so.0 NetworkManager#4 dispose (object=0xaaf110) at src/nm-exported-object.c:1025 NetworkManager#5 dispose (object=0xaaf110) at src/nm-active-connection.c:1246 NetworkManager#6 dispose (object=0xaaf110) at src/vpn/nm-vpn-connection.c:2642 NetworkManager#7 g_object_unref () at /lib64/libgobject-2.0.so.0 NetworkManager#8 registration_data_free () at /lib64/libgio-2.0.so.0 NetworkManager#9 g_hash_table_remove_internal () at /lib64/libglib-2.0.so.0 NetworkManager#10 g_dbus_object_manager_server_unexport_unlocked () at /lib64/libgio-2.0.so.0 NetworkManager#11 g_dbus_object_manager_server_unexport () at /lib64/libgio-2.0.so.0 NetworkManager#12 nm_bus_manager_unregister_object (self=0x9069e0, object=object@entry=0xaaf110) at src/nm-bus-manager.c:858 NetworkManager#13 nm_exported_object_unexport (self=0xaaf110) at src/nm-exported-object.c:714 NetworkManager#14 _settings_connection_removed (connection=<optimized out>, user_data=0xaaf110) at src/nm-active-connection.c:184 NetworkManager#15 g_closure_invoke () at /lib64/libgobject-2.0.so.0 NetworkManager#16 signal_emit_unlocked_R () at /lib64/libgobject-2.0.so.0 NetworkManager#17 g_signal_emit_valist () at /lib64/libgobject-2.0.so.0 NetworkManager#18 g_signal_emit_by_name () at /lib64/libgobject-2.0.so.0 NetworkManager#19 nm_settings_connection_signal_remove (self=self@entry=0x9e4a80, allow_reuse=allow_reuse@entry=0) at src/settings/nm-settings-connection.c:2085 NetworkManager#20 do_delete (self=0x9e4a80, callback=0x58106a <con_delete_cb>, user_data=0xa84fa0) at src/settings/nm-settings-connection.c:768 NetworkManager#21 do_delete (connection=0x9e4a80, callback=0x58106a <con_delete_cb>, user_data=0xa84fa0) at src/settings/plugins/keyfile/nms-keyfile-connection.c:127 NetworkManager#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 NetworkManager#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 NetworkManager#24 pk_auth_cb (chain=0x7fffd00024a0, chain_error=<optimized out>, context=0x7fffd80131e0, user_data=<optimized out>) at src/settings/nm-settings-connection.c:1351 NetworkManager#25 auth_chain_finish (user_data=0x7fffd00024a0) at src/nm-auth-utils.c:92 NetworkManager#26 g_idle_dispatch () at /lib64/libglib-2.0.so.0 Restore the unexport upon failure to fix this.

When adding a new Wi-Fi connection, nmtui crashes.
Usually, a verified Wi-Fi connection always has key_mgnt set.
However, the client doesn't have the luxury to assume that all
connections verify. Especially, while creating a new connection.

When NM quits it destroys all singletons including NMOvsdb, which invokes callbacks for every pending method call. In the shutdown, extra care must be taken to not access objects that are already in a inconsistent state; for example here, the callback changes the device state, and this causes an access to data that has already been cleared: #0 _g_log_abort (breakpoint=breakpoint@entry=1) at gmessages.c:554 #1 g_logv (log_domain=0x5635653b6817 "NetworkManager", log_level=G_LOG_LEVEL_CRITICAL, format=<optimized out>, args=args@entry=0x7fffb4b2c1e0) at gmessages.c:1362 #2 g_log (log_domain=log_domain@entry=0x5635653b6817 "NetworkManager", log_level=log_level@entry=G_LOG_LEVEL_CRITICAL, format=format@entry=0x7fbb3f58fa4a "%s: assertion '%s' failed") at gmessages.c:1403 #3 g_return_if_fail_warning (log_domain=log_domain@entry=0x5635653b6817 "NetworkManager", pretty_function=pretty_function@entry=0x5635653b6b00 <__func__.34463> "nm_device_factory_manager_find_factory_for_connection", expression=expression@entry=0x5635653b6719 "factories_by_setting") at gmessages.c:2702 #4 nm_device_factory_manager_find_factory_for_connection (connection=connection@entry=0x56356627e0e0) at src/devices/nm-device-factory.c:243 #5 nm_manager_get_connection_iface (self=0x563566241080 [NMManager], connection=connection@entry=0x56356627e0e0, out_parent=out_parent@entry=0x0, error=error@entry=0x0) at src/nm-manager.c:1458 #6 check_connection_compatible (self=<optimized out>, connection=0x56356627e0e0) at src/devices/nm-device.c:4679 #7 check_connection_compatible (device=0x56356647b1b0 [NMDeviceOvsInterface], connection=0x56356627e0e0) at src/devices/ovs/nm-device-ovs-interface.c:95 #8 _nm_device_check_connection_available (self=0x56356647b1b0 [NMDeviceOvsInterface], connection=0x56356627e0e0, flags=NM_DEVICE_CHECK_CON_AVAILABLE_NONE, specific_object=0x0) at src/devices/nm-device.c:12102 #9 nm_device_check_connection_available (self=self@entry=0x56356647b1b0 [NMDeviceOvsInterface], connection=0x56356627e0e0, flags=flags@entry=NM_DEVICE_CHECK_CON_AVAILABLE_NONE, specific_object=specific_object@entry=0x0) at src/devices/nm-device.c:12131 #10 nm_device_recheck_available_connections (self=self@entry=0x56356647b1b0 [NMDeviceOvsInterface]) at src/devices/nm-device.c:12238 #11 _set_state_full (self=self@entry=0x56356647b1b0 [NMDeviceOvsInterface], state=state@entry=NM_DEVICE_STATE_FAILED, reason=reason@entry=NM_DEVICE_STATE_REASON_OVSDB_FAILED, quitting=quitting@entry=0) at src/devices/nm-device.c:13065 #12 nm_device_state_changed (self=self@entry=0x56356647b1b0 [NMDeviceOvsInterface], state=state@entry=NM_DEVICE_STATE_FAILED, reason=reason@entry=NM_DEVICE_STATE_REASON_OVSDB_FAILED) at src/devices/nm-device.c:13328 #13 del_iface_cb (error=<optimized out>, user_data=0x56356647b1b0) at src/devices/ovs/nm-device-ovs-port.c:160 #14 _transact_cb (self=self@entry=0x5635662b9ba0 [NMOvsdb], result=result@entry=0x0, error=0x563566259a10, user_data=user_data@entry=0x5635662ff320) at src/devices/ovs/nm-ovsdb.c:1449 #15 ovsdb_disconnect (self=self@entry=0x5635662b9ba0 [NMOvsdb]) at src/devices/ovs/nm-ovsdb.c:1331 #16 dispose (object=0x5635662b9ba0 [NMOvsdb]) at src/devices/ovs/nm-ovsdb.c:1558 #17 g_object_unref (_object=0x5635662b9ba0) at gobject.c:3293 #18 _nm_singleton_instance_destroy () at src/nm-core-utils.c:138 #19 _dl_fini () at dl-fini.c:253 #20 __run_exit_handlers (status=status@entry=0, listp=0x7fbb3e1ad6c8 <__exit_funcs>, run_list_atexit=run_list_atexit@entry=true) at exit.c:77 #21 __GI_exit (status=status@entry=0) at exit.c:99 #22 main (argc=1, argv=0x7fffb4b2cc38) at src/main.c:468 Add a new error code to indicate to callbacks that we are quitting and no further action must be taken.

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.

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

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 https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/merge_requests/1058 (cherry picked from commit 94215cd)

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. We don't need to handle the case "in_platform"
and linked in "os_zombie_lst" specially.

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. We don't need to handle the case "in_platform"
and linked in "os_zombie_lst" specially.

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. We don't need to handle the case "in_platform"
and linked in "os_zombie_lst" specially.

When cloud-init job (metadata service crawler) starts, it sends the SIGTERM signal to nm-cloud-setup and force the nm-cloud-setup to restart, however, because the error is not initialized as NULL in `_init_start_cancelled_cb()` before it is set, nm-cloud-setup will hit a dumped core.

We listen to all RTM_GETLINK messages to get updates on interfaces statuses.
Unfortunately wireless code in the kernel sends those messages with wireless information included
and all other information excluded. When we receive such message we wipe out our valid cached entry
with new object that is almost empty because netlink message didn't contain any information.
Solution to this is to check that incoming message contains MTU field: this field is always
set for complete messages about interfaces and is not set by wireless code.
