+Subject: [PATCH] libteamdctl: validate the bus name before using it
+
+Using bus name without validating it will cause core dump generated,
+and it can be reproduced by:
+
+  # ip link add dummy0.1 type dummy
+  # teamdctl dummy0.1 state dump
+
+  This is normally a bug in some application using the D-Bus library.
+
+    D-Bus not built with -rdynamic so unable to print a backtrace
+  Aborted (core dumped)
+
+Doing this many times can even create too many core files, customers
+may complain about it.
+
+This is triggered when calling cli_method_call("ConfigDump") in
+cli_init(), so fix it by returning err in cli->init/cli_dbus_init()
+if the bus name fails to validate.
+
+Note this is safe, as with dbus, we can't use invalid dbus name to
+create the team dev either.
+
+Fixes: d8163e34c25c ("libteamdctl: do test method call instead or Introspect call")
