For top-level qdev properties, this is always set and matches 'prop->name'. However, for list elements it is NULL, because each element of a list doesn't have a separate name. Passing a non-NULL value runs into assertion failures in the visitor code. Therefore, using 'name' in error messages is not right for property types that are used in lists, because "(null)" (or even a segfault) isn't very helpful to identify what QEMU is complaining about. Change netdev properties to use 'prop->name' instead, which will contain the name of the array property after switching array properties to lists in the external interface. (This is still not perfect, as it doesn't identify which element in the list caused the error, but strictly better than before.)

In external interfaces (-device on the command line and device_add in QMP), this interface was broken by commit f3558b1b ('qdev: Base object creation on QDict rather than QemuOpts') because QDicts are unordered and therefore it could happen that QEMU tried to set the indexed properties before setting the length, which fails and effectively makes array properties inaccessible. In particular, this affects the 'ports' property of the 'rocker' device, which used to be configured like this: -device rocker,len-ports=2,ports[0]=dev0,ports[1]=dev1 This patch reworks the external interface so that instead of using a separate top-level property for the length and for each element, we use a single true array property that accepts a list value. In the external interfaces, this is naturally expressed as a JSON list and makes array properties accessible again. The new syntax looks like this: -device '{"driver":"rocker","ports":["dev0","dev1"]}' Creating an array property on the command line without using JSON format is currently not possible. This could be fixed by switching from QemuOpts to a keyval parser, which however requires consideration of the compatibility implications. All internal users of devices with array properties go through qdev_prop_set_array() at this point, so updating it takes care of all of them.
