According to include/qom/object.h:
/**
* object_property_get_str:
* @obj: the object
* @name: the name of the property
* @errp: returns an error if this function fails
*
* Returns: the value of the property, converted to a C string, or NULL if
* an error occurs (including when the property value is not a string).
* The caller should free the string.
*/
So I've checked all the call sites and found three places where the
string is obviously [*] leaked. Patch 2 and 3 fix very recent 2.12
commits, while patch 1 fixes a 2.4 commit (backported to 2.3.1).
Another potential candidate sits in query_memdev(), called during
the "info memdev" HMP and the "query-memdev" QMP commands, but
both take care of freeing the string eventually. Nothing to fix
there.
[*] allocated string is put in a local variable and not freed before
returning
