The name field of 'struct property' was really always supposed to be a malloc()ed string, that is owned by the structure. To avoid an extra strdup() for strings coming up from the lexer, build_property() and build_property_delete() expect to take such an already malloc()ed string, which means it's not correct to pass it a static string literal. That's a pretty non-obvious constraint, so a bunch of incorrect uses have crept in. Really, avoiding the extra dup from the lexer isn't a big enough benefit for this demonstrably dangerous interface. So change it to do the xstrdup() itself, removing the burden from callers. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
