It's used to pass command line options to a copied argv. But there's no reason to make the copies as it's all used in the same function. It can simply use stack variables. In fact, it fixes a subtle double free issue. As parse_options() can move contents in argv[], some entries may point to the same item. So freeing all items in the argv could trigger a double free. With stack variables, we don't need to allocate and free them. Tested-by: Ian Rogers <irogers@google.com> Signed-off-by: Namhyung Kim <namhyung@kernel.org> |
