            Bug ID: 229665
           Summary: src/sys/netpfil/ipfw/ip_fw_sockopt.c:304: possible bad
                    size in malloc ?
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org

src/sys/netpfil/ipfw/ip_fw_sockopt.c:304]: (warning) Size of pointer 'idxma=
p'
used instead of size of its data.

Source code is

        int *idxmap, *idxmap_back;

        idxmap =3D malloc(65536 * sizeof(uint32_t *), M_IPFW,
            M_WAITOK | M_ZERO);
        idxmap_back =3D malloc(65536 * sizeof(uint32_t *), M_IPFW,
            M_WAITOK | M_ZERO);

maybe better code

        int *idxmap, *idxmap_back;

        idxmap =3D malloc(65536 * sizeof(int), M_IPFW,
            M_WAITOK | M_ZERO);
        idxmap_back =3D malloc(65536 * sizeof(int), M_IPFW,
            M_WAITOK | M_ZERO);
