Unfortunately this also breaks compatiblity, we currently have:

struct ipt_owner_info {
    uid_t uid;
    gid_t gid;
    pid_t pid;
    pid_t sid;
    char comm[16];
    u_int8_t match, invert;     /* flags */
};

and

struct ip6t_owner_info {
    uid_t uid;
    gid_t gid;
    pid_t pid;
    pid_t sid;
    u_int8_t match, invert;     /* flags */
};

This is compatible with neither one.
