The author takes no responsibility 13 * for the misuse/abuse of this program and provides it for the sole purpose 14 * of testing packet filter policies. This file maybe distributed freely 15 * providing it is not modified and that this notice remains in tact. 16 * 17 */ 18#ifndef __P 19# define __P(x) x 20#endif 21 22#include <net/if.h> 23 24#include "ipf.h" 25/* XXX: The following is needed by tcpip.h */ 26#include <netinet/ip_var.h> 27#include "netinet/tcpip.h" 28#include "ipt.h" 29 30extern int resolve(char *, char *); 31extern int arp(char *, char *); 32extern u_short chksum(u_short *, int); 33extern int send_ether(int, char *, int, struct in_addr); 34extern int send_ip(int, int, ip_t *, struct in_addr, int); 35extern int send_tcp(int, int, ip_t *, struct in_addr); 36extern int send_udp(int, int, ip_t *, struct in_addr); 37extern int send_icmp(int, int, ip_t *, struct in_addr); 38extern int send_packet(int, int, ip_t *, struct in_addr); 39extern int send_packets(char *, int, ip_t *, struct in_addr); 40extern u_short ipseclevel(char *); 41extern u_32_t buildopts(char *, char *, int); 42extern int addipopt(char *, struct ipopt_names *, int, char *); 43extern int initdevice(char *, int); 44extern int sendip(int, char *, int); 45extern struct tcpcb *find_tcp(int, struct tcpiphdr *); 46extern int ip_resend(char *, int, struct ipread *, struct in_addr, char *); 47 48extern void ip_test1(char *, int, ip_t *, struct in_addr, int); 49extern void ip_test2(char *, int, ip_t *, struct in_addr, int); 50extern void ip_test3(char *, int, ip_t *, struct in_addr, int); 51extern void ip_test4(char *, int, ip_t *, struct in_addr, int); 52extern void ip_test5(char *, int, ip_t *, struct in_addr, int); 53extern void ip_test6(char *, int, ip_t *, struct in_addr, int); 54extern void ip_test7(char *, int, ip_t *, struct in_addr, int); 55extern int do_socket(char *, int, struct tcpiphdr *, struct in_addr); 56extern int kmemcpy(char *, void *, int); 57 58#define KMCPY(a,b,c) kmemcpy((char *)(a), (void *)(b), (int)(c)) 59 60#ifndef OPT_RAW 61#define OPT_RAW 0x80000 62#endif 63
