/* $FreeBSD$ */ /* * ipsend.h (C) 1997-1998 Darren Reed * * This was written to test what size TCP fragments would get through * various TCP/IP packet filters, as used in IP firewalls. In certain * conditions, enough of the TCP header is missing for unpredictable * results unless the filter is aware that this can happen. * * The author provides this program as-is, with no gaurantee for its * suitability for any specific purpose. The author takes no responsibility * for the misuse/abuse of this program and provides it for the sole purpose * of testing packet filter policies. This file maybe distributed freely * providing it is not modified and that this notice remains in tact. * */ #ifndef __P # define __P(x) x #endif #include #include "ipf.h" /* XXX: The following is needed by tcpip.h */ #include #include "netinet/tcpip.h" #include "ipt.h" extern int resolve(char *, char *); extern int arp(char *, char *); extern u_short chksum(u_short *, int); extern int send_ether(int, char *, int, struct in_addr); extern int send_ip(int, int, ip_t *, struct in_addr, int); extern int send_tcp(int, int, ip_t *, struct in_addr); extern int send_udp(int, int, ip_t *, struct in_addr); extern int send_icmp(int, int, ip_t *, struct in_addr); extern int send_packet(int, int, ip_t *, struct in_addr); extern int send_packets(char *, int, ip_t *, struct in_addr); extern u_short ipseclevel(char *); extern u_32_t buildopts(char *, char *, int); extern int addipopt(char *, struct ipopt_names *, int, char *); extern int initdevice(char *, int); extern int sendip(int, char *, int); extern struct tcpcb *find_tcp(int, struct tcpiphdr *); extern int ip_resend(char *, int, struct ipread *, struct in_addr, char *); extern void ip_test1(char *, int, ip_t *, struct in_addr, int); extern void ip_test2(char *, int, ip_t *, struct in_addr, int); extern void ip_test3(char *, int, ip_t *, struct in_addr, int); extern void ip_test4(char *, int, ip_t *, struct in_addr, int); extern void ip_test5(char *, int, ip_t *, struct in_addr, int); extern void ip_test6(char *, int, ip_t *, struct in_addr, int); extern void ip_test7(char *, int, ip_t *, struct in_addr, int); extern int do_socket(char *, int, struct tcpiphdr *, struct in_addr); extern int kmemcpy(char *, void *, int); #define KMCPY(a,b,c) kmemcpy((char *)(a), (void *)(b), (int)(c)) #ifndef OPT_RAW #define OPT_RAW 0x80000 #endif
