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 # ifdef __STDC__ # define __P(x) x # else # define __P(x) () # endif #endif #include "ip_compat.h" #ifdef linux #include #endif #include "tcpip.h" #include "ipt.h" #include "ipf.h" extern int resolve __P((char *, char *)); extern int arp __P((char *, char *)); extern u_short chksum __P((u_short *, int)); extern int send_ether __P((int, char *, int, struct in_addr)); extern int send_ip __P((int, int, ip_t *, struct in_addr, int)); extern int send_tcp __P((int, int, ip_t *, struct in_addr)); extern int send_udp __P((int, int, ip_t *, struct in_addr)); extern int send_icmp __P((int, int, ip_t *, struct in_addr)); extern int send_packet __P((int, int, ip_t *, struct in_addr)); extern int send_packets __P((char *, int, ip_t *, struct in_addr)); extern u_short seclevel __P((char *)); extern u_32_t buildopts __P((char *, char *, int)); extern int addipopt __P((char *, struct ipopt_names *, int, char *)); extern int initdevice __P((char *, int, int)); extern int sendip __P((int, char *, int)); #ifdef linux extern struct sock *find_tcp __P((int, struct tcpiphdr *)); #else extern struct tcpcb *find_tcp __P((int, struct tcpiphdr *)); #endif extern int ip_resend __P((char *, int, struct ipread *, struct in_addr, char *)); extern void ip_test1 __P((char *, int, ip_t *, struct in_addr, int)); extern void ip_test2 __P((char *, int, ip_t *, struct in_addr, int)); extern void ip_test3 __P((char *, int, ip_t *, struct in_addr, int)); extern void ip_test4 __P((char *, int, ip_t *, struct in_addr, int)); extern void ip_test5 __P((char *, int, ip_t *, struct in_addr, int)); extern void ip_test6 __P((char *, int, ip_t *, struct in_addr, int)); extern void ip_test7 __P((char *, int, ip_t *, struct in_addr, int)); extern int do_socket __P((char *, int, struct tcpiphdr *, struct in_addr)); extern int openkmem __P((void)); extern int kmemcpy __P((char *, void *, int)); #define KMCPY(a,b,c) kmemcpy((char *)(a), (void *)(b), (int)(c)) #ifndef OPT_RAW #define OPT_RAW 0x80000 #endif
