/************************************************************************************ Filename : sendpacket.h Author : liuqingyun Time : 2007-05 实现说明： （1）参照libnet1.02a版本实现如下函数，基本未变 sendpacket_build_ip sendpacket_build_ipv4 sendpacket_build_tcp sendpacket_build_udp sendpacket_do_checksum sendpacket_init_packet sendpacket_destroy_packet 功能说明： （1）能够发送tcp,udp,ipv4数据包； （2）能够统计每个socket上面发送的包数，字节数； （3）可以全局公用sendpacketTool，不用每次调用时分配长度， （4）如果全局使用sendpacketTool,为了安全起见，每次调用前应该先检测要发送的长度，不超过初始化分配的长度； （5）不支持选项字段，不支持其它协议报文； *************************************************************************************/ #ifndef __SENDPACKET_H_ #define __SENDPACKET_H_ /* * Data-link level type codes. */ #define DLT_NULL 0 /* no link-layer encapsulation */ #define DLT_EN10MB 1 /* Ethernet (10Mb) */ #define DLT_EN3MB 2 /* Experimental Ethernet (3Mb) */ #define DLT_AX25 3 /* Amateur Radio AX.25 */ #define DLT_PRONET 4 /* Proteon ProNET Token Ring */ #define DLT_CHAOS 5 /* Chaos */ #define DLT_IEEE802 6 /* IEEE 802 Networks */ #define DLT_ARCNET 7 /* ARCNET */ #define DLT_SLIP 8 /* Serial Line IP */ #define DLT_PPP 9 /* Point-to-point Protocol */ #define DLT_FDDI 10 /* FDDI */ #define DLT_ATM_RFC1483 11 /* LLC/SNAP encapsulated atm */ #define DLT_RAW 12 /* raw IP */ #ifndef DLT_SLIP_BSDOS #define DLT_SLIP_BSDOS 13 /* BSD/OS Serial Line IP */ #endif #ifndef DLT_PPP_BSDOS #define DLT_PPP_BSDOS 14 /* BSD/OS Point-to-point Protocol */ #endif #define SENDPACKET_LIL_ENDIAN 1 #include #include #include #include #include #include #include #if defined(HAVE_SYS_SOCKIO_H) && !defined(SIOCGIFADDR) #include #endif #include #include #include #include #include #include #include #include #if !(__linux__) #include #else /* __linux__ */ #if (HAVE_NET_ETHERNET_H) #include #endif /* HAVE_NET_ETHERNET_H */ #endif /* __linux__ */ #include #include #include #if (__linux__) && !(__GLIBC__) /* * We get multiple definitions of IGMP_AGE_THRESHOLD if we include netinet. */ #include #else #include #endif #include #include #include #include #include #ifdef CAPTURE_MODE_PFRING #include #endif #define SENDPACKET_ARP_H 0x1c /* ARP header: 28 bytes */ #define SENDPACKET_ETH_H 0xe /* Etherner header: 14 bytes */ #define SENDPACKET_IP_H 0x14 /* IP header: 20 bytes */ /* See sendpacket-ospf.h for OSPF related header sizes */ #define SENDPACKET_RIP_H 0x18 /* RIP header base: 24 bytes */ #define SENDPACKET_TCP_H 0x14 /* TCP header: 20 bytes */ #define SENDPACKET_UDP_H 0x8 /* UDP header: 8 bytes */ /* * Standard (IPv4) header sizes in bytes. */ #define SENDPACKET_ICMP_H 0x4 /* ICMP header base: 4 bytes */ #define SENDPACKET_ICMP_ECHO_H 0x8 /* ICMP_ECHO header: 8 bytes */ #define SENDPACKET_ICMP_MASK_H 0xc /* ICMP_MASK header: 12 bytes */ #define SENDPACKET_ICMP_UNREACH_H 0x8 /* ICMP_UNREACH header: 8 bytes */ #define SENDPACKET_ICMP_TIMXCEED_H 0x8 /* ICMP_TIMXCEED header: 8 bytes */ #define SENDPACKET_ICMP_REDIRECT_H 0x8 /* ICMP_REDIRECT header: 8 bytes */ #define SENDPACKET_ICMP_TS_H 0x14 /* ICMP_TIMESTAMP headr:20 bytes */ /* * IPv4 packet header prototype. */ struct sendpacket_ip_hdr { #if (SENDPACKET_LIL_ENDIAN) u_int8_t ip_hl:4, /* header length */ ip_v:4; /* version */ #endif #if (SENDPACKET_BIG_ENDIAN) u_int8_t ip_v:4, /* version */ ip_hl:4; /* header length */ #endif u_int8_t ip_tos; /* type of service */ u_int16_t ip_len; /* total length */ u_int16_t ip_id; /* identification */ u_int16_t ip_off; #ifndef IP_RF #define IP_RF 0x8000 /* reserved fragment flag */ #endif #ifndef IP_DF #define IP_DF 0x4000 /* dont fragment flag */ #endif #ifndef IP_MF #define IP_MF 0x2000 /* more fragments flag */ #endif #ifndef IP_OFFMASK #define IP_OFFMASK 0x1fff /* mask for fragmenting bits */ #endif u_int8_t ip_ttl; /* time to live */ u_int8_t ip_p; /* protocol */ u_int16_t ip_sum; /* checksum */ struct in_addr ip_src, ip_dst; /* source and dest address */ }; /* * Ethernet packet header prototype.
