308 | * |
309 | * On 2004-02-25, a FreeBSD checkin to sys/net/bpf.h was made that |
310 | * assigned 121 as DLT_PFSYNC. Its libpcap does DLT_ <-> LINKTYPE_ |
311 | * mapping, so it probably supports capturing on the pfsync device |
312 | * but not saving the captured data to a pcap file. |
313 | * |
314 | * OpenBSD, from which pf came, however, uses 18 for DLT_PFSYNC; |
315 | * their libpcap does no DLT_ <-> LINKTYPE_ mapping, so it would |
316 | * use 18 in pcap files as well. |
317 | * |
318 | * NetBSD and DragonFly BSD also use 18 for DLT_PFSYNC; their |
319 | * libpcaps do DLT_ <-> LINKTYPE_ mapping, and neither has an entry |
320 | * for DLT_PFSYNC, so it might not be able to write out dump files |
321 | * with 18 as the link-layer header type. (Earlier versions might |
322 | * not have done mapping, in which case they'd work the same way |
323 | * OpenBSD does.) |
324 | * |
325 | * Mac OS X defines it as 18, but doesn't appear to use it as of |
326 | * Mac OS X 10.7.3. Its libpcap does DLT_ <-> LINKTYPE_ mapping. |

336 | * header type of a savefile won't, when built and run on FreeBSD, |
337 | * be able to distinguish between LINKTYPE_PFSYNC and LINKTYPE_HHDLC |

919 | * Solaris ipnet pseudo-header; requested by Darren Reed <Darren.Reed@Sun.COM>. |
920 | * |
921 | * The pseudo-header starts with a one-byte version number; for version 2, |
922 | * the pseudo-header is: |
923 | * |
924 | * struct dl_ipnetinfo { |
925 | * u_int8_t dli_version; |
926 | * u_int8_t dli_family; |
927 | * u_int16_t dli_htype; |
928 | * u_int32_t dli_pktlen; |
929 | * u_int32_t dli_ifindex; |
930 | * u_int32_t dli_grifindex; |
931 | * u_int32_t dli_zsrc; |
932 | * u_int32_t dli_zdst; |
933 | * }; |
934 | * |
935 | * dli_version is 2 for the current version of the pseudo-header. |
936 | * |
937 | * dli_family is a Solaris address family value, so it's 2 for IPv4 |
938 | * and 26 for IPv6. |
939 | * |
940 | * dli_htype is a "hook type" - 0 for incoming packets, 1 for outgoing |
941 | * packets, and 2 for packets arriving from another zone on the same |
942 | * machine. |
943 | * |
944 | * dli_pktlen is the length of the packet data following the pseudo-header |
945 | * (so the captured length minus dli_pktlen is the length of the |
946 | * pseudo-header, assuming the entire pseudo-header was captured). |
947 | * |
948 | * dli_ifindex is the interface index of the interface on which the |
949 | * packet arrived. |
950 | * |
951 | * dli_grifindex is the group interface index number (for IPMP interfaces). |
952 | * |
953 | * dli_zsrc is the zone identifier for the source of the packet. |
954 | * |
955 | * dli_zdst is the zone identifier for the destination of the packet. |
956 | * |
957 | * A zone number of 0 is the global zone; a zone number of 0xffffffff |
958 | * means that the packet arrived from another host on the network, not |
959 | * from another zone on the same machine. |
960 | * |
961 | * An IPv4 or IPv6 datagram follows the pseudo-header; dli_family indicates |
962 | * which of those it is. |

1197 | * Sadly, the folks at Apple either had no clue that the DLT_USERn values |
1198 | * are for internal use within an organization and partners only, and |
1199 | * didn't know that the right way to get a link-layer header type is to |
1200 | * ask tcpdump.org for one, or knew and didn't care, so they just |
1201 | * used DLT_USER2, which causes problems for everything except for |
1202 | * their version of tcpdump. |
1203 | * |
1204 | * So I'll just give them one; hopefully this will show up in a |
1205 | * libpcap release in time for them to get this into 10.10 Big Sur |
1206 | * or whatever Mavericks' successor is called. LINKTYPE_PKTAP |
1207 | * will be 258 *even on OS X*; that is *intentional*, so that |
1208 | * PKTAP files look the same on *all* OSes (different OSes can have |
1209 | * different numerical values for a given DLT_, but *MUST NOT* have |
1210 | * different values for what goes in a file, as files can be moved |
1211 | * between OSes!). |
1212 | * |
1213 | * When capturing, on a system with a Darwin-based OS, on a device |
1214 | * that returns 149 (DLT_USER2 and Apple's DLT_PKTAP) with this |
1215 | * version of libpcap, the DLT_ value for the pcap_t will be DLT_PKTAP, |
1216 | * and that will continue to be DLT_USER2 on Darwin-based OSes. That way, |
1217 | * binary compatibility with Mavericks is preserved for programs using |
1218 | * this version of libpcap. This does mean that if you were using |
1219 | * DLT_USER2 for some capture device on OS X, you can't do so with |
1220 | * this version of libpcap, just as you can't with Apple's libpcap - |
1221 | * on OS X, they define DLT_PKTAP to be DLT_USER2, so programs won't |
1222 | * be able to distinguish between PKTAP and whatever you were using |
1223 | * DLT_USER2 for. |
1224 | * |
1225 | * If the program saves the capture to a file using this version of |
1226 | * libpcap's pcap_dump code, the LINKTYPE_ value in the file will be |
1227 | * LINKTYPE_PKTAP, which will be 258, even on Darwin-based OSes. |
1228 | * That way, the file will *not* be a DLT_USER2 file. That means |
1229 | * that the latest version of tcpdump, when built with this version |
1230 | * of libpcap, and sufficiently recent versions of Wireshark will |
1231 | * be able to read those files and interpret them correctly; however, |
1232 | * Apple's version of tcpdump in OS X 10.9 won't be able to handle |
1233 | * them. (Hopefully, Apple will pick up this version of libpcap, |
1234 | * and the corresponding version of tcpdump, so that tcpdump will |
1235 | * be able to handle the old LINKTYPE_USER2 captures *and* the new |
1236 | * LINKTYPE_PKTAP captures.) |
