297 * On 2004-02-25, a FreeBSD checkin to sys/net/bpf.h was made that
298 * assigned 121 as DLT_PFSYNC.  In current versions, its libpcap
299 * does DLT_ <-> LINKTYPE_ mapping, mapping DLT_PFSYNC to a
300 * LINKTYPE_PFSYNC value of 246, so it should write out DLT_PFSYNC
301 * dump files with 246 as the link-layer header type.  (Earlier
302 * versions might not have done mapping, in which case they would
303 * have written them out with a link-layer header type of 121.)
304 *
305 * OpenBSD, from which pf came, however, uses 18 for DLT_PFSYNC;
306 * its libpcap does no DLT_ <-> LINKTYPE_ mapping, so it would
307 * write out DLT_PFSYNC dump files with use 18 as the link-layer
308 * header type.
309 *
310 * NetBSD, DragonFly BSD, and Darwin also use 18 for DLT_PFSYNC; in
311 * current versions, their libpcaps do DLT_ <-> LINKTYPE_ mapping,
312 * mapping DLT_PFSYNC to a LINKTYPE_PFSYNC value of 246, so they
313 * should write out DLT_PFSYNC dump files with 246 as the link-layer
314 * header type.  (Earlier versions might not have done mapping,
315 * in which case they'd work the same way OpenBSD does, writing
316 * them out with a link-layer header type of 18.)
317 *
318 * We'll define DLT_PFSYNC as:
319 *
320 *    18 on NetBSD, OpenBSD, DragonFly BSD, and Darwin;
321 *
322 *    121 on FreeBSD;
323 *
324 *    246 everywhere else.
325 *
326 * We'll define DLT_HHDLC as 121 on everything except for FreeBSD;
327 * anybody who wants to compile, on FreeBSD, code that uses DLT_HHDLC
328 * is out of luck.
329 *
330 * We'll define LINKTYPE_PFSYNC as 246 on *all* platforms, so that
331 * savefiles written using *this* code won't use 18 or 121 for PFSYNC,
332 * they'll all use 246.
333 *
334 * Code that uses pcap_datalink() to determine the link-layer header
335 * type of a savefile won't, when built and run on FreeBSD, be able
336 * to distinguish between LINKTYPE_PFSYNC and LINKTYPE_HHDLC capture
337 * files, as pcap_datalink() will give 121 for both of them.  Code
338 * that doesn't, such as the code in Wireshark, will be able to
339 * distinguish between them.
340 *
341 * FreeBSD's libpcap won't map a link-layer header type of 18 - i.e.,
342 * DLT_PFSYNC files from OpenBSD and possibly older versions of NetBSD,
343 * DragonFly BSD, and macOS - to DLT_PFSYNC, so code built with FreeBSD's
344 * libpcap won't treat those files as DLT_PFSYNC files.
345 *
346 * Other libpcaps won't map a link-layer header type of 121 to DLT_PFSYNC;
347 * this means they can read DLT_HHDLC files, if any exist, but won't
348 * treat pcap files written by any older versions of FreeBSD libpcap that

1255 * Sadly, the folks at Apple either had no clue that the DLT_USERn values
1256 * are for internal use within an organization and partners only, and
1257 * didn't know that the right way to get a link-layer header type is to
1258 * ask tcpdump.org for one, or knew and didn't care, so they just
1259 * used DLT_USER2, which causes problems for everything except for
1260 * their version of tcpdump.
1261 *
1262 * So I'll just give them one; hopefully this will show up in a
1263 * libpcap release in time for them to get this into 10.10 Big Sur
1264 * or whatever Mavericks' successor is called.  LINKTYPE_PKTAP
1265 * will be 258 *even on macOS*; that is *intentional*, so that
1266 * PKTAP files look the same on *all* OSes (different OSes can have
1267 * different numerical values for a given DLT_, but *MUST NOT* have
1268 * different values for what goes in a file, as files can be moved
1269 * between OSes!).
1270 *
1271 * When capturing, on a system with a Darwin-based OS, on a device
1272 * that returns 149 (DLT_USER2 and Apple's DLT_PKTAP) with this
1273 * version of libpcap, the DLT_ value for the pcap_t  will be DLT_PKTAP,
1274 * and that will continue to be DLT_USER2 on Darwin-based OSes. That way,
1275 * binary compatibility with Mavericks is preserved for programs using
1276 * this version of libpcap.  This does mean that if you were using
1277 * DLT_USER2 for some capture device on macOS, you can't do so with
1278 * this version of libpcap, just as you can't with Apple's libpcap -
1279 * on macOS, they define DLT_PKTAP to be DLT_USER2, so programs won't
1280 * be able to distinguish between PKTAP and whatever you were using
1281 * DLT_USER2 for.
1282 *
1283 * If the program saves the capture to a file using this version of
1284 * libpcap's pcap_dump code, the LINKTYPE_ value in the file will be
1285 * LINKTYPE_PKTAP, which will be 258, even on Darwin-based OSes.
1286 * That way, the file will *not* be a DLT_USER2 file.  That means
1287 * that the latest version of tcpdump, when built with this version
1288 * of libpcap, and sufficiently recent versions of Wireshark will
1289 * be able to read those files and interpret them correctly; however,
1290 * Apple's version of tcpdump in OS X 10.9 won't be able to handle
1291 * them.  (Hopefully, Apple will pick up this version of libpcap,
1292 * and the corresponding version of tcpdump, so that tcpdump will
1293 * be able to handle the old LINKTYPE_USER2 captures *and* the new
1294 * LINKTYPE_PKTAP captures.)
