|
|
*
|

*
|

* dli_family is a Solaris address family value, so it's 2 for IPv4

*
|
|

* dli_zdst is the zone identifier for the destination of the packet.
|

|
* A zone number of 0 is the global zone; a zone number of 0xffffffff

|
|
* didn't know that the right way to get a link-layer header type is to
|
|
* ask tcpdump.org for one, or knew and didn't care, so they just
|
|
* used DLT_USER2, which causes problems for everything except for
|
|
* their version of tcpdump.
|
|
*
|
|
* So I'll just give them one; hopefully this will show up in a
|
|
* libpcap release in time for them to get this into 10.10 Big Sur
|
|
* or whatever Mavericks' successor is called. LINKTYPE_PKTAP
|
|
* will be 258 *even on OS X*; that is *intentional*, so that
|
|
* PKTAP files look the same on *all* OSes (different OSes can have
|
|
* different numerical values for a given DLT_, but *MUST NOT* have
|
|
* different values for what goes in a file, as files can be moved
|
|
* between OSes!).
|
|
*
|
|
* When capturing, on a system with a Darwin-based OS, on a device
|
|
* that returns 149 (DLT_USER2 and Apple's DLT_PKTAP) with this
|
|
* version of libpcap, the DLT_ value for the pcap_t will be DLT_PKTAP,
|
|
* and that will continue to be DLT_USER2 on Darwin-based OSes. That way,
|
|
* binary compatibility with Mavericks is preserved for programs using
|
|
* this version of libpcap. This does mean that if you were using
|
|
* DLT_USER2 for some capture device on OS X, you can't do so with
|
|
* this version of libpcap, just as you can't with Apple's libpcap -
|
|
* on OS X, they define DLT_PKTAP to be DLT_USER2, so programs won't
|
|
* be able to distinguish between PKTAP and whatever you were using
|
|
* DLT_USER2 for.
|
|
*
|
|
* If the program saves the capture to a file using this version of
|
|
* libpcap's pcap_dump code, the LINKTYPE_ value in the file will be
|
|
* LINKTYPE_PKTAP, which will be 258, even on Darwin-based OSes.
|
|
* That way, the file will *not* be a DLT_USER2 file. That means
|
|
* that the latest version of tcpdump, when built with this version
|
|
* of libpcap, and sufficiently recent versions of Wireshark will
|
|
* be able to read those files and interpret them correctly; however,
|
|
* Apple's version of tcpdump in OS X 10.9 won't be able to handle
|
|
* them. (Hopefully, Apple will pick up this version of libpcap,
|
|
* and the corresponding version of tcpdump, so that tcpdump will
|
|
* be able to handle the old LINKTYPE_USER2 captures *and* the new
|
|
