* Have the configure script arrange that the Makefile define _U_guy2003-11-161-4/+4
| | | | | | | | | | appropriately, and that GNUmakefile and the MSVC++ project file define it apppriately, as we do with libpcap, rather than defining it in "interface.h". Undo the rcsid-shuffling and addition of extra #includes, as we no longer need to arrange that "interface.h" be included before using _U_ in an RCS ID or copyright.
* From Neil Spring:guy2003-11-151-1/+1
| | | | | | | | | | | use "_U_" in the definitions of "rcsid[]", to eliminate complaints about those variables being unused; move the definitions after the include of "interface.h", or add an include of "interface.h", so that "_U_" is defined. Include "config.h" before including "tcpdump-stdinc.h" in "missing/datalinks.c".

* Check the AF_ value rather than the IP header on packets; the packetsguy2003-02-051-19/+76
| | | | | | | | | | aren't necessarily IP packets. Support several different versions of AF_INET6 from various BSDs. Handle OSI, AppleTalk, and IPX. Handle unknown AF_ values the way unknown protocol types are handled in other print routines - print the raw packet payload.
* Hoist a bunch of stuff that should be done by all if_print routines intoguy2002-12-191-20/+4
| | | | | | tcpdump.c. Have if_print routines return the length of the link-layer header, so that the common code knows how to skip the link-layer header when printing the packet in hex/ASCII.
* Add a new routine "default_print_packet()", which takes a pointer to theguy2002-12-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | beginning of the raw packet data, the captured length of the raw packet data, and the length of the link-layer header, and: if "-e" was specified, prints all the raw packet data; if "-e" was not specified, prints all the raw packet data past the link-layer header, if there is any. Use that routine in all the "xxx_if_print()" routines if "-x" was specified. Make "arcnet_encap_print()" static - it's not used outside "print-arcnet.c". Add missing info printing code to "atm_if_print()". Print the packet data in "lane_if_print()", not in "lane_print()", as "lane_print()" can be called from other "xxx_if_print()" routines, and those routines will also print the packet data if "-x" was specified - no need to print it twice.
* We no longer use "packetp" for anything, so eliminate it. (If anyguy2002-12-181-5/+4
| | | | | | | | | | | | | dissector really needs source and destination MAC addresses, we should make global pointers to them - which would be null for packets lacking MAC addresses, so dissectors that need them will need to do something sensible if those pointers are null.) Don't fake up an Ethernet header if there aren't any MAC addresses to use when faking it up. "bp_chaddr" in "print-bootp.c" is an array, so "bp->bp_chaddr" cannot be null, and there's no need to test for it not being null.
* Get rid of the "-Wno-unused" flag, and fix up most of theguy2002-09-051-2/+2
| | | | | | | | | | | | | | | unused-parameter problems reported by GCC. Add an _U_ tag to label parameters as unused if the function is called through a pointer (so that you can't change its signature by removing parameters) or if there are unused parameters only because the function isn't complete. Add some additional bounds checks the necessity for which was revealed while cleaning up unused-parameter problems. Make some routines static. "lcp_print()", defined in "print-lcp.c", isn't called anywhere - "print-ppp.c" has the code to dissect LCP. Get rid of "print-lcp.c".

* Put the infodelay wrapping into the remaining "XXX_if_print()" routines.guy2001-07-051-1/+5
| | | | | | | | | | | | | | Split the Cisco HDLC printer into "chdlc_if_print()", which does the stuff expected of a low-level print routine (printing the time stamp, printing the final newline, doing the infodelay stuff) and "chdlc_print()", which doesn't do that stuff. This lets us clean up "ppp_hdlc_if_print()" a bit - it can just print the time stamp at the beginning, and do the infodelay stuff at the end, without having to treat Cisco HDLC specially by skipping the time stamp printing. (This also ensures that the time stamp is always printed, which wasn't the case before.) Print the missing final newline in "pppoe_if_print()".
* Handle DLT_NULL correctly - the AF_ value is in host byte order, whichguy2000-12-161-11/+35
| | | | | | | | | | | | | | | | | | | | | may not be *our* byte order if we're reading a capture file from another machine; we currently handle that by checking whether it looks like an integer < 65536 or not and, if it's not, byte-swap it. This also lets us handle OpenBSD DLT_LOOP as well - it's like DLT_NULL except that the AF_ value is in *network* byte order. (Old-style Linux loopback captures were also DLT_NULL, but the header had an Ethernet type in it; there have also been captures where the header was a PPP header. For now, we just continue to assume that all DLT_NULL packets are IP, and check the IP version field to decide whether it's IPv4, IPv6, or something else. We may want to consider adopting Ethereal's heuristics, which would at least mean we wouldn't be reporting bogus packet types for old-style Linux loopback captures and those weird PPP - ISDN4BSD? - captures, although the version of libpcap that goes with this version of tcpdump doesn't produce bogus DLT_NULL captures for Linux loopback devices.)
* If "-n" is specified along with "-e", print the address family value asguy2000-12-041-18/+19
| | | | | | | | | | | | | "AF <n>" for DLT_NULL captures. Print the packet length for DLT_NULL captures when "-e" is specified (somebody complained on "freebsd-isp" about the lack of any packet length from tcpdump when capturing traffic on a "tunX" device). Make sure we always print the packet length on PPP when "-e" is specified (the person in question also complained that the packet length disappeared between FreeBSD 2.2.8 and FreeBSD 3.4, which was the result of a new "print-ppp.c" that didn't print the length).

Remove from dissectors includes of <netinet/if_ether.h>, and add includes of "ethertype.h" and/or "ether.h" as necessary. Get rid of configuration options that test declarations now made in "ether.h" or "print-arp.c", as those declarations are now under our control, not the OS's control.
