* Move some stuff that tried to make up for system headers from print-tcp.cfenner2001-05-091-40/+1
| | | | | to tcp.h, since don't use the system headers now anyway it was just making up for our own tcp.h.

| | | | | | | | | | checksum, fetch it by casting the pointer to "const u_int8_t *" rather than "const char *" - casting it to "const char *" causes it to be sign-extended, perhaps causing 16 1 bits to be added in at the top and, at least on big-endian platforms (where "htons()" does nothing, meaning it won't trim off the extra 16 bits) with signed "char"s (e.g., SPARC), causing the checksum to be computed incorrectly and causing it to incorrectly be reported as bad.

* put stripped-down version of ip6.h and icmp6.h into tcpdump tree.itojun2000-10-071-5/+4
| | | | | | | | ip6.h is almost normal RFC2292 header. icmp6.h has couple of extensions (not covered by RFC2292), like MLD, ICMPv6 nodeinfo, and router renumber. XXX how to synchronize with future kame changes?

* do not use integer bitfield when we care about the resulting member size.itojun2000-10-031-4/+4
| | | | | u_int x:4, y:4; will occupy sizeof(int) on some platforms, while it occupy 1 byte on some platforms. use macro to decode th_off.

* Add an "ip.h" header, to declare the IP stuff needed by dissectors, andguy2000-09-231-3/+3
| | | | | | | | | | | have dissectors include them rather than <netinet/ip.h> or <netinet/ip_var.h>, if they actually need that stuff. Put the declarations of the ICMP stuff directly into "print-icmp.c". Remove all unnecessary includes of <netinet/ip*.h> files. Copy the byte-order stuff from "nameser.h" into "tcp.h".

* Changes from Kevin Steves to print, in an RST segment, the payload asguy2000-07-291-8/+55
| | | | | | | | | | | | | | | | | | text, as per RFC 1122: 4.2.2.12 RST Segment: RFC-793 Section 3.4 A TCP SHOULD allow a received RST segment to include data. DISCUSSION It has been suggested that a RST segment could contain ASCII text that encoded and explained the cause of the RST. No standard has yet been established for such data. as some TCP implementations (e.g., HP-UX 11.0) do that. Clean up the code that prints the payload of non-RST segments.

* add print-ascii.c and print-telnet.c from netbsd.itojun1999-12-221-3/+9
| | | | | - add -X option for ascii printing. - telnet command sequences (ff xx xx) will be dumped with -vvv -X.
