Move the code to handle the "-C" flag into "tcpdump.c" from "pcap-dump-trunc.c". Don't make the variables "dump_and_trunc()" manipulates external or even static; fill in a structure with their values and pass a pointer to that structure to "dump_and_trunc()". "dump_and_trunc()" will update the "pcap_dumper_t" pointer in that structure if it rotates capture files, so that the next call to "dump_and_trunc()" will supply the updated pointer (the previous code was just opening a new capture, but not updating the variable passed to "dump_and_trunc()"). Instead of duplicating an old version of the "pcap_dump()" code (a version that didn't write out time stamps as 32-bit seconds and microsecond values on platforms where the fields in a "struct timeval" are 64-bit) in "dump_and_trunc()", just call "pcap_dump()" from "dump_and_trunc()".

extern int snaplen;
We no longer use "packetp" for anything, so eliminate it. (If any 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 the 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".

extern void aarp_print(const u_char *, u_int);
Updates from Bruce Simpson: Fix numerous bugs in my AODV submission, red faces all round, mainly due to misunderstanding of EXTRACT_STRING() macro arguments (because these are macros, type checking didn't happen). AODV HELLO extensions are now correctly printed. The code is closer to FreeBSD's style guidelines. Don't use "u_char" and "u_long", use "u_int8_t" and "u_int32_t". "u_long" is definitely wrong as it's 64 bits on some platforms; "u_char" is safe, but the official tcpdump style uses "u_int8_t". At least according to the (long-since-expired) draft-perkins-aodv6-01, the V6 AODV messages have different message type values from the V4 ones in draft-ietf-manet-aodv-13. However, draft-ietf-manet-aodv-13 says that the only differences are in the addresses; we support both. Clean up the way we tell the AODV6 dissector that we're running atop IPv6 a bit. Use "udpipaddr_print()" if we're printing AODV packets as a result of saying "anything that matches this filter is AODV", rather than doing it ourselves under the assumption that it's running over IPv4.

Bring in KAME IPv6 tcpdump. replaces esp/ah/isakmp decoder. Hope I did not break anything. Portability on IPv4-only node needs checking, I'll do this very soon. (sorry for rather jumbo commit) XXx what is _FAVOR_BSD?

#ifdef INET6
Eliminate some unused parameters. Use const more. Use EXTRACT_* macros more. Use TCHECK* more. Use tok2str() to replace some home-grown workalikes. smb: - Get rid of private types, use tcpdump-defined types - Rename fdata and fdata1 to smb_fdata and smb_fdata1 to avoid conflict with IRIX library function.

From Kazushi Sugyo <sugyo@pb.jp.nec.com>: Here is a patch for draft-ietf-mobileip-ipv6-17. - print-mobility.c: Mobility header(MIPv6 defines a new IPv6 protocol) printing - added Routing header type 2 - ICMPv6 Home Agent Address Discovery and Mobile Prefix Sol., Adv. message update

"icmp6_rrenum_print()" doesn't use its "icmp6len" argument (and, as that just reflects the payload length, the snapshot length has been trimmed to correspond to it, so it doesn't need to check it merely to avoid running past the end of the IPv6 payload); get rid of it. Pass "icmp6_print()" the IPv6 payload length (i.e., the length of the ICMPv6 packet), rather than having it compre the length itself. Make the length argument to "icmp6_cksum()" unsigned, to match the value passed to it. Fix the lengths passed to "sctp_print()", "tcp_print()", and "udp_print()" (we update "len" in the header-processing loop to correspond to the remaining payload, so we just pass it to those routines).
