From Albert Chin: 1. On AIX, AC_LBL_C_INLINE detected the compiler supported the inline keyword which is wrong. AC_C_INLINE from autoconf-2.59 worked. 2. AC_CHECK_TYPE from autoconf-2.5x is no longer broken. Replaced AC_LBL_CHECK_TYPE with it, mainly to use <sys/bitypes.h> for Tru64 UNIX where some of the u_int#_t types are defined. 3. Tru64 UNIX 4.0D doesn't support %llx; however, it does support %lx. 4. Added <stdint.h> to interface.h for int#_t types on Tru64 UNIX 4.0D (required for missing/snprintf.c). 5. Reworked includes in tcpdump-stdinc.h for int#_t types.

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()".

Add an "fn_printzp()" routine for printing null-padded strings (strings with a maximum length, where a string shorter than that length is padded with NULs), as "fn_print()" won't handle the maximum length *and* the snapshot length and "fn_printn()" won't stop on a null string. Use it where appropriate. Always pass "snapend" to "fn_print()" and "fn_printn()" if they're passed a pointer into the packet data; only pass NULL if they're being handed a pointer into a buffer that's not part of the packet data. Always check the return value of "fn_print()", "fn_printn()", and "fn_printzp()" if they're passed "snapend", and do the appropriate string termination and "packet truncated" indication if they return 1.

Make "snap_print()" handle fetching and printing the OUI. Don't copy the LLC header to a "struct llc", just construct the individual fields. Fetch the control field early in the dissection process, and check to make sure we have at least 4 bytes of LLC header if it's not a U frame. Fetch both bytes of the control field for I and S frames, and display all 4 hex digits of it. Only dissect UI frames as BPDUs, and pass the BPDU dissector a pointer to the beginning of the BPDU, not the beginning of the LLC header - not all BPDUs are encapsulated in LLC headers. Only dissect UI frames as IP packets. Do bounds checking in "snap_print()".

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.

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".

"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).

Add a flag to suppress the "default_print()" call made in various link-layer print routines if no other print routine claimed the packet. Test whether that flag is set rather than testing whether neither of -x or -q were specified, and have -x, -q, *and* -X set that flag, so that -X suppresses it just as -x does. That way you don't get those pckets dumped twice if -X was specified.
