* Add a flag to suppress the "default_print()" call made in variousguy2005-07-071-2/+2
| | | | | | | | 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.

* 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:guy2003-11-151-4/+4
| | | | | | | | | | | 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".

| | | | | | | | | for it to check the protocol number in the IP header. Have the IPv6 dissector call the SCTP dissector for SCTP packets. Get rid of the definition of IPPROTO_SCTP in sctpConstants.h, so we don't have problems if <netinet/in.h> also defines it.
* The "__attribute__((packed))" tag on structures causes some files not toguy2002-12-111-28/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | compile with Sun C, as "interface.h" isn't being included before the structures are being declared. Furthermore, in the files that Sun C *can* compile, it doesn't cause Sun C to generate code that's safe with unaligned accesses, as "__attribute__" is defined as a do-nothing macro with compilers that don't support it. Therefore, we get rid of that tag on the structures to which it was added, and instead use "EXTRACT_16BIT()" and "EXTRACT_32BIT()" to fetch 16-bit and 32-bit big-endian quantities from packets. We also fix some other references to multi-byte quantities to get rid of code that tries to do unaligned loads on platforms that don't support them. We also throw in a hack that makes those macros use "__attribute__((packed))" on structures containing only one 16-bit or 32-bit integer to get the compiler to generate unaligned-safe code rather than doing it by hand. (GCC on SPARC produces the same code that doing it by hand does; I don't know if GCC on any other big-endian strict-alignment processor generates better code for that case. On little-endian processors, as "ntohs()" and "ntohl()" might be functions, that might actually produce worse code.) Fix some places to use "%u" rather than "%d" to print unsigned quantities.

| | | | | | | so, it doesn't need to provide incomplete definitions of "struct mbuf" or "struct rtentry", either. If it *does* include <net/if.h>, it appears to fail to compile on at least some versions of AIX; remove the include and the incomplete definitions.
