* Add additional length checking, print unsigned lengths with %u.Guy Harris2010-08-161-11/+19

* Print AppleTalk layer-3 network numbers as 16-bit unsigned decimal numbers.Guy Harris2010-08-161-13/+9
| | | | | | | | | | | | | | Pick up from FreeBSD: revision 1.3 date: 1996/09/11 06:18:26; author: pst; state: Exp; lines: +9 -12 branches: 1.3.2; Print appletalk layer 3 addresses as 16 bit unsigned decimal numbers, not two 8 bit values. This conforms to industry standard. These changes have been sent back to LBL. Inside AppleTalk(R), Second Edition speaks of node numbers as 16-bit.
* Get rid of no-longer-valid comment.Guy Harris2010-08-161-8/+0
| | | | | | We no longer guarantee alignment in any printer routine; all printers must use the EXTRACT_ macros to extract integral quantities - and the Appletalk printers now do so.

* 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".
* Hoist a bunch of stuff that should be done by all if_print routines intoguy2002-12-191-16/+12
| | | | | | 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.
* The "__attribute__((packed))" tag on structures causes some files not toguy2002-12-111-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 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()".

* The infinite diversity of UNIX platforms is an eternal source of joy.guy2000-10-101-1/+2
| | | | | | | | | | | | | On some platforms (e.g., Solaris 2.5.1 and 2.6, at least), you have to include <netdb.h> to get MAXHOSTNAMELEN defined, including <sys/param.h> doesn't do it (on others, <netdb.h> doesn't help, and you have to include <sys/param.h>. Include <netdb.h> in some files, but, for "timed.h", just use 256 rather than MAXHOSTNAMELEN - the Berkeley time daemon protocol spec (in the timed source directory in various BSDs) says the packet includes "A zero-terminated string of up to 256 ASCII characters with the name of the machine sending the message."

Move other stuff used by dissectors from <netinet/if_ether.h> to "ether.h", along the lines of "fddi.h" and "token.h". Move ARP declarations from BSD include files to "print-arp.c". 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.
