* Fix plurals in packet count messages.Guy Harris2011-03-081-1/+1
| | | | | | | | Based on a patch from cr4ckn@sourceforge.net, but with a macro PLURAL_SUFFIX() defined to return either "s" or "" (rather than possibly printing a NUL character with %c), and with that macro used in a couple of cases where the equivalent had been done by hand, and with one case the patch missed fixed as well.
* Don't directly fetch multi-byte integers from packets.Guy Harris2010-02-211-1/+1
| | | | | | | | Use the EXTRACT_ macros to extract multi-byte integral values from packets, rather than just dereferencing pointers into the packet; there is no guarantee that the packet data will be aligned on the right boundary, and there is no guarantee that, if they're not, a direct access will work correctly.

* Add an "fn_printzp()" routine for printing null-padded strings (stringsguy2005-05-061-3/+6
| | | | | | | | | | | | | | | 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.

* 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".

* The "__attribute__((packed))" tag on structures causes some files not toguy2002-12-111-25/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* On some platforms, "ntohl()" returns a "long" or "unsigned long"; castguy2002-11-101-7/+7

* Remove #if 0 sectionsfenner2001-06-151-7/+1
| | | | | | | | Finish converting over to having the caller print the IP address (except for UDP, TCP and SCTP). This consists mostly of removing places where the IP address is printed, both in the big "case" in ip_print() and in the individual printers. Also fix a couple of spacing bugs.

| | | | | | | | | | | 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".
