* dismiss NETDISSECT_REWORKED macroDenis Ovsienko2015-03-221-1/+0
| | | | | | | The purpose of this macro was to enable the file-by-file switch to NDO, after which only tcpdump.c had a use of it and the definitions guarded by it. Update tcpdump.c not to require them any more and dismiss the unused definitions.
* clean K&R style up in function declarations a bitDenis Ovsienko2015-03-051-1/+2
| | | | The function body should have its opening brace on the next line.
* Only print the incorporated IP packet if there is one.Guy Harris2014-12-191-7/+5
| | | | | | Check for the ICMP types that *do* include an IP packet, rather than checking for a set that doesn't. This does a better job of handling unknown ICMP types.
* u_intN_t is dead, long live uintN_t.Guy Harris2014-04-231-40/+40
| | | | | | | | | And, as we require at least autoconf 2.61, and as autoconf 2.61 and later have AC_TYPE_UINTn_T and AC_TYPE_INTn_T macros, we use them to define the uintN_t and intN_t macros if the system doesn't define them for us. This lets us get rid of bitypes.h as well.
* Netdissectify the to-name resolution routines.Guy Harris2014-04-041-10/+10
| | | | | | | | Have them take a netdissect_options * argument, and get the "no name resolution" flag from it. Move the declaration of dnaddr_string to addrtoname.h, along with the other XXX-to-string routines.
* finalize some previous NDO conversionsDenis Ovsienko2014-03-261-1/+1
| | | | | | Eliminate a number of fputs(), putchar() and fflush() uses. Justify preprocessor directives. Don't typecast ND_PRINT() to void and fix some indentation.

* remove tcpdump's own CVS keywordsDenis Ovsienko2014-01-031-5/+0
| | | | | | Remove lots of $Header's and a few $Id's that all belong to the former CVS repository of tcpdump itself. These keywords have been frozen since the migration to git in late 2008.

* justify declarations of struct tok arraysDenis Ovsienko2013-09-241-3/+3
| | | | | | Make sure all of them are declared const and most of them -- static. Proper declaration of token arrays is a common review point for new code that is based on existing decoders. Thus fix the issue at its root.
* Go with Wireshark's Internet checksum routine.Guy Harris2011-06-131-7/+14
| | | | | | | | | | | | | The Wireshark routine is based on the BSD in-kernel portable checksum routine (thus BSD-licensed); it takes a vector of pointers and lengths and checksums the concatenation of the buffers in question (just as the BSD in-kernel routine checksums a chain of mbufs). This simplifies the "with a pseudo-header" checksums; hopefully it'll fix up the problems being seen on some big-endian platforms, which might be due to hand-calculating some or all of the checksum and doing so incorrectly. It also gets rid of some code that might be dereferencing unaligned pointers.

| | | | | | | not all implementations correctly set the length field in the ICMP header as per draft-bonica-internet-icmp-08. if the length field is not set then simply check the checksum.
* rework on the ICMP MPLS extension code:hannes2006-12-121-30/+76
| | | | | | | - preserve the snapend pointer as it may get overwritten by calling the IP printer - protect against infinite loops inside the MPLS extension printer. - detect present of an MPLS extension header by introducing a length field to the ICMP header as per draft-bonica-internet-icmp-08.

* 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".
* Add a new "ipproto.h" header file, with definitions of IP protocol typeguy2003-06-071-1/+2

* The "__attribute__((packed))" tag on structures causes some files not toguy2002-12-111-18/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 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."
