* Kerberos: Print the protocol nameFrancois-Xavier Le Bail2022-03-251-1/+3
| | | | Update the output of three tests accordingly.
* Kerberos: Remove a redundant bounds checkFrancois-Xavier Le Bail2022-03-251-5/+0
|
* Remove 3 now redundant ND_TCHECK_LEN(e, sizeof(short)) callsFrancois-Xavier Le Bail2020-09-301-2/+0
| | | | | They are redundant because they are identical to ND_TCHECK_2(e), followed by a GET_BE_U_2(e) or a GET_LE_U_2(e), same e, which do the bounds check.
* Remove useless 'return' at end of void functions (style)Francois-Xavier Le Bail2020-09-281-1/+0
|
* Remove many (762) now redundant ND_TCHECK_n() callsFrancois-Xavier Le Bail2020-09-061-6/+0
| | | | | | | | | | | ND_TCHECK_n(e), n in { 1, 2, 3, 4, 8 }. They are redundant because they are followed by a GET_.*_n(e) call, same n, same e, which do the bounds check. Remove unused 'trunc' labels and most associated codes. Update the outputs of some tests accordingly.
* Use more HTTPS in URLsFrancois-Xavier Le Bail2019-08-191-1/+1
| | | | [skip ci]
* Use the new GET_ macros instead of the EXTRACT_ onesFrancois-Xavier Le Bail2019-03-261-11/+11
| | | | | | | The exceptions are currently: Some EXTRACT_ in print-juniper.c, not used on packet buffer pointer. An EXTRACT_BE_U_3 in addrtoname.c, not always used on packet buffer pointer.
* Replace some ND_TTEST_*() with ND_TCHECK_*()Francois-Xavier Le Bail2018-05-181-4/+1
|
* Print truncations with nd_print_trunc() instead of tstr[] stringsFrancois-Xavier Le Bail2018-05-041-5/+4
| | | | | | | | Remove the tstr[] strings. Update the output of some tests accordingly. Moreover: Add or update some ndo_protocol fields.
* Add the ndo_protocol field in the netdissect_options structureFrancois-Xavier Le Bail2018-03-161-0/+1
| | | | | Update this field in printer entry functions. It will be used for some printings.
* Use fn_print_char() to simplify some codeFrancois-Xavier Le Bail2018-02-141-9/+1
|
* Always include <config.h> rather than "config.h".Guy Harris2018-01-211-1/+1
| | | | | | | | This can prevent bizarre failures if, for example, you've done a configuration in the top-level source directory, leaving behind one config.h file, and then do an out-of-tree build in another directory, with different configuration options. This way, we always pick up the same config.h, in the build directory.
* Use quoted include netdissect-stdinc.h instead of angle-bracketed oneFrancois-Xavier Le Bail2018-01-211-1/+1

* Use nd_ types, add EXTRACT_ calls, clean up signed vs. unsigned.Guy Harris2017-12-301-13/+13
|
* Remove all storage class specifier 'register'Francois-Xavier Le Bail2017-12-131-6/+6
| | | | | | Let the compiler do the optimizations (or not) based on build options. Avoid 'value has been optimized out' messages in gdb using '-O0'.
* Replace ND_TTEST2()/ND_TCHECK2() macros by macros using pointers (1/n)Francois-Xavier Le Bail2017-12-111-2/+2
| | | | | ND_TTEST2(var, l) -> ND_TTEST_LEN(p, l) ND_TCHECK2(var, l) -> ND_TCHECK_LEN(p, l)
* Use more the ND_TCHECK_1() macroFrancois-Xavier Le Bail2017-12-041-4/+4

* Use more the EXTRACT_U_1() macro to fetch a one-byte value (26/n)Francois-Xavier Le Bail2017-11-231-1/+2
| | | | | | In ND_PRINT() macro call(s) (step 5). (*(p)++ op e3)
* Rename EXTRACT_ macrosFrancois-Xavier Le Bail2017-11-221-4/+4
| | | | | | | | | | | | | | | | Now all the macros have a name meaning a count in bytes. With _S_: signed, _U_: unsigned e.g.: EXTRACT_BE_32BITS -> EXTRACT_BE_U_4 EXTRACT_LE_32BITS -> EXTRACT_LE_U_4 ... EXTRACT_BE_INT32 -> EXTRACT_BE_S_4 and have: EXTRACT_8BITS -> EXTRACT_U_1 EXTRACT_INT8 -> EXTRACT_S_1
* Use more the EXTRACT_8BITS() macro to fetch a one-byte value (22/n)Francois-Xavier Le Bail2017-11-221-2/+4
| | | | | | In ND_PRINT() macro calls, *p++. Partial list.
* Use more the EXTRACT_8BITS() macro to fetch a one-byte value (17/n)Francois-Xavier Le Bail2017-11-211-1/+2
| | | | | | Assignment, *p++ -> EXTRACT_8BITS(p); p++; Partial list.
* Give documentation for KRB4 and KRB5.Guy Harris2017-11-181-0/+17
|
* Rename EXTRACT_nBITS() macros to EXTRACT_BE_nBITS()Francois-Xavier Le Bail2017-11-181-1/+1
| | | | | It indicates clearly that these macros are used to extract big-endian integral values.
* Move the printer summaries from INSTALL.txt to each printerFrancois-Xavier Le Bail2016-08-141-0/+2
| | | | | | | | with the tag '\summary:' for greping. Remark: Currently some printers have no summary line. Moreover: Summarize all printers with a single line in INSTALL.txt
* Rename 'tcpdump-stdinc.h' to 'netdissect-stdinc.h'Francois-Xavier Le Bail2015-09-101-1/+1
| | | | Get the full log via: git log --follow netdissect-stdinc.h
* Printers must include 'netdissect.h', not 'interface.h'Francois-Xavier Le Bail2015-09-051-1/+1

* Fix a bunch of de-constifications.Guy Harris2015-04-261-2/+2
|
* 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.
* u_intN_t is dead, long live uintN_t.Guy Harris2014-04-231-2/+2
| | | | | | | | | 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.
* spell "%s" format strings (complements 708a68a)Denis Ovsienko2014-03-311-4/+4
| | | | | Make "%s" format string always reside in the print function call explicitly such that the reader doesn't have to assess its safety.
* NDOize AppleTalk, CDP and Kerberos decodersDenis Ovsienko2014-03-281-46/+48

* don't include addrtoname.h needlesslyDenis Ovsienko2014-02-251-1/+0
|
* Do our own isascii(), isprint(), isgraph(), and toascii().Guy Harris2014-02-021-3/+3
| | | | | | | | | We do *not* want the behavior of isprint() and isgraph() to be locale-dependent - we want both of them to return "true" only for ASCII characters. We have to do our own isascii() and toascii() on non-UN*X systems anyway, so let's just do all of them ourselves.
* 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.
* make consistent use of the "tstr" idiomDenis Ovsienko2013-12-261-2/+2
| | | | | | | | For each decoder that has more than one instance of truncation signaling and prints the same string in each instance make sure that the string is declared as "static const char tstr[]" right after the initial includes block. Where necessary, replace fputs(s, stdout) with equivalent printf("%s", s).
* justify declarations of struct tok arraysDenis Ovsienko2013-09-241-2/+2
| | | | | | 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.
* 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 toguy2002-12-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 private unaligned little-endian and big-endian fetch macros;guy2002-12-111-21/+3
| | | | use EXTRACT_LE_16BITS and EXTRACT_16BITS instead.
* put __attribute__((packed)) to packet headers. s/u_short/u_int16_t/ and soitojun2002-11-091-4/+4

* Get rid of the "-Wno-unused" flag, and fix up most of theguy2002-09-051-10/+8
| | | | | | | | | | | | | | | 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".
* Get rid of some unnecessary includes (<time.h>, <netdb.h>, and <ctype.h>guy2002-08-061-2/+1
| | | | | are included by <tcpdump-stdinc.h>, so we don't have to include them explicitly; <errno.h> isn't needed by print routines).

* Add an "ip.h" header, to declare the IP stuff needed by dissectors, andguy2000-09-231-3/+1
| | | | | | | | | | | 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".
* Add "tcp.h" and "udp.h" headers, to declare the TCP and UDP stuff neededguy2000-09-231-3/+1
| | | | | | | | | by dissectors, and have dissectors include them rather than <netinet/udp.h>, <netinet/udp_var.h>, or <netinet/tcp.h>, if they actually need that stuff. Remove all unnecessary includes of <netinet/udp*.h> or <netinet/tcp*.h> files.
