2001-01-22Remove more "CHECK_DISPLAY_AS_DATA()" calls and "pinfo->current_proto ="Guy Harris1-3/+3
statements. Move the setting of the Protocol column in various dissectors before anything is fetched from the packet, and also clear the Info column at that point in those and some other dissectors, so that if an exception is thrown, the columns don't reflect the previous protocol. Make the IP dissector static, as it's called only via dissector tables or dissector handles. Also make the "dissect the TOS field as the DiffServ DS field" flag static, as it's not referred to outside of "packet-ip.c". In the NCP dissector, refer to the port type through "pinfo" rather than through the global "pi", as it's a tvbuffified dissector. svn path=/trunk/; revision=2929
2001-01-09Add an additional "protocol index" argument to "{old_}dissector_add()",Guy Harris1-2/+2
"{old_}heur_dissector_add()", "{old_}conv_dissector_add()", and "register_dissector()", so that an entry in those tables has associated with it the protocol index of the protocol the dissector handles (or -1, if there is no protocol index for it). This is for future use in a number of places. (Arguably, "proto_register_protocol()" should take a dissector pointer as an argument, but 1) it'd have to handle both regular and heuristic dissectors; 2) making it take either a "dissector_t" or a union of that and a "heur_dissector_t" introduces some painful header-file interdependencies so I'm punting on that for now. As with other Ethereal internal APIs, these APIs are subject to change in the future, at least until Ethereal 1.0 comes out....) svn path=/trunk/; revision=2849
2001-01-03Have "proto_register_protocol()" build a list of data structures forGuy Harris1-2/+3
protocols, in addition to adding structures to the list of filterable fields. Give it an extra argument that specifies a "short name" for the protocol, for use in such places as pinfo->current_proto; the dialog box for constructing filters; the preferences tab for the protocol; and so on (although we're not yet using it in all those places). Make the preference name that appears in the preferences file and the command line for the DIAMETER protocol "diameter", not "Diameter"; the convention is that the name in question be all-lower-case. Make some routines and variables that aren't exported static. Update a comment in the ICP dissector to make it clear that the dissector won't see fragments other than the first fragment of a fragmented datagram. svn path=/trunk/; revision=2810

2000-11-19For each column, have both a buffer into which strings for that columnGuy Harris1-2/+2
can be put, and a pointer to the string for the column, which might or might not point to that buffer. Add a routine "col_set_str()", which sets the string for the column to the string passed to it as an argument; it should only be handed a static string (a string constant would be ideal). It doesn't do any copying, so it's faster than "col_add_str()". Make the routines that append to columns check whether the pointer to the string for the column points to the buffer for the column and, if not, copy the string for the column to the buffer for the column so that you can append to it (so you can use "col_set_str()" and then use "col_append_str()" or "col_append_fstr()"). Convert a bunch of "col_add_str()" calls that take a string constant as an argument to "col_set_str()" calls. Convert some "col_add_fstr()" calls that take a string constant as the only argument - i.e., the format string doesn't have any "%" slots into which to put strings for subsequent arguments to "col_set_str()" calls (those calls are just like "col_add_str()" calls). Replace an END_OF_FRAME reference in a tvbuffified dissector with a "tvb_length(tvb)" call. svn path=/trunk/; revision=2670
2000-08-20- proto_bgp was not added in protocol tree, so "bgp" was notLaurent Deniel1-6/+17
working as display filter... - add display filters. svn path=/trunk/; revision=2310
2000-08-13Add the "Edit:Protocols..." feature which currently only implementsLaurent Deniel1-1/+3
the following: It is now possible to enable/disable a particular protocol decoding (i.e. the protocol dissector is void or not). When a protocol is disabled, it is displayed as Data and of course, all linked sub-protocols are disabled as well. Disabling a protocol could be interesting: - in case of buggy dissectors - in case of wrong heuristics - for performance reasons - to decode the data as another protocol (TODO) Currently (if I am not wrong), all dissectors but NFS can be disabled (and dissectors that do not register protocols :-) I do not like the way the RPC sub-dissectors are disabled (in the sub-dissectors) since this could be done in the RPC dissector itself, knowing the sub-protocol hfinfo entry (this is why, I've not modified the NFS one yet). Two functions are added in proto.c : gboolean proto_is_protocol_enabled(int n); void proto_set_decoding(int n, gboolean enabled); and two MACROs which can be used in dissectors: OLD_CHECK_DISPLAY_AS_DATA(index, pd, offset, fd, tree) CHECK_DISPLAY_AS_DATA(index, tvb, pinfo, tree) See also the XXX in proto_dlg.c and proto.c around the new functions. svn path=/trunk/; revision=2267
2000-08-11Miscellaneous code cleaningLaurent Deniel1-12/+8
- add <stdarg.h> or <varargs.h> in snprintf.h and remove those inclusions in the other #ifdef NEED_SNPRINTF_H codes - remove the check of multiple inclusions in source (.c) code (there is a bit loss of _cpp_ performance, but I prefer the gain of code reading and maintenance; and nowadays, disk caches and VM are correctly optimized ;-). - protect all (well almost) header files against multiple inclusions - add header (i.e. GPL license) in some include files - reorganize a bit the way header files are included: First: #include <system_include_files> #include <external_package_include_files (e.g. gtk, glib etc.)> Then #include "ethereal_include_files" with the correct HAVE_XXX or NEED_XXX protections. - add some HAVE_XXX checks before including some system header files - add the same HAVE_XXX in wiretap as in ethereal Please forgive me, if I break something (I've only compiled and regression tested on Linux). svn path=/trunk/; revision=2254
2000-08-07Allow either old-style (pre-tvbuff) or new-style (tvbuffified)Guy Harris1-2/+2
dissectors to be registered as dissectors for particular ports, registered as heuristic dissectors, and registered as dissectors for conversations, and have routines to be used both by old-style and new-style dissectors to call registered dissectors. Have the code that calls those dissectors translate the arguments as necessary. (For conversation dissectors, replace "find_conversation_dissector()", which just returns a pointer to the dissector, with "old_try_conversation_dissector()" and "try_conversation_dissector()", which actually call the dissector, so that there's a single place at which we can do that translation. Also make "dissector_lookup()" static and, instead of calling it and, if it returns a non-null pointer, calling that dissector, just use "old_dissector_try_port()" or "dissector_try_port()", for the same reason.) This allows some dissectors that took old-style arguments and immediately translated them to new-style arguments to just take new-style arguments; make them do so. It also allows some new-style dissectors not to have to translate arguments before calling routines to look up and call dissectors; make them not do so. Get rid of checks for too-short frames in new-style dissectors - the tvbuff code does those checks for you. Give the routines to register old-style dissectors, and to call dissectors from old-style dissectors, names beginning with "old_", with the routines for new-style dissectors not having the "old_". Update the dissectors that use those routines appropriately. Rename "dissect_data()" to "old_dissect_data()", and "dissect_data_tvb()" to "dissect_data()". svn path=/trunk/; revision=2218
2000-05-11Add tvbuff class.Gilbert Ramirez1-87/+87
Add exceptions routines. Convert proto_tree_add_*() routines to require tvbuff_t* argument. Convert all dissectors to pass NULL argument ("NullTVB" macro == NULL) as the tvbuff_t* argument to proto_tree_add_*() routines. dissect_packet() creates a tvbuff_t, wraps the next dissect call in a TRY block, will print "Short Frame" on the proto_tree if a BoundsError exception is caught. The FDDI dissector is converted to use tvbuff's. svn path=/trunk/; revision=1939

2000-04-08Move calls to "dissector_add()" out of the register routines for TCP andGuy Harris1-2/+10
UDP and into the handoff registration routines for the protocols in question. Make the dissectors for those protocols static if they're not called outside the dissector's source file. Get rid of header files if all they did was declare dissectors that are now static; remove declarations of now-static dissectors from header files that do more than just declare the dissector. svn path=/trunk/; revision=1823

2000-01-15Fix up a bunch of places where a pointer into the packet buffer was castGuy Harris1-27/+27
to a type requiring 2-byte or better alignment and was then dereferenced; doing that requires that the code generated by your compiler not trap if it makes an unaligned reference, and on most RISC processors the code generated by the compiler *will* trap on an unaligned reference by default. svn path=/trunk/; revision=1480
2000-01-10Some initial changes for win32 support, but not all.Gilbert Ramirez1-0/+3
Added lots of #ifdef HAVE_*_H wrappers. Added some #defines in config.h.win32 Check for more headers in configure.in Added prototype for inet_aton() in inet_v6defs.h. Changed "BYTE" token (i.e., #define) in ascend-gramamr.y because it conflicts with a windows definition. Use HEXBYTE instead. svn path=/trunk/; revision=1448

- now prints RFC1771 withdrawn prefixes - COMMUNITIES are now fully supported - AS_PATH fixes (output formatting, used snprintf and not sprintf, AS_PATH broken into separate subtree, and for now will ignore confederation types until we support them) - AGGREGATOR fixes, now prints again in tree header - made capitalization consistent (first words capitalized, rest lower case) - lots more commenting - other minor corrections - started work on route reflector attributes From: Greg Hankins <gregh@arthur.twoguys.org> svn path=/trunk/; revision=1090
1999-11-16Replace the ETT_ "enum" members, declared in "packet.h", withGuy Harris1-16/+43
dynamically-assigned "ett_" integer values, assigned by "proto_register_subtree_array()"; this: obviates the need to update "packet.h" whenever you add a new subtree type - you only have to add a call to "proto_register_subtree_array()" to a "register" routine and an array of pointers to "ett_", if they're not already there, and add a pointer to the new "ett_" variable to the array, if they are there; would allow run-time-loaded dissectors to allocate subtree types when they're loaded. svn path=/trunk/; revision=1043
