* Replace the types from sys/types.h and netinet/in.h by their glib.hJörg Mayer2002-08-021-11/+3
| | | | | | | | equivalents for the toplevel directory. The removal of winsock2.h will hopefully not cause any problems under MSVC++, as those files using struct timeval still include wtap.h, which still includes winsock2.h. svn path=/trunk/; revision=5932

In any case, not all platforms on which Ethereal can be built support 64-bit integral data types, and, even on those that do, not all of them support "%ll[doux]" as the format for printing those types, so do the arithmetic in floating point by multiplying the bytes/s values by 8.0, and print with "%.0f" instead. svn path=/trunk/; revision=4731

* Replace a bunch of "tvb_length()" and "tvb_length_remaining()" calls inGuy Harris2002-01-241-10/+4
| | | | | | | | | | | | arguments to "proto_tree_add_text()", and to "proto_tree_add_XXX()" calls that add FT_NONE or FT_PROTO items to the protocol tree, with -1. Replace some calls to "tvb_length()" or "tvb_length_remaining()" with calls to "tvb_reported_length()" and "tvb_reported_length_remaining()", as those give the actual length of the data in the packet, not just the data that happened to be captured. svn path=/trunk/; revision=4605
* Include files from the "epan" directory and subdirectories thereof withGuy Harris2002-01-211-2/+2
| | | | | | | | | | | | | "epan/..." pathnames, so as to avoid collisions with header files in any of the directories in which we look (e.g., "proto.h", as some other package has its own "proto.h" file which it installs in the top-level include directory). Don't add "-I" flags to search "epan", as that's no longer necessary (and we want includes of "epan" headers to fail if the "epan/" is left out, so that we don't re-introduce includes lacking "epan/"). svn path=/trunk/; revision=4586
* Move the pointer to the "column_info" structure in the "frame_data"Guy Harris2001-12-101-7/+7
| | | | | | | | | | | | | | | structure to the "packet_info" structure; only stuff that's permanently stored with each frame should be in the "frame_data" structure, and the "column_info" structure is not guaranteed to hold the column values for that frame at all times - it was only in the "frame_data" structure so that it could be passed to dissectors, and, as all dissectors are now passed a pointer to a "packet_info" structure, it could just as well be put in the "packet_info" structure. That saves memory, by shrinking the "frame_data" structure (there's one of those per frame), and also lets us clean up the code a bit. svn path=/trunk/; revision=4370

* Tvbuffify the RSVP dissector.Guy Harris2001-02-041-4/+4
| | | | | | | | | | | Display the message checksum, and check it if possible. Fix some IPv6 entries to be 16 bytes long, not 4 bytes long. Make the routine to fetch an IEEE floating point number and turn it into a "long" take a tvbuff pointer and offset rather than a pointer to data. svn path=/trunk/; revision=2987
* Remove more "CHECK_DISPLAY_AS_DATA()" calls and "pinfo->current_proto ="Guy Harris2001-01-221-6/+5
| | | | | | | | | | | | | | | | | | | 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
* Add an additional "protocol index" argument to "{old_}dissector_add()",Guy Harris2001-01-091-2/+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
* Ensure that all value_string arrays end in {0, NULL}. Dissectors got awayGilbert Ramirez2001-01-031-1/+2
| | | | | | | | | | | | | | with not terminating their arrays because they knew the limits of the value used to look up strings in the value_string array, but the dfilter_expr_dlg does not know these limits and must rely on the terminating {0, NULL} record. Also, in SNA fixed a bug in which a field should have been defined as FT_UINT8 but was defined as FT_BOOLEAN. In WTP, fixed a value string which had duplicate keys. svn path=/trunk/; revision=2817
* Have "proto_register_protocol()" build a list of data structures forGuy Harris2001-01-031-2/+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

* Tvbuffify the RIP and OSPF dissectors.Guy Harris2000-12-271-645/+742
| | | | | | | | | | | | | | | | | | | | | Change them to use facilities in Ethereal that were probably not present when they were originally written, e.g. routines to fetch 24-bit integers and to dump a bunch of raw bytes in hex. Redo them to extract data from the packet as they dissect it, rather than extracting an entire data structure at once; that way, it may be able to dissect a structure not all of which is in the packet. Dissect a bit more of the type-of-service metrics etc. in OSPF packets. Make "tvb_length_remaining()" return a "gint", not a "guint"; it returns -1 if the offset is past the end of the tvbuff. Add a "tvb_reported_length_remaining()" routine, similar to "tvb_length_remaining()". Use it instead of just subtracting an offset from "tvb_reported_length()". svn path=/trunk/; revision=2787
* Check the checksum on OSPF packets, if possible.Guy Harris2000-12-141-3/+44

* For each column, have both a buffer into which strings for that columnGuy Harris2000-11-191-2/+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
* Changes from Craig Metz to:Guy Harris2000-09-131-2/+6

* Add the "Edit:Protocols..." feature which currently only implementsLaurent Deniel2000-08-131-1/+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
* Allow either old-style (pre-tvbuff) or new-style (tvbuffified)Guy Harris2000-08-071-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Enhancements/fixed to OSPF from Michael Rozhavsky:Guy Harris2000-07-141-3/+9

* Add routines for adding items to a protocol tree that take arguments ofGuy Harris2000-05-311-2/+2
| | | | | | | | | | | | | | | | | a particular type, rather than taking a varargs list, along the lines of the "proto_tree_add_XXX_format()" routines. Replace most calls to "proto_tree_add_item()" and "proto_tree_add_item_hidden()" with calls to those routines. Rename "proto_tree_add_item()" and "proto_tree_add_item_hidden()" to "proto_tree_add_item_old()" and "proto_tree_add_item_hidden_old()", and add new "proto_tree_add_item()" and "proto_tree_add_item_hidden()" routines that don't take the item to be added as an argument - instead, they fetch the argument from the packet whose tvbuff was handed to them, from the offset handed to them. svn path=/trunk/; revision=2031
* Add tvbuff class.Gilbert Ramirez2000-05-111-114/+114
| | | | | | | | | | | | | | | 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
* Register an "ip.proto" dissector table for IPv4, and have dissectors forGuy Harris2000-04-161-8/+28
| | | | | | | | | | protocols that run inside IPv4 register themselves with it using "dissector_add()". Make various dissectors static if they can be, and get rid of any header files that no longer contain any information as a result of that change. svn path=/trunk/; revision=1870
* Fix some errors discovered by making GCC do format string/argumentGuy Harris2000-03-141-4/+4
| | | | | | | | | | | | | | | cross-checking, and by replacing "proto_tree_add_item_format()" by multiple routines to add items of various types. Make the arguments of "proto_tree_add_bytes_format()" and "proto_tree_add_string_format()" that specify the bytes or the string be "const" pointers, so that one can pass a "const" pointer without complaints from the compiler. Squelch a (bogus, but the compiler isn't in a position to know that) complaint about an uninitialized variable. svn path=/trunk/; revision=1716
